Field evaluation of a grain drill equipped with jointers for direct planting in previous wheat crop residues

ARTICLE INFO ABSTRACT-In conventional agriculture, a large amount of energy is consumed in fuel consumption and depreciation of farm tractors and any other farm equipment mostly in tillage and planting operations. The main purpose of this research was to evaluate a tillplanting unit equipped with three jointers. This unit was expected to act as conventional furrow openers such as shovel openers tilling the soil and plant simultaneously, which could reduce farm traffic and farming costs. The unit performance was compared to that of a grain drill. The control experiment was conducted on a moldboard plowed soil, disked by a tandem disk harrow and planted by a pneumatic grain drill. The experimental site was also covered with previous wheat crop residue and the soil was clay with loam at 15.2% d.b. moisture content. The working depth was 6 and 20 cm for direct planting and conventional system, respectively. The experiments were performed at three tractor forward speeds (4, 6 and 8 km h) in triplicate in the Experiment Site of Shiraz University, Shiraz, Iran. Results indicated that the direct planting system reduced the operation time, fuel consumption, draft and specific drawbar energy 65, 60, 75 and 80%, respectively as compared to the conventional practice. However, values of the mean weight diameter and seedling growth rate did not show any significant difference in the two cases at 5% level. Furthermore, moisture retention in direct planting system increased 1.87% per 10 days as compared with the conventional farming system.

Photoconductive terahertz detectors based on single GaAs/AlGaAs nanowire were designed, fabricated and incorporated into the pulsed time-domain technique, showing a promise for nanowires in terahertz applications such as near-field terahertz sensors or on-chip terahertz micro-spectrometers.
MIDAS Volatility Forecast Performance Under Market Stress: Evidence from Emerging and Developed Stock Markets

We explore weekly stock market volatility forecasting performance of a univariate MIDAS volatility model based on squared daily returns vis-a-vis the benchmark model of GARCH(1,1) for four developed and ten emerging stock markets. We compare the out-of-sample forecasting performance of the MIDAS model during the financially turbulent year 2008. We show evidence that MIDAS model produce better weekly volatility forecast than the GARCH model based on the test suggested by West (2006). MIDAS model could not generate a superior forecasting precision during more tranquil period.
Evaluation Of International Tourist Satisfaction In Weh Island Indonesia Using HOLSAT Model

The purpose of this research is to examine international tourist satisfaction in marine tourism, especially diving and snorkeling, in Weh Island Indonesia using Holsat Model. The data for this study come from survey in the field, by using questioners and interview, not only to tourists but also to other stakeholder such hotel owner, government officials, international NGO officers and other related parties. 200 Respondents were drawn from four (4) locations most tourists concentrated in Iboih, Sumur Tiga, Kota and Gapang by using stratified random sampling. The data was tabulated and processed by using Holsat Model that was developed by Tribe and Snaith (1998) as a research instrument for measuring holiday satisfaction. The international travelers were not really satisfied when visited Weh Island. This was because most of the attributes used to measure their satisfaction were still below their expectation. Thus, this finding is important for service providers like restaurants, travel agents, hotels, and tourist information centers in Weh Island to improve all the poor indicators rated by tourists. Furthermore, the findings demonstrate the usefulness of the HOLSAT model in three aspects: First; this study identifies tourists’ sense of satisfaction or dissatisfaction in terms of the various attributes of Weh Island as a holiday destination. Second; this study provides insights on how Weh Island is perceived as a holiday destination by international tourists. Third; this study provide a better approach to understanding of tourist behavior while they are visiting Weh Island, Based on the results of the comparison between expectations and experiences.
Market Structure and Optimal Entry Cost When Quality of Product is Uncertain

We investigated the government’s optimal intensity of product screening process prior to entry when the product’s quality is uncertain, such as medical devices, and showed that the intensity that maximizes social welfare is greater than the intensity that maximizes the number of entrants. In recent empirical research about medical devices, implications of uncertainty of product’s quality and screening process on consumer has been studied and it has been found that too weak screening intensity may not maximize the social welfare in some cases. We gave such empirical ndings a theoretical form by using a general reduced form model, and we also provided a structural example that is an extension of static two stage entry model. The policy implication from our argument is that the government may have to increase the intensity to improve the social welfare even though the number of entrants decreases, in other words, reducing entry costs may not be always good for society.
Management Systems and Good Practices Related to the Sustainable Supply Chain Management

The objective of this paper is to identify the good practices and management systems related to Sustainable Supply Chain Management SSCM. This study is qualitative with exploratory objective. By examining SSCM publications across journals and across time (from 1997 to 2011) in the three aspects of sustainability, there is a growing number from 2004/2005 onwards. The social aspect is rarely addressed in the literature, in contrast with environmental followed by the economic. The management systems reflect this finding as well as with the eight practices identified. There is no management system that addresses social responsibility. Only two practices address the triple bottom line aspects, while four address environmental and economic aspects, one deals with social and economic and one deals with environmental aspect. The two frameworks proposed by the authors are the contribution in this paper. The first relates the good practices adopted in SSCM to the three aspects of sustainability and their interactions. The second organizes the management systems in layers according to how they address the sustainability aspects. SSCM, as well as Sustainable Operations Management, present themselves as the most comprehensive management model. In SSCM new practices are used together with those found in the supply chain management.

