Assessment of Weaknesses and Inadequacies in Libyan Laws and Legislation on the Protection of Vegetation

Abstract In recent decades, the countries around the world have made great efforts in environmental protection programmes, where they have worked to establish a variety of organizations and bodies to support those efforts, especially developing countries, including the issuance of several international treaties, conventions and protocols, accompanied by many legislations and laws on the protection, preservation and maintenance of the environment for future generations, particularly those laws and regulations which deter certain industrial activities which have been reunited and destroyed by vegetation and in the same way hundreds of regional and international seminars and conferences to preserve them. This study highlights the importance of Libya's laws and regulations on the conservation of vegetation and natural resources and the Inadequacies of those laws, which may render them incapable of achieving the objectives for which they have been set, and one of the most significant objectives is to be able to contribute as much as possible to the reduction pollution, as well as that the provisions of the Pun law. The study concluded that there is a clear deficiency in Libya's laws on the protection of vegetation and natural resources, particularly in the field of sanctions and the prevention of offenders and perpetrators of such crimes, including Law No. 15 of 2003 on the protection and improvement of the environment contained in articles (72-73-74) and some paragraphs of Law No. 6 of 1996 on the protection of agricultural land and Resolution No. 9 of 2012 on the protection of public land, In addition to some other Libyan regulations on the agricultural sector. At the end, the study aims to make some suggestions to jurisdictions on strengthening the criminal provisions of Libyan legislation related to those in bordering countries, for example, to provide compensation based on the degree of damage caused, redress for conventional and environmental damage, and the cost of restoring the status quo or restoring the environment.

Evaluation of Drinking Wall's Water Quality in Murzuq Basin Southwest of Libya

Abstract Groundwater is the most important water source in the study area due to its occurrence within the dry areas, therefore it became necessary to evaluate and study the quality of Murzuq basin water which located in the southern east of Libya. It is a one of the largest reservoirs in Libya, it covers 350.000 km2 containing 7700 km3 of freshwater, about 4100–13800 years old. This study investigated the quality of drinking water supplied from the Murzuq basin to the general drinking water network of Murzuq city and suburbs. A total of 10 sites were selected for water analysis. Chemical and physical parameters were determined and compared to the WHO and Libyan Standard. The results obtained from this study showed in terms of a difference in the concentrations of salts in drinking water, the pH values were between 5.50 - 7.73, while the concentration of Total dissolved salts TDS range between 54 - 1903 mg/L, the water sample of wall No. 7 exceeded the permissible limit within the specifications, the EC value is between 85 - 2970 μs/cm³, while the total hardness concentration was between 20 - 992 mg/L and there are samples of water No. 7 and No. 8 have exceeded the limits. while the calcium concentration was between 6 - 306 mg/L and the water sample No. 7 exceeded the limit, the concentration of magnesium ranged between 2 - 55 mg/L, As for the concentration of sodium, it was between 4 - 183 mg/L, and potassium was between 6 - 39 mg/L, while the concentration of chloride was between 10 - 344 mg/l where the water sample No. (8, 9) exceeded the permissible level according to specifications, and concentration values Bicarbonate ranged between 33 - 122 mg/L.

Optimization of Nonlinear Differential Equations for Defining One Leg Human Locomotion

This paper discusses how to optimize the Bidirectional of the central pattern generators (CPGs) to produce rhythmic patterns for human locomotion by using the enhancement Genetic Algorithm and pattern search function. It also shows how small changes in some CPG parameters in stable domain result in different walking gaits, optimizing bidirectional two CPGs in stable domain do not only enhance movement but also generate rhythmic patterns similar to the rhythmic patterns derived from real data without any input or sensory feedback.

Audit Team Characteristics, and External Environment Audit Factors: Effects on Audit Quality in Libya

Abstract: Purpose: The paper aims to analyse audit team characteristics that were perceived to be affected on audit quality. Specifically, it focuses principally on whether audit team characteristics, i.e., independence, continuous education and training, experience and professional conduct enhances audit quality. This study examines the moderating effect of the external environment audit i.e., professional bodies, laws and regulations, and recognized standards in the relationship between audit team characteristics and audit quality. Design/methodology/approach: Multiple regression analysis is applied to examine the association between variables of the study. A questionnaire survey was conducted of 251 external auditors, by personally administered questionnaire from Libyan the Association of Accountants and Auditors (LAAA) . Findings: the audit team characteristics have positively and significantly related to audit quality. As well as the regression analysis at dimension level shows positively and significantly related to audit quality. The findings also indicate that the external environment audit factors moderates the relationship between variables of study. Practical implications: The instrument presented will provide to measure audit quality in Libya, with a practical understanding in the area of audit quality. Moreover, researchers and practitioners from other may be able to use these models in future to measure audit quality. Originality/value: This is the first study examining the impact of external environmental factors on audit quality and the findings demonstrated its moderating effect on audit quality. Keywords: Audit team characteristics, External environment audit factors, Audit quality, Libya

Removal of Multi-heavy Metals from Simulated Wastewater using Hybrid Modified Carbonized Palm Shell and Rice Husk Adsorbents

It necessary to remove heavy metals from wastewater in order to comply with environmental regulations and for sake of human health and safety. The purposes of the present study was to prepare hybrid modified adsorbent from the carbonized palm shell and rice husk by physical treatment for the removal of 13 multi heavy metal component from simulated wastewater by single bed adsorption column. The Metals being studied are Cadmium, Chromium, Copper, Iron, Magnesium, Manganese, Lead, Lithium, Molybdenum, Nickel, Antimony, Vanadium and zinc. Six types of adsorbents were used for metal removal which are (100% BRH) adsorbent; (100% CPS) adsorbent , and four hybrids adsorbent prepared by mixing the blended rice husk and carbonized palm kernel shell with mixing ratios 20% , 40% , 60% , 80% wt Blended Rice Husk . The obtained results of the individual area under the graph analysis showed that cadmium, copper, lithium; vanadium elements were strongly adsorbed by hybrid adsorbents with achieved removal efficiency of 99.95%, 99.97%, 31.23%, and 89.58% with least area under the graph values of 3294.65, 2015.52, 118.231, and 115.18 respectively. As a conclusion, the mixing of blended rice husk and carbonized palm shell as hybrid adsorbent contributed to enhance the adsorption performance of cadmium, copper, lithium, vanadium, elements which demonstrated by less area under the graph values compared with pure carbonized palm shell and pure rice husk adsorbents.
