The majority of the Namal’s students belong to rural areas, and 97% of them secured scholarship either due to meritorious educational background or being unable to afford education (i.e., needbased scholarship). To ensure quality, Namal has kept a student-faculty ratio of 10:1. It is one of the pioneering institutes focusing on Agribusiness and Agri-tech education in Pakistan. It has a beautiful campus comprising of 1000 Acres land located in the Salt Range in an area consisting of hills and crags overlooking Namal Lake in the Mianwali District. To foster its sustainability efforts, Namal has planted an olive garden on an area of 4 acres. Recently, two new blocks have been constructed using...

Experiments were conducted during summer season of 2009 to look for effective and economically viable weed control method(s) in dry seeded rice. Four mulching materials of natural origin as sorghum, sunflower and wheat residues each soil incorporated at 8 t ha-1 and black polyethylene sheet strips as artificial origins were used. A weedy check and manual weeding were included for comparison. Label doses of post emergence herbicides, bis-pyribac sodium and penoxsulam, at 30 and 15 g a.i. ha-1 were also used. Manual weeding accounted for maximum (99%) inhibition in weed density and dry weight. Bispyribac sodium suppressed weed count and dry weight by ≈ 80%. Among non-chemical weed management strategies, sorghum residues scored over 50% reduction in weed density and dry weight. Plastic sheet strips were least effective against weeds. Manual weeding scored highest paddy yield of 4.17 t ha-1. Bispyribac sodium with 3.51 t ha-1 paddy yield appeared superior to penoxsulam. Sorghum, sunflower and wheat residues resulted in statistically similar paddy yields of 2.85, 2.80 and 2.58 t ha-1 , respectively. Bispyribac sodium exhibited maximum marginal rate of return of 23076%. Chemical control proved to be a viable strategy with higher economic returns.

Every day hundreds of automobile drivers spend lots of the time to find wherein to park. The end result of this example is theft in urban areas, growing traffic congestion and frustration of drivers. In order to solve this problem, a study has been carried out to use a smart parking application that utilises machine learning algorithms to help in providing automated car routes to their parking spots in parking areas at

In this paper, we estimated the ISEW for Pakistan and highlight those factors that affecting wellbeing negatively. Findings of the study reveal that, in long run, there is a disconnect between economic growth and human wellbeing. In case of Pakistan, key contributing factors that affects human wellbeing negatively include income inequality, deteriorating international investment position, rapid depletion of natural resources and negative environment effects of economic activities. It is recommended to develop inclusive, sustainable and people centric policies with more focus on human wellbeing instead of absolute economic growth.

Osteoarthritis is more prevalent in women. It caused by ageing, pathophysiological situations, ecological factors, hormonal, environmental, and genetic factors. Epigenetic is “in addition to genetics. Epigenetic mechanisms such as histone modifications, DNA methylation and non-coding RNA are important parameters in controlling quantity, location and timing of gene expression. The treatment available is only painkillers and anti-inflammatory. In this review, we discuss how these epigenetic mechanisms are involved in the pathogenesis of osteoarthritis and find possible therapeutic targets in the prevention of disease. Epigenetic mechanisms regulate gene expression either by disturbing gene transcription or by acting post-transcription. In mammals DNA methylation is occur at Cp G dinucleotides at the outside of CpG. However cytosine is specifically methylated to 5-methylcytosi...

Two tests i.e. Phillips and Ouliaris'ˆu P and Choi Durbin-Hausman statistic are the leading performers and are recommended for any sample size. The remaining eight tests are recommended for only large sample sizes of 200 or greater. The use of all these ten tests is not recommended when presence of both intercept and linear time trend is assumed in cointegrating equation unless the sample size is very large i.e. greater than 200.

Simulated critical values, instead of asymptotic critical values, have been used to keep the size of all tests around nominal size of 5%. Our findings suggest HD and HL tests as better performing tests as compared to other panel stationarity tests.

Total sample size was 101995. It is descriptive cross-sectional study which includes patients of different ages, sex and motor-vehicles accidents having different injury sites. BACKGROUND & OBJECTIVE: Road traffic accidents are the ninth leading cause of death worldwide, contributing significantly to global disease burden. Emergency Medical services(EMS) play a role in minimizing the morbidity and mortality. Our objective was to determine the characteristics of injury pattern and causes encountered in Road Traffic crashes (RTCs) managed by 1122 in Faisalabad Pakistan and to access the outcome of these accidents.

Study Design: Descriptive cross-sectional study. Place and Duration of Study: Study was conducted for three months at Armed Forces institute of Cardiology and National institute of heart diseases. Methodology: A semi-structured knowledge questionnaire was developed and filled by all nursing officers, nursing technicians and healthcare workers, included in the study, for assessment of knowledge regarding the disposal and hazards associated with biomedical waste. Results: It was found that 140/229 (61.1%) study participants had a good knowledge and awareness about hospital waste disposal and handling, whereas 70/229 (30.5%) participants had a moderate level of knowledge, and 19/229 (8.6%) had a poor level of knowledge. Conclusion: Our results reflected that majority of the health care workers of our institute are well aware of the hospital waste mana...

Panel data methodology along with First Difference Generalized Method of Moments (GMM) technique is used for estimation. The result shows positively significant investment cash flow sensitivity. The ICFS also increases monotonically with the level of financial constraints. Additionally, result demonstrates that ICFS for constrained group is significantly higher relative to unconstrained group. The study has imperative implications for policy design and implementation.

The data sample includes monthly observations from the years 1780 to 2020. Our static analysis shows precious metals, soft foods, grains and, base metals as a net transmitter of spillover. The time-varying analysis shows that connectedness increases during economic crises, political uncertainty, and commodity-driven supply shocks. Our results have important implications for regulators, portfolio managers, and policymakers.

To study the dynamic spillovers, we use a TVP-VAR approach. Our results show a significant increase in the dynamic connectedness between media coverage, emerging market bonds, and US bonds, as well as between the respective volatilities, especially during the early phases of the Covid-19 pandemic, with the highest values observed in March 2020. The emerging market bonds appear to be net transmitters to the system and lead the system; whereas, the US bond market is the net receiver. These results show that, during the pandemic, the US bond market is less vulnerable and more resilient to changes in market sentiment vis-a-vis the fixed-income markets of the developing countries.
