Local adaptation within and among populations may have an impact on processes ranging from speciation to the evolution of mixed breeding systems and dispersal strategies. It is also one potential factor that could favor the production of asexual over sexual propagules. This field experiment tested whether asexually produced bulbils of Allium vineale demonstrate local adaptation to the parental ...

Dry seeds of many orchid species, when stored at low temperatures, are capable of maintaining high levels of viability for many years, supporting orchid seed banking as a valuable part of emerging integrated conservation strategies. The Orchid Seed Science and Sustainable Use (OSSSU) network has already stored over 300+ species across 26 countries around the world. Its future ambition to store ...

Selection of plant species, their varieties or hybrids and the formation productivity is an urgent need today due to shortage biofuel production at world level. The purpose research was reveal influence technological measures (row spacing density standing) on elements crop structure castor varieties. Research conducted during 2020-2021in field conditions study stand row width Khortytska 3 Olesi...

DNA molecular weight standard control, also called DNA marker (ladder), has been widely used in the experiments of molecular biology. In the paper, we report a method by which DNA marker was prepared based on multiple PCR technique. 100-1000 bp DNA fragments were amplified using the primers designed according to the 6631 ~ 7630 position of lambda DNA. Target DNA fragments were amplified using T...

Gudalur Adivasi Hospital provides inand outpatient services to four main tribal (Adivasi) populations – Paniya, Bettakurumba, Mullakurumba and Kattunaikan – in a remote part of the Gudalur District, Tamil Nadu, India. It is classified as 'backward' by the Indian government. According to the 2011 census, Gudalur had a population of 49 535, with 1032 females for every 1000 males, much higher than...

All singleton live births occurring in Singapore in the three years 1981-3 were computed, and birthweight was examined in the different ethnic groups (Chinese, Malay, and Indian). Overall the proportions of babies of very low birthweight (less than 1500 g) and low birthweight (less than 2500 g) were: Chinese 0.3% and 6.1%, Malays 0.4% and 8.5%, and Indians 0.5% and 10.0%. The important finding ...

Genetic improvements have significantly contributed to wheat production. Five wheat cultivars-widely grown in north China in the 1950s, 1990s, or 2010s-were grown in field experiments conducted in the 2014-2015 and 2015-2016 growing seasons. This study evaluated the genetic progress in wheat grain yield and its related traits in north China and explored how breeding and selection have influence...

Winter rapeseed (Brassica napus L.) has potential to become an alternate oilseed crop both for edible oil production and energy agriculture (biofuel production) for Turkey. This study was conducted to determine the effect of year, N sources and doses on the yield and quality traits of winter rapeseed in a cereal system in calcareous soils over two seasons, 2000-2001 and 2001-2002, in Central An...

OBJECTIVE To compare the outcomes of twin pregnancies conceived by artificial reproductive techniques (ART) with those of spontaneous conception. STUDY DESIGN In this multicenter prospective trial, comparisons were made between methods of conception in twin pregnancies, for maternal and perinatal outcomes. RESULTS Of 1001 twin pairs, 763/1001 (72.7%) were spontaneously conceived and 238/100...

We conducted a large retrospective study to investigate the confounding factors that predict Ce ROC under propofol-based TIVA with TCI. We recorded sex, age, height, weight, Ce LOC, Ce ROC, total propofol and fentanyl consumption dose, and anesthetic time. Simple linear regression models were used to identify potential predictors of Ce ROC, and multiple linear regression models were used to ide...
