Dabas Chitra S.,Whang Claire 한국마케팅과학회 2022 Journal of Global Fashion Marketing Vol.13 No.2

This study aimed to identify drivers and moderators of sustainable fashion consumption (SFC) by reviewing the evolution of SFC research. A systematic review was conducted using 25 years (1995–2020) of SFC research, which resulted in the synthesis of a final sample of 213 studies to determine growth patterns in SFC themes. Studies were divided into 3 periods: Period 1 (1995–2010; emergence), Period 2 (2011–2015; growth), and Period 3 (2016–2020; maturity/expansion). The results indicated that the scope of SFC expanded from product-based to include larger sustainable fashion practices. Consumer values, consumer knowledge, normative influences, and fashion orientation emerged as four major frequently researched themes in SFC research. Potentially problematic issues identified include the lack of understanding of crosscultural differences related to SFC behavior patterns. A future research agenda is proposed, along with suggestions for practitioners.

Dabas, Surender,Dewan, Abhinav,Ranjan, Reetesh,Dewan, Ajay Kumar,Shukla, Himanshu,Sinha, Rupal Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.17

Background: The present study was conducted to evaluate the technical feasibility, safety and adequacy of surgical margins with salvage transoral robotic surgery (TORS) for recurrent or residual head and neck squamous cell carcinoma patients. Materials and Methods: Thirty patients who underwent salvage TORS using the 'DaVinci' robot were enrolled in the study and data related to their surgical time, complications and functional outcome were recorded. Results: The feasibility of salvage TORS in our study was observed to be 100%. Positive margins were encountered in only 6.7% of patients. Mean blood loss was 23.3 ml with no patient requiring blood transfusion. Postoperative complications in the form of primary haemorrhage requiring active surgical intervention occurred in 13.3%. Oral feeding could be started as early as the 3rd postoperative day in a few patients, with nasogastric tubes being removed on the 12th postoperative day. Long term gastrostomy tube dependency was seen in 10% cases. Median survival of patients was 19 months. Conclusions: Salvage TORS is a safe, effective and feasible option in the management of treatment failure cases. It offers an alternative surgical approach with unexpected benefits in terms of tracheostomy tube use, Ryle's tube and gastrostomy dependence.

Dabas, Y.P.S.,Sud, S.C. Asian Australasian Association of Animal Productio 1989 Animal Bioscience Vol.2 No.4

Five multiparous and four nulliparous cross-bred cows were administered s/c with oestradiol-$17{\beta}$ and progesterone 0.1 mg and 0.25 mg/kg. b.w./day for 7 days and 2 mg s/c twice daily of reserpine on days 9 to 12. Lactation was successfully induced in all animals for periods from 258 to 476 days. All animals were dried off for a minimum of 2 months. Subsequently, they were injected s/c with oestradiol valerate and hydroxyprogesterone caproate at 0.1 mg and 0.25 mg/kg. b.w./day on days 1 to 3 and 2 mg twice daily of reserpine on days 8 to 11. Lactation was successfully reinduced in all the cows for a period varying from 228 to 426 days.

TREATMENT OF CYSTIC OVARIAN DISEASE IN COWS WITH GONADOTROPINS

Dabas, Y.P.S.,Atheya, U.K.,Sud, S.C.,Lakchaura, B.D. Asian Australasian Association of Animal Productio 1989 Animal Bioscience Vol.2 No.1

Eighteen multiparous and 8 nulliparous cows with cystic ovarian disease (19 having follicular cysts, 7 with luteal cysts) were administered either 3000 I. U. HCG or $300{\mu}g$ LHRH. Ten animals responded satisfactorily leading to normal estrus within a period of 15 to 30 days and subsequent conception. In 8 animals cysts recurred and no effect of treatment was observed in 3 patients. Plasma progesterone concentration was significantly lower in animals having follicular cysts compared to those with luteal cysts.

TRIALS OF GONADOTROPIN TO REGRESS OVARIAN CYSTS PROVOKED BY HORMONAL INDUCTION OF LACTATION

Dabas, Y.P.S.,Sud, S.C. Asian Australasian Association of Animal Productio 1992 Animal Bioscience Vol.5 No.2

Successful induction of lactation in 5 nulliparous repeat breeding cows was achieved by administering diethyl stillboestrol (0.1 mg/kg B.W.) and hydroxyprogesterone caproate (0.25 mg/kg B.W.) for 3 days followed by reserpine (4 mg/day) for 4 days, and dexamethasone (16 mg/day) for one day. The treatment caused cystic ovarian condition in all the animals. Intravaginally progesteronesoaked sponges suppressed but did not eliminate the behavioural estrus. Administration of LHRH ($300{\mu}g$) regressed the cysts in all animals in the first instance but the cysts reappeared in 2 animals. One animal became pregnant and delivered a normal calf.

