We report an efficient and facile approach to biosynthesis of gold nanoparticles (AuNPs) using the extract of an agro-waste rice husk generated from rice production. The biosynthesized NPs produced were characterized by UV-Visible absorption, TEM, XRD, EDX, and FTIR methods. The impact of temperature and pH on the stability of the synthesized AuNPs was also studied. The TEM imaging revealed the formation of monodispersed spherical NPs with an average size of ~ 15 nm. The absorption spectrum of AuNPs demonstrated the formation of Surface Plasmon Resonance (SPR) peak at 530 nm. The XRD pattern suggested the formation of face-centered cubic (FCC) lattice structure of AuNPs. The FTIR analysis displayed characteristic peaks related to various phytochemicals in the plant extract responsible for reducing and stabilizing NPs. In addition, AuNPs showed thermal stability when subjected to various temperature scales. The AuNPs exhibited an efficiency against the pathogenic bacteria Staphylococcus aureus and pathogenic fungi Candida albicans. The AuNPs 18.5% DPPH free scavenging activity, indicating the antioxidant potential for AuNPs. In addition, the AuNPs showed anticancer activity against the colorectal adenocarcinoma carcinoma cell line. Furthermore, AuNPs displayed significant enhancement in photocatalytic degradation of Methylene Blue and 4-Nitrophenol dyes. The results obtained reveal the possible usage of AuNPs produced using rice husk in several biomedical applications.

Kassem; Roshan K. Nayak; Muhammad Muddassir;Climate change constitutes a major threat to agricultural production, food security, and natural resource management. Saudi Arabia is particularly susceptible to increasing temperatures and extreme climatic events, such as arid weather and drought. The purpose of this study is to assess farmers’ beliefs and concerns as regards climate change. Extensive interviews were conducted with 164 farmers in the Jazan region. Results revealed that 89.6% of the farmers believed that climate change is due to human activities and 93.3% believed that it is because of natural change. Seventy-five percent of the farmers were concerned about insects and 73% about the prevalence of weeds on their farms. Findings of cluster analysis revealed that farmers who are more likely to believe in climate change are more in agreement with the role of extension services in capacity building. Farmers’ beliefs about climate change were significantly influenced by membership of agricultural cooperatives, access to loans, use of extension services, age, farm size, and level of soil fertility. Access to loans was the only significant factor to explain the differences in farmers’ concerns. These results suggest the need for capacity-building activities targeted at improving farmers’ adaptability to manage climate variability.

Jatropha curcas L. (Jatropha), une espèce arbustive de la famille des Euphorbiaceae, a été reconnue comme une usine de biocarburants prometteuse pour réduire les émissions de gaz à effet de serre. Cependant, les récentes tentatives de culture commerciale en Afrique et en Asie ont échoué en raison de la faible productivité. Il est important d'élucider la diversité génétique et la relation dans les ressources génétiques mondiales de Jatropha pour la sélection de meilleurs cultivars commerciaux. Ici, la diversité génétique a été analysée en utilisant 246 accessions de la Méso-Amérique, de l'Afrique et de l'Asie, sur la base de 59 marqueurs de répétition de séquence simple et de huit marqueurs de polymorphisme d'insertion à base de rétrotransposons. Nous avons constaté que le Chiapas central du Mexique possède les ressources génétiques les plus diverses, et la dépression centrale du Chiapas pourrait être le centre d'origine. Nous avons identifié trois groupes génétiques en Méso-Amérique, dont la répartition a révélé un cline géographique distinct. L'un d'eux consiste principalement en des adhésions du centre du Chiapas. Cela suggère qu'il représente le groupe génétique d'origine. Nous avons trouvé deux accessions Veracruz dans un autre groupe, dont les ancêtres pourraient être expédiés du port de Veracruz vers l'Ancien Monde, pour être la source de tous les Jatropha africains et asiatiques. Nos résultats suggèrent la sélection humaine qui a causé une faible productivité en Afrique et en Asie, ainsi que des stratégies de sélection pour améliorer le jatropha africain et asiatique. Les cultivars améliorés dans la productivité contribueront à développer la culture commerciale de masse du Jatropha en Afrique et en Asie pour augmenter la production de biocarburants, et enfin soutiendront la lutte contre le changement climatique. Jatropha curcas L. (Jatropha), una especie de arbusto de la familia Euphorbiaceae, ha sido reconocida como una planta de biocombustible prometedora para reducir las emisiones de gases de efecto invernadero. Sin embargo, los recientes intentos de cultivo comercial en África y Asia han fracasado debido a la baja productividad.

