Tabassum Nazia 한국외국어대학교 인도연구소 2009 남아시아연구 Vol.15 No.1

This study attempts to identify the socio-economic characteristics, costs, returns and profitability, based on the functional analysis through the private poultry farming in Kishoreganj district in Bangladesh. In total of 150 poultry farms were randomly selected taking 50 from each category(small, medium and large). The field level data were collected by direct interviews with broiler farmers using survey questionnaires. This study found that cost of feed, cost of day‐old‐chicks, cost of human labor and veterinary charge were key and important inputs for profitability of poultry farms. The elasticities of broiler farms were 0.46, 0.90, 0.55 and 0.63 for small, medium, large and all broiler farms respectively. It is also observed that the summation of elasticity of different inputs for broiler farms was less than one, implying that the production function exhibited decreasing returns to scale i.e., doubling the inputs will less than double the output.

On the Spectral Efficiency of Multiuser Scheduling in RF-Powered Uplink Cellular Networks

Tabassum, Hina,Hossain, Ekram,Jahangir Hossain, Md,Dong In Kim IEEE 2015 IEEE TRANSACTIONS ON WIRELESS COMMUNICATIONS Vol.14 No.7

<P>This paper characterizes the spectral efficiency of an uplink radio frequency (RF)-powered macrocell network considering harvest-then-transmit protocol such that the macrocell users transmit in the uplink while replenishing the energy from their serving base station (BS) in the downlink. Using the theory of order statistics, a tractable mathematical framework is developed to derive the uplink spectral efficiency and the downlink power consumption resulting due to wireless energy transfer. The framework captures the impact of the locations of the users that are selected for uplink transmission, their channel statistics for information and energy transfer, and different user selection schemes. We first analyze the performance of state-of-the-art greedy and round-robin scheduling schemes in RF-powered cellular networks. Closed-form expressions for the minimum power outage probability (i.e., the probability that the selected user is unable to harvest sufficient power for uplink transmission) are also derived. We then develop modified versions of the conventional user selection schemes that improve the spectral efficiency on a given uplink transmission channel with zero power outage probability (i.e., probability of outage due to insufficient amount of harvested power). The developed schemes are shown to outperform the conventional user scheduling schemes in terms of the throughput and energy harvesting time with a trade-off in fairness among users. The accuracy of the expressions is validated via Monte-Carlo simulations. Numerical results highlight the trade-offs associated with the various user selection schemes as a function of network parameters.</P>

D-LIA: Dynamic congestion control algorithm for MPTCP

Tabassum Lubna,Imtiaz Mahmud,조유제 한국통신학회 2020 ICT Express Vol.6 No.4

The congestion control algorithm (CCA) of Multipath TCP (MPTCP) mainly portraits two fundamental challenges to properly utilize the available bandwidth. First, MPTCP should provide an incentive over single-path TCP while not harming any existing single-path TCP flows when sharing the same bottleneck. Second, better utilize the paths by ensuring high throughput with low packet losses. We focus to improve the second goal by implementing a novel technique to dynamically control the decrease factor of the CCA depending on the interval between packet losses. We implemented in Linux kernel and found a significant performance improvement by extensive the Mininet experiments.

Tabassum, Hina,Hossain, Ekram,Ogundipe, Adedayo,Dong In Kim IEEE 2015 IEEE communications magazine Vol.53 No.6

<P>Energy harvesting from ambient sources is emerging as a sustainable and environmentfriendly technique to prolong the lifetime of wireless devices. However, harvesting energy from these sources may not be feasible for quality- of-service (QoS)-constrained wireless applications. As such, dedicated wireless-powered cellular networks (WPCNs) are currently being investigated to ensure the reliability as well as improved battery lifetime of the wireless devices. With emerging WPCNs, a true wireless network can be envisioned, which is free of connectors, cables, and battery access panels, and guarantees freedom of mobility. To illustrate and understand the design requirements of WPCNs, this article first points out the key challenges of designing energy-harvesting cellular networks. These include the doubly near-far problem, the signal-to-noise ratio (SNR) outage experienced by the energy-harvesting devices located toward the cell-edge, the spatial characterization of the SNR outage zone, the additional resource consumption at energy transmitting sources, and the problems related to designing fairness-constrained user scheduling schemes. A brief overview of the related research advancements in WPCNs and a summary of their limitations are then provided. Finally, we list a few suggestions and design considerations that can potentially tackle the major challenges in emerging WPCNs and open up new research directions.</P>

