BACKGROUND: Nowadays total hip arthroplasty (THA) is the method of choice for treatment late stages osteonecrosis femoral head (OFH) and osteoarthritis (OA) joint.
 OBJECTIVE: To evaluate efficacy complication pattern THA in OFH OA.
 MATERIALS AND METHODS: The study included 74 patients who underwent primary OA IIIIV (Kellgren Lawrence classification) (ARCO classification). Group 1 34...

Ammonia (NH3) emission from animal feeding operations (AFOs) has caused concerns on public health and environmental degradation, such as ecosystem acidification, eutrophication, and formation of PM2.5 fine particles. Current ammonia emission measurement methodologies are accurate and reliable, but time consuming, expensive, and impractical for most facilities. In the present study, an alternati...

* Corresponding author ([email protected]) Abstract: Antibiotic residues in animal waste from concentrated animal feeding operations are of considerable concern because of the potential development of antibiotic resistant bacteria in the environment and the effect of these residues on manure treatment systems. The objective of this study was to determine the effect of cefazolin (10 mg L) dur...

With approximately 696 million tons of animal manure produced yearly in the United States, and 46% of that being generated on concentrated animal feeding operations (CAFOs) (Ribaudo et al., 2003), animal waste management is becoming an important environmental concern. It causes air and water quality concerns and climate impacts. In addition, many CAFOs generate more waste than can be disposed o...

Most livestock and poultry odors are generated by the anaerobic decomposition of livestock wastes such as manure (feces and urine), spilled feed, bedding materials, and wash water. Increased organic loading rates due to expanding animal numbers, slug loading, concentrated waste streams, and/or inadequate amounts of dilution water increase the potential for odor emissions from waste management s...

Soil compactibility which basically depends on soil texture, organic matter and soil water content during farm machinery traf®cking are major factors affecting soil conservation. In a ®eld experiment, cattle farmyard manure was applied to a silty clay loam soil (®ne-loamy, mixed, thermic Typic Haplargids, USDA; Calcaric Cambisols, FAO) in Isfahan, Iran. Three rates, 0, 50, 100 Mg haÿ1 (on oven ...

This article addresses the effect of ultrasonication as a pretreatment to anaerobic digestion of four types of animal manure, including swine slurry, beef feedlot manure, dairy manure slurry, and separated dairy manure effluent. The effect of ultrasonication on soluble chemical oxygen demand (SCOD) and biochemical methane potential (BMP) were determined, and the energy efficiency of ultrasonic ...

An experiment was undertaken at the College of Agriculture, Vellayani, Kerala to study effect organic nutrition on growth attributes and yield taro during 2019-20 2020-21. The treatments comprised six levels sources (S1 - FYM + wood ash; S2 ash PGPR mix I; S3 I vermiwash; S4 Poultry manure S5 S6 vermiwash) two in-situ green manuring (G1 with cowpea; G2 dhaincha ) three controls (C1 Nutrient man...

We evaluated transmembrane potential changes at the ends of isolated rabbit ventricular myocytes during defibrillation-strength shocks given in the cellular refractory period. The myocytes were stimulated (S1 pulse) to produce an action potential. Then a constant-field shock (S2 pulse) with an electric field of 20 or 40 V/cm was given at an S1-S2 interval of 50 msec. The cells were stained with...

introduction energy and environmental issues are two common concerns of modern societies. fossil fuels consumption is believed to be the primary factor contributing to severe environmental problems, such as global warming, climate change and acid rain, which are a serious threat to the world’s ecosystems. in order to stabilize the earth’s climate and prevent further global warming, the earth re...