Encontramos que el centro de Chiapas de México posee los recursos genéticos más diversos, y la Depresión Central de Chiapas podría ser el centro de origen. Identificamos tres grupos genéticos en Mesoamérica, cuya distribución reveló un clino geográfico distinto. Uno de ellos consiste principalmente en accesiones desde el centro de Chiapas. Esto sugiere que representa el grupo genético original. Encontramos dos accesiones de Veracruz en otro grupo, cuyos antepasados podrían ser enviados desde el Puerto de Veracruz al Viejo Mundo, para ser la fuente de toda la jatrofa africana y asiática. Nuestros resultados sugieren la selección humana que causó la baja productividad en África y Asia, y también estrategias de cría para mejorar la jatrofa africana y asiática. Los cultivos mejorados en la productividad contribuirán a expandir el cultivo comercial masivo de Jatropha en África y Asia para aumentar la producción de biocombustibles, y finalmente apoyarán en la batalla contra el cambio climático. Jatropha curcas L. (Jatropha), a shrub species of the family Euphorbiaceae, has been recognized as a promising biofuel plant for reducing greenhouse gas emissions. However, recent attempts at commercial cultivation in Africa and Asia have failed because of low productivity. It is important to elucidate genetic diversity and relationship in worldwide Jatropha genetic resources for breeding of better commercial cultivars. Here, genetic diversity was analyzed by using 246 accessions from Mesoamerica, Africa and Asia, based on 59 simple sequence repeat markers and eight retrotransposon-based insertion polymorphism markers. We found that central Chiapas of Mexico possesses the most diverse genetic resources, and the Chiapas Central Depression could be the center of origin. We identified three genetic groups in Mesoamerica, whose distribution revealed a distinct geographic cline. One of them consists mainly of accessions from central Chiapas. This suggests that it represents the original genetic group. We found two Veracruz accessions in another group, whose ancestors might be shipped from Port of Veracruz to the Old World, to be the source of all African and Asian Jatropha. Our results suggest the human selection that caused low productivity in Africa and Asia, and also breeding strategies to improve African and Asian Jatropha. Cultivars improved in the productivity will contribute to expand mass commercial cultivation of Jatropha in Africa and Asia to increase biofuel production, and finally will support in the battle against the climate change. Jatropha curcas L. (Jatropha)، وهو نوع من الشجيرات من عائلة Euphorbiaceae، تم الاعتراف به كمصنع واعد للوقود الحيوي لتقليل انبعاثات غازات الدفيئة. ومع ذلك، فشلت المحاولات الأخيرة للزراعة التجارية في أفريقيا وآسيا بسبب انخفاض الإنتاجية. من المهم توضيح التنوع الوراثي والعلاقة في الموارد الوراثية للجاتروفا في جميع أنحاء العالم لتربية أصناف تجارية أفضل. هنا، تم تحليل التنوع الجيني باستخدام 246 ملحقًا من أمريكا الوسطى وأفريقيا وآسيا، استنادًا إلى 59 علامة تكرار تسلسل بسيطة وثمانية علامات تعدد أشكال الإدراج القائمة على الترانسبروسون. وجدنا أن وسط تشياباس في المكسيك يمتلك الموارد الجينية الأكثر تنوعًا، ويمكن أن يكون الكساد المركزي في تشياباس هو مركز المنشأ. حددنا ثلاث مجموعات وراثية في أمريكا الوسطى، والتي كشف توزيعها عن سلالة جغرافية متميزة. يتكون أحدها بشكل أساسي من المنضمين من وسط تشياباس. هذا يشير إلى أنه يمثل المجموعة الوراثية الأصلية. وجدنا انضمامين لفيراكروز في مجموعة أخرى، قد يتم شحن أسلافهم من ميناء فيراكروز إلى العالم القديم، ليكونوا مصدر كل الجاتروفا الأفريقية والآسيوية. تشير نتائجنا إلى الانتقاء البشري الذي تسبب في انخفاض الإنتاجية في أفريقيا وآسيا، وكذلك استراتيجيات التكاثر لتحسين الجاتروفا الأفريقية والآسيوية. ستساهم الأصناف المحسنة في الإنتاجية في توسيع الزراعة التجارية الجماعية للجاتروفا في إفريقيا وآسيا لزيادة إنتاج الوقود الحيوي، وأخيرًا ستدعم المعركة ضد تغير المناخ.

