Chemical Analysis of Some Wild Underutilized Mucilaginous Vegetables and a Domesticated Vegetable in Benue State, Nigeria

The chemical analyses of the vegetables; Abelmoschus esculentus, Ceiba pentandra, Cissus populnea and Corchorus oliterious were investigated to evaluate their nutritional potentials. The edible parts of the fresh and dried vegetables were pretreated and analysed for moisture, ash, crude; fibre, fat and protein as well as carbohydrate content while their energy values were estimated using standard methods. In addition, the mineral content was also evaluated using Atomic Absorption Spectrophotometric technique. The result indicated the following range for nutrients in fresh samples; moisture content Original Research Article British Journal of Applied Science & Technology, 4(32): 4566-4574, 2014 4567 (86.0to 67.97)%; ash content (2.58 to 0.74)%; crude fibre (15.60 to 2.17)%; crude protein: (0.01 to 0.39)% and carbohydrate (2.53 to 20.90) %. For dried samples the nutrient content in the same order ranges from (17.83 t0 10.39)%; (11.44 to 15.60)%; (39.95 to 25.54)%; (0.04 to 1.37)% and (30.84 to 53.71)% respectively. The energy values ranges from (46.2 to 325.5) kJ/100g and (531.9 to 864.4) kJ/100g in fresh and dried samples respectively. Magnesium was the predominant mineral element among those evaluated while Mn, Ni, Cd, Pb, Zn and Cu were found to be present in relatively low amounts with no clear trend. The wild vegetables were found to be of good nutritional quality having met most of the requirements of regulatory agencies. The values obtained in this study are also in agreement with other studies on vegetables and thus can serve as a source of nutrition therapy for people with certain ailments.
Effect of past behavioral experience on intention to use cervical cancer screening services among women in resources poor settings of Ethiopia: applicability of theory of planned behavior

Background: Despite; it’s effectively used to predicting the behavioral intentions of different health behaviors; the theory of planned behavior has been rarely tested in the context of low income countries. The current study has examined the effect of past behavioral experience on predictive applicability of theory of planned Behavior to intended use cervical cancer screening among women in resources poor settings. Methods: The study employed cross-sectional design enrolling 422 women visiting maternal and child health clinic. A structured questionnaire was used to collect data. The research was conducted under the framework of the theory of planned behavior to measure attitude, intention, perceived social and contextual influences. The SPSS version 21.0 was used to analyze the data. A hierarchal multivariable linear regression analysis was conducted to estimate the predictive power of the theory. The adjusted R-square and standardized regression coefficient were used to interpret the variance and effects of predictors on intention to cervical cancer screening respectively. P-value less than 5% was used to indicate significant associations. Results: The theory of planned behavior has explained variance in intention to use cervical cancer screening by 23.5% (R 2 =0.235). The inclusion of socio-demographic factors and past behavioral experiences into the model improved the prediction to 34.6% (R 2 = 0.349) indicating;11.40% of the prediction was attributed by factors external to theory. Subjective norm and attitude accounted for the highest and least variances in intention with 12.4% (R 2 = 0.124, F= 64.41, p=0.001) and 5.1% (R 2 = 0.051, F= 22.38, P=0.001) respectively. The past behavioral experience of using cervical cancer screening was significantly accounted for very small variances in intention with; 1% (R 2 = 0.01, F= 4.11, p=0.043) Conclusion: The past behavioral experience has small significant positive effect on the prediction. Intention to use cervical cancer screening among women can fairly be predicted by the application of theory of planned behavior. The predictive power of the theory could be improved with the inclusion of external factors like socio-demographic characteristics and behavioral experiences into the theory. Considering these factors while designing TPB based researches and health behavior change interventions is recommended.
Tuning of Metal Work Functions with Self‐Assembled Monolayers

Work functions of gold and silver are varied by over 1.4 and 1.7 eV, respectively, by using self-assembled monolayers. Using these modified electrodes, the hole current in a poly(2-methoxy-5-(2'-ethylhexyloxy)- 1,4-phenylene vinylene) light-emitting diode is tuned by more than six orders of magnitude (see Figure). Suppression of the hole current enables measurement of the electron current in a polymer/polymer blend photovoltaic cell.
Effects of Different Growth Regulators on Cadmium Accumulation by Sedum alfredii H.