It will also describe two EAC modules that have emerged in its initial stages of implementation. Finally, it will outline the activities, spell out the objectives, and summarize the assessment results of a series of interactive workshops held in the spring and fall of 2007.
Release of curcumin incorporated in albumin loaded silica

In this work, we have prepared a new drug delivery system consisting of silica (SiO2) as the main carrier, while albumin acted as the co–carrier in order to control the release of drug. The system was prepared by simple wet chemical method. The efficiency of the designed system was tested in the delivery of a hydrophobic drug, curcumin through an in–vitro procedure. The results show that the release percentage of curcumin was increased with the presence of the co–carrier. The intermolecular interaction of curcumin with albumin and the competition between them to locate on the surface of silica affect the release system. Besides, the curcumin release amount was corresponded to the composition of the silica carrier in the systems. Consequently, the potential for silica/albumin use as a drug carrier was ascertained.
Optical line shapes of dynamically disordered ring aggregates

We study the absorption line shape caused by Frenkel excitons in one-dimensional ring-shaped molecular aggregates, such as circular light-harvesting systems, subjected to dynamic disorder with a finite correlation time. We focus on dichotomic noise and show that for arbitrary orientations of the molecular transition dipoles relative to the ring, the absorption spectrum may be calculated exactly by solving two very similar sets of 2N coupled linear equations of motion, where N is the number of molecules in the ring. These sets are a factor of N smaller than in methods developed previously, which allows us to evaluate the exact line shapes for N up to 12 and study size dependence of the spectra. Previous exact calculations were limited to hexamers (N=6). Moreover, in contrast to earlier work, we take into account long-range dipolar transfer interactions between all molecules in the ring. We find that the dipole orientation and the long-range interactions strongly affect the dependence of the spectrum on the.
Numerical studies of thermal convection with temperature- and pressure-dependent viscosity at extreme viscosity contrasts

Motivated by convection of planetary mantles, we consider a mathematical model for Rayleigh-Benard convection in a basally heated layer of a fluid whose viscosity depends strongly on temperature and pressure, defined in an Arrhenius form. The model is solved numerically for extremely large viscosity variations across a unit aspect ratio cell, and steady solutions for temperature, isotherms, and streamlines are obtained. To improve the efficiency of numerical computation, we introduce a modified viscosity law with a low temperature cutoff. We demonstrate that this simplification results in markedly improved numerical convergence without compromising accuracy. Continued numerical experiments suggest that narrow cells are preferred at extreme viscosity contrasts, and this conclusion is supported by a linear stability analysis.
Analysis of Insertion Copy Number and Integration Site of T-DNA in the Genome of Transgenic High Oelic Rapeseed (Brassica napus L.)

In order to acquire the information about the insertion copy number and integration site of T-DNA in the genome of transgenic high oleic acid rapeseed ( Brassica napus L.), we isolated the genomic DNA from the transgenic line W-4, the T2 generation plants, then the transgenic genomic DNA was digested with Bam HI prior to conducting Southern bolt with the probe of a segment of NPT II labeled with Dig. The results showed that only one copy of T-DNA was detected to be integrated into the genome of transgenic line W-4. To isolate the flanking sequence of both right border and left border of T-DNA insertion in the genome, the thermal asymmetric interlaced PCR (TAIL-PCR) was employed by using three or four nested specific primers designed based on the sequence of the vector pCNFIRnos and a short arbitrary degenerate primer (AD1 or AD2) , respectively. The PCR products corresponding to flanking sequences of the right and left border were specifically amplified. The flanking sequence of right border is 470 bp in length which includes a 290 bp genomic sequence and a 180 bp vector sequence based on analysis of VecScreen, while the left border flanking sequence is 641 bp in length including a 365 bp genomic sequence and a 276 bp vector sequence. Further sequence alignment analysis revealed that the 180 bp sequence is identical to the RB border of pCNFIRnos vector, which exists a 62 bp deletion, whereas the later of 276 bp is better identical to the left border of pCNFIRnos vector besides a change from G to A happened. Therefore, it was suggested that the integration of the T-DNA in the genome of transgenic line W-4 should be a kind of vector backbone-free integration. Furthermore, there is no any information about homologous sequence of acquired flanking sequences found in the genome based on the Blastn analysis, which implied that the T-DNA should be integrated into non-coding region of the genome. In conclusion, we considered that the information about the T-DNA insertion copy number, integration site and flanking sequences in the genome of the transgenic rapeseed W-4 might be very useful for the biosafety assessment of genetically modified rapeseed and for the indentification of the transgenic high oleic acid rapeseed.
Synthesis of Sulfated Cyclodextrin Amphiphiles with Liposomal Encapsulation Properties

