Evaluation of Deferral Causes Among Voluntary Blood Donors in Chennai â€“A Retrospective Study

Background: Prospective blood donors may be unable to donate blood for several reasons that could either compromise their own health or affect the safety of the blood donated. To ensure the safety of blood supplied by the blood bank to patients, it is paramount that all blood donors are in good health. This ensures the donor is protected by his/her own health and the recipient is protected against transfusion of transmissible diseases, drugs or contaminated products that would be detrimental to their health. This study aims to evaluate the various causes for Deferral among Voluntary Blood Donors. Materials and Methods: A Retrospective study was conducted to analysis the various causes of Deferral, over a period of 6 years, from January 2006 to December 2011, among different age groups of both the Sex at The Department of Transfusion Medicine, The TN Dr MGR Medical University, Chennai, India. Results: A total of 11,324 donors were registered, of which 1188 donors were deferred (10.49%) for various reasons. Of the total donors, females constituted only 10.5%. Deferral was more among female (90%) than in male (10%). The common causes in female were Low hemoglobin levels, Menstruation, underweight, and Low blood pressure. The deferral was higher in the age group of 18-25 years and the most common cause was Low hemoglobin level. In male, the various common reasons were High blood pressure, Low hemoglobin level & Intake of medicines or Alcohol in recent 24 Hrs. The deferral rate varied from 10 to 15% in the past five years but the most common cause of deferral in our study was similar every year. Conclusion:The Major cause or deferral is low haemoglobin and under weight. Since Hb level is not constant for a individual and it can be fluctuated daily, a deferral for a low Hb does not mean a donor is anemic and permanently deferred. Counseling and Information about how to increase Hb level should be provided to donors.
Immunoarchitecture of Distinct Reticular Fibroblastic Domains in the White Pulp of Mouse Spleen

The development of peripheral lymphoid tissues requires a series of cognate interactions between hemopoietic and stromal cell populations, including reticular fibroblasts, which form the mesenchymal scaffolding of distinct tissue compartments. Here we describe the formation of different fibroblastic domains in the mouse spleen white pulp by using two new rat monoclonal antibodies (MAbs). In the white pulp, MAb IBL-10 labels both T- and B-cell zone reticular elements at various intensities. The IBL-10hi subset was found primarily at the edge between the peripheral part of the PALS and follicles, and the IBL-10lo compartment was distributed evenly within the white pulp. The IBL-10hi subset appeared during the first 2 postnatal weeks and was absent in SCID mice. The white pulp fibroblast subset identified with MAb IBL-11 had a different tissue distribution and kinetics of ontogeny, with an appearance overwhelmingly restricted to the PALS and a narrow rim at the edge of the follicular border area toward the marginal zone. The appearance of IBL-11–positive reticular cells was delayed compared with that of the IBL-10lo–positive subset. The formation was independent of the influence of antigen receptor–bearing lymphocytes, as evidenced by the presence of IBL-11–positive fibroblasts in SCID mice. By transferring various lymphocyte subsets into SCID mice, partial compartmentalization of the white pulp fibroblasts could be induced, indicating that these mesenchymal fibroblast precursors retain their ability to differentiate upon encountering mature T- or B-cells.
Parametric study on static and dynamic characteristics of bump-type gas foil thrust bearing for oil-free turbomachinery

