Experiments were conducted to examine soil nutrient dynamics under different farming systems and sources on maize yield. It was a split plot fitted into RCBD with three replicates. Main plots included two cropping (CS) (maize groundnut fallow): sub-plots; residue (GNR), (MZR), Cow dung (CD), pig manure (PGM); four composts; (PGM+MZR, PGM+GNR, CD+GNR CD+MZR) each at 5 t/ha; NPK 120 kg/ha, (Co) c...
The Processing Graph Method (PGM) technology is a paradigm that provides the engineer/system designer with an environment to specify and maintain applications in a form which is invariant over a wide range of MIMD message passing parallel architectures. We will give the reader the flavor of this approach by providing a description of an application; illustrating how that application is represen...
Homogenates of single individuals of two natural populations and five laboratory populations of Culex pipiens were examined by combining electrophoresis and heat denaturation studies on phosphoglucomutase (PGM). All populations showed a high degree of polymorphism for isoelectrophoretic temperature-resistant (tr) and temperature-sensitive (ts) alleles. Formal genetic data on the heat stability ...
Pt-group metal (PGM) electrocatalysts with unique electronic structures and irreplaceable comprehensive properties play crucial roles in electrocatalysis. Anion engineering can create a series of PGM compounds (such as RuP2, IrP2, PtP2, RuB2, Ru2B3, RuS2, etc.) that provide promising prospect for improving the electrocatalytic performance use noble metals. This review seeks electrochemical acti...
We have investigated the durability of a platinum group metal (PGM-)free Fe–N–C catalyst in which Fe sites are atomically dispersed (AD), and found it to be quite stable standard accelerated stress test (AST) cycles normally used for low-PGM catalysts: square wave with 0.6 V lower potential limit (LPL)—0.95 upper (UPL) 3-s holds at UPL LPL H 2 /N , 1.5 atm, 80 °C 100% RH. Considering metrics em...
Motivated by various applications in machine learning, the problem of minimizing a convex smooth loss function with trace norm regularization has received much attention lately. Currently, a popular method for solving such problem is the proximal gradient method (PGM), which is known to have a sublinear rate of convergence. In this paper, we show that for a large class of loss functions, the co...
ساخت روسازی های تقویت شده با مواد ژئوسنتتیک در پروژه هایی که بستر ضعیفی دارند و یا برای به تاخیر انداختن توسعه و انتشار ترک های لایه های آسفالتی قدیمی به لایه روکش و افزایش طول عمر روسازی در جاده های موجود ، گسترش یافته است . در این تحقیق پس از معرفی انواع ژئوسنتتیک ها ، به بررسی مکانیسم ایجاد ترک های انعکاسی و فرآیند اجرای محصولات ژئوسنتتیک با روکش آسفالتی پرداخته شده ، سپس با بررسی خرابی های ...
This research was aimed at evaluating the efficiency of advanced gravity and magnetic separations on the recovery of chromite from the fine Platinum Group Metals (PGM) tailings consisting of particles 80% passing 75 µm with about 45% being >45 µm resulting in high chromite losses. The PGM plant tailings were subjected to X-ray fluorescence, scanning electron microscopy and particle size dis...
Understanding user browsing behavior in web search is key to improving web search effectiveness. Many click models have been proposed to explain or predict user clicks on search engine results. They are based on the probabilistic graphical model (PGM) framework, in which user behavior is represented as a sequence of observable and hidden events. The PGM framework provides a mathematically solid...
A planar phase gradient metasurface (PGM) with gradients in two in-plane directions will introduce additional wave vectors to the reflected vector. For small incident angles, close normal vector, magnitude of vector is smaller than that and direction anomalous can be determined from components components. The expanded generalized Snell’s law, which includes diffraction order modes, combined arr...
