Published: June 2022

Objetivo: O objetivo geral foi identificar os antecedentes atitudinais de capacidades dinâmicas. Para tal, foi adotado o método baseado na grounded theory.
Design / metodologia / abordagem: Como estratégias para coleta de dados, foram realizadas entrevistas de história oral de vida temática e entrevistas em profundidade. Foram adotados o método das comparações constantes e os processos de codificação aberta, axial e seletiva.
Resultados: Foi possível concluir, a partir da teoria substantiva que emergiu do campo de pesquisa, que as capacidades individuais fundamentaram a atitude intraempreendedora dos gestores de projetos de inovação. Essas capacidades individuais se associaram às capacidades organizacionais de percepção (autoconhecimento, autonomia, avaliação emocional, detalhismo e iniciativa), de apreensão (perspectiva positiva, abstração, análise crítica, controle emocional, criatividade, satisfação com aprendizagem e visão estratégica) e de reconfiguração (argumentação, autoconfiança, comunicação, disciplina, empatia, escuta ativa, flexibilidade, lidar com pressão, resistência a frustrações e visão sistêmica). Esta análise agregada revelou elementos cognitivos e emocionais emergentes, que romperam com os aspectos rotineiros do gerenciamento de projetos, consubstanciando a atitude intraempreendedora dos gestores participantes deste estudo.
Originalidade / valor: A principal contribuição do estudo foi a identificação de capacidades individuais e de comportamentos coletivos que funcionam como gatilhos atitudinais das capacidades organizacionais de percepção, apreensão e reconfiguração de recursos pró-inovação. Potencialmente, essa contribuição pode ser usada para a condução de processos de recrutamento/seleção e capacitação de gestores de projetos de inovação.

Published: June 2022

Objetivo: A sociedade pós-moderna tem apresentado grandes transformações e desafios no que concerne aos âmbitos político, econômico, tecnológico e social. A modernidade líquida impacta diretamente nas formas de relacionamento interpessoal, que têm se modificado por meio de novas tecnologias, que como uma grande vitrine social, reconfiguram relações sociais. Portanto, este artigo tem por objetivo apresentar as principais características dos perfis de usuários de aplicativos de namoro, buscando responder como estes usuários podem ser diferenciados e quais variáveis são relevantes para identificá-los.
Abordagem: Foi realizada uma survey, aplicada online, tendo como base a escala de modelagem de Ranzini e Lutz (2017) construída a partir de variáveis demográficas, psicológicas, motivacionais e de autoapresentação. Foram coletados 318 questionários e, por meio do software SPSS, realizaram-se análises descritivas, cluster e discriminante.
Resultados: Os resultados demonstraram a diferenciação entre perfis de quatro tipos de usuários de aplicativos de namoro: “Humano Líquido”, “A solitária”, “O pegador” e “A empoderada”, perfis que possuem comportamentos heterogêneos, moldados majoritariamente por questões de gênero, por questões psicológicas (solidão, autoestima e narcisismo) e motivos relacionados a sexo e entretenimento.
Limitações: Como limitações desta pesquisa podemos indicar a dificuldade em garantir a ausência de erros no que tange à veracidade das respostas, visto que não foi realizada uma abordagem direta, e os questionamentos envolveram pessoalidade e autorreflexão.
Valor: Este estudo reafirma argumentos já discutidos por outros autores sobre como as tecnologias emergentes estão mudando a forma como os relacionamentos interpessoais acontecem, mas avança academicamente no sentido de sistematizar quatro perfis de usuários de aplicativos de namoro, bem como seus usos e finalidades sociais.

Published: June 2022

BACKGROUND

Globally antimicrobial resistance is rising, and the Indian scenario is also similar to antimicrobial awareness. The study literature on awareness regarding antimicrobial resistance in public is less in quantity. This study was designed to determine the awareness of antimicrobial resistance and appropriate antimicrobial use among health care professionals and laypersons.

METHODS

This cross-sectional study was performed at a rural tertiary care hospital in Central India and included junior residents, interns and nurses, patients, and their relatives. Survey tool and data questionnaire were provided to participants in English and Marathi.