(Jatropha)، وهو نوع من الشجيرات من عائلة Euphorbiaceae، تم الاعتراف به كمصنع واعد للوقود الحيوي لتقليل انبعاثات غازات الدفيئة. ومع ذلك، فشلت المحاولات الأخيرة للزراعة التجارية في أفريقيا وآسيا بسبب انخفاض الإنتاجية. من المهم توضيح التنوع الوراثي والعلاقة في الموارد الوراثية للجاتروفا في جميع أنحاء العالم لتربية أصناف تجارية أفضل. هنا، تم تحليل التنوع الجيني باستخدام 246 ملحقًا من أمريكا الوسطى وأفريقيا وآسيا، استنادًا إلى 59 علامة تكرار تسلسل بسيطة وثمانية علامات تعدد أشكال الإدراج القائمة على الترانسبروسون. وجدنا أن وسط تشياباس في المكسيك يمتلك الموارد الجينية الأكثر تنوعًا، ويمكن أن يكون الكساد المركزي في تشياباس هو مركز المنشأ. حددنا ثلاث مجموعات وراثية في أمريكا الوسطى، والتي كشف توزيعها عن سلالة جغرافية متميزة. يتكون أحدها بشكل أساسي من المنضمين من وسط تشياباس. هذا يشير إلى أنه يمثل المجموعة الوراثية الأصلية. وجدنا انضمامين لفيراكروز في مجموعة أخرى، قد يتم شحن أسلافهم من ميناء فيراكروز إلى العالم القديم، ليكونوا مصدر كل الجاتروفا الأفريقية والآسيوية. تشير نتائجنا إلى الانتقاء البشري الذي تسبب في انخفاض الإنتاجية في أفريقيا وآسيا، وكذلك استراتيجيات التكاثر لتحسين الجاتروفا الأفريقية والآسيوية. ستساهم الأصناف المحسنة في الإنتاجية في توسيع الزراعة التجارية الجماعية للجاتروفا في إفريقيا وآسيا لزيادة إنتاج الوقود الحيوي، وأخيرًا ستدعم المعركة ضد تغير المناخ.

Nowadays, gastric ulcers have become very common gastrointestinal disorders and numerous natural plant extracts exert promising anti-ulcerative effects. Therefore, this study was designed to evaluate the possible protective effect of dietary starch against ethanol induced gastric ulcers in mice. Post-administration of dietary starch for three consecutive days caused remarkable ameliorations in hemorrhagic lesions in gastric mucus and significant suppression in % incidence of ulceration, ulcer index and ulcer score induced by ethanol single administration. Indeed, deep ulceration, necrosis, disruption and degeneration in large areas of mucosa layer together with dense inflammatory cells infiltration and edema in sub-mucosal layer induced by ethanol administration were attenuated by starch post-administration and normalized the tissue architecture of the stomach. This potential protective effect could be attributed to the potent anti-oxidative capacity of starch that causes scavenger of the reactive oxygen species and thereby decreasing single and double DNA stranded break inductions and apoptotic DNA damage revealed by returning the p53 and caspase-3 expression levels to the normal level compared to the ethanol treated group. In conclusion, dietary starch has a potent therapeutic effect against ethanol induced gastric ulcer in mice via its free radical scavengers ability. Thus, we recommended further studies on its possible use as antiulcer drugs.

Despite being a religious country, the Kingdom of Saudi Arabia (KSA) ranks among the world’s worst food wasters. Social media usage (SMU) and changes in customers’ behavior, such as excessive buying, are some of the main influences of food waste. This paper examined the impact of SMU on food waste intention (FWI) with the mediating role of religiosity and excessive buying behavior amid the coronavirus (COVID-19) pandemic. A self-administered questionnaire was completed by 1250 restaurant customers in KSA. The study results employing structural equation modeling (SEM) demonstrated a significant negative impact of customer religion on the intention of food waste. Nevertheless, SMU fosters excessive buying, which in return results in a high FWI. The results also demonstrated that excessive buying behaviors partially mediate the influence of SMU and religiosity on the intention of food waste. The findings have numerous implications for policymakers, academics, and restaurant professionals.

