Research on the Impact of Technological Innovation on Environmental Pollution -- Based on the Moderating Effect of Internet Development

Based on the provincial panel data from 2003 to 2015, this paper empirically investigates the impact of technological innovation on environmental pollution, and explores the moderating role of Internet development in this impact. It is found that technological innovation has a significant inhibitory effect on regional environmental pollution. The development level of the Internet has a significant regulating effect on the process of technological innovation affecting environmental pollution, which is manifested in that the improvement of the Internet development level can further enhance the inhibiting effect of technological innovation on environmental pollution and promote regional energy conservation and emission reduction. Based on the above analysis, this paper puts forward the corresponding countermeasures and suggestions.
Instructional Behaviors Affecting Student Attitudes Towards Science

ABSTRACT Community colleges are viewed as essential in the preparation of skilled science professionals in the U.S., and research regarding instructor impacts on student attitudes toward science are timely and relevant. This study explored specific instructor characteristics and pedagogical behaviors and their influence student engagement, confidence, and motivation to study science. A phenomenological approach was employed with elements of grounded theory. Data were collected from 12 community college students through semi-structured interviews. An explanatory framework for instructor characteristics that affected students’ academic attitudes focused upon engagement and confidence. Students’ impressions of instructors’ behaviors and attitudes reinforced the complexity of factors that affected their motivation. Instructors played a crucial role in building confidence, making disciplinary relevance explicit, and maintaining interest in science. Students valued instructors who were knowledgeable, caring, accessible, encouraging, and democratic. Students appreciated those who promoted a growth mind-set and autonomy, yet were still available as a supportive individuals. Future interventions should be implemented to address issues with the science course interest of community college students, and impacts on confidence and persistence. Informing instructors and policy makers that improvements in community college teaching techniques and support structures can enhance science attitudes is essential in students persisting in the pipeline, joining the STEM workforce, or transferring to four-year colleges. Understanding community college student characteristics can lead to customization of methods, objectives, and supportive policies to meet student needs, which may provide a well-equipped talent resource for participation in STEM careers.

Literacy development in EFL textbooks in Madrid’s primary schools

Research indicates that Spanish schools tend to focus on literacy in a narrow sense, as in the mechanics of reading and writing with a focus on text at the word and sentence level, while the idea of literacy on an international scale includes “the ability to use reading and writing skills in order to produce, understand, interpret and critically evaluate multimodal texts” (European Commission, 2012: 13). This study seeks to examine whether textbooks for English as a Foreign Language used in the fourth grade in Madrid take the more traditional approach to literacy or a broader one that involves the consideration of genre characteristics and work at the text level. A questionnaire was formulated to examine the reading and writing activities of four EFL textbooks. The results suggest that the books present a more narrow view of the concept of literacy. Key words: literacy, textbooks, English as a foreign language, primary education, bilingual education
Hydrophilic SiC hollow fiber membranes for low fouling separation of oil-in-water emulsions with high flux

The dry-wetting spinning technique involving immersion-induced phase inversion and dry-sintering was applied to prepare two types of SiC and Al2O3 hollow fiber membranes. The two hollow fiber membranes were characterized in terms of morphology and chemical surface composition by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), water contact angle and zeta potential measurements. The filtration capabilities of the two hollow fiber membranes were assessed by the separation of 200 mg L−1 synthetic (O/W) emulsions. During the treatment of O/W emulsions, the permeation flux of the SiC hollow fiber membrane was 163.9 L h−1 m−2, which was higher than that of the Al2O3 hollow fiber membrane (139.4 L h−1 m−2) at the beginning of the experiment. The membrane surface properties and the filtration results of O/W emulsion microfiltration demonstrated that the SiC hollow fiber membranes with a higher hydrophilicity had higher water flux and better anti-fouling properties.
Understanding the Impact of Open Defaecation on Child Diarrhoea and Nutrition Indicators

