Background: Staphylococcus aureus is one of the main causes of hospital-acquired infections, which can cause skin and soft-tissue infections, systemic infections and toxemic syndromes. The development of multiple drug resistance to this organism is posing serious threat to inpatients，these bacteria also have plenty of virulence factors which contribute to infection. \nObjectives: To determine antimicrobial susceptibility pattern of S. aureus isolates from hospitalized patients and their virulence factors and biofilm formation at two Chinese University Affiliated Hospital.\nMethods: Swabs for culture of S. aureus were obtained from patients hospitalized in two hospitals in China from June 2013 to May 2014, and 135 isolates were collected. All the strains were analyzed with phenotypic assays in order to evaluate the virulence factors and the susceptibility against antibiotics. \nResults: In 135 strains of S. aureus，113 strains of β-lactamase were positive which probably accounted for the 100% resistance obtained for both Ampicillin and Penicillin. S. aureus isolates tested for antibiotic susceptibility showed high antibiotic resistance to Ampicillin, Penicillin, Amoxicillin, Nalidixic acid, and Ceftriaxone, mid resistance to Tobramycin, Neomycin, Erythromycin, Tetracycline, Gentamicine, Streptomycin, Kanamycin, Oxacillin and Co-trimoxazole, low resistance to Norfloxacin, Cephalexin, Ciprofloxacin, Rifampicin, Clindamycin and no resistance to Vancomycin. All S. aureus isolates were positive for proteases gelatinase and elastase production. The rate of positiveness for phospholipase, lipase and DNase tests were 72.6%, 75.6% and 91.1%. 32 out of 135 tested strains were beta-hemolytic (23.7%), 58 out of 135 tested strains were alpha-hemolytic (42.9%) and the other 45 strains can produce alpha- and beta-haemolysis (33.3%). 61.5% isolates were found to be positive for biofilm production by standard tube method, while 45.2% were found to be positive biofilm producers by congo red agar method.\nConclusions: On in vitro sensitivity testing, ampicillin, penicillin and amoxicillin were the least effective. Norfloxacin, cephalexin, ciprofloxacin, rifampicin, clindamycin and vancomycin were the most effective antibiotics. Clinical S. aureus isolates were producers of a variety of extracellular hydrolytic enzymes and can form biofilm, which might have an important role in the pathogenesis of infections and drug resistance.

The tail region of fat tail sheep has important adaptation implications in that it stores energy during times of plentiful nutrition and mobilizes the stored energy during times of nutritive deficits. However, the function of the fat tail may have less utility for lambs destined for meat production in the feedlot and may actually divert feed energy from growth. Consequently, it is of interest to evaluate effects of tail removal in fat tail feedlot lambs. The objective of this study was to evaluate the impact of tail removal on blood parameters in Lanzhou-fat-tail Sheep and Mongolian Sheep. Eighteen Lanzhou fat tail sheep and Mongolian rams were selected for this study and tails were surgically removed in 9 of each breed. Blood samples were taken every 45 d for 135 d. Blood parameters measured included glucose (GLU), total bilirubin (T-bill), direct bilirubin (D-bill), total protein (TP), albumin (ALB), total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), lipase (LIP), and computed immunoglobulin (IMM). Results showed that: day was generally significant for all blood parameters studied. Breed differences were evident for TP, TC, TG, LDL (P<0.01), and for HDL and LPS (P<0.05). Treatment differences occurred in TP and IMM (P<0.01), and for T-bill, TC, TG and LDL (P<0.05). There was an interaction among breed, day and treatment for some blood parameters. Results indicate that the responses of sheep due to tail removal may be different between Lanzhou-fat-tail Sheep and Mongolian Sheep. This may be due to different pathways of fat deposition between these two breeds of sheep. However, the mechanism of fat deposition in these breeds needs further study.

Smart systems implemented within seeds separation technologies aim to increase equipment performances and ensuring a higher quality product by removing foreign objects from the processed seeds. The first condition to obtain rich crops is to use quality planting seed material with high germination power and free of any kind of parasitic weed seeds.

The aim of this work was to investigate and compare the phytoconstituents, mineral profile, anti-oxidant, antibacterial and antifungal activities of both gemm and native Foeniculum vulgare (fennel) native to Pakistan. Qualitative and quantitative analyses revealed that gemm Foeniculum vulgare contains 1.36mg/g Fe, 0.843mg/g, Ca 0.19g alkaloid and 1.8g flavonoids much higher than native Foeniculum vulgare which contains 0.49mg/g Fe, 0.37mg/g Ca, 0.14g alkaloids and 1.4g flavonoids. The antioxidant activity was evaluated by the reduction of 2, 2-diphenyl-1-picryl hydrazyl (DPPH) and measuring percent inhibition of peroxidation in linoleic acid system. The disc diffusion and modified resazurin microtitre-plate assays were used to evaluate the inhibition zones (IZ) and minimum inhibitory concentration (MIC) of both gemm and native Foeniculum vulgare , respectively. The result of our present investigation revealed that gemm Foeniculum vulgare (fennel) exhibits tremendous anti-oxidant, antimicrobial activities and could be explored further for various industrial applications.

In this paper we present methods and techniques for assessing air quality in areas with heavy urban road traffic. The first part of the paper is dedicated to models for dispersion currently employed in Romania and also to those used at international level, along with traffic modelling in a classic urban area. The paper also contains a case study, focused on two simple junctions located in the southern side of Bucharest. A combination of measurements and modelling techniques has been used for assessing air quality there where levels of pollutant agents were varying between lower and upper threshold of evaluation.

Today, ICT plays an important role in all matters and it affects the development of creative cities. According to virtual space in this technology, it use especially for expand terms like smart schools, Virtual University, web-based training and virtual classrooms that is in parallel with the traditional teaching. Nowadays, the educational systems in different countries such as Iran are changing and start increasing creativity in the learning environment. It will contribute to the development of innovative ideas and thinking of the people in this environment; such opportunities might be cause scientific discovery and development issues. The creativity means the ability to generate ideas and numerous, new and suitable solutions for solving the problems of real and virtual individuals and society, which can play a significant role in the development of creative current physical cities or virtual borders ones in the future. The purpose of this paper was to study strategies to increase creativity in a virtual learning to develop a creative city. In this paper, citation/ library study was used. The full description given in the text, including how to create and enhance learning creativity in a virtual classroom by reflecting on performance and progress; attention to self-directed learning guidelines, efficient use of social networks, systematic discussion groups and non-intuitive targeted controls them by involved factors and it may be effective in the teaching process regarding to creativity. Meanwhile, creating a virtual classroom so that the style of class recognizes formally the creativity. Also the use of a common model of creative thinking between student/teacher is effective to solve problems of virtual classroom. It is recommended to virtual education’ authorities in Iran to have a special review to the virtual curriculum for increasing creativity in educational content and such classes to be witnesses more creative in Iran\'s cities.