Gas foil bearings have bright application prospects in oil-free turbomachinery such as aircraft air cycle machines, compressors and gas turbines. To extend the applicability of foil bearings to high-speed and heavy-load systems, the axial force produced primarily by the pressure difference between the turbine and compressor sides must be taken into consideration. The thrust disc of the rotor is typically used to sustain the axial force and maintain the attitude of the rotor in a rotor-bearing system. In an analytical model used to predict the performance of gas foil thrust bearings (GFTBs), fluid–structure interaction must be considered because of the coupling effects of hydrodynamic lubrication and the compliance of bearing surface. In this study, a link-spring structural model was employed to calculate the equivalent vertical stiffness of the bump foil. This model exhaustively considered the effect of three factors: flexibility of the bump foil, interactions between bumps, and frictional forces at the contact surfaces. In addition, top foil deflection that directly affects film thickness is calculated using a finite-element shell model. The static and dynamic characteristics of GFTBs were predicted after solving the steady-state Reynolds equation and two linearized dynamic coefficient equations which were obtained with perturbation method by using finite-difference method. The structural deformation equation was substituted into the Reynolds equations in the calculation process. The calculated static load was compared with the published experimental data, and the results validated the theoretical analysis. Thereafter, the static and dynamic characteristics including impact of rotational speed, initial minimum film thickness and the ratio of the inlet to outlet film thicknesses were analyzed. Parametric studies were also conducted to evaluate the effect of different structural parameters of the bump foil and journal tilting on the static characteristics of GFTBs. Because the proposed analytical model is completely algebraic, it can be easily programmed for accurately and effectively investigating the performance of GFTBs.
Apparatus for Preparing Thermoplastic Composites

The properties of high performance composites with semi-crystalline thermoplastic matrices are dependent upon the processing conditions during manufacturing. To study the relationship between processing and material properties, a low cost molding apparatus was developed and evaluated. This apparatus is capable of processing both thermoplastic composite and pure thermoplastic polymer test specimens at controlled combinations of cooling rate, molding temperature and consolidation pressure. It consists of a water cooled aluminum mold, a high flow rate water pump and a hydraulic molding press with heated platens. A description of the molding apparatus is presented along with a detailed descrip tion of the molding procedures used to fabricate and anneal both composite and pure polymer specimens. Using this apparatus specimens of carbon fiber/PEEK and PEEK polymer composites were molded at cooling rates ranging from 0.01 °F/min up to as high as 21,000°F/min. Differential Scanning Calorimetry (DSC) testing showed specimen crystallinities ranging from 0 to 45 percent crystallinity are readily obtainable.
Mathematics Teacher's Perspective of Their Students' Learning in Traditional Calculus and Its Teaching Strategies

We conducted a survey with the objective of studying the teachers` perspective of their students` learning in traditional calculus and its teaching strategies. This survey was targeted at mathematics teachers of the junior colleges, polytechnics and universities in Singapore. In this paper we present findings of the first part of our survey. The first part addresses various issues related to the mathematics teachers` perception of the current status of calculus education in Singapore. The findings of this study will be unique in Singapore context because, according to the best of our knowledge, no such survey on calculus education has ever been undertaken in Singapore.
SEASONAL VARIABILITY AND TRENDS OF THE MIAMI URBAN HEAT ISLAND

Urban areas tend to be consistently warmer than their rural surroundings due to altered evapotranspiration properties (Taha 1997), increased anthropogenic heat output (Oke 1982), and higher heat capacities of urban substrates (Swaid 1991). The induced horizontal temperature gradients associated with urban heat islands (UHIs) are known to influence convection and subsequent mesoscale circulations (Baik et al. 2001), thus having the potential to modify precipitation distribution within, and adjacent to, the urban center (Shepherd et al. 2002, Dixon & Mote 2002, Dou et al. 2013). Aside from confirming its existence (Debbage & Shepherd 2015, Kandel et al. 2016), relatively little work has been conducted on the Miami urban heat island. The city’s unique climate and topography further increase the need for such a study. The primary goals of this study largely remain unchanged: to 1. verify the presence of the Miami Urban Heat Island (UHI), 2. assess its strength and variability, and 3. evaluate its potential influence on precipitation distribution in south Florida when considered in relation to convective steering flow. Aside from the incorporation of additional datasets, previously discussed methodology is also retained. This document will discuss the supplementary data sources utilized, expound on previously discussed methodology, and discuss results acquired during Summer/Fall 2017 and Spring 2018.
Attitudes toward Tattoos in the Work Place

