OCCURRENCE AND FAUNA COMPOSITION OF GRUOND BEETLES IN WHEAT FIELDS

According to this research, among the collected Coleoptera the most numerous were the epigeobiotic species of the families Carabidae, Silphidae, Staphilinidae, Curculionidae, Scarabaeidae and Chrysomelidae. Based on the number of individuals and the percentage of encounters in the studied areas, the Carabidae stand out in comparison to the other Coleoptera which is proved by the qualitative and quantitative composition of the collected fauna (36 species and 7,768 individuals). The representatives of the family Carabidae are of certain economic significance as well. Within this family the dominant and subdominant species in 2006 year were Agonum (Anchomenus) dorsalis (Ponto ppidan,1763) and Pterostichus (Poecilus) cupreus (Linnaeus, 1758) and in 2007, besides those, the same quantitative category also comprised the species Stomis pumicatus (Panzer,1795) , Trechus quadristriatus (4-stiatus) (Schrank, 1781), Harpalus (Pseudoophonus) rufipes (De Geer, 1774) and Harpalus distinguendus (Duftschmid, 1812)

Diagnostics of plasma in the ionospheric D-region: detection and study of different ionospheric disturbance types

Here we discuss our recent investigations of the ionospheric plasma by using very low and low frequency (VLF/LF) radio waves. We give a review of how to detect different low ionospheric reactions (sudden ionospheric disturbances) to various terrestrial and extra-terrestrial events, show their classification according to intensity and time duration, and present some methods for their detections in time and frequency domains. Investigations of detection in time domain are carried out for intensive long-lasting perturbations induced by solar X-ray flares and for short-lasting perturbations caused by gamma ray bursts. We also analyze time variations of signals used in the low ionospheric monitoring after earthquake events. In addition, we describe a procedure for the detection of acoustic and gravity waves from the VLF/LF signal analysis in frequency domain. The research of the low ionospheric plasma is based on data collected by the VLF/LF receivers located in Belgrade, Serbia

Bans to conceive the employment relationship - legitimate goals and limitations

Проучавање сметњи за заснивање радног односа, легитимних циљева и ограничења њиховог регулисања је од посебног доктринарног значаја, с обзиром на то да је у питању савремена, актуелна, међутим још увек недовољно истражена тема. Целовита обрада сметњи за заснивање радног односа, обављање слободних професија и вршење јавних функција и систематизација научних ставова у предметној области, указује на модалитете унапређења домаћег позитивног права сагласно критичкој анализи страног права и праксе. Сметње као правне чињенице које привремено или трајно лицу које испуњава услове онемогућавају да заснује радни однос, стекне звање, ради ван радног односа, обавља слободне (лиценцне) професије, буде бирано, постављено и именовано на јавну функцију, односно чије наступање може да има за последицу престанак стеченог статуса, прописују се у циљу заштите легитимних интереса. Услови за запослење као претпоставке способности субјекта да заснује радни однос, разликују се од сметњи, које онемогућавају заснивање радног односа са лицем које испуњава прописане услове. Анализа сметњи и диференцијација од услова, поред научних има и циљеве стручне природе, јер треба да послужи не само као референца за de lege ferenda развој домаћег права, већ и за успостављање одговарајуће (судске) праксе. У истраживању сметњи за заснивање радног односа, обављање слободних професија и јавних функција коришћени су правни методи ради разматрања извора домаћег и међународног радног права, научне и стручне литературе, односно историјскоправни са упоредноправним и методом социологије права, у циљу проучавања еволуције у перцепцији и нормирању сметњи, као и одређивању сличности и разлике између позитивног права Републике Србије и других земаља у разматраној области.The study of bans to conceive the employment relationship, legitimate goals and limitations of their regulation is of special doctrinal importance, considering that it is a modern, current, but still insufficiently researched topic. A comprehensive treatment of bans to conceive the employment relationship, performance of the liberal professions and public functions and systematization of scientific views in this area, indicates the modalities of improving domestic positive law in accordance with the critical analysis of foreign law and practice. Bans as legal facts which temporarily or permanently to a person who meets the requirements enables conceiving the employment relationship, acquiring titles, work outside employment, conducting free (license) profession, election, designation and appointment to public functions, or the occurrence of which may result in the termination of acquired status are prescribed in order to protect the legitimate interests. Requirements for employment as an assumption of ability of a subject to conceive employment relationship differ from bans, which prevent the conceiving of employment relationship to a person who meets the prescribed requirements. Analysis of bans and differentiation from requirements, besides scientific also has goals with professional nature, because it should serve not only as a reference for de lege ferenda development of domestic law, but also for establishment of an appropriate (judicial) practice. In a research of bans to conceive the employment relationship, performing the liberal professions and public functions legal methods are used for the consideration of sources of national and international labor law, science and professional literature, as well as historically legal with comparative legal and method of sociology of law, in order to study the evolution of perception and regulation of bans and to determine the similarities and differences between the positive law of the Republic of Serbia and other countries in the considered area

