The Economics Analysis of Small Scale Vegetable Production in North Central Namibia

In this paper, we attempted to identify determinants of farmers' participation in Green Scheme project and determinants of profits once farmers are in the project. Furthermore, we have attempted to investigate whether there is any difference in profitability between project farmers and other farmers operating own horticultural enterprises within the vicinity of the project. This paper has focused primarily on Etunda Green Scheme Project and other farmers in the Olushandja area. We used the Heckman's Sample Selection Model to address the issue of farmers' self-selection into the project. The study found that owning a car (proxy for wealth) and the project plot size are the most significant determinants of farmers' participation in the project. The study also found that the level of education and ability to hire labor are critical determinants of profitability for project farmers.
Effect of Cell Disruption Methods on Lipid and Fatty Acid Extraction from Microalgae

For biodiesel production, appropriate cell disruption method and device are key factors to increase the lipid extraction efficiency and yield; since the contents of the extracted lipid are determined by the disruption method and device [1]. Disruption methods such as microwaves, sonication, and bead-beating have already been used, but the most efficient method for microalgae has not yet been settled [1]. A range of mechanical and non-mechanical methods were tested to identify the most efficient cell disruption method for microalgae. Effect on fatty acid composition of the lipid by these methods was evaluated as well. The methods tested were: sonication, microwaves, autoclaving, acid lysis with 0.1M HCl solution, and akaline lysis with 0.1M NaOH solution. v The total lipids from Nannochloropsis EP1 and Chlorella vulgaris were extracted using a mixture of chloroform and methanol (1:2 v/v). The lipid samples were transesterified by alkali catalysis, 0.5 M sodium methoxide in anhydrous methanol for fatty acid extraction. High content of lipid extraction was achieved for both species under microwaves, autoclaving, and 0.1M HCl solution methods. Among these, 0.1 M HCl solution for Chlorella vulgaris and autoclave for Nannochloropsis EP1 was the most effective lipid extraction methods. In terms of fatty acid profiles from two microalgae, biodiesel from Chlorella vulgaris has better cold weather properties than the biodiesel from Nannochloropsis EP1 because of its high unsaturated fatty acid content. As a result of cost analysis of lipid extraction for Chlorella vulgaris, sonication was the most cost effective method for small volume of lipid extraction, while microwaves for large volume of lipid extraction. The highest amount of lipid extraction was achieved by 0.1M HCl solution method, but it showed the lowest cost efficiency for large volume of lipid extraction. On the other hand, microwaves appeared to be the most cost efficient method for large volume of lipid extraction.
Electronic Service Quality in Higher Education: Evidence from Albania

The purpose of this paper is to investigate the electronic service quality (e-SQ) offered by a higher education institution in Albania. Many universities are implementing web-based solutions to facilitate the delivery of their services, previously offered by appointed staff and physical facilities. These electronic services aim to increase the effectiveness of university's activities as well as to increase the convenience and the quality that both students and faculty receive. This study employs a modified E-S-Qual scale to measure the perceived service quality offered by a public university in Albania. Exploratory factor analysis and multiple regression analysis were used to confirm the proposed factor structure, while ANOVA served to measure the differences in e-SQ perceptions between students and faculty. The data analysis reveals interesting findings about the e-SQ offered by the university, as well as highlights the differences in perceptions between students and faculty. The study also affirms the E-S-Qual scale as a suitable instrument for measuring the e-SQ in higher education institutions. The results of the study are helpful for university management as they provide an overview of actual conditions of the quality the university offers and serve as a benchmark for further improvements. A limitation of this paper is that it focuses in measuring the e-SQ in a single setting. Nevertheless, this does not compromise the generalizability of the results and encourages the replication of this kind of study with further research.
A Comparative Application for Evaluating Composite Fabrics Used in Electromagnetic Shielding

Composite fabrics containing metal filaments are used widely for preventing electromagnetic radiation. Many experiments involving them are carried out continuously. Results are simulated in order to analyze their performance. Coding in Matlab is a popular method to compare the electromagnetic shielding properties of composite fabrics but for different options Matlab codes must be edited each time. Scientists who are not experts in coding have difficulties on editing such codes. To overcome this, an application written in C# in Visual Studio with . Net platform was developed. This application is integrated with Bunifu, which allows the application to be well designed. The proposed interface is user friendly and lets the user choose the available fabric with its stitch length from panel section. By setting options one can get the electromagnetic parameters such as scattering (S) parameters, reflection, transmission and absorption coefficients and total shielding effectiveness (SE) values with one click. As the application is integrated with Matlab codes, output is given as a Matlab graph with desired options. In this way the distinctions between the chosen fabrics can be analyzed easily.
Comparative Study: Dependability of Big Data in the Cloud

