Women in Islamic Education Management: Learning from Pesantren Practices
Authors: Hidayah Siti Nur , Arifi Ahmad 
Published: July 2017

This paper focuses on two issues. Firstly, the role performed by women (nyais) in managing pesantren by considering the issue of work division, authority and responsibility principles in management practices. Secondly, it observes on how knowledge is managed and preserved in pesantren. This paper is based on reviews of the previous research about women and pesantren. Thi study shows that there are three types of nyai’s role in managing pesantren education. First, a nyai who hold clear responsibility, work division and at the same time owned authority in managing a male and female students. Second, a nyai who has a clear division of work, and responsibility but does not have authority in managing a male and female students. And third, a nyai who leads a sepcific female pesantren and hold authority, responsibility and task in developing her pesantren. It is through various method of learning, espceially memorization of knowledge and the Qur’an, that tradition and knowledge of Islamic tradional subjects in pesantren are preserved and practiced.
EFFECTS OF WIND FARM OPERATING REGIMES IN THE POWER SYSTEM OF MACEDONIA

Published: July 2017

A b s t r a c t: The trend for achieving sustainable energy development, keeping the environment clean and utilization of renewable energy sources are imperative to the energy development in several countries. Through legislation and economical benefits, countries tend to encourage potential investors for building the technologies for energy production from renewable. In order to achieve the EU energy target to have 20% renewable in 2020, the technologies for producing electricity from renewable energy sources (RES) are used to cover the needs with more intensities. The most dominant renewable is the wind power plants(WPP) or wind parks, which are used to supply electricity to more power systems (EPS) and whose installed capacity in some European countries reaches thousands MW. This paper treats the issue of operational work of wind power in the power system of Macedonia. It is made of simulation work with wind power plants with total installed capacity of 150 MW with an annual production of 300 GWh. The considered power system of Macedonia is projected for the period of 2015 with an annual consumption of 10,000 GWh. The power plants considering operating in the simulated period are the existing thermal power units and hydro power plants together with the planned gas power plants and hydro power plants. The aim of this paper is to analyze the effects of the power system operation in case to have installed wind power plants, or what operation mode of thermal power plants (TPP) and hydro power plants (HPP) is most convenient when the system has a source of technology from the renewable with stochastically nature. This is especially important, because conventional power plants (TPP and HPP) operate and regulate the needs of consumption in the power system, but the wind power plants operate when the wind occurs within certain limits of technical operating mode for wind turbines. Although wind is free renewable energy source, frequency of occurrence of wind with unpredictable nature and stochastically, has additional adverse impact in terms of power system operating mode. Certainly the impact of wind power on the overall the power system operation depends on power plants and configuration of the power system. In other words, the base load is covered from TPP fossil fuel or nuclear plants, and the dynamic nature of wind power can be incorporated in the power system depends on how much power plants for peak load are available in the system (storage reversible hydro or gas turbines), or how variable power can be accepted in the power system.

This document has as main objective to discuss the dual role that China is playing in Latin America, on one hand, a strategic trade partner in Asia, source of foreign direct investment (FDI) and key ally in the international arena, on the other hand, China is a formidable competitor particularly in the manufacturing sector. To reach the main objective, we make a brief description of the international trade relation between China and Latin America for the last 15 years, also, a review of the investment flows in different economic sectors, and lastly, a description of the political and diplomatic relation between Latin America and China. From this, it can be inferred that the bilateral relation is prominently framed by the trade of commodities from Latin America to China and the Chinese investment in the sourcing of natural resources.

Este trabajo presenta un análisis de la política monetaria no convencional puesta en marcha por la FED, teniendo en cuenta los objetivos de cada una, la teoría económica que la sustenta y el impacto en los principales indicadores de la economía de los Estados Unidos y de la economía colombiana y un breve comentario del impacto en los índices de las bolsas de valores de economías emergentes. En aquel país, se observa el efecto de las tres etapas del programa en indicadores de interés, como los agregados monetarios, la tasa de desempleo y los activos financieros de renta fija. En la economía colombiana, se observa el impacto de la flexibilización cuantitativa en el índice COLCAP, la rasa representativa del mercado (TRM), el precio del crudo de Texas (WTI) y la inversión extranjera directa (IED) durante el periodo 2010 y 2015. Al finalizar el estudio, se encuentran las evidencias que permiten resaltar el efecto de la política sobre estos cuatro indicadores económicos. Para observar los efectos en el índice COLCAP, la TRM y el WTI, se construye un modelo de mínimos cuadrados ordinarios (MCO) que nos permite ver la volatilidad de las acciones y las variaciones de el WTI, basados en el modelo de valoración de activos financieros (CAPM ‘capital asset pricing model’), finalizando con la decisión de la FED de endurecer su política monetaria en diciembre de 2015.

