    The main purpose of our study is to estimate the demand equation. By using this equation, we have to forecast the future demand. To forecast demand, we have collected actual data on demand of Dalda, price of Dalda, price of Hoor and total sales from Jan 2013 – Dec 2014. By using the Multiple Regressions, we have formulated the demand equation from actual data, and then we have forecasted the values by using exponential smoothing technique for all independent variables. Forecasted demand for the Jan of 2015 is 2072.2921, Quantity demanded will increase by 272.2921 (15 percent) for Jan 2015 as compared to the Jan of 2013. We find that price elasticity is -0.825279 it means that demand of Dalda lie in inelastic portion, it means that if price increase or decrease, there is less impact on the quantity demanded. Cross price elasticity of sultan is positive, its value is 0.4964 it shows that it is substitute commodity. Cross price elasticity of Hoor should be positive, but according to our result its value is –2.718552, which means that in this specific area people are using Hoor as a complementary product .Cross price elasticity of total sales is 1.7299.

    The Sole purpose of the study is to carve out the performance and structure of the small and medium scale manufacturing sector of Pakistan in terms of employment and productivity. The present study has incorporated the transcendental logarithmic cost function to apply on secondary, cross section data of the 3-digit forty nine SMEs of Pakistan. This functional form allows for and assists in exploring the true production structure of the firms. It has been revealed that structure of SMEs in Pakistan is based on Non-homothetic, Non- homogeneous, Variable returns to scale and Non-unitary elasticises. It has further been found that SMEs are overwhelmingly efficient as the pro- SMEs advocate them, in terms of employment generation and productivity, as capital and labour are found to be substitutes, which means employment generation is possible without the expansion in capital in a densely populated country like Pakistan. The conclusion suggests that although public policy should be targeted to provide parallel support to capital and labour yet distinguished favour should be given to labour to generate employment in SMEs of Pakistan.

    Onychomycosis is a common fungal infection of nails. It is usually further divided into four types which are Distal and lateral subungual onychomycosis (DLSO), white superficial onychomycosis (WSO), proximal subungual onychomycosis (PSO) and candidal onychomycosis (CO). The main causative agents of onychomycosis are three fungal forms: dermatophytes, yeasts, and non-dermatophytes molds. In current study, occurrence frequency of various types of onychomycosis was observed in a selected region of Pakistan. Collected data were statistically analyzed at 0.001% significance level by using single factor ANOVA for comparative examination on the basis of gender, age and onychomycosis types. Results indicated that males suffer more than females, adults are more prone to get onychomycosis attack and DLSO is frequently occurring than other forms. The root causes of this epidemiological trend were lack of personal hygiene and health care awareness among masses and knowledge about symptoms and effects of onychomycosis meanwhile poverty was also found as a leading indirect reason for the spread of this nail disorder. Future researchers should find out cost effect local alternatives for treatment and control of onychomycosis along with some general public awareness program

    <p>Abstract</p> <p>Objective</p> <p>The aim of this study was to explore inequities in knowledge, attitudes and practices regarding tuberculosis (TB) among the urban and rural populations.</p> <p>Design</p> <p>A cross-sectional study was conducted in two districts of Pakistan's Punjab province. The 1080 subjects aged 20 years and above, including 432 urban and 648 rural respondents, were randomly selected using multistage cluster sampling and interviewed after taking verbal informed consent. Logistic regression was used to calculate the crude odds ratio (OR) with 95% confidence interval (CI) for the urban area. The differences in knowledge, attitudes, practices and information sources between the urban and rural respondents were highlighted using Pearson chi-square test and Fisher's exact test.</p> <p>Results</p> <p>The study revealed poor knowledge regarding TB. The deficit was greater in the rural areas in all aspects. The knowledge regarding symptoms (OR 2.03, 95% CI 1.59-2.61), transmission (OR 1.93, 95% CI 1.44-2.59), prevention (OR 2.24, 95% CI 1.70-2.96), duration of standard treatment (OR 1.88, 95% 1.41-2.49) and DOTS (OR 1.84, 95% CI 1.43-2.38) was significantly higher in the urban areas (all P < 0.001). Although a majority of the subjects (urban 83.8%, rural 81.2%) were aware of the correct treatment for TB, less than half (urban 48.1%, rural 49.2%) were aware of the availability of the diagnostic facility and treatment free of cost. The practice of seeking treatment at a health facility (P = 0.030; OR 2.01, 95% CI 1.06-3.82), as soon as they realized that they had TB symptoms (P < 0.001; OR 1.72, 95% CI 1.26-2.35), was significantly higher in the urban areas. People in the urban areas were more likely to feel ashamed and embarrassed being a TB patient (P < 0.001; OR 2.03, 95% CI 1.50-2.76); however, they seem to be supportive in case their family member suffered from TB (P = 0.005; OR 1.53, 95% CI 1.13-2.06). Nearly half of the respondents, irrespective of the area of residence, believed that the community rejects the TB patient (urban 49.8%, rural 46.4%). Television (urban 80.1%, rural 68.1%) and health workers (urban 30.6%, rural 41.4%) were the main sources for people to acquire the TB related information.</p> <p>Conclusion</p> <p>Respondents' knowledge regarding TB was deficient in all aspects, particularly in the rural areas. Intended health seeking behavior was better in the urban areas. Television and health workers were the main sources for TB related information in both the urban as well as the rural areas. Therefore, the area of residence should be considered in tailoring communication strategies and designing future interventions for TB prevention and control.</p

