    The thesis topic is located in the domain of numerical simulation of laminar flames. The principal aim of the presented research is the study of numerical techniques for the multidimensional simulation of flames with low computational costs. Present work is divided into three parts: First part is related to the development of a C++ simulation code for 1D laminar premixed flames. In the second part, a new technique to account for differential diffusion effects is proposed, which is based on tabulated chemistry methods. The third part focuses on the analysis of partially premixed flames. A dedicated one-dimensional flame code is discussed for the simulation of complex/detailed chemistry and diffusion processes in premixed laminar flames. This code is written in C++ and is able to use different diffusion models (Fickian, Hirschfelder and Curtiss). The code yields accurate solutions of the major parameters as well as pollutant formation, both in the flame zone as well as downstream in the post-flame region. Results prove the accuracy of the code when compared to experimental data. Following, a new technique is proposed to include differential diffusion effects into flamelet models. This approach is developed in the context of tabulated chemistry methods.The technique is based on correcting the progress-variable of flamelet models. The main feature of the proposed technique is the use of only one progress variable equation (1D manifold) without requiring a second parameter. This correction technique allows including detailed chemistry effects at low-cost in numerical simulation of multidimensional flames. A series of simulations are carried out for various flames. The results are excellently matched with full model solutions/detailed chemistry solutions. The flamelet solutions databases, namely premixed and non-premixed, are further tested for partially premixed flames. This study is based on the investigation of partially premixed flame using single mode flamelet database solutions. For the verification of database solutions, finite rate chemistry simulations are also carried out to solve partially premixed flames. 3D jet coflow simulations are performed for three different level of premixing and results are compared with experimental data. The results show good agreement along with capabilities and limitations of flamelet databases solutions.El tema de la tesi es troba en el domini de la simulació numèrica de les flames laminars. L'objectiu principal de la investigació presentada és l'estudi de tècniques numèriques per a la simulació multidimensional de flames amb baixos costos computacionals. El treball actual es divideix en tres parts: La primera part es relaciona amb el desenvolupament d'un codi 1D de simulació C ++ per flames laminars premesclades. A la segona part, es proposa una nova tècnica per explicar els efectes de difusió diferencial, que es basa en mètodes de química tabulada. La tercera part se centra en l'anàlisi de flames parcialment premesclades. Es discuteix un codi de flama unidimensional dedicat per a la simulació de processos complexos i detallats de química i difusió en flames laminars premesclades. Aquest codi està escrit en C ++ i és capaç d'utilitzar diferents models de difusió (Fickian, Hirschfelder i Curtiss). El codi proporciona solucions precises dels paràmetres principals, així com la formació de contaminants, tant a la zona de la flama com a la regió posterior a la flama. Els resultats demostren l'exactitud del codi en comparació amb les dades experimentals. A continuació, es proposa una nova tècnica per a incloure efectes de difusió diferencial en models de flamelet. Aquest enfocament es desenvolupa en el context dels mètodes tabulats de química. La tècnica es basa en la correcció de la variable de progrés dels models de flamelet. La característica principal de la tècnica proposada és l'ús d'una única equació de variable de progrés (espai 1D) sense necessitat d'un segon paràmetre. Aquesta tècnica de correcció permet incloure efectes químics detallats a baix cost en la simulació numèrica de flames multidimensionals. Una sèrie de simulacions es realitzen per diverses flames. Els resultats mostren una concordància excel·lentment amb solucions completes/detallades de la química. Les bases de dades de solucions de flamelet, a saber premesclades i no premesclades, es sotmeten a proves addicionals per flames parcialment premesclades. Aquest estudi es basa en la investigació de flames parcialment prebarrejades utilitzant solucions de base de dades monomode. Per a la verificació d'aquestes bases de dades, es realitzen simulacions de química de velocitat finita per resoldre flames parcialment premesclades. Es realitzen simulacions de flux d'aire en 3D per a tres nivells diferents de premescla i els resultats es comparen amb dades experimentals. Els resultats mostren un bon acord juntament amb les capacitats i limitacions de les solucions de bases de dades de flamelet.Postprint (published version

