Entrepreneurship and Organizational Resilience
Authors: Tennin Kyla L.
Published: October 2022

Economic growth is traditionally known to regard improving access to jobs for individuals and their quality of life, with greater focus on job creation during times of crises to recover from recession or heading towards recession. The COVID-19 pandemic is a prime example. As a result, within an entrepreneurial context, entrepreneurship is a solution to economic crises that threaten financial security, job creation, and growth because entrepreneurs own organizations and hire workers. Entrepreneurs and organizations help economies operate, innovate, grow, recover, and even provide employment for individuals and families. So, organizational resilience during entrepreneurship, in general for small dilemmas, but especially during unprecedented times, is necessary. Furthermore, resilience, organizational resilience, corporate governance, financial inclusion to provide entrepreneurs with capital resources to remain in business instead of dissolving during adversities, education, and strategic partnerships are needed during crises to protect businesses and gain resilience.
Lebanese Entrepreneurs' Adaptation to the Multilevel Crisis
Authors: Saleh Lina , Levy-Tadjine Thierry
Published: October 2022

During a multi-level crisis—economic, health and security—post-explosion of the Port of Beirut, Lebanese entrepreneurs are opting for changes that allow them to survive. The authors studied the experiences of 14 entrepreneurs during crises and carried out a qualitative analysis which made it possible to identify the different variables, highlighting the application of the war strategies as written by Robert Greene. The most marked variables are the date of creation of the entrepreneurial activity, the sector (nature of the activity), the availability of financial resources, the level of change, the subjective well-being, the work-life balance, and the entrepreneur's optimism regarding the development of the business in the future. These variables were reviewed through Robert Greene's strategies of war: the controlled chaos strategy, mind flexibility (management like water), the power of fire, the counterbalance strategy, fighting the present war, and the detached buddha tactic.

Authors: Korkealehto Kirsi , Leier Vera
Published: October 2022

This research presents a virtual exchange project between two tertiary institutions in New Zealand and Finland with 26 participants who were intermediate German language students. During the project, the students used a closed Facebook group to post about given topics; the posts combined video, audio, and text that adhered to multimodal meaning-making theory. The theoretical framework was task-based language teaching underpinned by the notion of engagement, social media in language learning, and telecollaboration. Language learning was viewed through a socio-cultural lens. A mixed-methods approach was used to collect data including questionnaires, interviews, and FB-logs. The qualitative data was analysed by content analysis method. The results indicate that the students perceived FB as an applicable tool for community building and they enjoyed the variation it brought to the course. Collaboration, use of communication tools, authenticity, and teachers' support fostered student engagement.

This study has examined the library and information science female undergraduates' preference for Facebook as an information-sharing tool. A survey approach was adopted using a questionnaire to collect data from 457 LIS female undergraduate students drawn from five library schools in Nigeria. The findings of the study have demonstrated that most significant factors that lead to the use of Facebook for information sharing among LIS female undergraduate students are user-friendly nature of the tool, personal gain, enjoyment, and self-efficacy while the least factors are social engagement and empathy. User-friendliness nature of Facebook has the highest correlation with the preference for Facebook as an information-sharing tool by female students followed by enjoyment while learning and empathy are the least correlated factors.
Effects of Social Network Information on Online Language Learning Performance
Authors: Al-Hasan Abrar
Published: October 2022

This study examines the value and impact of social network information on a user's language learning performance by conducting an online experiment in a peer-to-peer collaborative language learning marketplace. Social information or information about others in one's network can present a socially networked learning environment that enables learners to engage more in the learning process. Experimental research design in an online language learning marketplace was conducted. The study finds evidence that the mere visibility of social network information positively impacts a learner's learning performance. Learners that engage with social interaction perform better than those that do not. In addition, active social interaction has a stronger impact on learning performance as compared to passive social interaction. The study concludes with implications for platform developers to enable the visibility of social information and engineer the user experience to enhance interactive learning.

