ENGLISH: THE NEED OF TODAY’S WORLD
Samina Bakhtawar Boghani
The Dawn Journal , 2012,
Abstract: Language is one of the components which frame our feelings into words. Globally, out of many languages English is a well-known language considered as the ladder to develop oneself in this cosmos. Lulia Ene says “Generally people who really have got something to say, whose desire is to share their message or beliefs worldwide are compelled to use English”. (p. 01). I agree with this quote that all of us are largely depending on English language to express ourselves. But, there are many others who are still unaware of the brighter side of the English language. This paper will explore the possible reasons for not adapting English language as part of our societies in Pakistan and will recommend some strategies to overcome these hurdles. This paper will also discuss the causes behind the controversy on adopting English language as part of Pakistani context including cultural constrain, lack of confidence among learners and lack of human resources to teach English language.
Nucleosynthesis in Hot and Dense Media  [PDF]

Journal of Modern Physics (JMP) , 2014, DOI: 10.4236/jmp.2014.55040
Abstract:

We study the finite temperature and density effects on beta decay rates to compute their contributions to nucleosynthesis. QED type corrections to beta decay from the hot and dense background are estimated in terms of the statistical corrections to the self-mass of an electron. For this purpose, we re-examine the hot and dense background contributions to the electron mass and compute its effect to the beta decay rate, helium yield, energy density of the universe as well as the change in neutrino temperature from the first order contribution to the self-mass of electrons during these processes. We explicitly show that the thermal contribution to the helium abundance at T = m of a cooling universe (0.045 percent) is higher than the corresponding contribution to helium abundance of a heating universe (0.031 percent) due to the existence of hot fermions before the beginning of nucleosynthesis and their absence after the nucleosynthesis, in the early universe. Thermal contribution to helium abundance was a simple quadratic function of temperature, before and after the nucleosynthesis. However, this quadratic behavior was not the same before the decoupling temperature due to weak interactions; so the nucleosynthesis did not even start before the universe had cooled down to the neutrino decoupling temperatures and QED became a dominant theory in the presence of a high concentration of charged fermions. It is also explicitly shown that the chemical potential in the core of supermassive and superdense stars affect beta decay and their helium abundance but the background contributions depend on the ratio between temperature and chemical potential and not the chemical potential or temperature only. We calculate the hot and dense background contributions for m = T = μ. It has been noticed that temperature plays a role in regulating parameter in an extremely dense systems. Therefore, for extremely dense systems, temperature has to be large enough to get the expected value of helium production in the stellar

Magnetic Dipole Moment of Neutrino  [PDF]
Samina S. Masood
Journal of High Energy Physics, Gravitation and Cosmology (JHEPGC) , 2015, DOI: 10.4236/jhepgc.2015.11001
Abstract: We recalculate the magnetic moment of neutrinos in a hot and dense medium. The magnetic dipole moment of neutrinos is modified at high temperature and chemical potential. We show that the magnetic dipole moment of electron neutrino does not get a significant contribution from thermal background to meet the cosmological bound. However, chemical potential contribution to the magnetic moment is non-ignorable even when chemical potential is an order of magnitude greater than the electron mass. It is demonstrated that this effect is more significant in the models with an extended Higgs sector through neutrino mixing.
WOMEN EMPOWERMENT & FERTILITY BEHAVIOUR
SAMINA BADAR
The Professional Medical Journal , 2007,
Abstract: Objective: To find out the relationship, if any, between womenempowerment and their fertility behaviour. Design: A cross sectional descriptive study. Place & duration of study:The study was conducted in selected area of Bahawalpur City. The data was collected from March to June 2003.Subjects & methods: A total number of 872 households were selected by systematic random selection from upper,middle and lower class. Data was collected from eligible respondent (currently married women of reproductive agegroup 15-49 year having at least one child of 3 years age) through a pre-designed questionnaire. Independent variableempowerment of women was calculated by giving score to education, occupation and autonomy at micro level.Dependent variables (fertility and use of contraception) were assessed for significance by applying chi square test.Results: 41.9% high empowered women were in the opinion that birth of a male child did not provide security (p<.001).A strong positive association between level of empowerment and contraception use (P<.001). There is inverserelationship between women empowerment and number of children (<.001). Conclusion: There is strong inverserelationship between women empowerment and fertility while positive association exist with contraceptive use.

