Abstract:Abstract\nThe activation of the flexible work regulation on the ground in the Hashemite Kingdom \nof Jordan, with its positive advantages for both workers and employers, which cannot be \nunderestimated during the Corona pandemic crisis, leads to the continuity and \npermanence of work and thus reduces the negative economic effects caused by the\npandemic.\nEspecially remote work which is a form of flexible work that reduces work-related stress, \ntension, and the need to use transportation. This leads to easing traffic, and reducing \ntransportation expenses for workers, as a result it gives employees greater freedom to \nwork independently which improves their job performance. However, remote work as \none of the most prevalent forms of flexible work, during the Corona pandemic, has many \ndisadvantages, not only from a practical point of view, but also from a psychological and \nsocial point of view for employees, as it results in the worker not being able to separate \nbetween his/her professional life and family life which makes work affect family duties \nand vice versa..\nThis study was divided into two chapters, the first addressed the nature of the flexible \nwork contract, while the second investigated the flexible work regulation during the \nCorona pandemic crisis. As a result, the study reached important findings, the most \nimportant of which is that the flexible work regulation No. (22) was issued in 2017, but it \nwas activated and implemented on the ground during the Corona pandemic after the \ndeclaration of a state of emergency in the Kingdom, through the Defense Order No. (6)of 2020, which involved some restrictions and conditions and caused interruption of \nwork based on some of its provisions, thus giving employers and workers greater\n\naudacity to work with it, in order to ensure the sustainability of work during the Corona\npandemic crisis. Based on the findings of the study, a set of recommendations was\npresented, the most important of which is activating the communication between the\nMinistry of Labor and the Social Security Corporation to study the impact of the \nprovisions of the flexible work regulation on the right of employees to social security so \nthat the hours, days and wages are calculated in a way that does not affect their rights or \ndeny them social security.
Abstract:halepensis Mill freshly collected in spring, 2018 in the region of Ouled Brahim (Saïda, Algeria), an anatomical cut watch existences an epidermic coat to lignify covered by cuticle , cells stomatics around cortex, resinous canals at the level of the mesophyll followed by tissues of transfusion and tissues criblo-vascular. The essential oil of needles of Pinus halepensis Mill. obtained by hydrodistillation of a yield 0,63 % and includes 33 components chemical. The members of the majority party are ß-myrcène (18,45 %) is monoterpenique hydrocarbon, α - pinene (14,80 %) is a bicyclique monoterpene, Garanyl linalool (09,10 % is a terpénique alcohol) it brings a floral and fresh touch, These three compounds establish more than half total chemical composition of essential oil. The chemical composition is also variable quantitatively and qualitatively according to the place of harvest and during the development of the plant.We hope that this preliminary work will generate enough interest to make people aware and protect the gene pool.
Abstract:Drinking water is a possible source of humans’ illness when it contains chemicals and\nmicroorganisms especially from anthropogenic activities. The purpose of this study was to\nevaluate the quality of the water in the Cheffia dam. Three sampling stations were selected over\nthree months December, February and April 2019 to determine the physicochemical and\nbacteriological parameters of the water. Some physicochemical parameters and heavy metal\nconcentrations were analyzed in water samples (T, pH, EC, DO, Salinity, Turbidity, Cl–\n, Ca2+\n,\nMg2+,NO2\n–\n, NO3\n–\n,NH4\n+\n, PO4\n3–\nand Fe2+). The samples taken for the bacteriological study was\nhave focused on the research and enumeration of total germs, faecal coliforms and faecal\nstreptococci.\nThe results indicated that most of the physicochemical parameters of the Cheffia dam were\nwithin or at the permissible limit of Algerian standards and WHO for drinking and irrigation\nwater. The bacteriological results obtained showed the presence of significant levels of total\ncoliforms (≥50 CFU/100ml), faecal coliforms (with an average ≥55 CFU/100ml) and faecal\nstreptococci (average ≥40 CFU/100ml). The high load of these germs during the study period\nmay be due to runoff and unhygienic behavior observed in the study area. Our results show that\nwater from the depth station is highly polluted because it has high levels of most\nphysicochemical and bacteriological parameters compared to other stations.
Abstract:The good quality of source water for the consumption of living organisms and especially that of humans is a very important element for public health protection. To appreciate the quality of these waters, a physicochemical and bacteriological control was carried out on two water sources in the region of Souarekh in the wilaya of El Tarf (Ain Siglèb and Ain Siporex). \n The objective of our work is to evaluate the quality of these waters, to measure the various physical parameters (T°, pH, EC, Salinity, TDS and Turbidity), chemical (CAT, Ca+2, Mg+2, Na+, K+, Cl- and Cl2) and pollution indicators (PO4-3, NH4+, NO3-, NO2-, BOD5 and COD). For the bacteriological analyses, we determined the presence or absence of total and faecal coliforms, sulfuto-reducing clostridia, faecal streptococci, Salmonella, E. coli and Cholera Vibrio.\n The results indicated that most of the physico-chemical parameters of Ain Siglèb and Ain Siporex are situated within or at the margin compared to the admissible limits of the Algerian and WHO standards for drinking water and irrigation water. Microbiologically, the results showed that the water sources studied undergo significant contamination by total coliforms, faecal coliforms, streptococci and clostridium in Ain Siglèb compared to that of Ain Siporex. The latter should be given special attention due to extreme climate changes and increased pollution.
