Demodikoza pasa na teritoriji grada Niša

This paper describes cases of demodicosis in dogs from the territory of the city of Niš. The objective of the investigations was to learn more about the parameters that can influence the susceptibility of certain dogs to the cause of demodicosis, such as: age, hair length, sex, and seasonal dynamics of the incidence of the disease. It was established following examinations of 76 dogs suspected of demodicosis that they were all infected with the specie Demodex canis. The changes were localized or generalized. In the total number of infected dogs, there was a larger share of males (61.84%) than females (38.16%). The number of dogs diseased with demodicosis was twice higher in shorthaired than in long-haired animals. The most frequently infected were dogs of the Doberman and German Shepherd breeds. The number of male and female animals among short-haired dogs diseased with demodicosis was equal, while there were more males among the long-haired animals. The biggest number of infected animals was in the category of young dogs, up to one year of age, and they accounted for 65.79% of the total number of diseased animals, which shows without any doubt that younger dogs are more susceptible to demodicosis. There were more infected dogs in the period autumn-winter than in the period spring-summer.U ovom radu opisani su slučajevi demodikoze kod pasa sa teritorije grada Niša. Cilj ispitivanja je bio da se nešto više sazna o parametrima koji mogu da utiču na prijemčivost određenih pasa prema uzročniku demodikoze kao što su: životno doba, dužina dlake, pol i sezonska dinamika pojavljivanja bolesti. Pregledom 76 pasa suspektnih na demodikozu, ustanovljeno je da su svi bili infestirani vrstom Demodex canis. Promene su bile lokalizovane ili generalizovane. U ukupnom broju infestiranih pasa veći je bio udeo mužjaka (61,84%) nego ženki (38,16%). Broj pasa obolelih od demodikoze bio je dva puta veći kod kratkodlakih u odnosu na dugodlake pse. Najčešće infestirani su bili psi rase doberman i nemački ovčar. Broj muških i ženskih jedinki kod kratkodlakih pasa obolelih od demodikoze bio je ujednačen, dok je kod dugodlakih bio veći broj mužjaka. Najveći broj infestiranih je bio iz kategorije mladih pasa, uzrasta od godinu dana i njihov udeo u ukupnom broju obolelih bio je 65,79 posto, što nesumnjivo ukazuje da su demodikozi podložniji mlađi psi. U periodu jesen-zima bio je veći broj infestiranih pasa nego u periodu proleće-leto

ACT OF IMPLEMENTATION OF TOYOTA SYSTEM

The production system developed by Toyota Motor Corporation was developed to provide best quality, lowest costs, and shortest lead time through the elimination of losts. Kiichiro Toyota, son of Sakichi and founder of the Toyota automobile factory, developed the concept of Just-in-Time in the 1930's. He decreed that by this act Toyota would contain no excess inventory and that Toyota would strive to work both in partnership with suppliers and level production. The Toyota production system has been compared to squeezing water from a dry towel. Importance of Toyota sistem for production proces can sum up on the next way : Reducing costs includung the elimination of waste, With help without warehouse production – elimination the „excess inventory in production“, Reducing time of handwork using maxim „smallest posible of serve“, To reach a production without warehouse – its demand a production in small series, Its not neccessary to produce something else except that you realy nee

Intramolecular cyclization of 3β-acetoxy-16-picolinylidene-5-androsten-17-one by catalytic hydrogenation

Intramolecular cyclization by catalytic hydrogenation of 3β-acetoxy-16-picolinylidene-5-androsten-17-one (IV) (80° and 50-60 atm of hydrogen pressure over Pd/C as catalyst) gives rise to the formation of two cyclic products, namely, 5′,6′,7′,8′-tetrahydro-2′αH-3′αH-9′αH-3β-acetoxy-androst-5-eno [16.17-b]indolizine (VII) and its 9′βH-isomer (VIII), in a total yield of over 80%, the ratio of the two isomers being 3:1. The cyclized products have structures similar to naturally occuring alkaloid solanidine. A mechanism is proposed for the cyclization

ANALYSIS OF MONITORING OF CONNECTION BETWEEN REENGINEERING ECONOMIC PARAMETERS IN SMALL AND MEDIUM ENTERPRISES USING THE METHOD OF CREATING OPTIMAL QUESTIONNAIRE

The analysis of this type of connecting economic parameters by using reengineering is reflected through the formation of an Optimal questionnaire Go which allows connecting the N parameters by the question of connection and their peaks are arranged into a descending set in terms of their ranks

Measurements of physical-chemical characteristics of dairy plant waste waters

Characteristics of waste waters of the dairy industry are specific and differ essentially from waste waters of other branches of the food industry. The complexity of production in dairy plants with several units for different products render the problem of waste waters of this industry particularly complex. Waste waters of the AD Imlek dairy plant were sampled and their chemical characteristics were determined at different seasons of the year and at different times of the day in the years 2001 and 2007. The obtained concentrations were compared with the maximum permitted concentrations listed under the Regulations on technical and sanitary conditions for releasing waste waters into the City Sewers of the City of Belgrade

The reaction of lead tetra-acetate with some unbranched α,ω-diols

Unbranched α,ω-diols are mainly converted by means of lead tetra-acetate in refluxing benzene to the corresponding ethers of di-α-tetrahydrofuryl, di-α-tetrahydropyryl and/or α-tetrahydrofuryl-α′-tetrahydropyryl type. Thus, 1,6-hexanediol affords cis-1,4-dioxaperhydropentalene (Ia) in 15·2% yield; 1,7-heptanediol affords 1,6-dioxaspiro[4.4]nonane (II) in 29·2% yield; 1,8-octanediol cyclizes to 1,6-dioxaspiro[4.5]decane (IIIa) in 39·3% yield; 1,9-nonanediol affords a mixture of di-α-tetrahydrofurylmethane (IV, 33·2%), 2-(α-tetrahydrofuryl)α′-tetrahydropyran (IVa, 3·7%) and 1,7-di-oxaspiro[5.5]undecane (IVb, 3·3%); 1,10-decanediol is oxidized to a mixture of 1,2-di-α-tetrahydrofurylethane (V, 27·2%), and threo- and erythro-α-tetrahydrofuryl-α′-tetrahydropyrylmethanes (Va, 4·3%); and 1,11-undecanediol affords, as main product, 1,3-di-α-tetrahydrofurylpropane (VI) in 40·1% yield, together with small amounts of four other ethers which were not identified

Effects of reactive filters based on modified zeolite in dairy industry wastewater treatment process

Application of adsorbents based on organo-zeolites has certain advantages over conventional methods applied in food industry wastewater treatment process. The case study presented in this paper examines the possibilities and effects of treatment of dairy industry wastewater by using adsorbents based on organo-zeolites. The obtained results indicate favorable filtration properties of organo-zeolite, their high level of adsorption of organic matter and nitrate nitrogen in the analyzed wastewater. This paper concludes with recommendations of optimal technical and technological parameters for the application of these filters in practice
