A Linear Programming Model for Short Sea Shipping in the USA

Congestion, environmental impact, and fuel costs are factors that influence transportation decisions in both business and personal actives. As economies develop, transportation networks must adjust to accommodate the growing demand for freight transportation. Solutions that exploit underutilized transportation modes may be the best opportunity for minimal-impact growth. For example, redirecting freight that would otherwise be shipped on along the I-95 east-coast highway corridor to the east-coast marine highway corridors, would utilize untapped capacity. Necessarily, Short Sea Shipping, through the use of Ro/Ro vessels must be implemented in a cost-competitive manner. The environmental and congestion reducing benefits are considerable, however for the mode to gain acceptance, this transportation mode must at the same time be both competitive and profitable. A cost benefit analysis can estimate a projected profit margin and attract potential investors and businesses. By developing a mathematical model, the competitiveness of Short Sea Shipping is determined. The study finds that Short Sea Shipping can be both competitive and profitable when vessels carry 1,400 trailers over a distance of approximately 1,000 miles.
Board Diversity and Performance of Companies Listed in Nairobi Stock Exchange

This study examined the relationship between Board diversity and financial performance of firms listed in the Nairobi Stock Exchange. Data on Boards’ age, gender, educational qualifications, study specialization, and board specialization as well as the companies’ financial performance were obtained from 40 companies using a structured questionnaire. Using the Ordinary Least Squares (OLS) regression, the results show that there is a weak positive association between board diversity and financial performance. Overall, the results indicate a statistically not significant effect of board diversity on financial performance except for the independent effect of board study specialization on dividend yield. The results partially concur with agency and resource dependency theories of corporate governance as well as similar empirical studies. Ensuing implications for theory, policy and practice as well as methodology are also discussed.

A Review on Stimuli-responsive grafted membranes Based on Facile Synthesis Process and Extensive Applications

In the past few years, an increasing number of stimuli responsive thin polymer films and intelligent hydrogels have been reported in the literature for various biomedical applications, including drug delivery, tissue engineering and wound healing. The thermo-sensitive approach can be advantageous for some specific applications as it does not require organic solvents, co-polymerization agents, or an externally applied trigger for gelation. The conformation as well as change in physical properties of polymer brushes and polymer hydrogel can be influenced by the environmental stimuli, such as solvent composition, temperature, pH and electric fields. This review focuses on the recent advances of these stimuli responsive molecular thin film and stimuli responsive polymeric gels with unique properties and utilities. We also discuss some conflicting behaviors shown by polymer grafted membrane and polymer gel surfaces, synthesized by using same monomers. Major properties of stimuli responsive thin polymer films, and on their potential application in the field of nano-optics, ultrasensitive spectroscopies and other biomedical applications including drug delivery are also outlined.
The relation between dividends and insider ownership in different legal systems: international evidence

This paper provides new international evidence on the relationship between dividend policy and insider ownership by analysing a sample of USA, UK and Irish firms characterized by an Anglo-Saxon tradition and a matching sample of other EU companies from Civil Law legal systems. We hypothesize that, due to the different characteristics of both the legal system and the nature of agency conflicts in firms from those countries, the relation between dividend policies and ownership by insiders will be considerably distinct between the two sets of companies. We find that while in firms with an Anglo-Saxon tradition the relation between dividends and insider ownership follows the pattern negative–positive–negative, in Civil Law countries the relation is positive–negative–positive. These results are consistent with our hypotheses and breed new insights into the role of the dividend policy as a disciplining mechanism in countries with different legal systems and distinct agency problems.
Response of potato (Solanum tuberosum L.) to increasing growing season temperature under different Soil management and crop protection regimes in the upcountry of Sri Lanka

