The number of individuals attempting to lose weight has decreased over the last 10 years. The initial step in tackling this issue involves the adoption of a healthy lifestyle. This research endeavor is designed to explore the influence of specific dietary components on the biochemical characteristics of obese rats. In this study, 36 Wister strain rats were subjected to different dietary conditions, with half of them being fed a high-fat diet while residing in well-lit environments, and the other half in dark conditions. Before sacrifice, the rats underwent a 12-hour fast, followed by the analysis of their blood and serum to assess various biochemical parameters. This study's findings imply that enriching the diet with hulled sunflower seed powder and wheat germ, along with vitamin D supplementation, led to increased vitamin D levels in the rats. Furthermore, the analysis revealed rats' lipid profiles improved. Moreover, the rats exposed to sunlight exhibited enhanced levels of vitamin D and improved hematological parameters when compared to those housed in dark conditions. Additionally, the sensory assessment of the food products containing sunflower seeds and wheat germ showed that the panelists were satisfied with the product quality. In summary, the study's results suggest that incorporating hulled sunflower seeds powder and wheat germ into the diet may contribute to the reduction and management of obesity.","PeriodicalId":7560,"journal":{"name":"Alexandria Science Exchange Journal","volume":" 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139141290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research found that the average number of chicks in the semi-closed system was about 9 chicks per square meter, while the average number of chicks in the semi-closed system was about 15 chicks per square meter, which demonstrates the high density in this system. It was also shown that the percentage of dead birds at the end of the cycle in the semi-closed system amounted to about 6% of the total chicks, while the percentage of dead ones at the end of the cycle in the average semi-closed system was about 4% of the total chicks, which shows the low percentage of dead ones in the average semi-closed system, and it became clear that the average amount of feed consumed In the semi-closed system, it was about 4.8 kg per chick, while the average amount of feed consumed in the average semi-closed system was about 4.1 kg per chick. The feed conversion efficiency in the semi-closed system was about 60%, while the feed conversion efficiency in the system was about 4.1 kg per chick. the semi-closed system rate is about 74%, which shows the high rate of food conversion, which provides large amounts of feed, which is a major problem these days in terms of their availability and prices. It was also shown that the total costs in the semi-closed system amounted to about 55 pounds per chick, while the costs amounted to the average total revenue in the semi-closed system was about 47.5 pounds per chick. The total revenues in the semi-closed system amounted to about 60 pounds per chick, while the total revenues in the average semi-closed system amounted to about 69.2 pounds per chick. Studying the difference between the two systems using formal variables shows an increase and superiority of the semi-closed system modified due to the closed system in the density of birds, the percentage of vitality, the average weight of the bird, the rate of production efficiency, and total revenues in pounds, and a decrease in it in each of the total variable costs in pounds, the total costs in pounds, and the amount of feed User for each bird. It was also shown from the total output function of the modified semi-closed system that the most important production elements that have a significant impact on the total output of one cycle of chicken farms in broiler houses is the amount of feed provided throughout the production cycle, whereas in the semi-closed system it was the amount of feed provided throughout the production cycle and bird density. The cost elasticity for the modified semi-closed system was 0.87, while for the semi-closed system it was 0.99.","PeriodicalId":7560,"journal":{"name":"Alexandria Science Exchange Journal","volume":" 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139141844","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, using highly nutritious, environmentally friendly fertilizers that are also compatible with the soil and environment is imperative. The application of fertilizers that give macro-and micronutrients to fruit trees is one of the key components of biofertilizer and nitrogen slow release fertilizers in agriculture. A two-year trial was conducted during the 2021 and 2022 seasons in Keitt mango trees orchard about five years old grown in sandy soil under a drip irrigation system from a well at a private orchard, in New Valley Governorate, Egypt. The main objective of this work is to study the effect of three rates of Nitrobein biofertilizer (0.0, 200, and 400 g/tree) and four rates of urea-formaldehyde fertilizer (0.0, 500, 750, and 1000 g/tree) on vegetative growth parameters, yield and fruit quality of Keitt mango trees. Briefly, Nitrobein and urea-formaldehyde treatments enhanced all studied growth, yield, and fruit quality traits. Nitrobein biofertilizer at 400 g/tree combined with urea-formaldehyde fertilizer at 1000 g/tree treatment proved to be the most efficient treatment in this respect.","PeriodicalId":7560,"journal":{"name":"Alexandria Science