Cloud Computing provides computing resources remotely and on demand. These resources can be infrastructures, platforms, or application software. Whereas Big Data is well known for needing high capacity of both storage and computation's data streams. Thus, dependability must be studied in order to determine the attitude of Cloud systems to complete the features required by Big Data. The objective of this article is to deal with the general context of the Dependability and Cloud environment for Big Data. Thus, we carried out a statistic study of the research work that have been conducted in this context. The state of the art will allow us to approach the problematic of the dependability of Big Data in the Cloud. Our first objective is to know if there are many papers that deal at the same time a three thematics: the Cloud, the Big Data and the Dependability
Phylogenetic relationships within Cyeadaceae inferred from non-coding regions of chloroplast DNA.

The intrageneric relationships among 24 species of five Cycas sections based on the combined data of three non-coding regions of chloroplast DNA: trnS-trnG, psbM-trnD and trnL-trnF, were determined using Neighbor-joining, Maximum parsimony and Maximum likelihood methods. All three methods showed similar topology, which divided Cycas into several clades. The first clade consisted of two sections, Cycas and Indosinenses, while the other clades contained Asiorientales, Wadeanae and Stangerioides, which could not be resolved. This result indicated the polyphyletic group of Cycas sections. Base substitution patterns further revealed that the subsection Rumphiae of the section Cycas could be separated into two groups (C. rumphii and C. edentata). In addition, the high bootstrap demonstrated that C. taitungensis was closely related to C. revotuta, while two other species of the section Wadeanae (C. wadei and C. curranii) were closely related, which agreed with the morphology. Data analyses suggested that the trnS-trnG sequences were more informative than the psbM-trnD and trnL-trnF regions in addressing phylogeny. Short and moderate repeated sequences detected in this region also indicated the high rate of evolution in the Cycas species. The 14 bp tandem repeats identified in this study are the first to be reported on the non-coding chloroplast DNA of Cycas.
Tilburg University An Empirical Analysis of the Role of the Trading Intensity in Information Dissemination on the NYSE Spierdijk

Asymmetric information models predict comovements among trade characteristics such as returns, bid-ask spread, and trade volume on one hand and the trading intensity on the other hand. In this paper we investigate empirically the two-sided causality between trade characteristics and trading intensity. We apply a VAR-model for returns, bid-ask spread, trade volume, and trading intensity to transaction data on five stocks traded on the NYSE, covering the period August 1 until October 31, 1999. Similar to Dufour and Engle (2000), we find that the price impact of a trade is larger, the higher the trading intensity. Moreover, we establish significant feedback from the trade characteristics to the the trading intensity. Wide spreads, large volume, and high returns have a significantly positive impact on the trading intensity. We show that this feedback affects the price impact of large trades in transaction and in calendar time.
Exploration of binding mechanisms in nuclear hormone receptors by Monte Carlo simulations and X-ray derived motion modes

In the present study, we performed an extensive exploration of the ligand entry mechanism for members of the steroid nuclear hormone receptor family (androgen receptor (AR), estrogen receptor α (ERα), glucocorticoid receptor (GR), mineralocorticoid receptor (MR), and progesterone receptor (PR)) and their endogenous ligands. The exploration revealed a shared entry path through the helix 3, 7, and 11 region. Examination of the X-ray structures of the receptor-ligand complexes further showed two distinct folds of the helix 6-7 region, classified as “open” and “closed”, which could potentially affect ligand binding. To improve sampling of the helix 6-7 loop, we incorporated motion modes based on principal component analysis (PCA) of existing crystal structures of the receptors and applied them to the proteinligand sampling. A detailed comparison with the anisotropic network model (ANM, an elastic network model) highlights the importance of flexibility in the entrance region. While the binding (interaction) energy of individual simulations can be used to score different ligands, extensive sampling further allows to predict absolute binding free energies and analyze reaction kinetics using Markov state models (MSM) and Perron-cluster cluster analysis (PCCA+), respectively. The predicted relative binding free energies for three ligands binding to PR are in very good agreement with experimental results and the PCCA+ analysis revealed the importance of a peripheral binding site. Our analysis revealed that the flexibility of the helix 3, 7, and 11 region represents the most important factor for ligand binding. Furthermore, the hydrophobicity of the ligand influences the transition between peripheral and active binding site.
R-ESHAP as salvage therapy for patients with relapsed or refractory diffuse large B-cell lymphoma: influence of prior autologous stem-cell transplantation on outcome

