Published: August 2024

Geopolymer, with its notable benefit of low carbon dioxide emissions, holds the potential to substantially curtail environmental pollution. According to the existing related research on geopolymer materials, it is obvious that it has great development potential in many engineering application fields, and it is a new generation of green and environmentally friendly recycled materials. Nowadays, there is a growing concern regarding explosion protection. Explosions near buildings can cause catastrophic damages on the building external and internal structure, and the most important thing is that can cause injuries and loss of life to the occupants of these buildings. This study investigates the mechanical performance of the fiber-reinforced geopolymer concrete under explosive testing. Furthermore, the finite element analysis models have been established through LS-DYNA software to simulate the explosive testing using Structure-Arbitrary Lagrangian Eulerian Method (S-ALE). The model is used to assess the dynamic mechanical behavior of geopolymer materials.

Published: August 2024

Journalism’s societal role hinges on effective communication, demanding proficient language skills. This study assesses a South African University of Technology’s Department of Journalism, probing existing selection methods’ efficacy in predicting success in two English modules. Concerns persist about these methods accurately identifying students with essential language proficiency. The research explores alternatives for better assessing language abilities crucial for journalistic proficiency. The literature review underscores language proficiency’s significance in journalism education, especially in African contexts, observing challenges faced by South African universities. Current practices, relying on high school English grades and standardised tests, may not precisely reflect required journalism-specific language skills. Using a non-experimental quantitative design, the study analyses correlations between selection methods and student performance in English modules. Findings indicate a weak correlation, advocating for a more comprehensive approach with alternative assessments. Proposed alternatives include writing samples, portfolio reviews, and situational judgement tests for a holistic selection process. The study suggests future research directions, emphasising broader generalisability and exploring correlations with practical skills and critical thinking. The study emphasises the imperative for journalism departments to reevaluate and enhance selection criteria, aligning them with dynamic professional demands.Contribution: This article contributes to journalism education by illuminating the shortcomings of current selection methods in assessing potential for success in English language-related modules. It proposes alternatives and advocates for a holistic approach, providing practical insights for journalism departments aiming to align their selection criteria with the evolving demands of the profession. Ultimately, this contribution aids in the development of skilled journalists.

Authors: Bisai Santanu , Dutta Swati , Sengupta Debjani , Ghosh Pramit
Published: August 2024

Introduction:

Severe acute malnutrition (SAM) is a life-threatening condition affecting under-five children. Nutritional rehabilitation centers (NRC) were designed to provide comprehensive clinico-social management of SAM children at an institutional setting.

Materials and Methods:

The study was based on record analysis of 6 years between 2014 and 2019 after obtaining ethical and administrative approval. The objectives were to compare indices such as admission rate, bed occupancy, and sex-differentials over time as well as among different NRCs.

Results:

A total of 7316 children were admitted in the 9 NRCs. Quarterly admission ranged between 181 and 389. Gender parity index was higher for girls. Cure rate ranged between 39.8% and 70.9%; subtle modification in diet helped in improving cure rate. Bed-occupancy rate varied from 72.55% to 85.95%.

Conclusion:

Variability of performance of NRCs could be associated with factors such as available manpower, attitude of providers, and supply of logistics. Regular interaction with community and counseling is necessary to increase admission and hospital stay.
Dermatoglyphic pattern is an Indicator for Assessing the Intelligence Quotient (IQ) of Medical Undergraduates in A North Indian Medical College
Authors: Singh Archana , Singh Arun
Published: August 2024

Introduction:

The intelligence quotient (IQ) levels and dermal ridge patterns on the volar surfaces of digits and palms of different individuals may be related because brain developed from 13th to 21st week and during same time-period the dermal groove developed. Neocortex is a higher center for learning and of intelligence, so there is association between Intelligence level and patterns of fingerprints. So, this study was conducted to find out the different dermatoglyphic patterns of fingers and palms and correlate them to the IQ levels of medical undergraduates.

Materials and Methods:

Fingers and palms prints of both the hands of 150 medical students of 18-24 years were collected with help of ink pad and A4 size of paper. The fingers and palms prints were studied using hand held magnifying lens and their IQ levels assessed using Raven’s Standard Progressive Matrices.

