Silymarin is derived from the milk thistle plant, and possesses numerous pharmacological actions, including hepatoprotective, anti-inflammatory, antioxidant, and anticancer properties. The aim of the study was to the determination of influence different concentrations of Silymarin on the rumen performance in 30 local lambs (divided into three groups of 10 lambs each). In the first and second groups, 420 and 210 mg kg-1 of silymarin were administered for 8 weeks, and the third group was the control, which received normal saline solution. The parameters evaluated included the level of volatile fatty acids (VFAs), ammonia and pH in the rumen. Furthermore, the in vitro digestibility of ash, protein, fat and dry matter was investigated. These parameters were examined fortnightly, for eight weeks. The results showed that the level of volatile fatty acids and pH increased in the rumen in G1 and G2 compared to the control group, while the level of ammonia decreased in the rumen in G1 and G2 when compared to G3 (p<0.05). Silymarin increased the in vitro digestibility of crude ash (CA), crude protein (CP), crude fat (CF) and crude dry matter (CDM) in the rumen of lambs. These results indicate that silymarin can improve the digestibility of nutrient elements in the lamb rumen. Keywords: ammonia; digestibility; crude ash; crude protein; crude fat. Concentrações de silimarina nas atividades ruminais de cordeiros RESUMO: A silimarina é derivada da planta do cardo mariano e possui inúmeras ações farmacológicas, incluindo propriedades hepatoprotetoras, anti-inflamatórias, antioxidantes e anticancerígenas. O objetivo do estudo foi determinar a influência de diferentes concentrações de silimarina no desempenho ruminal de 30 cordeiros locais, divididos em três grupos (de 10 cordeiros cada). No primeiro e segundo grupo foi administrado 420 e 210 mg kg-1 de silimarina durante 8 semanas, e, o terceiro grupo foi o controle, que recebeu solução salina normal. Os parâmetros avaliados incluíram o nível de ácidos graxos voláteis (AGVs), amônia e pH no rúmen. Além disso, investigou-se a digestibilidade in vitro de cinzas, proteínas, gorduras e matéria seca. Esses parâmetros foram examinados quinzenalmente, durante oito semanas. Os resultados mostraram que o nível de ácidos graxos voláteis e pH aumentaram no rúmen em G1 e G2, em comparação com o grupo controle, enquanto, o nível de amônia diminuiu no rúmen em G1 e G2 quando comparado com G3 (p<0,05). A silimarina aumentou a digestibilidade in vitro da cinza bruta (CA), proteína bruta (PB), gordura bruta (CF) e matéria seca bruta (CDM) no rúmen dos cordeiros. Esses resultados indicam que silimarina pode melhorar a digestibilidade dos elementos nutrientes no rúmen do cordeiro. Palavras-chave: amônia; digestibilidade; cinza bruta; proteína bruta; gordura bruta.
Background: Severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) is still a severe threaft for human health currently, and the researches about it is a focus topic worldwide.
Aim of the study: In this study, we will collect some laboratory results of the patients with coronavirus disease (COVID-19) to assess the function of liver, heart, kidney and even pancreas.
Subjects and Methods: Laboratory results of the patients with COVID-19 are collected. The biochemical indices are classified and used to assess the according function of liver, heart, kidney; meantime, and blood glucose is also observed and taken as an index to roughly evaluate pancreas.

obtained from vacuum distillation unit of lube oil plant of Daura Refinery, using solvent extraction process.
In this study furfural solvent was used to extract the undesirable materials which reduce the viscosity index of raw
lubricating oil fraction.
The studied effecting variables of extraction were extraction temperature range from 70 to 110°C, and solvent to oil
ratio range from 1:1 to 4:1 (wt/wt).
The n-d-M method was used for calculation of carbon distribution and structural group analysis of the raffinate
produced from furfural extraction.

Materials recycling has a significant economic and environmental impact; as a result, steel, aluminium, plastic, and other recyclable materials have been pushed for use in construction materials. One of these recyclable materials is the crumb rubber, has been considered as a pavement component. The general behaviour of the composite rubber-hot mix asphalt system would be varied from that of the conventional rubber free mix. In this review, desirable characteristics of hot mix asphalt are highlighted first. Also, effect of gradation and the main types of rubber are specified. Afterward, many studies that considered the crumb rubber as a waste product and its associated mixture and modifiers are reviewed. The factors affect the crumb
... Show MoreThe effects of three different additives formulations namely Lubrizol 21001, HiTEC 8722B and HiTEC 340 on the efficiency of VII namely OCP of three base lubricating oils namely 40 stock and 60 stock and 150 stock at four temperatures 40, 60, 80 and 100oC were investigated. The efficiency of OCP is decreased when blended with 4 and 8 wt% of Lubrizol 21001 for all the three base oil types. But it is increased when adding 4 wt% and 8 wt% of H-8722B in 40 stock. While for 60 stock and 150 stock the OCP efficiency decreased by adding 4 and 8 wt% of H-8722B. In the other hand, it is decreased with a high percentage by adding 4 and 8 wt% of H-340 for 60 stock and 150 stock and for 40 stock it is increased by adding 4 wt% of H-340 and decreased
... Show MoreThe electrospun nanofibers membranes (ENMs) have gained great attention due to their superior performance. However, the low mechanical strength of ENMs, such as the rigidity and low strength, limits their applications in many aspects which need adequate strength, such as water filtration. This work investigates the impact of electrospinning parameters on the properties of ENMs fabricated from polyacrylonitrile (PAN) solved in N, N-Dimethylformamide (DMF). The studied electrospinning parameters were polymer concentration, solution flow rate, collector rotating speed, and the distance between the needle and collector. The fabricated ENMs were characterized using scanning electron microscopy (SEM) to understand the surface morphology and es

This paper presents an experimental and analytical campaign to study the behavior of axially loaded columns constructed from recycled aggregates. The latter was used instead of natural aggregates, and they were collected from the waste of previous concrete constructions. Different concrete mixtures made from varying amounts of recycled aggregates ranged from 0 to 50% of the total coarse aggregate were conducted to achieve 28 MPa. The effect of steel fibers is another investigated variable with volumes ranged from 0 to 2% concerning concrete’s mixture. The experimental