Published: October 2022

Social networking sites over the years have changed from a few user-based sites into a phenomena that has become a platform for a huge number of users. However, the growth and development of social networking sites have brought great concerns on parents and educational authorities with respect to potential risks that are facing the university students as they use online social networking frequently for gathering information. The use of social networking sites among the university students requires much attention with increasing number of students creating profile and feeding their personal information into the sites. The increasing activity on the sites by student community can negatively impact the normal activity of students' lives. This can also become a hindrance to the academic development as well as social engagement of students. Therefore, there is a need to study, assess, and evaluate the issues revolving the usage of social networking sites among the student community. The study shows that the distribution of respondents according to their influence of SNS. It shows both section-wise distribution and their composite scores. Also, the table shows the respective mean scores and standard deviation. It may be inferred that 77.50% of the respondents have stated that the influence of SNS are high, 18.55% of the respondents have stated that the influence of SNS is moderate, and 3.95% of the respondents have stated that the influence of SNS is low. However, the composite mean score (2.72), standard deviation (0.530) depicts that the respondents have stated that the influence of SNS is high.
Sobre ‘formação’ e trabalho pedagógico dos professores: ‘parece que o vento maneia o tempo’
Authors: Ferreira Liliana Soares
Published: October 2022

O texto tem como objetivo argumentar sobre ‘trabalho pedagógico’ e ponderar sobre a naturalização da expressão muito recorrente ‘formação de professores’. Marca-se a expressão com aspas para destacar e indicar o quanto um modo de pensar pode ser recorrentemente aplicado, naturalizando-se, e, por isso, sendo pouco questionado quanto à sua existência e aos pressupostos que lhe orientam. Não se trata de um mero substituir expressões, mas, efetivamente, propor sentidos necessários para reconstruir o modo como os professores se relacionam com o que produzem e se entendem profissionais. Os argumentos foram elaborados com base na sistematização de estudos desenvolvidos e pesquisa bibliográfica. Aqueles estudos foram o campo empírico remoto, na medida em que, deles, foram analisados as sistematizações e os registros. Do ponto de vista teórico-metodológico, aplicou-se Análise dos Movimentos de Sentidos, que incluiu o movimento dialético entre síntese-análise-síntese dos sentidos como um ‘perguntar-se sobre’, um ir e vir aos discursos. Assim, este artigo apresenta as concepções de ‘formação de professores’; segue uma abordagem sobre os professores, seu trabalho e os processos de ‘formação’; apresenta-se, ainda, o trabalho dos professores como prática e como práxis. Por fim, colocando em relevo o trabalho pedagógico, argumenta-se que é práxico, superando a prática, como elemento da ‘formação de professores’.

Authors: Klein Ana Maria , Oliveira Flaviana de Freitas , Costa Juliana dos Santos , Santos Paula Toledo Lara dos
Published: October 2022

O artigo apresenta a análise documental de um corpus constituído por 95 portfólios elaborados em uma disciplina de Educação em Direitos Humanos (EDH) ofertada em um programa de pós-graduação stricto sensu. Portfólios foram utilizados como estratégia metodológica para abordar conteúdos relacionados aos Direitos Humanos (DH), numa perspectiva interdisciplinar e transversal, priorizando a percepção destes direitos a partir da realidade. No início da disciplina, durante 5 semanas consecutivas, os estudantes elaboraram portfólios atendendo à proposta de trazerem algum Direito Humano com o qual se depararam por meio do veículo por eles escolhido, por exemplo: notícias, músicas, filmes, imagens, dentre outros.  Trata-se de uma pesquisa aplicada com abordagem qualitativa, desenvolvida por meio de análise documental, cujos objetivos foram: analisar os DH presentes nos portfólios; levantar os veículos utilizados para identificar os DH. A análise do material foi realizada por meio da categorização dos Direitos Humanos e dos veículos.  Os resultados demonstram que a maior parte dos portfólios analisados, 65%, referem-se aos direitos civis e políticos. Em 24% dos portfólios estão os direitos econômicos, sociais e culturais (DESC). O terceiro grupo, com 11% de portfólios, destaca direitos difusos e coletivos, que se caracterizam por se destinarem a um grupo, categoria ou conjunto específico de pessoas que tem algum tipo de vínculo, algo em comum. O veículo mais presente dentre os trabalhos analisados foram os que divulgam notícias, com 44% de portfólios; em seguida, os veículos relacionados à arte como imagens, músicas, quadrinhos e poemas com 41% dos portfólios. O uso de portfólios favoreceu a percepção e a discussão dos Direitos Humanos de maneira contextualizada, indicando também os diferentes veículos que podem contribuir para a abordagem destes conteúdos em sala de aula.