Results:

The most common finger patterns e.g. single whorl in thumb, ulnar loop in index finger and middle finger of both sides and were found on participants having Grade I Intelligence. More males shown higher IQ and belonged to Class A IQ i.e. grade I and Grade II however in lower IQ the males and females were equally distributed and belonged to Class B i.e. Grade III, IV, V. Most common finger patterns i.e. single whorl in thumb and ulnar loop in index on both right and left side were found in the participants having Grade I & II Intelligence.

Conclusion:

Students with Grade I and II IQ has higher incidence of whorl followed by loop whereas in participants with IQ level of Grade III onwards, loop was the most common pattern followed by whorl. Asymmetry in patterns on both the side of fingerprint was evident in lower IQ levels. Higher values of mean ‘a-b’ ridge count and mean ‘atd’ angle was higher in individuals with low IQ level. So, it can be concluded that the dermatoglyphic pattern and IQ levels are associated.
Metabolic Syndrome and Skin
Authors: Ambalal Sujata Mehta
Published: August 2024

The metabolic syndrome (MetS) has become a global crisis and is believed to affect almost one-quarter of the world's population. Its prevalence has been rising, especially in the younger age group. The interactions of the skin and MetS are myriad. Physiological functions of the skin may confer a protective role, whereas cutaneous diseases may play the role of MetS initiator or amplifier. Cutaneous signs may be some of the earliest manifestations of insulin resistance, the basic pathophysiology behind MetS. Skin changes are also prominent in type 2 diabetes mellitus, the consequence of MetS. Drugs used in dermatological disorders can lead to metabolic dysfunction. Awareness about the risk factors and early lifestyle interventions can help delay or even prevent the life-threatening complications of this syndrome. Dermatologists are in a unique position to predict and prevent MetS or its complications, a long time before the patient visits a physician for systemic problems. To write this review, an internet search was made focusing on articles on skin problems associated with MetS and its components, its risk factors, pathogenesis, and ways to prevent it. Information relevant to dermatological practice was compiled.

M. , Bose S. K. , Jamadar Saleem , Shah Monal , Tank Bharat , Dhabhai Ravindra , Mittal Sanjay Kumar , Bhushan Premanshu , Pandita Akshi , Barve Vaibhav
Published: August 2024

Background:

Treatment of vitiligo is still a challenge in dermatology. Literature is sparse on the definitive clinical role of basic fibroblast growth factor (bFGF) in vitiligo patients.

Aims:

We decided to generate a consensus in an attempt to answer some critical questions related to the management of vitiligo and the role of bFGF.

Materials and Methods:

A Delphi method among 21 experts across India was conducted. A consensus (agreement was 75% or greater) was taken on 27 statements on the prevalence, epidemiology, and treatment of vitiligo and the role of bFGF in the management of vitiligo. The consensus process was completed after two rounds.

Results:

Topical corticosteroid therapy is the first-line therapy for vitiligo; however, its adverse effects are widely known, especially in sensitive areas. Topical calcineurin inhibitors are preferred in stable vitiligo of the face, neck, genitals, or intertriginous regions as an alternative to topical corticosteroids. Topical bFGF is a relatively newer therapy with a promising role in stable vitiligo. bFGF is safe and effective in inducing repigmentation of vitiligo lesions. Combination therapy of bFGF with other topical therapies, phototherapy, and surgical procedures can be beneficial in patients of vitiligo.

Conclusion:

This consensus would complement the currently available literature on bFGF and help the practitioner to recognize the unmet need in the treatment of vitiligo.
Analyses of the clinical and immunological characteristics of patients with lupus erythematosus
Authors: Deng Min , Wu Ruifang , Zhou Xingyu , Su Yuwen , Li Yaping
Published: August 2024

Background:

Lupus erythematosus (LE) is a broad-spectrum, heterogeneous disease. At one end of the spectrum is the cutaneous LE (CLE) without systemic involvement, and at the other end is the systemic LE (SLE) with multisystem involvement. Analyses of clinical and immunological indicators and pathological examinations are helpful for early diagnosis, differential diagnosis, and prognosis of LE.

