An Assessment of the Level of Provision of School Health Services in Selected Secondary Schools in Calabar Municipality, Cross River State, Nigeria

Purpose: This study was conducted to assess the level of provision of school health services in selected secondary schools in Calabar Municipality. Methodology: Two hypotheses were formulated to guide the study. The study employed the descriptive survey design. The multi-stage sampling technique was adopted to select a total of 314 SS2 students, 100 teachers and 20 principals from 20 schools (10 public and 10 private) and 2 policy makers to make up the sample size of 436. A well validated questionnaire, key informant interview guides and observation checklist were used to collect both qualitative and quantitative data from respondents. Results: Population and independent t-test were used to test the two hypotheses formulated. The results of data analysis were presented in tables and figure. The result of the study revealed that a significant difference exist between the School Health Programme implementation guidelines and the school health services provided in schools and that school ownership significantly influenced the provision of school health services (P = 0.000 at 0.05 confidence level). Private schools were observed to have more of the facilities/personnel and thus provide more health services than the public schools (school clinics/sick bays were found in 10% public and 50% private schools, school nurse/doctor in 0% public and 30% private schools, pre-entry medical examination found on-going in 10% public and 90% private schools, health records book for recording cases reported by students and staff found in 10% public and 30% private schools). Recommendations: Based on the findings, recommendations made included: that copies of the School Health Programme policy and implementation guidelines be made a compulsory document for all schools to guide programme implementation and that the Government should see it as a matter of compulsion, for all schools to have a school clinic/sick bay with at least a health personnel to man it before permission will be given them to operate.

Deep radio imaging of 47 Tuc identifies the peculiar X-ray source X9 as a new black hole candidate

We report the detection of steady radio emission from the known X-ray source X9 in the globular cluster 47 Tuc. With a double-peaked C iv emission line in its ultraviolet spectrum providing a clear signature of accretion, this source had been previously classified as a cataclysmic variable. In deep ATCA (Australia Telescope Compact Array) imaging from 2010 and 2013, we identified a steady radio source at both 5.5 and 9.0 GHz, with a radio spectral index (defined as S? ) of ? = ? 0.4 ± 0.4. Our measured flux density of 42 ± 4 ? Jy beam? 1 at 5.5 GHz implies a radio luminosity (? L? ) of 5.8 × 1027 erg s? 1, significantly higher than any previous radio detection of an accreting white dwarf. Transitional millisecond pulsars, which have the highest radio-to-X-ray flux ratios among accreting neutron stars (still a factor of a few below accreting black holes at the same LX), show distinctly different patterns of X-ray and radio variability than X9. When combined with archival X-ray measurements, our radio detection places 47 Tuc X9 very close to the radio/X-ray correlation for accreting black holes, and we explore the possibility that this source is instead a quiescent stellar-mass black hole X-ray binary. The nature of the donor star is uncertain; although the luminosity of the optical counterpart is consistent with a low-mass main-sequence donor star, the mass transfer rate required to produce the high quiescent X-ray luminosity of 1033 erg s? 1 suggests the system may instead be ultracompact, with an orbital period of order 25 min. This is the fourth quiescent black hole candidate discovered to date in a Galactic globular cluster, and the only one with a confirmed accretion signature from its optical/ultraviolet spectrum.
Keeping up with the law: investigating lawyers’ monitoring behaviour

Purpose – The authors wanted to provide an enriched understanding of how lawyers keep up-to-date with legal developments. Maintaining awareness of developments in an area (known as “monitoring”) is an important aspect of professional’s information work. This is particularly true for lawyers, who are expected to keep up-to-date with legal developments on an ongoing basis. Design/methodology/approach – The authors conducted semi-structured interviews with a group of lawyers who authored and published current awareness content for LexisNexis – a large publishing organisation. The interviews focused on identifying the types of electronic, printed and people-based current awareness resources the lawyers used to keep up-to-date with legal developments and the reasons for their choices. Findings – The lawyers mostly used electronic resources (particularly e-mail alerts and an electronic tool that alerted them to changes in website content), alongside interpersonal sources, such as colleagues, customers and profe.
Triple plasmon resonance of bimetal nanoshell

