intercropping systems lead to reduce weeds population and their biomass. in order to study effect of marigold (calendula officinalis) and mungbean (vigna radiata) intercropping in different sowing times on yield and weeds control a factorial experiment based on randomized complete block design was performed in islamic azad university, tabriz branch, iran, during 2012 in three replications. stud...

The physiological equivalents of power output maintenance and recovery during repeated-sprint exercise (RSE) remain to be fully elucidated. In an attempt to improve our understanding of the determinants of RSE performance we therefore aimed to determine its recovery following exhaustive exercise (which affected intramuscular and neural factors) concomitantly with those of intramuscular concentr...

A model of a linear aerospike rocket nozzle that consists of coupled aerodynamic and structural analyses has been developed. A nonlinear computational fluid dynamics code is used to calculate the aerodynamic thrust, and a three-dimensional finite-element model is used to determine the structural response and weight. The model will be used to demonstrate multidisciplinary design optimization (MD...

Limpets are common inhabitants of the midlittoral and upper infralittoral zones play an important ecological role in coastal ecosystem. The study aimed to assess growth, meat yield, morphological aspects, condition reproduction features Patella caerulea . About 58% collected Mediterranean limpets were concentrated 25.0-34.9 mm shell length group. average yield ratio was calculated as 39.34%. Me...

This study explores the effects of pipe wall properties (thermal conductivity k and thickness tw) on heat transfer performance a rectangular thermosyphon with phase change material (PCM) suspension geometric configuration (aspect ratio = 1; dimensionless heating section length 0.8; relative elevation between cooling sections 2) that ensures optimum efficiency in section. The following parameter...

A comparative study of testicular biometry was done in rams using three major breeds of sheep in Nigeria. Biometrical parameters observed were scrotal circumference (SC), testes weight (TW), testes length (TL), tunica albuginea weight (TAW), testes volume (TV), testes density (TD), epididymal weight (EW), epididymal length (EL), caput (CA), corpus (CO), cauda weight (CU), epididymal volume (EV)...

The Italian Ministry of University and Research (MIUR) funded the HYPROB Program to develop regeneratively cooled liquid rocket engines. In this type engine, propellant oxygen–methane is used, allowing us reach very good performances in terms high vacuum specific impulse thrust-to-weight ratio. present study focused on final ground demonstrator, which will be able produce a 30 kN thrust flight ...

There are many classical problems in P whose time complexities have not been improved over the past decades. Recent studies of “Hardness in P” have revealed that, for several of such problems, the current fastest algorithm is the best possible under some complexity assumptions. To bypass this difficulty, Fomin et al. (SODA 2017) introduced the concept of fully polynomial FPT algorithms. For a p...

In this study, eight promising advanced bread wheat genotypes derived from breeding programs and Ceyhan-99, Sagittario, Masaccio, Seri-82 commercial cultivars were used as materials. The experiments carried out in 2018-2019 2019-2020 cropping years a randomized complete block design with four replications. the some agronomic quality traits investigated. Bread varied significantly for all invest...

Tumor necrosis factor-alpha (TNF) binds to two receptors: TNFR1/p55-cytotoxic and TNFR2/p75-pro-survival. We have shown that tumor growth in p75 knockout (KO) mice was decreased more than 2-fold in Lewis lung carcinoma (LLCs). We hypothesized that selective blocking of TNFR2/p75 LLCs may sensitize them to TNF-induced apoptosis and affect the tumor growth. We implanted intact and p75 knockdown (...