Aim and Objectives:

We described the clinical and laboratory characteristics of patients with LE and assessed the diagnostic value of immunohistochemical detection of C3d, C4d, IgG, IgG4, and CD123 in skin lesions of LE.

Materials and Methods:

Clinical and laboratory data of 62 patients with LE were collected. The expression levels of C3d, C4d, IgG, IgG4, and CD123 in skin lesions of LE were detected by immunohistochemistry (IHC).

Results:

Clinical manifestations such as hematological involvement, C3, C4, ESR, hematuresis, proteinuria, anti-Sm, anti-ribosomal P-protein, anti-U1-RNP, anti-histone, and anti-nucleosome antibodies are helpful for classificatory diagnosis of LE. The positive rate of C3d and/or C4d along the basement membrane zone in LE skin lesions by IHC was 74.6%, which was higher than that by direct immunofluorescence (47.5%) (P = 0.002). The expression of CD123 protein and the number of CD123+ plasmacytoid dendritic cells (PDCs) in skin lesions of patients with LE were higher than those of dermatomyositis (DM), while the distributed form of CD123 + PDCs in the dermis was different between LE and DM.

Conclusions:

The diagnosis of CLE and SLE requires a combination of clinical manifestations, laboratory indicators, and pathological examination. Immunohistochemical detection of C3d, C4d, and CD123 in skin lesions is important for the classificatory diagnosis of LE.

Authors: Palaninathan Preetha Srinivasan , Kamalabai Raveendran Arul Salomee , Swaminathan Kesavan Jayachandran
Published: August 2024

Vitex negundo is an aromatic shrub distributed worldwide with several medicinal properties. The alarming and rapid increase in the antimicrobial drug resistance globally has led to the development of alternative therapeutic strategies to overcome drug resistance. Hence, the present study was carried out to evaluate the antibacterial efficacy of the acetone, benzene, ethyl acetate, chloroform, and methanolic leaf extracts of V. negundo against Klebsiella pneumonia (K. pneumonia) using in vitro studies. The sensitivity test against the standard antibiotics showed that the tested K.
pneumoniae was multi drug resistant (MDR) bacteria. Based on the results of the Thin Layer Chromatography (TLC) bioassay, ethyl acetate was selected as the suitable solvent for extraction of V. negundo leaves. The zone of inhibition (ZoI) was observed starting from the concentration of 50 μg/mL for the V. negundo ethyl acetate leaf extract for the selected MDR bacteria K. pneumoniae. The highest ZoI was observed as 18 mm at the concentration of 200 mg/mL. Ethyl acetate leaf extract of V. negundo also expressed MIC value of 1.5 μg/mL against the test pathogen MDR K. pneumoniae. The inhibitory effect of the ethyl acetate leaf extract of V. negundo leaves was apparent from 40 minutes indicating time dependant inhibition or killing of the MDR K. pneumoniae. The results of the present study demonstrate the antibacterial activity of the ethyl acetate leaf extract of V. negundo, which may be attributed to the presence of several secondary metabolites in the extract.

Authors: Bhattacharya Sumanta , Roy Paromita , Chatterjee Uttara , Bhattacharyya Arpita
Published: August 2024

Kaposiform hemangioendothelioma (KHE) is a locally aggressive vascular tumor usually seen in children. It is frequently associated with Kasabach-Merritt phenomenon. Here we report two cases of KHE: the first case being an 11-month-old boy who came with massive swelling on the face and violaceous discoloration. The second case was a 7-year-old boy who presented with respiratory distress and bleeding manifestations. CT scan chest showed a large mass involving the anterior mediastinum. Histologic examination of resected masses from both these cases showed features of KHE involving subcutaneous tissue and thymus, respectively. Although cutaneous and subcutaneous location is common, thymic involvement is unusual. It is important to distinguish KHE from infantile haemangioma, tufted angioma, spindle-cell haemangioma, verrucous malformation and Kaposi sarcoma. Histologic features, supportive immunohistochemistry and the clinical profile together are helpful to differentiate KHE from other vascular lesions.