In this paper, light absorption spectra properties of a bimetal multilayer nanoshell based on quasi-static approach are investigated. Comparing with silver-dielectric-silver and silver-dielectric-gold nanoshells, gold-dielectric-silver nanoshells have three intense and separated plasmon peaks which are more suitable for multiplex biosensing. Calculations show that relatively small thickness of outer silver shell and large dielectric constant of middle dielectric layer of gold-dielectric-silver nanoshell are suitable to obtain the triple plasmon resonance.
Health IT adoption, productivity and quality in primary care

Within the last decade, there has been a growing push towards the use of electronic medical records and health information technology (IT) within primary care physician practices. Despite financial subsidies, smaller practices remain reluctant to adopt these information systems. Using a nationally representative survey of physicians, this study explores the relationship between physician, practice and area attributes and the adoption of health IT systems. Controlling for these attributes, the analysis subsequently studies the relationship between health IT, physician productivity and perceived quality of care. It finds that smaller practices and physicians with lower incomes are less likely to adopt health IT systems and that adoption varies with the type of medical conditions the practice typically treats. With regards to productivity, health IT adopters are more likely to see fewer patients and spend a larger amount of time on each visit with marginal increases in time on administrative tasks and no differences in perceived ability to deliver quality health care.
School of Computing Computing and Information Systems

: Technology acceptance has been studied in different perspectives. Though a few empirical studies on acceptance of Web 2.0 as a social networking tool in teaching and learning exist, none of such studies exist in Nigeria which is the focus of this study. This paper reports on a pilot study that begins to fill this gap by investigating the perceptions, attitude and acceptance of Web 2.0 in e-learning of this country. Based on literature review and initial primary study, a conceptual model of 9 variables and associated hypotheses. The model was operationalised into a questionnaire that was used to collect data from 317 students from 5 universities. The findings that came from data analysis indicate that all the variables except motivation co-vary with intention to use Web 2.0 in e-learning in Nigeria. Some of the validated variables are perceived usefulness and prior knowledge. The major conclusions and recommendations include the utilisation of Web 2.0 facilities to stimulate participation in learning. This work will contribute to the body of knowledge on acceptance of Web 2.0 social networking tools in teaching and learning. It will aid management decisions toward investing better on technology so as to improve the educational sector. This research will also be beneficial in the social development of individuals, local communities, national and international communities.
Properties of SE pacific stratocumulus using MM-wave radars and other remote sensors

During the last two decades, marine stratocumulus clouds have been the center-piece of many theoretical/modeling studies (e.g. Bretherton and Wyant 1997) and field experiments (e.g. Albrecht et al. 1988; Albrecht et al. 1995). This type of clouds is mainly observed at low levels over the eastern side of the subtropical oceans, where the conditions (cool surface waters – warm, dry air subsiding aloft) favor the creation of a sharp temperature and moisture inversion that caps the Marine Atmospheric Boundary Layer (MABL) and leads to the trapping of the clouds at its top (Klein and Hartmann 1993). Both surfacebased cloud climatologies (Klein and Hartmann 1993) and satellite studies (Ramanathan et al. 1989) have clearly indicated the impact of boundary layer clouds on the global radiation budget; their high albedo results in a substantial decrease of the amount of solar radiation reaching the ocean’s surface, while their low altitude corresponds to a small air-sea temperature difference and thus, allows for little change in thermal radiation emitted to space. Although the role of stratocumulus clouds in affecting the radiation balance by cooling the ocean was recognized through early studies (e.g. Randall et al. 1984), the growing need of a more accurate representation in the Global Climate Models (GCMs) has engaged many scientists in the pursuit of a better understanding of their radiative, microphysical and dynamical properties, the thermodynamic structure of the MABL as well as the climatological variability of the respective areas (e.g. Stevens et al. 2003). One of the most prevalent stratocumulus cloud decks in the world is located over the subtropical southeast Pacific, extending about 1500 km offshore from the Equator to the latitude of central
A COMPARISON OF THE EFFECT OF COMPUTER AND MANUAL REMINDERS ON COMPLIANCE WITH AMENT AL HEALTH CLINICAL PRACTICE GUIDELINE by

