The workplaces, where human activity takes place, is characterized by some complex factors that can affect the health of employees. These factors (temperature, humidity, noise, vibration, toxic substances, lighting, particulate matter etc.) can also be generalized as dangerous factors or workplaces hazards [1, 2, 3, 4]. In this article are presented some results obtained after workplaces hazards measurements in a production and sales bakery unit for the parameters: O2, SO2, CO, NH3, temperature, humidity, suspension powders, VOC. The values of the measured parameters particulate matter (0.17 mg/m3 - 0.30 mg/m3) respectively volatile organic compounds (0.8 ppm ÷ 21.1 ppm) were below the maximum allowable concentrations, which indicates a safe workplaces for employees. The other parameters measured values, respectively temperature and humidity, were between 22.100C - 29.20 °C for temperature and 47% - 53% for humidity.

Published: September 2019

This study was carried out in order to ascertain if the Okigwe red lump stone, found in South-eastern Nigeria, could be used as coarse aggregate in making structural concrete. The maximum compressive strength values, obtained at 28 days for red lump stone concrete were 13.72 N/mm2 at w/c ratio of 0.53 for mix ratio 1:2:4 and 8.74 N/mm2 for mix ratio 1:3:6, at w/c ratio of 0.55. These values were not up to 20 N/mm2 which is the ACI 318 (1995) recommendation for structural concrete. Therefore, Okigwe red lump stone must not be used in  making structural concrete using mixes 1:2:4 and 1:3:6.

Authors: HANANE FIKRI , TAOUFIQ FECHTALI , MOHAMED MAMOUMI
Published: September 2019

Structure-Toxicity Relationships have been studied for a set of 42 organophosphorous pesticides (OPs) through multiple linear regression (MLR) and artificial neural networks (ANN). A model with three descriptors, including: total lipophilicity [log (P)], widths radicals R1 [(LR1)] and R2 [(LR2)] has achieved good results in phase Training and phase prediction of toxicity [log LD50 (lethal dose 50, Oral rat)]. The linear model (MLR: n=40, r²=0.86, s=40 and q2 = 0.66) and non-linear model with a configuration [3-6-1] (ANN: r²=0.95, s=0.73 and q2 = 0.17) have proved very successful and complementary. The selected descriptors indicate the importance of lipophilicity and widths radicals R1 and R2 in the contribution of the toxicity of pesticides derived from OPs used in this study. This information is relevant for the design of a new model of non-toxic pesticides OPs.
PULSE WIDTH MODULATION TECHNIQUE FOR THE SPEED CONTROL OF M-PHASE AC MOTORS
Authors: EGWAILE JOEL OSARUMWENSE , ORIAHI MATTHEW
Published: September 2019

Thyristors are now widely used in many power electronics and motor driven applications and all the known methods of control are nothing but variations of either the phase angle firing control (PFC) or the pulse width modulation control (PWM). Each of these methods has its own benefits and disadvantages, but the pulse width modulation control method is, perhaps, by far, the most effective and costly method. Since PWM differs from phase firing control (PFC) in that the control action of PWM takes place only during the time of the firing pulse, this research seeks to develop a combination firing package that maximizes the benefits of the two methods. At first a thyristor is configured as a PNP-type power transistor latch with two ordinary NPN bipolar switching transistors. The power transistor is switched on by zero crossover firing and then switched off by phase angle delay firing. The performance of the model was evaluated and the dynamic characteristics of the motor, such as speed, current, voltage and the total harmonic distortion were carried via simulation. The results shows that by using the Modified PWM firing technique the speed of an m-phase induction motor can be controlled more effectively and reliably. The circuit is easy to implement and cost effective and may be patented and made available for commercial use.

