Accessibility Evaluation and Performance Analysis of e-Government Websites in Nigeria

Accessibility issues in websites design have been receiving a lot of global attention till date. This is as a result of the importance that is attached to having a website that is not only accessible but also usable to all. Through the deployment of various websites by the state government in Nigeria, e-government services could now be easily accessed. Despite this, there is need to know the accessibility and performance of these websites. Hence, this paper evaluates the accessibility and performance analysis of the state government websites in Nigeria by using two online automated tools: TAW and site analyser. The aim is to test for their conformance with the Web Content Accessibility Guidelines (WCAG). Results from the study show that none of the websites evaluated totally conform to WCAG 2.0 standard. Also, the overall performance obtained shows that most websites tested are above average. The results also show that there is no significant difference in the performance of the websites among different states in the country.
Skim Milk Flocculation Concentrates White Spot Syndrome Virus in Seawater for Detection Using A Monoclonal Antibody Based Flow-Through Assay

Since its emergence, white spot syndrome virus has caused huge loss to shrimp aquaculture. However, these viruses are present in very low copy number in water and hence, concentrating them prior to detection is very much essential. In the present study, skim milk (0.01%) was employed for one step concentration of white spot syndrome virus from seawater under acidic (pH 3.5) and neutral (pH 7.4) conditions. The concentrated virus was detected using a monoclonal antibody based flow-through assay, RapiDot and compared its performance with Polymerase Chain Reaction (PCR). In an invitro experiment, the recombinant VP28 protein of white spot syndrome virus was flocculated successfully by skim milk in 50 mL measuring cylinders and detectable in both sub-surface and floc samples by RapiDot. Further, these results were validated by experimental infection studies using virus infected water for skim milk flocculation and detected the virus in floc samples 6 h earlier by RapiDot, compared to 1-step PCR. Overall, a simple method to concentrate white spot syndrome virus in water by skim milk flocculation for detection by RapiDot has been developed and may be adaptable to field conditions.
INTERMEDIATE TYPE OF BURKITT'S LYMPHOMA: A RARE CASE REPORT.

INTRODUCTION Burkitt lymphoma(BL) is a highly aggressive lymphoma first described by Dennis Parsons Burkitt in 1958.It is a childhood tumor but can also be seen in adults. Among Indian population it is a very rare malignancy accounting for only 0.76% of solid malignant tumor. There are three distinct forms of BL –:a) the endemic or African form, found in equatorial Africa and Papua New Guinea, b) the non endemic or sporadic form, found in areas such as North America, Northern and Eastern Europe and the Far East and Immunodeficiency associated form. An intermediate form may also be distinguished, and this occurs in areas such as Southern Europe, the Middle East and parts of SouthAmerica. Endemic form has a peak incidence in children between 3 and 8 years of age. Common site of disease presentation is the face, with multiple facial bone involvement. Sporadic form affects the older children, with mean age of 11 years. It is more likely to have leukemic or bone marrow involvement, and less likely to have jaw involvement. Common site of involvement beingabdomen. The distinction between different types is generally based on geographic location, association with Ebstein barr virus (EBV), clinical presentation, incidence, age at presentation and sex ratio. BL in India could be a variation between sporadic and endemic types in its clinical presentation. Here, we present a rare case report of sporadic form of Burkitt’s Lymphoma occurring in a young Indian boy presenting with the features of endemic Burkitt’s lymphoma.
Understanding Patients’ Meal Experiences through Staff’s Role: Study on Malaysian Public Hospitals

Background: One way to improve hospital food provision is certainly by understanding the management of hospital foodservices, but there is limited detailed information about staff roles in food provision in many hospitals around the world. Objective: The hospital meal experience of patients, a part of the services provided by hospitals, is becoming important. Therefore, the role of various hospital staff members was studied through their behavior, attitudes, and practices so as to understand how the foodservice system works to address patients’ food consumption. Methods: This qualitative research used the convenient sampling method. Data was collected by interviewing twenty hospital employees with different job scopes (nurses, doctors, dietitians, foodservice managers, and directors of hospital foodservices) in 6 public hospitals. Results: Themes such as providing familiar food, food as the motivational factor for consumption, empathy shown by staff, and influences of the eating environment were identified using content analysis. Conclusion: The viewpoints and experiences of key stakeholders facilitated the understanding of various factors involved in the provision of hospital food which affect patients’ decisions to accept and consume food.
A Modified Unequally Spaced Array Antenna Synthesis Method for Side Lobe Reduction

The aim of this paper is to demonstrate the application of Unequally Spaced Arrays (USAs) in decreasing side lobe level (SLL) in linear arrays. As well known, solving of a nonlinear equation is needed in USA antenna pattern synthesis. In this paper, an improved algorithm for USA antenna pattern synthesis is presented. This method is based on converting the array factor into a triangular system of equations capable to be solved using a recursive algorithm. This method has more accuracy and speed than reported similar analytical methods based on simulation results, which leads to lower SLL and simulation time. In addition, an improvement of 3dB beamwidth in comparison with uniform spaced array can be observed.
Inclusion-maximal integral point sets over finite fields