A novel class of amphiphiles with sulfate groups at the C-6 position and palmitoyl groups at the C-2, 3 positions of α-, β-, and γ-cyclodextrin (CD) were efficiently synthesized. These compounds formed stable monolayers with high collapse pressures at the air-water interface. The mixed monolayer behaviors of the 6-O-sulfated CD amphiphiles (SO3-CDC16) in the presence of dipalmitoyl phosphatidylcholine (DPPC) and cholesterol were discussed using the surface pressure-molecular area (π-A) isotherms. The collapse pressures showed maxima at molar ratios of SO3-CDC16 lower than 10 mol%. A morphological analysis of the liposomes containing DPPC and 4 mol% SO3-CDC16 formed in PBS was carried out using transmission electron microscopy with negative staining, and vesicles with maximum diameters of 350-500 nm were observed. Moreover, the releasing ability of these liposomes was examined using a fluorescent compound, calcein. It was clearly shown that liposomes containing SO3-CDC16 could release encapsulated calcein more easily than liposomes consisting only of DPPC, and that the release rate depended on the phase transition temperature of the SO3-CDC16 included in the liposome membrane.
New anvil designs in diamond-cells

New diamond anvils with conical support are introduced. Compared to conventional anvils the new design offers superior alignment stability, larger aperture, and reduced cost owing to significantly smaller anvil diameters. Except for table and culet, all surfaces are precision ground on a lathe, which lowers cost compared to faceted anvils. The conical design allows for steel supports, which are significantly easier and cheaper to manufacture than tungsten carbide supports. Conical support also prevents seat damage upon diamond failure. An additional new feature of the anvils is the roughened outer portion of the culet, which increases friction between the anvils and the gasket. This increases the height to diameter ratio of the pressure cell and prevents bonding between gasket and diamond, which causes ring cracks during pressure release. This technique replaces complicated diamond coating procedures. The anvils have been extensively tested for culets ranging from 0.1 to 1 mm diameter up to megabar pressures. A new anvil shape with cup-shaped culets to further increase the cell volume and gasket stability is also introduced.
Acute Toxicity and Blood Profile of Adult Clarias gariepinus Exposed to Lead Nitrate

Changes in Clarias gariepinus' blood cells were investigated after 96-h of exposure to lead. Ninety (90) Clarias gariepinus with average weight of 262.2g and average length of 30.8 were divided into 5 groups (A-E) at six (6) fish per group and in triplicates after being acclimatized for 14 days. They were then exposed to various concentrations (0, 25, 50, 100 and 200 mg/l) of lead nitrate for 96 hours. The 96-hour LC 50 was calculated to be 72.92; the packed cell volume (PCV) of the treatments decreased significantly relative to that of the control, while their platelet counts increased compared with the control. There was also a reduction in the RBC of treatments. Other blood parameters did not vary significantly in comparison to the control group, but it is worth noting that the mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) increased considerably in all treatments compared to the control. These alterations have been attributed to direct or feedback responses of structural damage to RBC membranes resulting in haemolysis and impairment in haemoglobin synthesis, stress related release of RBCs from the spleen and hypoxia, induced by exposure to lead. This study therefore gives an insight into toxic effect of acute exposure to lead on Clarias gariepinus.
Exploring the genetic diversity and substructure of the Portuguese cattle breed “Brava de Lide” using microsatellites

The genetic structure and diversity of nine ganadarias (the Portuguese word for bull farmer) of the Portuguese “Brava de Lide” (Bullﬁghting) breed were assessed with 30 microsatellites. Allelic richness per locus was low, with an overall average of 2 547. The mean number of alleles corrected for the size of the smaller sample ranged between 2,4 in ganadaria Jorge Mendes and 1,9 in ganadaria Vaz Monteiro. The mean expected and observed heterozygosities ranged between 0.627 in ganadaria Palha and 0.461 in ganadaria Vaz Monteiro and between 0.617 in ganadariaCabral D’Ascension and 0.4485 in ganadaria Vaz Monteiro, respectively. The ganadaria Vaz Monteiro was the one that systematically showed the lowest values of genetic diversity. To analyse the substructure among the 51 animals studied, a factorial correspondence analysis and a Bayesian approach were performed using the Genetix and STRUCTURE programs, respectively. The outcome of the factorial correspondence analysis resulted in the formation of four welldeﬁned clusters. On the other hand, the analysis with the STRUCTURE program has allowed us to obtain six well-deﬁned clusters. One well-deﬁned cluster corresponded to the oldest Portuguese ganadaria, the Vaz Monteiro. This ganadaria was established, at its inception in 1843, with bulls and cows of pure Portuguese caste and has been kept in the same family owing to its formation without the introduction of any other blood, constituting a unique caste that must be preserved, which is the true offspring of the Portuguese cattle breed “Brava de Lide”. In turn, the other clusters formed corresponded to the ganadarias Mario Vinhas, Murteira Grave, Nuno Casquinha, Palha and Jorge Carvalho.
Entrepreneurial marketing: a comparative case study of 42below vodka and Penderyn whisky