    Background: Unregulated growth of population is the most important problem that is hindering the socio-economic growth of a developing country like India since its independence. Multiple socio-economic factors are responsible for non-acceptance of contraception. To meet the unmet need these factors are needed to be explored. The current study aimed to assess the rate of acceptance of different contraceptive methods, various socio-demographic factors affecting acceptance and to find out the reasons for non-acceptance among married women of reproductive age group in a rural area of West Bengal.Methods: An institution based cross sectional study was conducted among 224 married women of reproductive age group with the help of a predesigned, pretested schedule.Results: Almost entire study population (98.2%) had the knowledge of any modern accepted method of contraception; health personnel (91.1%) being the most common source of knowledge. In majority of cases (69.6%) the decision of contraceptive use was taken by the husband and wife jointly. The overall prevalence of current use of contraception was 33.9% of which most common method adopted was found to be tubectomy (42.1%). The total unmet need was 50%. Multivariate analyses revealed that women aged more than 27 years, belonging to Hindu religion, nuclear family of higher per capita income with education of self and husband being up to or above middle level, having at least two leaving issue and one male child had higher odds of ever use of contraception.Conclusions: To bridge the gap of knowledge and practice intense awareness generating programmes focusing on the local barriers of contractive practice were the need of the hour to address this alarming public health problem

    Background: Menstruation and menstrual hygiene are still issues which are insufficiently recognized in Indian society and influenced by misconceptions and socio‐cultural restrictions. Adolescent girls become vulnerable to reproductive tract infections resulted from lack of knowledge and faulty practices regarding menstrual hygiene. The study aimed to assess the impact of health education programme regarding knowledge, attitude and practice of menstrual hygiene on genitourinary tract morbidities among adolescent girl students in a slum area of Kolkata.Methods: A quasi experimental study was conducted in two Government secondary schools located in a slum area under Kolkata Municipal Corporation. The study consisted of three steps. First a baseline survey with the help of a pre designed pretested questionnaire was done to find out the socio-demographic information, existing knowledge, attitude and practice of menstrual hygiene of the students and presence of any genito-urinary tract morbidities was documented. This was followed by an intervention phase of 6 months during which weekly lecture and interactive classes were taken in the study school. Second step was reassessment of K.A.P of menstrual hygiene and documentation of related morbidities at post intervention. Third step was to follow them for another 3 months for final reassessment of the same.Results: There was statistically significant decrease in the genito-urinary tract morbidities with improvement of mean K.A.P score of menstrual hygiene in study school from the pre-test level to post-test level as compared to the control school. But there was a significant decline of mean menstrual hygiene score at follow up of 9 months in the study school depicting lack of sustainability of the heath educational programme.Conclusions: Sustained health education programme with regular reinforcement and active involvement of the mothers regarding menstrual hygiene can lead to better reproductive health of adolescents

    Background: An organized cytological screening (Pap smear) is the mainstay for cervical cancer prevention and control programme. Financial and logistic burden of operating such a program is considerable. This has prompted the evaluation of alternative feasible techniques. It appeared from the earlier studies that visual inspection with lugol’s iodine (VILI) could be a potential alternative to cervical cytology. VILI is a low cost, easy to apply and highly sensitive technique. It gives result immediately thus allows doctors to “see and treat” at first visit. Objective of present study was to evaluate the performance of visual inspection with lugol’s iodine and its comparison with cytology in cervical cancer screening.  Methods: 400 non-pregnant reproductive age women were subjected to Paps and VILI in this prospective study done in a tertiary-care centre in Delhi. Reference standard used for all was colposcopy and colposcopic-directed biopsy (when required).Results: Of 400 Pap smears done 11.75% were normal, 77.5% inflammatory, 5.5% had ASCUS, 0.25% ASC-H, 0.5% AGUS, 2% LSIL, 1.5% HSIL and invasive cancer in 0.5%. With LSIL and above smears as significant, the sensitivity and specificity of Paps were 50% and 97.66% respectively. VILI was positive in 12.8% of cases. Sensitivity and specificity of VILI was 85.5% and 89.9% respectively. Overall accuracy of VILI in detecting pre-invasive lesion was 89.7% while with pap smear it was 96%.Conclusions: Accuracy of VILI and Pap smear in detecting pre-invasive cervical lesion was comparable. At tertiary-care centers VILI can be used effectively to screen the patients with significant lesions. Patients can be directly subjected to further treatment at the earliest thus reducing loss to follow-up

