Authors: Sapkota Mahesh , Joshi Niraj Prakash , Kattel Rishi Ram , Bajracharya Mahima
Published: May 2017

This paper aimed to assess the technical efficiency of maize seed production and the major factors contributing on technical efficiency. Maize is the second most important staple crop in Nepal, but the average yield of maize is very low as compared to other countries having similar agro-climatic requirements. Inefficient use of resources had led to low yield in maize crop. The software Raosoft was used to determine the required sample size and total of 182 samples were selected using simple random technique in June, 2016. Stochastic production frontier model and Tobit model were used to derive the results. The average technical efficiency of maize seed production ranged from 0.25-0.92 with an average of 0.71which revealed the scope of increasing technical efficiency by 29 percent. The majority of the farmers (29.1%) were at higher technical efficiency level of 0.8-0.9 followed by 28.6 percent at 0.7-0.8 and 23.1 percent at 0.6-0.7. Age and schooling of household head, experience on maize seed production, area shared by maize crop and dummies variables such as livestock holding, source of seed and access to extension service had found significantly affecting on the technical efficiency level. For the least developed country like Nepal it would be better to use the available resources wisely and improvement of existing technologies would be more cost effective than that of discovering new technologies. The study recommended that the concerned organizations should focus on mixed agricultural farming system, access to better quality seed and provide technical knowledge which would help in improving technical efficiency.

Published: May 2017

Plant life-long organogenesis involves sequential, time and tissue specific expression of developmental genes. This requires activities of Polycomb Group (PcG) and trithorax Group complexes, respectively responsible for repressive Histone 3 trimethylation at lysine 27 (H3K27me3) and activation-related H3K4me3. However, the genome-wide dynamics in histone modifications that occur during developmental processes have remained elusive. Here, we report the distributions of H3K27me3 and H3K4me3 along with transcriptional changes, in a developmental series including Arabidopsis leaf and three stages of flower development. We found that chromatin mark levels are highly dynamic over the time series on nearly half of all Arabidopsis genes. Moreover, during early flower morphogenesis, changes in H3K4me3 prime over changes in H3K27me3 and quantitatively correlate with transcription changes, while H3K27me3 changes occur after prolonged expression changes. Notably, early activation of PcG target genes is dominated by increases in H3K4me3 while H3K27me3 remains present at the locus. Our results reveal H3K4me3 as greater predictor over H3K27me3 for transcription dynamics, unveil unexpected chromatin mechanisms at gene activation and underline the relevance of tissue-specific temporal epigenomics.

Thermoelectric materials may be used in devices as thermoelectric “air conditioner” in a smart house for improved energy efficiency. Energy harvesting uses ambient energy to generate electricity. It provides potentially low-cost, maintenance-free, long-life equipment by reducing the need for batteries or power chords. Energy harvesting (EH) is also known as power harvesting or energy scavenging. EH is considered to give benefits related to environmental friendliness, safety, security, convenience and affordability. EH can be used for brand enhancing. Technically, it can be used to make new things possible depending on visionary engineering. The variety of thermoelectric (TE) materials that can be used in energy harvesting is quite large, and the optimal material for a given application depends mainly on the temperature range in which the material is to be used.  In this work we study the development and characterization of thermoelectric materials which were prepared by two different method, which were: a) ball-milling followed by sintering and b) ball-milling, microwave synthesis, high energy planetary ball milling, and sintering. Finally, we study the thermoelectric properties, calculate the band gaps and the ZT for the thermoelectric materials.

Core Ideas

High sorghum density and narrow row spacing reduce biomass of troublesome weeds.

High spatial crop uniformity extends large crabgrass and sicklepod control over time.

Optimized crop density and row width may limit the need for postemergence herbicide in sorghum.

