A STUDY ON THE EFFECTS OF GUIDED INQUIRY TEACHING METHOD ON STUDENTS ACHIEVEMENT IN LOGIC

This study sought to find the achievement levels of two groups of senior secondary schools students who were taught a difficult concept in Further Mathematics using two different methods; the Guided inquiry teaching method and the Conventional teaching method. A 25-items (20 objectives and 5 essay)type in mathematics test covering the algebra of logic in the four types of logic statements was administered on a sample of 197 students before and after the teaching. These students were randomly drawn from senior secondary schools in Jalingo Education Zone of Taraba state, Nigeria. The study which lasted for two months generated data that was analysed using mean, standard deviation and analysis of covariance (ANCOVA) with the pre-test scores as covariates at (P ≤ 0.05) probability level. The results showed that the students who were taught logic using the Guided inquiry teaching method had better achievement scores than students who were taught using the conventional teaching method.

On the relationship between empirical likelihood and empirical saddlepoint approximation for multivariate M-estimators

By comparing the expansions of the empirical log-likelihood ratio and the empirical cumulant generating function calculated at the saddlepoint, we investigate the relationship between empirical likelihood and empirical saddlepoint approximations. This leads to a nonparametric approximation of the density of a multivariate M-estimator based on the empirical likelihood and, on the other hand, it provides nonparametric confidence regions based on the empirical cumulant generating function. Some examples illustrate the use of the empirical likelihood in saddlepoint approximations and vice versa.

Detection of HOCO+ in the protostar IRAS 16293−2422

The protonated form of CO2, HOCO+, is assumed to be an indirect tracer of CO2 in the millimeter/submillimeter regime since CO2 lacks a permanent dipole moment. Here, we report the detection of two rotational emission lines (40, 4-30, 3 and 50, 5-40, 4) of HOCO+ in IRAS 16293-2422. For our observations, we have used EMIR heterodyne 3 mm receiver of the IRAM 30m telescope. The observed abundance of HOCO+ is compared with the simulations using the 3-phase NAUTILUS chemical model. Implications of the measured abundances of HOCO+ to study the chemistry of CO2 ices using JWST-MIRI and NIRSpec are discussed as well.
PRODUCED WATER FROM OFFSHORE OIL AND GAS INSTALLATIONS ON THE GRAND BANKS , NEWFOUNDLAND AND LABRADOR : ARE THE POTENTIAL EFFECTS TO SEABIRDS SUFFICIENTLY KNOWN ?

Chronic oil pollution is a preventable yet persistent source of increased adult mortality and decreased fecundity for seabirds (Ford et al. 1982, Butler et al. 1988, Piatt et al. 1990), two serious problems for organisms that typically have a life-history strategy of high adult survival, low reproductive success, and delayed recruitment (e.g. Weimerskirch 2002, Wiese & Robertson 2004, García-Borboroglu et al. 2006). Sources of chronic oil pollution include discharges from marine vessels, runoff, and accidental spills and operational discharges from offshore oil and gas activities (National Research Council 1985, 2003).
Physicochemical analysis of Lake Enriquillo in Dominican Republic

The water level in Lake Enriquillo in the Dominican Republic (DR) has increased by an unprecedented amount over the last decade, inundating thousands of acres of farmland and more than a dozen villages and inflicting adverse social, environmental, and economic impacts on the nation. The Lake Enriquillo Basin (LEB), located near the towns of Independencia and Bahoruco in the southwest region of the DR, is bordered to the north by the Sierra de Neyba mountain range and to the south by the Sierra de Bahoruco mountain range. Lake Enriquillo is hypersaline and endorheic, with a water level that normally fluctuates between 40–50 m below sea level (BSL). However, since 2000, both Lake Enriquillo and Lake Azuei (Sumastre) in Haiti have experienced alarming water level increases, with Lake Enriquillo’s water level rising to 17.2 m BSL This article explores the changes in some of the important physicochemical parameters—such as salinity, dissolved oxygen, temperature, and pH—that have occurred in the period from 1977 to 2012. The highest salinity value occurred in 2012, at a value 103.1‰, with an average increase of 27.06‰, coinciding with the lake level of 17.2 m BSL. Changes in these parameters have caused damage to the ecosystem and the lives of people and species that inhabit the region.

