The purpose of this research was to plan an approach to a project framework that integrated a model for sustainability and CSR, with the process groups of the Project Management Body of Knowledge (PMBOK®) standard, in its application to the training of a group of students in Project Design, Management, and Evaluation. The integration was justified by the scarce explicit references to sustainability and CSR found in traditional project management guidelines, norms, and standards. The new framework was used to structure a Sustainability Management Plan, which made it possible to incorporate sustainability criteria throughout the life cycle of the training project. The training proposal in Project Design, Management, and Evaluation was chosen, among several alternatives, by a multi-criteria selection process (fuzzy AHP) in the context of project scope management. The results reveal a great heterogeneity among the models and the lack of a base of key indicators in sustainability and CSR measurement tools as well as of explicit references to sustainability in project management standards. It is therefore necessary to develop a Sustainability Management Plan that can be introduced in the Project Management Plan and thus influence the strategic and operational guidelines of the Institution.

AbstractBackgroundThe Gaza Strip in Palestine is currently facing a serious electrical power deficit due to the local political situation. In addition, the main source of energy in Gaza Strip is traditional fossil fuel which is environmentally harmful. To ensure that electrical power in the Gaza Strip can be maintained continuously without any day-long power failures is a challenging task for decision-makers. The lack of reliable electrical power has motivated the inhabitants of the Gaza Strip to adopt an alternative source of energy which is reliable, sustainable, environmentally friendly and abundantly exists. Therefore, they decided to implement solar energy systems to power their houses in order to replace or to complement the traditional sources of energy. This has motivated the current study which aims to find out whether solar energy can be an alternative source of energy to the conventional energy for domestic use in the Gaza Strip to sustain inhabitants’ daily life. This has been tested by studying the readiness and attitudes of household people in the Gaza Strip to adopt solar energy in their homes. This work is a novel study in its contents. According to the authors’ knowledge, this is one of few studies considering this topic.MethodsTo understand the reasons for successful solar energy system adoption by individual households in Gaza, the authors have created an electronic questionnaire. The dependent variable is chosen to be the adoption of energy, and independent variables are the environmental benefit, the cost of adoption of solar energy, and the economic savings of solar energy measured. The electronic questionnaire consists of two parts: part one consists of personal questions; the second part consists of 22 items on a five-point Likert scale and the studied sample population consists of the 10% of the Al-Shifa Medical Complex employees (1819 employees). The electronic questionnaires were electronically circulated to the study sample. The data were then collected and analyzed using an SPSS program.ResultsThe authors found that only 19.5% of the studied sample population have installed solar energy systems on their houses. The results show that some factors, including the governorate in which employees are living, house ownership, total cost of energy/month, available space to install the solar panels, and the desire to share the cost with neighbors did not affect the decision to use solar energy. On the contrary, the type of house and the knowledge of renewable energy influenced the decision. Compared to previous studies, we also found that knowledge is an important factor in implementing renewable energy (Zakaria et al. in Earth Environ Sci 268:012105. https://doi.org/10.1088/1755-1315/268/1/012105, 2019, Szakály et al. in Energies 14:1–25. https://doi.org/10.3390/en14010022, 2021). Though our study did not reveal an impact of cost of installing the system on making the decision to adopt renewable energy (Assali et al. in Renew Energ 136:254–263. https://doi.org/10.1016/j.renene.2019.01.007, 2019), we will it regard it as an important factor.ConclusionThe adoption of solar energy in Gaza is limited. The kind of the house and the knowledge of renewable energy are imperative to increase utilization of solar energy by households in Gaza. Therefore, it is important to start a public information campaign on the advantages of solar energy through the universities by giving classes to all university students and/or by giving general talks for the public. To conquer the limiting factors, the public authority ought to consider the framework and support the neighborhood occupants.