Exchange Journal","volume":" 48","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139137327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the primary objective of this research was to investigate the impact of two organophosphates (profenofos and chlorpyrifos), a carbamate (methomyl), and two pyrethroids (lambda-cyhalothrin and deltamethrin) on the viability and virulence of three strains of EPNs: Heterorhabditis sp. NEM 08, Heterorhabditis sp. NEM 15, and Heterorhabditis bacteriophora HP88. This investigation involved assessing their action on viability and infectivity toward the last instar larvae of Galleria mellonella upon exposure to recommended field rates for varying durations: 6 hours, 24 hours, and 48 hours. The results concerning EPN viability revealed that profenofos caused the most significant reduction in EPN viability, ranging from 44.9% to 65.9% after 48 hours of exposure. Additionally, the EPN strains exhibited varying levels of tolerance. Profenofos also had the highest adverse impact on infectivity, resulting in reductions ranging from 65.9% to 82.2% after 48 hours of exposure. Chlorpyrifos followed, which causing reductions in infectivity ranging from 25% to 55.6% after 48 hours of exposure. In contrast, Lambda-cyhalothrin had the least adverse effect on EPN viability and infectivity. Furthermore, it was observed that prolonged exposure time intensified the adverse effects on EPN viability and infectivity. These findings provide valuable insights for the integrated use of these neurotoxic insecticides with EPNs in insect control programs, helping in the selection of the most tolerant EPN strains for this purpose.","PeriodicalId":7560,"journal":{"name":"Alexandria Science Exchange Journal","volume":" 24","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139139253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hulled barley grain variety Giza 134 was cleaning and roasting at about 200 °C for 35,45 and 55 minutes and compared to a sample of Brazilian coffee. The sensory evaluation results, of roasted barley coffee drink at a temperature of 200 °C for a period of 35,45 and 55 minutes, and compared to the Brazilian coffee drink, showed that roasted barley coffee drink at 200 °C for 55 minutes received the highest scores compared to both roasted barley coffee drink at 200°C for 45 and 35 minutes, and was very near to Brazilian coffee drink. Also, color evaluation was performed for each sample of roasted barley and that of the Brazilian coffee sample. The percentages of protein, fat and ash in hulled roasted barley grains were lower than that of the Brazilian coffee, as these percentages reached 13.20%, 3.84%, and 3.33% in hulled roasted barley grains, while those percentages in Brazilian coffee reached 17.54%, 18.23% and 4.31%, respectively. The moisture, total carbohydrate and starch contents of hulled roasted barley grains were higher than those found in Brazilian coffee. The percentage of crude and dietary fiber decreased in roasted barley grains compared to that in Brazilian coffee, Also, total phenols and antioxidant activity decreased in hulled roasted barley grains compared to Brazilian coffee, reaching 166.22 mg gallic acid/100g and 52.18% in hulled roasted barley grains, while they reached to 1577 mg gallic acid/100g and 90.20% in the Brazilian coffee. The caffeine content of hulled roasted barley grains was zero per cent, while its percentage in Brazilian coffee was 0.87%. The results showed that the mineral contents (magnesium, calcium, iron, potassium and sodium) were higher in the Brazilian coffee (160.67, 57.30, 21.30, 2200 and 93.33 mg / 100 g) compared to hulled roasted barley grains (149.69, 32.97, 15.03, 700 and 76.67 mg / 100 g), respectively. On the other hand, the global production of coffee is about 6 million tons, produced in 9 countries, and Egypt imports about 137 thousand tons, representing about 2.30% of that production, with a cash value estimated at 2.10 billion pounds. It can be provided through a barley coffee drink, with complete replacement, while it can be reduced to about 1.04 billion pounds in the case of 50% replacement, and about 0.50 billion pounds in the case of 25% replacement only. So, consuming barley coffee instead of natural coffee beans in different proportions can lead to the provision of hard currency.","PeriodicalId":7560,"journal":{"name":"Alexandria Science Exchange Journal","volume":" 24","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138617125","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two experiments were conducted during 2021 and 2022 seasons, at El-hager area, Abou El-matameer, Al-Behira governorate. Side effects of the tested insecticides were also observed on the two predators lady beetle Coccinella septumpunctata Linnaeus and aphid lion Chrysoperla carnea Stephens. Imidacloprid significantly (P<0.05) achieved the highest initial and residual activity against aphid and whitefly in both seasons. The initial and residual reduction percentages of aphid were 94.5 and 98.9% in 2021 and 91.5 and 96.5% in 2022 as well as reduction percentages of whitefly was 85.7 and 92.4% in 2021 and 86.8 and 93.1% in 2022. Novaluron, buprofezin, pyriproxyfen and azadirachtin showed a moderate activity against whitefly and aphid in both seasons while orange and jojoba oils revealed the least reduction percentages. However, orange and jojoba oils have the least side effects on the aphid lion where the residual reduction percentages were 5.3 and 6.4% in 2021 and 6.4 and 7.3% in 2022.