The A-test: Reliability of functional recovery assessment during early rehabilitation of patients in an orthopedic ward

Background/Aim. There are few tests for evaluation of functional abilities of patients surgically treated for hip fractures or osteoarthritis during early rehabilition period. The aim of this study was to investigate reliability (interobserver reproducibility and internal consistency) of the A-test, an original test for functional recovery evaluation during early rehabilitation of patients in an orthopedic ward. Methods. The investigation included 105 patients (55 patients with hip osteoarthritis that underwent arthroplasty and 50 surgically treated patients with hip fracture). It was conducted in an orthopedic ward during early inpatient rehabilitation (from 1st to 5th day). For their functional recovery evaluation during early rehabilitation we used the A-test, a performance-based test with 10 items for assessing basic activities by six level ordinal scale (0-5). For internal consistency of the test the Cronbach coefficient alpha was calculated for the A-test results collected during early rehabilitation for all patients (105 patients x 5 days = 525 measures) and separately for the results of patients with hip osteoarthritis (275 measures) and hip fracture (250 measures). Values of this coefficient > 0.7 imply good internal consistency of the test. Interobserver reproducibility was estimated as follows: two physiotherapists together conducted physical therapy with the patients, and then, separately, rated the performance of each activity from the test (78 measures). The agreement between their estimations was expressed by the linear weighted kappa coefficient (for very good agreement values of kappa coefficient have to be in the range 0.81-1). Results. The Cronbach coefficient alpha was 0.98 (the results of all the patients and the results of the patients with hip osteoarthritis) and 0.97 (the results of the patients with hip fracture). The values of kappa coefficient were in the range 0.81-0.92 for all items. Conclusion. The A-test is a reliable instrument for everyday evaluation of functional recovery during early rehabilitation of patients surgically treated in an orthopedic ward

Endoscopically removed giant submucosal lipoma

Background. Although uncommon, giant submucosal colon lipomas merit attention as they are often presented with dramatic clinical features such as bleeding, acute bowel obstruction, perforation and sometimes may be mistaken for malignancy. There is a great debate in the literature as to how to treat them. Case report. A patient, 67-year old, was admitted to the Clinic due to a constipation over the last several months, increasing abdominal pain mainly localized in the left lower quadrant accompanied by nausea, vomiting and abdominal distension. Physical examination was unremarkable and the results of the detailed laboratory tests and carcinoembryonic antigen remained within normal limits. Colonoscopy revealed a large 10 cm long, and 4 to 5 cm in diameter, mobile lesion in his sigmoid colon. Conventional endoscopic ultrasound revealed 5 cm hyperechoic lesion of the colonic wall. Twenty MHz mini-probe examination showed that lesion was limited to the submucosa. Since polyp appeared too large for a single transaction, it was removed piecemeal. Once the largest portion of the polyp has been resected, it was relatively easy to place the opened snare loop around portions of the residual polyp. Endoscopic resection was carried out safely without complications. Histological examination revealed the common typical histological features of lipoma elsewhere. The patient remained stable and eventually discharged home. Four weeks later he suffered no recurrent symptoms. Conclusion. Colonic lipomas can be endoscopically removed safely eliminating unnecessary surgery

The Role of Ovalbumin in Manganese Homeostasis during Chick Embryogenesis: An EPR Spectroscopic Study