RESULTS

Total 384 people were enrolled as study participants. Health care professionals have more ideas than laypersons regarding antimicrobial use and antimicrobial resistance. Comparison of knowledge of antimicrobial resistance among hospital staff, patients and their relatives was done. The quantitative measurement of awareness of antimicrobial resistance took place with the help of this study. We were able to find out the prevalence of awareness of antimicrobial use and antimicrobial resistance.

CONCLUSIONS

This study showed a comparison between study participants for knowledge about antimicrobial resistance and antimicrobial use regarding factors like education, hand hygiene, income and those working in fields like agriculture, hospital, etc. There is a need to frame policies to prevent excessive use of antimicrobials and increase awareness about the knowledge of antimicrobial resistance in common people. If the knowledge of infection prevention and control (IPC) is well-known to everyone, the antimicrobial resistance will not be left for the treatment.
Comparative Study of DIPSI and WHO (2018) Criteria for Diagnosis of Gestational Diabetes Mellitus
Authors: Savita Bharat Konin  , Shweta Navnath Ghadge
Published: June 2022

BACKGROUND

Gestational diabetes mellitus is defined as carbohydrate intolerance with onset/recognition during pregnancy. There is an increase in incidence worldwide with a range of 0.4 - 10 %. Gestational Diabetes is often asymptomatic and associated with increased foetal and neonatal morbidity and mortality. Over the years there have been many controversies regarding the best screening and diagnostic test for GDM. The testing for GDM by appropriate method at the earliest detects women who need treatment with either diet alone or a combination of diet with insulin therapy. This helps in the prevention of maternal morbidity and mortality. Hence, an appropriate screening test for GDM has been much emphasized. This study was done to compare the non-fasting diabetes in pregnancy study group of India (DIPSI) criteria with the fasting state of the WHO 2018 for the diagnosis of GDM in our hospital setting.

METHODS

With this background, we conducted a single centric, prospective, observational study in our tertiary care hospital, after obtaining permission from the Institutional Ethics Committee. In this study, we enrolled 200 patients attending obstetric OPD in Basaveshwar teaching and general hospital and Sangameshwar hospital attached to Mahadevappa Rampure Medical College, Kalaburagi with gestational age 24 – 28 weeks as per the inclusion and exclusion criteria. All participants were then subjected to screening and diagnostic tests as per DIPSI and WHO 2018 criteria.

RESULTS

Prevalence of GDM was 12.5 % in WHO 2018 group when compared to 10.5 % in the DIPSI group. The specificity of the DIPSI method in detecting GDM was 98 %. The highest incidence of GDM was observed in the age group of 26-30 yrs. Incidence of the highest prevalence of GDM was observed with BMI > 25 kg/m2. We studied the co-relation between GDM with DIPSI and WHO 2018. True positive 16, False Negatives 9, True Negatives 179, False Positive 05.

CONCLUSIONS

Screening with DIPSI has 98 % specificity compared. DIPSI being a one-step procedure offers both a screening and diagnostic test for GDM. It avoids the need for multiple hospital visits, and multiple blood samples.
Contact Tracing during COVID-19 - A Systemic Public Health Failure
Authors: Rabiah Asif  , Azhar Hussain
Published: June 2022

Coronavirus-19 (COVID-19) created many challenges for public health agencies and healthcare services. As a virus that created immense fear of the unknown, researchers and scientists scrambled to come up with solutions to prevent the spread and rate of infection. As previously used in combating infectious diseases, contact tracing was introduced to help decrease the rapidly increasing cases. Although contact tracing is a relatively old idea, it is still a critical part of the non-pharmaceutical interventions needed to fight such an infectious virus. However, it had to be tailored to fit this new rapidly increasing virus. This paper examines the disparities, insufficient infrastructure, and lack of proper testing and reporting during the pandemic, all of which are systemic failures of public health. These systemic failures have an impact on the effectiveness of contact tracing. All barriers will be presented with potential solutions for not only this pandemic, but for any future situations as well.
Role of Pin Hole in Rapid Recognition of Refractive Error as Cause of Diminished Vision
Authors: Chaudhury Pranati , Singh Partha
Published: June 2022