Authors: Totti Marcelo Augusto
Published: October 2022

O objetivo deste artigo é apresentar os resultados da pesquisa realizada em uma escola da periferia de Marília. Partindo do pressuposto de que o processo cultural deve ser observado dentro de uma visão micro e macrossociológica, tendo como base as análises de Paul Willis, o qual destaca que os processos culturais podem ser absorvidos e reelaborados de uma forma dialética, remodelando e criando um processo de resistência cultural a partir das escolhas feitas pela própria classe operária em questão, que o autor denominou de uma contracultura escolar. A partir dessa referência, observamos a necessidade do conhecimento da realidade escolar para aproximar os conhecimentos científicos ao horizonte cultural dos estudantes através de uma transposição didática. Assim, a partir de uma sequência pedagógica que tinha por premissa conhecer a realidade dos estudantes foi possível adaptar os conhecimentos sociológicos à realidade desses estudantes, através de técnicas de ensino e produção de material didático possibilitando uma maior aquisição dos conteúdos da disciplina de sociologia por parte dos estudantes, constituindo novas formas de ensino-aprendizagem e construindo uma formação de professores na área de sociologia mais sólida.

Authors: Wali Murugesh , Kumar U. S. Dinesh , Shetty Shyam Prasad , Sujay K. R.
Published: October 2022

Ketamine, a phencyclidine derivative has got a unique set of actions among anaesthetic drugs causing dissociative anaesthesia. It has been mainly used for induction of anaesthesia and intraoperative analgesia. Recently, there has been a resurge in ketamine owing to its efficacy as an infusion for perioperative and postoperative analgesia. The aim of this study was to compare intravenous infusion of ketamine with thoracic epidural bupivacaine-fentanyl infusion in managing postoperative analgesia in patients undergoing thoracotomy.
Methods: 62 patients posted for elective thoracotomy for decortication were randomised into two groups. Patients in group K (n=32) received 0.5 mg/kg bolus followed by an infusion of 2 mcg/kg/min infusion of ketamine and patients in group E (n=30) received thoracic epidural bupivacaine fentanyl infusion for 48 hrs post-surgery. Numerical rating scale (NRS) pain scores were noted at rest and on cough every 4 hrs till 48 hrs post-surgery. Ramsay sedation scores, incidence of side effects, and dose of rescue analgesics were also noted.
Result: NRS scores were significantly lower in Group K compared to group E, both at rest and on cough (p=0.002 and p=0.001). There was no difference in the levels of sedations or the need for rescue analgesic of paracetamol (p=0.356) though there was a difference between need for second rescue analgesic of tramadol (p=0.034) in group E.
Conclusion: Low dose ketamine infusion provides better postoperative analgesia post thoracotomy compared to thoracic epidural infusion.