Authors: Yadav Neha , Singh Manisha , Mishra Atul , Mishra Surendra Prasad
Published: August 2024

Background:

It is essential in modern radiotherapy treatment practices to evaluate the quality assurance (QA) of the treatment plan prior to the exclusion of patient from treatment. The typical suitable tools used for patient pretreatment QA are phantoms representing the human anatomy. An anthropomorphic heterogeneous female pelvic (AHFP) phantom has been developed to represent the real female pelvic structure.

Purpose:

The objective of the current study is to assess the findings of relative dosimetry carried out utilizing an electronic portal imaging device (EPID) on the AHFP phantom fabricated.

Methods:

The planning target volume (PTV) was created on CT slices of an AHFP phantom to confirm the tool’s ability to represent female pelvic anatomy and serve as a QA tool. In order to assess the dose received by healthy organs during radiotherapy, organs at risk such as the bladder and rectum were additionally drawn alongside the PTV. Rapid Arc and Intensity modulated radiation therapy (IMRT) were both used to create the treatment plan on treatment planning system, and the Anisotropic Analytical Algorithm Version 11.0.31 was used to calculate the dose.

Results:

The results obtained for the average gamma value in RapidArc plans are 0.26, 0.27, and 0.28 (g ≤1) and IMRT plans are 0.39, 0.40, and 0.46 (g ≤1) for target 1, target 2, and target 3, respectively.

Conclusion:

According to the findings of the current study, the AHFP phantom was used to explore the potential of relative dosimetry using EPID as a QA tool, which was found to be suitable.
Roles of endoplasmic reticulum stress and activating transcription factors in Alzheimer’s disease and Parkinson’s disease
Authors: Cheng Ching-Feng , Cheng Evelyn , Ku Hui-Chen
Published: August 2024

ABSTRACT

Endoplasmic reticulum (ER) is a crucial organelle associated with cellular homeostasis. Accumulation of improperly folded proteins results in ER stress, accompanied by the reaction involving triggering unfolded protein response (UPR). The UPR is mediated through ER membrane-associated sensors, such as protein kinase-like ER kinase (PERK), inositol-requiring transmembrane kinase/endoribonuclease 1α, and activating transcription factor 6 (ATF6). Prolonged stress triggers cell apoptotic reaction, resulting in cell death. Neuronal cells are especially susceptible to protein misfolding. Notably, ER and UPR malfunctions are linked to many neurodegenerative diseases, such as Alzheimer’s disease (AD) and Parkinson’s disease (PD), delineated by accumulation of misfolded proteins. Notably, ATF family members play key roles in AD and PD pathogenesis. However, the connection between ER stress, UPR, and neuropathology is not yet fully understood. Here, we discuss our present knowledge of the association between ER stress, the UPR, and neurodegeneration in AD and PD. We also discuss the roles of ATF family members in AD and PD pathogenesis. Moreover, we provide a mechanistic clarification of how disease-related molecules affect ER protein homeostasis and explore recent findings that connect the UPR to neuronal plasticity.

Authors:   Human Accom and Design Devices Stds Comm
Published: August 2024

This SAE Recommended Practice describes how to position and posture the H-point design tool (HPD) described in Appendix B, and how to establish the seating reference point (SgRP), design H-point travel path, and other key reference points that are used in the design and specification of both driver and passenger seat positions.

This practice also provides a method for determining the length of the seat track for a driver seat that adjusts fore/aft. The seat track length is based on a desired level of driver accommodation, assuming a U.S. population containing an equal number of male and female drivers. The procedure can be used to establish driver seat track accommodation for new vehicle designs or to evaluate accommodation in existing vehicles.

A general method for determining driver seat track length for any driver population (male and female stature distribution) at any selected accommodation percentile and gender mix is given in Appendix A.

Application of this document is limited to Class A Vehicles (Passenger Cars, Multipurpose Passenger Vehicles, and Light Trucks) as defined in SAE J1100.