Enhancing heavy metal accumulation in hyperaccumulator has been a hot topic. In the present study, the impact of plant growth regulators(PGRs)on growth and Cd accumulation of Sedum alfredii H. , a Cd hyperaccumulator, was investigated under hydroponic condition with 0.10 mmol·L-1Cd. Four kinds of PGRs were sprayed on leaves. Application of abscisic acid(ABA)increased shoot biomass and Cd concentration, thus enhancing Cd accumulation in shoots. Supplying indole-3-acetic acid(IAA)increased shoot biomass and improved leaf Cd detoxiation, thus promoting shoot Cd accumulation. Similarly, the treatment of 6-benzylaminopurine(6-BA)also enhanced shoot Cd accumulation due to improved shoot biomass and leaf detoxification. However, addition of ethylene(ETH)decreased shoot Cd accumulation as a result of suppression of both shoot growth and Cd upward transport. The results of present study indicate that proper applications of ABA, IAA, and 6-BA could improve Cd phytoextraction efficiency of heavy metal hyperaccumulators.
Macro factors in the returns on cryptocurrencies

This study investigates the relationship between expected returns on cryptocurrencies and macroeconomic fundamentals. Investors employ a lot of macroeconomic indicators for their investment decision, and hence adopting a few macroeconomic indicators is not sufficient in capturing a change in economic states. Moreover, due to aggregation, macroeconomic indicators are not measured precisely. To overcome these problems, we employ a dynamic factor model and extract common factors from a large number of macroeconomic indicators. We find that the common factors are strongly linked to the cryptocurrency expected returns at a quarterly frequency, while we do not observe this relationship using macroeconomic indicators such as inflation and money supply. This suggests that macroeconomic information matters in a longer term, which contrasts with the previous literature that explores a short-term relationship. The cryptocurrency prices are not determined by macroeconomic fundamentals in a short-term period since speculators impact the prices. However, in a long-term period, the prices are more linked to macroeconomic fundamentals.
DIVIDEND POLICY, PROFITABILITY AND CAPITAL TOWARDS BANKING VALUE

ABSTRACTResearch purpose – This study aims to test the influence of dividend policy, profitability, and capital on banking value. This research was conducted on banking financial sector companies included in the Indonesia Stock Exchange LQ45 index for the period 2015-2019. Methods – Samples were selected using a non-probability sampling method with purposive sampling. Data analysis with multiple linear regression techniques. Result – The results showed that dividend policy has no significant influence on the value of the company. Banking profitability also has no influence on the value of the company. Meanwhile, banking capital has a positive and significant influence on the company's value. The success of the company depends largely on the company's ability to raise capital, because insufficient capital will hinder the development of the company. Banking capital that continues to increase above the average banking standard shows the ability of banking capital is very good, this means that the ability of existing capital in the banking system is able to cover possible losses in credit activities and trading of banking securities. Limitations of research - There are two proxies, dividend policy and profitability policies that have not given evidence of the company's value and the small value of R2 is the material for further research. Originality - This study discusses the function of financial management as measured by financial decisions, and discussions on banks listed in LQ45 with variable testing separately.
Restoring and preserving capacity of self-affirmation for well-being in Indian adults with non-clinical depressive tendencies

BACKGROUND Although self-affirmation has been reported to enhance well-being and other positive life outcomes in normal adults, little is known about its capacity to restore and preserve well-being in adults with depressive tendencies. The current study attempts to expound the restoring and preserving capacity of self-affirmation for well-being in Indian adults with non-clinical depressive tendencies. PARTICIPANTS AND PROCEDURE The study used a sequential research design. Eighty participants (22-27 years) with depressive tendencies were chosen through purposive sampling and were randomly assigned equally to the experimental and control conditions. Their depressive tendencies and well-being were measured through standard scales at three intervals: pre-intervention, post-intervention and follow-up. RESULTS The results revealed significant restoring and preserving capacity of self-affirmation for the well-being of the experimental group participants as compared to the control group. The main effects of conditions (experimental, control) and treatment intervals (pre, post, follow-up) were significant along with the interaction effects of conditions × treatment intervals. The significant differences in the mean well-being scores for pre-intervention, post-intervention and follow-up points of time showed the restoring and preserving capacity of self-affirmation intervention. CONCLUSIONS The findings showed that self-affirmation helps to restore well-being as well as preserve it after a significant gap, which is evident in higher well-being mean scores of the experimental group taken at post-intervention and follow-up intervals. The positive effects of self-affirmation on well-being may have remained active even after the cessation of the intervention due to the underlying mechanisms of enhanced self-worth, positive values, inner strengths, positive attributions and interpersonal relationships.
Oxygen imaging at the sediment‐water interface using lifetime‐based laser induced fluorescence (τLIF) of nano‐sized particles