Ovalbumin (OVA), a protein vital for chick embryo nutrition, hydration, and antimicrobial protection, together with other egg-white proteins, migrates to the amniotic fluid and is orally absorbed by the embryo during embryogenesis. Recently, it has been shown that for optimal eggshell quality, the hen diet can be supplemented with manganese. Although essential for embryonic development, manganese in excess causes neurotoxicity. This study investigates whether OVA may be involved in the regulation of manganese levels. The binding of Mn(II) to OVA was investigated using electron paramagnetic resonance (EPR) spectroscopy. The results show that OVA binds a maximum of two Mn(II) ions, one with slightly weaker affinity, even in a 10-fold excess, suggesting it may have a protective role from Mn(II) overload. It seems that the binding of Mn(II), or the presence of excess Mn(II), does not affect OVA’s tertiary structure, as evidenced from fluorescence and UV/vis measurements. Comparative analysis with bovine and human serum albumins revealed that they exhibit higher affinities for Mn(II) than OVA, most likely due to their essentially different physiological roles. These findings suggest that OVA does not play a role in the transport and storage of manganese; however, it may be involved in embryo protection from manganese-induced toxicity

Career guidance and counseling of European documents

Tradicionalno shvaćenim, danas se suprotstavljaju koncepti savremenih karije- ra, koji sobom nose i brojne promene samog procesa karijernog vođenja i saveto- vanja. Karijerno vođenje i savetovanje tako postaje prepoznato kao instrument pro- mena na ličnom i društvenom nivou, a pre svega posmatra se kao doživotan proces. U radu se razmatra karijerno vođenje i savetovanje u okvirima evropskih dokume- nata. Istraživanje evropskih dokumenata sprovedeno je sa ciljem ispitivanja osno- vnih karakteristika karijernog vođenja i savetovanja odraslih, koje se u tim doku- mentima javljaju. Preciznije, pokušali smo da identifikujemo aktivnosti i nosioce karijernog vođenja i savetovanja, kao i ciljne grupe koje su tim procesom obuhva- ćene. Identifikovanje pomenutih aspekata posmatra se kao značajan resurs u razu- mevanju aktuelnih tendencija na ovom polju.Traditionally understood careers, are now being opposed to the concept of mo- dern careers which brings along a great number of changes in the process of car- rer guidance and counseling. Career guidance and counseling thus becomes reco- gnized as an instrument of change on a personal and social level. Also, the process is recognized as a lifelong process. The paper discusses the career guidance and counseling in the terms of European documents. Research of European documents was conducted to examine the main characteristics of carrer guidance an counse- ling for adults, which are listed in these documents, more accurately, identification of the activies and the holders of career guidance and counseling, and also identifi- cation of the target groups which are included in the process. Identification of these aspects is recognized as an important resource in the understanding of the new ten- dencies in this area

Ocjenjivanje drva prema čvrstoći kao nužna osnova za projektiranje konstrukcija na području bivše Jugoslavije: dio 1.

Classification of timber for various commercial purposes is essential for its proper application in order to ensure the reliability and economic use. Visual grading of structural timber is commonly used in a number of EU countries, with different grading national standards optimized for locally available wood. Countries in the ex-YU region are traditional partners in wood trade and had the same standards for visual grading, but in most of the regions these standards are not completely compliant with EN requirements. Consequently, that leads to the fact that the most of regionally available structural timber is not assigned into strength classes, which is the starting point for the limit-state concept in design of timber structures. The aim of this paper is to emphasize the lack of strength classification of structural timber in the ex-YU region, which is a prerequisite for the design of timber structures made by civil engineers. Based on an overview of visual classification types with regional experience in grading, relevant EN standards, and differences in design concepts with possible consequences of grading approach, it can be concluded that “quality” grades and “strength” classes are not easily comparable.Klasifikacija drvne građe za različite komercijalne namjene ključna je za njezinu pravilnu upotrebu kako bi se zajamčila sigurna i ekonomična uporaba. Vizualno ocjenjivanje konstrukcijskog drva obično se provodi u mnogim zemljama EU-a uz pomoć različitih nacionalnih standarda ocjenjivanja optimiziranih za lokalno dostupno drvo. Zemlje bivše Jugoslavije tradicionalni su partneri u međusobnoj trgovini drvom i imale su zajedničke standarde za vizualno ocjenjivanje drvne građe, ali u većini njih ti standardi nisu u potpunosti usklađeni s EN zahtjevima. To posljedično rezultira činjenicom da većina regionalno dostupnoga konstrukcijskog drva nije razvrstana u klase čvrstoće, što je polazište za koncept graničnog stanja u projektiranju drvnih konstrukcija. Cilj rada jest upozoriti na nepostojanje klasifikacije čvrstoće konstrukcijskog drva na području bivše Jugoslavije, a to je preduvjet za projektiranje drvnih konstrukcija, što je posao građevinskih inženjera. Na temelju tipova vizualne klasifikacije i regionalnih iskustava u ocjenjivanju, relevantnih EN normi te razlika u konceptima projektiranja s mogućim posljedicama pristupa ocjenjivanju, zaključeno je da ocjene razreda kvalitete i klase čvrstoće u promatranim zemljama jednostavno nisu međusobno usporedive