Tabassum Kotagasti 셀메드 세포교정의약학회 2015 TANG Vol.5 No.2

Adolescent menorrhagia is defined as excessive menstrual bleeding from menarche to adolescents. It is a distressing condition both for the patient as well as for her parents. If it is not managed in time itmay pose significant health problems that may leads to blood transfusion. We determined the efficacy of Geru (Red ochre) in controlling the amount and duration of blood flow in patients of Adolescent menorrhagia. This study included 40 teenage girls, who presented with heavy bleeding during menstruation to Outpatient Department, Sameena Maternity Nursing Home, Hyderabad during the year of 2013. Assessment of each case was done by history and Pictorial Blood loss Assessment Chart (PBAC) score. Geru powder was given for 2 cycles and results were assessed. The data was analyzed statistically. The mean PBAC score before treatment was 497.04 ± 389.92and after trial in 1stand 2ndit was found to be 471.13 ± 162.18 and 310.13 ± 142.15 respectively. On basis of results it was concluded that single unani drug Geru is enough in controlling bleeding and was found effective by its astringent and styptic properties.

Tabassum, Umaira,Reddy, Obula,Mukherjee, Geetashree Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.9

Background: Breast cancer is the most common malignancy with the highest incidence rates among women worldwide. Triple-negative breast cancer (TNBC) disease is diagnosed more frequently in younger women, and is associated with a poor prognosis. Elevated levels of serum haptoglobin protein (Hp) are observed in many malignant diseases including breast cancer. We evaluated the expression and prognostic value of Hp among patients with TNBC. Materials and Methods: Serum Hp levels were determined by Elisa in 41 patients with TNBC and 10 normal individuals. Hp status was correlated with other clinico-pathological parameters including patient survival. Results: Of the 41 patients with TNBC, Hp over expression was detected in 24 (59%) by Elisa. Hp up-regulation was confirmed by Elisa based quantification in the serum of 41 TNBC patients against lower grades and 10 normal individuals. Survival analysis revealed that Hp ($p=2.016{\times}10^{-5}$), stage ($p=2.166{\times}10^{-5}$), distant metastasis ($p=2.217{\times}10^{-5}$), tumor size ($p=1.053{\times}10^{-5}$), and tumor grade (p=0.001), correlated with patient survival on univariate analysis. Multivariate analysis revealed that Hp (p=0.001), and grade of the disease (p=0.008) were independent predictors of survival. Conclusion: Our results indicate that serum levels of Hp may play a role as a potential serum biomarker and prognostic indicator among TNBC patients. Thus, Hp may present a new promising prognostic biomarker in TNBC patients, but independent validations are now necessary for confirmation.

Tabassum Kotagasti,Nishad Rias 셀메드 세포교정의약학회 2015 셀메드 (CellMed) Vol.5 No.3

Dysmenorrhea is the most common gynecological disorder in women of reproductive age. The prevalence of menstrual pain is relatively high and has been shown to be related to many factors like age, age at menarche, menstrual cycle regularity, parity, cigarette smoking, and dietary habits etc. This study was conducted to determine the possible link between dysmenorrhea and the factors related to it. We investigated the associated risk factors that could influence menstrual pain. This Cross Sectional Study was conducted at Dept. of OBG, NIUM, Bangalore. The study consisted of 230 women between the ages of 20 - 49 years. Included volunteers were newly married, nulliparious and parous women. The detailed reproductive history was recorded and was analyzed statistically. It was observed that there were only two factors that were influencing Dysmenorrhea namely the early age at menarche and increase parity. It was hypothesis that earlier start to reproductive life in some way decreases the sensitivity of the uterus to prostaglandin, whereas delayed menarche and postponing reproductive life increase sensitivity of the uterus to prostaglandins and cause severe menstrual pain. It is concluded that early age at menarche and high parity decrease menstrual pain.

