Objective: To determine the electro physical agents (EPA) commonly used by physiotherapist in the management of non-specific low back pain in Karachi, Pakistan. Methodology: A cross sectional study was conducted on physiotherapist practicing in different clinical settings in Karachi Pakistan between January to March 2016. Written informed consent were taken from each study participants. Data were collected from 90 physiotherapists who were selected through non probability purposive sampling. Structured questionnaire was used to collect data. Data was entered and analyzed by using SPSS version 21. Results: It was found that out of 90 physiotherapists, 27(30.0%) male and 63(70.0%) female had responded. With mean (S. D) Age was 28.8(4.32188). The EPA used mostly in patients with non-specific low back pain as TENS 18(20.0%), Thermotherapy 17(18.9%, Ultrasound therapy 12(13.3%) and Interferential therapy 9(10.0%). In combination TENS, ultrasound and thermotherapy is about 8(8.9%) and interferential and thermotherapy is about 7(7.8 %). Conclusion: Physiotherapists give preference to some EPA such as TENS, Thermotherapy, Interferential therapy (I.F.C) and Ultrasound (U.S) to manage nonspecific low back pain. However, there is a need to highlights the use of EPA according to Evidence based practice.

Fruits are sweet fleshy products of a plants, that contain various nutrients and when consumed help the human in diverse ways. Some build up muscles, some burst immune system, some are anti-oxidant and amongst other functions. Because of the high commercial demand, naturally ripe fruits are scarce, thus; alternative (artificial) ways of making them ripe for consumption has become inevitable and uncontrollable. The aim of this study is to evaluate the effect of Calcium Carbide ripened fruit (Pawpaw) on the Haematological parameters of the Wistar rats. Mature unripe pawpaw’s were plucked off from the parent plant and were divide into two groups, one group was kept and allowed to rip at normal room temperature and the other group was induced with Calcium Carbide to ripe for 48 hours.10g of the CaC2 was placed in a bowl and 5ml of water was used to dissolved it in a closed metal bucket containing 1kg of the fruit [Pawpaw] rapped with black nylon and was allowed for two days [48 hours] for ripening. After ripening, sampled fruits were washed and juiced. 600g of both the naturally ripened and calcium carbide induced ripened fruits [Pawpaw] were peeled separately and blended in an electric blender with 350ml/1L of deionized water. The two sets of juice was filtered with a clean fine sieve and was poured into clean bottles labeled [CaC2 ripened and naturally ripened pawpaw juice]. A total of 21 adult Wister rats of both sexes weighing between 126.9g- 213.3g were used for this study. 9 Wistar rats were used for Sub Acute Test ( LD50). The rest 12 Wistar rats were divided into three groups (Control, Natural and CaC2). 5ml/kg of the naturally ripened and calcium carbide induced ripened fruits [Pawpaw] were administered orally to the rats based on the body weight. The rats were weighed weekly, then one rat was sacrificed in each group and blood samples were collected from the three groups for hematological analysis. The result showed reduction in mean Pack Cell Volume, Total White Blood Count, Hemoglobin, Red Blood Cells, Platelets, Neutrophil, Monocytes for both the Wistar rats fed with Naturally ripened and CaC2 ripened groups in comparison with the control group. There is evidence of increase in the mean Lymphocytes level for both the Wistar rats fed with Naturally ripened and CaC2 ripened groups in comparison with the control group, but the CaC2 treated group tend to be higher. Eosinophil levels is higher in the CaC2 treated group. In a nutshell, The consumption of fruits ripened with Calcium Carbide pose devastating effect on the bone marrow, deleterious effect on the circulating blood, heart and brain, that will evenly lead to myocardiac infarction, Eosinophilia, Anemia, thrombocythopenia, paralysis, stroke, seizure and mortality may eventually arise.