Alminderej; Zeineb Hamden; Yassine El-Ghoul; Bechir Hammami; Sayed M. Saleh; Hatem Majdoub;Given crude oil prices and their environmental impacts, the use of sustainable renewable alternative energies such as biofuels is rapidly progressing in numerous countries. Among biofuels, bioethanol is a renewable and clean fuel that can be obtained from the fermentation of several raw agricultural materials, including date fruit. However, the low product yield, mainly due to the low-grade nutrient content, limits its use as a promising alternative biofuel. This current study investigated bioethanol production from date by-products in Saudi Arabia and examined the impact of calcium and nitrogen sources added at different concentrations (0 to 1 g/L) on the productivity and ethanol concentration using Saccharomyces cerevisiae. Yeast extracts and ammonium chloride (NH4Cl) were tested as nitrogen sources for bioethanol fermentation from date juice. Calcium chloride (CaCl2) and calcium carbonate (CaCO3) were evaluated as calcium sources for the same purpose mentioned above. The results showed that both calcium and nitrogen sources improved ethanol production efficiencies. The addition of calcium sources such as CaCl2 at 0.4 g/L resulted in maximum ethanol concentration (41.5 ± 0.85 g/L) and the highest productivity of 0.511 g/L/h. Thus, an increase of 31.3% compared to the control sample was acquired. Ammonium chloride was found to be the best nitrogen supplement among them. Indeed, supplementing the fermentation medium with 1 g/L NH4Cl gave an optimal ethanol concentration and productivity, reaching more than 65 g/L and 0.83 g/L/h, respectively. This is an increase of 106.6%. The functional group of ethanol (C2H5OH) for all the elaborated samples was confirmed by Fourier-transform infrared spectroscopy (FTIR) and NMR analyses. Moreover, the results confirmed the high quality and purity of the bioethanol products. Thus, the “Khodhari” date variety of low market value is a privileged substrate for industrial bioethanol production. For this reason, a proposed flow diagram of a designed plant for bioethanol industrialization is provided and detailed.

Soliman; Mahmoud Elsayed; Mahmoud Elsayed; Ramadan Hassany;This paper mainly introduces the potential of methane yield from co-digestion of primary sludge (PS) and the proposed new waste materials of sugarcane leaves (SL) and Corchorus stalks (CS) in Egypt. This paper includes three parts. In the first part, anaerobic co-digestion of PS, SL, and CS at different carbon-to-nitrogen (C/N) ratios was studied to determine the best C/N ratio. The results indicated that the maximum cumulative methane yields (CMYs) were observed at a C/N ratio of 18, which was associated with the highest volatile solid (VS) removal rate (74.41%). In the second part, the effect of using two types of inoculum (fresh cow manure (CM) and rumen content from slaughterhouses (RS)) on increasing the production of methane was investigated. Clearly, using CM as inoculum showed a superiority of the production of methane from co-digestion of PS, SL, and CS. The maximum CMYs were observed using the CM as inoculum from co-digestion of PS, SL, and CS. It was higher about 1.26 times more CMY using RS as inoculum. In the third part, the possibility of enhancing biogas yields from semi-continuous co-digestion of PS, SL, and CS using different organic loading rates (OLR) of 0.5, 1.0, and 2.0 was conducted. The highest biogas production rate was observed at an OLR of 1.0 gVS/(Lreactor.d) that coincided with the optimum VS removal rate. Statistical analysis of the results was conducted using analysis of variance (ANOVA) test, and the C/N ratio of 18 is statistically the best enhanced ratio. Overall, the feasibility of maximizing the methane productivity considering the anaerobic co-digestion of PS, SL, and CS under the optimal operating conditions and configuration was proved.