There are various individual factors that impact child diarrhoea-related behaviours among primary care seekers. Behavioural factors, social norms, economic considerations, access to healthcare, gender, etc., are some of the factors that can impact the treatment-seeking behaviour of the parents for their children who are suffering from diarrhoea. This article also establishes the relationship between open defaecation as a social behaviour and the incidence of child diarrhoea. Other than this, the relationship between open defaecation and child nutritional indicators is also established through substantive evidence. Open defaecation is known to have significant health impact, especially on children. Children from ODF distrcits are also significantly less wasted and under weighing than children from Non-ODF districts. However, the open defaecation free (ODF) status showed no significant impact on stunting in the current study.
Ilio inguinal neurectomy in inguinal hernia

“No disease of the human body, belonging to the province of the surgeon, requires in its treatment a better combination of accurate anatomical knowledge with surgical skill than Hernia in all its varieties”, Sir Astley Paston Cooper. A hernia is a protrusion of a viscus or part of a viscus through an abnormal opening in the walls of its containing cavity. The external abdominal hernia is the most common form, the most frequent varieties being the inguinal, femoral and umbilical, accounting for 75% of cases. Recently, with more attention to patient outcomes, chronic groin pain has replaced recurrence as the primary complication after open inguinal hernia repair. Several large series with systematic follow-up have reported pain rates ranging from 29% to 76%. Chronic pain following surgery has emerged as a common, and sometimes severe problem that can significantly affect a patient’s, health-related, quality of life. Treatment is often difficult and challenging.
The Impact of China’s Fiscal and Monetary Policy Responses to the Great Recession: An Analysis of Firm-Level Chinese Data

Abstract This paper investigates the effects of Chinese financial and fiscal policies designed to counter the worldwide Great Recession of 2008. We examine how policies designed to increase bank credit and health (i.e., asset liquidity, capital adequacy ratio, profitability, and bad loan ratio) influenced firm-level output, employment and investment. We also explore the impact of China’s expansionary fiscal policy with regard to these firm-level variables. We find that the policy effects varied based on firm-level characteristics such as size, liability ratio, profitability, ownership and the industry in which the firm operates. With respect to the dynamic effects, our results suggest that Chinese financial and fiscal policies were generally effective in the short run, but their positive impacts ceased within two years.
Economic Analysis of Factors Responsible for the Attainment of Food Security Levels among Beneficiaries of Selected Agricultural Cooperatives in the Limpopo Province of South Africa

ABSTRACT This study determined factors responsible for the determination of four levels of food security: never, seldom, sometimes and often or always among beneficiaries of two farmer cooperatives in the Limpopo Province of South Africa using the ordinal regression approach. A sample size of 178 respondents was used for the analysis. Respondents were purposively selected from beneficiaries of two cooperatives which had vegetable production as their main enterprise. Semi-structured questionnaires were used to collect information from respondents during the 2014/5 farming season. Data were analyzed using the SPSS version 22. Predictors which included, educational level, perceived high impact of cooperatives on food security, farming experience and ownership of equipment were identified as being positively associated with the odds of being food secure. It was recommended that for policy development and appropriate interventions in food security, factors identified to be positively associated with the attainment of high food security levels be considered as crucial.
Superficial Galactocelic Progression, Size-Variation and Assessment in a Patient

Breast cysts (galactocele) form in the mammary gland from ductal obstruction. Multiple pathologic entities may produce complex cystic breast lesions. Ultrasound is presently the first primary modality in breast evaluation after physical palpitation. We report a progressive case of multiple cysts in a 32-year-old woman, ranging from 28 mm to 20 mm. Though in-situ milk (sono-penic) appears sterile, the superficial presentation (externally) is that of a firm mass. Due to the known hazards of radioactive mammography, this case report proves the usefulness of sonar to image, map, measure, identify and diagnose breast pathology. In women with dense-heavy breast, ultrasound examination will play an important role in screening palpable and non-palpable masses.
Study of fine needle aspiration cytology evaluation of peripheral lymph nodes

