The purpose of the present study is to highlight the valuable contribution of Mr. Zafar Iqbal for winning the last gold medal for India in the 1980 Moscow Olympics. He led the Indian team as a captain in various international events, prominent among them were Asian Games in 1982, Champions trophy, 1983, and 1984 Los Angeles Olympics. He was honoured by carrying the Indian flag at the youth festival held in Moscow, and later at the opening ceremony of the Los Angeles Olympics. He received the prestigious Arjuna Award in 1983, the highest award given to a sports personality in India. Mr. Zafar Iqbal was recruited as subjects of the study. To find out the score of Arjuna Awardee Zafar Iqbal on Neuroticism, Extraversion, Openness, Agreeableness and Conscientiousness. The NEO five-factor inventory scale was developed by Costa and McCrae (1991). Results have revealed that Mr. Zafar Iqbal scored average on neuroticism, extraversion and openness dimensions, and low on agreeableness and high on conscientiousness
California bearing ratio tests of enzyme-treated sedimentary residual soil show no improvement
Environmental concerns have significantly influenced the construction industry regarding the identification and use of environmentally sustainable construction materials. In this context, enzymes (organic materials) have been introduced recently for ground improvement projects such as pavements and embankments. The present experimental study was carried out in order to evaluate the compressive strength of a sedimentary residual soil treated with three different types of enzymes, as assessed through a California bearing ratio (CBR) test. Controlled untreated and treated soil samples containing four dosages (the recommended dose and two, five and 10 times the recommended dose) were prepared, sealed and cured for four months. Following the curing period, samples were soaked in water for four days before the CBR tests were administered. These tests showed no improvement in the soil is compressive strength; in other words, samples prepared even at higher dosages did not exhibit any improvement. Nuclear magnetic resonance (NMR) spectroscopy tests were carried out on three enzymes in order to study the functional groups present in them. Furthermore, X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) tests were executed for untreated and treated soil samples to determine if any chemical reaction took place between the soil and the enzymes. Neither of the tests (XRD nor FESEM) revealed any change. In fact, the XRD patterns and FESEM images for untreated and treated soil samples were indistinguishable
Trend of Mortality by Water Related Intestinal infectious Diseases: A Study of National Capital Territory of Delhi, (2001 to 2011)
National Capital Territory (NCT) of Delhi is experiencing rapid urbanization for the last few decades. The area is lagging behind in water and waste management infrastructure. This is due to the fact that Delhi is recording high growth rate of population mostly through in-migration over the year which is taxing much upon the existing water resources and the provisions made for water supply. Consequently demand is higher than supply of the safe drinking water. The consumption of unsafe drinking water is therefore increasing and is causing serious health problems among the fellow residents of NCT of Delhi. These health problems are basically related to the digestive as well as excretory systems of the human body. These disorders are promoting mortality particularly among those segments of population which do not have access to potable drinking water. This paper is therefore a modest attempt towards examining the population growth rate and the scenarios of demand and supply for potable water as well as the overall water related intestinal infections and related mortality at present and their future occurrence. This requires synergy between the different sectors of the state to overcome the problem. of intestinal infection diseases in the region
Effects of nano-carbon reinforcement on the swelling and shrinkage behaviour of soil
In this study, the performance of two types of nanocarbons (NCs), namely carbon nanotubes (CNTs) and carbon nanofibers (CNFs), on the three-dimensional shrinkage and swelling properties of three clayey soils were investigated. The specimens of soil mixed with clay with bentonite contents of 0, 10 and 20% by weight of dry soil. NC contents of 0.05, 0.075, 0.10 and 0.20% were chosen to investigate the influence of different NC types, CNTs and CNFs. All soil specimens were compacted under maximum dry unit weight and optimum water content conditions by using standard compaction tests. The physical and mechanical characteristics of the reinforced samples were then determined. These included the desiccation cracking area, used to determine the crack intensity factor (CIF), as well as the shrinkage and swelling. The CIF for the soil specimens without NCs were higher than the soil specimens with NC additives. These results show that NCs decrease the development of desiccation cracks on the surface of compacted samples. The shrinkage and swelling tests showed that the rate of volume changing of the compacted soil specimens reduced with the increasing of NCs

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries
Abstract
Background
Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres.
Methods
This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries.
Results
In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia.