Entrepreneurial marketing has gained popularity in the entrepreneurship and marketing disciplines recently. The success of ventures pursuing non-traditional marketing approaches can be attributed to entrepreneurial marketing practices. Despite the multitude of marketing concepts and models, there are notable successes that deviate from these and are labelled “entrepreneurial. ” The purpose of this paper is to explore entrepreneurial marketing approaches used by companies and their impact on the success of marketing activities. We use the seven core dimensions of entrepreneurial marketing developed by Morris, Schindehutte, and La Forge (2002) and apply these to two spirit company cases: 42Below Vodka and Penderyn Whisky.
Pension Privatization and Country Risk

This paper explores how privatizing a pension system can affect sovereign credit risk. For this purpose, it analyzes the importance that rating agencies give to implicit pension debt (IPD) in their assessments of sovereign creditworthiness. We find that rating agencies generally do not seem to give much weight to IPD, focusing instead on explicit public debt. However, by channeling pension contributions away from the government and creating a deficit of resources to cover the current pension liabilities during the reform's transition period, a pension privatization reform may transform IPD into explicit public debt, adversely affecting a sovereign's perceived creditworthiness, thus increasing its risk premium. In this light, accompanying pension reform with efforts to offset its transition costs through fiscal adjustment would help preserve a country's credit rating.
Causality between wholesale price and consumer price indices in India

Purpose – The purpose of this study is to attempt to analyze Granger causality in the frequency domain framework between producers' prices measured by wholesale price index (WPI) and consumers' prices measured by consumer price index (CPI) in the context of India.Design/methodology/approach – Analysis was carried out in the framework of time series and for analysis Johansen and Juselius's maximum likelihood approach for cointegration was applied after confirming that variables are integrated of order one, i.e. I(1) through the Lee and Strazicich unit root test. Finally, Granger causality was tested in the frequency domain by utilizing a recently developed approach of Lemmens et al. over the period January 1957‐February 2009.Findings – The paper finds that CPI Granger cause WPI at a lower, intermediate as well as higher levels of frequency, reflecting very long‐run, intermediate as well as short‐run cycles. By contrast WPI Granger cause CPI at 5 percent level of significance was found at intermediate frequ.
‘ Data Centre to the Home ’ : Ultra-Low Latency for All

Data Centre TCP (DCTCP) was designed to provide predictably low queuing latency, near-zero loss, and throughput scalability using explicit congestion notification (ECN) and an extremely simple marking behaviour on switches. However, DCTCP does not co-exist with existing TCP traffic— throughput starves. So, until now, DCTCP could only be deployed where a clean-slate environment could be arranged, such as in private data centres. This paper proposes ‘Coupled Active Queue Management (AQM)’ to allow scalable congestion controls like DCTCP to safely co-exist with classic Internet traffic. In extensive tests within the edge gateway of a realistic broadband access testbed, the Coupled AQM ensures that a flow runs at about the same rate whether it uses DCTCP or TCP Reno/Cubic, but without inspecting transport layer flow identifiers. DCTCP achieves sub-millisecond average queuing delay and zero congestion loss under a wide range of mixes of DCTCP and ‘classic’ broadband Internet traffic, without compromising the performance of the classic traffic. The solution also reduces network complexity and eliminates network configuration.
The Policies and Practices of Good Governance in Indonesian Tourism: a Case Study in Malang, East Java

Good governance is a method to organize resources by involving the local community to participate and to supervise the development of the country. Good governance in tourism ensures that the industry can involve and benefit the local community. This paper aims to investigate the policies and practice of good governance in Indonesian tourism using the city of Malang in East Java as a case study. This is done by: (1) a study on the Regulation of the Major of Malang on the Master Plan of the Development of Regional Tourism no. 34 year 2014 and (2) field observations in the city of Malang. The research shows that the regulation has fulfilled six characteristics of good governance: participation, consensus oriented, equity and inclusiveness, effectiveness and efficiency, and accountability but fails to fulfill the three criteria of good governance: the rule of law, the transparency and the responsiveness. On the other hand, on the practices of the good governance, the city government lacks communication with the stakeholders and it is advisable that the city government set this forum in the near future to discuss the solutions to better tourism in Malang.