Mousa; N. S. Elkaoud; S. H. Dosoky;This study was conducted to investigate physical, mechanical and aerodynamic properties of Jatropha seeds cultivated in Egypt. The properties were determined at moisture content of Jatropha seed 8.25 (%, d. b.). The results showed that the mean values of the %-ages by weight of seed parts to whole seed was 60.84 and 39.16 % for kernels and husks, respectively. The results also include the following properties; length, width, thickness, arithmetic and geometric mean diameter, sphericity, aspect ratio, mass of individual seed, thousand seed mass, true density, bulk density, porosity, surface area, specific surface area and projected area; their averages were found to be 17.28 mm, 11.06 mm, 8.11 mm, 12.15 mm, 11.57 mm, 67.05 %, 64.18 %, 0.598 g, 551.1 g, 0.713 g/cm3, 0.425 g/cm3, 39.89%, 421.6 mm2, 3.08 cm2/cm3 and 154.4 mm2, respectively. The mean value of angle of repose was 0.466 rad. For the coefficient of static friction; the stainless steel surface had the lowest value (0.196) while; the Plexi-glass surface had the highest value (0.403). The highest values of the rupture force, deformation ratio, hardness and the energy needed for rupture force were 101.3 N, 0.13, 105.17 N/mm and 61.7 N.mm while; The lowest values were 57.0 N, 0.05, 99.17 N/mm and 19.1 N.mm, respectively. The average values of terminal velocity and coefficient of drag were 14.27 m/s and 0.30, respectively. Also; the average value of Reynolds number was 10898 therefore; the pattern of air flow is turbulent.

The influence of densification parameters on the quality properties of rice straw pellets was the main focus of this study. The conditioning factors analyzed were: moisture content of the feeding material (12%, 15% and 17%), starch as an additive (0%, 1% and 2%), operating temperature (below and over 50 °C), and the influence of three flat dies with different diameter/compression length (6/20, 6/24 and 8/32 mm/mm) on the pellet properties (durability, hardness, moisture content, dimension, and single and bulk densities). The quality of the pellets was evaluated in view of current standards. The results showed that the studied feeding and operating conditions had significant effects on the pellet properties, especially durability and bulk density, which are the most important parameters for pellet quality. All dimensions, most bulk densities, and few durability values of the produced pellets achieved the standard limits. The highest pellet quality, with durability 99.31%, was obtained with operating conditions 2% starch ratio, 17% feeding moisture content, temperature

We report an efficient and facile approach to biosynthesis of gold nanoparticles (AuNPs) using the extract of an agro-waste rice husk generated from rice production. The biosynthesized NPs produced were characterized by UV-Visible absorption, TEM, XRD, EDX, and FTIR methods. The impact of temperature and pH on the stability of the synthesized AuNPs was also studied. The TEM imaging revealed the formation of monodispersed spherical NPs with an average size of ~ 15 nm. The absorption spectrum of AuNPs demonstrated the formation of Surface Plasmon Resonance (SPR) peak at 530 nm. The XRD pattern suggested the formation of face-centered cubic (FCC) lattice structure of AuNPs. The FTIR analysis displayed characteristic peaks related to various phytochemicals in the plant extract responsible for reducing and stabilizing NPs. In addition, AuNPs showed thermal stability when subjected to various temperature scales. The AuNPs exhibited an efficiency against the pathogenic bacteria Staphylococcus aureus and pathogenic fungi Candida albicans. The AuNPs 18.5% DPPH free scavenging activity, indicating the antioxidant potential for AuNPs. In addition, the AuNPs showed anticancer activity against the colorectal adenocarcinoma carcinoma cell line. Furthermore, AuNPs displayed significant enhancement in photocatalytic degradation of Methylene Blue and 4-Nitrophenol dyes. The results obtained reveal the possible usage of AuNPs produced using rice husk in several biomedical applications.

Kassem; Roshan K. Nayak; Muhammad Muddassir;Climate change constitutes a major threat to agricultural production, food security, and natural resource management. Saudi Arabia is particularly susceptible to increasing temperatures and extreme climatic events, such as arid weather and drought. The purpose of this study is to assess farmers’ beliefs and concerns as regards climate change. Extensive interviews were conducted with 164 farmers in the Jazan region. Results revealed that 89.6% of the farmers believed that climate change is due to human activities and 93.3% believed that it is because of natural change. Seventy-five percent of the farmers were concerned about insects and 73% about the prevalence of weeds on their farms. Findings of cluster analysis revealed that farmers who are more likely to believe in climate change are more in agreement with the role of extension services in capacity building. Farmers’ beliefs about climate change were significantly influenced by membership of agricultural cooperatives, access to loans, use of extension services, age, farm size, and level of soil fertility. Access to loans was the only significant factor to explain the differences in farmers’ concerns. These results suggest the need for capacity-building activities targeted at improving farmers’ adaptability to manage climate variability.