This study aims to determine the effect of economic growth, population, industrialization, energy consumption and fossil fuel consumption of CO2 emissions in G-20 countries. Panel data is used as a data analysis technique in this study. The variables used are based on the concept of the Environmental Kuznets Curve. The Kuznets hypothesis explains that an increase in economic growth reduces inequality and poverty in a certain period of time (or referred to as the turning point limit). This study focuses on the G-20 countries in the 2013-2018 period. Based on the regression results of the CO2 emission variables (CO2), gross domestic product (GDP), energy consumption (KE), population (JP), industrialization (IND) and fossil fuel consumption (BBF) it was found that all independent variables simultaneously (GDP, KE, JP, IND and BBF) have a significant effect on the dependent variable (CO2). Furthermore, partially significant variables that affect CO2 emissions are GDP, JP, IND and BBF, while the variables that have no significant effect on CO2 emissions are only KE. Support and commitment to policies both nationally and regionally are needed to reduce environmental degradation through inclusive economic growth in G-20 countries.

Background: Every year, more than half a million people in the world suffer from acute cerebrovascular events, including ischemic stroke, intracerebral and subarachnoid hemorrhage, giving a mortality of nearly 20%. Acute strokes, especially subarachnoid hemorrhage is frequently accompanied by a variety of electrocardiographic (ECG) abnormalities. Objective: To find out the cardiac function assessment by echocardiography in ischemic stroke/non hemorrhagic cerebral infarction. Material and Methods: An observational study was conducted in Department of Medicine and Cardiology, Sher-E-Bangla Medical College Hospital, Bangladesh from July to December-2019. 51 patients of ischemic stroke were taken and 2D transthoracic echocardiography was done to find potential cardioembolic abnormalities. Results: 74.5% of patients had echocardiographic abnormalities and 41.1% had potential cardioembolic abnormalities, out of which most common were ventricular wall hypokinesia, calcific aortic valve, rheumatic heart disease and dilated cardiomyopathy. The prevalence was almost similar in different age groups and both the sexes. Conclusion: Prevalence of potential cardioembolic abnormalities is high (41.1%) in ischemic stroke patients and 2D echocardiography is therefore recommended in the management and secondary prevention of cardioembolicstroke, which has a higher mortality and more chances of recurrence than atherothrombotic type of ischemicstroke.

Some infectious oral diseases are treated by medicinal plants in tropical areas, because they are abundant and cheap. The present work aimed to evaluate the antiseptic activity of the aqueous extract of Alchornea cordifolia leaves against three oral bacteria recognised as opportunistic pathogens, namely Streptococcus mitis, Staphylococcus epidermidis, and Micrococcus luteus. Fresh leaves of A. cordifolia were harvested, dried and pulverised. The extraction was performed by decocting in distilled water. The phytochemical screening was performed on the extract based on principles of colour change, and precipitation. Biological studies consisted in the in vitro antiseptic evaluation of the aqueous extract using the agar disc diffusion method, in comparison with a reference antiseptic mouthwash containing chlorhexidine. The extract had a 11.96% yield. The phytochemical screening revealed the presence of alkaloids, phenols, flavonoids, terpenes, tannins, glycosides, coumarins and saponins. The evaluation of the antiseptic activity revealed that the extract is active against S. mitis and S. epidermidis, and inactive against M. luteus. The diameters of inhibition zones were 16.9±1.1mm and 11.2±0.7mm at the concentration of 40mg/ml, and 7.7±0.3mm and 8.5±0.5mm at the concentration of 20mg/ml against S. mitis and S. epidermidis, respectively. Chlorhexidine did not inhibit S. mitis and showed diameters of inhibition of 13.0±1.0mm and 15.1±1.0mm against S. epidermidis and M. luteus, respectively. The minimal inhibitory concentration of the extract against the 2 sensitive bacteria was 20mg/ml.

In the present era of technology it has been simpler to deal with the disaster both natural and man made. Disaster Management activities rely upon substantial volumes of precise, applicable, on-time geo information that different organization systematically make and maintain. Information Technology is changing each part of human life. Disaster management desires forceful enhancements in its sources to decrease injury and save the lifetime of individuals. The advanced methods of information technology such as web, remote sensing, satellite communication, GIS, etc. can facilitate in coming up with and implementation of disaster management. Web provides a useful platform for disaster mitigation communications. On GIS is basic as effective preparedness, communication and training tool for disaster management on the other hand Remote Sensing as a tool can very effectively contribute towards identification of hazards areas. Communication satellite have become vital for providing emergency communication and timely help into natural disaster monitoring and mitigation mechanisms is critical for hazards reduction. There should be more emphasis on development of new technologies in disaster mitigation. The disaster preparedness and awareness is the only effective method of mitigating the impact of future disaster. In this paper an attempt has been made to highlight the role of information technology in management of natural disaster in Nepal.