Abstract: Human being\'s massive exploitation of fossil energy has resulted in energy crisis, which restricts the development of society and the progress of science and technology. With the development of clean and renewable energy, such as solar energy and wind energy, this issue has received more and more concerns. Aerodynamic performance of 5-Blade Vertical Axis Wind Turbine with varying blade width was studied by 3-D CFD numerical simulation. In the numerical calculation, the FLUENT is used to perform the simulation of the flow property of the wind during turbine blade rotating process, at the same time a low speed flow is promised. The air is assumed as an incompressible fluid, with no heat transfer, etc. The results show that: the power of the wind turbine showed a peak with increase of blade width; The maximum power of the wind turbine appeared at the blade width of 0.8, and the blade rotation rate of 17rpm; The corresponding power value is 194.97W for 5-Blade Vertical Axis Wind Turbine at the blade width of 0.8, height of 1m and the blade rotation rate of 17rpm; and the wind energy utilization coefficient was 15.61%.
Abstract:Recently, an increasing number of works have been devoted to studies of the accumulation of heterocyclic aromatic amines in food products. Basically, such works are devoted to factors affecting the amount of formation of heterocyclic aromatic amines, as well as ways to reduce their amount. The purpose of this work was to conduct monitoring studies of products sold in fast food restaurants. The results showed that each of the selected restaurants had at least 1 product, during the heat treatment of which heterocyclic aromatic amines were formed, but at the same time the obtained values did not exceed 10 ng/g of the product. Also, in most samples, only one of the two analyzed analytes was detected. Thus, products sold in fast food restaurants can potentially pose risks to human health due to their heterocyclic aromatic amines content.
Abstract:Small and medium enterprises (SMEs) have been identified as catalysts for the economic growth in Nigeria as they are major sources of income generation and job creation and contribute immensely to the nation’s gross domestic product (GDP) as well as livelihood sustainability in the country. Despite what private investors and government have done and still doing in order to enhance the performance of the SMEs, most of them are still constrained by poor management skills and lack of modern technology, which may be as a result of inadequate financing leading to inadequate sales growth. The general objective of the study was to determine the effects of entrepreneurial financing dimensions on the sales growth of selected SMEs in Ogun State, Nigeria. The study adopted cross-sectional survey research design. The population comprised 1,794 owner/managers of SMEs. The sample size was 425. A validated questionnaire was administered for data collection. The Average Variance Extracted of the constructs ranged from 0.741 to 0.908. The response rate was 82.4%. Data were analysed using descriptive and inferential statistics and multiple regressions. Findings from the study revealed that eentrepreneurial financing dimensions (bank loans, government grant, venture capital, funds from family) had positive and significant effect on sales growth of SMEs in Ogun State (R = 0.601, Adj. R2 = 0.354, F (4, 345) = 48.764, p < 0.05). The study concluded that entrepreneurial financing dimensions play an important role in enhancing the performance of selected SMEs in Ogun State, Nigeria. Thus, this study recommended that the financial institutions should creatively craft and adopt the availability of cheaper funds that would spur the sales growth of SMEs with view to sustainability while enhancing economic growth.
Abstract:Price stickiness affects economic system broadly. This article focuses onduopoly innovation under sticky price with differential game theory approaches. Wefound that sticky price weakens firmsï¿½ market power and stimulates firmsï¿½ innovationunder both open-loop and closed-loop solution. Moreover, higher price stickinessyields more outputs and lower price. More interestingly, open-loop equilibriumstimulates innovation more than that of closed-loop. The policy implication is toencourage commitment price strategy.

Abstract:Forensic entomology is considered a branch of general entomology which was recently founded and ruled by the Entomology Society of America in the 1990s, followed by this ruling the society approval came to establish what is known today as the American Board of Forensic Entomology (ABFE) in 1996. \nIt can be also called forensic biology which is the field of science that depends on different kinds of insects as a fundamental base to reveal the mystery of a crime circumstances especially violence crimes in general and homicides in specific. As many insects start their life cycle when the death of a living creature occurs, criminology have used many ways to reveal the mystery of a crime facts and circumstances, but even with the great scientific evolution a medical examiner is still unable to estimate the exact precise time of death after the passage of 72 hours corpse decomposition, however by using forensic entomology the exact time of death can be precisely estimated. \nIt is for sure that forensic science depends on more than field of science and method to solve and reveal the mysteries of crimes, and for every case there is a way or more that can be more analytically accurate for an incident, and sometimes more than one method are used for the same crime to reveal the identity of a murderer or the time of death in a more positively accurate way. \nConsequently insects are used in forensic science in combination with other critical important fields of science in criminal investigation like criminological psychology, Toxicology, Forensic Identification, fingerprint, hair print and memory print identification, and most importantly the DNA profiling.