The national average potato yield of Sri Lanka is lower than its global average with the absence of an optimum temperature regime for tuber bulking being a major contributory factor. Increasing air temperatures due to the enhanced greenhouse effect have the potential to further reduce potato yields in Sri Lanka. Therefore, the primary objective of this study was to determine the response of phenology, growth and yield of potato to increasing temperature in the upcountry of Sri Lanka, which is the principal potato-growing region of the country. Furthermore, effectiveness of an integrated pest management (IPM) package and a modified soil management regime aimed at soil moisture conservation and reducing excessive use of synthetic pesticides and fertilizers were also tested. A field experiment was conducted during Maha 2012/2013 at Sita-Eliya (SE) and Rahangala (RG) of Sri Lanka, which represented a temperature increase of 5.2 °C from 15.1 °C to 20.3 °C. Potato (Solanum tuberosum L.) variety Arnova was grown with four treatments: T1 – Recommended crop management; T2 – Mulching with recommended crop protection (non- IPM) and fertilization (100 % inorganic fertilizer); T3 – Mulching with IPM and recommended fertilization and T4 – Mulching with IPM plus 25% of N provided as organic amendments. Crops matured a month earlier at the higher temperature site RG, i.e. in 81 days as compared to 111 days at SE. However, the thermal duration from planting to maturity was approximately similar at both sites (i.e. 1689 °Cd and 1662 °Cd at SE and RG, respectively). Crop growth rates were higher at RG, thus compensating for the lower crop duration so that total dry weights at harvest and tuber yields of T1 did not differ significantly between the two sites. At both sites, the tuber yield of T2 did not differ significantly from T1. The growth and yield response to mulching was greater at RG due to the lower rainfall and low soil fertility as compared to SE. The IPM treatments (i.e. T3 and T4) resulted in an effective control of the incidence and severity of late blight at SE but not at RG, where the prevailing temperature regime was optimum for spore formation of the late blight pathogen. Consequently, while the tuber yields did not show significant inter-treatment variation at SE, at RG the IPM treatments (i.e. T3 and T4) showed significantly lower yields than the non-IPM (T1 and T2) treatments. Analysis of the inter-relationships between tuber yield, yield components and growth data showed that potato yields of the present study were primarily source-limited.

Using Intra-Profile Information for Author Profiling Notebook for PAN at CLEF 2014

In this paper we describe the participation of the Laboratory of Lan- guage Technologies of INAOE at PAN 2014. We address the Author Profiling (AP) task finding and exploiting relationships among terms, documents, profiles and subprofiles. Our approach uses the idea of second order attributes (a low- dimensional and dense document representation) (4), but goes beyond incorpo- rating information among each target profile. The proposed representation deepen the analysis incorporating information among texts in the same profile, this is, we focus in subprofiles. For this, we automatically find subprofiles and build docu- ment vectors that represent more detailed relationships of documents and subpro- files. We compare the proposed representation with the standard Bag-of-Terms and the best method in PAN13 using the PAN 2014 corpora for AP task. Results show evidence of the usefulness of intra-profile information to determine gender and age profiles. According to the PAN 2014 official results, the proposed method was one of the best three approaches for most social media domains. Particularly, it achieved the best performance in predicting age and gender profiles for blogs and tweets in English.
A Feasible Flowchart to Screen EBV-Positive Diffuse Large B Cell Lymphoma of the elderly: A Molecular Approach

Background: Epstein Barr Virus-positive diffuse large B cell lymphoma of the elderly (DLBCL-EBV + - e ), initially described in 2003, is a provisional entity in the 4 th edition of the World Health Organization (WHO) Classification of tumors of hematopoietic and lymphoid tissues and is defined as an EBV + monoclonal large B cell proliferation that occurs in patients >50 years of age and in whom there is no known immunodeficiency or history of lymphoma. It is associated with a poor prognosis but could be treated with the association of novel therapeutic approaches. EBER in situ hybridization (EBER-ISH) is the gold standard assay for defining a tumor as EBV-related, however there are no uniform criteria for the percentage of EBV-positive cells in DLBCL-EBV + - e . Methods: We applied to Formalin Fixed Paraffin Embedded (FFPE) tissue of 43 novel DLBCL over 50 years Q-PCR for the detection of viral DNA in concert with EBER-ISH. Result: Only one case was defined as true DLBCL-EBV+- e being Q-PCR positive with a value of log EBV DNA/10 5 cells ≥ 6 and EBER-ISH positive. Conclusion: In the current study we applied to FFPE tissue of DLBCL-EBV + - e a reliable and feasible Q-PCR/EBER-ISH combined protocol for the screening of EBV status. Our protocol could help to better identify the DLBCL-EBV + - e patients eligible for novel therapeutic approaches.
Sinus rhythm restoration and risk of stroke in patients with persistent atrial fibrillation