Most applications of laser induced fluorescence (LIF) for dissolved oxygen (DO) imaging in flowing water are based on luminescence intensity measurements of a dissolved indicator. A major limitation for applying the technique in the bottom boundary layer (BBL) is the sorption of the luminescent dye to organic surfaces at the sediment. Many sediment and soil studies have used planar optodes on transparent foils as an imaging technique for observing concentration distributions across the sediment‐water interface. The presence of the foil, however, is restricting the free flow and therewith the DO concentration above the sediment surface. In this study, we applied the phosphorescence lifetime LIF (τLIF) technique in combination with nanoparticles coated with platinum complexes as DO indicators. By using a planar laser light sheet for fluorescence excitation, the three‐dimensional flow field around the sampling area is not restricted. In contrast to the intensity‐based LIF technique, this method extracts the lifetime of the luminescence by evaluating the exponential decrease of the phosphorescence intensity after a short excitation light pulse. The method is therefore independent of dye concentration and is not affected by spatial inhomogeneities of the excitation light intensity. We applied the technique to visualize the burrow‐ventilation activity of the tube‐dwelling Chironomus plumosus larvae. Sequences of the two‐dimensional DO concentration distributions showed the intermittent outburst of highly‐depleted plumes from the outlet of the burrows, which mixed rapidly with the ambient oxygen‐rich water.
Risky Sexual Behaviour among Male Immigration and Correctional Personnel in Kano State, Nigeria, 2018

Background Worldwide, uniformed personnel have been recognized as a population at high risk for sexually transmitted infections because of their high mobility, power differentials and affluence. However, limited studies have been conducted on risky sexual behaviour (RSB) among male uniformed personnel in Nigeria. We conducted this study to determine the prevalence and identify the predictors of RSB among male immigration and correctional personnel in Kano State.Methods We conducted a cross-sectional study among 306 male immigration and correctional personnel using multi-stage sampling technique. A pre-tested self-administered structured questionnaire containing sociodemographic and variables associated with RSB was used for data collection. Indicators of RSB included transactional sexual intercourse, sexual intercourse with casual acquaintances and multiple non-regular sexual partners over the last 12 months. Data were analysed using descriptive statistics, Chi-square test and logistic regression (α=0.05). Results Mean age of the respondents in the immigration and correctional services was 37.9±9.3 and 38.0±8.1 years respectively. Overall prevalence of RSB was 15.1% (9.2% and 20.9% among correctional and immigration workers respectively). The identified predictors of RSB were service group, marital status and attending club house prior to sexual intercourse. The likelihood of RSB was lower among the correctional personnel (aOR=0.38, CI=0.17-0.80) than the immigration officers. Being married is protective of RSB (aOR=0.38, CI=0.18-0.81) while attending club house prior to sexual intercourse predisposes the uniform personnel to RSB (aOR=3.90, CI=1.30-11.68). Conclusions Risky sexual behaviour was highly prevalent among the investigated uniform men but was higher among immigration officers than the correctional personnel.
The effects of an educational program based on the Theory of Reasoned Action on high-risk sexual behaviors among patients with human papillomavirus infection: a randomized controlled trial

Background: Sexually transmitted diseases are a major health problem in all countries. Human papillomavirus (HPV) infection is the most common viral sexually transmitted disease in both genders. High-risk sexual behaviors (HRSBs) are among the major risk factors for HPV infection. Lack of knowledge can contribute to HRSBs and hence, education can potentially reduce HRSB risk. This study evaluated the effects of an educational program based on the Theory of Reasoned Action on HRSBs among patients with HPV. Methods: This two-group randomized controlled trial was conducted in 2017-2018. The educational program was developed based on the results of a survey into the most important components of the Theory of Reasoned Action contributing to HRSBs among 100 patients recruited from Razi hospital, Tehran, Iran. Then, 110 patients from the same hospital were consecutively recruited and randomly allocated to a control (n = 55) and an intervention (n = 55) group and all of them completed a demographic questionnaire and the Sexual Risk Scale. Then, each participant in the intervention group was provided with the developed educational program which consisted of two face-to-face educational sessions in the first and the thirtieth days of the intervention, an educational booklet, and biweekly follow-up telephone contacts. Their counterparts in the control group solely received routine care services. Three months after the first educational session, HRSBs were reassessed in both groups. Results: There were no significant between-group differences respecting participants’ baseline characteristics and mean score of HRSBs (P > 0.05). After the intervention, the mean score of HRSBs significantly decreased in the intervention group (P < 0.001) but did not significantly change in the control group (P = 0.70). The posttest mean score of HRSBs in the intervention group was significantly less than the control group (P = 0.015). Conclusion: Education based on the Theory of Reasoned Action is effective in significantly reducing HRSBs among patients with HPV infection. Nurses can develop and use educational interventions based on this theory to reduce HRSBs and HPV infection.