The objective of this study was to evaluate the relative effectiveness of a computerized decision support system and a manual reminder system on the implementation of a Major Depressive Disorder clinical practice guideline in an outpatient mental health clinic. The study was a randomized clinical trial in which 76 patients were randomly assigned within clinician to one of the two experimental conditions. The first condition was a checklist inserted in the paper medical record, and the second was a computerized decision support system entitled the Case Walker. The CaseWalker reminded clinicians when guideline-recommended screening for mood disorder was due, ensured the fidelity of the diagnosis of Major Depressive Disorder with the Diagnostic and Statistical Manual, Fourth Edition (DSM-IV) criteria, and generated a progress note. The Case Walker, compared to the paper checklist, resulted in higher screening rates for mood disorder (86.5% vs. 64.1 %, p = .018) and more consistent application of DSM-IV criteria (100% vs. 5.6%, p < .001). Clinician acceptance of the CaseWalker was good, with three of four clinicians strongly preferring it to the paper checklist. Thus, computer reminders were shown to be superior to manual reminders in supporting the implementation of a depression clinical practice guideline in an outpatient mental health clinic. A previous review of the literature on reminder systems concluded there is insufficient evidence for the superiority of computer reminders over manual reminders. However, the results of the present study provide further empirical evidence that computer reminders are more effective than manual reminders. Further, this study is believed to be the first randomized controlled trial of the efficacy of computerized reminders in a mental health clinic.
A TANDEM FLUID QUEUE WITH GRADUAL INPUT

For a two-node tandem fluid model with gradual input, we compute the joint steady-state buffer-content distribution. Our proof exploits martingale methods developed by Kella and Whitt. For the case of finite buffers, we use an insightful sample-path argument to extend an earlier proportionality result of Zwart to the network case.
Ab initio electronic structure of thallium-based topological insulators

We analyze the crystal and electronic structures of Tl-based strong topological insulators TlSbTe2, TlSbSe2, TlBiTe2 ,a nd TlBiSe2 by using first-principles calculation results. The topological nature of these materials is characterized by a single Dirac cone at thepoint. Aside from the latter robust surface state (SS), we find trivial SSs at (around) the Fermi level for large momenta as well as deep trivial SSs at (around) � . The calculated energy cuts show an isotropic shape of the Dirac cone and a simple spin structure of the cone. The strong dependence of electronic structure on both optimization of the chalcogenide atom position in bulk and surface relaxations, as well as the slow convergence of the Dirac cone with respect to the film thickness, are discussed. The situation in the thallides is contrasted with results for isostructural indium compounds InBiTe2 and InSbTe2, the latter not being topological insulators.
DEVELOPMENT AND VALIDATION OF A NEW CAPILLARY ZONE ELECTROPHORESIS METHOD FOR THE ASSAY OF ONDANSETRON

An effective new capillary zone electrophoresis (CZE) assay has been developed for the determination of ondansetron hydrochloride and one of its impurities, ((3RS)-3[(dimethylamino)methyl]-9-methyl-1,2,3,9-tetrahydro-4H-carbazol-4-one) noted impurity A. Best resolution between the two analytes was achieved using a 35 mM phosphate buffer (pH 6.0) as running electrolyte, 20 kV applied voltage at 15°C, with direct UV detection at 216 nm; the migration times were 3.05 minutes and 3.3 minutes, respectively. The newly established method was validated with respect to linearity, precision, accuracy, selectivity, detection and quantitation limits. The proposed CZE method is simple, fast and reliable, with convenient results in the assay of ondansetron and its impurity in pharmaceutical dosage forms (injectable solutions).

Shoot tip cryopreservation by vitrification in Kaempferia galanga L. An endangered, overexploited medicinal plant in Tropical Asia

Shoot tips from the established in vitro shoot cultures of Kaempferia galanga L. , an endangered medicinal plant were successfully cryopreserved using the vitrification procedure. Effect of concentration of sucrose for preculture, vitrification treatment with PVS2(Plant vitrification solution 2) and recovery medium on cryopreservation of shoot tip meristems has been analyzed. Overnight preculturing of the dissected shoot tips in MS medium containing 0.4 M sucrose, osmoprotection with loading solution for 20 minutes, dehydration with PVS2 for 20 minutes at 0 oC were found to be optimum among the various treatments tested. The cryoprotected shoot tips upon rapid freezing in LN (liquid nitrogen) followed by rapid thawing produced 50-60% survival and 30-40% regeneration rates. Incorporation of GA3 (giberellic acid) in the post-thaw culture medium was essential to induce shoot emergence in the initial phase. Subculturing of the recovered shoot tips in MS medium supplemented with 1.0 mgl -1 BA (6-benzyl adenine) and 0.5 mgl -1 NAA (α-naphthaleneacetic acid) resulted plantlet production. The regenerated shoots grew to mature plants were free of any morphogenetic variation upon field transfer.
Evaluation of a new cavitation erosion metric based on fluid-solid energy transfer in channel flow simulations.

