Technological quality of wheat cultivars from new breeding program (Zvezdana and NS3-5299/2) and comparison to the technological quality of wheat cultivars commonly used in agricultural practice (NS Rana 5, Ljiljana, pobeda and Evropa 90)

Common wheat (Triticum aestivum) is one of the most important food crops. For this reason at cereals industry has been a long history of using descriptive empirical measurements of rheological properties to predict bread-making quality. In this paper technological quality and rheological properties of two wheat cultivars from new breeding program and (Zvezdana and NS3-5299/2) were examined by using traditional and new equipment in Serbian practice and compared with wheat cultivars which have been used in agricultural practice for more than a decade (NS Rana 5, Ljiljana, Pobeda and Evropa 90). Extensograph extensibility of new cultivars, Zvezdana and NS3-5299/2 were in the level of the best results of commercial cultivars. However, extensigraph resistance of these cultivars was low which influenced that complex property such as extensigraph ratio was also poor, but still in the range which allows good breadmaking quality Moreover, according to alveograph properties, only the new cultivar NS3-5299/2 out of all investigated cultivars under the applied production conditions fulfilled the international standards required for export and trading goods

Work ability evaluation in neurosarcoidosis: A case report

Sarcoidosis is a multisystemic granulomatous disease of unknown etiology which affects most frequently the hilar lymph nodes and lungs. Symptomatic involvement of the central nervous system may develop in patients diagnosed with sarcoidosis or it may be the initial manifestation of the disease. This is a case report of 48-year old female patient admitted to our clinic for evaluation of working ability. The patient had a total of 24 years of service and occupational exposure and she has been employed as supplies procurement officer. On admission, she complained of the following discomforts: eye-lid pain, intellectual fatigue, psychic uneasiness, forgetfulness, dyspnea and productive cough. Neurological findings indicated the presence of the right eye ophthalmoplegia, psychoorganic syndrome and neurosarcoidosis. Ophthalmological examination evidenced bilateral ptosis and presence of anisocoria. Magnetic resonance imaging revealed discrete focal lesions of the pons (paracentral left) and parietal corona radiata of the left hemisphere. Based on performed examinations and diagnostics procedures, final evaluation of patient’s working ability concluded that the patient was not capable of psychic strains and jobs associated with material accountability

The Influence of the Weather Conditions on Traffic Accidents With the Most Severe Consequences in the Republic of Srpska

Traffic accidents with the most severe consequences, i.e. killed in traffic accidents and great material damage, are the result of numerous complex impact factors. Among these important factors, there are different time parameters, that is, meteorological parameters. Research on the impact of weather parameters on the occurrence of traffic accidents was the subject of research in the early 70s of the twentieth century. Weather conditions usually have a double impact on the occurrence of traffic accidents such as: the impact on the risk of a traffic accident and the impact on the exposure to the risk of an accident. In other words, it can be said that the time parameters influence directly and indirectly on the safety of traffic, or the occurrence of traffic accidents. Namely, it has been proven that the weather conditions influence the change in the structure of the traffic flow (change of mode of transport), as well as the total number of realized trips. Although the impression is that the impact of weather conditions on the occurrence of traffic accidents is unambiguous and clear, concrete research on the impact of weather conditions is quite rare and the results sometimes differ from the expected ones. Through a review report, a special aspect of the analysis will focus on identifying concrete changes in the characteristics of time, with the aim of recognizing their impact on the number of traffic accidents with the most severe consequences in the Republic of Srpska

Investigation of relations between HMW glutenin composition and rheological propeties of contemporary wheat varieties

Among cereal scientists it is widely accepted that rheological properties of dough, examined by different types of equipment, but also the structure of high molecular weight (HMW) glutenin subunits are highly related to wheat baking properties. Farinograph, Extensigraph and Amilograph properties and lab-on-a-chip (LoaC) electrophoresis analysed composition of HMW glutenins of twenty different wheat varieties grown in three different years (2008, 2009 and 2010) were determined. Based on the occurrence of HMW glutetnin fraction of identified molecular weights (131, 133, 139, 148, 186 and 218 kDa) analyzed wheat varieties were, independently of the growing season divided in four groups under which varieties with the same HMW compositions were comprised. Rheological properties were compared among the groups of varieties with the same HMW glutenin compositions. The group which differentiated in comparison to the other groups on the basis of presence of the fraction of HMW glutenin with the highest molecular weight of 218 kDa had statistically higher farinograph quality number than other groups. The group in which both HMW glutenin fractions with the lowest molecular weights of 131 and 133 kDa were present was characterized in comparison to other groups with statistically lower farinograph quality number and extensograph energy, and statistically higher farinograph softening degree. In the group which differentiated from the other groups based on presence of HMW fraction of 139 kDa amilograph peak viscosity was statistically higher than in other groups

Morbidity patterns of workers employed in pharmaceutical-chemical industry

Introduction. Work in pharmaceutical-chemical industry is characterized by exposure to numerous hazards, both physical (microclimate, illumination, noise) and chemical (organic solvents). Organic solvents can cause damage to many organic systems and have carcinogenic, teratogenic and mutagenic effects. Objective. The aim of this study was to analyze patterns of chronic morbidity of workers employed in pharmaceuticalchemical industry during 2002. Method. The study was conducted in the pharmaceutical- chemical industry "Zdravlje" Leskovac in 2002. A total of 143 workers in workplaces with special working conditions - exposed to chemical hazards as well as 40 workers from control group took part in the study. The physical examinations of the participants were performed at the Department of Occupational Health in Health Center, Leskovac. Results. Heart diseases were the most frequent both among exposed workers (17.8%) and in control group (33.3%). Respiratory diseases were at the second place (16.9% in the exposed group, and 7.4% in control group). Arterial hypertension was diagnosed in 14.7% workers occupationally exposed to hazards, and in 12.5% workers from control group (p>0.05). Chronic bronchitis was diagnosed in 17.5% of the exposed workers and in only 5.0% of controls (p>0.05). The highest prevalence of diseases in both groups was observed among workers aged 40-49 years, with 20-29 years of exposure working time. 73.4% of the exposed workers and 85% of control workers were capable of work (p>0.05). Conclusion. Workers occupationally exposed to hazards in pharmaceutical-chemical industry have higher prevalence of various diseases compared to non-exposed workers, which can be the result of work, working conditions and work activity. Preventive measures should be directed towards the decrease of occupational hazards and unfavorable working conditions and increase of work protection. Regular physical examinations of workers are of prime importance for the prevention of occupational morbidity, traumatism and invalidity.