Authors: Dhondu Harsha , Talapatra Arjun , Varghese Nita
Published: October 2022

Complications associated with central venous catheters (CVC) can be early or delayed, and among them, hydrothorax is a rare one. Inappropriate initial positioning of the catheter, repeated changes in positioning and movement of the patient, and improper vigilance may be the causative factors. We describe a 47-year-old man with delayed right-sided hydrothorax after right-sided subclavian central line insertion. He was posted for anterior communicating artery aneurysmal clipping when the right-sided subclavian CVC was placed. His intraoperative and postoperative periods were uneventful. However, on postoperative day two, the patient developed labored breathing with desaturation to 76% of room air, with hypotension and tachycardia. An urgent chest x-ray was ordered and showed features suggestive of right-sided hydrothorax, which improved after right-sided intercostal drainage. This case report highlights the presentation of a rare complication of CVC and its recognition in patients with diminished consciousness. It also emphasizes the optimum site of positioning the CVC tip and the need for increased vigilance by healthcare providers in ordering routine chest x-rays, aspirating from all catheter ports prior to administering substances through them.

Authors: Ranamuni Roshangani Rasavindika , Dassanayake Vihara
Published: October 2022

A 19-year-old girl with haemolytic uraemic syndrome (HUS) and hypertension underwent a diseased donor kidney transplantation. She developed two episodes of generalised tonic-clonic convulsions on the second postoperative day. Posterior reversible encephalopathy syndrome (PRES) was diagnosed based on the history and imaging. PRES was likely as it is associated with factors which co-exist with chronic kidney disease. Perioperative MMF, tacrolimus and prednisolone were prescribed by the nephrologist. Her serum tacrolimus level was normal at the time of convulsions. Other causes of seizures such as hypoglycaemia, electrolyte abnormalities, infection and intracranial haemorrhages were excluded. Elevated blood pressure associated with severe visual impairment was noted during the second episode of convulsions. Clinical diagnosis was confirmed by magnetic resonance imaging (MRI). She had a complete recovery without residual neurological deficits. Her blood pressure was controlled at the time of discharge and she had a well-functioning graft. Timely detection and institution of early treatment led to a successful recovery.

Authors: Pormasoumi Hosien , Rostami Daryoush , Jamebozorgi Khosro , Mirshekarpour Hosein , Heshmatnia Jalal
Published: October 2022

Iran has one of the highest death rates from COVID-19 among Middle Eastern countries. In addition to having a better disease registration system compared to neighboring countries, many factors including economic conditions, have played an important role in increasing the number of mortality rate. This is while that during the Corona pandemic, Iran has been undergo severe sanctions by the United States, that has faced this country with a severe economic crisis. Considering the role of sanction on the country's health management in our study, we examined Iran's management plans against the Corona pandemic and the effect of sanctions on it. Quarantine and corona restrictions, on the one hand, and international sanctions, on the other hand, have put double pressure on the Iranian government. Although drugs and basic medical equipment are exempted from economic sanctions, direct and indirect effects of the sanctions have limited Iran's banking system and created widespread restrictions in the fields of trade, production, and investment. Fortunately, despite the sanctions, many hospitals had an appropriate performance in line with the health promotion program. It is obvious that economic sanctions have severe and harmful effects on public health and have led to poor health consequences in Iran, but attention to planning, standards and improving the quality of the hospital is an important issue in Corona management. Despite multiple mutations, this virus is likely to face with a more dangerous virus in the world future. Now, it is time to take appropriate management measures to remove these sanctions by relying on international solutions and interactions.
Meaning Making Among Professional Master's Athletic Training Students
Authors: Myers Sarah Lynn , Taylor Kari B. , Singe Stephanie Mazerolle , Barrett Jessica L.
Published: October 2022

Context

New approaches to education and pedagogy are needed in athletic training education to better support developmental benchmarks that cultivate skills for lifelong learning.

Objective

Explore and understand students' perceptions of their education and how those perceptions support their development toward self-authorship through the complexity of their meaning making.

Design

Qualitative, grounded theory.

Setting

Division I Commission on Accreditation of Athletic Training Education athletic training programs.

