The present experiment was conducted in the Department of Fruit Science, College Horticulture and Forestry, Pasighat, Arunachal Pradesh, during year 2021-2022. trial laid out using two factorial RBD replicated thrice. Assam lemon trees were pruned at 25% (P1), 50% (P2) from top apex soil drenching with Pseudomonas fluorescens @ 90g/plant (B1), Trichoderma (B2), Azotobacter 15g/plant (B3) a comb...
Biochar produced from transforming bioresource waste can benefit sustainable agriculture and support circular bioeconomy. The objective of this study was to evaluate the effect application biochar, wheat straws, a nitrification inhibitor, sourced neem (Azadirachta indica), in combinition with recommended synthetic fertilizer on soil properties, maize (Zea mays L.) plant growth characteristics, ...
تبدیل هیدرازونوآمیدن های حلقوی به مشتقات آمینوپیرازولو مربوطه سپس حلقه زایی بین گروههای آمینوپیرازول و nh آمیدین حلقوی منجر به ایجاد سیستم های حلقوی: 8و9- دی هیدرو- h7- پیرازولو ]1،5-c [ پیریمیدو ]1،2-[a ]1،3،5[ تری آزین-3- ایل سیانیدو .... (5-8) می شوند. پیرازولوپیریمیدو تری آزین از 2- هیدروزین پیریمیدنهایی تهیه شده اند که آنها نیز به سهولت از آمونولیز 2-متیل تیوپیریمیدین (1a,1b) سنتز شده اند ...
this paper proposes a new configuration for solar energy conversion systems. one challenging issue of the photovoltaic (pv) systems is partial shading, and in this paper module integrated converters (mic) are used to overcome this problem in pv arrays. a few boost converters are employed as mics to mitigate the shading effect. furthermore, to reduce the cost and to increase the system performan...
Molecular mimicry between viral antigens and host proteins was often suggested to be involved in induction of autoimmune diseases. In type 1 diabetes where pancreatic beta cells are destroyed by autoimmune phenomena, a linear sequence homology between a major autoantigen, glutamate decarboxylase (GAD), and the 2C protein of coxsackie B4 was identified. In addition, a sequence homology between G...
CHRNA5-A3-B4 variants, rs16969968, rs588765 and rs578776, are consistently associated with tobacco consumption among smokers, but the association with smoking cessation is less consistent. Among the studies that reported significant associations with cessation, the effects were observed in smokers treated with placebo treatment in some studies and conversely in those receiving active pharmacolo...
Background: The pH and voltage-regulated Slo3 K channel, a homologue of the Caand voltage-regulated Slo1 K channel, is thought to be primarily expressed in sperm, but the properties of Slo3 studied in heterologous systems differ somewhat from the native sperm KSper pH-regulated current. There is the possibility that critical partners that regulate Slo3 function remain unidentified. The extensiv...
The gas-phase structures of the protonated pentapeptide Leu-enkephalin and its main collision-induced dissociation (CID) product ions, b4 and a4, are investigated by means of infrared multiple-photon dissociation (IR-MPD) spectroscopy and detailed molecular mechanics and density functional theory (DFT) calculations. Our combined experimental and theoretical approach allows accurate structural p...
در این مقاله یک مبدل افزاینده سوئیچینگ، فلای بک جدید ارائه گردیده است. در ابتدا مبدل به صورت سخت کلید زنی می شود که در این حالت به صورت کامل تحلیل شده است. سپس مدار کمکی جهت نرم کردن کلیدزنی کلید اصلی آن به مبدل اضافه شده است که مدار کمکی در این مبدل نه تنها شرایط سوئیچینگ نرم را برای کلید اصلی مبدل فراهم می سازد بلکه از جهش های ولتاژ دو سر کلید اصلی در هنگام خاموش شدن در اثر سلف نشتی ترانسفورم...
In this section we shall assume that all algebras are finite dimensional algebras over an algebraically closed field F. The fact that F is algebraically closed is only for convenience, to avoid the division rings that could arise in the decomposition of Ā just before (4.8) below. Let A ⊆ B be an inclusion of algebras. Then B⊗F B is an (A,A)-bimodule where A acts on the left by left multiplicati...