BACKGROUND A tertiary healthcare set up receives an increasing load of patients with complaints of diminished vision on a daily basis. It can be quite cumbersome for conducting automated refractometry in each of them, on the suspicion of refractive error being the cause of vision loss. Few studies have shown a simple visual acuity comparison of individual eyes with and without pin-hole can determine if the patient has significant refractive error. There are minimal studies done to determine the reliability of such use of pin-hole, and even less of such studies are done in our country. The purpose of this research was to calculate the sensitivity and specificity of significant visual acuity change on using pin-hole in identifying refractive errors. METHODS Patients were selected in the age group of 15 years to 55 years with chief complaints of blurred / diminished / low vision. Patients with known history of diabetes, hypertension, trauma to eyes, and neurological/psychological complications were excluded from the study. Log MAR chart was used to measure the visual acuity in the selected subjects. Visual acuity was recorded for individual eye in each patient; first without, and then with pin-hole. An improvement in vision by at least one Log MAR scale was taken into consideration. Such patients were then subjected to autorefractometry without use of any cycloplegic drugs. A spherical refractive value of ± 1.00 D was considered significant. RESULTS Pin-hole testing has a sensitivity of 94.17 percent (95 % CI: 92.61 to 95.48) and specificity of 89.95 percent (95 % CI: 84.75 to 93.84) when compared with autorefractometry finding for identification of refractive errors (p < 0.0001). The test has an accuracy level of 93.55 per cent (95 % CI: 92.06 to 94.83). CONCLUSIONS The accuracy of pin-hole vision comparison with plain sight in diagnosing refractive errors as the cause of vision loss is reliable enough for it to be used in prompt identification of such cases.

Published: June 2022

BACKGROUND Monkeys are responsible for 2-21% of all animal bite injuries. Monkey bites are second only to the dog bites as represented in India. Control of animal rabies is central to the prevention of human disease. Thus, prophylaxis (for domestic animals and selected humans) and PET remain essential to the prevention of clinical rabies. METHODS Patients presenting to the outpatient and emergency department with the complaint of monkey bite were enrolled in the study. All particulars of patients, history and examination findings were recorded in the clinical proforma after taking proper informed consent. Wounds were categorized based on WHO guide to postexposure prophylaxis. Local treatment consisted of two parts: first aid and wound management. ARV was administered in category II and III exposures in accordance to the intradermal schedule. Data was analysed for clinical information such as age, sex, socioeconomic status, timing & site of bite, categories of contact and treatment given. RESULTS In our study of 68 patients, 24 (35.3%) were males and 44 (64.7%) were females. Majority of the patients belonged to the age group of 11-40 years in both male (n=20; 83.33%) and female (n=34; 77.27%) patients. Mean age group of patients in the study was 28.29 years. This generally reflects the greater exposure of young adults to the monkeys. Based on modified Kuppuswamy scale, most patients belonged to the class III (n=36; 52.9%) followed by class IV (n=16; 23.5%). All the patients sustaining bites from monkeys were vaccinated. Majority of the bites involved the lower extremities (n=31; 45.6%) followed by upper extremities (n=27; 39.7%). Based on WHO guidelines for wound categories, most patients belonged to category II (n=49; 72.1%) followed by category III (n=19; 27.9%). CONCLUSIONS In our study, we found that majority of patients sustaining monkey bites were young adults and belonged to lower middle & upper lower class. There was no difference with respect to gender. Most common sites of monkey bite were upper & lower extremities and belonged to WHO category II. No cases of rabies were observed in our study.

Layer recurrent neural network-based diagnosis of Parkinson’s disease using voice features
Authors: Senturk Zehra Karapinar
Published: June 2022

Parkinson’s disease (PD), a slow-progressing neurological disease, affects a large percentage of the world’s elderly population, and this population is expected to grow over the next decade. As a result, early detection is crucial for community health and the future of the globe in order to take proper safeguards and have a less arduous treatment procedure. Recent research has begun to focus on the motor system deficits caused by PD. Because practically most of the PD patients suffer from voice abnormalities, researchers working on automated diagnostic systems investigate vocal impairments. In this paper, we undertake extensive experiments with features extracted from voice signals. We propose a layer Recurrent Neural Network (RNN) based diagnosis for PD. To prove the efficiency of the model, different network models are compared. To the best of our knowledge, several neural network topologies, namely RNN, Cascade Forward Neural Networks (CFNN), and Feed Forward Neural Networks (FFNN), are used and compared for voice-based PD detection for the first time. In addition, the impacts of data normalization and feature selection (FS) are thoroughly examined. The findings reveal that normalization increases classifier performance and Laplacian-based FS outperforms. The proposed RNN model with 300 voice features achieves 99.74% accuracy.