A NOTE ON THREE-DAY STEROID THERAPY FOR INDUCTION OF LACTATION IN INFERTILE HEIFERS

Dabas, Y.P.S.,Sud, S.C. Asian Australasian Association of Animal Productio 1989 Animal Bioscience Vol.2 No.4

Estradiol-$17{\beta}$ and progesterone at the rate of 0.1 and 0.25 mg respectively, per kg body weight per day were administered s/c to each of the five infertile feifers for 3 consecutive days i.e. days 1 to 3, and 2 mg of reserpine were followed twice daily on days 8 to 11. Results indicated that three of the treated heifers were successfully induced into lactation. Progesterone concentrations in the blood plasma and defatted milk exhibited considerable variations.

MODELING OF A HELICALLY COILED HFC134a EVAPORATOR

J. K. DABAS,SUDHIR KUMAR,A. K. DODEJA,K. S. KASANA 대한설비공학회 2014 International Journal Of Air-Conditioning and Refr Vol.22 No.3

A computer simulation model has been developed for the performance analysis and design optimization of a helical coil and cylindrical shell type evaporator working with HFC-134a by using the appropriate empirical correlations of heat transfer coefficient and pressure drop in the helical tubes as available in the literature. This model is based on a numerical method of cell discretization of shell side and tube side of the evaporator. The local values of variables are calculated and the mass, momentum and energy balance is applied to each small cell. The whole sequential and iterative procedure to satisfy the boundary conditions has been transformed in the computer codes. The model has been validated by comparing with the actual results of an experimental study which is also a part of this work. A detailed analysis of the effects of varying input parameters of both fluids on the performance of evaporator was carried out with the help of this model. It also gives the optimum values of mass velocity of refrigerant and the helical tube diameter against the available flow conditions of refrigerant and of external fluid and the required degree of vapor superheat at the exit of evaporator. Thus it provides an easy solution in both the cases of either the performance optimization of an existing evaporator or the design optimization of a new evaporator. The inherent errors in the outcome of correlations for heat transfer, pressure drop and refrigerant properties are the limitations of this model.

EXPERIMENTAL INVESTIGATION OF A REFRIGERATION SYSTEM WORKING UNDER TRANSIENT CONDITIONS

J. K. DABAS,SUDHIR KUMAR,A. K. DODEJA,K. S. KASANA 대한설비공학회 2014 International Journal Of Air-Conditioning and Refr Vol.22 No.3

The impact of transient conditions along with varied capillary tube length and charge quantity over the performance of a simple refrigeration system under all time transient operations has been investigated in a specially designed experimental setup. A maximum drop of 75% in the coefficient of performance (COP) of the system was recorded by the end of the transient cooling period. The continuous deterioration in performance from start to end of the transient cooling job can be well minimized by the optimum selection of capillary tube length and charge quantity. This paper refers some of the existing methods to determine the appropriate length of the coiled capillary tube and charge quantity for a newly designed refrigeration machine working under steady state conditions and compares the experimental results of transient operation with these. Optimum charge quantity for transient operation in the present study is 3.5% to 5% less than that calculated by the existing analytical and numerical methods. The optimum length of coiled capillary tube for transient operation as found in this experimental study matches approximately with the length predicted by the existing dimensionless correlation on the basis of design parameters as estimated towards the end of the transient cooling period.

Capturing sustainable fashion purchase behavior of Hispanic consumers in the US

Davis Lizhu,Dabas Chitra 한국마케팅과학회 2021 Journal of Global Fashion Marketing Vol.12 No.3

Despite the vital role Hispanic consumers play in the U.S. apparel market, research on their sustainable apparel consumption behavior is limited. This study investigated the influence of normative expectations on young Hispanic consumers’ organic apparel purchasing behavior. A self-administered online survey was used to collect data from a population of Hispanic college students. The proposed conceptual model was tested using structural equation modeling (SEM). The study results revealed that social norms did not directly influence organic apparel purchase behavior of Hispanic consumers. Instead, social norms determined personal norms and organic apparel knowledge, which then affected the purchase behavior. Perceived health benefits also significantly affected young Hispanic consumers’ purchase behavior of organic apparel. We also found that organic apparel knowledge significantly affected the perceived quality and health benefits of organic apparel. This study contributed to the literature by 1) understanding the complex relationships of social norms with personal norms, organic apparel knowledge, and organic apparel purchase behavior of Hispanic consumers, and 2) incorporating perceived product value into the conceptual model. Findings of this study can help sustainable apparel manufacturers and retailers to develop effective marketing strategies for targeting Hispanic consumers in the US apparel markets.