We consider integral point sets in affine planes over finite fields. Here an integral point set is a set of points in Fq where the formally defined Euclidean distance of every pair of points is an element of Fq . From another point of view we consider point sets over Fq with few and prescribed directions. So this is related to Rédei’s work. Another motivation comes from the field of ordinary integral point sets in Euclidean spaces E. In this article we study the spectrum of integral point sets over Fq which are maximal with respect to inclusion. We give some theoretical results, constructions, conjectures, and some numerical data.
Long-term application of clinoptilolite via the feed of layers and its impact on the chemical composition of long bones of pelvic limb (femur and tibiotarsus) and eggshell

Selected 120 layers, hybrid breed Bovans Goldline, were divided into two balanced groups: control (C) and experimental (E) group. The layers were raised in three-floor cage technology with automatic watering, manual feeding, in the environment with regulated lighting and thermal schedule. The actual experimental period started in the 22 nd week and ended in the 68 th week of age of the layers. In the period following the filling of the cages the layers received complete feed mixture N1, subsequently, until the end of the experiment, they received feed mixture N2. The feed mixtures for Group C and E were of the same composition, with the only difference that the feed mixture designed for the experimental group contained 1% of clinoptilolite (commercial additive ZeoFeed) as a substitute for the same portion of wheat. The layers consumed the feed mixtures and drinking water ad libitum. In the layers of Group E the intensity of egg laying increased by 1.1%, which corresponds to an increased number of laid eggs 3.08 per layer. The average weight of laid eggs was 66.3 ± 6.25 g in the layers of Group C, 65.6 ± 5.44 g (P ≤ 0.05) in the experimental layers of Group E. In Group E the consumption of feed mixture per one egg was 4.1 g lower when compared to the control. In 100% dry matter the eggshell of layers that received clinoptilolite (Group E), as opposed to Group C, had a statistically significantly higher ( P ≤ 0.01) content of crude protein, calcium and magnesium. Almost the same and insignificant difference in values was found in ash and phosphorus. The values of the same indicators were statistically significantly higher in both monitored bones (femur and tibiotarsus) (P ≤ 0.05; P ≤ 0.01) during the application of clinoptilolite (Group E), with the exception of P in femur, where an insignificant rise in the level of P occurred. The rise in the concentration of Mg in Group E was of particular importance: in femur by 50.4%, in tibiotarsus by 32.4%. If we compare the monitored values in femur and tibiotarsus, we can see that the levels of ash, Ca and P are higher in tibiotarsus, and the levels of crude protein and Mg are lower. The long-term application of clinoptilolite favourably influenced the lodgement of Ca, P, Mg and crude protein in the eggshell as well as in the bones ( femur, tibiotarsus), increased the egg production and reduced the consumption of feed mixture per one egg, while the good productive health of the layers was maintained.
Effects of Administration of CarnivoraTM on Clinical Signs in Cats After Repeat Challenge with Feline Herpesvirus 1

Feline herpesvirus 1 (FHV-1) infection is a common and highly contagious feline upper respiratory pathogen, and vaccinated or previously infected cats can become ill upon re-exposure. CarnivoraTM a is a nutraceutical product with anti-inflammatory and immune system modulating properties. The objective of this study was to determine whether cats receiving CarnivoraTM prior to FHV-1 repeat challenge, would have lessened clinical signs and viral shedding when compared to those cats receiving a placebo. Young adult cats previously inoculated with FHV-1 were randomized into either a treatment or placebo group approximately 1 year after the previous FHV-1 infection. Treatment or placebo was administered as recommended by the manufacturer for 56 days prior to FHV-1 challenge. Cats that were administered CarnivoraTM had significantly less clinical manifestations of disease when compared to the control group. The results of this pilot study suggest that CarnivoraTM is an immune modulator in cats and could play a role in lessening signs of FHV-1 infected cats when re-exposed to the virus. These effects could also be beneficial for the management of other infectious diseases in cats and warrant further study.
Molecular phylogeny of Indo‐Pacific carpenter ants (Hymenoptera: Formicidae, Camponotus) reveals waves of dispersal and colonization from diverse source areas

