COMPARATIVE TOXICITY OF SOME COMMONLY USED INSECTICIDES TO COTTON APHID AND THEIR SAFETY TO PREDATORY COCCINELLIDS

Experiments were conducted in the laboratory to evaluate relative toxicity of six insecticides, viz., Spinosad 45 SC, Indoxacarb 15.8 EC, Emamectin benzoate 5 SG, Acephate 75 SP, Acetamiprid 20 SP and Imidacloprid 17.8 SL against cotton aphid Aphis gossypii Glover and different stages of predatory coccinellids. On the basis of LC 50 values, acetamiprid was the most toxic whereas; spinosad was the least toxic insecticide to cotton aphid. The order of relative toxicity of insecticides over spinosad was acetamiprid > acephate > imidacloprid > emamectin benzoate > indoxacarb, with their relative toxicity values being 82.28, 23.04, 16.18, 1.57 and 1.45, respectively. On the basis of LC50 values, spinosad was the safest insecticide for the different stages of the predatory coccinellids and acetamiprid was the most toxic followed by imidacloprid, indoxacarb, emamectin benzoate and acephate. But comparison of LC50 values of various insecticides in respect of various stages of predatory coccinellids vis-avis important aphid pest, Aphis gossypii indicated that acephate was relatively safe and indoxacarb was toxic for the predator. The neonicotinoids despite higher relative resistance showed very low LC 50 values which were much below their recommended concentrations.
Male Teachers' Perception of the Teaching Profession and Their Relationship with Students in Public Secondary Schools in Uyo, Akwa Ibom State, Nigeria

No meaningful learning can occur if those saddled with the responsibility of teaching do not show interest in the teaching profession. Hence the study sought to investigate male teachers’ perception of the teaching profession and their relationship with the students in public secondary schools in Uyo Local Government Area of Akwa Ibom Sate, Nigeria. One research question was formulated to guide this study. A Survey research design was adopted and a sample of 503 students was randomly drawn from the fourteen pubic secondary schools in Uyo Senatorial District. Questionnaire was used to collect the data, which was analysed using t-test. It was revealed that interest in the teaching job on the side of the male teachers led to cordial relationship with the students and positive attitude towards academics and school engagements. It was recommended that teaching qualification be made compulsory for teaching job seekers, adequate facilities be provided, rapid promotions, salaries and other benefits be paid when due.
Electronic Business in Saudi Organization

This paper is to shed light on the use of electronic business and mobile applications in Saudi organizations to perform their various activities. The paper examined the validity of a previous model that was found from the literature, to identify the most significant factors that affect the intention to adopt mobile electronic business within Saudi organizations. The research suggests and tests seven hypotheses on a population consists of employees in public and private sectors. Therefore, a regular random sampling procedure was used in which 256 respondents were identified.Structural equation modeling had been performed to analyze the collected data, giving more superior empirical results that led to reject five of the seven hypotheses. Results indicate that mobile electronic business features and opportunities as well as social influence both positively affect the intention to adopt mobile electronic business in Saudi organizations.

Norms of Reciprocation Exhibited by Polish Students in the Trust Game: Experimental Results

Norms of reciprocity and the level of generalised trust are components of the social capital of a society, which is argued to be associated with economic growth. This article presents results from a large scale study of Polish students based on the Trust Game, in which an initiator and respondent can obtain mutual benefits when the initiator exhibits trust in the respondent, who then expresses positive reciprocity. Based on these results, we investigate norms of positive reciprocation within the Polish student community. Analysis indicates that a large proportion of students seem to use one of four simple norms of reciprocation. In statistical terms, the level of reciprocation is rather well reflected in the expectations of the initiators.
Effect of a single bout of resistance exercise on zinc-α2-glycoprotein

Abstract Context Resistance exercise training has recently been considered as an effective type of training to increase energy metabolism and insulin sensitivity. However, mechanisms of the resistance training-induced improvements in energy metabolism and insulin sensitivity have not been fully understood. Zinc-α2-glycoprotein (ZAG), which is a novel adipokine, has beneficial effects on energy metabolism and insulin sensitivity. Objective We investigated the effect of a single bout of resistance exercise on the ZAG concentration. Methods Nine healthy men were enrolled. They performed a single bout of resistance exercise (bench press and leg press) consisting of 10 repetitions of five sets at 70% of maximum strength with 90-s rests in between sets. Blood samples were obtained before and after acute resistance exercise to measure the ZAG concentration. Results The serum ZAG concentration significantly increased following acute resistance exercise. Conclusion This result suggests that a single bout of resistance exercise may enhance the ZAG concentration.
Innovative start-up patenting: A new approach towards identification and determinants

