A Fuzzy AHP Model in Risk Ranking

The signification risks associated with construction projects need special attention from contractors to analyze and mange the risks. Risk management is the art and science of identifying, analyzing and responding to risk factors throughout the life cycle of the project and in the best interest of its objectives. In proposed model, we firstly identify risks in the construction projects and suitable criteria for evaluate risks and then structure the proposed AHP model. Finally we measure the significant risks in construction projects (SRCP) based on the project’s objectives by using fuzzy analytical hierarchy process (FAHP) technique.

Kokcidioza koza: učinci pokusne infekcije na određene krvne pokazatelje.

The objective of this experiment was to elucidate the aspects of differential circulatory cell responses during experimental coccidiosis in goat. A total of twenty newborn kids were selected; ten of them were infected with sporulated oocysts of the most pathogenic species of Eimeria and the remainder served as control. Blood samples were taken at 0 (before inoculation), 3, 7, 14, 17, 21, 24, 28 and 35 days post infection (dpi) and some hematological and fecal related parameters were measured. According to our data, except for a significant decrease at 24 dpi, packed cell volume (PCV) and hemoglobin (Hb) concentrations evidenced no substantial changes in the infected kids compared to controls. The percentage of the circulatory neutrophils showed remarkable increases from 7 to 24 dpi. Unlike neutrophils, the level of lymphocytes represented marked decreases from 7 to 24 dpi. In addition, circulatory eosinophils evidenced no statistical changes during the infection; however monocytes revealed a significant elevation only at 17 and 24 dpi. Substantial activations of neutrophils and lymphocytes indicate that these cells have key roles in either preventing or establishing primary infections with Eimeria in goats.Cilj pokusa bio je rasvijetliti različite odgovore stanica u krvnom optjecaju tijekom pokusno uzrokovane kokcidioze u koza. U pokus je bilo uključeno 20 novoojarene jaradi od čega je 10 bilo zaraženo sporuliranim oocistama najpatogenije vrste roda Eimeria, a ostalih 10 su poslužili za kontrolu. Uzorci njihove krvi bili su uzeti 0. (prije zaražavanja), 3., 7., 14., 17., 21., 24., 28. i 35. dana nakon zaražavanja te su bili pretraženi na neke hematološke pokazatelje. Parazitološki su bili pretraženi i uzorci izmeta. Vrijednosti hematokrita i koncentracije hemoglobina nisu pokazivale bitne promjene u zaraženih u odnosu na kontrolne životinje, osim značajnog smanjenja 24. dana nakon infekcije. Postotak optjecajnih neutrofila bio je značajno povećan od 7. do 24. dana nakon infekcije. Za razliku od neutrofila, razina limfocita bila je znantno smanjena od 7. do 24. dana poslije infekcije. Povrh toga, statistički značajne promjene ustanovljene su u broju optjecajnih eozinofila dok je broj monocita bio značajno povišen 17. i 24. dana nakon infekcije. Znatna aktivacija neutrofila i limfocita upućuju na zaključak da te stanice imaju ključnu ulogu u sprječavanju primarne infekcije kokcidijama roda Eimeria u koza

Serological survey of Toxoplasma gondii infection in the one‐humped camels (Camelus dromedarius) in the south of Iran

Abstract Background Toxoplasmosis, an important zoonotic disease, is caused by Toxoplasma gondii. Camels are one of several host species for T. gondii parasites and play an important role in the transmission of T. gondii to humans. Objectives The present study aimed to describe the seroprevalence of T. gondii in dromedary camels (Camelus dromedarius) from three provinces (Fars, Bushehr and Hormozgan), southern Iran first for this host. Methods A total of 180 serum samples were analysed for the presence of anti‐Toxoplasma IgG antibodies using the enzyme‐linked immune‐sorbent assay. Results Our results showed an overall seroprevalence of T. gondii in 15% of animals. Antibodies to T. gondii were found in sera of 27 of 180 dromedary camels from Fars, Bushehr and Hormozgan provinces, southern Iran. Age or the gender of the camel did not significantly affect the seroprevalence (p > 0.05). There was no significant association between herd‐level seroprevalence of T. gondii infection and abortion history, province location residence, history of animal keeping and history of contact with other animals (p > 0.05). Conclusions The results of this study showed the presence of T. gondii antibodies among camels in Southern Iran, which could be a public health concern. According to the prevalence of T. gondii infection in camel, the implementation of control measures to reduce infection in both definitive and intermediate hosts is needed

Robust Density of Periodic Orbits for Skew Products with High Dimensional Fiber

We consider step and soft skew products over the Bernoulli shift which have an -dimensional closed manifold as a fiber. It is assumed that the fiber maps Hölder continuously depend on a point in the base. We prove that, in the space of skew product maps with this property, there exists an open domain such that maps from this open domain have dense sets of periodic points that are attracting and repelling along the fiber. Moreover, robust properties of invariant sets of diffeomorphisms, including the coexistence of dense sets of periodic points with different indices, are obtained

Antibody Tracing, Seroepidemiology and Risk Factors of Bovine Respiratory Syncytial Virus and Bovine Adenovirus-3 in Dairy Holstein Farms

Antibody tracing, risk factors and seroepidemiology of bovine respiratory syncytial virus and bovine adenovirus-3 were investigated in 22 Industrial and Semi-Industrial dairy Holstein farms. Serum samples (n=736) from various ages of unvaccinated cows were collected from May to September 2012. Risk factors including age, past history of respiratory diseases, amount of milk production, husbandry type and herd size were considered. Data were analyzed by Chi-square and logistic regression. Results indicated that the infection with some of individual viruses was related to past history of respiratory disease and herd size. No specific pattern was seen on the effect of level of milk production on seropositivity of animals. The seroprevalence for BRSV and BAV-3 were 89.1% and 88%, respectively. The present study indicates that infections of bovine respiratory viruses frequently occur in cattle of Fars province and the main viral cause of primary occurrence of respiratory diseases may be due to aforementioned viruses