We have read with interest the excellent editorial by Sud and Friedberg about salvage therapy for relapsed or refractory diffuse large B-cell lymphoma (DLBCL). [1][1] The authors cite and comment upon our recently published GEL/TAMO study which evaluates the influence of prior rituximab use on
Characteristics of Consumers Demanding and Their Willingness to Pay for Certified Safer Pork

A telephone survey of 609 Illinois households was conducted in spring 1999. Most consumers surveyed have concerns about pork safety. Concerns were greatest among households with children, lower incomes, older consumers, and Blacks. Lower consumption of pork was associated with higher concern. Consumers had more confidence in USDA certification of enhanced pork safety than in industry certification. Most consumers were willing to pay some price premium for a certified safer product. Those willing to pay more were more likely women, older consumers with incomes less than $70,000, who live in an urban household, and have concern about pork safety.

We hereby revise historical and recent information regarding Mycetarotes species for the first time, providing an identification key to workers, diagnoses, synoptic illustrated redescriptions of the species, including those of sexuals when known, updates of distributional records, and nest pictures of M. carinatus and M. parallelus. We comment the taxonomy and phylogenetic relationships among Mycetarotes and related genera, and on their geographical distribution. The available biological information on the genus is summarized.
Anisotropy Analysis of Turbulent Swirl Flow Anisotropy invariant map

Anisotropy invariant map proposed by Lumley and Newman and barycentric map proposed by Banerjee et al. were used in order to estimate the degree of anisotropy in turbulent swirl flow. The differences in visual interpretations of anisotropy states in these two maps were analysed and mathematical basis of these two maps was derived. Experimental data reveal that there is significant influence of swirl on the anisotropy of turbulence. Anisotropy invariant mapping shows that different flow regions of swirl flow are characterized by different anisotropy states.
A study to incorporate high protein content from tetraploid wheat (T. turgidum dicoccoides) to hexaploid wheat (T. aestivum vulgare)

Grain protein content of wheat is important for bread making and pasta quality. Wild tetraploid wheat (Triticum turgidum L. var. dicoccoides) has some genes for high protein content as a promising source. Three winter wheat cultivars of Colorado (Halt, Yuma, Akron) and one experimental line (CO99508) and one accession of T. dicoccoides were crossed to obtain backcrosses. The objective of this study was to determine higher protein content, SDSsedimentation and hardiness values in backcrosses T. aestivum x T. dicoccoides. Analysis of variance showed that highly significant differences were found among parents and backcrosses. The minimum and maximum values of grain protein content of all backcross populations changed from low protein parents (bread wheat cultivars) to high protein parent (T. dicoccoides). This increase in grain protein content of backcrosses is most likely due to the transferring of the high protein genes from the T. dicoccoides to the hexaploid cultivars. Although T. dicoccoides has high grain protein content, bread making quality of T. dicoccoides has lower than bread wheat cultivars. This situation has also been observed in all backcross populations. However, based on the results of this study, it could be concluded that high protein genes in the wild tetraploid wheat (T. dicoccoides) could possibly be transferred to the bread wheat cultivars.
Disentangling 2:1 resonant radial velocity orbits from eccentric ones and a case study for HD 27894

In radial velocity observations, a pair of extrasolar planets near a 2:1 orbital resonance can be misinterpreted as a single eccentric planet, if data are sparse and measurement precision insufficient to distinguish between these models. We determine the fraction of alleged single-planet RV detected systems for which a 2:1 resonant pair of planets is also a viable model and address the question of how the models can be disentangled. By simulation we quantified the mismatch arising from applying the wrong model. Model alternatives are illustrated using the supposed single-planet system HD 27894 for which we also study the dynamical stability of near-2:1 resonant solutions. From the data scatter around the fitted single-planet Keplerians, we find that for $74\% $ of the $254$ putative single-planet systems, a 2:1 resonant pair cannot be excluded as a viable model, since the error due to the wrong model is smaller than the scatter. For $187$ stars $\chi ^2$-probabilities can be used to reject the Keplerian models with a confidence of $95\% $ for $54\% $ of the stars and with $99.9\% $ for $39\% $ of the stars. For HD 27894 a considerable fit improvement is obtained when adding a low-mass planet near half the orbital period of the known Jovian planet. Dynamical analysis demonstrates that this system is stable when both planets are initially placed on circular orbits. For fully Keplerian orbits a stable system is only obtained if the eccentricity of the inner planet is constrained to $<0.3$. A large part of the allegedly RV detected single-planet systems should be scrutinized in order to determine the fraction of systems containing near-2:1 resonant pairs of planets. Knowing the abundance of such systems will allow us to revise the eccentricity distribution for extrasolar planets and provide direct constraints for planetary system formation.
Cytoplasmic Cyclin E Predicts Recurrence in Patients with Breast Cancer

