Carbon capture and storage (CCS) is promoted a promising decarbonization strategy. It is argued to be a potential solution for Egypt’s greenhouse gas emissions which have substantially grown over the past three decades. A widely recognized method of CCS is biological storage via microalgal cultivation. However, most CCS applications in the oil sector are geologic storage and there is no single biological storage project in Egypt. Additionally, there is a severe lack of research on microalgal applications for CO2 storage in Egypt. The study examined how technically, and economically feasible microalgae is in the sequestration of CO2 emissions, given the local context of oilfields in Egypt. That is why this research aimed to build a case study for a pure source of CO 2 emitted from a gas-sweetening plant in an oil company in the western desert of Egypt. To do so, this paper performed a laboratory experiment to examine the tolerability of two microalgal species for being exposed to a CO2 source. Based on the results of this experiment, a technical model was proposed to select the required machinery and infrastructure. Finally, it proposed a financial model of the capital and operating costs, loan repayment schedule, and net present value with sensitivity analysis. The findings showed that selling biomass as a final product was uneconomic as it generated negative IRR and NPV. More interestingly, trading carbon credits in the Egyptian voluntary carbon market can help finance the project, with the least acceptable price of 9.7 US$/ton of CO2. The originality of this research comes from its multidisciplinary approach of adopting phycology science in the oil industry and its generalizability to similar CO2 sources in locations with no restrictions on land availability.
Nanotechnology is defined as the manipulation and control of matter at the nanoscale using scientific knowledge from various industrial and biomedical applications. The nanoparticle generally refers to the individual molecules that make up the bulk of the nanomaterial. Nanoparticles are particles with a size of one to 100 nanometers (nm) and made up of three layers since they are complex molecules. This study was carried out to prepare Copper Oxide nanoparticles (CuO NPs) using the green synthesis method which is an environmentally friendly technique without using hazardous chemicals. Hazardous chemical substances lead to pollution of water which causes environmental contamination, so we used CuO NPs that were synthesized by using green method to purify the wastewater containing lead ion. Hence, the extracts of Spinacia oleracea were used as reducing agent. The synthesized CuO NPs nanoparticles were characterized using scanning electron microscopy (SEM), Energy Dispersive X-ray Analysis (EDX), Ultraviolet–Visible spectroscopy (UV–Vis), Fourier transform infrared spectrometry (FTIR). The two parameters of experiments, the metal ion concentration and pH were studied for the removal of Pb (II) from wastewater using the CuO NPs as nanosorbent. The synthesizing of CuO NPs was successful, the color change of the mixture of copper sulphate and spinach extract from light green to dark green indicates the succession of the synthesizing CuO NPs. The EDX and UV-Vis spectroscopy also indicated the succession of synthesizing of CuO NPs. The optimum removal efficiency of Pb (II) was found 78% and 85% for pH 7.01 and concentration of 0.002M, respectively. These factors showed that CuO NPs are good nanosorbents to purify wastewater contaminated with lead ions.
Rabbits can get intestinal illnesses, particularly after they've been weaned and switched from milk to solid food. Propolis (PR) is a mixture of proteins, carbohydrates and phenolic compounds that can increase the level of serum immunoglobulin, improve the antioxidant state of the animals and lessen the severity of clinical symptoms and death. So this study was designed to evaluate the effect of using (PR) on productive performance, cecum microbial activity of postweaning growing male rabbits. Twenty New Zealand White (NZW) male rabbits, 5 weeks old were randomly divided into two equal groups, with 695.75± 10.01 g BW. In the 1st group, rabbits were fed without any supplementation and considered as the control group. While, those in the 2 group were orally given (PR) at 500 mg/kg BW 3days /week for 10 weeks. Results revealed that nd growing rabbits treated with (PR) show a decrease in pH value and E. coli count as compared with the control group.in addition, using (PR) causing significantly increased in plasma total protein, albumin and globulin concentrations in treated than the control group. Conclusively, from the obtained results it could be concluded that the supplementation of(PR) had positive effects on rabbit’s performance as well as, cecal microbial activity of growing rabbits.
Mango seed kernel, apricot seed kernel, papaya seed and roselle seeds are the most important wastes remaining after the processing of fruits. Due to the shortage of edible oils particularly in developing countries, it has become necessary to search for new sources of oils. Therefore, the aim of this study was to evaluate the possibility of utilization these wastes as untraditional sources of edible oils. The results showed that all seeds samples had high amounts of oils and considered to be a good source of crude oils. Physicochemical properties of the oils extracted were iodine value, 54.25-112.30 g I2 /100 g oil; saponification value, 189.36-195.45 mg of KOH/g of oil; acid value, 0.88 - 2.56 mg of KOH/g of oil, free fatty acid, 0.83 - 2.29 g/100 g of oil, and peroxide value 1.29-2.89 meq of O2/kg of oil. Oil samples had high amounts of unsaturated fatty acids with oleic and linoleic acids being the major ones. The major fatty acids in mango seed kernel oil were stearic and palmitic acids which recorded 49.33 and 8.06%, respectively. It is worthy to mention that the percentage of unsaturated fatty acids in apricot seed oil was the highest (93.59%), followed by papaya seed oil (79.81%) and roselle seed oil (73.19%), respectively, which reflect the nutritional importance of these oils.
The efficacy of Metformin in managing type 2 diabetes varies widely due to genetic diversity, influencing pharmacogenomic responses. Recent studies, employing Genome-wide association research (GWAS), have identified genetic variants associated with Metformin response, revealing pathways like AMPactivated protein kinase (AMPK) and Ataxia Telangiectasia Mutated (ATM) involved in its mechanisms of action. Genetic variations in transporter genes like OCT1 and MATE2 affect Metformin absorption and glucose regulation. Collaboration through multicohort meta-analyses validates these findings, considering ethnicity and environmental influences. Despite these advancements, research on genetic determinants of Metformin response in Middle Eastern populations is limited. Studies from Lebanon, Egypt, Jordan, and Saudi Arabia highlight associations between genetic variations and Metformin response in type 2 diabetes. The Inclusion of diverse populations in genomic databases like the Genome Aggregation Database (gnomAD) and tools like the Ensembl genome browser enhances understanding of genetic diversity for personalized medicine. Greater inclusivity in genetic studies is crucial to improve research generalizability and advance personalized medicine in diverse populations, addressing disparities in genomic research representation. This underscores the need for a multifaceted approach to personalized diabetes management, integrating pharmacogenomic insights from diverse populations.