Patients or Other Participants

Twelve participants (9 female, 3 male; age = 24 ± 2 years) in their second year of athletic training education were recruited for the study. Of the 12 participants, 11 were engaged in an immersive clinical experience.

Data Collection and Analysis

Participants engaged in a semistructured video conference interview. Data were analyzed using grounded theory approach to understand the complexity of students' ways of making meaning cognitively, intrapersonally, and interpersonally. Data saturation, peer review, member checks, and theoretical triangulation were used to establish credibility.

Results

Participants exhibited meaning making in 2 distinct ways: (1) external guidance and (2) movement toward internal guidance. The categories were further broken down by theme. Placing responsibility for knowledge on authorities, need for step-by-step guidance, and seeking approval marked the themes of external guidance. Building confidence and role identity development marked themes of movement toward internal guidance.

Conclusions

Participants who were reliant on external guidance required external authorities for knowledge acquisition and learning. Some participants demonstrated deeper meaning making when discussing their experiences with clinical education.
Addressing the Habitual Practice Issue: The Role of Unlearning in Promoting Evidence-Based Practice and Lifelong Learning
Authors: Pike Lacy Alicia M. , Lam Kenneth C. , Welch Bacon Cailee E.
Published: October 2022

Context

Habits play a large role in health care professionals' behaviors. Although habitual practice patterns limit cognitive overload, routinized approaches can compromise the provision of quality and contemporary patient care. To address the issue of habit, unlearning has been suggested across health care fields but remains a relatively new concept in athletic training.

Objectives

This commentary aims to (1) describe the concept of unlearning, including barriers to and facilitators of this process, (2) discuss the steps in the unlearning process via a published unlearning framework, (3) highlight the role of unlearning on improving evidence-based practice and lifelong learning among clinicians, and (4) apply a context-specific example to the unlearning framework to highlight the role of unlearning on improving patient care.

Background

Although evidence-based practice can result in improved quality of care, literature suggests that routine uptake and incorporation of evidence into patient care is limited. The reason for this gap is likely multifactorial, but may, in part, be related to the need for unlearning.

Synthesis

Rapid changes in health care delivery require medical professionals to adapt their practice behaviors to maintain competence over time. Unlearning facilitates behavior change because it involves an intentional act of moving away from knowledge and skills that are no longer effective. As such, unlearning may also improve evidence-based practice efforts.

Recommendation(s)

To abide by changing recommendations, clinicians must unlearn outdated behaviors first before replacing them with evidence-based techniques. As new knowledge is acquired, it is important to reflect on its applicability to one's practice setting and identify what, if any, outdated practices the new knowledge could replace.

Conclusion(s)

Self-reflection is essential for successful unlearning to occur. Identifying the overall effectiveness of various practice behaviors and acting on areas of improvement can help ensure the care provided to patients is evidence-based while simultaneously optimizing patient outcomes.
Integration and Outcomes of a Hybrid Simulation for Simple Laceration Suturing
Authors: Winkelmann Zachary K. , Neil Elizabeth R. , Eberman Lindsey E.
Published: October 2022

Context

Emergency and immediate care skills are often difficult to practice in real time during clinical education. One immediate care skill requiring advanced training that may not be implemented during clinical education is wound closure via suturing. Simple laceration management with sutures can be advantageous skill for athletic training students to learn and practice; however, deliberate practice with feedback in a realistic manner is necessitated.

Objective

To describe the use of hybrid simulation to practice suturing in professional and postprofessional athletic training programs.

Background

The practice of immediate and emergency skills is predominately classroom based and removes the patient experience. Simulation-based learning has provided athletic training educators an opportunity for skill practice with patient simulators and standardized patients to fill the gap.

Description

The hybrid simulation incorporates the use of a standardized live patient actor with an attached part-task–training simulated arm for suturing in a safe and realistic manner.