Although there have been extensive investigations characterizing cavitation phenomenon in fuel injectors, much is still unknown about the mechanisms driving cavitation-induced erosion, and how these complicated physics should be represented in a model. In lieu of computationally expensive fluid-structure interaction modeling, the Eulerian mixture modeling approach has been accepted as an efficient means of capturing cavitation phenomena. However, there remains a need to link the erosive potential of cloud collapse events with the subsequent material deformation and damage of neighboring surfaces. Even though several cavitation erosion indices have been proposed in the literature, no single metric has been identified as universally applicable across all injector-relevant conditions. The objective of this work is to identify parameters that characterize the erosive potential of cavitation cloud collapse mechanisms that are likely to occur within injector orifices. While a commonly employed cavitation erosion metric, namely the maximum local pressure, was found to provide indications of potential sites for pitting and material rupture from single impact events, no additional information could be determined regarding the material erosion process. To improve representation of the incubation period within the cavitation erosion process, a new metric was derived based on cumulative energy absorbed by the solid material from repeated hydrodynamic impacts. Through evaluation of predicted cavitation cloud collapse events in a channel geometry against available experimental data, the stored energy metric yielded insight into the erosive potential of recorded impact events. The stored energy metric provided a means to accurately predict the influence of flow conditions on the incubation period before material erosion.
Investigation of Brazil Current rings in the confluence region

[1] TOPEX/Poseidon-derived along track SHA, climatological temperature, and salinity fields were used within a two-layer scheme to estimate the depth of the 8°C isotherm in the southwestern Atlantic. These fields were used to monitor the formation and characteristics of the Brazil Current warm-core anticyclonic rings shed by the first meander trough after poleward excursions of the Brazil Current (BC). Results reveal that 40 warm-core rings were shed by the BC between January 1993 and October 1998. The observed lifetime ranges between 1 and 4 months, with a mean value of approximately 2 months. At any given time, two to three anticyclonic rings coexisted in the Brazil-Malvinas confluence region. Most of the rings drifted southward without coalescing with their parent current. Only four rings were identified as being reabsorbed by the BC front after they were shed. No evidence of propagation or absorption of these anticyclones into the eastern limb of the subtropical gyre was observed. These rings have a mean horizontal length scale of 55 km, mean upper-layer thickness of 260 m, and mean translation speed of 10 km d−1. Volume anomaly and available potential energy computations showed a mean value of 3.6 × 1012 m3 and 2.5 × 1015 J, respectively. The upper layer transport of the BC was also computed, and a relationship between variations in the southward transport and ring shedding activity was examined. Computation of the heat flux anomaly of the BC rings is estimated to be approximately 0.045 PW per annum. Compilation of these results indicates that warm-core rings created by meandering boundary current extensions in different regions are generally similar.

The system is the appropriate reliable energy solution. It greatly contributes to sustainable development of the remote areas.
Vocabulary Learning Promotion through English Subtitled Cartoons

Conspicuously, the purpose of this study was to survey the impact of subtitled cartoons on vocabulary learning improvement among EFL learners. Furthermore, 40 upper-intermediate learners which were attending to English classes were chosen after taking a placement test as a proficiency to ensure their homogeneity. Participants were assigned into two experimental and control groups, namely: a first class received subtitled cartoons and the second class cartoons without any subtitles. The experimental group watched two cartoons with English subtitles according to the level of that class and the control group again watched those cartoons by turning off the Subtitles. Research included a pre-test and a post-test in both groups. Participants took a pre-test containing new words selected from the cartoons. After six treatment sessions, the post-test was administered to the groups. Data were analyzed and in order to find the differences between the experimental and control groups, the researcher conducted UNI-ANOVA and independent T-test. In conclusion, the findings showed that participants in the experimental group with subtitled cartoons performed significantly better and learned more new vocabulary compared to the control group. Subtitling was the significant type of enhancing learners' vocabulary knowledge.