Low-Velocity Impact Properties of Sandwich Structures with Aluminum Foam Cores and CFRP Face Sheets

Within this contribution, the low-velocity impact behavior of sandwich structures was investigated. The sandwich structures consisted of carbon fiber reinforced polymer (CFRP) face sheets in various setups, and different core structures, including an open-cell and a closed-cell aluminum foam. The matrix of the face sheets was foamed polyurethane, which also acts as the adhesive connecting the face sheets to the core. Low-velocity indentation tests were carried out with multiple sandwich configurations. The indentation behavior was further examined by additional quasi-static indentation tests, and in situ indentation tests sequentially recorded by X-ray computed tomography. Both the low velocity indentation tests and the quasi-static tests were supported by digital image correlation measurements of the lower specimen surfaces. The overall indentation behavior was described consistently to sandwich structures with different material combinations in literature. The influence of each sandwich configuration parameter on the indentation behavior was determined and described in detail.
Point-by-point response to the reviews , list of all relevant changes made in the manuscript and a marked-up manuscript version

Atmospheric simulation chambers are exploratory platforms used to study various atmospheric processes at realistic but controlled conditions. We describe here a new facility specifically designed for the research on atmospheric bio-aerosol as 1060 well as the protocols to produce, inject, expose and collect bio-aerosols. ChAMBRe (Chamber for Aerosol Modelling and Bioaerosol Research) is installed at the Physics Department of the University of Genova, Italy, and it is a node of the EUROCHAMP-2020 consortium. The chamber is made of stainless steel with a total volume of about 2.2 m. The lifetime of aerosol with dimension from a few hundreds of nanometres to a few microns varies from about 10 to 2 hours. Characteristic parts of the facility are the equipment and the procedures to grow, inject and extract bacterial strains in the chamber volume 1065 while preserving their viability. Bacteria are part of the atmospheric ecosystem and have impact on several levels as: health related issues, cloud formation, and geochemistry. ChAMBRe will host experiments to study the bacterial viability versus the air quality level, i.e. the atmospheric concentration of gaseous and aerosol pollutants. In this article, we report the results of the characterization tests as well as of the first experiments performed on two bacterial strains belonging to the Gram positive and Gram negative groups. A reproducibility at the 10% level has been obtained in repeated injections and collection runs with 1070 a clean atmosphere, assessing this way the chamber sensitivity for systematic studies on bacterial viability vs. environmental conditions.
STATISTICAL MODELING AND ANALYSIS OF CHROMATIN INTERACTIONS

Chromatin interactions are of interest to researchers. A recent molecular technique, HiC, that uses formaldehyde cross-linking and paired-end sequencing, is able to detect genome-wide chromatin interactions. HiC can be modified to study the chromatin interactions mediated by a protein of interest. Chromatin Interaction Analysis by Paired-End Tag Sequencing (ChIA-PET) is also a technique for this purpose. However, these methods may also generate noise (product from random collisions of DNA fragments) in addition to signal (product from real interactions). Here we proposed a mixture model to distinguish real chromatin interactions from random collisions for the data from such experiments. The model is casted into a Bayesian framework to make use of a special feature of the data and information on protein binding sites and gene promoters to reduce false positives. We also proposed models for detection of chromatin interactions with different intensities between two samples, e.g., a cancer sample and a normal sample. A simulation study demonstrated the nice performance of the above models. The model for the one sample study has also been applied on real datasets and achieved nice results.
On Exponential Stability for a Class of Uncertain Neutral Markovian Jump Systems with Mode-Dependent Delays

The exponential stability of neutral Markovian jump systems with interval mode-dependent time-varying delays, nonlinear perturbations, and partially known transition rates is investigated. A novel augmented stochastic Lyapunov functional is constructed, which employs the improved bounding technique and contains triple-integral terms to reduce conservativeness; then the delay-range-dependent and rate-dependent exponential stability criteria are developed by Lyapunov stability theory, reciprocally convex lemma, and free-weighting matrices. The corresponding results are extended to the uncertain case. Finally, numerical examples are given to illustrate the effectiveness of the proposed methods.
Public Health Policies and Functional Property Claims for Food in Brazil

Specific regulations for functional foods began in Japan in the middle of the 80 s. Known as food for specific health use (FOSHU: foods for specified health use), these foods carry a label of approval from the Japanese Ministry of Health and Welfare [1]. The goal was to develop foods that would enable the reduction of expenses on public health, considering the high life expectancy in that country [2]. The term “functional foods” refers to processed foods, similar in appearance to conventional foods, consumed as part of a normal diet, but demonstrating physiological benefits and/or reduction in chronic diseases risk, in addition to its basic nutritional functions [1]. The principle was soon adopted worldwide [2]. In Brazil, functional foods were officially recognized in 1999, with the approval of specific legislation [3]. The designations of the claims, as well as the criteria for their approval vary according to the regulations of each country or economic block. Therefore, it is noteworthy considering the regulations of the intended market for the product.
Movies and TV Series Fragments in Mathematics: Epistemic Suitability of Instructional Designs