Jatropha curcas L. (Jatropha), une espèce arbustive de la famille des Euphorbiaceae, a été reconnue comme une usine de biocarburants prometteuse pour réduire les émissions de gaz à effet de serre. Cependant, les récentes tentatives de culture commerciale en Afrique et en Asie ont échoué en raison de la faible productivité. Il est important d'élucider la diversité génétique et la relation dans les ressources génétiques mondiales de Jatropha pour la sélection de meilleurs cultivars commerciaux. Ici, la diversité génétique a été analysée en utilisant 246 accessions de la Méso-Amérique, de l'Afrique et de l'Asie, sur la base de 59 marqueurs de répétition de séquence simple et de huit marqueurs de polymorphisme d'insertion à base de rétrotransposons. Nous avons constaté que le Chiapas central du Mexique possède les ressources génétiques les plus diverses, et la dépression centrale du Chiapas pourrait être le centre d'origine. Nous avons identifié trois groupes génétiques en Méso-Amérique, dont la répartition a révélé un cline géographique distinct. L'un d'eux consiste principalement en des adhésions du centre du Chiapas. Cela suggère qu'il représente le groupe génétique d'origine. Nous avons trouvé deux accessions Veracruz dans un autre groupe, dont les ancêtres pourraient être expédiés du port de Veracruz vers l'Ancien Monde, pour être la source de tous les Jatropha africains et asiatiques. Nos résultats suggèrent la sélection humaine qui a causé une faible productivité en Afrique et en Asie, ainsi que des stratégies de sélection pour améliorer le jatropha africain et asiatique. Les cultivars améliorés dans la productivité contribueront à développer la culture commerciale de masse du Jatropha en Afrique et en Asie pour augmenter la production de biocarburants, et enfin soutiendront la lutte contre le changement climatique.

Sin embargo, los recientes intentos de cultivo comercial en África y Asia han fracasado debido a la baja productividad. Es importante dilucidar la diversidad genética y la relación en los recursos genéticos mundiales de Jatropha para la reproducción de mejores cultivares comerciales. Aquí, se analizó la diversidad genética mediante el uso de 246 accesiones de Mesoamérica, África y Asia, basadas en 59 marcadores de repetición de secuencia simple y ocho marcadores de polimorfismo de inserción basados en retrotransposones. Encontramos que el centro de Chiapas de México posee los recursos genéticos más diversos, y la Depresión Central de Chiapas podría ser el centro de origen. Identificamos tres grupos genéticos en Mesoamérica, cuya distribución reveló un clino geográfico distinto. Uno de ellos consiste principalmente en accesiones desde el centro de Chiapas. Esto sugiere que representa el grupo genético original. Encontramos dos accesiones de Veracruz en otro grupo, cuyos antepasados podrían ser enviados desde el Puerto de Veracruz al Viejo Mundo, para ser la fuente de toda la jatrofa africana y asiática. Nuestros resultados sugieren la selección humana que causó la baja productividad en África y Asia, y también estrategias de cría para mejorar la jatrofa africana y asiática. Los cultivos mejorados en la productividad contribuirán a expandir el cultivo comercial masivo de Jatropha en África y Asia para aumentar la producción de biocombustibles, y finalmente apoyarán en la batalla contra el cambio climático. Jatropha curcas L. (Jatropha), a shrub species of the family Euphorbiaceae, has been recognized as a promising biofuel plant for reducing greenhouse gas emissions. However, recent attempts at commercial cultivation in Africa and Asia have failed because of low productivity. It is important to elucidate genetic diversity and relationship in worldwide Jatropha genetic resources for breeding of better commercial cultivars. Here, genetic diversity was analyzed by using 246 accessions from Mesoamerica, Africa and Asia, based on 59 simple sequence repeat markers and eight retrotransposon-based insertion polymorphism markers. We found that central Chiapas of Mexico possesses the most diverse genetic resources, and the Chiapas Central Depression could be the center of origin. We identified three genetic groups in Mesoamerica, whose distribution revealed a distinct geographic cline. One of them consists mainly of accessions from central Chiapas. This suggests that it represents the original genetic group. We found two Veracruz accessions in another group, whose ancestors might be shipped from Port of Veracruz to the Old World, to be the source of all African and Asian Jatropha. Our results suggest the human selection that caused low productivity in Africa and Asia, and also breeding strategies to improve African and Asian Jatropha. Cultivars improved in the productivity will contribute to expand mass commercial cultivation of Jatropha in Africa and Asia to increase biofuel production, and finally will support in the battle against the climate change. Jatropha curcas L. (Jatropha)، وهو نوع من الشجيرات من عائلة Euphorbiaceae، تم الاعتراف به كمصنع واعد للوقود الحيوي لتقليل انبعاثات غازات الدفيئة. ومع ذلك، فشلت المحاولات الأخيرة للزراعة التجارية في أفريقيا وآسيا بسبب انخفاض الإنتاجية. من المهم توضيح التنوع الوراثي والعلاقة في الموارد الوراثية للجاتروفا في جميع أنحاء العالم لتربية أصناف تجارية أفضل. هنا، تم تحليل التنوع الجيني باستخدام 246 ملحقًا من أمريكا الوسطى وأفريقيا وآسيا، استنادًا إلى 59 علامة تكرار تسلسل بسيطة وثمانية علامات تعدد أشكال الإدراج القائمة على الترانسبروسون. وجدنا أن وسط تشياباس في المكسيك يمتلك الموارد الجينية الأكثر تنوعًا، ويمكن أن يكون الكساد المركزي في تشياباس هو مركز المنشأ. حددنا ثلاث مجموعات وراثية في أمريكا الوسطى، والتي كشف توزيعها عن سلالة جغرافية متميزة. يتكون أحدها بشكل أساسي من المنضمين من وسط تشياباس. هذا يشير إلى أنه يمثل المجموعة الوراثية الأصلية. وجدنا انضمامين لفيراكروز في مجموعة أخرى، قد يتم شحن أسلافهم من ميناء فيراكروز إلى العالم القديم، ليكونوا مصدر كل الجاتروفا الأفريقية والآسيوية. تشير نتائجنا إلى الانتقاء البشري الذي تسبب في انخفاض الإنتاجية في أفريقيا وآسيا، وكذلك استراتيجيات التكاثر لتحسين الجاتروفا الأفريقية والآسيوية. ستساهم الأصناف المحسنة في الإنتاجية في توسيع الزراعة التجارية الجماعية للجاتروفا في إفريقيا وآسيا لزيادة إنتاج الوقود الحيوي، وأخيرًا ستدعم المعركة ضد تغير المناخ.