Published: August 2024

Enhancement of rural households’ welfare is a concurrent policy objective in Nigeria. This study analyzed the determinants of welfare  among arable crop farmers in the study area. The data for the study were collected from 120 randomly selected farming households and  analyzed using descriptive statistics and censored Tobit regression model. Description of the welfare indicators revealed that the  respondents were in the low to middle-income earning group. Most of the respondents used corrugated iron sheets, cement walls, and  concrete floors. The respondents had little concern for the environment as evidenced by their poor waste disposal and drainage  practices. Results from the regression analysis revealed that, of all the explanatory variables modeled to influence household expenditure  per capita, farm size, household size, and years of schooling were the only significant predictors. Based on the outcome of  this study, a key recommendation is that the government and other key stakeholders ought to emphasize the need for obtaining a high  level of education since education impacted the farmers’ welfare. This will affect their capacity to adopt new technology and their  perception of growing their household size to hire family labor given its significant impact on their expenditure level and, as a result, their  general welfare.

Authors: Alabi D.L. , Napoleon R.B.
Published: August 2024

Most rural households in Nigeria are more familiar with the use of the traditional locust bean condiment in meal preparation than that of  the soybean. This study was carried out to improve the shelf life of the condiments, increase the consumption of soybean for enhanced  nutrition among the resource poor rural households and determine consumers’ acceptability of the powdered locust bean and soybean condiments. Three samples were developed namely: powdered fermented locust bean, powdered fermented soybean and their  composite (50:50 locust and soybean) condiments. Both the proximate composition and sensory assessment of the condiments were  determined. The proximate attributes investigated include protein, carbohydrate, fibre, lipid, ash and moisture contents of the samples  while the sensory evaluation parameters include condiments’ aroma, appearance, colour, taste and texture as well as the overall  acceptability. Results showed that powdered fermented soybean condiment has the highest protein (51.63%), lipid (35.40%) and ash  (11.64%) contents. The composite also has higher protein (51.19%) than locust bean (47. 25%). On the other hand, powdered locust bean  condiment has the highest carbohydrate (4.44%) contents while the composite condiment has the highest fibre content (10.27%). No  significant difference was observed in the overall acceptability of the three samples implying that they are equally acceptable among the  consumers. It can be concluded that the production process of powdered soybean and the composite condiment should be taught to  women in rural areas to enhance protein intake among the low-income rural households who may not be able to afford other expensive  sources of protein.

The purpose of this study was to look at gender stereotypes as determinants factors of female child education in the Ogoja Education Zone of Cross River State. Three research questions were posed, which were translated into three hypotheses. A literature review was conducted depending on the variables being studied. A survey-based research design was used. A sample of female staff members from ten (10) public secondary schools in the education zone were chosen using a simple random selection technique. A 15 items structured questionnaire was   designed for data collection. The reliability index of the instrument ranges from alpha coefficients of 0.64 (for societal factors), 0.73 (for socio-cultural factors); and 0.75 (for the religious factors) was calculated. The data was analysed using the Independent t-test statistical method to evaluate the hypotheses at the 0.05 level of significance. The findings demonstrated that socio-cultural, religious, and societal factors had a substantial impact on the education of girl children in the research area. Based on these findings, it was urged, among other things, that some societies avoid giving preferential treatment to male children; that the government educate parents on the significance of education for both boys and girls; and that a campaign be launched against early marriage.

Published: August 2024

The assessment of heavy metals in the tissues of prawns is essential to understand the extent of contamination and potential health risk in human and the aquatic ecosystem. The study aimed to determine the concentration levels of iron, chromium, lead and cadmium in the tissues of Macrobrachium vollenhovenii of the lower Cross River System comparing it with the permissible consumption limits of Federal Ministry of Environment (FMENV) and the World Health Organization (WHO). Samples of the prawn were collected from artisanal fishermen on landing between November, 2022 and January, 2023. Collected samples were placed on ice and transported to the laboratory for Atomic Absorption Spectrophotometry analysis. The prawn samples had a total length and weight of 18.0cm – 24.0cm and 98.42g – 248.64g, respectively. The results revealed that the toxicity levels of heavy metals in the tissues of M. vollenhovenii ranged as follows: Fe: 1.041 - 2.082mg/kg; Pb:  0.173 - 0.618mg/kg; Cd: 0.114 - 0.242mg/kg; Cr:  0.007 - 0.038mg/kg. The results from the analysis indicated that, Fe had the highest concentration, followed by Pb, Cd and least was Cr. The result revealed that, there was no statistically significant difference in the Lead levels (p=0.266) and chromium levels (p=0.882) across the months (NOV-JAN). There was statistically significant increase in the Iron levels across the months (NOV-JAN) (p=0.037). There was statistically significant decrease in the cadmium levels across the months (NOV-JAN) (p=0.022). Therefore, this study presents valuable information about heavy metals bioaccumulation in a commercially important prawn caught from the lower Cross River which is consumed by locals in the region. Also the evaluation of possible risks on health associated with contaminated prawn consumption on human is clear.  Except for Cr, the heavy metal concentrations in the prawn samples analyzed were above the prescribed limits set by various authorities (WHO/FMENV). The result of this study calls for a close monitoring of anthropogenic activities of the area for safety in seafood consumption by human.