There are plenty of books, journals and online sites devoted to the relationship between mathematics and cinema, and its educational applications, whose interest is to explore the pertinence of the instruction processes that can be designed around this resource. Instead of watching a full production, mathematics teachers that include movies and TV series in their classroom sessions, usually show short fragments, so the first step should be to consider these fragments alone to identify the mathematical objects and the involved meanings and representations. For this purpose, we use some theoretical notions from the Onto-Semiotic Approach to research in mathematics education, applying them to three excerpts from a movie and to some typical tasks designed based on them. The analysis of the involved mathematical content allows to reflect about the epistemic suitability of the instruction process, in terms of how aligned they are with the institutional meanings. The results show that it is possible to achieve a high suitability level but, most importantly, that this kind of analysis promotes teacher reflection to design teaching and learning processes.
New Trends and Issues Proceedings on Humanities and Social Sciences

At least 20% of adults have very low numeracy (Bynner & Parsons, 1997) and about 5-8% of the population has severe specific Mathematical Learning Disabilities (Butterworth, Varma & Laurillard, 2011). Failure to acquire basic mathematical skills may have serious life-long consequences. Thus, it is important to find ways of enabling children with MLD to acquire numeracy skills. The present study involved 10 children in Grade 3 (7 to 8 years old), identified by their teachers as struggling with mathematics. They were assessed using the Dynamo Assessment, which provides a profile of strengths and weaknesses in important components of mathematics. Five children acted as controls, while the other five followed the Dynamo Intervention programme. The intervention lasted for eight weeks. All the children were subsequently re-assessed using Dynamo Assessment. The profiles of the children who had undergone intervention showed improvement in most components, while the control group did not.
Wood formation in Norway spruce on a lowland site in Slovenia in 2015 and comparison with other conifers all over Europe

We present xylem formation in Norway spruce (Picea abies (L.) Karst. ) in 2015 at Panska reka, near Ljubljana, Slovenia (ca. 46°00’N, 14°40’E, 400 m a.s.l.) with a temperate climate. The research was a part of a long-term project, which involves different sites and tree species. We measured the widths of cambium and the formation of xylem growth rings with differentiating cells in postcambial (PC) and secondary wall formation (SW) phases, and mature cells (MT). The results for 2015 were compared with those for previous years (2009–2011) in the same species and site, and with the published data from wood formation studies in conifers from all over Europe. The latter were used in two-factor regression models which confirmed the effects of latitude and altitude on the critical dates of onset, end, and duration of xylem production. The models thus helped us to predict/reconstruct phenology of wood formation in conifers in Europe.
Paediatric Appendicitis : An Analysis of 386 Cases

S U M M A R Y 386 paediatric patients with a preoperative diag­ nosis of acute appendicitis were analysed: 84% had acute appendiceal inflammation amongst which 110 had advanced appendicitis. Ages ranged from 2 days to 16yrs (mean: 10.4 yrs). 14 % of the cases had no abnormal laparotomy findings. Tlie minor complica­ tion rate was 8%; including wound infections and bronchopneumonitises, and the major complication rate was 2%; involving intestinal obstructions, in­ traabdominal abscesses, wound dehiscences and malignant hyperpyrexia. Tlie overall wound infec­ tion rate was 7%. Tliis rate went up to 24.5% in those patients with advanced and/or perforated appen­ dicitises. Tlie mortality rate was 0.8%. The mean duration of abdominal pain was 1.7 days for acute appendicitis, 3.6 days for perforated cases and 1.9 days for wrong diagnoses. 21% of the total had per­ forated appendicitis. Children less than six had a 59% perforation rate, and those older than ten years 14.9%; indicating that the rate of perforation is higher in young children. Tlie results suggest that early diag­ nosis and inten'ention may decrease morbidity and mortality.
Prospects of fatty acid profile and bioactive composition from lipid seeds for the discrimination of apple varieties with the application of chemometrics

The extracted oils from four apple seed varieties (Royal Gala, Red Delicious, Pyrus Malus and Golden Delicious) from Pakistan were investigated for their fatty acid profiles and lipid biactives by GC-MS. The oil contents in the seeds of the apple varieties ranged from 26.8-28.7%. The results revealed that linoleic acid (40.5-49.6%) was the main fatty acid in the Royal Gala, Red Delicious and Pyrus Malus seeds, and oleic acid (38.7-45.5%) was the main fatty acid in the Golden Delicious seeds. Palmitic acid (6.1-7.4%) and stearic acid (2.0-3.1%) were the dominant saturated fatty acids, besides the small amount of palmitoleic, heptadecanoic, linolenic, archidic, eicosanoic, and behenicacids. Sterols, tocopherols, hydrocarbons and some other minor components were also identified from the unsaponifiable lipid fraction. The variation among the results of both fatty acids and lipid bioactives for the four different varieties was assessed by principal component analysis, discriminant analysis and cluster analyses. The results conclude that both oil fractions could be applied as a useful tool to discriminate among the apple seed varieties.
Phytochemical screening using GC-FID and sub-chronic assessment of Hydroethanolic leaf extract of Ageratum conyzoides Linn on albino rats