Nowadays, gastric ulcers have become very common gastrointestinal disorders and numerous natural plant extracts exert promising anti-ulcerative effects. Therefore, this study was designed to evaluate the possible protective effect of dietary starch against ethanol induced gastric ulcers in mice. Post-administration of dietary starch for three consecutive days caused remarkable ameliorations in hemorrhagic lesions in gastric mucus and significant suppression in % incidence of ulceration, ulcer index and ulcer score induced by ethanol single administration. Indeed, deep ulceration, necrosis, disruption and degeneration in large areas of mucosa layer together with dense inflammatory cells infiltration and edema in sub-mucosal layer induced by ethanol administration were attenuated by starch post-administration and normalized the tissue architecture of the stomach. This potential protective effect could be attributed to the potent anti-oxidative capacity of starch that causes scavenger of the reactive oxygen species and thereby decreasing single and double DNA stranded break inductions and apoptotic DNA damage revealed by returning the p53 and caspase-3 expression levels to the normal level compared to the ethanol treated group. In conclusion, dietary starch has a potent therapeutic effect against ethanol induced gastric ulcer in mice via its free radical scavengers ability. Thus, we recommended further studies on its possible use as antiulcer drugs.

Despite being a religious country, the Kingdom of Saudi Arabia (KSA) ranks among the world’s worst food wasters. Social media usage (SMU) and changes in customers’ behavior, such as excessive buying, are some of the main influences of food waste. This paper examined the impact of SMU on food waste intention (FWI) with the mediating role of religiosity and excessive buying behavior amid the coronavirus (COVID-19) pandemic. A self-administered questionnaire was completed by 1250 restaurant customers in KSA. The study results employing structural equation modeling (SEM) demonstrated a significant negative impact of customer religion on the intention of food waste. Nevertheless, SMU fosters excessive buying, which in return results in a high FWI. The results also demonstrated that excessive buying behaviors partially mediate the influence of SMU and religiosity on the intention of food waste. The findings have numerous implications for policymakers, academics, and restaurant professionals.