Ants that resemble Camponotus maculatus (Fabricius, 1782) present an opportunity to test the hypothesis that the origin of the Pacific island fauna was primarily New Guinea, the Philippines, and the Indo‐Malay archipelago (collectively known as Malesia). We sequenced two mitochondrial and four nuclear markers from 146 specimens from Pacific islands, Australia, and Malesia. We also added 211 specimens representing a larger worldwide sample and performed a series of phylogenetic analyses and ancestral area reconstructions. Results indicate that the Pacific members of this group comprise several robust clades that have distinctly different biogeographical histories, and they suggest an important role for Australia as a source of Pacific colonizations. Malesian areas were recovered mostly in derived positions, and one lineage appears to be Neotropical. Phylogenetic hypotheses indicate that the orange, pan‐Pacific form commonly identified as C. chloroticus Emery 1897 actually consists of two distantly related lineages. Also, the lineage on Hawaiʻi, which has been called C. variegatus (Smith, 1858), appears to be closely related to C. tortuganus Emery, 1895 in Florida and other lineages in the New World. In Micronesia and Polynesia the C. chloroticus‐like species support predictions of the taxon‐cycle hypothesis and could be candidates for human‐mediated dispersal.
Adaptive Kalman Filtering Based on Posteriori Variance-Covariance Components Estimation

There are different ways to construct adaptive Kalman filtering (AKF) algorithms. This paper proposes an innovative way to simultaneously estimate the variance matrix R of the measurement vector and the variance matrix Q of the process noise vector based on the variance-covariance component estimation by taking the advantages of the measurement residuals and the process noise residuals (Wang, 1997, 2009; Wang et al, 2009) and the measurement redundancy contribution (Ou, 1989). The core of the novel AKF algorithm lies in the projection of the system innovation vector into the three groups of residuals: the residuals of the measurement vector, the residuals of the process noise vector and the residuals of the predicted state vector exclusive of the effect of the process noise. The simulated and real GPS data in kinematic relative positioning mode were used to demonstrate the performance of the proposed adaptive Kalman filter. The results from the simulated datasets confirm to the simulated variance-covariance components well. The results from real kinematic GPS datasets are also provided and discussed.
Regional‐scale controls on dissolved nitrous oxide in the Upper Mississippi River

The U.S. Corn Belt is one of the most intensive agricultural regions of the world and is drained by the Upper Mississippi River (UMR), which forms one of the largest drainage basins in the U.S. While the effects of agricultural nitrate (NO3−) on water quality in the UMR have been well documented, its impact on the production of nitrous oxide (N2O) has not been reported. Using a novel equilibration technique, we present the largest data set of freshwater dissolved N2O concentrations (0.7 to 6 times saturation) and examine the controls on its variability over a 350 km reach of the UMR. Driven by a supersaturated water column, the UMR was an important atmospheric N2O source (+68 mg N2O N m−2 yr−1) that varies nonlinearly with the NO3− concentration. Our analyses indicated that a projected doubling of the NO3− concentration by 2050 would cause dissolved N2O concentrations and emissions to increase by about 40%.
A CMOS Morlet Wavelet Generator

The design and characterization of a CMOS circuit for Morlet wavelet generation is introduced. With the proposed Morlet wavelet circuit, it is possible to reach a low power consumption, improve standard deviation (σ) control and also have a small form factor. A prototype in a double poly, three metal layers, 0. 5μm CMOS process from MOSIS foundry was carried out in order to verify the functionality of the proposal. However, the design methodology can be extended to different CMOS processes. According to the performance exhibited by the circuit, may be useful in many different signal processing tasks such as nonlinear time-variant systems.
Hierarchical patch generation for multilevel statistical shape analysis by principal factor analysis decomposition

We present a framework for multi-level statistical shape analysis, applied to the study of anatomical variability of abdominal organs. Statistical models were built hierarchically, allowing the representation of different levels of detail. Principal factor analysis was used for decomposition of deformation fields obtained from non-rigid registration at different levels, and provided a compact model to study shape variability within the abdomen. To assess and ease the interpretability of the resulting deformation modes, a clustering technique of the deformation vectors was proposed. The analysis of deformation fields showed a strong correlation with anatomical landmarks and known mechanical deformations in the abdomen. Clusters of modes of deformation from fine-to-coarse levels explain tissue properties, and inter-organ relationships. Our method further presents the automated hierarchical partitioning of organs into anatomically significant components that represent potentially important constraints for abdominal diagnosis and modeling, and that may be used as a complement to multi-level statistical shape models.
Effective Wireless Scheduling via Hypergraph Sketches

An overarching issue in resource management of wireless networks is assessing their capacity: How much communication can be achieved in a network, utilizing all the tools available: power control, scheduling, routing, channel assignment and rate adjustment? We propose the first framework for approximation algorithms in the physical model of wireless interference that addresses these questions in full. The approximations obtained are at most doubly logarithmic in the link length and rate diversity. Where previous bounds are known, this gives an exponential improvement (or better). A key contribution is showing that the complex interference relationship of the physical model can be simplified, at a small cost, into a novel type of amenable conflict graphs. We also show that the approximation obtained is provably the best possible for any conflict graph formulation.
Climate–vegetation control on the diurnal and seasonal variations of surface urban heat islands in China