CORRELATION BETWEEN SERUM LEVEL GALECTIN-3 AND EARLY REMODELLING INDICATOR OF LEFT VENTRICLE IN PATIENT WITH ACUTE MYOCARDIAL INFARCTION DURING PRE-PERCUTANEOUS CORONARY INTERVENTION
Authors: Mataram I Nyoman Indrawan , Aryadana Wayan , Lestari AA Wiradewi
Published: September 2019

Background: Coronary heart disease (CHD) is a leading cause of death worldwide. Acute coronary syndrome (ACS) is a spectrum of CHD. Left ventricle remodelling is one of the complication with the bad outcome either short-term or long term. Early remodelling process (within 0-72 hours) post infarction can be assessed by circulating biomarker (Galectin-3), echocardiography, coronary angiography, and clinically.

Objective: The aim of study is to know the correlation between serum level of Galectin-3 and early remodelling indicator in patient with acute myocardial infarction during pre-percutaneous coronary intervention. The parameters are LVEDV, LVEF, diastolic function component, TIMI flow, MBG, and presence of acute heart failure.

Materials and Methods: This cross sectional study was conducted in Sanglah General Hospital during March-May 2018. A 62 sample was determined consecutively.

Results: Bivariate analysis with Spearman correlation shows Galectin-3 correlated with LVEDV (r = 0,808; p= 0,000), E/e’ average (r = 0,297; p = 0,019), E/A ratio (r = 0,261; p= 0,041), and MBG (QuBE) (r = 0,647; p = 0,000). No correlation was found between Galectin-3 and LVEF Teich (r = -0,213; p= 0,097), LVEF Biplane (r = -0,226; p = 0,077), LAVI (r = 0,301; p = 0,170), e’septal (r = -0,079; p = 0,539), e’lateral (r = -0,092; p = 0,476), and TR Vmax (r=0,068; p=0,600). Chi square analysis shows no association between Galectin-3 and diastolic dysfunction left ventricle (OR= 1,032, p= 0,966, CI95%= 0,239-4,462), TIMI flow (OR= 1,032, p= 0,966, CI95%= 0,239-4,462), MBG score (OR= 0,264, p= 0,197, CI95%= 0,031-2,259), and acute heart failure (OR=0,577, p= 0,476, CI95%= 0,127-2,617). Multivariat analysis with multiple linear regression shows an increase in Galectin-3 has been proven associated independently with LVEDV, LAVI, E/e’ average, and E/A ratio. Multiple logistic regression shows Galectin-3 has not been proven independently with diastolic dysfunction, TIMI flow, MBG score, and acute heart failure. LVEDV is the best outcome that can be explained as its value influenced by constant, BMI, and Galectin-3 (R2 = 0,509).

Conclusion: Galectin-3 correlated with LVEDV, average E/e’, E/A ratio, and MBG (QuBE). There is an independent association between Galectin-3 and LVEDV, LAVI, average E/e, and E/A ratio. Early remodelling process within 0-72 hours post infarction was happened pre-PCI. Anti-remodelling (including anti failure) during early phase is strongly recommended in order to prevent worse outcome in short and long term.

Keywords: Galectin-3, early remodelling left ventricle, acute myocardial infarction, percutaneous coronary intervention.
Diagnostic Value Of Qtc Dispersion And And Qt Dispersion Ratio Changes On Stress Test In Detecting Significance Of Coroner Lesion In Stable Angina Pectoris Patients
Authors: Yeantesa Putri , Rasyid Hauda El , Syafri Masrul , Nindrea Ricvan Dana
Published: September 2019

Background : Treadmill exercise test remains an important method and often used in the initial evaluation of patients with chest pain and can be a filter for more expensive invasive diagnostic. Increased QT dispersion (QTD) occurs because of the heterogeneity of ventricular repolarization because transient ischaemia during a treadmill stress test can be a marker of coronary artery disease (CAD) and can improve the accuracy of exercise tests to diagnose CAD, but this parameter is still controversial.

 

Method : This is an analytic observational approach with a cross sectional study. Data was taken retrospectively at the Heart Center Installation at RSUP Dr. M. Djamil Padang, from March to April 2019, stable angina pectoris patient with a positive treadmill stress test who underwent coronary angiography as the subject. Bivariate analysis was performed on changes in QTcD (∆QTcD) and QTdR (∆QTdR) variables on the significance of coronary lesions by the chi-square method, after which a diagnostic test was based on receiver operating curve (ROC) analysis.