Published: June 2022

The loss of Mediterranean macroalgal populations dominated by Cystoseira sensu lato is driven by a multitude of pressures. In the eastern Mediterranean Sea, climate change and the establishment of Lessepsian herbivore species have further intensified the ongoing decline of these canopy-forming algae. Knowledge of the reproductive phenology, embryology and growth of Cystoseira species is the first step towards successful reforestation measures. Gongolaria montagnei is one of the most common canopy-forming algal species with a wide horizontal and vertical distribution along the Greek coasts. Mature receptacles were collected from Saronikos Gulf (Aegean Sea), and germlings were cultured in mesocosms for 34 days, reaching up to 1.30 mm in length. Divisions and early developmental stages of G. montagnei are described and possible implications for future restoration efforts are discussed. A new approach to growth rate modeling, based on surface measurements of embryos and germlings is presented.

Objectives

Owing to increase in referrals for precocity observed during COVID-19 lockdown, this study was conducted to estimate the proportion of patients referred for precocity and within these, those with idiopathic central precocious puberty (iCPP) before vs. during the COVID lockdown, and to assess the differences in anthropometric and clinical characteristics among iCPP patients in the two groups.

Methods

Retrospective study conducted at a tertiary level paediatric endocrinology centre (Western India) evaluating proportion of referrals for precocity and comparing demographics, anthropometry, pubertal staging and bone age at presentation among children with iCPP divided into two groups (pre-lockdown-group 1, lockdown-group 2).

Results

During lockdown, 155 (5.1%; 146 girls) of 3,053 referrals for precocity as opposed to 59 (1.4%; 54 girls) of 4,208 before the lockdown (p<0.05) were seen; increase was higher in girls (p<0.05). Proportion of referrals for iCPP was significantly higher in the lockdown (4.4%; 136 children vs. 1%; 44 children in group 2) among both genders. Mean age at first visit was 7.8 ± 1.3 and 8.2 ± 1.2 years in groups 1 and 2, respectively. Mean height, weight, BMI and height minus mid-parental height Z scores were not significantly different between the groups. Children in group 2 had a significantly advanced mean bone age (10.7 ± 2 years) and difference in bone and chronological ages (2.5 ± 1.2 years) as compared to group-1 (9.7 ± 1.9; 1.9 ± 1.2) and a larger proportion presented in late puberty.

Conclusions

We found an increase in the referrals for precocious puberty and an increase in number of children diagnosed with iCPP during COVID lockdown.
The Troubling Relationship between Pleasure and Universality in Kant’s Impure Aesthetic Judgements
Authors: Phillips James
Published: June 2022

Kant calls judgements of adherent beauty impure aesthetic judgements because they presuppose the empirical concept of the object and are thus not determined exclusively by a feeling of pleasure. Glossed over in Kant’s account is what kind of universality these judgements have. This article argues that the subjective universality of pure aesthetic judgements and the objective universality of cognitive judgements do not merge in impure aesthetic judgements and that the tension between them reaches also into Kant’s pure aesthetic judgements with their unstable relations between the pleasure of the a priori harmony of the faculties and the empirical object named beautiful. Pleasure, which for Kant is communicable while nonetheless not being discursive, is always to some extent lost for words.
Colombia Enchanted in Memoria and Encanto
Authors: Betancourt Manuel
Published: June 2022

FQ columnist Manuel Betancourt uses the odd couple pairing of Thai auteur Apichatpong Weerasethakul’s Memoria (2021) and Walt Disney Animation Studios’ Encanto (Jared Bush and Byron Howard, 2021) to examine the cinematic representation of his home country of Colombia. Noting that his childhood cinephilia was nurtured by the foreign productions that dominated theaters, he observes that in the past few decades, bold new Colombian filmmakers have brought to the screen more varied visions of Colombia. Now with Memoria, a foreign filmmaker mines the country’s contradictions and, through his alienated and disoriented protagonist, invites viewers to embrace the unfamiliar in the world. In contrast, Encanto aches to create a kinship with Colombia by commodifying Colombian culture for mass consumption.