This article examines the perceptions of tattoos in the workplace. Our hypothesis predicted there would be a difference between men and women in how tattoos are perceived in the workplace. A questionnaire was completed by undergraduate students to evaluate how they perceive tattoos. There was no significant difference in perceptions of men compared to women as they relate to tattoos in the workplace. However, there was a significant difference in the perceptions of the participants, regardless of gender, for individuals whose tattoos were visible compared to their perceptions of the same people picture without visible tattoos. Overall, while tattoos continue to become more and more popular; there continues to be a negative stigma associated with tattoos. How tattoos are perceived in the workplace may be important for applicants to consider as they begin to explore employment opportunities.
REPRODUCTIVE STRATEGIES IN THE POSTPARTUM DAIRY COW WITH REFERENCE TO ANOVULATION AND POSTPARTUM UTERINE HEALTH

of Thesis Presented to the Graduate School of the University of Florida in Partial Fulfillment of the Requirements for the Degree of Master of Science REPRODUCTIVE STRATEGIES IN THE POSTPARTUM DAIRY COW WITH REFERENCE TO ANOVULATION AND POSTPARTUM UTERINE HEALTH By Katherine E. M. Hendricks August 2004 Chair: L. F. Archbald. Major Department: Veterinary Medical Sciences In Experiment 1, a total of 155 cows with ovarian cysts was sequentially allocated to 3 groups on the day of diagnosis (Day 0). Cows in Group 1 (n = 55) were treated with GnRH (100 μg, im) on Days 0 and 7, PGF2α (25 mg, im) on Day 14, GnRH (100 μg, im) on Day 16, and timed inseminated (TAI) 16-20 h later. Cows in Group 2 (n = 49) were treated with GnRH on Day 0, PGF2α on Day 7, GnRH on Day 9, and TAI 16-20 h later. Cows in Group 3 (n = 51) were treated with GnRH on Day 7, PGF2α on Day 14, GnRH on Day 16, and TAI 16-20 h later. Pregnancy was determined by rectal palpation 45-50 d after TAI. On both Days 0 and 7, cows in all groups were subjected to ultrasonography (U/S) and blood samples were obtained for determination of progesterone concentration (P4). Cows in Groups 1 and 2 were more likely to have a CL and high P4 on Day 7 compared to cows in Group 3. There was no significant difference in pregnancy rate (PR) between cows in all groups, but cows with a CL on Day 7 were more likely to become pregnant. It was concluded that administering GnRH to cows with ovarian cysts 7 days
Skateboard Injuries in Children

(one with a fractured skull, mentioned above) and 8 others had minor head injuries (without obvious soft tissue trauma). There were no significant associations between the age of the child and the nature or severity of the injury. The incidence of fractures in the 5 to 9 age group was 36 per cent, as compared with 42 per cent in the 10 to 15 age group: the incidence of head injury was 4.3 per cent in the younger children and 5.6 per cent in the older ones: the incidence of joint injury was 14.9 per cent in the younger and 10.7 per cent in the older ones. There were no significant differences in the grades of injury. Forty-nine per cent of the injuries in the 5 to 9 age group were graded 3
Comparison between interrupted vertical mattress suture versus skin stapler versus subcuticular suture for skin closure in clean surgery

BACKGROUND: To compare skin closure in clean surgery with three different technique i.e. Vertical mattress suture, Skin stapler and Subcuticular suture. MATERIAL AND METHOD: 162 patients who undergone clean surgery were studied to compare three types skin closure techniques i.e. stapler, subcuticular suture using Polyglactin suture and vertical mattress suture using polyamide suture. Group A: 53 patients having skin closure with skin stapler.Group B: 56 patients having skin closure with subcuticular skin suture and Group C: 53 patients having skin closure with interrupted vertical mattress. All the patients were assessed for operative time required for skin closure, cosmetic outcome, patient comfort, post operative complication and pain. RESULT: Time required for skin closure was minimum with stapler. Average Speed of skin closure by stapler was 12.06 cm/min, by subcuticular it was 1.16 cm/min and with vertical mattress average speed was 1.25 cm/min. Local site pain was observed more in stapler group patients as compared to others. Patient comfort was maximum with subcuticular suture technique of skin closure. Suture removal was more painful in vertical mattress suture and least painful in subcuticular suture. Post operative surgical site infections were more in stapler and vertical mattress group patients and less with subcuticular suture technique. Subcuticular suture resulted in superior scar formation as compared to staple and vertical mattress suture. Patient satisfaction was maximum with subcuticular suture technique and least with vertical mattress suture technique of skin closure. CONCLUSION: Subcuticular suture are superior than other two in terms of incidence of post operative wound infection, cosmoses and patients acceptability. With Skin stapler technique time required for wound closure is minimum but it is costly.
A National Survey of School Counselor Supervision Practices: Administrative, Clinical, Peer, and Technology Mediated Supervision.