The mode of locomotion of humans and primates leads to changes in their skeleton. Objective: Establish a link between the morphology of the tibia and the locomotive function from a comparative anatomical study between the tibias of bipeds, Homo Sapiens (HS) and Pan troglodytes verus (PTV), and of quadrupeds, Canis lupus familiaris (CLF) and Sus scrofadomesticus (SSD). Materials and methods: It concerned an analytical and comparative study by direct observation involving a sample of 52 tibias. We proceeded by direct observation, to a synthetic analysis of the morphological characteristics of the tibia that we compared in bipeds and in quadrupeds. Results: The tibial diaphyses of HS and PTV presented the same morphological conformation with an italic S aspect in HS and a varus aspect in PTV. With CLF and SSD, they are straighter and the different faces are distributed differently. The proximal epiphyses are voluminous and massive in both classes. In quadrupeds, they present upper tibial articular surfaces which are deformed backwards and a voluminous anterior tibial tuberosity. The distal epiphyses in quadrupeds are convex with more pronounced creases. Conclusion: This comparative study allowed us to demonstrate that the locomotive function has a significant impact on the morphology of the tibia.

Background: A common cause of mortality is traumatic brain injury (TBI). One of the deadliest complications is cerebral bleeding. Unanimously, CT scans are considered as gold-standard diagnostic tools for traumatic brain damage. In-patient assessment is aided by the patient's general condition score (GCS). Patients with a high GCS are often overlooked, yet it is possible that they may have major difficulties in the future. However, it is debatable whether or not a CT scan should be performed in individuals with GCS between 13 and 15 or not. Objective: It is our goal to examine individuals who have suffered head trauma and have a high GCS 10-15 on a CT scan who may have been overlooked but are now experiencing symptoms. We discovered the prevalence of ICH in 70 individuals with GCS ranging from 10-15. Methods: The computed tomography scans of 70 individuals with head trauma were performed. All patients underwent a non-contrast computed brain CT scan of 5mm axial images and slice thicknesses from the foramen magnum up to the vertex from which the findings were obtained. The patient's name, age, gender, and GCS score were all entered into a Performa. Results: The results showed that 32 patients (45.71 percent) experienced cerebral bleeding out of 70 individuals. Conclusion: Patients with RTA are at greater risk of developing ICH, and this risk is greater in men than in women.

The Balance of Payments in Nigeria was studied using annual data from 1981 to 2019 in this article. The paper's major goal was to examine the long-term factors that influence Nigeria's Balance of Payments. The Autoregressive Distributed Lag Model (ARDL) was used in the investigation. Long-term results from the ARDL regression showed that the exchange rate coefficient was negative, whereas short-term results showed a positive value. Also, the coefficients of FDI, GDP growth, interest rates, and crude oil prices were positive and significant. There is a strong case can be made for governmental intervention to improve economic productivity, as evidenced by this study. To help the economy thrive, capital investments and expenditures should be made. The government should make incentives to prospective foreign investors in order to attract FDI inflows into the country. Government should also enhance safety and security and build a sense of belonging in the Niger Delta in order to promote peace and ease of doing business in the petroleum industry there.

People in the rural regions of the developing countries where electricity supply is not available are facing the problems of preserving their food through refrigeration. They need affordable and efficient method of food preservation. Therefore, a solar operated refrigerator was designed, constructed and evaluated. The system consists of three major parts, namely: the mild steel box (0.4 𝑚 × 0.4 𝑚 × 0.5 𝑚), the clay shell and the wooden box (0.5 𝑚 × 0.5 𝑚 × 0.6 𝑚). The mild steel box is enclosed in a clay shell, which is in turn enclosed in a wooden box with four open ducts. The work evaluated convective heat transfer through the ducts and the machine was tested on no load and also by using it to cool 40 kg of water for seven consecutive days over a period of eight hours per day. The results from its performance tests indicated that the system has a cooling process coefficient of performance (COP) of 2.48 and overall coefficient of performance (COP) of 1.64.