The article describes a new method for synthesizing quantum dots copper sulfide (CuS QDs) based on the UV-irradiation technique (photolysis method). Our process allows producing high-quality, small-size, very low cost and short time. The crystal structure of CuS QDs was characterized using X-ray diffraction (XRD) ,which confirmed the synthesized sample's hexagonal shape. The structure of the manufactured product was examined using energy-dispersive X-ray spectroscopy (EDX), and the result revealed just copper (Cu) and sulfide (S) elements, indicating that the synthetic material was pure. The morphology, optical properties, and particle size were investigated by photoluminescence spectroscopy (PL), scanning electron microscope (SEM), and transmission electron spectroscopy (TEM). The particles sizes of the CuS QDs were found to be range between 5.4 to 9.1 nm. Finally, this method successfully synthesized CuS QDs through the results.

In this work, the metal phase MoS2 was prepared by a simple one-step hydrothermal method, and it was systematically studied by XRD, Raman, SEM, TEM, and other characterization methods. In addition, the tribological behavior of M-MoS2 in water-based drilling fluids has been extensively studied with a ball-disk tribometer. In addition, the influence of applied load and speed on friction performance is also studied. The experimental results show that the introduction of M-MoS2 significantly reduces the friction and wear of the material. Among them, M-MoS2-5-water-based drilling fluid has the lowest friction coefficient (~0.11).

Objective: to estimate the incidence and identify the risk factors for incidents in patients of an intensive care center. Methods: this is a longitudinal, prospective, analytical, and exploratory study with 173 patients admitted to the intensive care unit. The incidents were categorized as clinical process/procedure, care associated infections, behavior, documentation, medication/intravenous fluids, nutrition, blood products, accidents, and medical equipment. Results: the incidence density was 134.45 incidents per 1,000 patient-days, highlighting the main categories: clinical process/procedure (71.5%) and care-related infections (15.3%). Length of stay in the intensive care unit (Risk ratio: 1.03; Confidence interval: 1.01-1.05; p=0.000) and use of central venous catheter (Risk ratio 1.02; Confidence interval: 1.00-1.04; p=0.040) were identified as risk factors. Conclusion: there was a high occurrence of incidents in the intensive care unit, especially in patients with longer hospital stay and use of central venous catheters. Contributions to practice: identifying incidents and associated risk factors will allow managers and professionals to recognize patients at higher risk and implement measures to ensure systematic and quality care to minimize the occurrence of adverse events in the institution.
Producción y uso de pellets de biomasa para la generación de energía térmica: una revisión a los modelos del proceso de gasificación
Authors: Forero Núñez Carlos Andrés , Guerrero Fajardo Carlos Alberto , Sierra Vargas Fabio Emiro
Published: June 2022

La necesidad de generar energía térmica y eléctrica, el calentamiento global causado por el aumento en las emisiones de gases de efecto invernadero, el incremento en los precios de los combustibles fósiles y la búsqueda de independencia energética, han creado una nueva industria enfocada en la generación de energía mediante el aprovechamiento de fuentes renovables. Dentro de las distintas opciones, la biomasa se constituye como la tercera principal fuente para la obtención de energía eléctrica y como la principal fuente para la generación de energía térmica. Sin embargo, los problemas relacionados con la baja densidad de los distintos tipos de biomasa y la dificultad para transportarla y almacenarla han causado la necesidad de generar productos sólidos con mayor densidad, dureza y más resistentes conocidos como pellets y briquetas. El presente trabajo busca desarrollar un análisis de la situación actual de la producción de pellets y los posibles usos que tienen, enfocándose principalmente en la revisión de los estudios de modelamiento desarrollados para el proceso de gasificación.