Natural products including, traditional medicinal plants have emerged as a tempting alternative to conventional chemotherapeutic protocols of leukemia because of their minimum side effects and less documented drug resistance.Ethanol extracts were prepared from Thymus vulgaris L. and Origanum syriacum L. plants and investigated against the THP-1 leukemia cell line and freshly isolated peripheral blood mononuclear cells (PBMCs). The 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide (MTT) assay and the lactate dehydrogenase (LDH) assay were respectively used to determine the cellular viability and cytotoxicity in response to treatment with increasing extract concentrations.Both extracts exhibited a concentration dependent reduction in viability of the THP-1 cells (IC50 = 2.126 mg/mL for O. syriacum, and 0.1569 mg/mL for T. vulgaris). O. syriacum was more potent against the PBMCs (IC50 = 0.4247 mg/mL), while T. vulgaris was moderately selective (IC50 = 0.3345 mg/mL with PBMCs and SI = 2.1). Only in O. syriacum the reduction in cells viability was caused by cytotoxic effect against leukemic cells (LC50 = of 9.646 mg/mL).T. vulgaris and O. syriacum are both antileukemic in vitro. T. vulgaris represents a potential selective cytostatic and safe target for future anticancer agents' development. O. syriacum on the other hand is cytotoxic against the leukemia cell line THP-1.

Abstract This paper investigates the impacts of CO2 tax schemes on CO2 emissions, equity and macroeconomic indicators in Austria with the macroeconomic model DYNK[AUT]. Our scenarios focus on non-ETS CO2 emissions and comprise different tax rates and revenue recycling options (lower labor taxes, lower VAT and lump sum payments). The short-term comparative scenario analysis indicates that CO2 taxes without recycling lead to significant CO2 emission reductions at moderate economic costs. Equity impacts on households depend on the indicator used but can be regressive without recycling. Most recycling schemes can achieve a double dividend, i.e. emission reductions and increases in GDP. Lump sum payments are less efficient than reducing the VAT or labor taxes. Equity impacts are progressive with lump sum payments, rather proportional with lower VAT and regressive with lower labor taxes. A combination of recycling schemes and/or a restriction of lump sum payments to lower income households can minimize the trade-off between equity and efficiency. Our simulations suggest that well-designed CO2 tax schemes could be a crucial and socially acceptable element within a comprehensive policy package to achieve GHG emission targets for non-ETS sectors in Austria.

Abstract This work reports the drag coefficients (Cd) for three wind directions measured in low turbulence flow and in turbulent flow with characteristics of the atmospheric boundary layer wind, and the Strouhal numbers (St) of an approximately trapezoidal flanged section, used in the boom girder of a 100 m high port crane. These experimental results were obtained at the Boundary Layer Wind Tunnel of the Dept. Aeronautica at the Universidad Nacional de La Plata, in the range of Reynolds numbers between 30,000 and 180,000. The drag coefficients in the three studied directions showed a reduction for turbulent flow. Further measurements were carried out for the model with an inclination of 80° relative to the flow direction, the position of the crane boom when out of service, giving practically the same drag coefficients.

This paper focuses on retrieving plant leaf images based on different features that can be useful in the plant industry. Various images and their features can be used to identify the type of leaf and its disease. For this purpose, a well-organized computer-assisted plant image retrieval approach is required that can use a hybrid combination of the color and shape attributes of leaf images for plant disease identification and botanical gardening in the agriculture sector. In this research work, an innovative framework is proposed for the retrieval of leaf images that uses a hybrid combination of color and shape features to improve retrieval accuracy. For the color features, the Color Difference Histograms (CDH) descriptor is used while shape features are determined using the Saliency Structure Histogram (SSH) descriptor. To extract the various properties of leaves, Hue and Saturation Value (HSV) color space features and First Order Statistical Features (FOSF) features are computed in CDH and SSH descriptors, respectively. After that, the HSV and FOSF features of leaf images are concatenated. The concatenated features of database images are compared with the query image in terms of the Euclidean distance and a threshold value of Euclidean distance is taken for retrieval of images. The best results are obtained at the threshold value of 80% of the maximum Euclidean distance. The system’s effectiveness is also evaluated with different performance metrics like precision, recall, and F-measure, and their values come out to be respectively 1.00, 0.96, and 0.97, which is better than individual feature descriptors.