Supervision is vital for personal and professional development of counselors. Practicing school counselors (n = 1557) across the nation were surveyed to explore current supervision practices. Results indicated that 41.1% of school counselors provide supervision. Although 89% receive some type of supervision, only 10.3% of school counselors receive weekly supervision from another school counselor. Most school counselors receive supervision from principals (62.8%). Approximately 32% engage in supervision with other mental health professionals. Only 5.1% of school counselors engage in technology-mediated supervision. Implications, limitations, and future directions for research are provided.
The role of estrogen receptors in the contribution of constrictor prostanoids to aortic coarctation-induced hypertension

The Role of Estrogen Receptors in the Contribution of Constrictor Prostanoids to Aortic Coarctation-Induced Hypertension. (December 2008) Minga Miown Sellers, B.S., Texas A&M University Chair of Advisory Committee: Dr. John N. Stallone This study investigated the effects of selective estrogen receptor (ER) agonists on constrictor prostanoid (CP) function and on the development of mean arterial pressure (MAP) in aortic coarctation-induced hypertension (ACIH). Female Sprague-Dawley rats were divided randomly into four groups: intact (INT), ovariectomized (OVX), OVX + ERα selective agonist (4, 4’, 4”-(4-Propyl-[1H]-pyrazole-1, 3, 5-triyl)trisphenol; OVX+PPT), or OVX + ERβ selective agonist (2,3-bis(4-Hydroxyphenyl)-propionitrile; OVX+DPN). Rats were then subjected to abdominal aortic coarctation (hypertensive, HT) or sham surgery (normotensive, NT). PPT, DPN or vehicle treatments were given daily as a subcutaneous injection. MAP was measured every other day at 2-14 days after coarctation. Mesenteric arterioles were harvested 12-14 days after coarctation for isometric tension studies to examine concentration-responses to VP. Basal and VPstimulated prostanoid release and mRNA and protein levels of ERα and ERβ (using real time RT-PCR and immunoblotting) were measured in separate groups of arterioles. MAP was higher in INT-HT, OVX+PPT-HT and OVX+DPN-HT than in OVX-HT after 12 days. Vascular reactivity to VP was greater in OVX+PPT-NT rats than in other groups.
MENTAL ILLNESS AND LENGTH OF HOSPITAL STAY FOR MEDICAID INPATIENTS INFECTED WITH HIV

OBJECTIVE: Study associations of length of inpatient stay (LOS) for HIV-infected Medicaid recipients with; Severe Mental Illness History (SMI-H), Other (Less Severe) Mental Illness History (OMI-H), and diagnosis with Acute Mental Illness (AMI) during the inpatient visit. DATA SOURCE & COLLECTION / STUDY SETTING: Merged 1992-98 Medicaid claims and HIV/AIDS surveillance data obtained from the State of New Jersey for adults with ≥1 inpatient stay after an HIV/AIDS diagnosis from 1992-1996. STUDY DESIGN: Observational study of 8,186 HIV patients with 31,515 inpatient visits. SMI-H, OMI-H and Primary/Secondary AMI diagnosis at visits were ascertained from ICD–9-CM Codes; 11% of visits had an AMI diagnosis while 25% and 29% of visits, respectively, were from patients with SMI-H and OMI-H histories. PRINCIPAL FINDINGS: HIV patient-stays with Primary or Secondary AMI diagnoses each had mean LOS=11.0 days and stays of patients with SMI-H and OMI-H had mean LOS of 10.4 and 11.8 days, respectively compared to a mean LOS=12.7 days for stays of patients with no history of mental illness. But after adjusting for measures of HIV disease severity and health care access in multivariate models, patients presenting with primary and secondary AMI diagnoses had ~32% and ~13% longer LOS, respectively, than did similar patients without AMI (P<0.001). In the absence of a diagnosed AMI, SMI-H and OMI-H alone were not related to LOS in adjusted models. However, in adjusted models, SMI-H was associated with ~20% shorter time to readmission for a new visit. CONCLUSIONS: This study concurs with previous findings of greater (adjusted) LOS for HIV patients that have mental cormibidity. But the patterns seen here suggest that the increase may be mediated by extra time required to treat acute mental illnesses occurring at the visit rather than from mental illness interfering with treatment and discharge of HIV conditions.
Neglected Disease; Genital Tuberculosis