Introduction: Lymph nodes are an integral component of the immune system and their enlargement is commonly noted in clinical practice in a wide spectrum of diseases, including infections like tuberculosis and malignancy. FNAC is an important diagnostic tool for rapid evaluation of mainly superficial lesions, especially of lymph nodes. It is cost effective, relatively less traumatic, and enables the pathologist to provide the clinician with a diagnosis in a very short time, and hence is ideal especially for OPD patients. Objectives: 1. To study the age and sex distribution of the patients of FNAC of peripheral lymph node. 2. To study the spectrum of diseases diagnosed on FNAC of peripheral lymph nodes. Methods: Cross-sectional hospital based Observational study. Total 50 patients who had superficial lymphadenopathy were included in this study. Male patients were 21 (42%) and Female patients were 29 (58%). FNAC was performed on this 50 patients. Diagnosis was made by light Microscopy. Result was tabulated and statistical analysis was done. Results: Male patients were 21 (42%) and Female patients were 29 (58%). 50 % patients were in the age group of 21 to 40 years. Reactive hyperplasia was 46% and Granulomatous lymphadenitis was 18%. Cervical lymph nodes were most commonly involved. Conclusion : FNAC is a simple, quick, low cost, minimally invasive and easy diagnostic procedure which is very much helpful in the diagnosis of diseases causing superficial lymphadenopathy in all age groups. Reactive hyperplasia of lymph node was the most common cytological diagnosis followed by Granulomatous lymphadenitis.

Adverse drug reaction monitoring of antitubercular drugs at tertiary care medical college hospital: prospective study

WHO defines ‘pharmacovigilance’ as the science and activities relating to the detection, assessment, understanding and prevention of adverse effects or any other drug related problems. Thalidomide disaster in 1961 was the landmark for establishment of the international drug monitoring programme. The safety profile of drugs is dynamic; new information is continuously assessed regarding use and outcomes. WHO Pharmacovigilance programme of India was started with the aim of generating the database among Indian population. Adverse drug reactions (ADRs) are one of the leading causes for mortality and morbidity worldwide. Which can also lead to the financial burden to the patients along with the treatment costs and on cost of healthcare delivery of the nation.
Use of Non-ophthalmic Ultrasound for Evaluation of Retinal Detachment in Patients with Opaque Media

Aim: To examine the accuracy of non-ophthalmic ultrasonography for detecting retinal detachment in eyes with opaque media.Methods: This was a prospective observational study conducted over a 1-year period. Eyes with opaque media in the form of a mature cataract, occluded pupils, or vitreous haemorrhage that precluded visualisation of the fundus were examined using non-ophthalmic ultrasound to detect retinal detachment. The clinical findings reported by the ophthalmologist were compared with the radiologist’s assessment.Results: Of the 95 eyes of 94 patients enrolled in the study, 86 had mature cataract, 7 had vitreous opacity, and 2 had eye trauma. Fifteen eyes (15.8%) showed evidence of posterior segment pathology on ultrasonography, with underlying conditions of retinal detachment (n = 7; 7.4%), posterior vitreous detachment (n = 5; 5.3%), asteroid hyalosis (n = 1; 1.1%), a vitreous traction membrane attached to the optic disc (n = 1; 1.1%), and intraocular foreign body (n = 1; 1.1%). Using non-ophthalmic ultrasonography, retinal detachment was detected in all 7 eyes, to achieve a sensitivity of 100% (95% confidence interval, 56-100%) and a specificity of 99% (95% confidence interval, 92-99%). Conclusions: Non-ophthalmic ultrasound is highly accurate for excluding retinal detachment, and may have a role in diagnosing retinal detachment in patients presenting with opaque media.
HVAC Corona Current Characteristics and Audible Noise During Rain