 

Study Result : There were 122 subjects and found that older age, male and smoking were more common in groups with significant coronary lesions. Cut off point for ∆QTcD is ≥13 ms with a sensitivity of 87,1% and specificity 85,2% and AUC 95,1%, while ∆QTdR ≥5.5% with sensitivity 85,7% and specificity 81,9% and AUC 90,5% are related to significancy of coronary lesion. Obtained subjects with significant lesions generally had a value of ∆QTcD ≥ 13 ms (p <0.001) and ∆QTdR ≥ 5.5% (p <0.001).

 

Conclusion : The use of ∆QTdR dan ∆QTdR parameters as ECG variables, which are easily obtained in evaluating stress tests, can improve the diagnostic accuracy of exercise tests. In addition, evaluation of ∆QTdR dan ∆QTdR can provide information about the incidence of CAD.

Published: September 2019

Worldwide, ischemic heart disease is the most common cause of death and its frequency is increasing. ST-segment elevation myocardial infarction or STEMIis as form of ischemic heart disease with the highest mortality rate.

Based on ESC (European Society of Cardiology) guideline 2017 for STEMI management, reperfusion therapywhich is primary PCI strategy is recommended over fibrinolysis within induced timeframes, but if timely primary PCI cannot be performed after STEMI diagnosis, fibrinolytic therapy is recommended within 12 hours of symptom onset in patients without contraindications. In fibrinolytic therapy, oral aspirin should be given, and Clopidogrel is indicated as an addition to aspirin. Although Clopidogrel is a recommended P2Y12receptor inhibitorin fibrinolytic therapy,PERKI guideline 2018 in ACS management also mention thatswitching to Ticagrelor can be considered in patients whowillundergo PCI treatmentafter fibrinolytic.

In PLATO study, patients who have acute coronary syndrome with or without ST-segment elevation, treatment with ticagrelor as compared with clopidogrel significantly reduced the rate of death from vascular causes, myocardial infarction, or stroke. However, patients who received fibrinolytic therapy within 24 hours before randomization were excluded. WhileinSET-FAST study, Ticagrelor provides more prompt and potent platelet inhibition compared with Clopidogrel in patients undergoing PCI within 24 hours of receiving fibrinolysis for STEMI. TREAT study was conducted to evaluate the safety of ticagrelor in STEMI patients receiving fibrinolytic therapy within 24 hours.TREAT study concluded, at 30 days observation, in patients younger than 75 years with STEMI, delayed administration of Ticagrelor after fibrinolytic therapy was noninferior to Clopidogrel for TIMI major bleeding.

Based on the result from PLATO study and preliminary TREAT study result on 30 days, the use of Ticagrelor within 24 hours after fibrinolytic therapy can be considered with comparable safety profile to Clopidogrel.

Published: September 2019

Von Willebrand disease (VWD), a blood coagulation disorder, is also known to cause angiodysplasia. Hitherto, no animal model has been found with angiodysplasia that can be studied in vivo. In addition, VWD patients tend to have a higher incidence of miscarriages for reasons unknown.
Thus, we aimed to examine the influence of von Willebrand factor (VWF) on the female reproductive tract histology and the expression and distribution of angiogenic factors in a porcine model for VWD types 1 and 3. The disease-causing tandem duplication within the VWF gene occurred naturally
in these pigs, making them a rare and valuable model. Reproductive organs of 6 animals (2 of each mutant genotype and 2 wildtype (WT) animals) were harvested. Genotype plus phenotype were confirmed. Several angiogenic factors were chosen for possible connections to VWF and analyzed alongside
VWF by immunohistochemistry and quantitative gene expression studies. VWD type 3 animals showed angiodysplasia in the uterus and shifting of integrin αVβ3 from the apical membrane of uterine epithelium to the cytoplasm accompanied by increased vascular endothelial
growth factor (VEGF) expression. Varying staining patterns for angiopoietin (Ang)-2 were observed among the genotypes. As compared with WT, the ovaries of the VWD type 3 animals showed decreased gene expression of ANG2 and increased gene expression of TIE (tyrosine kinase
with immunoglobulin and epidermal growth factor homology domains) 2, with some differences in the ANG/TIE-system among the mutant genotypes. In conclusion, severely reduced VWF seems to evoke angiodysplasia in the porcine uterus. Varying distribution and expression of angiogenic factors
suggest that this large animal model is promising for investigation of influence of VWF on angiogenesis in larger groups.