__________________________________________________________________________ Background. The efficacy of oral anticoagulation in primary stroke prevention in pts with atrial fibrillation (AF) is well recognized. It is still unknown whether the strategy of cardioversion (CV) and efforts to maintain sinus rhythm (SR) in pts with persistent AF reduce effectively thromboembolic complications. Aim of the study was to assess impact of SR restoration on relative risk of systemic embolization episodes frequency in pts with persistent AF. Material and methods. How To Treat Patients With Chronic Atrial Fibrillation (HOT CAFE Polish Study) was designed to evaluate in randomized, multicenter and prospective manner risks and advantages of two therapeutical strategies in patients (pts) with chronic atrial fibrillation (CAF): rate control vs. rhythm control. Inclusion criteria were: pts age 50–75 years, CAF lasting from 7 days up to 2 years with etiology of arrhythmia related to hypertension, ischemic heart disease and hemodynamic insignificant valvular heart disease or lack of assessable etiology (idiopathic AF). Our study population comprised 205 pts (F/M 71/134; mean age 60.8 ± 11.2 year). Observation period was 12 months. Results. 104 pts (F/M 33/71; mean age 60.4 ± 7.9) were randomly assigned to rhythm control (Group II). At the end of follow-up, 63.5% of pts remained in SR. Anticoagulation therapy was considered in all 101 pts (F/M 38/63; mean age 61.4 ± 17.6) assigned to the rate control group (group I) and there were no thromboembolic complications observed. Three pts suffered ischemic strokes in the rhythm control arm (NS). Two of them (1.9%), both resulting in death, were observed on the third day following successful CV. The third stroke (0.9%) which was not disabling, affected a patient with AF recurrence. Conclusions. The strategy of SR restoration and maintenance in pts with persistent AF does not reduce the risk of thromboembolic complications.
Soil Stabilization as an Avenue for Reuse of Solid Wastes: A Review

Industrialization has resulted in rapid improvement in the standards of living; however, it has also resulted in pollution and generation of solid wastes that have recently reached epic proportions. An effective waste management alternative is the need of the hour. Reuse of waste materials have been advocated for quite a while now and the utilization of industrial wastes in improving the properties of poor soils open up a new avenue for solid waste management. Expansive soils have been one of the most problematic soils encountered by a Civil Engineer. A lot of techniques are available for stabilization of such poor soils including lime and cement stabilization. However, the utilization of solid wastes in soil stabilization is an area of potential and promise. And it also provides the double advantage of waste management along with soil improvement. With this as base, this paper attempts to review the various industrial wastes that have been adopted in soil stabilization as a standalone stabilizer without lime or cement, in order to shed light into the prospects of increased utilization of solid wastes in soil stabilization.
Detecting Tampering in Random Graphs

Let Gn = (Vn, En) be a growing sequence of deterministic finite graphs, with Vn denoting the vertices and En denoting the edges. Consider the random graph Gn(pn) = (Vn, En(pn)) obtained by including any given edge with probability pn, independent of other edges, and let P pn n denote the corresponding probability measure on Gn. Now tamper with the random graph in some regular way. For example, if Gn is the complete graph on n vertices, so that Gn(pn) is the ErdosRenyi graph, then one might tamper with it by disconnecting all the edges of a randomly chosen vertex, or by adding all the edges of a randomly chosen Hamiltonian path from Gn, or by adding all the edges of a randomly chosen clique of order kn from Gn. Denote the resulting induced measure on Gn by P pn,tamper n . The tampering is called detectable if limn→∞ ||P pn,tamper n −P pn n ||TV = 1, strongly undetectable if the above limit is 0, and weakly undetectable if {||P pn,tamper n −P pn n ||TV}n=1 is bounded away from 0 and 1. We study the tampering problem for a variety of examples.
Cloud Capacity Reservation for Optimal Service Deployment