Published: June 2022

Los sistemas de visión artificial permiten identificar características físicas y defectos de los productos de manera no intrusiva y confiable. Debido a estas ventajas, los sistemas de visión han tenido gran aceptación en las industrias agrícola y alimenticia, ya que estas industrias requieren de una alta demanda de objetividad, coherencia y eficiencia en el control de la calidad de los productos, condiciones que los sistemas de visión artificial pueden cumplir. Este trabajo propone un procedimiento para evaluar de manera automática el estado de maduración de la piña (Ananas Comosus) variedad perolera en post-cosecha mediante técnicas de visión artificial. El procedimiento de evaluación propuesto es implementado a través de un algoritmo de procesamiento de imágenes digitales en color basado en las etapas de pre-procesamiento, segmentación, extracción de características y clasificación estadística. Se empleó, imágenes en el espacio de color HSV, segmentación por umbralización automática mediante el método de Otsu, el momento de primer orden de las distribuciones de los planos H y S como características, y el algoritmo MBSAS (Modified Basic Sequential Algorithmic Scheme– en inglés) para la clasificación. Se utilizaron 319 imágenes, de las cuales 110 imágenes fueron utilizadas en el proceso de entrenamiento y 209 imágenes fueron utilizadas en el proceso de evaluación. Los resultados obtenidos por el procedimiento de evaluación propuesto en este trabajo, fueron contrastados con el juicio de valor de tres expertos, que mostraron que el algoritmo propuesto tiene una eficiencia de evaluación cercana al 96,36%.

Published: June 2022

Las actuales condiciones de los mercados han llevado a las empresas de diferentes sectores y tamaños a adoptar tecnologías y sistemas de información y comunicaciones (TIC/SI) en sus procesos de negocio con el fin de permanecer en los mercados. Bucaramanga cuenta con un gran número de pequeñas y medianas empresas (pymes) enfocadas al sector de la confección, por lo que el estudio se centró en conocer la situación actual en la que se encuentran estas empresas en relación a la adopción de TIC/SI como soporte a sus actividades diarias. Con base en la realización de un estudio empírico con 20 pymes del sector confecciones situadas en Bucaramanga y su área metropolitana se logró identificar que el 95% de las pymes se encuentran en un nivel rezagado en la adopción de TIC/SI y el otro 5% se puede clasificar como seguidoras. No se puede hablar de empresas pioneras en la adopción de TIC/SI para este grupo de estudio en particular.

The study of biodegradation ability of polyurethane foams composite materials with lysozyme under the influence of saline solution for 2 weeks, 1, 3 and 6 months by IR spectroscopy, DSC, TGA was conducted. According to the results of IR spectroscopy under the influence of model medium there are processes of biodegradation, which are confirmed by a decrease in the intensity of the absorption band νС=О. Along with biodegradation there is a redistribution of hydrogen bonds of NH and CO groups of polymer matrix. According to DSC after incubation in saline solution there is an increase in Tg and ΔCp at the glass-transition (for polyurethane foams and composites with lysozyme in the amount of 5 wt. %), an increase in Tg and decrease in ΔCp (for composites with lysozyme in the amount of 1 and 3 wt. %), which indicates the redistribution of hydrogen bonds under the influence of saline solution and due to lysozyme release. It was found that after incubation in saline solution there is an increase in T0 and Tmax for both polyurethane foams and composite materials with lysozyme by the method of TGA. Thus, composites with lysozyme in vitro are heat-resistant materials. According to the study results of the dynamics of lysozyme release composites are capable to the prolonged release of enzyme for 5 days, the amount of which varies depending on the lysozyme content (43.85-61.97 % of the total amount of the introduced drug) and is sufficient for the manifestation of antimicrobial activity. The tissue culture method has established the biocompatibility of investigated materials. For polyurethane foam composite materials with lysozyme more active growth of fibroblastic elements than in the control and polyurethane foam and slowing down the process of cell degeneration was observed. The obtained results indicate that polyurethane foam composite materials with lysozyme are promising materials that due to the presence of the enzyme will have antimicrobial action and can be used in medical practice as polymer composites for the treatment of wounds and burns.