Core IdeasHigh stress enhanced protein concentration, but reduced total starch concentration.High stress had more advantage effects on protein fractions at anthesis than 10 d after anthesis.High stress had significant negative effects on starch during grain filling.The combination stress did not have significant effects on protein fractions.The combination stress had significant effects on starch concentration.The protein and starch properties of wheat (Triticum aestivumL.) are important factors for grain quality and these properties are documented to be influenced by temperatures. The present study was undertaken to investigate the effects of high temperature regimes, starting dates, durations and their combinations on grain protein and starch concentrations in two wheat cultivars Yangmai16 and Xumai30 with different heat tolerances. Four temperature regimes of 27/17°C, 31/21°C, 35/25°C, and 39/29°C were implemented for 3 and 6 d after anthesis and 10 d after anthesis. The concentrations of protein and starch components in grains were measured during the periods of postanthesis. High temperature enhanced both protein and amylose concentrations, but reduced amylopectin and total starch concentrations in grains. Higher concentration of protein fractions were observed when high temperatures were applied at anthesis than during the grain‐filling stage (10 d after anthesis). However, high temperatures during grain filling had profoundly more negative effects on starch concentration than at anthesis. The combination of high temperature regimes and durations did not have significant effects on the protein fractions, compared with either of the temperature regimes or durations applied individually, which was different from the starch concentration in response to the combination. Nevertheless, the combination of temperature regimes and durations could not cause more changes to grain starch concentrations than a single stress event.

Authors: Johnson Gregg A. , Wells M. Scott , Anderson Kevin , Gesch Russ W. , Forcella Frank , Wyse Donald L. 
Published: July 2017

Core Ideas
Winter annual oilseed crops are being used in annual cropping systems to add value.
We explored trade‐offs in oilseed yield and provision of ecosystem services.
Oilseed cover crop yield was greatest when harvested late rather than early.
Pennycress and camelina reduced N in the soil profile compared to soybean alone.
To gain additional value from land during winter fallow periods in corn (Zea mays L.)–soybean [(Glycine max (L.) Merr.] rotations, growers in the Upper Midwest are considering winter annual oilseed crops such as field pennycress (Thlaspi arvense L.) and winter camelina [Camelina sativa (L.) Crantz]. The objective of this study was to (i) explore trade‐offs between soybean and winter oilseed crop yield as influenced by timing of winter oilseed crop harvest and of soybean planting, and (ii) evaluate how inorganic soil N was affected by the presence or absence of pennycress or camelina. Field experiments were conducted at three sites in Minnesota to evaluate yield of field pennycress and camelina winter oilseed crops planted in a double‐crop system or planted early or late in a relay‐cropping system. Soybean grain yield was reduced in one of the three sites in 2014 and at all sites in 2015. However, the addition of a winter oilseed crop in a relay‐ or double‐crop system increased the total oilseed production. The optimal cropping strategy for achieving maximum total oilseed crop yield was dependent on environment. Winter oilseed crop yield tended to be greatest when harvested late rather than early in either a relay‐ or double‐crop system. Pennycress and camelina significantly reduced inorganic soil N along the entire soil profile compared to soybean alone, especially in the spring (53–72%) and autumn (18–19%) when the potential for N loss is greatest. Pennycress and camelina, when integrated with soybean in a late‐planted relay‐ or double‐crop system, increased total crop yield while providing critical ecosystem services.
Evaluation of Nitrogen Fertilizer Additives for Enhanced Efficiency in Corn on Iowa Soils
Authors: Barker Daniel , Sawyer John 
Published: July 2017