Sicklepod [Senna obtusifolia (L.) H.S. Irwin & Barneby] and large crabgrass (Digitaria sanguinalis L.) are ranked among the top 10 most common or troublesome weeds in grain sorghum [Sorghum bicolor (L.) Moench] in the southeastern United States. Field studies conducted in North Carolina from 2012 to 2014 investigated the effects of three row widths, four sorghum populations, and three herbicide programs on weed control, density, biomass, and grain yield. Results indicated that 19‐ and 38‐cm rows provided greater sicklepod control 7 and 10 wk after planting (WAP) compared to 76 cm but had no effect on crabgrass control. Under weed‐controlled conditions, sorghum population ≥297,000 plants ha−1 allowed to maintain higher late‐season sicklepod and crabgrass control as compared to lower crop densities. In the weedy control, row spacing had no effect on weed density and biomass, whereas crop population ≥297,000 plants ha−1 reduced sicklepod density and biomass by 38 and 65%, respectively, compared to 99,000 plants ha−1. Effect on crabgrass was less pronounced with density and biomass reduction by 18 and 45%, respectively, for 396,000 plants ha−1 compared to 99,000 plants ha−1. In the absence of water stress, the highest grain yields were obtained with high spatial uniformity, corresponding to 19‐cm rows and sorghum population ≥297,000 sorghum plants ha−1. Our results indicate that increased sorghum density associated with narrow rows may reduce the need for a postemergence (POST) herbicide but underscore the importance of a timely activated preemergence (PRE) treatment to efficiently control sicklepod and crabgrass.

Published: May 2017

Global warming would deteriorate rice (Oryza sativa L.) quality, especially chalk characteristic. To better cope with the challenges from global warming, the effects of nitrogen (N) fertilizer at heading stage on rice quality under elevated temperature during grain‐filling stage were investigated. Four different growth regimes, including no warming without N fertilizer at heading stage (CK), elevated temperature without N fertilizer at heading stage (ET), elevated temperature with N fertilizer at heading stage (ET+N), no warming with N fertilizer at heading stage (CK+N), were conducted. Elevated temperature during grain filling was achieved by a free‐air temperature enhancement facility with the increase of 4°C in ET and 3.7°C in ET+N. Results showed that elevated temperature decreased rice appearance quality and cooking quality and increased rice nutritional quality and eating quality. Grain‐filling rate and amyloplast development for both superior and inferior spikelets were obviously accelerated during early grain‐filling stage by elevated temperature. The application of N fertilizer at heading stage could inhibit the deterioration of rice quality, particularly for chalk performance, and may be associated with the alleviation of grain‐filling rate and amyloplast development. The above evidence indicated that the application of N fertilizer at heading stage is efficient to mitigate rice quality deterioration under higher temperatures in the Yangtze River Valley.

Core Ideas

We devised a setup to measure hydraulic properties using the multistep flux method.

Results showed good agreement with the data obtained with the hanging water column.

However, they deviated slightly from independent data obtained with the HYPROP.

Knowledge of the unsaturated soil hydraulic properties is essential for modeling water flow and solute transport processes in variably saturated subsurface systems. Various experimental setups have been developed over the years to measure the hydraulic properties. We devised a relatively simple setup for simultaneous measurement of the water retention and unsaturated hydraulic conductivity curves using multistep flux (MSF) and hanging water column (HWC) experiments. Our focus was especially on medium‐ and coarse‐textured sands having relatively narrow particle‐size distributions as reflected by the van Genuchten–Mualem (VGM) hydraulic parameter n. Values of the VGM parameter n for some of the sands we used were as high as 15. We also measured the hydraulic properties using the HYPROP evaporation method. The MSF and HWC results showed excellent agreement, but deviated slightly from independent data obtained with the HYPROP measurement system.
Derivation and Validation of a New Soil Pore‐Structure‐Dependent Flux–Saturation Relationship
Authors: Ma DongHao , Zhang JiaBao , Lu YunXuan
Published: May 2017

Core Ideas

A soil pore‐structure‐dependent soil water flux–saturation relationship F(Θ) was derived.

This F(Θ) depends on the shape coefficient of soil water retention curve and initial saturation.

This F(Θ) is simple and accurate for constant‐saturation infiltration and absorption.

