Proizvodnja soje (Glycine max.) u svetu i kod nas

Areas under soybean in the world in 2013 amounted to 111.27 million hectares, with the total production of 276.40 million tonnes. America is the world's largest producer of soybean, with an area of 85.63 million ha, or with total world share of 76.95%, followed by Asia with an area of 20.69 million hectares and Europe with an area of 3.18 million hectares and total production of 5.94 million tonnes. The Republic of Serbia is among the largest producers oil crops in Europe. In 2013, the average soybean yields in Serbia were at the level of the average global yield while production amounted to 385,514 tons. The Republic of Serbia has favorable conditions for growing soybean. The correct cultivation practices and choice variety is a prerequisite for economic profitable soybean production.Površine pod sojom u svetu, u 2013. godini iznosile su 111,27 miliona ha, sa ostvarenom ukupnom proizvodnjom od 276,40 miliona tona. Amerika je najveći svetski proizvođač soje, sa površinama od 85,63 miliona ha, odnosno sa ukupnim svetskim učešćem od 76,95%, zatim slede, Azija sa površinama od 20,69 miliona ha i Evropa sa površinama od 3,18 miliona ha i ukupnom proizvodnjom od 5,94 miliona tona.

Republika Srbija ima povoljne uslove za gajenje soje. Pravilna tehnologija gajenja i odabir sorte preduslov je za ekonomski isplativu proizvodnju soje

Uticaj količine i oblika azota na produktivnost ozime pšenice

This paper examined the influence of the quantity and form of nitrogen on the important parameters of productivity of winter wheat. Field microexperiments were conducted in agroecological conditions of Central Serbia and loam soil type (vertisol). The results showed significant differences in the spike length, number of spikelets, grain yield and hectoliter weight between examined quantities of nitrogen. On the contrary, a form of nitrogen had not a significant effect on the observed parameters of productivity of wheat.U ovom radu je ispitivan uticaj količine i oblika azota na važnije parametre produktivnosti ozime pšenice. Poljski mikroogled je postavljen u agroekološkim uslovima centralne Srbije i na zemljištu tipa smonica (vertisol). Dobijeni rezultati su pokazali značajne razlike u dužini klasa, broju klasića, prinosu zrna i hektolitarskoj masi između ispitivanih količina azota. Suprotno tome, oblik azota nije ispoljio značajan uticaj na posmatrane parametre produktivnosti pšenice

Pregled lekovitih biljnih taksona razdela Magnoliophyta na lokalitetu Košutnjak

This work provides a description off collected herbal types that according to their taxonomy belong to the Magnoliophyta division on the locality of Košutnjak (Belgrade). It is determined a significant diverse flora of medicinal herbs. A biological material is collected in a herbarium and it is determined by the keys for plant identification. A treatment effect of medicinal herbs is based on pharmacological active components that mostly belong to a group of secondary metabolites.U ovom radu, dat je prikaz sakupljenih biljnih vrsta, koje taksonomski pripadaju razdelu Magnoliophyta, na lokalitetu Košutnjak (Beograd). Primećen je značajan diverzitet flore lekovitih biljaka. Biološki materijal je herbarizovan i determinisan pomoću ključeva za determinaciju biljaka. Terapijsko dejstvo lekovitog bilja, zasniva se na farmakološki aktivnim sastojcima, koji uglavnom pripadaju grupi sekundarnih metabolita

Brojnost i značaj aktinomiceta u zemljištu u fazi fiziološke zrelosti zrna kukuruza (Zea mays L.)

In this work, it is determined the number of actinomycetes, a very diverse order of microorganisms, which take part in the transformation of the soil organic matter depending on the soil type, the quantity of applied N and the way of the soil treating. The stage of physiological corn kernel maturity shows the higher number of actinomycetes in "cernozem" under the sown maize as well as a stimulating effect of nitrogen.U ovom radu, određena je brojnost aktinomiceta, veoma raznovrsne grupe mikroorganizama, koja učestvuje u transformaciji zemljišne organske materije, u zavisnosti od tipa zemljišta, količine primenjenog azotnog (N) đubriva i načina obrade zemljišta. U fazi fiziološke zrelosti zrna kukuruza, utvrđena je veća brojnost aktinomiceta u černozemu, pod usevom kukuruza, kao i stimulativni efekat azota

Elective cancer surgery in COVID-19-free surgical pathways during the SARS-CoV-2 pandemic: An international, multicenter, comparative cohort study

PURPOSE As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19–free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway. PATIENTS AND METHODS This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer types without preoperative suspicion of SARS-CoV-2. Participating hospitals included patients from local emergence of SARS-CoV-2 until April 19, 2020. At the time of surgery, hospitals were defined as having a COVID-19–free surgical pathway (complete segregation of the operating theater, critical care, and inpatient ward areas) or no defined pathway (incomplete or no segregation, areas shared with patients with COVID-19). The primary outcome was 30-day postoperative pulmonary complications (pneumonia, acute respiratory distress syndrome, unexpected ventilation). RESULTS Of 9,171 patients from 447 hospitals in 55 countries, 2,481 were operated on in COVID-19–free surgical pathways. Patients who underwent surgery within COVID-19–free surgical pathways were younger with fewer comorbidities than those in hospitals with no defined pathway but with similar proportions of major surgery. After adjustment, pulmonary complication rates were lower with COVID-19–free surgical pathways (2.2% v 4.9%; adjusted odds ratio [aOR], 0.62; 95% CI, 0.44 to 0.86). This was consistent in sensitivity analyses for low-risk patients (American Society of Anesthesiologists grade 1/2), propensity score–matched models, and patients with negative SARS-CoV-2 preoperative tests. The postoperative SARS-CoV-2 infection rate was also lower in COVID-19–free surgical pathways (2.1% v 3.6%; aOR, 0.53; 95% CI, 0.36 to 0.76). CONCLUSION Within available resources, dedicated COVID-19–free surgical pathways should be established to provide safe elective cancer surgery during current and before future SARS-CoV-2 outbreaks

Functional electrical stimulation of the facial muscles to improve symptoms in individuals with major depressive disorder: pilot feasibility study

Abstract Background Currently, the mainstay of treatment in patients diagnosed with major depressive disorder (MDD) requiring medical attention is second generation anti-depressants. However, about 40% of patients treated with second-generation anti-depressants do not respond to initial treatment and approximately 70% do not achieve remission during the first-step treatment. There are a few non-pharmacological options available, but none have shown consistently positive results. There is a need for an intervention that is relatively easy to administer, produces consistently positive results and is associated with minimal side effects. In the current study, we assessed the feasibility of using transcutaneous Functional Electrical Stimulation Therapy (FEST) of the facial muscles, as a tool for improving depressive symptoms in individuals with MDD. Results Ten (10) individuals with moderate to severe MDD received three FEST sessions/week for a minimum of 10 to a maximum of 40 sessions. All study participants completed the required 10 therapy sessions, and 5 of the 10 participants completed additional 30 (totalling 40) FEST sessions. There were no adverse events or concerns regarding compliance to therapy. We found statistically significant improvements on Hamilton Rating Scale for Depression (HDS) and Inventory of Depressive Symptomatology (IDS) measures. However, no significant improvements were found on Positive and Negative Affect Scale and 10-point Visual Analogue Scale scales. Participants reported improvements in sleeping patterns, and this correlated with statistically significant improvements on sleep parameters of HDS and IDS measures. Conclusion This study indicates that facial FEST is an acceptable, practical, and safe treatment in individuals with MDD. We provide preliminary evidence to show improvements in depressive symptoms following a minimum of 10 FEST sessions