The impact of internal governance mechanisms on financial and stock market performance of listed companies: Evidence from an emerging market

The aim of this paper is to empirically test the impact of internal governance mechanisms on the financial and stock market performance of Moroccan listed companies. Board of directors’ characteristics such as independence and transparency, concentration, and presence of employees in the ownership structure, as well as some cognitive aspects of governance, represent the basis for discussion. Secondary data of a sample of 44 listed companies in the Casablanca Stock Exchange was analyzed using multiple linear regression. The results of this empirical study revealed that the financial and stock market performance of the companies that are captured by the return on equity (ROE) and the market to book ratio (M to B) significantly correlate with the adoption of the hybrid corporate governance approach. The relevance of this study is to enrich researches that deal with corporate governance and its impact on business performance in the context of Moroccan listed companies.
Using Multiple Representations to Resolve Conflict in Student Conceptual Understanding of Chemistry

Author(s): Daubenmire, Paul Lemuel | Advisor(s): Stacy, Angelica M | Abstract: Much like a practiced linguist, expert chemists utilize the power and elegance of chemical symbols to understand what is happening at the atomic level and to manipulate atoms and molecules to effect an observable change at the macroscopic level. Unfortunately, beginning chemistry is often taught in a way that emphasizes memorizing the symbolic representations of equations and reactions without much opportunity to meaningfully connect the observable macroscopic phenomena with an understanding of the chemistry taking place at the atomic level. The compartmentalized manner of chemistry instruction in most chemistry classrooms further nullifies the efficacy of the triplet relationship to connect between macroscopic observations, symbolic representations, and atomic scale views. If symbolic representations are presented as the goal of instruction, rather than as the means to gain understanding, then students will be impaired in developing a coherent understanding of chemical principles.This dissertation describes the development and implementation of an interview study to examine how undergraduate students interpreted multiple representations of a chemical equilibrium. To establish a baseline of ideas, students first were coached to verbally generate successive representations. They were then cued to think about the chemistry occurring between atoms and ions at the molecular level. Next, an experiment involving a change in states of matter and color was performed which paralleled the symbolic representations. Through self-explanations and verbalizing of conjectures, students were encouraged to explore, interpret, and refine their understanding of the observations related to the chemical symbols presented to them. Finally, with the goal of fostering a deeper understanding of the process of equilibrium, a dynamic visualization of the molecular level was introduced as a tool for helping students connect these multiple representations.This study revealed that one way in which students develop conceptual understanding and resolve conflicts between different representations of the same phenomena is by verbalizing their ideas as a conjecture (as a verbal explanation to advance towards a hypothesis). Thus, it is proposed that symbolic representations are most effective viewed not as an end goal but as a bridge for connecting macroscopic, visible phenomena with what is occurring at the molecular, invisible level. When the focus on merely memorizing chemical equations and symbols is removed, students can gain a coherent understanding of the meaning available when multiple representations are viewed together.
Preparation of Alumina Powders through Pyrocatechol, Resorcinol Mediated Sol-Gel Method

Ultrafine alumina powders were synthesized through pyrocatechol and resorcinol mediated sol-gel process. Aluminum nitrate was applied as the Al source and PVP was the dispersant. X-ray diffraction (XRD) study displayed that γ-Al2O3 powders formed in the range of 800-900 °C, and then γ-Al2O3 transformed to α-Al2O3 at higher temperatures, pure α-Al2O3 powders could be obtained at 1000 °C by using resorcinol as organic monomer. The results of transmission electron microscopy (TEM) revealed that Al2O3 nanoparticles with γ crystalline phase had grain sizes in the range of 5-40 nm. Scanning electron microscopy (SEM) observation displayed that the morphology of the prepared α-Al2O3 powders had aggregated bodies formed by Al2O3 grains in the range of 0.2-0. 5μm. These results provide a new way of preparation of alumina powders.
Clinical Utility of Ambulatory Blood Pressure Monitoring to Define Phenotypes of Hypertension

Clinic blood pressure (BP) remains the measurement for initial screening and management of hypertension, although there are recognized limiting factors, including accuracy of the measurement and the “white coat effect. ” Introduction of automated office BP overcomes these factors,[1] although the importance of out-of-clinic measurement with either home or ambulatory BP monitoring (ABPM) for confirming diagnosis of hypertension is recommended by clinical practice guidelines for Australia,[2] Europe,[3] the America,[4] and Canada. [5] The advantage of ABPM is that it allows multiple measurements of BP over 24 h period without patient intervention, ambulant, and during sleep and reveals variations in circadian BP profile which would have been missed with clinic alone. This brief review provides a summary of several of these different patterns which indicate specific BP phenotypes of hypertension, such as nocturnal hypertension and masked hypertension. Although there is specific guidance for physicians/health professionals for the measurement of ABPM,[6,7] patient satisfaction in wearing the equipment also needs to be considered[8-11] for reliability of the measures but also for engagement in their health and adherence to treatment. While ABPM is increasing in use in Australia, there are no reports on patient satisfaction and the results of a pilot survey are presented.