Recently, a method based on the soil water flux (F)–saturation (Θ) relationship, F(Θ), assumed to be independent of time and soil properties, has become an important technique to simplify solving Richards' equation so as to develop a simple, rapid, and low‐cost approach to estimate soil hydraulic properties. However, the actual F(Θ) is soil pore‐structure dependent. So far, there exists no theory that can provide a specific functional form of soil pore‐structure‐dependent F(Θ). In this research, we derived a general soil moisture profile function and then a general expression of F(Θ): F = Θ[1 + a2(1 −)]. The only parameter in F(Θ), a2, is a function of the initial soil water saturation and the soil pore structure index that reflects the shape of the soil water retention curve. Infiltration experiments with three test soils and four actual soils were conducted to test the proposed relationships. The results verified the independence of F(Θ) on time at small time scales. The results also indicated that the derived formula predicted F(Θ) in good agreement with what was measured for all test soils under different initial soil moisture conditions. In addition, the upper and lower limit curves of F(Θ) calculated by the proposed formula were consistent with the theoretical curves. Compared with other empirical relationships, the new formula was the best for describing the theoretical upper limit curve of F(Θ). Furthermore, the new theoretical relationship was also found to be appropriate for horizontal absorption. Generally, the developed relationship is more accurate and helpful to solve Richards' equation.

From the corporate social responsibility reporting to the integrated reporting: the case of Sabaf S.p.a
Authors: Camodeca Renato , Almici Alex
Published: May 2017

In December 2013, the International Integrated Reporting Council (IIRC) published the International Integrated Reporting Framework. The aim of the Framework is to provide the guiding principles and the content elements of an integrated report. The integrated report constitutes an evolutionary step in the corporate’s financial and non-financial communication, moving from the social responsibility reporting to the integrated reporting. This practice is at the beginning in Europe and especially in Italy, where only a few listed companies have decided to face the multitude of challenges the integrated report implies. Considering the relevance of such a new form of communication, the paper examines the main steps carried out by an Italian listed company moving towards the integrated report. The research has been conducted by adopting a qualitative case study approach, by focusing on Sabaf S.p.a, an Italian listed medium sized company belonging to the Star Segment. This company has been selected, because it was one of the first adopters of the integrated report among the Italian listed companies. The study is built on data gathered through sites visits, structured interviews and company materials. The paper examines Sabaf’s transition from the corporate social responsibility report to the integrated report, aiming at answering the following research question: Why has Sabaf moved to integrated reporting? Which are Sabaf’s main steps towars the integrated report? How is the Sabaf’s integrated reporting process going? The findings should be of interest to a number of parties including standard setters, firms, financial advisors, auditors and users of non-financial statements.
Entrepreneurship education and its impact on the entrepreneurship career intentions of vocational education students
Authors: Munyaradzi Ndofirepi Takawira , Rambe Patient
Published: May 2017

The rich body of literature examining the entrepreneurship education-entrepreneurship intention relations tends to neglect the influence of contingent and other mediating factors on the relationship. This elusion creates an erroneous assumption that entrepreneurship intentions are insulated from external influences and the entrepreneurship education-intentions relationship is an automatic, directly linear interaction. Contesting this premise, this research explores the influence of exposure to entrepreneurship education (EE), mediated by precursors (such as attitude, subjective norms and perceived behavioral control) to entrepreneurial intentions on the actual entrepreneurship intentions (EI) of vocational education students at a particular institution in Zimbabwe. Drawing on a cross-sectional research design and 154 randomly selected students, the study examines the extent to which they intended to engage in entrepreneurship careers in the near future. A non-parametric technique, the Spearman correlation test, and regression analysis were employed to test the relationships between EE on the direct determinants of EI, between the immediate determinants of EI and actual EI and to test a number of predictive effects. The results demonstrate that EE had a positive correlation with the direct determinants of EI. In addition, EE predicted all the immediate determinants of EI, except for subjective norms. Lastly, there was no evidence to support a direct predictive effect of EE on EI, controlling for other psychological factors. To a large extent, the results validated the Theory of Planned Behavior as a guiding tool for estimating any premeditated entrepreneurial behavior. Thus, the Theory remains an invaluable theoretical lens for academics, educators and policymakers’ evaluation of effective ways of enhancing the grooming of potential entrepreneurs.

To overcome the excessive heat in tropical climate countries during the day, the types of skin or façade play a vital role in regulating the temperature and the amount of heat transmission in a building. This research was carried out to evaluate the percentage of temperature reduction of two building samples, one with “vertical greening” and one without. The result proved that the temperature reduction of the building with the green façade system is higher than the building without the green façade system. Therefore, it justifies that Vertical Greening Wall does act as an acceptable passive approach for sustainable design.

