background one of the most painful experiences of women in life is labor. the use of non-drug methods for pain relief is on the increase. this study aimed to compare mono-stage and bi-stage acupressure at sp6 point on the severity of labor pain and the delivery outcome. methods this is a quasi-experimental single blind study from december 2010 to june 2011 in which 150 term pregnant women in la...

The effects of varying photophase conditions on biological parameters of Mahanarva fimbriolata (Stal) (Hemiptera: Cercopidae), nymphs and adults were evaluated. Eggs of a late developmental stage were placed near sugarcane roots (cultivar RB739735) maintained in a greenhouse (21 ± 7 °C, 90 ± 10% RH). Nymphs and adults were exposed to the following photophase conditions: (a) 13:11 L:D as nymphs ...

Abstract Background The fall armyworm Spodoptera frugiperda is a highly destructive agricultural pest that primarily damages maize in China. However, there were no reports of S. damage to banana until it was observed on bananas the wild. This suggested crops may be potential hosts pest. To clarify fitness and impact banana, this study analysed survival development fed laboratory constructed age...

Abstract This study aimed to confirm the causality of climatic and soil physical factors on silage corn yield based climatesoil-yield network in Korea. The variables were growing degree days, high temperature, low surface rainfall, relative humidity, wind speed, sunshine duration before after silking. effective depth, slope drainage class soil. total digestible nutrients, dry matter fresh yield...

Assisted reproductive technology is used for treating infertility, and its success relies on the quality viability of embryos chosen uterine transfer. Currently, embryologists manually assess embryo development, including time duration between cell cleavages. This paper introduces a machine learning methodology automating computations start cleavage stages, in hours post insemination, time-laps...

The safety of human exposure to an ever-increasing number and diversity of electromagnetic field (EMF) sources both at work and at home has become a public health issue. To date, many in vivo and in vitro studies have revealed that EMF exposure can alter cellular homeostasis, endocrine function, reproductive function, and fetal development in animal systems. Reproductive parameters reported to ...

Using a weak migration and weak mutation approximation, I studied the average waiting time to parapatric speciation. The description of reproductive isolation used is based on the classical Dobzhansky model and its recently proposed multilocus generalizations. The dynamics of parapatric speciation are modelled as a biased random walk performed by the average genetic distance between the residen...