Cloud computing is a profound revolution in the way it offers the computation capability. The Information Technology organizations do not need to oversize their infrastructure anymore, potentially reducing the cost of deploying their services. The main objective now is to reduce the cost of deploying a service in the cloud. Some research attempts have focus on deploying one service in multiple clouds, to benefit from different billing models. In this work, we propose a way to minimize that cost by using a single cloud provider with an optimal mixture of reserved and on-demand instances to take advantage of different billing models within the same provider. We tested this optimal combination of reserved and on-demand instances with real world workload traces. The results show a 32% deployment cost reduction compared to on-demand deployment.
New Oviraptorid Dinosaur (Dinosauria: Oviraptorosauria) from the Nemegt Formation of Southwestern Mongolia

Nernegtia barsboldi gen. et sp. nov. here described is a new oviraptorid dinosaur from the Late Cretaceous (mid-Maastrichtian) Nemegt Formation of southwestern Mongolia. It differs from other oviraptorids in the skull having a well-developed crest. the anterior margin of which is nearly vertical. and the dorsal margin of the skull and the anterior margin of the crest form nearly 90"; the nasal process of the premaxilla being less exposed on the dorsal surface of the skull than those in other known oviraptorids: the length of the frontal being approximately one fourth that of the parietal along the midline of the skull. Phylogenetic analysis shows that Nerncgtia ha,-sboldi is more closely related to Citipati osrnolskae than to any other oviraptorosaurs.
Finding the top conferences using novel ranking algorithm

An analysis of an academic network reveals interesting insights into the prevailing research domains. The scientometrics analysis of an academic network mainly focuses to find the top authors and top journals using Bibliometircs. There are few work identify the top conferences to help the scholars to know about the current trends in computer science and helps them to participate in the conferences to extend their interactions with other researchers. In this paper, we aim to find the top conferences in the computer science research domain. We present a novel algorithm, ConferencRank by adapting the state of the art Pagerank algorithm to rank the conferences. We use the various features as weights to rank the conferences as well. The proposed algorithm has been applied on a very large data set of the DBLP and the results confirm that the proposed algorithm is helpful to find the top conferences and ranks the conferences in a proper manner. As a future work, we will like to extend this work by finding topic-sensitive ranking of the conferences.
O 3-based nanocomposites employing graphene oxide : synthesis and sintering

A fast approach based on microwave technology was employed for the sintering of novel composites of alumina and using graphene oxide (GO) as susceptor. The thermal stability and structure of GO materials produced by chemical oxidation of graphite were characterized. The morphology, structure and mechanical properties of the composites sintered by microwave approach were reported to the counterparts sintered by conventional method. The results indicated the formation of an inter-connecting graphene network promoted the electrical conductivity in the composite having only 2 wt. % GO. Hardness and elastic modulus decreased significantly in samples sintered by conventional method due to lower values of density while microwave technology allowed to achieve a positive effect on the densification and showed a smaller grain size when compared to the one achieved by conventional heating.
Evaluation and Analysis of Distributed Graph-Parallel Processing Frameworks

Effect of Nonsaponifiable Fraction of Avocado Oil on Body Weight, Body Fat and Blood Lipid Profile of Broiler Chickens

Accumulation of body fat is the major problem associated with initiation of various diseases in fast growing broiler chickens. Methods to restrict the accumulation of body fat have met with limited success. The objective of this study was to evaluate the effect of Avocado Non-Saponifiable Fraction (NSF) in broiler chicken (from day 14 for 27 days) on body fat accumulation, growth performance, organ weight and plasma lipid profile. Supplementation of avocado NSF for 27 days has resulted in positive changes in plasma lipid profile with 50% decrease of abdominal fat and 33.8% increase in body weight compared with normal control chickens. The Avocado NSF improved body composition in broilers through higher lean-to-fat ratio and hence has a potential to improve overall health profile and reduce metabolic diseases in chickens.