There already exists broad literature investigating small and innovative firms in many respects. However, there have been few attempts to assess this group of firms' propensity to patent or its patenting activities. This paper intends to fill that gap. By applying a new approach to account for young and innovative companies' patents, this paper avoids an undercounting of small firm patenting, which has been a feature of most of the earlier studies. A data set is used that comprises information on R&D, capital stock, state promotion etc for 534 Thuringian firms in their first three business years. The results of the zero-inflated negative binomial regression analysis suggest that patenting is an activity of science-oriented, cooperative young firms that are conducting R&D even before the firm has been launched.
The usefulness of outcrop analogue air permeameter measurements for analysing aquifer heterogeneity: testing outcrop hydrogeological parameters with independent borehole data

Outcropping sediments can be used as easily ac- cessible analogues for studying subsurface sediments, espe- cially to determine the small-scale spatial variability of hy- drogeological parameters. The use of cost-effective in situ measurement techniques potentially makes the study of out- crop sediments even more attractive. We investigate to what degree air-permeameter measurements on outcrops of uncon- solidated sediments can be a proxy for aquifer saturated hy- draulic conductivity (K) heterogeneity. The Neogene aquifer in northern Belgium, known as a major groundwater re- source, is used as the case study. K and grain-size data ob- tained from different outcropping sediments are compared with K and grain-size data from aquifer sediments obtained either via laboratory analyses on undisturbed borehole cores (K and grain size) or via large-scale pumping tests (K only). This comparison shows a pronounced and systematic differ- ence between outcrop and aquifer sediments. Part of this dif- ference is attributed to grain-size variations and earth surface processes specific to outcrop environments, including root growth, bioturbation, and weathering. Moreover, palaeoen- vironmental conditions such as freezing-drying cycles and differential compaction histories will further alter the initial hydrogeological properties of the outcrop sediments. A lin- ear correction is developed for rescaling the outcrop data to the subsurface data. The spatial structure pertaining to out- crops complements that obtained from the borehole cores in several cases. The higher spatial resolution of the out- crop measurements identifies small-scale spatial structures that remain undetected in the lower resolution borehole data. Insights in stratigraphic and K heterogeneity obtained from outcrop sediments improve developing conceptual models of groundwater flow and transport.
Aspects related to the outcomes of the treatment, in international borders, of cases of tuberculosis as associated to comorbidities.

OBJECTIVE analyzing the aspects associated with case outcomes and the international border situation when it comes to patients with tuberculosis (TB) associated with comorbidities. METHOD exploratory descriptive epidemiological study, analyzing all new cases of TB with comorbidities reported in 2013 on SISNAN in the cities at the border of the state of Paraná and Paraguay. The variables used were: sociodemographic, clinical and operational. To analyze the data, descriptive analysis and the chi-square test were applied. RESULTS 227 cases of tuberculosis associated with comorbidities were reported and 70.9% were from cities bordering Paraguay. Alcoholism (22.0%) and AIDS (13.7%) were the most common comorbidities. The chi-square test presented a statistical association of border cities with negative outcomes and not performing directly observed treatments. CONCLUSION Through the study, it was possible to find that the location of border cities can be determinant for a negative outcome.

Hypertension and Its Impact on Stroke Recovery: From a Vascular to a Parenchymal Overview

Hypertension is the first modifiable vascular risk factor accounting for 10.4 million deaths worldwide; it is strongly and independently associated with the risk of stroke and is related to worse prognosis. In addition, hypertension seems to be a key player in the implementation of vascular cognitive impairment. Long-term hypertension, complicated or not by the occurrence of ischemic stroke, is often reviewed on its vascular side, and parenchymal consequences are put aside. Here, we sought to review the impact of isolated hypertension or hypertension associated to stroke on brain atrophy, neuron connectivity and neurogenesis, and phenotype modification of microglia and astrocytes. Finally, we discuss the impact of antihypertensive therapies on cell responses to hypertension and functional recovery. This attractive topic remains a focus of continued investigation and stresses the relevance of including this vascular risk factor in preclinical investigations of stroke outcome.

A generalized time fractional diffusion equation containing a lower order term of a convolutional form is considered. Inverse problem to determine the order of a fractional derivative and a kernel of the lower order term from measurements of states over the time is posed. Existence, uniqueness and stability of the solution of the inverse problem are proved.
CYTOGENETICAL EFFECTS OF ALUMINUM ON ROOT MERISTEM CELLS OF HELIANTHUS ANNUUS L.

