The presence of light and laser beam has been studied at time 40 minutes. There are chemical reactions or chemical bonds that may form between the metal ions of medicines such as ibuprofen, folic acid, librex, ranitidine, albendazole and the iron drug, except for Ca 2+ and Ni 2+ because they have the same λ max, and, the pigments found in carrots, red cabbage, beets, turmeric, and maringa , sage, excluding Ca 2+ and Ni 2+ due to having the same λ max, beet, folic acid, iporphine, and, turmeric had the most changes with metal ions, Cu, Ca, Ag, Ni, Fe, Cr, Cd, Pb, Zn and Mn ions after inducing the laser beam. The Ca 2+, and Ni 2+ ions are the most stable ions with all drugs, and pigments extracted from natural products than the rest of the other ions. Previous studies focused on studying the effect of the laser beam on chemical compounds, both separately. In this study, they focused on the effect of the laser beam on medicines and natural dyes, as well as what they may contain of heavy metals or impurities and the chemical changes that occur with them.</p> 2022-02-10T00:00:00+00:00 Copyright (c) 2022 Journal of Pure & Applied Sciences http://sebhau.edu.ly/journal/index.php/jopas/article/view/1611 ICP-OES Analysis of some Nonessential Trace Elements in Hen's Eggs 2021-12-29T20:07:02+00:00 Adel Saeed adel_saeed73@yahoo.com Alkhader S. K. Mohammed alkhadernu2013@gmail.com Mokhtar S.S. Al-Salimi mokhtarsalim93@gmail.com <p>Eight trace elements (Al, V, Ni, As, Ba, Cd, Pb, and Hg) were quantitatively studies in three kinds of hen egg samples (home, street, and market hen eggs) collected from different regions in Aden city-Yemen including Al-Buraiqeh, Al-Hiswah, Khormaksar, and Shaikh Othman. Samples were wet digested and quantitatively analyzed by the Inductively Coupled Plasma-Optical Emission Spectrometer (ICP-OES) technique. Neglecting not detected values (ND), the range concentrations (in ppm units) of elements in hen’s eggs were in the range 0.407-7.414 for Al, 0.116-0.645 for V, 0.320-3.130 for Ni, 14.35-21.21 for As, 0.180-4.700 for Cd, 1.372-4.054 for Ba, and 12.078-15.14 for Pb. Since Yemen country does not screen the explored elements in this foodstuff, the recent work was done by comparing the results with other values reported in the literature and international standards. The mean concentrations of some studied elements such as arsenic, cadmium, and lead in some samples were exceeded the acceptable limits as detailed by presented international specifications and standards. The systematic national testing of hen's eggs production and the quality of environment and hen's feeds should be considered to protect public health.</p> 2022-02-21T00:00:00+00:00 Copyright (c) 2022 Journal of Pure & Applied Sciences http://sebhau.edu.ly/journal/index.php/jopas/article/view/1636 Accounting disclosure of green bonds as a tool for achieving sustainable development 2021-12-12T21:04:46+00:00 Eyad Ali Belhaj eyadbelhaj7@gmail.com <p>The accounting disclosure about the elements of sustainable development in general has received great attention from academic researchers, with the increasing interest in the dimensions of sustainable development SD. Previous literature, whether international or local, provided valuable insights into the significant role that accounting disclosure plays on economic, social, and environmental performance in achieving the Sustainable Development Goals (SDGs), but the accounting disclosure of green bonds has been neglected in research, and considering that green bonds are One of the modern practices of sustainable development, the current study responded to this research gap, as it aims to identify the role played by the accounting disclosure of green bonds in achieving sustainable development. The study used the integration of the inductive method, the deductive method, the historical method, and the descriptive method. The basic data were collected by means of a questionnaire specially developed for the purpose of the study. After analyzing the statistical data for (24) responses collected from accountants working at Al Yaqin Bank, the results showed a positive trend about the role played by the accounting disclosure of green bonds in achieving sustainable development. The accounting disclosure of green bonds has a positive role in improving the bank’s financing policy to support sustainable development, and assisting it in deciding the continuity of financing to support environmental projects, and it also achieves the bank’s profitability and contributes to improving its performance. The study extracted a proposed model that enables banks in general to make more effective decisions about issuing green bonds with the aim of serving the environment and the sustainable development. This model was based on the knowledge of the issuer of green bonds on four basic factors that must be made available to the beneficiary organization (the environmental orientation of the organization, its previous activities in supporting of the environment, its future plans, and its study for the employment of green finance).</p> 2022-04-12T00:00:00+00:00 Copyright (c) 2022 Journal of Pure & Applied Sciences http://sebhau.edu.ly/journal/index.php/jopas/article/view/1374 Morphological feature of Pelagia noctiluca (Forskål, 1775) (Cnidaria: Scyphozoa) in western Libyan coast, Tripoli 2021-10-25T02:43:51+00:00 Najla Abushaala abushaalan@yahoo.com Abdulfattah Elfituri elfituri74@egmail.com Abdullah Ben Abdullah none@none.com Hanan Shtewi marine_hananfish@yahoo.com <p>The Jellyfish cnidarians are important consumers of zooplankton in the Mediterranean Sea previously known.