As these practices play a vital role in conserving socio-ecologically important species and protect threatened flora and fauna from extinction in different ecological zones. In northeast India, sacred groves are well connected with culture and society through religious beliefs of the population and their associated myths. Sacred groves cover a total of > 40,000 hectares of natural forest area in the five northeastern states of India. These forests house some of the most important and highly threatened species of plants. Wild relatives of present-day cultivated plants are found in these forests and hence act as the gene pool for these species. Social transformation and urbanization have a large impact on the structure and health of these forests and responsible for their destruction. Developmental projects like railways, roads, hydro-electric projects etc. have reportedly destroyed many groves in the past. Due to social transformation, the rate of activities like grazing, encroachment, cutting and collection of fuel wood, fruits and leaves has been increasing and posing a threat to the conservation of biodiversity and ecosystem function in the future. Creating awareness about the social and ecological benefits of maintaining sacred groves among local people, especially youth, can help in reviving these practices and conserving them as a natural heritage for future generations is the need of the hour.

Published: September 2019

Coal is an important non-renewable source of energy, which is being constantly used by mankind for various purposes. Coal mining activities affect the surrounding ecosystem by contaminating it with traces of toxic metals, which may accumulate and affect the diversity and abundance of biological communities. A number of microorganisms, such as, filamentous fungi, yeasts and bacteria are known to degrade coal by their enzymatic action and use it as the sole source of carbon. In addition, the indoor environments of coal mines possess bioaerosols, which may include living or dead allergens, pathogenic or non-pathogenic bacteria, fungi, viruses, mycotoxins, bacterial endotoxins, peptidoglycans, etc., that may cause skin, respiratory tract and other health problems. This article throws light on the impact of coal mining on the surrounding ecosystem, degradation of coal by the microbial inhabitants and their effects on the health of miners.

By nature coastal saline soils having several constraints in crop production in addition to that of heavy metals contamination deteriorate the soil productivity. To restore these contaminated soils, various remediation techniques in practices must be revamped. The present study was conducted to enhance the accumulation of heavy metals lead and cadmium in sunflower and improve the crop productivity using organic and inorganic soil amendments along with NPK fertilizers in completely randomized design. Soil samples were admitted to estimating soil physico chemical properties and DTPA extractable lead (Pb) and cadmium (Cd) and plant samples analyzed for DTPA extractable Pb and Cd concentrations under ICP-OES. The physico-chemical properties and DTPA extractable Pb and Cd concentrations were significantly influenced by amendments. Sunflower exhibited significant differences concerning accumulation of Pb and Cd against amendments tested along with higher biomass production. Higher shoot and root concentration of Pb(0.72,0.81 and 0.94,0.97 mg kg-1) and Cd (1.78, 2.32 and 0.35,0.32 mg kg-1)were recorded in the treatment RDF + EDTA, which was followed by RDF + Potassium humate and RDF + Zeolite application at 45 DAS and at harvest. Remediation efficiency of sunflower increased by application of RDF + EDTA through enhanced solubility of Pb and Cd in soil and thus increased Pb and Cd accumulation in root and shoot of sunflower. Whereas, the application of RDF+ FYM or press mud reduced the bioavailability of Pb and Cd in soil and thus restricted the accumulation of Pb and Cd by sunflower. Further, application of NPK fertilizers maintained the availability of nutrients and enhanced the yield of sunflower. The application of EDTA along with NPK fertilizer enhanced the bioaccumulation of lead and cadmium by sunflower without yield loss. Since, there is a possibility to cause leaching of HMs to ground water by EDTA. Hence, RDF plus Potassium humate or Zeolite can be recommended for lead and cadmium removal by sunflower in coastal saline soils with no loss in crop productivity.
Climate smart agricultural technologies in rice-wheat water stressed regions of Punjab, India- A review
Authors: Saini Jhanvi , Bhatt Rajan
Published: September 2019