Published: August 2024

Dioscorea rotundata Poir is a primary source of carbohydrate in most African homes, where it is consumed in various forms. This research focuses on the identification of the prevalent fungal isolate responsible for the rot of yam in Calabar metropolis and the effect of these fungi on the nutritional composition of white yam. A survey of the major markets (Akim, Marian, Mbukpa and Watt) showed that the major fungi responsible for the soft rot of yam included Aspergillus flavus, A. niger, Fusarium oxysporium, Penicillium notatum and Rhizopus stolonifer. Aspergillus niger recorded the highest incidence, occurring in all the samples from various locations. The result of the pathogenicity test, proved that Aspergillus niger, Penicillium notatum and Rhizopus stolonifer were the major causes of rot in Calabar metropolis. The proximate analysis of the healthy tubers and those inoculated with Aspergillus niger, Penicillium notatum and Rhizopus stolonifer showed that the infection by these fungal isolates caused significant changes in the nutrient composition of the tubers. The total moisture content of the inoculated tubers increased within a range of 65.43±0.35 – 70.01±0.05% as compared to 59.59±0.12% in the control experiment. The carbohydrate content decreased significantly from 27.87±0.50% to a range of 18.11±0.36 – 22.68±0.28%.

BACKGROUND: Continuing professional development (CPD) is a systematic and ongoing process of education undertaken by health professionals to maintain up-to-date knowledge and development skills.
OBJECTIVE: To assess the level of willingness of Radiographers to undertake continuing professional development in Nigeria.
MATERIALS AND METHODS: A convenience sampling technique was adopted for the study. A self-administered and well-structured questionnaire consisting 21 items with 3 sections; A, B and C was developed. Section A was on the socio-demographic data of the respondents with 7 items. Section B had 12 items that elicited responses on the level of willingness and section C with 2 items that focused on suggestions to encourage CPD. These were distributed online and offline to Radiographers in Nigeria. A total of 100 respondents were recruited for the study: 30 respondents were offline and the remaining 70 via the online route. Across the six geopolitical zones of Nigeria, 30 respondents were gotten from the South-South, 18 from the South-East, 20 from the South-West, 10 from the North-West, 10 from the North-East, and 12 from North-Central. Data was analyzed using the Statistical Package for Social Sciences (SPSS) version 25.0 at a p-value of ≥ 0.05. Statistics used were descriptive statistics which included charts and tables, inferential statistics which include Kruskal-Wallis Test which was used to test for differences in level of willingness across the 6 geopolitical zones. Cochran’s Q test was used to compare the willingness simultaneously. A correlation test using Spearman’s rho was used to assess the relationship between years of working experience and level of willingness. A Chi-square analysis was also used to check for association.
RESULTS: A total of 84 respondents (84%) willingly participated in continuing professional development programme out of the 100 participants used in this study. There was no significant difference in the level of willingness across the six geo-political zones of Nigeria. Lack of finance (41%) and location of programmes (27%) were observed to be the major barriers to continuing professional development. There was also a significant positive relationship between years of working experience and willingness to participate in Continuing Professional Development programmes.  A majority (39%) suggested that the cost of the programmes be reduced and 21% suggested the programmes be decentralized.
CONCLUSION: The study concluded that there is a high level of willingness of graduate Radiographers to undertake continuing professional development in Nigeria. However, the high cost of training and the location of the training programmes are the major barriers.