Objective: The aim of this study is to emphasize the importance of genital tuberculosis on infertility. Materials and Methods: One hundred and eighteen patients had laparotomy with various indications who applied to the Infertility Unit of Obstetrics and Gynecology Outpatients Clinic of the University of Cukurova in a period between 1st January 1984 to 1st January 1999. Results: Genital tuberculosis has been diagnosed incidentally in 16 out of 118 patients. 11 of them had primary and 5 of them had secondary infertility. The incidence of genital tuberculosis was 13.5%. The mean age of patients was 27.8. Discussion: Since nowadays genital tuberculosis is neglected, it seems that because of imigration atypical forms of tuberculosis will be reborn both in developed and also in developing countries.
Understanding the Role of Mentor Teachers during Teaching Practice Session

Abstract Mentor teachers have become key players in launching student teachers into the teaching profession. Mentor teachers are recognized for their practical knowledge of the teaching profession, which complements the theoretical knowledge that the student teacher has acquired from the university. This paper therefore investigated how mentor teachers understand and perceive their roles as they prepare University of South Africa (UNISA) student teachers for their teaching careers during teaching practice session in cooperating schools. This study adopted a mixed methods research design because of its ability to incorporate both quantitative and qualitative data collection techniques. A total of 46 mentor teachers filled in the questionnaire and 15 of them were also interviewed to gather more qualitative data to enrich the study. Findings reveal that mentor teachers understood their roles to be that of facilitating socialization of student teachers into the teaching profession, by assisting them to gain competence in the various areas of the school functioning, including lesson planning and presentation; classroom management and appropriate use of teaching strategies and resources.The mentor teachers also demonstrated understanding of the concept of ‘mentoring’, but they needed feedback from UNISA to assure them if student teachers are being assisted according to the institution’s expectations. This indicates that UNISA still needs to do more to enhance the roles and responsibilities of mentor teachers in supporting student teachers.

Prenatal Diethylstilbestrol (DES) Exposure

It is estimated that up to six million personsmothers, daughters, and sons-were exposed to DES during its use for high-risk pregnancy between 1940 and 1971. The most widespread use of DES during pregnancy was probably between 1946 and 1960. However, its administration continued between then and 1971, when the association between intrauterine exposure to DES and the rare development of vaginal and cervical clear cell adenocarcinoma was described. ’ 1
The representation of plural inflectional affixes in English: evidence from priming in an auditory lexical decision task

ABSTRACT The representation of inflection is controversial: theories of morphological processing range from those that treat all inflectional morphemes as independently represented in memory to those that deny independent representation for any inflectional morphemes. Whereas identity priming for stems and derivational affixes is regularly reported, priming of inflectional affixes is understudied and has produced no clear consensus. This paper reports results from a continuous auditory lexical decision task investigating priming of plural inflectional affixes in English, in plural prime-target pairs such as crimestrees. Our results show statistically significant priming facilitation for plural primes relative to phonological (cleansetrees) and singular (crimetrees) controls. This finding indicates that inflectional affixes, like lexical stems, exhibit identity priming effects. We discuss implications for morphological theory and point to questions for further work addressing which representation(s) produce the priming effect.