Alminderej; Zeineb Hamden; Yassine El-Ghoul; Bechir Hammami; Sayed M. Saleh; Hatem Majdoub;Given crude oil prices and their environmental impacts, the use of sustainable renewable alternative energies such as biofuels is rapidly progressing in numerous countries. Among biofuels, bioethanol is a renewable and clean fuel that can be obtained from the fermentation of several raw agricultural materials, including date fruit. However, the low product yield, mainly due to the low-grade nutrient content, limits its use as a promising alternative biofuel. This current study investigated bioethanol production from date by-products in Saudi Arabia and examined the impact of calcium and nitrogen sources added at different concentrations (0 to 1 g/L) on the productivity and ethanol concentration using Saccharomyces cerevisiae. Yeast extracts and ammonium chloride (NH4Cl) were tested as nitrogen sources for bioethanol fermentation from date juice. Calcium chloride (CaCl2) and calcium carbonate (CaCO3) were evaluated as calcium sources for the same purpose mentioned above. The results showed that both calcium and nitrogen sources improved ethanol production efficiencies. The addition of calcium sources such as CaCl2 at 0.4 g/L resulted in maximum ethanol concentration (41.5 ± 0.85 g/L) and the highest productivity of 0.511 g/L/h. Thus, an increase of 31.3% compared to the control sample was acquired. Ammonium chloride was found to be the best nitrogen supplement among them. Indeed, supplementing the fermentation medium with 1 g/L NH4Cl gave an optimal ethanol concentration and productivity, reaching more than 65 g/L and 0.83 g/L/h, respectively. This is an increase of 106.6%. The functional group of ethanol (C2H5OH) for all the elaborated samples was confirmed by Fourier-transform infrared spectroscopy (FTIR) and NMR analyses. Moreover, the results confirmed the high quality and purity of the bioethanol products. Thus, the “Khodhari” date variety of low market value is a privileged substrate for industrial bioethanol production. For this reason, a proposed flow diagram of a designed plant for bioethanol industrialization is provided and detailed.

Soliman; Mahmoud Elsayed; Mahmoud Elsayed; Ramadan Hassany;This paper mainly introduces the potential of methane yield from co-digestion of primary sludge (PS) and the proposed new waste materials of sugarcane leaves (SL) and Corchorus stalks (CS) in Egypt. This paper includes three parts. In the first part, anaerobic co-digestion of PS, SL, and CS at different carbon-to-nitrogen (C/N) ratios was studied to determine the best C/N ratio. The results indicated that the maximum cumulative methane yields (CMYs) were observed at a C/N ratio of 18, which was associated with the highest volatile solid (VS) removal rate (74.41%). In the second part, the effect of using two types of inoculum (fresh cow manure (CM) and rumen content from slaughterhouses (RS)) on increasing the production of methane was investigated. Clearly, using CM as inoculum showed a superiority of the production of methane from co-digestion of PS, SL, and CS. The maximum CMYs were observed using the CM as inoculum from co-digestion of PS, SL, and CS. It was higher about 1.26 times more CMY using RS as inoculum. In the third part, the possibility of enhancing biogas yields from semi-continuous co-digestion of PS, SL, and CS using different organic loading rates (OLR) of 0.5, 1.0, and 2.0 was conducted. The highest biogas production rate was observed at an OLR of 1.0 gVS/(Lreactor.d) that coincided with the optimum VS removal rate. Statistical analysis of the results was conducted using analysis of variance (ANOVA) test, and the C/N ratio of 18 is statistically the best enhanced ratio. Overall, the feasibility of maximizing the methane productivity considering the anaerobic co-digestion of PS, SL, and CS under the optimal operating conditions and configuration was proved.

The influence of densification parameters on the quality properties of rice straw pellets was the main focus of this study. The conditioning factors analyzed were: moisture content of the feeding material (12%, 15% and 17%), starch as an additive (0%, 1% and 2%), operating temperature (below and over 50 °C), and the influence of three flat dies with different diameter/compression length (6/20, 6/24 and 8/32 mm/mm) on the pellet properties (durability, hardness, moisture content, dimension, and single and bulk densities). The quality of the pellets was evaluated in view of current standards. The results showed that the studied feeding and operating conditions had significant effects on the pellet properties, especially durability and bulk density, which are the most important parameters for pellet quality. All dimensions, most bulk densities, and few durability values of the produced pellets achieved the standard limits.
