This study traces the causal effects of extreme weather events on nutritional and health outcomes among rural children in Uganda using four waves of individual child survey data (2009–2014). A simultaneous regression model was applied for causal inference while also accounting for households'...

Mines are a major source of contamination for aquatic environments. Lead and zinc mines are a primary source of environmental transition metal contamination resulting in major water contamination globally. In this study the use of biochar amended with wood ash (WAS) was evaluated as a treatment...

Zinc is an important nutrient for plant growth and development. Its availability is influenced by zinc solubilizing microbes (ZSM). Effects of commonly promoted agronomic practices on the abundance of ZSM are so far not well understood. In this study, we assessed the effects of farmyard manure...

Vineyards with a long history of cultivation in sandy and clayey soils, located in regions presenting subtropical climate, still lack studies associating Copper (Cu) and Zinc (Zn) fraction accumulation with distribution dynamics, as well as studies about the maximum adsorption capacities (MAC)...

For cost and safety reasons, aqueous batteries are suitable for large-scale energy storage. Among all aqueous batteries, the rechargeable aqueous zinc ion batteries (ZIBs) are promising choices owing to the low equilibrium potential and high volumetric capacity of zinc. However, its development...

As a new generation of electrode material, flexible electrode material can effectively broaden the application area and scope of energy storage devices. In this paper, a new vanadium pentoxide carbon fiber cloth (V 2 O 5 -CFC) is successful synthesized by means of electrospinning and...

Aqueous rechargeable zinc-ion batteries (AZIBs) have gained extensive attentions due to their high volumetric capacity, low cost, and intrinsic safety. Nonetheless, their zinc metal anodes have been suffered from many issues, such as uncontrollable dendrite growth and undesired side reactions,...

This paper seeks to investigate the time-varying dynamic conditional correlations to the five most important future metal markets, namely Gold, Silver, Copper, Zinc and Aluminium. We employ a multivariate Fractionally Integrated Generalized ARCH (FIGARCH) dynamic conditional correlation (cDCC)...

An experiment was conducted at Horticulture farm, Sher-e-Bangla Agricultural University, Dhaka-1207, Bangladesh from November, 2011 to June, 2012 to find the out better level of zinc on growth, flowering and production of corms and cormels of gladiolus. Experiment consisted four different levels...

Transition metal complexes of nickel(II) and zinc(II) with 5-bromo- N -(8-quinolyl)salicylaldimine (HqsalBr, HL 1 ) and 3,5-dibromo- N -(8-quinolyl)salicylaldimine (HqsalBr 2 , HL 2 ) have been synthesized and successfully characterized using several techniques: IR, 1 H-NMR, mass spectrometry...

This paper presents a study on cluster development of Zinc industry in Zanjan province. The industrial clusters are a model of industrial organization which has entered in industrial development literature through recent decades as one of the newest strategies for regional development. The...

Groundnut an oilseed crop is highly grown under arid and rainfed conditions with zinc deficiency which is an zinc responsive crop. The deficiency occurs as a result of no application of organic manures and dependence of high analysis fertilizer. Zinc as a cofactor of many enzymes, enhances...

Non-ferrous metals are widely used as basic materials in various industrial fields, and zinc is a metal that is produced and used next to iron, aluminum, and copper. In this study, DEA (data envelopment analysis) was applied to measure the efficiency of 43 zinc smelters in three countries in...

The desire for press hardened components in heavy-duty corrosion applications led to the development of Zn-based coatings with active corrosion protection. Unfortunately these coatings show cracks after press hardening with the risk of propagation into the steel. This project aimed at increasing...

The aim of this study was to evaluate the impact of microbial phytase addition to laying hen diet on the balance of phosphorus, calcium, manganese and zinc. Phytase supplementation caused a decrease in phosphorus excretion by 8% in the group with low-phytase diet and 21% in the group with...

Stormwater runoff, a substantial source of nonpoint pollution, can be treated using Best Management Practices (BMPs), such as the Media Filter Drain (MFD). An MFD is a trench filled with an engineered media mix, usually with a grass overlay, that receives runoff from the paved roadway next to...

"Hailian Chen's pioneering study presents the first comprehensive history of Chinese zinc--an essential base metal used to produce brass and coin and a global commodity--over the long eighteenth century. Zinc, she argues, played a far greater role in the Qing economy and in integrating China...

Micronutrient malnutrition, also known as hidden hunger, affects two billion people worldwide. In recent years, the global challenge of reducing hidden hunger and hence improving related health outcomes through agricultural interventions has received much attention. One potential solution is...

В статье рассмотрены перспективные направления расширения минерально-сырьевой базы российских производителей цинка на основе рециклинга техногенного сырья....

Objetivo: determinar, desde la perspectiva del sistema de salud colombiano, la relación de costo-efectividad de la suplementación con zinc para la prevención de la enfermedad diarreica aguda (EDA) en niños menores de cinco años.

Trends and prospects of international major commodity prices. In 2012, the international commodity markets have seen declining prices, especially during the first half of the year, with some improvement mainly in the last quarter. On the whole, most of major commodity prices declined, following...
