Suzbijanje korova kod sirka

Diversifying the use of agricultural products, in addition to human and animal nutrition, higher profitability per unit of arable land can be achieved. Thanks to its origin and biological properties, sorghum is a crop that can significantly contribute to this diversification in the global plant production system. Due to C4 metabolism, high biomass production and pronounced tolerance to stress caused by adverse environmental conditions (drought, high temperatures), in the light of global climate change, sorghum is globally one of the five most cultivated cereals, which is increasingly finding its place in the European plant production system. In agronomic practice weeds are recognized as one of the most significant limiting factors in increasing productivity and quality. The aim of this paper is to review weed impact on sorghum plants and yield, as well as contemporary management approaches with reference to the latest trends aimed at optimizing the integrated weed protection of sorghum.Širenjem upotrebe poljoprivrednih proizvoda, pored korišćenja u ishrani ljudi i životinja, može se postići veća rentabilnost po jedinici obradive površine. Zahvaljujući svom poreklu i biološkim svojstvima, sirak je biljna vrsta koja u globalnom sistemu biline proizvodnje može značajno doprineti širenju upotrebe poljoprivrednih proizvoda. Usled C4 metabolizma, velike proizvodnje biomase i izražene tolerancije prema stresu izazvanom nepovoljnim uslovima spoljne sredine (suša, visoke temperature), sirak je sa aspekta globalnih klimatskih promena jedna od pet najviše gajenih žitarica u svetu. U poslednje vreme sve više nalazi svoje mesto i u sistemu biljne proizvodnje u Evropi. Korovi su u agronomskoj praksi prepoznati kao jedan od najznačajnijih ograničavajućih faktora povećanja produktivnosti i kvaliteta. Cilj ovog rada je da se da pregled uticaja korova na biljke i prinos sirka, kao i da se predstave savremeni tehnološki pristupi suzbijanja korova, sa osvrtom na najnovije trendove optimizacije integralne zaštite

Modified GIANT Dynamic Bandwidth Allocation Algorithm of NG-PON

Gigabit passive optical networks have been widely deployed due to the fact that the cost of their implementation is still decreasing. What is more important, we are facing theproblem with increasing demands on the transmission bandwidth. Regarding this issue, the ITU develops another two standards supporting higher downstream bitrate. The XG-PON standard is the first platform under the developing, and the NG-PON2 is the second standard. The first one provides compatibility and increases the downstream capacity of 10 Gbit/s and the second standard has the same assumptions, but does not have backward compatibility. In this article, we discuss only XG-PON networks. We choose amendment as the dynamic bandwidth allocation algorithms, and we have compared it with the original specification and with our modification. The primary intention of that modification is to reduce the delay of Triple Play (data, video, and voice) services. These services are represented by TCONT (Transmission Container), which is used to improve the PON system upstream bandwidth allocation and transmission status dynamically. As NS-3 simulator does not support the direct mapping of Triple Play services into T-CONT and their labeling. We focus on a delay value for Triple Play services which was reduced by own modification in a GIANT algorithm. On the other hand, we cannot reduce the delay value for VoIP services because it has the highest priority by T-CONT

Ancient human genomes and environmental DNA from the cement attaching 2,000 year-old head lice nits

Over the past few decades there has been an increased demand for genome analysis of ancient human remains. Destructive sampling is increasingly difficult for ethical reasons, and previous methods of breaking the skull to access the petrous bone are often forbidden for curatorial reasons, together with teeth which may be missing or too precious to sample. However, most ancient humans carried head lice, and their eggs abound in historical hair specimens. Here we show that host DNA is protected by the cement that glues head lice eggs (nits) to the hair of ancient Argentinian mummies, 1,500–2,000 years old. The cement also preserves ancient environmental DNA of the skin, including the earliest recorded case of Merkel Cell Polyomavirus. We also show that human DNA obtained from nit cement can equal human genome assessment from tooth DNA, can increase assessment from petrous bone by two-fold, and by four-fold DNA over bloodmeal of adult lice a millennium younger. Genome-wide analyses from nit cement DNA also enables identification of the population genetic affinities of ancient humans. In metric studies of the sheaths, the length of the cement tube negatively correlated with the age of the specimens, while hair linear distance between nit and scalp informed about environmental conditions at the time before death. Ectoparasitic lice sheaths on hair, feathers, skins, or mummified remains can offer an alternative, non-destructive source of high-quality ancient DNA from a variety of host taxa and reveal details of their historical environment

Early divergent strains of Yersinia pestis in Eurasia 5,000 years ago.

The bacteria Yersinia pestis is the etiological agent of plague and has caused human pandemics with millions of deaths in historic times. How and when it originated remains contentious. Here, we report the oldest direct evidence of Yersinia pestis identified by ancient DNA in human teeth from Asia and Europe dating from 2,800 to 5,000 years ago. By sequencing the genomes, we find that these ancient plague strains are basal to all known Yersinia pestis. We find the origins of the Yersinia pestis lineage to be at least two times older than previous estimates. We also identify a temporal sequence of genetic changes that lead to increased virulence and the emergence of the bubonic plague. Our results show that plague infection was endemic in the human populations of Eurasia at least 3,000 years before any historical recordings of pandemics

The population history of northeastern Siberia since the Pleistocene.

Northeastern Siberia has been inhabited by humans for more than 40,000 years but its deep population history remains poorly understood. Here we investigate the late Pleistocene population history of northeastern Siberia through analyses of 34 newly recovered ancient genomes that date to between 31,000 and 600 years ago. We document complex population dynamics during this period, including at least three major migration events: an initial peopling by a previously unknown Palaeolithic population of 'Ancient North Siberians' who are distantly related to early West Eurasian hunter-gatherers; the arrival of East Asian-related peoples, which gave rise to 'Ancient Palaeo-Siberians' who are closely related to contemporary communities from far-northeastern Siberia (such as the Koryaks), as well as Native Americans; and a Holocene migration of other East Asian-related peoples, who we name 'Neo-Siberians', and from whom many contemporary Siberians are descended. Each of these population expansions largely replaced the earlier inhabitants, and ultimately generated the mosaic genetic make-up of contemporary peoples who inhabit a vast area across northern Eurasia and the Americas