    Medicinal plants are composed of a rich pool of biomolecules and have been increasingly recognized for their antimicrobial properties; however, increasing concerns have been put on the bioavailability features. Thus, this study is aimed at exploring the synthesis and characterization of silver nanoparticles synthesized by Chenopodium album L. leaf extract and assessing the antifungal activity against Aspergillus terreus Thom. Plant extract was prepared in methanol to synthetize silver nanoparticles, which were then characterized by Scanning Electron Microscopy (SEM), UV-Visible spectroscopy, and particle size analysis. UV-Visible analysis indicated maximum absorption at 378 nm, and an average particle size was observed as 25.6 nm. Oval to hexagonal shape was observed by SEM. Antifungal activity of silver nanoparticles (1, 1.5, 2, 2.5, 3, and 3.5%) was addressed against A. terreus biomass. At 3.5%, silver nanoparticles revealed to be highly effective, leading to 92% retardation in fungus growth. In next phase, various organic fractions, viz., chloroform, n-butanol, n-hexane, and ethyl acetate, were obtained from plant methanol extract, and the corresponding silver nanoparticles were prepared. These fractions were also assessed for antifungal activity, and n-hexane fraction led to 64% inhibition in A. terreus biomass. Following gas chromatography-mass spectrometry (GC-MS), 18 compounds were identified, namely, 1,3-cyclopentadiene-5-(1 methylethylidene and o-xylene), ethyl benzene, octadecane, nonane, decane, 2-methylheptane, n-hexadecane, 2-methylheptane, and eicosane, along with carbonyl compounds (4,4-dimethyl-3-hexanone) and phenols, like stearic acid, propionic acid hydrazide, and 2,4-di-T-butylphenol. These findings proved that C. album silver nanoparticles are highly effective against A. terreus.N.C.-M. acknowledges the Portuguese Foundation for Science and Technology under the Horizon 2020 Program (PTDC/PSI-GER/28076/2017)

    Get PDF
    INTRODUCTION: In recent years, several non-specialist mediated interventions have been developed and tested to address problematic symptoms associated with autism. These can be implemented with a fraction of cost required for specialist delivered interventions. This review represents a robust evidence of clinical effectiveness of these interventions in improving the social, motor and communication deficits among children with autism. METHODS: An electronic search was conducted in eight academic databases from their inception to 31st December 2018. A total of 31 randomized controlled trials were published post-2010 while only 2 were published prior to it. Outcomes pertaining to communication, social skills and caregiver-child relationship were meta-analyzed when reported in \u3e 2 studies. RESULTS: A significant improvement was noted in child distress (SMD = 0.55), communication (SMD = 0.23), expressive language (SMD = 0.47), joint engagement (SMD = 0.63), motor skills (SMD = 0.25), parental distress (SMD = 0.33) parental self-efficacy (SMD = 0.42) parent-child relationship (SMD = 0.67) repetitive behaviors (SMD = 0.33), self-regulation (SMD = 0.54), social skills (SMD = 0.53) symptom severity (SMD = 0.44) and visual reception (SMD = 0.29). CONCLUSION: Non-specialist mediated interventions for autism spectrum disorder demonstrate effectiveness across a range of outcomes for children with autism and their caregivers

    Despite the fact that fertilizers have been used for millennia for sustainable crop production, this high and considerable dependence on fertilizers heightens environmental concerns with the indirect human exposure due to accumulation of toxins in food chain via soil contamination. The purpose of this study is to evaluate the application of fertilizers to the soil and their effect on the accumulation of copper and nickel in spinach (Spinacia oleracea), garlic (Allium sativum), wheat (Triticum aestivum), maize (Zea mays), and barley (Hordeum vulgare); as well as potential health concerns associated with consuming vegetables cultivated on this contaminated land. Samples of available soil, food crops, and human blood were collected from three different Tehsils: Bhalwal, Sahiwal, and Silanwali and were regarded as site 1, site 2 and site 3 respectively. Urea, farmyard manure, and potassium chloride were delivered to Site 1; urea phosphate, manure, and ammonium sulphate were delivered to Site 2; and superphosphate, ammonium phosphate, and nitrate phosphate were delivered to Site 3. Data was subjected to statistical analysis for computing out ANOVA and correlation. Analysis revealed that minimum copper concentration was found in the soil of T. aestivum grown at Site-1 while the inhabitants of Site 3 had the highest concentration of Cu in their blood. The highest level of HIR was found in the human beings that ate the S. oleracea grown at Site 3. It is strongly advised that fertilizers be used sparingly, as their excessive use can cause human health risks