Clinical Advantage(s)

Incorporating a hybrid simulation encounter for practice of suturing skills requires multitasking and delivery of patient-centered care and promotes proper skill execution while receiving questions and direct feedback from the standardized patient.

Conclusion(s)

Suturing should be taught and assessed in a tiered format using part-task trainers such as pig skin and artificial skin pads. After skill development, a hybrid simulation as a summative assessment allows for the educator to evaluate the learners' interpersonal communication and technical skills in a safe manner.

Authors: Revathi T. N. , Aithal Sowmya S.
Published: October 2022

Background:

Dystrophic nails represent an alteration in nail morphology that can occur due to various disorders. Although KOH is used commonly in the diagnosis, the sensitivity and specificity of KOH are less. Chicago sky blue (CSB) stain when used with KOH provides color contrast, to aid the detection of fungal elements, and is a simple and inexpensive method.

Materials and Methods:

Nail scrapings from the surface and subungual areas and nail clippings were examined with 40% KOH, CSB stain, and also subjected to fungal culture.

Results:

The detection rate of fungal elements in dystrophic nails in our hospital-based study was 46.5%. The sensitivity of KOH was 36.36% and CSB staining was 66.6% using fungal culture as a gold standard.

Conclusion:

CSB stain serves as a useful, simple, and rapid method for detecting the presence of fungal elements.
Clinico-dermoscopic Diagnosis of Skin Cancers in Skin of Color
Authors: Bhat Yasmeen Jabeen , Dar Uzair Khursheed , Zeerak Sumaya
Published: October 2022

The diagnosis of skin cancers in the past was based on a visual inspection of the lesion, with the confirmation of doubtful lesions by a histopathological examination of the skin biopsy. Clinical examination alone, as the basis for undergoing skin biopsy of the lesion, may result in misdiagnosis in some cases, resulting in the mismanagement of lesions with malignant potential or unnecessary evaluation when a doubtful lesion is suspected. The development of dermoscopy as a noninvasive in vivo tool in the diagnosis of skin lesions has the potential to improve diagnosis as well as aid in early and more accurate identification of skin cancers as compared with the unaided eye. Dermoscopy has also gained increased interest in the management of skin cancers by regular dermoscopic examination on follow-ups to decide further course of management. When detected early, skin cancers can be cured by simple procedures or techniques; however, as the disease advances, it becomes more difficult to treat. This article reviews the role of dermoscopy in the diagnosis of commonly encountered primary skin cancers in skin of color.

Published: October 2022

In order to address issues of limited resources and contamination by fertilizers, nutrient solutions may be reused in hydroponics as an alternative to their disposal in the environment. This work evaluated the feasibility of nutrient replacement for the nutrient solutions reused during lettuce hydroponic cultivation. The experiment was carried out in an agricultural greenhouse in an NFT hydroponic system using the “Milena” lettuce cultivar. The experiment was divided into two stages: 1) monitoring and data collection and proposition of nutrient replacement management; and 2) validation of the proposed replacement management. Monitoring the consumption of the crop's nutritional solution in the first stage served as the basis for the proposed nutritional replacement management. Management was validated in the second stage through the evaluation of fresh and dry mass, crop nutritional status, and the amount of the fertilizer applied in the treatments: T1 - nutrient replacement with nutrient solution reuse; and T2 - nutrient replacement without nutrient solution reuse. The fresh and dry mass data and the amount of nutrients absorbed by the plants were submitted to the t-test at 5% probability, showing no significant difference between the treatments, making it possible to conclude that the nutrient solution reuse provided nutrient replacement during the lettuce crop cultivation.

Keywords: hydroponic system, Lactuca sativa L., macronutrient rational use.