( Tabassum Zafar ),( Ab Qayoom Naik ),( Vinoy K. Shrivastava ) 한국축산학회 2018 한국축산학회지 Vol.60 No.4

Background: Mice are widely accepted research models of great clinical significance. Maintenance of laboratory mice breed is an essential aspect for performing research activities in various fields of science. Infanticide is one of the prominent causes of litter loss during maintenance of laboratory mice stock. The present study is an effort to monitor the effect of change in ambient temperature of female mice below the normal range on cannibalism and infanticide during early postparturition phase. Adult female Swiss albino mice have been divided into two groups of control and treatment. On the day of litter group one was maintained under controlled temperature conditions (minimum 20 °C to maximum 23 °C) throughout, while female mice belong to group two have been exposed to variation of room temperature (maximum 15 °C to minimum 10 °C for two nights and one day) until 36 h postparturition. Results: The effects of temperature changes were observed on the infanticide behaviour of dams along with the survival of pups in early postparturition phase till 36 h after delivery. The significant statistical difference (P < 0.05) was reported in infanticide behaviour of dams when control and treatment group was compared. It is observed that decrement in surrounding temperature promotes decrement in the ambient body temperature of dams during early postparturition. It is proposed that alteration of hypothalamic homeostasis due to temperature change induces cannibalism and infanticide behaviour. Lack of thermoregulation during early postparturition creates the sense of insecurity, in-satiety, anxiety and stress. Conclusions: Authors strongly recommend the maintenance of body and surrounding temperature to prevent infanticidal behaviour and cannibalism within Swiss albino mice population. Further investigations are advisable to authenticate the active behavioural and biochemical pathway behind the phenomena.

Tabassum, Ifrah,Mahmood, Humera,Faheem, Mohammad Asian Pacific Journal of Cancer Prevention 2016 Asian Pacific journal of cancer prevention Vol.17 No.7

Background: There has been much research work in the past to ascertain the association between type 2 diabetes mellitus and breast cancer, but definitive evidence has been scanty. The present study was carried out to determine the association of type 2 diabetes mellitus with breast cancer in the female population of Northern Pakistan. Materials and Methods: This case-control study was carried out in the Oncology Department of NORI Hospital. A total of 400 patients were included. Data were entered into PSPP 0.8.1. Two-tailed significance tests were used and a p-value of 0.05 was considered significant. Results: There were a higher percentage of postmenopausal women in the diabetic breast cancer patients' group as compared to the non-diabetic subset. The odds ratio for the association between diabetes and risk of developing breast cancer was elevated with statistical significance (OR = 2.96; 95 % CI =1.3-6.3; p-value=0.004). The results of our study showed that diabetes is associated with a risk of developing breast cancer, especially in postmenopausal women (OR = 4.928; 95 % CI = 2.1-11.3; p-value=0.001). The association was particularly marked in obese subjects (OR = 31.49; 95 % CI = 1.8-536; p- value=0.01), as compared to non-obese subjects (OR = 0.642; 95 % CI = 0.2-1.7). Conclusions: Diabetes is strongly associated with obesity and it tends to increase the risk of breast Cancer, especially in postmenopausal women. A high-risk subset for breast cancer comprised postmenopausal, diabetic and overweight women.

Isolation of 4,5- <i>O</i> -Dicaffeoylquinic Acid as a Pigmentation Inhibitor Occurring in <i> Artemisia capillaris</i> Thunberg and Its Validation <i> In Vivo</i>

Tabassum, Nadia,Lee, Ji-Hyung,Yim, Soon-Ho,Batkhuu, Galzad Javzan,Jung, Da-Woon,Williams, Darren R. Hindawi Publishing Corporation 2016 Evidence-based Complementary and Alternative Medic Vol.2016 No.-

<P>There is a continual need to develop novel and effective melanogenesis inhibitors for the prevention of hyperpigmentation disorders. The plant<I> Artemisia capillaris</I> Thunberg (Oriental Wormwood) was screened for antipigmentation activity using murine cultured cells (B16-F10 malignant melanocytes). Activity-based fractionation using HPLC and NMR analyses identified the compound 4,5-<I>O</I>-dicaffeoylquinic acid as an active component in this plant. 4,5-<I>O</I>-Dicaffeoylquinic acid significantly reduced melanin synthesis and tyrosinase activity in a dose-dependent manner in the melanocytes. In addition, 4,5-<I>O</I>-dicaffeoylquinic acid treatment reduced the expression of tyrosinase-related protein-1. Significantly, we could validate the antipigmentation activity of this compound<I> in vivo</I>, using a zebrafish model. Moreover, 4,5-<I>O</I>-dicaffeoylquinic acid did not show toxicity in this animal model. Our discovery of 4,5-<I>O</I>-dicaffeoylquinic acid as an inhibitor of pigmentation that is active<I> in vivo</I> shows that this compound can be developed as an active component for formulations to treat pigmentation disorders.</P>