Published: June 2022

Bu çalışmada İbn-i Hüsam Husafi’nin Hâverânnâme adlı eserinin beş minyatürü incelenmiştir. Bunlardan dördü Tahran Gülistan Sarayı Kütüphanesi’nde bulunan Hâverânnâme nüshasında mevcuttur. Tek yapraklı çalışma ise Rıza Abbasi Müzesi’nde bulunmaktadır. Bu minyatürleri Şiraz minyatür okulu sanatçılarından Ferhad ve çırakları çizmişlerdir. Bu çalışmalarda Hz. Ali ejderha ile çetin bir mücadele içinde tasvir edilmiştir. Bu eserlerden dördü yayınlarda yer almaktadır ancak yeterince tetkik edilmemiş ve bazı konular açıklanmamıştır. Bu araştırma kapsamında ele alınan söz konusu minyatürle ilgili bir araştırmaya bugüne kadar herhangi bir yayında rastlanmamıştır. Minyatürün ustaca çizimi nakkaş Ferhad’ın elinden çıktığının önemli bir kanıtıdır. Eserde Hz. Ali çeşitli bitkilerle kaplı zeminde Düldül’e binmiş, sağ elinde Zülfikâr ile yedi başlı ejderhaya saldırmaktadır. Eserin üstünde sağda üç şahıs, onun üstünde nesta’lik şiirler, altta hayali canavarlar ve yine konuyla ilgili şiirler mevcuttur. Hâverânnâme’deki minyatürler dünyanın değişik bölgelerinde ve özellikle Batıda yapılan müzayedelerde sergilenmekte ve satılmaktadır. Envanter defterinde, üzerinde çalıştığımız tek yapraklı minyatürün geçmişi ile ilgili her hangi bir bilgi yer almamaktadır. Araştırmalarımız sonucunda bu eserin Gülistan Sarayı Kütüphanesi’ndeki Hâverânnâme’ye ait olup işaret ettiğimiz müzayedelerden satın alınmış ve önemi sebebiyle iyi korunmuş olduğunu söylememiz mümkündür. Bu çalışmanın amacı, bilinen dört minyatürü daha detaylı bir şekilde incelemek, ele alınan ve Rıza Abbasi Müzesi’nde bulunan eseri bilim dünyasına tanıtmaktır.

ABSTRACT: We described the clinical and anatomopathological findings observed in a case of nasal leiomyosarcoma in a five-year-old male Quarter Mile horse, whose main complaints were decreased sports performance and bilateral purulent nasal discharge. The nodule was observed in the nasal cavity, obstructing the left nostril and associated with purulent drainage. The nodule was of irregular shape and yellow color, measuring 19.4 cm × 6.9 cm × 4.3 cm in size, with coalescent multifocal areas that were brownish, friable, opaque, and fetid. When cut, the surface was compact, grayish-white, and smooth with yellow, friable, irregular multifocal areas, measuring 1-3.2 cm in diameter. Histopathological examination showed spindle-shaped neoplastic cells, which was negative on Masson’s trichromic stain. A diagnosis of leiomyosarcoma was established based on the morphotintorial aspects of neoplastic cells and confirmed through immunohistochemistry, with positive immunostaining for antibodies 1A4, HHF35, desmin, and S100. Leiomyosarcoma primarily affects the nasal cavity of horses and should be included in the differential diagnosis of diseases that affect the nasal cavity and cause nasal obstruction associated with dyspnea.

ABSTRACT: The application of ozone as a treatment system for reducing microbial contaminant in Nipa bowls which are local products of the Palian river basin community, Trang province in Southern Thailand, was presented in this research. The ozone treatment system was designed and investigated for its performance to reduce microbial contaminant in nipa bowl products. Parameters affecting the performance of the system were optimized as well as ozone amount and treatment time. Under optimum condition (600 mg/h ozone and treatment time of 4 hours), the microbial decontamination was 4 log reduction, and the products could be stored for one month. The moisture content and the brightness of the ozone-treated products were significantly different from the untreated products when statistically tested at 95% confidence level. The moisture contents were 9.46 ± 0.10 and 10.54±0.31 %, and the brightness (L* value) were 74.93 ± 0.49 and 70.47 ± 0.65 for the ozone-treated and untreated products, respectively. Furthermore, the residual heavy metals were investigated, and no trace of metals was reported in nipa bowl samples. As a result, the nipa bowl products had met the standards as regards safety of food containers required by the Department of Medical Sciences Ministry of Public Health, Thailand. Following this collaboration between the university and the community, over 251,564 pieces of nipa bowls were sold which generated a total income of more than 84,000 USD to the Palian river basin community.
Estimating Chicken Meat Productions of Leader Countries for 2019-2025 Years

