Research The Chopper Apparatus Of Equipment For Chopping Pressed Rough Fodders, Sh.H. Gapparov, N.A. Ashurov

Irrigation and Melioration

Livestock is one of the most important agricultural sectors in Uzbekistan and it is based on family livestock farms. On family farms, livestock animals are fed with pressed roughage, including corn stalks, alfalfa hay, barbed straw and wheat straw, mixed with concentrated feed. However, due to the lack of small choppers suitable for small farms, the compressed feed is fed to animals without chopping, as a result of which about 25-30 percent of them go to waste and there are large losses. Taking this into account, a small device was developed for chopping pressed roughage and mixing it with concentrated …

Henry M. Rowan College of Engineering Departmental Research

Whether resurfacing or not resurfacing the patella during total knee arthroplasty (TKA) still is a challenge to orthopedic surgeons. A significant reason for this controversy is the far from perfect outcomes of both techniques, resulting from inadequate knowledge of normal patellar dimensions in a diseased one. The primary purpose of the current study is to find the pre-diseased patellar dimensions and the ethnic differences in patellar dimensions. We measured the patella's dimensions on 927 normal young adult knee MRIs from seven different ethnicities. Besides comparing the dimensions between sexes, ages, and sides, we analyzed the differences among ethnic groups. The …

Incorporating Pacific Ocean Climate Information To Enhance The Tree-Ring Based Streamflow Reconstruction Skill, Saria Bukhary, Ajay Kalra, Sajjad Ahmad

Civil and Environmental Engineering and Construction Faculty Research

The Sacramento River Basin (SRB) and the San Joaquin River Basin (JRB) have a history of recurring droughts. Both are important for California, being the crucial source of water supply. The available instrumental records may not depict the long-term hydrologic variability encompassing the duration and frequency of the historic low flow events. Thus, streamflow reconstruction becomes important in the current scenario of climatic alteration, escalating population and growing water needs. Studies have shown that Pacific Decadal Oscillation (PDO), Southern Oscillation Index (SOI), and Pacific Ocean sea surface temperature (SST) influence the precipitation and streamflow volumes of southwestern United States, particularly …

Journal of Electrochemistry

Decorating TiO2 nanotube arrays with RGO to improve the photocatalytic activity of TiO2 nanotube arrays has been reported. For the reported RGO-TiO2 nanotube arrays, TiO2 nanotube arrays were prepared by anodizing the high-purity Ti foil in an organic electrolyte for multiple-step treatments, while RGO were deposited on TiO2 nanotube arrays by using cyclic voltammetry or other electrical reduction methods. To enhance the reduction degree and the coverage of RGO on the resultant RGO-TiO2 nanotube arrays, in this work, the one-step electrochemical anodization in hydrofluoric acid was used to fabricate TiO2 nanotube arrays with …


Preparation And Process Optimization Of Cathode Materials For Lithium-Sulfur Batteries, Kai Wu Dec 2020

Preparation And Process Optimization Of Cathode Materials For Lithium-Sulfur Batteries, Kai Wu

Journal of Electrochemistry

Lithium-sulfur (Li-S) batteries represent promising candidates for next-generation energy storage system due to their high energy density and low material cost. However, the industrial application of Li-S batteries remains challenges because of the shuttle effect from lithium polysulfides and the lack of facial routes for Li-S battery preparation. To solve these problems, a cathode consisting of different commercial carbon materials, namely, acetylene black (SP), Ketjen Black (KB) and carbon nanotube (CNT), with sulfur (S) is prepared separately for Li-S battery. After the process of 8-h ball milling for KB/S composite, together with the polyvinyl pyrrolidone (PVP) binder, the cathode could …

Diverse And Complex Muscle Spindle Afferent Firing Properties Emerge From Multiscale Muscle Mechanics, Kyle P. Blum, Kenneth S. Campbell, Brian C. Horslen, Paul Nardelli, Stephen N. Housley, Timothy C. Cope, Lena H. Ting

Physiology Faculty Publications

Despite decades of research, we lack a mechanistic framework capable of predicting how movement-related signals are transformed into the diversity of muscle spindle afferent firing patterns observed experimentally, particularly in naturalistic behaviors. Here, a biophysical model demonstrates that well-known firing characteristics of mammalian muscle spindle Ia afferents – including movement history dependence, and nonlinear scaling with muscle stretch velocity – emerge from first principles of muscle contractile mechanics. Further, mechanical interactions of the muscle spindle with muscle-tendon dynamics reveal how motor commands to the muscle (alpha drive) versus muscle spindle (gamma drive) can cause highly variable and complex activity during …

Superior Polyaniline Cathode Material With Enhanced Capacity For Ammonium Ion Storage, Shelton Farai Kuchena, Ying Wang

Faculty Publications

A paradigm shift in aqueous rechargeable batteries has seen the development of nonmetal ammonium ions (NH4+) as charge carriers. NH44+ ions have a molecular weight of 18 g mol-1 and hydrated ionic size of 3.31 Å, which are smaller than those of metal ions, leading to faster kinetics during charge transfer. Yet few electrode materials have been studied for this type of battery. This work is the first effort to show that polyaniline (PANI) is an excellent material for NH4+ ion storage, and thus further proves that NH4+ ions can be used as effective charge carriers in aqueous ion battery …