Saccharomyces cerevisiae biomass was activated chemically, and its ibuprofen (IBP) biosorption capabilities were assessed regarding IBP removal from an aqueous solution. The effects of pH (2-10), contact time (0-90 min), IBP concentration (5-35 mg L-1), and temperature (20, 30, 40°C) were evaluated in batch studies. Higher removal rates of IBP were found at pH 2.0. The pseudo-second-order kinetic model best described the experimental data. Both the Langmuir and Freundlich isotherm models described the equilibrium data satisfactorily. The maximum biosorption capacity for IBP onto chemically activated Saccharomyces cerevisiae biomass (CA-YB) was estimated at 13.39 mg g-1 at 40°C. The activation energy calculated by the Dubinin-Radushkevich isotherm model was 9.129 kJ mol-1, indicating that a chemical process mediated the biosorption of IBP onto CA-YB. According to thermodynamic studies, IBP biosorption is spontaneous and endothermic. FTIR analysis revealed that the carboxyl, hydroxyl, phosphoryl, and amino groups were involved in the biosorption process of IBP. These findings indicated that CA-YB could be an alternative biosorbent for IBP removal from aqueous media.

Keywords: isotherms, kinetic, microbial biomass, pharmaceutical drugs, thermodynamic study.

Published: October 2022

This study compares physical and chemical parameters of water samples collected in a marginal lake (Castelo Bay) in the Paraguay River Basin in southern Pantanal during a significant natural phenomenon of hypoxia, locally called decoada, and shortly after it. Limnological parameters were analyzed from four sampling sites along the bay. Comparisons of the physical and chemical parameters between decoada and post-decoada periods were performed by Student’s t-test, principal component analysis and multivariate permutational analysis of variance (permanova). During the period of the decoada, there was a significant reduction in mean values of water transparency and concentrations of dissolved oxygen, sodium and nitrite compared to the post-decoada period. On the other hand, water temperature and conductivity, and concentrations of orthophosphate, total nitrogen and total iron have all had higher values during the decoada period. An effect of connectivity between lake and river was found to generate a gradient of water characteristics at Castelo Bay. The limnological characteristics that differed the most between decoada and post-decoada periods are those associated with the reduction of dissolved oxygen that could cause natural death of fish and the increase in nutrients during the decoada, yet they vary on temporal and spatial scales.

Published: October 2022

To enhance the microstructural and mechanical properties of Reduced Activation and Ferritic-Martensitic (RAFM) steel thermo mechanical treatment (TMT) was performed on as received Normalised and Tempered steel (N+T). The RAFM with 9Cr-1W-0.06Ta major alloying elements steel was used in the study in N+T and TMT conditions. The refinement in microstructure and precipitates was observed in TMT steel in comparison to N+T steel. There is a drastic improvement in mechanical properties such as hardness, tensile properties are observed without losing the ductility. The creep deformation behaviour of thermo-mechanical treated steel and N+T steel were studied at different stress levels at 823 K. The comparative creep rupture and strain properties were studied, and various creep deformation regimes were also analysed for both the conditions of steel. The rate of exhaustion of primary creep (r), minimum creep rate and time spent in primary and tertiary creep regime, rate of acceleration of tertiary creep and time to reach the onset of tertiary creep. Microstructural studies on Optical and Scanning electron microscopy and transmission electron microscopy results were correlated with the mechanical properties of steels. On a whole, a comparative investigation was performed on various reasons for drastic improvement in tensile and creep rupture properties of TMT steel than the steel in N+T steel and necessary microstructural investigation support is considered.

Engineering, automotive and consumer products include several components, which are connected to each other for their operational purpose and thus form assemblies. Sensors, which are usually formed by assembling several components with each other, have become an integral part of the systems around the world. The components forming these assemblies are made up of various materials like polymers, metals, metal alloys, composites etc. They are connected to each other and then are usually over molded by a thermosetting material which firmly holds these components so that no relative motion is possible among them. Testing was done on a similar speed sensor assembly. When the assembly was mounted in the test rig and step wise temperature variations were applied on it to represent operational loads, failure observed in the assembly in the form of multiple cracks at different locations. This paper investigates the reasons for failure and provides optimal material solution to avert the failure. Initial testing was followed by Finite Element Analysis, which verified these multiple failure locations. By carefully observing the FE analysis results, it was identified that the reason for failure was the substantial difference between the expansion of certain components, particularly at high temperatures. With the extensive research in the area of thermosetting and thermoplastic materials, and with the subsequent parametric study with the help of FE analysis, the optimal material combination was found which in turn led to avert the failure. Subsequent testing with the above identified optimal material combination validated the results given by FE analysis and no further failure was observed. This work enabled in establishing efficient product development process by reducing multiple loops of testing.