Why friends pay more: An alternative explanation based on self-expansion motives
Authors: Kou Yan , Powpaka Samart
Published: May 2017

Using the self-expansion model as a theoretical basis, we examined how friendship can benefit a business while avoiding the conflicts that are predicted in the relationship-norm framework. We proposed that engaging in self-expansion would automatically motivate a customer to take psychological
ownership of the product, promote favorable attitudes toward the seller, and increase product knowledge, thereby affecting the customer's perceived product quality and subsequent product valuation. Empirical results from 266 respondents who were customers at 193 restaurants supported most
of our hypotheses. Mediation analysis indicated that the relationship between friendship and product valuation was jointly mediated by psychological ownership and attitudes toward the seller ; however, the mediating role of product knowledge was not supported, which suggests that in the context
of friendship, judgments about products are based more on the friend than on the product itself. Theoretical and practical implications are discussed.

The mathematical models for the prediction of the pastures growth present potential of use for answer scientific, agronomic and planning questions, helping in the understanding about the physiological, genetic and environment interactions, as also in the decisions of management practices and in the scenery prevision. There are several methods to calculation the potential performance, however it´s necessary correlate those more adjusted to real field conditions, in function of the diversity of biotics and abiotics factors that affect the growth and development of the plants and, consequently, in the forage yield potential performance. Among the methods evaluated for the estimate Axonopus aureus, forage potential performance, during rainy season, the method proposed by Doorenbos and Kassam (1994) provided better adjusted to the field conditions, whereas the Sinclair (1993) method provided estimates of the grass growth potential, which can be obtained under extremely favorable environmental conditions and the utilization of better pasture management practices. The method of Loomis and Williams (1963) estimated a very highest productivity, and showed inadequate for simulate grass growth potential under real conditions. The acurate of the models in predict the potential performance was directly proportional to incorporates sensibility parameters that consider the prominent of abiotics and physiological phenomena involved in the biomass accumulation.

Although Brazil has one of the largest pig herds in the world, still has a low rate of productivity swine, where small and medium farms account for a large portion of the creations. The pigs are affected by many species of parasites that cause irritation to the gastrointestinal mucosa, lack of appetite interfering with the daily weight gain. This study aimed to survey helminthological pigs coming from creations in the Mossoró city, Rio Grande do Norte. Has been analyzed 200 swine feces samples collected between period 2005 to 2009 and examined by specialized bibliographies. Was found the following helminthes: Ascaris suum, Balantidium coli and Isospora suis. The major prevalent parasitism was by I. suis (50.0%), followed by B. coli (33.3%). The endoparasites association with more than one parasite in a single swine (16.7%) was watched I. suis and A. suum.

The objective was to characterize and evaluate the physical and chemical properties of soils under pastures in the south of Tocantins. The study was conducted in areas with degraded pastures located in the municipality of Gurupi Fazenda Chaparral. Data analysis of the experiment was performed by using classical statistical analysis of variance and subsequent test of means depending on the level of pasture degradation (1, 2 and 3) in the same area of soil class and in relation to the depths of (0 -10 cm, 10-20 cm, 20-30 cm) in a 3x3 factorial arrangement from the physical variables: total porosity, particle density, bulk density. Data were subjected to analysis of variance and comparison of means by Tukey test at 5% probability. It was observed that soil density and penetration resistance increases and porosity decreases with increasing stages of degradation of pasture.

Studies on Animal Welfare have importance to veterinary and scientific community in view of the small amount of work in this area. Taking into account that Brazil is one of the largest exporters of beef, pork and chicken, and that importing countries are demanding these products, increasingly, the use of practices that respect the Animal Welfare, it is evident the need to know the reality of the slaughter establishments. Aiming to achieve a quality standard under the commercial point of view and humane slaughter. In this sense it is proposed to a survey in order to investigate the levels of Animal Welfare, through the evaluation of management practices and slaughter in a slaughter plant in Uberlandia - MG. Data were collected through a standardized questionnaire in seven site visits, evaluating indicators in the stages of pre-slaughter and slaughter. After collection, the data were processed and arranged in tables. For analysis, data were transformed into indicators and compared with the literature. This comparison showed the presence of indicators of Animal Welfare, among the subjects studied in the slaughter plant, in violation of the Animal Welfare levels accepted. We conclude that the presence in the slaughterhouse assessed for indicators of Animal Welfare outside the acceptable standards is associated with factors such as inadequate management due to lack of training and insufficient level of knowledge about animal behavior, by employees.