Diferentes concentraciones de aluminio (5, 50 y 100 μM) y diferentes tiempos de exposicion (24, 48 y 72 h) se aplicaron a celulas meristematicas de girasol (Helianthus annuus L.), para investigar las alteraciones citogeneticas, en particular, dilucidar sobre la nucleolina. La nucleolina fue estudiada bajo el estres por aluminio, utilizando el metodo de tincion con plata y el metodo de inmunofluorescencia indirecta. Los resultados mostraron que el indice mitotico disminuyo progresivamente a medida que aumento la concentracion de aluminio o el tiempo de exposicion. Se observaron C-mitosis, puentes en la anafase y rigidez en los cromosomas en todas las celulas de la punta de la raiz tratadas con aluminio. Algunas particulas contienen argirofilas NOR asociadas a proteinas distribuidas en el nucleo de las celulas del apice de la raiz. La cantidad de este material granulado aumento progresivamente a medida que aumento el tiempo de exposicion. Finalmente, el material nucleolar se expulso desde el nucleo hacia el citoplasma. El resultado tambien indica que, en presencia de 50 μM de aluminio por 48 h, la proteina nucleolina se transloca desde el nucleolo al nucleoplasma y citoplasma, lo que sugiere que el aluminio altera la sintesis de ARNr e induce la localizacion celular anormal de la proteina nucleolar. El fuerte efecto toxico de aluminio en el nucleolo puede inhibir o detener la mitosis, y por consiguiente, inhibir el crecimiento de la raiz
Performance Optimization of a Six-Strand Tundish

The aims of the present study are to predict and improve inclusion separation capacity of a six strand tundish by employing flow modifiers (dams and weirs) and to assess the influence of inclusion properties (diameter and density) together with velocity of liquid steel at the inlet gate on the inclusion removal efficiency of a six-strand tundish. Computational solutions of the Reynolds-Averaged Navier-Strokes (RANS) equations together with the energy equation are performed to obtain the steady, three-dimensional velocity and temperature fields using the standard k-e model of turbulence. These flow fields are then used to predict the inclusion sepapration by numerically solving the inclusion transport equation. To account for the effects of turbulence on particle paths a discrete random walk model is employed. It was observed that with the employment of flow modifiers, the inclusion separation capacity of tundish increases without any large variation in the outlet temperatures. It is shown that inclusion properties and velocity are important parameters in defining the operating conditions of a six-strand tundish.
Formal Synthesis of Control Functions with Supremica

—Supremica is a tool for formal synthesis of discrete-event control functions based on discrete event models of the uncontrolled plant and speciﬁcations of the desired closed-loop behavior. By using formal synthesis of control functions the need for formal veriﬁcation is reduced since the control functions are computed to automatically fulﬁll the given speciﬁcations, that is, they are “correct by construction”. Formal synthesis is especially useful for applications where the system-requirements or the available hardware is changing frequently. The modeling framework in Supremica is based on ﬁnite automata extended with variables, guard conditions and action functions. In order to handle large scale problems Supremica uses compositional abstraction techniques, and binary decision diagrams. Since the modeling language and algorithms are generic these techniques are useful in many application areas including control functions implemented in hardware. Supremica has been used in a number of industrial research projects to synthesize control functions for industrial robots and ﬂexible manufacturing systems.
Empathizing, Systemizing, Intuitive Physics and Folk Psychology in Boys with Asperger Syndrome

The present study focused on empathizing, systemizing, intuitive physics and folk psychology in children with Asperger syndrome. 50 boys from Slovakia in the range from 6 to 18 years participated in the research follow-up. The inclusion criteria were the diagnosis of Asperger syndrome according to ICD-10 and normal intellect (WISC-III). The tests measuring EQ, SQ, intuitive physics and folk psychology were used. Control group consisted of 60 boys from primary schools and grammar schools aged from 6 to 18 years of age. The results pointed to poor performance in empathizing and high performance in systemizing in children with Asperger syndrome in comparison with the control group. The scores on intuitive physics test and folk psychology test confirmed our findings.

Guided tissue regeneration combined with bone allograft in infrabony defects: Clinical outcomes and assessment of prognostic factors.