Intensively cultivated rice-wheat cropping sequence of Punjab, India responsible for many sustainability issues viz. declining underground water, declining soil health, arising micro-nutrient deficiencies etc. Around 1.3 M ha-m additional withdrawal of water from the ground is being taken place annually in Punjab and mainly it is used for the rice crop which is not a traditional crop of the region. Puddling, seepage and percolation losses are the main sources of water loss from the rice based cropping systems in the Indo-Gangetic plains (IGPs) and many Resource Conservation Technologies (RCTs) have been recommended for water saving. The real water saving techniques are those which hinder the water from going into those sinks from where it cannot be reused (Evaporation, E) and diverted greater fraction of water of ET toward transpiration (T) which is desired as greater transpiration, greater the inflow of water and nutrients andwhich ultimately increase the grain yield with the lesser consumption of irrigation water as interval in between two irrigation increases, which further increase the water productivity. Among different RCTs, short duration crop varieties and delaying transplanting time are the real water saving techniques for the regions where water table is already declining down, however other RCTs may be suitable for the regions facing water logging problems as these cut down the drainage losses and these energy saving rather than water saving techniques.
Zinc and boron nutrition in pulses: A review
Authors: Raj Anju B. , Raj Sheeja K.
Published: September 2019

Zn plays major role in many physiological processes viz., chlorophyll formation, pollen formation, fertilization, protein synthesis, cell elongation, nodule formation etc. Hence, Zn nutrition favourably influences the growth, yield, physiological parameters and nodule formation in pulses. Similar to that of Zn, B also plays a major role in the functioning of reproductive tissues, structural integrity of plasma membrane, sugar transport, nodule development etc. Boron nutrition reduces the flower drop, increases the pod setting in pulses and also increased nodulation in pulses. The review elaborates the effect of Zn and B nutrition on the physiological, growth and yield parameters and yield of pulses and their effect on nodule formation and uptake of nutrients in pulses.

Mathematics Learning in Language Inclusive Classrooms: Supporting the Achievement of English Learners and Their English Proficient Peers
Authors: Saxe Geoffrey B. , Sussman Joshua
Published: September 2019

National and state assessments show that English language learners (ELs) in elementary and secondary grades score lower in mathematics compared with their matched English proficient peers (EPs). To provide information on strategies for enhancing learning opportunities for ELs in language inclusive classrooms, we analyze the efficacy of Learning Mathematics Through Representations (LMR), a curriculum unit on integers and fractions designed to support learning opportunities for ELs as well as EPs. LMR features the number line as a principal representational context and the use of embodied representations to support students as they explore mathematical ideas, construct arguments, and elaborate explanations. The study used a quasi-experimental design: Twenty-one elementary classrooms employing a highly regarded curriculum were included. Forty-four ELs were enrolled across 11 LMR classrooms, and 51 ELs were enrolled across 10 matched comparison classrooms. Multilevel analysis of longitudinal data on a specialized integers and fractions assessment, as well as a California state mathematics assessment, revealed that the ELs in LMR classrooms showed greater gains than comparison ELs and gained at similar rates to their EP peers in LMR classrooms. Further, contrasts between ELs in the LMR classrooms and EPs in the comparison classrooms revealed that LMR narrowed or eliminated the pretest achievement gap in mathematics. Both theory and empirical results support the value of LMR as a mathematics intervention benefitting both EL and EP students.