Entrepreneurial competency consists of specific skills, knowledge and abilities require by entrepreneur to start and manage an enterprise successfully. It consists of both the technical and management components. The skills and knowledge constitute the technical or the hardware component of entrepreneurial competency while management component could be described as the software aspect of entrepreneurial competency needed by the entrepreneur to function well in hardware functions.   To ensure entrepreneurial success, entrepreneur must acquire the needed competencies which could be through training, education or hands-on experience. The purpose of this paper is carry out conceptual and empirical review on entrepreneurial competency and entrepreneurial success to provide a deeper understanding of the concepts and provide research direction to researchers most especially at this time of global inflation when small and medium businesses are finding it difficult to survive. Therefore, the paper provides a detailed review of the concepts of entrepreneurial competency and entrepreneurial success. Also, empirical review on the effect of entrepreneurial competency on entrepreneurial success and four measures of success namely profitability, sales growth, customer satisfaction and competitiveness are presented in this paper. The paper recommends that researchers should focus more attention on studying various dimensions of entrepreneurial competency to examine their effects on both financial and non financial measures of entrepreneurial success.

The capabilities of corn-silk doped molecularly imprinted polymer (CSDMIP) and its non-imprinted counterpart (CSDNIP), prepared using  styrene as a functional monomer, in the adsorption of crystal violet (CV) dye were tested. The polymers were characterized by X-ray  diffractometry (XRD), Fourier-transform infrared spectroscopy (FTIR), Thermogravimetry analysis (TGA) and scanning electron  microscopy (SEM). The adsorbent potency in the dye removal was investigated by varying the effect of pH, time, dye concentration and temperature. A good removal efficiency of CV in the range of 95-99% was achieved for the imprinted polymer. 2 Correlation coefficient R  value was the criterion in order to select the best kinetic and isothermal models. Pseudo-second-order model displayed a better fitness  for kinetics data compared to the Elovich, Weber-Morris and pseudo-first order models. Likewise, Freundlich isothermal model depicted a  better fit for the adsorption 2 data for CV dye, demonstrating R values of 0.9998 and 0.9999 for both CSDMIP and CSDNIP, respectively. The adsorption process was described as spontaneous and exothermic attributable to the negative o o thermodynamic parametrical  values of DG and DH . In comparison to other selected adsorbents, CSDMIP -1 was found more efficient with Langmuir adsorption  capacity of 181.82 mgg . In addition, the CSDMIP had an interestingly high reusability potential of ˃97% up to the sixth cycle.  Computational study employed to validate the experimental analysis, gave a good result. Applicability of the developed adsorbent in real  textile wastewater gave over 83% efficiency, suggestive of a promising adsorbent for the sequestration of CV from solution.
Romska pozycjonalność (positionality) – subiektywne doświadczenia Romów a dyskurs akademicki
Authors: Mirga-Kruszelnicka Anna
Published: August 2024

The field commonly known as Romani Studies has been monopolized for decades almost entirely by non-Romani researchers and, consequently, has been written from an outsider’s perspective, from the standpoint of the majority culture. However, there is currently a significant increase in the number of Romani academics who critically assess the body of research on the Roma and simultaneously lay the foundations of so-called Critical Romani Studies. This situation inevitably leads to questioning the relationship between the researcher and the researched and negotiating the position of the Romani scholar writing from a minority perspective.
In this article, I discuss the potential of positionality theory and its added value for the development of Romani Studies. Referring to the scholarly achievements of representatives of other minorities or peripheral communities (or as Gayatri Spivak calls them – subalterns), I will present the challenges and opportunities faced by minority researchers in negotiating the multiple roles arising from their status as „outsiders within” (Collins 1986) and how they can be applied in Romani Studies. I conclude that the synthesis of life experience, academic education, and adherence to high standards in the research process, which many Romani scholars possess, constitutes an added value for the development of Romani Studies, enriching it with the necessary diversity of perspectives and voices.
Czy Bóg to Gadzio? Religijność i konwersje polskich Romów w perspektywie elastycznych epistemologii romskości
Authors: Garapich Michał P.
Published: August 2024