Background: Ageratum conyzoides Linn finds application in ethnomedicine, hence there is need to evaluate its toxic effect. The present study investigates the phytochemical compositions and the subchronic assessment of the hydroethanolic leaf-extract of A. conyzoides on albino rats. Materials and Methods: Gas Chromatography Flame Ionization Detector (GC-FID) was used to determine the phytochemical composition of the plant while sub-chronic assessment was done using Haem Analyzer and Randox kits. Data analysis was done using ANOVA with Turkey’s Multiple Comparison Test using MiniTab version 14.0. Values were considered significant when p<0.05. Result: Nine alkaloids were detected with mitraphyline having the highest concentration (9.23mg/100g). Humulene exhibited 27.21mg/100g, highest compared to the 44 terpenes detected. Carotene had 23.4mg/100g out of the 10 carotenoids. A very high salicyclic acid concentration (77.15mg/100g) relative to the 11 phenolic compounds detected. Twenty one (21) flavonoids were detected and kaempterol had the highest concentration (19.11mg/100g). Six known hydroxycinnamic acids were detected and chlorogenic acid showed highest concentration (14.85mg/100g). There was no significant difference (p<0.05) between the weights of the control and test rats. The group C showed significant increase (p<0.05) in the weight of the liver, compared to the control, group A. increase in the other organs were not significant (p<0.05). Liver function indices did not show significant charge except for the total bilirubin (48.30±5.6mg/dl) and (38.36±5.2mg/dl) for groups C and A respectively at p<0.05. The renal function indices (creatinine and urea) did not exhibit significant change (p<0.05) between test groups compared to the control. Total blood protein increased but not significantly (p<0.05) in the test groups compared to the control. Total blood glucose decreased significantly (p<0.05) from 76.40±11.2mg/dl to 69.40±12.0mg/dl in groups A and C respectively. Conclusion: The above results suggest that Ageratum conyzoides is toxicologically safe at sub-chronic low doses and as such a good source of nutraceuticals.
Adaptation to the laboratory environment in Drosophila subobscura

Adaptation to a novel environment is expected to have a number of features. Among these is a temporal increase in fitness and some or all of its components. It is also expected that additive genetic variances for these fitness characters will fall. Finally, it is expected that at least some additive genetic correlations will decrease, from positive toward negative values.
How financial liberalization impacts stock market volatility in Africa: evidence from Nigeria

Understanding the impact of financial liberalization on stock market is important for decision making by investors. The neo-classical economists believe that financial liberalization reduces stock market volatility while the post-Keynesian economists argue that financial liberalization increases volatility of the stock market. This study investigates the effect of financial liberalization on the volatility of an emerging stock market in Africa, with particular focus on the Nigerian stock market. The estimation results reveal that financial liberalization has a significant positive impact on return volatility, thus indicating that it increases stock market volatility. Also, the study finds no evidence of asymmetry in the stock market.

Self-Efficacy and Self-Regulation as the Predictors of Use of Oral Communication Strategies in EFL Contexts

The present study aspired to systematically investigate the relationship among EFL learners’ Self-Regulation (SR), Self-Efficacy (SE), and their Use of Oral Communication Strategies (UOCS). To this end, 367 male and female undergraduate students, within the age range of 20 to 30 (Mage = 25) were selected based on convenience sampling strategy. They were asked to fill in three questionnaires, namely the Oral Communication Strategies Inventory (Nakatani, 2006), the Motivated Strategies for Learning Questionnaire (Pintrich, Smith, Garcia, & McKeachie, 1991), and the SE Questionnaire (Sherer, Maddux, Mercadante, Prentice-Dunn, Jacobs, & Rogers, 1982). Both parametric and non-parametric formulas were conducted to inspect the significance of the relationships. The results revealed that there was a significant and positive correlation between SR and UOCS, SE and UOCS, and SE and SR. Furthermore, a regression analysis revealed that only SR makes a strong statistically significant unique contribution to predicting UOCS (β = 0.682, t = 15.3, p = 0.0005). SE did not turn out to be a significant predictor of UOCS scores. The study concludes with a discussion on the obtained results followed by presenting some implications for EFL teachers, learners, and syllabus designers.