Published: June 2022

ABSTRACT: The study predicted chicken meat production in 2019-2025 period for the leading chicken-producing countries with the help of the 1961-2018 Food and Agriculture Organization (FAO) data since chicken meat consumption is so high worldwide. The USA ranks the first place while Brazil and China take second and third places, respectively. The analysis of the pioneer chicken meat-producing countries indicates that while the portion of the USA in world production decreases, the share, particularly Brazil and China, will approach that of the USA. World chicken meat production, which was 7.56 million tons in 1961, will increase to 139.19 million tons in 2025, and this production per capita is predicted to increase to 17.0 kg in 2025 from 2.4, 5.35, 9.80, and 15.0 kg in 1961, 1981, 2001, and 2018, respectively. Indonesia, Russia, Brazil, Japan, and India will run the highest increases in production. However, the share of countries in chicken meat production will decrease from 61% to 60% in 2019-2025 compared to the 2012-2018 periods. This condition showed that apart from some leading countries, the production will keep a rapid increase in production. The increase in chicken meat production and chicken meat import worldwide will improve human nutrition, especially in developing and underdeveloped countries. Countries that run cost advantages and high-quality life standards in line with technological innovations produce processed chicken products, strengthen animal health, hygiene, and transportation standards, and attach importance to advertising activities that increase consumer demand will be more advantageous in this market.

Published: June 2022

ABSTRACT: Paper and plastic bags have been mainly used in fruit bagging of pineapple production. However, they are often discarded as agricultural wastes after harvest of pineapple fruit and threaten environment. In this study, effects of white non-woven fabric bag, expandable polyethylene bag, black plastic bag and kraft paper bag on fruit quality of pineapple cv. ‘MD-2’ were investigated. Results showed that fruits with fruit bagging showed no sunburn. When expandable polyethylene bag was used, fruits of pineapple cv. ‘MD-2’ showed better external qualities, nutrition qualities and texture properties. Expandable polyethylene bag made of degradable and recyclable materials could be recommended as a promising practice to reduce agricultural waste in pineapple production.

Abstract The goals of this paper are the cross-cultural adaptation and psychometric properties evaluation of the Brazilian version of the Clinical Perfectionism Questionnaire (CPQ), a scale that measures the tendency of a person to pursue self-demanding standards and the subjective consequences provided by achieving them or not. The original instrument was translated to Portuguese and back-translated to English. The preliminary version was judged by one of the authors of the instrument and by Brazilian specialists, producing content validity indicators. The final version was applied to a sample of 250 Brazilian undergraduate students, aged from 18 to 60 years old (M=24.9, SD=8.63), mostly female (76%). In the Exploratory Factor Analysis, data have revealed a bidimensional structure, and the other psychometric properties, such as internal consistency and validity regarding other variables, have shown adequate to the instrument. Additional analyses of unidimensional congruence reinforced the multidimensionality of the measure.

Abstract Study was planned to assess the bio-efficiency along with toxicity of iron and zinc fortified whole wheat flour in Sprague dawley albino rats. Whole wheat flour was fortified with different dosage of sodium iron EDTA (NaFeEDTA), ferrous sulphate (FeSO4), zinc oxide (ZnO) and zinc sulphate (ZnSO4). The rats (n=3) in each group were fed on fortified wheat flour for 2 months. Liver biomarkers including alkaline phosphatase (ALP), alanine transaminase (ALT), aspartate aminotransferase (AST) and bilirubin were recorded from serum samples. Increased concentration of ZnSO4 affected the liver biomarkers to be highest among all whereas, bilirubin levels were less than the rats fed on control diet. The above mentioned fortificants have negligible effect on renal biomarkers including creatinine and urea. Moreover, hematological parameters were also checked and reportedly, sodium iron EDTA fed rats presented highest amount of hemoglobin, iron and total iron binding capacity. Highest zinc level was observed in rats fed on whole wheat flour fortified with 60mg/Kg Zinc oxide. Microscopic observation of liver tissue depicted that rats fed on iron and zinc fortified wheat flour have more toxic effects whereas, histopathology presentation of kidney tissue has least toxic impact. It has been concluded that mandatory fortification of wheat flour with iron and zinc may cause increased serum biomarkers along with toxicity of vital organs like liver, hence fraction of wheat flour may be fortified to fulfill the requirements of deprived and vulnerable group.
