Genotype, environmental temperature, and agronomic management of parents influence seed yield in three-way cross hybrid maize production. The objective this research was to generate information on the production six hybrids their progenitors, adapted tropical lowlands. Data days to—and duration of—flowering, distance spike stigmas, five female single crosses male inbred lines were recorded for ...
El Niño and La Niña Southern Oscillation (ENSO) are major drivers that affect climatic variables in many countries. Therefore, ENSO mediated variation factors have significant consequences for crop production. We studied variations temperature rainfall the five coastal districts of Bangladesh during 1951–2017, impacts on crops production were analyzed using growing degree day (GDD) index. Stati...
Bu çalışma dallı darı çeşitlerinin farklı sulama seviyelerinde biyokütle verimi ve bazı gelişme dönemleri için gerekli olan gün ile bitki büyüme derece (GDD) değerlerinin belirlenmesi amacı 2015 yılında tesis edilen alanda verim diğer tarımsal özelliklerin potansiyelinin tam olarak göründüğü 4.yıl verileri (2018 yılı) dikkate alınarak Konya ekolojik koşullarında yürütülmüştür. Tesadüf blokların...
یکی از اهداف مهم در زراعت چغندرقند، افزایش قدرت جوانهزنی و استقرار بوته در شرایط کمبود رطوبتی خاک میباشد. در این تحقیق آبیاری بوتههای تولید کننده بذری پس از دریافت 750، 1000 ، 1250 و 1500 درجه_ روز رشد (gdd) از زمان کاشت ریشه متوقف شد و بذرها در شرایط تنش خشکی تشکیل و رشد یافتند. آزمایش در قالب طرح بلوک کامل تصادفی با چهار تیمار و در چهار تکرار انجام شد. در زمان برداشت صفات کمی شامل عملکرد ب...
Abstract Background Autism Spectrum Disorder (ASD) is a developmental disorder characterized by deficits in social interaction/communication, restricted interests and repetitive behaviours. Recent discussions have emerged worldwide regarding possible “overly-inclusive” diagnosis of ASD, adding heterogeneity around presentation/etiology comorbidities. Objectives This study aimed to determine the...
Hand-held mobile computers have the potential to become important communication tools for roaming users. As such, they will also become very personal. They will be used under a wide range of operating conditions, and tight user control will be enforced on issues like power consumption, consistency control, and trust management. Their ability to adapt will be the key to their success. In this pa...
DIAGNOSTIC REASONING AND PLANNING IN EXPLORATORY CORRECTIVE DOMAINS Ron Rymon Bonnie L Webber Supervisor I have developed a methodology for knowledge representation and reasoning for agents working in exploratory corrective domains Working within the eld of Arti cial Intelligence in Medicine I used the speci c problem of diagnosis and repair in multiple trauma management as both motivation and ...
We report on the first femtosecond vertical external cavity surface emitting laser (VECSEL) exceeding 1 W of average output power. The VECSEL is optically pumped, based on self-assembled InAs quantum dot (QD) gain layers, cooled efficiently using a thin disk geometry and passively modelocked with a fast quantum dot semiconductor saturable absorber mirror (SESAM). We developed a novel gain struc...
In this paper we present a framework for modelling potential species distribution (PSD) of balsam fir [bF; Abies balsamea (L.) Mill.] as a function of landscape-level descriptions of: (i) growing degree days (GDD: a temperature related index), (ii) landsurface wetness, (iii) incident photosynthetically active radiation (PAR), and (iv) tree habitat suitability. GDD and land-surface wetness are d...
This study addresses relationships between leaf phenology, xylogenesis, and functional xylem anatomy in two ring-porous oak species, the temperate Quercus robur and the sub-Mediterranean Q. pyrenaica. Earlywood vessel (EV) formation and leaf phenology were monitored in 2012 and 2013. Ten individuals per species were sampled at each of three sites located in NW Iberian Peninsula. EV areas measur...