La production rizicole (Oryza sativa L.) en Côte d’Ivoire est menacée par plusieurs contraintes biotiques particulièrement les maladies dont l’helminthosporiose est l’une des plus préjudiciables. Cette maladie est causée par le champignon Bipolaris oryzae, très rependue en riziculture pluviale. Dans le cadre de la mise en place de moyens de lutte contre cette phytomycose, une étude a été menée avec une dizaine de génotypes de riz. L’essai a été conduit en milieu réel, sous pression naturelle d’helminthosporiose selon un dispositif expérimental en split plot à Gbombélo dans la sous-préfecture de Biankouma. Au cours de cette expérimentation, les notes de sévérité attribuées aux génotypes ont été différentes d’un génotype à un autre. Les résultats obtenus sur les paramètres agronomiques ont montré non seulement une réduction du nombre de talles et du poids de mille grains allant de 4,9 % à 15,97 % et 12,8 % à 38,6 % respectivement sous l’action du champignon. Par ailleurs, les pertes de rendements induites par la maladie sur les génotypes ont varié également de 20,35 % à 56,49 %. Globalement, l’essai a enregistré une perte moyenne de rendement estimée à, l’helminthosporiose a causé une perte moyenne de rendement de 34,37 %. De tous les génotypes évalués, les génotypes ARCC3Fa3L10P1-1-B-1 et WAB 891-SG12 ont affiché une bonne tolérance vis-à-vis du champignon en tenant compte de la sévérité, des composantes de rendements du riz et de l’incidence de la maladie. L’adoption des génotypes ARCC3Fa3L10P1-1-B-1 et WAB 891-SG12 s’avère prometteur dans un programme de lutte génétique contre l’helminthosporiose du riz en Côte d’Ivoire.
Assessment of citrus diversity in Ghana

Citrus is among the plant germplasm conserved at the CSIR - Plant Genetic Resources Research Institute (CSIR - PGRRI), Bunso in Ghana; however, due to lack of information on the specific traits of this germplasm at the Institute, the potential diversity within the collection is not yet fully exploited. The objective of this study was to evaluate the morphological diversity among the citrus accessions under conservation at the field genebank of the CSIR - PGRRI, Bunso, Eastern region of Ghana. The various accessions were raised on rough lemon rootstocks, planted using the augmented design. The citrus accessions evaluated include different citrus types suitable for different purposes, such as Flying Dragon for rootstock, Sweet Lime for medicine and Mediterranean Sweet for fruit drink. Late Valencia and Mediterranean Sweet were used as checks. Planting was done at 8 m by 8 m. Apart from watering immediately after planting, the plants grew under natural condition without irrigation. Variability was revealed by all the traits studied, including scion trunk surface, tree shape, tree growth habit and branch angle, based on IPGRI descriptors for citrus. The resulting phylogenic tree clustered the citrus accessions mainly based on known genetic relationships, using the clustering away of citrons from mandarins as an example. Although the morphological traits used in the characterisation were not sophisticated, they were useful in discriminating among the accessions. Based on this study, the citrus genebank at CSIR - PGRRI, Bunso, Eastern region of Ghana contains 44 morphologically distinct accessions. The information generated in this study is important for guiding conservation and utilisation decisions geared towards the improvement of the citrus sub-sector in the country.