    Get PDF
    Introduction: About 29-60% of tribal children are underweight due to limited healthcare access. The Kols, a tribe in central India, face similar issues and our study will examine their complementary feeding practices. Methodology: A sequential explanatory mixed-method research design was conducted on 218 Kol tribe women in the Manikpur block of Chitrakoot district Uttar Pradesh. In the first phase, the quantitative interview using a semi-structured questionnaire and in the second phase, an in-depth interview of 20 Kol mothers was conducted using an interview guide. Results: About 52.3% of the women were aged between 26- 35 years, and about 83.9% were illiterate. About half of the children (n=116, 53.5%) were introduced to complementary feed at 6-8 months of age. The independent predictors of the timely initiation of complementary feeding were education (AOR: 2.422, p 0.037), age of the mothers (AOR: 1.2106, p 0.047) and the number of children of the mothers (AOR: 2.715 p 0.004) diet diversity was rarely maintained. Conclusion: Complementary feed was introduced timely for half of the tribal women but diet diversity was not maintained. Health education and counselling to utilize locally available food items should be encouraged

    Juvenile aggressive ossifying fibroma is a rare, benign tumor of the maxillofacial region that is aggressive and recurrent leading to multiple surgeries causing maxillofacial defect and deformities. The management of patients with ossifying fibroma is controversial.  The aim was to report a case of huge ossifying fibroma involving maxilla, zygoma, and orbit in a young female with a duration of 15 years. The patient was operated multiple times but the lesion recurred. Patient-specific implant was fabricated to replace the defect area which would be created after surgery but with meticulous intraoperative decision the high morbid surgery was changed to conservative surgery. No recurrence was seen after two year follow up. The patient aesthetic has also improved. In conclusion it can be said in huge benign ossifying fibroma morbid surgery should be avoided

    Background: College students show higher prevalence of mental health issues as compared to the general population. Unfortunately, this year, students all over the world have to face, added pressure due to COVID-19. This study aimed to estimate the effect of COVID-19 pandemic and lockdown on the mental health of Medical and Engineering Students. Subjects and methods: The study was carried out at different medical and engineering colleges in Bihar, Delhi and Maharashtra, and Tamil Nadu. 699 responses were collected and analyzed during the study period. Data was collected by email/ online platform through Google form via non- probability Sampling Technique. Mental health status was determined by using Corona virus anxiety screening (CAS), GHQ (General Health Questionnaire)-12, GAD (General Anxiety Disorder)-7 scale and PHQ (Patient Health Questionnaire)-9 scales.369 (53%) MBBS and 330 (47%) Engineering students participated in the study. Results: Maximum participants in both groups did not have anxiety related to COVID-19 (MBBS (96.8%) and Engineering (95.2%). About two-third participants secured above cut off score i.e., MBBS (62.3%) and Engineering (64.8%) in GHQ-12. Approximately comparable proportion in both groups were found to have severe anxiety and depression (16% vs 20%), when applied GAD-7 and PHQ-9. Uncertainty in the timing of the exams/ Academic delay was found to be the most worrying factor (MBBS, 41.19% vs Engineering 31.82%). Conclusions: About two-thirds of medical and engineering students psychologically equally affected by current pandemic in our study. A student wellness clinic is the need of hour in current scenario, which is supported by mental health experts (Psychiatrists, Clinical Psychologists) and residents on rotation basiswhere all psychological problem including Stress, Anxiety, Interpersonal crisis, Relationship issues and Personality problems of the students are dealt effectively in institute campus near to student residential area