Modulacija eksperimentalnog autoimunog encefalomijelitisa (EAE) DA pacova levamizolom

We investigated the influence of an antiparasitic drug, levamisole (2,3,5,6 - tetrahydro - 6- phenyl-imidazo (2,1 - b) thiazole -hydrochloride) with potent immunomodulatory properties on the course and development of experimental autoimmune encepha-lomyelitis (EAE). EAE was induced in female Dark Agouti (DA) rats aged two months by immunization with guinea pig spinal cord in complete Freunds adjuvant. Following immunization animals were subcutaneously treated every other day with 2.2 mg/kg levamisole. The course, development and characteristics of this autoimmune process were monitored as indirect indicators of immune system activity. Our results indicate that in EAE levamisole exerts immunosuppressive effects when administered every other day from the moment of immunization until the end of the disease. This application regime and dose postponed the onset of the first clinical signs, shortened the duration of the disease, abrogated the severity of clinical symptoms and accelerated the recovery of sick animals. In the period of induction and during EAE, levamisole also decreased the severity of changes in the cerebral perivascular spaces. In the peripheral blood of levamisole treated animals with induced EAE, a significant increase of CD4-CD8+ T cells was demonstrated. Furthermore, all rats with induced EAE had decreased numbers of CD4+CD8- T cells in their blood. These changes were in correlation with clinical signs of EAE.U ovom radu su prikazani rezultati ispitivanja anthelmintika levamizola (2,3,5,6 tetrahidro - 6 - fenil - imidazo (2,1 - b) tiazol hidrohlorida) sa snažnim imunomodulatornim svojstvima na tok i razvoj eksperimentalnog autoimunog encefalomijelitisa (EAE). EAE je indukovan imunizacijom ženki pacova soja DA (Dark Agouti) starih dva meseca pomoću homogenata kičmene moždine zamorčeta u kompletnom Freundovom adjuvansu. Posle imunizacije, životinje su tretirane subkutanim injekcijama levamizola (2.2 mg/kg) svaki drugi dan a praćeni su tok, razvoj i karakteristike ovog autoimunog oboljenja kao indirektni indikatori aktivnosti imunološkog sistema. Postignuti rezultati ukazuju dalevamizol ispoljava imunosupresivno delovanje u modelu EAE ako se aplikuje svaki drugi dan od momenta imunizacije do kraja bolesti. Primenjena doza i režim aplikacije odložili su momenat pojavljivanja prvih kliničkih simptoma, skratili trajanje bolesti, ublažili ispoljavanje simptoma i ubrzali oporavak bolesnih životinja. U periodu indukcije i tokom EAE-a levamizol je smanjio stepen promena u cerebralnim perivaskularnim prostorima. U ženskoj krvi ženki pacova sa indukovanim EAE i tretiranim levamizolom uočeno je značajno povećanje broja CD4-CD8+ T ćelija. Osim toga, u obe imunizovane grupe životinja zapaženo je smanjenje broja CD4+CD8- ćelija. Ove promene su bile u skladu sa kliničkom slikom bolesti
