Iron deficiency Anemia is a global public health concern. We aim to assess a national program for Weekly Iron and Folic-acid Supplementation (WIFS) to address this concern among adolescents in India. A longitudinal interventional community-based study was conducted with 1100 school-going adolescents. A questionnaire regarding socio-demographic profile, anthropometric details, and clinical examination, hemoglobin levels, and WIFS supplementation were conducted to collect information at 0, 3, 6, 9, and 12 months. The mean age of adolescents was 13.7 years. Anemia among students reduced from 95.8% to 75% post-intervention. The mean level of hemoglobin was 9.69 g/dL at 0 months and improved to 11.29 g/dL at 12 months for adolescents. The prevalence of anemia reduced significantly with WIFS over one year. Education and awareness for dietary diversification, increasing bioavailable iron, fortified food for full-term infants and children, and additional supplements are crucial to prevent iron deficiency anemia.

Cysticercosis is a systemic parasitic disease caused by the larval form of cestode Taenia solium. It has a worldwide distribution and is potentially harmful with variable clinical manifestations. The most commonly involved sites include eye, brain, bladder wall, and heart. Ocular cysticercosis can be extraocular or intraocular and may present with varied clinical symptoms. We report the condition in a thirteen year old female child who presented with mild lower lid swelling and diplopia in upgaze, wherein cysticercus cellulosae cyst was found within the mass of the right inferior rectus muscle. It becomes important to report this case because of the relative rarity of the condition these days, unusual site of the cyst and the young age of the patient.

Background: The study was conducted to understand various factors affecting waiting time spent by the patients in outpatient department (OPD) and to provide recommendations for reducing the waiting time in OPD of the selected hospital. Methods: It was a descriptive cross-sectional pretested questionnaire-based study involving all new 100 consenting patients at OPD recruited into the study using a systematic sampling technique after calculating the sampling interval. Results: The study indicates that 70% of patients were satisfied and only 30% were dissatisfied with the attention given by the OPD staff, cleanliness, attentiveness of doctor but shows great dissatisfaction regarding the waiting time spent by them in the outpatient department. Most of the subjects gave the reason for their satisfaction despite more time because of expertise of the doctor, behavior of the doctor, association of hospital with non-government organizations and insurance companies for free medicine and surgery. The dissatisfaction was not because of lack of administration but because of low level of awareness amongst patients attending the OPD about internet booking of appointment, COVID protocols, priorities given to recommendations given by other doctors/VIPs and walk in OPDs attended without prior appointment. Conclusions: A very important observation which evolved from the study was the version of patients that waiting time does not matter because they want to be treated from same doctor due to his/her expertise. Second important observation was that the addressing and greeting of patient by his/her name gave a great satisfaction and level of comfort to patients and affects the waiting time.

Delhi National Capital Region (Delhi NCR) is facing serious challenges linked to worrying levels of air pollution (mainly NO2, PM10 and PM2.5). The CADTIME prject (Clean Air in Delhi through Implementation, Mitigation and Engagement) aims to understand what is required to deliver significant reductions in levels of air pollution. This paper presents the results of the first stage of the project: it firstly contextualises the challenges of air quality management in Delhi within the broader evolution of environmental policies and governance in India, with particular consideration to the tensions between environmental protection and the country's development objectives. Secondly, it sets out how CADTIME will combine multiple source qualitative and quantitative data to develop an air quality action plan and an implementation strategy. In particular, through two workshops with local and national experts and stakeholders, and two rounds of focus groups with citizens of Delhi we will contrast stakeholders' priorities and preferences for existing and potential solutions to air pollution with citizens' lived experiences, thus assessing the political/technical feasibility and public acceptability of current and proposed measures. Furthermore, we will complement the primary qualitative data with a critical review examining the successes and failures of UK and European policies to draw lessons that can be relevant for Delhi and to avoid ineffective policies and achieve cost-effective solutions for the city in the shortest possible time.

Independent Consultant, and Sanjiv Goyal, Fluor Enterprises ments. The oil-film seal commonly used in earlier compressor designs has been mostly phased out by DGSs. More than 80% of centrifugal compressors today are manufactured with a DGS (Stahley 2001). Considerations for retrofitting compressors with oil-film seals to DGSs are presented in Southcott et al. (1995).The DGS system offers many advantages over the oil-film-seal system:Lower gas-leak rates to atmosphere. Simpler and lower equipment weight because this does not require oil-circulation equipment-good for oil and gas offshore applications, where space and weight are important considerations. Reduced power consumption because there is no oil pumping or stripping of sour oil. In DGS systems, the horsepower required for gas shear is reduced by 95% of that of oil shear, which is an important aspect in very large compressors such as those used in liquefied-natural-gas (LNG) plants.Reduced hookup time and lower maintenance because this system does not have an elaborate seal-oil system such as overhead tank, oil pump, coalescing filter, or heaters. Seal-oil ingress to the process leads to the contamination of process gas (discharge side). For the DGS, the seal gas is chosen to be compatible with the process gas and does not risk any contamination. Process gas is known to dissolve in seal oil and will require degassing before pumping to seal, and cleaning before disposal. If the process gas contains H 2 S or NH 3 , disposal of such toxic gases from the seal oil would require extra care. There is no such problem associated with the DGS. For the very-highpressure compressors handling high content of H 2 S or NH 3 in the process gas, oil-film seal is considered unsuitable, and DGS is the preferred choice. Working Principles of DGSThe essential parts of a DGS consist of two mating rings: rotating and stationary. When the compressor is not running, the rings are held in close contact by a spring. When the compressor is spinning, hydrodynamic forces created by the etched grooves on the rotating ring will force the stationary ring against the spring, creating DZRUNLQJJDSWRȝPEHWZHHQWKHWZRULQJV Fig. 1 shows a typical tandem DGS that is widely used in the hydrocarbon industry. (The secondary seal functions as an additional barrier between the process gas and atmosphere and as a backup seal in the event of primary-seal failure.) Using this as an example, the gas-flow path through the DGS can be traced.Filtered gas is injected into the seal to prevent the casing gas from migrating to the seal gap. In addition, the seal gas will also make up for the leakage that occurs across the seal faces. A major portion of the injected seal gas (typically >80%) travels by means of the inner labyrinth seals and into the compressor casing, mixing with the process gas. The seal-gas pressure has to be greater than that which is in the primary seal (typically 25 psig greater, as recommended by the manufacturer).The balance of the flow (typically <20% of injected gas) will account for the ga...
