sainfoin (onobrychis viciifolia scop.) is a perennial forage legume has recognized for its feed value and high stability. this experiment was conducted to investigate the relationship among morphological and agronomic traits using multivariate statistical methods including correlation, regression and factor analysis. twenty one accessions of sainfoin were evaluated in a randomized complete bloc...
Abstract—A compact dual-band power divider for GSM/DCS applications is proposed in this letter. Novel planar artificial transmission lines are applied to miniaturize the power divider and achieve wideband response. The proposed dual-band power divider is about 37% of conventional one. The design principle, simulated and measured results are all discussed. The measured results show that good per...
OBJECTIVE To simplify body weight measurement and, particularly, to encourage children and their parents to participate in the Italian nutritional surveillance system OKkio alla SALUTE, children were measured with clothes and then the weight was corrected for the estimated weight of the clothes. In the present study we compared the children's weight measured in underwear, as recommended by the ...
A 3-year entomological study was carried out on the transmission of malaria in a village of 900 inhabitants in a rice-growing area of Burkina Faso. In the study area inhabitants use bed nets to protect themselves from mosquito bites. In the first year of the study, baseline data were collected; in the second year, the village was divided in two parts and all the bed nets in the southern part we...
Poverty alleviation is a major indicator to decide whether economic growth is of benefit to the poor in a society. This study therefore addressed the extent of non-income poverty alleviation between 1999 and 2008, using the Demographic and Health Survey (DHS) data. The fuzzy method and two stage least square approaches were used to analyze the data. The results show that between 1999 and 2003, ...
BACKGROUND Bevacizumab and the antimetabolites capecitabine and gemcitabine have been shown to improve outcomes when added to taxanes in patients with metastatic breast cancer. The primary aims of this trial were to determine whether the addition of capecitabine or gemcitabine to neoadjuvant chemotherapy with docetaxel, followed by doxorubicin plus cyclophosphamide, would increase the rates of ...
A continuous record of atmospheric lead since 12,370 carbon-14 years before the present (14C yr BP) is preserved in a Swiss peat bog. Enhanced fluxes caused by climate changes reached their maxima 10, 590 (14)C yr BP (Younger Dryas) and 8230 (14)C yr BP. Soil erosion caused by forest clearing and agricultural tillage increased lead deposition after 5320 (14)C yr BP. Increasing lead/scandium and...
The light-dependent kinetics of the apparent in vivo synthesis and degradation of 2-carboxyarabinitol 1-phosphate (CA1P) were studied in three species of higher plants which differ in the extent to which this compound is involved in the light-dependent regulation of ribulose-1,5-bisphosphate carboxylase (Rubisco) activity. Detailed studies with Phaseolus vulgaris indicate that both the degradat...
Rice (Oryza sativa) is a vital staple food crop in more than 60 percent of the world, and around 430 million metric tons rice are consumed worldwide. Moreover, to reduce synthetic fertilizer use while keeping production on track, researchers decided conduct study Kappaphycus drippings (K.D.) foliar at Brgy. Mangayon, Compostela, Davao de Oro from July December 2019 determine effects different r...
An intact method for measuring immediately linear rates of acetylene reduction was used to investigate the relationship between temperature, pH, O(2) concentration, and light intensity with the rate of root-associated nitrogenase activity in rice (Oryza sativa L.). Nitrogenase activity varied over a temperature range of 10 to 50 degrees C and optimal rates of acetylene reduction were recorded a...