Core Ideas
Landscape position was selected and N fertilizer treatments were designed to promote significant denitrification and enhanced potential volatilization.
No agronomic benefit was found using urea with nitrification and urease inhibitors or urea with a polymer coating.
Lack of response to inhibitor products and coated urea were likely due to rainfall timing and amount shortly after application, reduced volatilization due to high soil retention of NH4, and slowed nitrification rates from cool soil temperatures after application.
Recent years of high rainfall and prolonged wet soil conditions in Iowa have renewed interest to protect losses of fertilizer nitrogen (N) in corn (Zea mays L.). This study evaluated effect of N additives and a slow‐release urea product on the soil NO3–N fraction of total inorganic N, mid–vegetative growth N stress, grain yield, and corn nitrogen use efficiency (NUE). Field trials were conducted at two Iowa State University Research Farms in 2013 and 2014. Sites were selected for probable response to applied N with different nitrification product treatments and coated urea (fine‐textured soils that were poorly drained with high organic matter) and urease inhibitor products (incorporated vs. unincorporated). Urea and treated urea were applied at 120 lb N/acre and incorporated and left on the surface. Overall, there was no agronomic benefit from using urea with nitrification inhibitors (Instinct and SuperU), urea with urease inhibitors (Agrotain, SuperU, and Factor), or urea with a polymer coating (Environmentally Smart Nitrogen). Lack of response to nitrification and urease products was potentially due to climatic conditions during the study. Significant rainfall shortly after N application moved urea into the soil profile (minimizing NH3 volatilization) and slowed nitrification rates from cool temperatures early in the season.

Published: July 2017

Pine (Pinus spp.) bedding has been shown to lower the concentration of odorous volatile organic compounds (VOCs) and pathogenic bacteria compared with corn (Zea mays L.) stover bedding, but availability and cost limit the use of pine bedding in cattle confinement facilities. The objectives of this study were to determine if the addition of pine wood chips to laboratory‐scaled bedded packs containing corn stover (i) reduced odorous VOC emissions; (ii) reduced total E. coli; and (iii) changed the nutrient composition of the resulting manure‐bedded packs. Bedding treatments included 0, 10, 20, 30, 40, 60, 80, and 100% pine chips, with the balance being corn stover. Four bedded packs for each mixture were maintained for 42 d (n = 4 observations per bedding material). The production of total sulfur compounds increased significantly when 100% pine chips were used (44.72 ng L‐1) compared with bedding mixture containing corn stover (18.0–24.56 ng L−1). The carbon‐to‐nitrogen ratio exceeded the ideal ratio of 24:1 for the optimum activity of soil microorganisms when ≥60% pine chips (25.3–27.5 ng L−1) were included in the mixture. The use of 100% pine chips as bedding increased sulfide concentration in the facility 1.8 to 2.4 times over the use of corn stover bedding. Escherichia coli was not influenced by the addition of pine chips to the corn stover bedding material but did decrease as the bedded pack aged. Bedding material mixtures containing 30 to 60% pine and 40 to 70% corn stover may be the ideal combination to mitigate odors from livestock facilities using deep bedded systems.Core Ideas
Mixtures of bedding material containing at least 40% pine chips may reduce odorous BCFAs.
Even 10% pine chips in the bedding mixture will lower concentration of skatole by 64%.
Use of 100% pine chips for bedding increases sulfide 1.8–2.4 times compared with corn stover bedding.
E. coli is not influenced by pine chip addition to the bedding mixture.
Bedding mixtures with 30–60% pine may mitigate odor from livestock facilities.

Published: July 2017

The recycling of urban waste products as fertilizers in agriculture may introduce contaminants such as heavy metals into soil that may leach and contaminate groundwater. In the present study, we investigated the leaching of heavy metals from intact soil cores collected in the long‐term agricultural field trial CRUCIAL. At the time of sampling, the equivalent of >100 yr of urban waste fertilizers following Danish legislation had been applied. The leaching of Cu was significantly increased in the treatments receiving organic waste products compared with the unfertilized control but remained below the permissible level following Danish drinking water guidelines. The leaching of Cu was controlled primarily by the topsoil Cu content and by the leaching of dissolved organic carbon (DOC) but at the same time significantly correlated with leaching of colloids in soils that had not received fertilizer or had received an organic fertilizer with a low concentration of Cu. The leaching of Zn, Cd, and Co was not significantly increased in urban waste‐fertilized treatments. The leaching of Mo was elevated in accelerated waste treatments (both agricultural and urban), and the leaching of Mo was linked to the leaching of DOC. Since leaching of Cr and Pb was strongly linked to the level of colloid leaching, leaching of these metals was reduced in the urban waste treatments. Overall, the results presented should not raise concern regarding the agricultural use of urban waste products in agriculture as long as the relevant guidelines are followed.Core Ideas
Urban waste fertilizers do not lead to increased leaching of Cd, Co, Cr, and Pb.
Leaching of Cu may be driven by colloids when there is a limited DOC leaching.
Mo leaching may be driven by the leaching of DOC.