Purpose: Low molecular weight cyclin E (LMW-E) detected by Western blot analysis predicts for reduced breast cancer survival; however, it is impractical for clinical use. LMW-E lacks a nuclear localization signal that leads to accumulation in the cytoplasm that can be detected by IHC. We tested the hypothesis that cytoplasmic staining of cyclin E can be used as a predictor of poor outcome in different subtypes of breast cancer using patient cohorts with distinct clinical and pathologic features. Experimental Design: We evaluated the subcellular localization of cyclin E in breast cancer specimens from 2,494 patients from 4 different cohorts: 303 from a prospective study and 2,191 from retrospective cohorts [NCI, MD Anderson Cancer Center (MDA), and the United Kingdom (UK)]. Median follow-up times were 8.0, 10.1, 13.5, and 5.7 years, respectively. Results: Subcellular localization of cyclin E on IHC was associated with full-length (nuclear) and low molecular weight isoforms (cytoplasmic) of cyclin E on Western blot analysis. In multivariable analysis, cytoplasmic cyclin E staining was associated with the greatest risk of recurrence compared with other prognostic factors across all subtypes in three (NCI, MDA, and UK) of the cohorts. In the MDA cohort, cytoplasmic cyclin E staining outperformed Ki67 and all other variables as prognostic factors. Conclusions: Cytoplasmic cyclin E identifies patients with the highest likelihood of recurrence consistently across different patient cohorts and subtypes. These patients may benefit from alternative therapies targeting the oncogenic isoforms of cyclin E. Clin Cancer Res; 23(12); 2991–3002. ©2016 AACR.
Bargaining over a climate deal: is it worse to wait and see?

Assuming that a North-South transfer is the key to climate cooperation, we ask when and how much the North should oer to the South in return for a commitment to reduce deforestation and forest degradation. In light of the risk of irreversible damage over time, we examine a negotiation with a deadline. We assess the conditions for an agreement to be immediate or delayed, and discuss situations likely to result in negotiation failure. Despite the risk of irreversible damage over time, we show that cooperation is likely to be delayed and characterize situations where North and South fail to agree within the deadline. Although Pareto-improving, cooperation may collapse because of ine¢ ciencies related to incomplete information. We show that in negotiations with a deadline, uncertainty about the bene…ts deriving from cooperation and the irreversibility of the damage that will be caused if cooperation is delayed, are the two key components aecting choice.
A Simple Method for Reducing THD and Improving the Efficiency in CSI Topology Based on SiC Power Devices

Silicon carbide (SiC)-based switching devices provide significant performance improvements in many aspects, including lower power dissipation, higher operating temperatures, and faster switching; compared with conventional Si devices, all these features contribute to these devices generating interest in applications for electric traction systems. The topology that is frequently used in these systems is the voltage source inverter (VSI), but the use of SiC devices in the current source inverter topology (CSI), which is considered as an emerging topology, generates interest. This paper presents a method for improving total harmonic distortion (THD) in the currents of output and efficiency in SiC current source inverter for future application in an electric traction system. The method that is proposed consists of improving the coupling of a bidirectional converter topology, voltage current (V-I) and CSI. The V-I converter serves as a current regulator for the CSI, and allows for the recovery of energy. The method involves an effective selection of the switching frequencies and phase angles for the carrier signals that are present in each converter topology. With this method, it is expected to have a reduction of the total harmonic distortion, THD in the output currents. In addition, a comparative analysis between converters with all-SiC technology and converters with hybrid technology is realized, to verify the impact of the SiC devices in the power converters efficiency.
Emergence of general relativity from loop quantum gravity: a summary

A model is proposed to demonstrate that classical general relativity can emerge from loop quantum gravity in a relational description of gravitational field in terms of the coordinates given by matter. Local Dirac observables and coherent states are defined to explore the physical content of the model. Expectation values of commutators between the observables for the coherent states recover the four-dimensional diffeomorphism algebra and the large-scale dynamics of the gravitational field relative to the matter coordinates. Both results conform with general relativity up to calculable corrections near singularities.