Remotely sensed surface urban heat islands (UHIs) have gained considerable interest in recent decades due to the easy access and the wall-to-wall coverage of satellite products. The magnitude or intensity of surface UHIs have been well documented at regional and global scales, yet a systematic evaluation of the temporal variability over large areas is still lacking. In this study, the diurnal and seasonal cycles of surface UHI intensities (SUHIIs) in China are examined using Aqua/Terra MODIS data from 2008 to 2012. Results show that the mean annual SUHIIs varied greatly in a diurnal cycle, characterized by a positive day-night difference (DND) in Southeast China and the opposite in Northeast and Northwest China. Also, the SUHIIs differed dramatically in a seasonal cycle, indicated by a positive summer-winter difference (SWD) in the day and a negative SWD at night, accompanied by the highly diverse DNDs across seasons and geographic regions. Northwest and Northeast China overall showed the largest DND and SWD (>3 °C), respectively. These diurnal and seasonal variations depend strongly on local climate-vegetation regimes, as indicated by a strong positive correlation between DND and precipitation (and air temperature) and a negative relationship between DND and vegetation activity across cities and seasons. In particular, SHUIIs were quadratically correlated with the mean annual precipitation across space, suggesting that there might be a threshold in terms of the effects induced by local background climate. Our findings highlight the importance of considering the temporal variability of UHIs for more accurate characterization of the associated ecological and social-economic consequences.
Distributional patterns and community structure of Caribbean coral reef fishes within a river-impacted bay

This study examined how riverine inputs, in particular sediment, influenced the community structure and trophic composition of reef fishes within Rio Bueno, north Jamaica. Due to river discharge a distinct gradient of riverine inputs existed across the study sites. Results suggested that riverine inputs (or a factor associated with them) had a structuring effect on fish community structure. Whilst fish communities at all sites were dominated by small individuals (<20 cm), diversity and total biomass were reduced with increased proximity to the river mouth. The abundance of all fishes, but particularly small-bodied, juvenile and herbivorous fishes was reduced in turbid water when compared to clear-water sites. Results strongly suggest that fluvial sediment inputs may play an important role in structuring fish assemblages even under intense fishing pressure.
Brain Drain: The Mere Presence of One’s Own Smartphone Reduces Available Cognitive Capacity

Our smartphones enable—and encourage—constant connection to information, entertainment, and each other. They put the world at our fingertips, and rarely leave our sides. Although these devices have immense potential to improve welfare, their persistent presence may come at a cognitive cost. In this research, we test the “brain drain” hypothesis that the mere presence of one’s own smartphone may occupy limited-capacity cognitive resources, thereby leaving fewer resources available for other tasks and undercutting cognitive performance. Results from two experiments indicate that even when people are successful at maintaining sustained attention—as when avoiding the temptation to check their phones—the mere presence of these devices reduces available cognitive capacity. Moreover, these cognitive costs are highest for those highest in smartphone dependence. We conclude by discussing the practical implications of this smartphone-induced brain drain for consumer decision-making and consumer welfare.
An In-silico Approach to Explore the Possible Multifunctional Neuroprotective Efficacy of Violacein against Ischemic Stroke

Introduction: Cerebral ischemia arise due to insufficient/ interrupted blood supply to brain and is accompanied by pathologies like degradation of extracellular matrix resulting in blood brain barrier disruption, intra cranial haemorrhage, activation of astroglial cells and hence death of neurons. In addition, oxidative stress and inflammation is common to all neurodegenerative diseases enhancing the harmful consequences of diseases. Matrix Metalloproteinases (MMP) are normally involved in extracellular matrix remodelling and are regulated while injury and inflammation in tissue. Over expression of MMP2 and MMP9 results in progression of ischemic conditions by extracellular matrix degradation thus compromising the structural integrity of Blood Brain Barrier (BBB) proving them a potent targets for the disease. Violacein (source: Chromobacterium violaceum), purple pigment from microbial origin is a bisindole have high anti-inflammatory, anti-oxidant, anti-bacterial, anti-cancer and anti-parasitic properties. Present study is to study the effective potential of violacein against cerebral ischemia. Methods and findings: Violacein’s ADMET (Absorption, Distribution, Metabolism, Excretion, Toxicity), properties were calculated and structural inhibition of MMPs through molecular docking was evaluated. Violacein resulted six H-bonds with MMP2 with high binding energy of -11.83 kcal/mol and two H-bonds with MMP9 with binding energy of -9.889 kcal/mol. The Ki values of violacein with MMP2 and MMP9 were 2.12 nM and 56.14 nM respectively which proved high affinity of violacein towards the target. Conclusion: Violacein with its high antioxidant and anti-inflammatory property can be a potent all round treatment for cerebral ischemia and demands extensive research.