BACKGROUND AND AIM Clinical data on the outcomes of guided tissue regeneration (GTR) is scarce. The aim of this retrospective cohort study was to evaluate the outcomes after GTR, their stability and the survival of the treated periodontal infrabony defects. MATERIALS AND METHODS Infrabony defects treated with GTR using a bioabsorbable membrane and a bone graft substitute with at least 1-year follow-up were included. Survival and regression analyses were conducted to evaluate the outcomes, their stability, and the retention of the teeth. The effect of recorded variables on clinical attachment gain (CAL) and tooth survival were assessed via Cox Proportional-Hazards Models and Multivariate Generalized Linear Models. RESULTS 175 treated defects were selected from a total of 641 charts. The average follow-up was 5.75 ± 4.6 years. At baseline, the mean CAL was 9.56 ± 1.93 mm with a mean pocket depth (PD) of 8.41 ± 1.42 mm. At the 1-year post-surgical recall, 3.55 ± 1.85 mm of CAL gain and 3.87 ± 1.87 mm PD reduction were observed (p<0.05). The 5- and 10-year survival rates of the treated teeth were 85.0% and 72.7%, respectively. Baseline PD, smoking, and membrane exposure were significantly related to CAL gain, whereas baseline CAL, age, frequency in maintenance visits significantly affected tooth survival. CONCLUSION Within the limitations of this study, data suggests GTR is a good option for the treatment of infrabony defects since it can improve both tooth retention rate and overall clinical outcomes.

A 4-Year Transition of Health-Risk Factors and Its Effects on the Prevalence of Hypertension Among a Cohort of 60,569 Sukhothai Thammathirat Open University students

Objective Rapid economic growth transformed Thailand from a developing to a newly industrialized middle-income country. This fuelled a transition in health-risk factors including an increase in the prevalence of hypertension, an important risk factor for mortality associated with heart disease and stroke. This study analyses changes in healthrisk factors and associated hypertension trends over a 4 year period in a large national cohort of Thai adults. Design and methods Data derived from 60,569 Sukhothai Thammathirat Open University students living all over Thailand and participating in the Thai Cohort Study by responding to mail-based questionnaire surveys in both 2005 and 2009. Results Overall, the prevalence of hypertension among cohort members increased from 5.0% in 2005 to 6.1% in 2009. Hypertension prevalence in 2009 was higher in both sexes, 7.6% vs 9.4% for males and 2.8% vs 3.4% for females. In both sexes, hypertension associated with increasing age, obesity, diabetes, high blood lipids and alcohol consumption. In males, hypertension associated with marriage, smoking and higher income. Conclusion In Thailand, hypertension prevalence is increasing and is associated with obesity, diabetes mellitus, high blood lipids and alcohol consumption. Smoking, being married and having a high income are associated with hypertension in males but not in females. Thais should be encouraged to exercise more and control weight, stop smoking, drink less alcohol and consume healthy low fat foods.

The influences of three different aromatic cytokinin derivatives [6-benzylaminopurine, meta-topolin, and 6-(3-methoxybenzylamino)purine-9-ß-D-ribofuranoside (MeOBAPR)] on in vitro multiplication and rhizogenesis of the wild service tree (Sorbus torminalis [L.] Crantz) were compared. The highest micropropagation rate (24 new shoots per explant after 3 months of cultivation) was achieved on media containing BAP. On the other hand, the best rooting microcuttings were those multiplied on a medium containing MeoBAPR. To compare these results with the levels of endogenous cytokinins in multiplied explants, a newly developed UPLC-ESI(? )-MS/MS method was used to determine levels of 50 cytokinin metabolites in explants cultivated 12 weeks on media supplemented by BAP and of the two other aromatic cytokinin analogs used. Several significant differences among the levels of endogenous cytokinins, extracted from the explants, were found. The concentration of BAP9G, an important metabolite suspected to be responsible for inhibition of rooting and acclimatization problems of newly formed plantlets, was found to be the highest in microcuttings grown on media supplemented with BAP. This agrees well with the results of our rooting experiments; the lowest percentages of rooted plantlets 6 weeks after transferring shoots on rooting medium were present on explants multiplied on BAP. In contrast, BAP was still the most effective for the induction of bud formation on primary explants. Levels of the most active endogenous isoprenoid cytokinins, tZ, tZR, and iPR, as well as Oglucosides were also suppressed in explants grown on BAP compared with those of explants treated with other cytokinin derivatives. This may be the result of a very high BAP uptake into the explants grown on this cytokinin. On the other hand, endogenous concentrations of cis-zeatin derivatives as well as dihydrozeatin derivatives were not affected. Differences in the production of another plant hormone, ethylene, that plays an important role in controlling organogenesis in tissue culture, were also observed among S. torminalis plantlets grown in vitro on media containing different cytokinins tested. The highest ethylene levels were detected in the vessels containing media supplemented with mT. They were two to four times higher compared with the production by the S. torminalis explants cultivated on other media used. Finally, the levels of free IAA were also determined in the explants. S. torminalis plantlets grown on media containing BAP contained the lowest level of auxin, which is again in good agreement with their loss of rooting capacity. The results found in this study about optimal plant hormone concentrations may be used to improve in vitro rooting efficiency of the wild service tree and possibly also of other plant species.