Corona Audible Noise is a major factor regarding the public acceptance of overhead lines. In this article, 2-conductor bundle is used to study the influence of rain on AC corona discharge. Rainfall is simulated by a large rain dispenser, which can be adjusted over a wide range. Using this experimental setup, the transient AC audible noise and corona current pulse characteristics under rainfall condition were studied. It was found that there are three different stages of audible noise level during rain, in which the audible noise level during the steady state stage is the highest. This transient characteristic could be explained by two different types of corona discharges for discharges above and below the conductor. Furthermore, the steady state audible noise level was studied under a wide range of rain rates and applied surface electric fields. It was found that the sensitivity of the audible noise level to the rain rate decreases with the applied electric field. This finding is of vital importance as the rain intensity is regarded as one of the most important factors influencing the HVAC audible noise, and a higher rain rate is usually considered to cause a higher audible noise level. A possible explanation of this phenomenon is attributed to the effect of a “critical number of corona sources”, which is well known from DC corona and possible evidence is provided based on long-exposure photos.

Structural Performance of Hybrid Timber Connections with Varying Bolt Patterns at Ambient and Elevated Temperatures

The research project presented in this study aimed to study the effect of bolt numbers and patterns on protected and unprotected concealed steel-glulam hybrid connections. Fifteen full-scale wood-steel-wood (WSW) connections were experimentally examined: five ambient and ten fire resistance experiments. Four and six steel bolts in two different patterns were arranged to form four different connection configurations that were experimentally examined. Also, each connection configuration was tested with and without fire protection of the steel components using wood plugs. Ambient specimens were tested under gradually increased monotonic loads until failure; whereas the other specimens were subjected to elevated temperatures that followed CAN/ULC-S101 standard fire, while being loaded to 100% of the ultimate design load capacity of the weakest connection configuration. The experimental results revealed that, the protected connections exhibited a failure time that is about 20 minutes more than that of the unprotected connections.
Crystal orientation dependence of alternating current photo-assisted (ACPEC) porous silicon for potential optoelectronic application

Porous silicon (PS) was successfully fabricated using an alternating current photo-assisted electrochemical etching (ACPEC) technique. This study aims to compare the effect of different crystal orientation of Si n(100) and n(111) on the structural and optical characteristics of the PS. ,PS was fabricated using ACPEC etching with a current density of J = 10 mA/cm2 and etching time of 30 min. The PS samples denoted by PS100 and PS111 were etched using HF-based solution under the illumination of an incandescent white light. ,FESEM images showed that the porous structure of PS100 was a uniform circular shape with higher density and porosity than PS111. In addition, the AFM indicated that the surface roughness of porous n(100) was less than porous n(111). Raman spectra of the PS samples showed a stronger peak with FWHM of 4.211 cm−1 and redshift of 1.093 cm−1. High resolution X-ray diffraction revealed cubic Si phases in the PS samples with tensile strain for porous n(100) and compressive strain for porous n(111). Photoluminescence observation of porous n(100) and porous n(111) displayed significant visible emissions at 651.97 nm (Eg = 190eV) and 640.89 nm (Eg = 1.93 eV) which was because of the nano-structure size of silicon through the quantum confinement effect. The size of Si nanostructures was approximately 8 nm from a quantized state effective mass theory. ,The work presented crystal orientation dependence of Si n(100) and n(111) for the formation of uniform and denser PS using new ACPEC technique for potential visible optoelectronic application. The ACPEC technique has effectively formed good structural and optical characteristics of PS.
Precision medicine for multiple sclerosis: an update of the available biomarkers and their use in therapeutic decision making

ABSTRACT Introduction: Precision medicine is an approach to disease prevention and treatment that takes into account individual variability in terms of genetics, environment and lifestyle. This approach depends on clinical, imaging and biological markers to define the optimal therapeutic approach for a given patient. Areas covered: Although many biomarkers have been proposed for MS, at present only oligoclonal bands (OCBs), magnetic resonance imaging, optical coherent tomography measurements and the JCv antibody index have been implemented in clinical practice. Expert commentary: Validation of biomarkers in multicentric prospective studies is necessary to improve the application of precision medicine for MS patients. New tools will open new avenues to improve our ability to provide personalized therapy to individuals with MS, including those aimed at the extraction of medical information from electronic health records, or those involving the application of machine learning tools to combine different types of information and biomarkers.