The physicochemical properties of the extracted oil from almond seed were investigated. Physical properties such as cloud point, pour point, fire point, smoke point, specific gravity, refractive index, and viscosity; and the chemical properties such as acid value, free fatty acid, saponification value, iodine value, ester value, and peroxide value were investigated for both raw almond oil and transesterified almond oil. The various properties were investigated using ASTM standard methods and calculations. Results obtained for physical properties: cloud point, pour point, fire point, smoke point, specific gravity, refractive index, and kinematic viscosity were 〖-3〗^o C, 〖-9〗^o C, 〖220〗^o C, 〖130〗^o C, 0.928, 1.462, 21.84 〖mm〗^2/sec respectively for the transesterified almond oil. Result obtained for the chemical properties of the transesterified almond oil: acid value, free fatty acid, saponification value, iodine value 〖mgI〗_2/g, and ester value, values were determined to be: 2.05, 1.03, 79.71, 34.33, and 77.66. It was concluded that transesterified Almond oil have a great potential for use as fuel alternative and substitute for internal combustion engine with its high purity, low corrosion ability and ease of ignition.

In this research, alternative Raman amplifier configuration were used in a wavelength division multiplexing (WDM)-passive optcal network (PON) system to investigate their effects on channel capacity and signal quality. Because of its scalability, energy efficiency, high capacity, low cost, and flexibility of data transfer ability, various Raman configurations are applied in different position to measure the output power. We used various techniques to evaluate the system performance such as varying the length of an optical fiber from 10 to 100 kms, number of users by increasing 8 to 16 channels. Various channel spacings are utilized in an 8 and 16 channels WDM system to calculate the system's bit error rate (BER) and signal-to-noise ratio (SNR). Another key concern is the high data rate and to achieve the maximum transmission speed. We get the maximum data rate of 128 Gb/s by 8 channels and 192 Gb/s by 16 channels. The maximum BER was 10-9and noise level was -6.35 dBm associated with the distance which was 70 kilometers long fiber channel. Finally, maximum data rate and its related eye diagrams was evaluated.

The massive demand for global transformations describes the necessity of high-speed communication in the twenty-first century. Almost every facet of online networks is changing, including international relations, politics, trade, and security. However, cyber security has become a major issue all around the world. Bangladesh has recently taken the required steps to address the problem as swiftly as feasible. In order to prevent and combat cyber threats, the government of Bangladesh plans to establish a specialized computer incident response team (CIRT) for banks and financial institutions, which will serve as the national response team responsible for receiving, reviewing, and responding to computer security incidents and activities in Bangladesh. Implementing strong and multilayer authentication to better management of the data, as well as discovering and mapping out security issues, some major initiatives are required to implement cyber security. Engineers should obtain hands-on training in decoding corrupted data files during any cyber-attack in order to recover data from any lost data. In this review, cyber security challenges in smart cities and smart governance have been examined, with an emphasis on e-commerce, machine learning, industry automation, IoT, and other security elements. The main cyber security concerns are discussed in order to better comprehend almost every necessity of long-term cyber security situations. Moreover, smart industry control and its security infrastructure, problems for implementation in Bangladesh and recent security issues have been highlighted.

Oxidative stress is often associated with diabetes mellitus (DM). It has been reported to cause infertility in males. Diagnosed at an advanced phase, DM-associated complications may not be reversed by standard therapy alone. This study therefore investigated whether zinc given alongside insulin may reverse or ameliorate oxidative stress induced by DM. Five normal rats was assigned into the normal control group. Twenty diabetic rats were randomly assigned into four groups of five rats each. The first group had no treatment throughout the experiment. The second group were administered insulin two times daily at one and four units in the morning and evening. The third group had oral zinc (10mg/kg). The fourth group had a combination of insulin and zinc at doses as above. Treatments in all cases commenced after two weeks of DM induction and lasted ten days. Testes were harvested and assayed for parameters. DM decreased SOD, GPx, GSH and increased MDA. While insulin or zinc increased SOD, GPx, GSH and decreased MDA, insulin and zinc in combination had better results.