The samples were collected from the Tripoli coast of Libya in September 2018 by scoop net. The number of samples was 31 individuals, collected to study the morphological structure measurements and wet weight. The results of the morphological structure showed the diameter of medusa 2.3 - 13.4cm, while the total length was 4.5 - 17cm, and the length of four oral arms was 2.4 - 12.9cm, the length of eight tentacles was 1.8 - 15cm and wet weight was 2.0 -73g. Based on morphological features and classification, the species was identified as Pelagia noctiluca (Forskål, 1775), but the differences between individuals in medusa size and wet weight indicate refers to different ages. So, this species is considered the first appearance on the Libyan coast.</p> 2022-02-21T00:00:00+00:00 Copyright (c) 2022 Journal of Pure & Applied Sciences http://sebhau.edu.ly/journal/index.php/jopas/article/view/1578 Application of Shannon and Simpson Diversity Index to Study Plant biodiversity on Coastal Rocky Ridges Habitats with Reference to Census Data in the Ras El-Hekma and Omayed Area on the Western Coastal Region of Egypt 2021-12-04T21:50:40+00:00 omar sharashy osharash@yahoo.co.uk <p>Biodiversity is a word recently introduced by experts in field of biology, and it is important for ecosystem health and productivity, biodiversity is one of the primary interests of ecologists, and the widely used diversity indices are Shannon’s and Simpson’s index. <br>This study aims to characterize the plant communities and to identify and compare the plant species diversity in the Ras El-Hekma area and Omayed protectorate. The results of the application of the indices of plant biodiversity in both the Ras El-Hekma area and the Omayed protectorate showed that the value of the Shannon index ( H' ) 2.058 and 2. 322, the value of the Simpson index ( D ) 0.85 and 0.92, the value of the Evenness index ( E ) 0.89 and 0.96, the value of Effective Number of Species ( ENSSh , ENSSi ) 6.66, 7.83 and 12.5, 10.19 respectively. The results demonstrated the highest values were recorded in the community of Omayed protectorate compared with the Ras El-Hekma area. The results also revealed that ( H' ) in the two communities 2 ≥ H' &lt; 3. According to the criteria of diversity index, they were moderate diversity. As for the Evenness index (E), 0.75 &gt;E ≤ 1. According to the categorized of the Evenness index, both are stable community.<br>Through the results, diversity indices indicate that there is a more diverse community in the Omayed protectorate compared with the Ras El-Hekma area. The reason may be due to the individuals in Omayed was more evenly distributed among the species than the individuals in Ras El-Hekma. Based on the interpretation of the criteria and categories of Shannon, Simpson, Evenness and Effective Number of Species indices, this meant that the Omayed had high environmental wellness and biodiversity level. Both indices are more reflective in nature and can predict the ecosystem health. Therefore, it may be good to have one of these biodiversity indices to be used for plant communities to understand the ecosystem healthiness in the habitats.</p> 2022-02-14T00:00:00+00:00 Copyright (c) 2022 Journal of Pure & Applied Sciences http://sebhau.edu.ly/journal/index.php/jopas/article/view/1702 UV-Vis Spectroscopic Study on a New Synthesized 4-Hydroxy-N-[(E)-(2-hydroxyphenyl)methylidene]benzohydrazide as Calorimetric Reagent For Mg2+ Ions 2022-02-09T21:12:14+00:00 Abdassalam A. A. Tameem salamtameem@yahoo.com Abdussalam S. Mohamed salam_salhin@yahoo.com <p>This study is concerned about the study of the chromogenic properties of hydrazone&nbsp;compound, i.e. 4-hydroxy-N-[(E)-(2-hydroxyphenyl)-methylidene]benzo-hydrazide towards magnesium ion recognition. The hydrazone compound was synthesized and characterized by FT-IR and NMR spectroscopy. The complexation ability of the studied ligand towards Mg<sup>2+</sup> was investigated using UV-Vis spectroscopy. Experimental parameters that affect the ligand-metal ion complexation such as effect of solvent, standing time, metal concentration and ligand concentration were investigated. Results show that HNHMB is preferentially to bind with Mg<sup>2+</sup> in ethanol. The addition of Mg<sup>2+</sup> to the ligand in ethanol gives rise to a large hyerchromic shift resulting in a colour darkness. From the linear regression analysis, Beer’s law was obeyed in at least 0.1–1.4× 10<sup>-4 </sup>M.

BenMahmoud ziadtaher@yahoo.com <p>Estimation This study was conducted in the laboratories of the Faculty of Agriculture at Misurata University. A total of 120 fresh eggs were collected from laying hens of commercial hybrids Hy-Line With36 strain. Then, samples were divided into two groups, The first group (WN) included 60 eggs from non-molting laying hens aged 16 months, and the second group (WM) included 60 eggs from Force-molted laying hens aged 10 months in the second cycle. The eggs were numbered and the external quality was estimated by weighing each egg, egg shape index (longitudinal and transverse axis), shell thickness, internal quality estimation by the thick albumen height, yolk index, and yolk color estimation. The results illustrated that there were significant differences in the egg weight and egg shape index of forced non-molting laying hens at the level of significance (P&gt;0.05). There was a direct relationship between the egg’s weight, the shell’s thickness, and the age of the hen, as well as the presence of a direct relationship between the height of the thick albumen height to estimate the Haugh unit with both the weight and the shape index of the egg. The compulsively Force-molted was significantly better than the non-molting laying hens, and the yolk index was suitable for the specifications of the standard extra fresh egg for the Force-molted and non-molting laying hens. There were no significant differences between the colors of the yolk in the Force-molted and non-molting laying hens due to the similarity of feeding.</p> 2022-03-03T00:00:00+00:00 Copyright (c) 2022 Journal of Pure & Applied Sciences http://sebhau.edu.ly/journal/index.php/jopas/article/view/1610 Studying the Causality Relationship between Inflation and Money Supply in the Libyan Economy Using Tod -Yamamomoto's Methodology 2021-12-05T21:26:32+00:00 Abdulhakam Alderdeer abd.alderdeer@sebhau.edu.ly Abdulbasit O.