The article is an anthropological analysis of religious conversions among Polish Roma. Through pioneering ethnographic work among transnational Roma communities, the article takes a critical approach to contemporary analysis of religious lives of Roma in Polish scholarship. Following the relational approach of Frederik Barth, Michael Stewart and participatory ethnography of Paloma Gay y Blasco, the article proposes an ethnographically grounded interpretation of new forms of religiosity among Polish Roma emphasizing individual agency, creativity and the so called by Marco Solimene and Stefanii Pontrandolfo flexible epistemologies, through which we can better grasp overall social changes in Poland.

Klasa i tożsamość. Różnice etniczne i socjoekonomiczne wykluczenie w budowaniu wspólnoty
Authors: Tubacki Hubert Mikołaj
Published: August 2024

In the text, the author, analyzing the processes of alienation and exclusion of residents of a fragment of a gentrified neighborhood, considers what role class and race play in this process. In addition to economic and class exclusion, the key terms for the author are alienation (othering) and racialization (racialization), together they set the conceptual framework for the analysis. Based on six months of ethnographic research, the author confronts perceptions about the ghetto with the relations found inside. He describes the formation of a local identity based on shared exclusion and opposition to denunciation and cooperation with state officials. Analyzing the role of local identity juxtaposed with Polishness and Romaniness, the author shows how these imagined communities are negotiated and how their role changes depending on the contexts. Following Marianne Gullestad, the author considers the influence of strongly rhetorical terms, e.g. Gypsy, Roma, on the processes analyzed. At the same time, he recognizes secondary exclusion resulting from targeting aid programs along ethnic lines rather than on the basis of community needs. The text also presents examples of positive, partly grassroots, actions to reduce the scale of exclusion, which include the problem of inadequate redistribution to local conditions.

Published: August 2024

This article explores the changes currently underway in the field of mental health. We historically explore the metamorphoses since the second half of the 20th century regarding a new conception of mental disorders. Thus, we come back to the transformation of patient status induced by these new approaches. These new paradigms influence both the legal tool and the practices of care and research. In this way, we question this evolution in order to understand what it could tend towards in the future. Finally, to support these many changes which tend towards a balance between users and professionals, we propose to think about the conception of a mixed knowledge that can be used by both professionals and users.

Cet article explore les changements en cours dans le champ de la santé mentale. Nous explorons, d’un point de vue historique, les métamorphoses depuis la seconde moitié du XXe siècle concernant une nouvelle conception des troubles mentaux. Nous revenons sur la transformation du statut de patient induit par ces nouvelles approches. Ces nouveaux paradigmes influencent tant l’outil juridique que les pratiques de soins et de recherches. De cette manière, nous questionnons cette évolution afin de comprendre ce vers quoi elle pourrait tendre. Pour appuyer ces nombreux changements qui tendent vers un équilibre entre usagers et professionnels, nous proposons de penser la conception d’un savoir mixte qui puisse être utilisé à la fois par les professionnels et les usagers.

Periprosthetic joint infection (PJI) is common among complications of knee arthroplasty. Treatment is based on many factors in each patient individually, especially the time onset of infection whether it is acute or chronic. Two stage revision is the best method in chronic PJI case under certain circumstances. There are few patients in three years period whom diagnosed with chronic PJI after Total Knee Arthroplasty (TKA). All patients diagnosed more than three months postoperatively, confirmed by clinically sinuses on the knee, and some patients have blood test and radiological sign of infection. All treated with two stage revision which is debridement, removal all implant put articulating knee spacer in the first operation, continue with arthroplasty with constrain implant in the second operation after infection confirmly eradicated and treated by one consultant surgeon in the same hospital. All patients treated with the same method have good results which are no pain, stable knee and satisfying knee Range of motion (ROM) following different recovery time. Two-stage revision have a good success rate in chronic PJI treatment as long as the patient fulfill the treatment criteria. Keywords : TKA (total knee arthroplasty), PJI (prosthetic joint infection), two stage revision procedure
