Abstract. Nitrogen oxides (NOx= nitric oxide (NO) + nitrogen dioxide (NO2)) are important trace gases that affect atmospheric chemistry, air quality, and climate. Contemporary development of NOx emissions inventories is limited by the understanding roles vegetation (net source or net sink), vehicle from gasoline- diesel-powered vehicles, application emission control technologies, accurate verif...

Theobroma cacao is an economically important tropical-fruit tree where chocolate obtained, and it used as traditional medicine worldwide against several diseases. In the present study, in vivo model computational biology approaches were to elucidate potential mechanisms of T. in treatment diarrhea. The antidiarrheal intestinal motility activity was conducted using animal induce...

Cotton (Gossypium hirsutum L.) production in Oklahoma has more than tripled the last ten years. This increase cotton acreage Oklahoma, a region that traditionally produces winter wheat, led to increased incidences of 2,4 D contamination sprayers are used spray crops. is extremely sensitive D, with losses yield and ultimately profit producer cases drift or tank carryover. In this study, six cult...

Melatonin production in the pineal gland is high at night and low during the day. This rhythm reflects circadian changes in the activity of serotonin N-acetyltransferase [arylalkylamine N-acetyltransferase (AA-NAT); EC 2.3.1.87], the penultimate enzyme in melatonin synthesis. The rhythm is generated by an endogenous circadian clock. In the chick, a clock is located in the pinealocyte, which als...

Bronchial hyperresponsiveness (BHR) is a key feature of asthma and may be measured by direct methacholine challenge or indirect adenosine monophosphate (AMP) challenge. We performed a retrospective analysis of our database (n = 487) of patients with asthma with the aim first, to compare methacholine and AMP challenge as screening tools, and second, to identify any relationships between BHR and ...

in this study, a three–layer artificial neural network (ann) model was developed to predict the pressure gradient in horizontal liquid–liquid separated flow. a total of 455 data points were collected from 13 data sources to develop the ann model. superficial velocities, viscosity ratio and density ratio of oil to water, and roughness and inner diameter of pipe were used as input parameters of t...

Abstract. Coastal lagoons are important sites for nitrogen (N) removal via sediment burial and denitrification. Blooms of heterocystous cyanobacteria may diminish N retention as dinitrogen (N2) fixation offsets atmospheric losses We measured N2 in the Curonian Lagoon, Europe's largest coastal lagoon, to better understand factors controlling context seasonal changes phytoplankton community compo...

Waste water expulsion containing toxic and hazardous ingredients from textile industry is one of the biggest concerns in this modern age. N-doped nano composites as an efficient catalyst are playing a significant role reducing toxicity that effluent. Ti-Mel capped Ag2S NCs (N-Ti-C/Ag2S NCs) TiO2 (TiO2/Ag2S were synthesized via calcinations at 700°C, whereas was prepared by simple hydrothermal t...

This paper presents a description of the principal aspects employed in the development of a speaker verification system based on a Spanish corpus. The main goal is to obtain classification results and behavior using Support Vector Machines (SVM) as the classifier technique. The most relevant aspects involved in developing a Spanish corpus are given. For the front end processing a novel method t...