The Professional Medical Journal , 2006,
Abstract: Objective: A study was conducted to evaluate the benefits of vaginal hysterectomy versus abdominalhysterectomy in patient with minimal or no prolapse, no pelvic adhesions and size of uterus not larger than 10 weeksof gestation. Design: A retrospective study. Setting: The study was conducted at Department of Obstetrics andGyanecology , Services Hospital Lahore. Subject And Method: Total of 70 cases were included out of which 40 werevaginal and 30 were abdominal hysterectomies. Results: In vaginal group the morbidity was less, no abdominal scar,shorter hospital stay and less socioeconomic burden on the patient. Conclusion: The conclusion made was vaginalprocedure is method of choice when ever applicable.

The Professional Medical Journal , 2007,
Abstract: Objective: To find-out the determinants of malnutrition in children between sixmonths to five years age in Bahawalpur. Study Design: This was an observational descriptive cross – sectional study.Setting: At Paediatric Medicine out – patient department in Bahawal Victoria Hospital, Bahawalpur.. Period: From Feb.2005 to March 2007.Subjects: Eleven hundred children with malnutrition having ages six months to five years. Mainoutcome measures. Determinants of malnutrition in children under – 5 in Bahawalpur. Results: This study consistsof 1100 sick children between the ages six months to five years brought by their parents (mother) to the PediatricMedicine out-patient department in Bahawal Victoria Hospital, Bahawalpur. Only the children with malnutrition(undernutrition) were included in the study population. Mothers of these children were interviewed and clinicalexamination of each child was carried-out to find-out the causes of malnutrition in them. According to Gome’sclassification, 39.45% of them had first degree malnutrition, 37.10%, second degree and 23.45%, third degreemalnutrition. Conclusion: The major causes of malnutrition found in our study population included: Illiteracy; food –fads; poverty; lack of breast-feeding; improper weaning; diarrhea and respiratory diseases. All these factors werestatistically significant.

The Professional Medical Journal , 2000,
Abstract: Objectives: To evaluate the choice of antihypertensive drugs as based on their effect on serum lipid profile.Material & Methods: 40 hypertensive patients, 12 women and 8 men aged 35-60 years having systolicblood pressure equal to or greater than 160mmHg and diastolic between 95-155mmHg were included in thestudy. Patients were taken in 2 groups i.e. group A (n= 20) used Captopril tablet, doses 25-75 mg orally/dayin divided doses and group B (n=20): Hydrochlorothiazide tablets, doses 25-50 mg orally/day in divideddoses. Serum was analyzed for triglyceride, cholesterol and high-density lipoprotein cholesterol (HDL-C).Results: It was observed that Thiazide adversely effects lipid profile and Captopril has significant lipidslowering effect. Conclusion: Thus it seems that Angiotensin converting enzyme inhibitors may have anadvantage over other antihypertensive agents like beta-blockers and Thiazide diuretics as they do notadversely effect serum lipids. Further study with longer duration of therapy on large number of patients isneeded.
PSEUDO CHOLINESTERASE LEVEL
Samina Javed
The Professional Medical Journal , 2001,
Abstract: 200 healthy persons in Punjabi population have been assessed for level of pseudo cholinesterase inmales and females of different age groups (Substrate: butyryl thiocholine iodide). There was no evidenceof any age dependency or sex specific distinction in children (1-10 years) nor were there any age dependentchanges observed in males(15-60 years). In females(10-40 years) an age dependent difference ofcholinesterase values became apparent regardless of pregnancy or use of hormonal contraceptives. The catalyticconcentration was found lower in younger females(12-40 years) than in older ones (above 40 years) whereenzyme level in old age group did not differ from those of males and children.
