The purpose of this study was to see how non-antibiotic growth boosters such as Probiotic, Prebiotic, Synbiotic, and medicinal herbs (Mixture of Origanum majorana, Foeniculum vulgare, and Carum carvi in a 1:1:1 ratio) affected carcass yield, immune response, blood hematological, and biochemical parameters in broilers fed test diets with two dietary protein levels (normal and low). The research was conducted at Alexandria University, Poultry Research Center, Faculty of Agriculture. The trial lasted 42 days in total. A total of 500 one-day-old Cobb broiler chicks with similar average live body weight were assigned to one of ten treatment groups. Each treatment has five replicates with ten chicks each. Ten experimental diets were developed to be nearly is caloric and to provide all nutrients required for broiler growth throughout two stages of development: starter diets (1 - 21 days) and grower diets (22 - 42 days). Ten experimental diets were made up of five feed-additive programs and two amounts of crude protein (recommended or low, 85 percent of recommended) (control, probiotic, prebiotic, synbiotic and medicinal plants). Among the additives, synbiotic had a positive effect on the WBCs, RBCs, in general, especially the Fabricius bursa Under the conditions of the current study, synbiotic had a significant impact on hematological parameters, carcass yield, and immunological organs of broiler. Furthermore, more research is required to confirm the existing findings.

 The groundwater aquifers in Azintan, northwestern Libya suffer from an acute shortage of water. The groundwater was evaluated to determine its suitability for drinking and irrigation purposes from major two aquifers in north and south of Azintan area. This study carried out to assess the groundwater quality and to identify major affecting variables. Twelve samples from the two aquifers were collected. The two aquifers were collected and analyzed for total dissolved solid (TDS), electrical conductivity (EC), pH, Ca²⁺, Mg²⁺, Na⁺, K⁺, Cl^-, SO4^2-, CO3^2- and HCO3^-. The results show that, the groundwater in many places is dominated by higher concentrations of Cl^-, SO4^2- and HCO3^-. Two water types were recognized in this region are Cl-SO4- Na-Ca and Cl-SO4-Na. Gibbs and Piper method, as well as the hardness, soluble sodium percentage and the permeability index all have been used to assess the diagram quality of the groundwater of aquifers. Further, the multiple correlations and Cluster Analysis of groundwater quality parameters were carried out for further classification and interpretation of the groundwater quality. Finally, water qualities in the study area are compared with Libyan standards and WHO guidelines of drinking water and irrigation  purposes.

Technology has become an essential part of education today, and learning environment has changed from that of many years ago; students need to use technology as an alternative effective learning tool for learning English language as a foreign language (EFL). Most of current studies in the educational use of social media seem to pay more attention to the students' use of Facebook in learning. This research explores 14 university learners use of Facebook group and it mainly focuses on lecturers' role in Facebook group. This qualitative study involved observation and some interview questions. Current findings highlight that there are potential benefits to using Facebook for learning with reference that these students still need a guideline and support from their lecturers to learn English via Facebook. This paper suggests that considerable students' content knowledge of educational technology as Facebook is required to improve their learning. This study hopes to add and expand current body of knowledge about learning English in relation to Facebook used in English foreign language context. 

This study considers the diagenetic processes and the depositional settings of Lower Jurassic gypsum of the Bi'r Elghanem Formation in the northwestern of Libya. The paleo-environment study has revealed a variety of depositional environment ranging from lagoonal to fluvial deposit and evaporitic basins, which become intensely saline as a result of evaporation due to (semi-) arid environments. Samples were analyzed using elemental analysis, statistical evaluation such as Multiple Correlations, Principal Component Analysis, and mineralogical evidence to determine their mode of environmental deposition, mineralogical and geochemical composition. The geochemical results indicate that gypsum has evidence of mineral substitutions and displacement, suggesting a homologous mechanism for lithofacies and subsequent textural change. The development of gypsum minerals in a variety of lithologies and textures is aided by eustatic fluctuations in lake water level due to regional tectonism and climate.

Lithostratigraphically, the Sidi As sid Formation (Upper Cretaceous) in the El Zintan section (JabalNafusah, NW Libya) consists of three units: upper marl, middle marl with intercalations of dolostone, and lower dolostone. Based on crystal size and shape, three types of dolomite have been classified. Fine crystalline dolomite (D1) consists of nonplanar dolomites, fine to medium crystalline dolomite (D2), and very coarse, consisting of mostly planar dolomites (D-3). The Cathodoluminescence technique also showed that most of these dolomites have bright yellow to red and dull orange luminescence and zoning. Based on X-ray diffraction (XRD), all dolomites are relatively well ordered and non to nearly stoichiometric dolomite. The stable isotopic studies and element analysis show that the major elements such as sodium (D1: 412.166 ppm; D2: 175 ppm; D3: 420 ppm), strontium (D1: 107 ppm; D2: 85 ppm; D3: 81.2 ppm), manganese (D1: 271 ppm; D2: 91 ppm; V3: 242 ppm), and iron (D1: 4856.66 ppm; D2: 373 ppm; D3: 3287 ppm) and the values of the stable isotope of oxygen (D1:-2.202‰; D2:-2.131; D3:-4.359‰) and carbon (D1: 2.080; D2: 2.076‰; D3: 1.581‰). The values of major elements and depletion of the carbon and oxygen isotopes can be related to the effects of temperature diagenetic, and mesosaline reflux of dolomitizing fluids during the early diagenesis. These dolomites originated in a tidal environment in this Formation. The major sources of magnesium for the dolomites are seawater and hypersaline fluids.