Was attended at the Veterinary Hospital of Unicastelo Descalvado Campus, a female Boxer, seven years old and weighing 24 pounds. The animal had an ulcerated tumor located in the inner left thigh approximately 8cm in diameter. The animal was submitted to the examination of fine needle aspiration cytology (FNAC), where was found a cellularity consistent with basal cell carcinoma. After routine tests such as blood, urine and feces, the animal was pre-anesthetized with levomepromazine (0.3 mg/kg), induced with propofol (3 mg/kg), anesthesia was maintained with isoflurane. Was also made by the epidural the combination of morphine at a dose of 0.1 mg/kg, supplemented with local anesthetic bupivacaine 0.5%, the amount of one ml for four pounds. Thirty minutes before the first surgical incision, was given the antibiotic enrofloxacin (5 mg/kg IV). Was performed resection of the tumor while maintaining a safety margin of about 2 cm along its entire length. To cover the lesion, was created a pedicle axial pattern of the ventral abdomen, preserving the epigastric artery and vein flow. The flap was transposed onto the wound skin of medial left thigh, and the ends of the graft were sutured to the recipient bed, with nylon, in wolff  pattern, with nylon. Some simple interrupted suture points were applied between the inner face of the graft and wound bed, using vicryl an attempt to decrease the dead space between the graft and the lesion. The skin wound of the ventral portion at abdomen where was removed the graft was approximated and sutured in a conventional pattern. Postoperative care consisted of administration of opioids tramadol dose 2.0 mg/kg subcutaneously each 12 hours for five days, ketoprofen (2.2 mg/kg) every 24 hours over three days and enrofloxacin (5,0 mg/kg) every 24 hours for 10 days orally. Elapsed 20 days of surgery the wound had healed completely with the adhesion of the graft.

The meat inspection is carried out in countries around the world. It is extremely important to control diseases that cause loss of production and productivity to the national livestock and pose risks to human health, such as mastitis or mastitis, which can cause sepsis and result in a condemnation of the carcass slaughtered. The objective was to make a survey of mastitis in cattle carcasses slaughtered in the states of Goias, Mato Grosso do Sul, Minas Gerais and São Paulo subject to the control of the Federal Inspection Service in the period 2006 to 2009, and detect the number of cases in each municipality. Through the post-mortem examination the mammary glands were removed intact and the diagnosis was made ​​through its macroscopic view. We conclude that a total of 268,703 animals slaughtered only 57 had findings of mastitis, which represents 0, 021% and that mastitis is a disease that affects more cattle for milk production than meat production.

In today's world, where maize is being used for ethanol production, the use of alternative foods feed assumes a relevant role. The Brazilian poultry and pork have gone through periods of constant instability, especially for the low price of the product associated with the high costs of production and supply has been the focus of greater participation in the total cost of production, representing a percentage from 70.0 to 75, 0% of the total cost of the activity. Because of this and virtues of the ingredients used in feed for swine and poultry in Brazil are corn and soybean meal, a change in the price of these inputs can have direct impacts on the producer's profit margin. In recent years, research efforts involving the use of alternative foods, especially by-products or waste resulting from industrial processing of agricultural products and practices of modern mechanization, have aroused the interest of the scientific community. The surveys have been instrumental for the discovery of new ways of using the products and by-product, and limitations for different categories of animals within each species. Currently, besides the agricultural branch of research, studies on the use of renewable energy have been intensified. Among the renewable sources has received great attention biodiesel. However, the increase in biodiesel production could be economically viable only if it finds new uses for the products generated, such as crude glycerin. It has been found that for every 90m ³ of biodiesel produced by transesterification reaction, are generated 10m ³ of crude glycerin. Glycerin when purified can be used in the production of tobacco, in the food industry, beverages and cosmetics products. However, complex processes are needed and high cost of raw material that reaches the purity requirements necessary for these purposes. With the recent surge in biodiesel production and the availability of large quantities of crude glycerin has been interest in its use in animal feed. There are studies whose results indicate the possibility of use of this byproduct in diets as an energy source for pigs and poultry because it is rich in energy.
