FHBC, a Hexa‐\u3cem\u3eperi\u3c/em\u3e‐hexabenzocoronene–Fluorene Hybrid: A Platform for Highly Soluble, Easily Functionalizable HBCs with an Expanded Graphitic Core

Materials based upon hexa‐peri‐hexabenzocoronenes (HBCs) show significant promise in a variety of photovoltaic applications. There remains the need, however, for a soluble, versatile, HBC‐based platform, which can be tailored by incorporation of electroactive groups or groups that can prompt self‐assembly. The synthesis of a HBC–fluorene hybrid is presented that contains an expanded graphitic core that is highly soluble, resists aggregation, and can be readily functionalized at its vertices. This new HBC platform can be tailored to incorporate six electroactive groups at its vertices, as exemplified by a facile synthesis of a representative hexaaryl derivative of FHBC. Synthesis of new FHBC derivatives, containing electroactive functional groups that can allow controlled self‐assembly, may serve as potential long‐range charge‐transfer materials for photovoltaic applications

Factors Affecting the Effectiveness of Social Media for Recruitment: An Exploratory Factor Analysis Approach on Private Universities in Bangladesh

Social media are crucial weapons which are used as online recruitment tool at present time.  The study is designed to explore the most crucial factors which affect the effectiveness of social media for recruitment. This paper is basically prepared based on 50 respondents from 10 private universities of Bangladesh to understand the cost and time effectiveness of social media for recruitment. Data used for this study have been collected by using a structured questionnaire of 5 point Likert scale which consists of 15 specific questions. The study is conducted by factor analysis and attained 4 factors including Information Quality, Privacy & Security, Cost & Time and User Friendly that influence the effectiveness of social media for recruitment.  Another statistical tool t-test has been also used to prove the hypothesis. The study also reveals that these four factors are in satisfactory level. From the study concerned people in this arena can get a specific view about the factors that directly influence the effectiveness of social media for recruitment and take corrective actions to improve the present situation. Keywords: Social Media, Social Media Recruitment, Benefits of Social Media Recruitment, Factor Analysis and T-test

The relationship between modified Graeb score and intraventricular hematoma volume with Glasgow outcome scale and modified Rankin scale in intraventricular hemorrhage of brain: a comparative study

Background: Intraventricular hemorrhage (IVH) is an acute neurosurgical condition. The aim of this study was to identify the relationship between modified Graeb score (mGS) and intraventricular hematoma volume with Glasgow outcome scale (GOS) and modified Rankin scale (mRS).Methods: This is a Quasi-experimental study conducted in the department of neurosurgery, Chittagong Medical College Hospital, Chittagong, Bangladesh during the period from 24 July 2018 to 23 July 2019. After a detailed history and clinical examination, 150 patients were selected for this study. The study participants were divided into two major groups- external ventricular drainage (EVD) and conservative; both groups consisted of 44 patients. Written informed consent were taken from the participants. Data were analyzed using statistical package for the social sciences (SPSS) software.Results: Overall mean age was around 60 years with an age range from 15-85 years. More than three fourth of the patients in both groups were from the age group of >50 years (73.83%). There were no differences between EVD and conservative groups regarding medical comorbidities. Most prevalent comorbidity among the patients of both groups’ hypertension, followed by diabetes and previous ischemic stroke. Overall the most frequent symptoms in the studied patients were vomiting, followed by loss of consciousness, headache and convulsion. There were no significant differences between the two groups regarding presenting symptoms. The mean Glasgow coma scale (GCS) score level was significantly lower in the patients with EVD than their counterpart from 1st post-operative day to 8th post-operative day. However, within-group comparison shows that the GCS score was significantly increased from 1st day to 8th day in both groups of patients.Conclusions: These findings can be used to identify patients in whom an EVD may provide measurable outcomes benefit with respect to patient mortality and help guide neurosurgical decision-making in particular patient subgroups with acute IVH

Vaginoplasty in vaginal agenesis associated with MRKH syndrome with tabularized peritoneal pull-through

In this paper, a 16 year old girl who was  diagnosed as a case of Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, underwent a combined laparotomy-peritoneal approach to create a neovagina by using tubularized peritoneal graft with uneventful postoperative period. Vaginal dilation was maintained with a vaginal mould daily for six months and three to four times weekly thereafter. She was followed-up after 2 and 4 weeks in the first month and three monthly for a duration of six months. On second follow-up, adequate vaginal length of 6-7 cm and width of 2.5-3 cm were achieved with healthy vaginal tissue. Hence, the laparotomy-peritoneal approach of using a peritoneal graft for creations of a neovagina can be  an effective approach  with  minimal  surgical morbidity to  create  a passageway for satisfactory intercourse

Factors Affecting the Level of Health Care Worker's Stigmatized and Discriminatory Attitude Towards People Living with HIV: a Study at the Dr. Zainoel Abidin General Hospital, Banda Aceh, Indonesia

The aim of this study was to identify the level of health care worker`s (HCW) stigmatized and discriminatory (S&D) attitude towards people living with HIV (PLHIV) and the factors that influenced this attitude. This research was conducted at the Dr. Zainoel Abidin General Hospital (RSUDZA) in Banda Aceh province of Indonesia. A cross-sectional study design was adopted for this research. Eighty nine HCWs were included in this study and they were selected purposively. Pearson correlation analysis, analysis of variance or independent sample t test analysis was used according to the type of data. We found that the level of S&D attitude towards PLHIV in RSUDZA is high. Based on the Least Significant Difference Test, the average score of the answers between nurses and general practitioners and between nurses and medical students was significantly different(p=0.05). Pearson correlation analysis showed that the levels of S&D attitude towards PLHIV was positively correlated with age (r=0.219, p=0.04) and irrational fear of HIV transmission (r=0.352, p=0.001) and negatively correlated with knowledge about HIV/AIDS (r=-0.336, p=0.001). Pearson correlation analysis also found that knowledge of HIV/AIDS negatively correlated with the irrational fear of HIV transmission (r=0.382, p=0.000). In addition, the level of S&D attitude towards PLHIV was also associated with marital status of HCWs (p=0.020). Gender, education level, religion and the importance of religion in HCW lives wasn`t significantly affect to the level of S&D attitude towards PLHIV in HCW. We concluded that the factors that influence the level of S&D attitude towards PLHIV among the HCW are age, marital status, knowledge of HIV/AIDS, irrational fear of HIV transmission and HCWs occupations. To reduce S&D attitude towards PLHIV among the HCWs, we recommend introducing some program to increase knowledge of HIV/AID

Regeneration potential of seedling explants of chilli (Capsicum annuum)

A study was conducted with hypocotyl, cotyledon and shoot tip of chilli as explants for regeneration on MS medium supplemented with different concentrations and combinations of auxins and cytokinins. Regeneration potential was determined by two ways. One is regeneration of shoot via callus formation from hypocotyls and cotyledon explants; another was direct shoot regeneration from shoot tip explant. The highest callus was induced from hypocotyl in a combination of BAP (5.0 mgL-1) with NAA (0.1 mgL-1) and cotyledon in a combination of BAP (5.0 mgL-1) with IAA ((1.0 mgL-1). The callus induction as well as shoot initiation was higher in hypocotyls than cotyledon. Shoot tips regenerated into plantlets directly with sporadic small callus at the base. Shoot elongation was accelerated by using additional supplementation of GA3 and AgNO3. Regenerated shoots rooted best on the MS medium supplemented with 0.1 mg L-1 NAA + 0.05 mg L-1 IBA