Conclusion
This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries
A COMPARATIVE STUDY OF STATE ANXIETY TEST BETWEEN UNIVERSITY AND NATIONAL LEVEL HOCKEY PLAYERS OF UTTAR PRADESH
Effect of Three Bioenzymes on Compaction, Consistency Limits, and Strength Characteristics of a Sedimentary Residual Soil
Bioenzymes are organic degradable materials, currently introduced as soil improvement additives. In this experimental study, three types of bioenzymes from three different countries were used to improve Universiti Kebangsaan Malaysia (UKM) soil. UKM soil has properties quite similar to soils recommended as suitable by bioenzyme suppliers. The effect of the three bioenzymes on Atterberg limits, compaction characteristics, and unconfined compressive strength was studied. Controlled untreated and treated samples for two dosages at curing times up to three months were prepared and tested after completion of the curing period. Some results showed little improvement in compaction characteristics, and unconfined compressive strength, but no notable improvement was noticed in Atterberg limits. X-ray diffraction (XRD), X-ray fluorescence (XRF), and field emission scanning electron microscopy (FESEM) tests were conducted for untreated and treated soil samples after two months of curing. XRD and XRF did not show any change in mineralogy and chemical composition between controlled untreated samples and samples treated with the three bioenzymes. However, the FESEM images revealed a denser packing of particles for soil samples treated with two of the bioenzymes
Effect of Mixing towards the Production of Carbonaceous Kenaf Fiber via Hydrothermal Carbonization Process
Hydrothermal carbonization process (HTC) is a relatively simple method to convert biomass to carbonaceous material that involves reaction in a closed system. HTC is convenient, fast and environmentally friendly way to convert biomass into higher value of carbonaceous material. A comparison on the carbon percentage produced from HTC using Kenaf fiber is performed and the optimum HTC operating condition of Kenaf fiber is aimed. The heating process is carried out using two different conditions, with and without stirring at different time period which is 2 hours, 4 hours, 6 hours, 8 hours and 10 hours at constant temperature of 225 °C. Vario Micro CHNS Analyzer used to determine the element values in the sample shows that for sample without stirring, sample heated for 2 hour produces lowest carbon percentage which is 52.51% and sample heated for 10 hour produces the highest carbon percentage which is 60.20% similar trend was obtained for the stirring sample heated for 2 hour produces 48.43% and sample heated for 10 hour produces 56.73%. The percentage of carbon increase as the longer time period of heating. Based on the results, samples without stirring obtain the higher percentages of carbon content compared to the samples with stirring at 10 hour operating time
Synthesis of Nanocellulose from Rubberwood Fibers Via Ultrasonication Combined with Enzymatic and Chemical Pretreatments
This paper presents synthesis of nanocellulose from rubber wood (Hevea brasiliensis) fibers via ultrasonication combined with enzymatic and chemical pretreatments. Cellulose nanofibers were separated from rubber wood fibers in three distinct stages. Initially, rubber wood fibers were subjected to a series of enzymatic and chemical pre-treatments to eliminate lignin and hemicellulose. The obtained chemical-purified cellulose fibers were then mechanically separated into nanofibers using ultrasonication. The diameter distributions of the resulting nanofibers were dependent on the output power of ultrasonic treatment. The extent of dispersion improved significantly with increasing output power of ultrasonic treatment. Microscopy study showed that the diameters of the nanofibers isolated ranged from 8.7 to 20 μm. The effectiveness of laccase and xylanase enzymes was also studied. The results obtained from FTIR and thermo gravimetric analyses indicated that there were consistencies between the studied enzymes to the thermal stability or chemical structure. FTIR spectroscopy confirmed that the prominent peaks indicating that most of the lignin and hemicellulose were removed during the step-wise chemical treatment were present in the spectrum. FTIR spectroscopy suggested that the spectrum of cellulose nanofibers obtained under different ultrasonic output powers and chemical-purified cellulose fibers were similar, signifying that the molecular structure of cellulose were unaffected by the ultrasonic treatment. TGA results revealed that the thermal properties of cellulose nanofibers were enhanced and the thermal degradation temperature increased to proximately 310 °C as compared to 240 °C of the untreated rubber wood fibers. Results from this work may be potentially applied in various fields such as bio-nanocomposites, filtration media packaging, tissue engineering scaffolds, and so on
