Authors: Zhu Zanbin , Li Yubin , Gong Shoufu
Published: August 2022

In the summer heat season, the performance of greenhouse cooling system is the key factor of the greenhouse crop pollination and fruit formation. Scientific design of greenhouse cooling system and intelligent control of cooling equipment can ensure the normal growth of greenhouse crops and save energy. In this paper, the thermal equilibrium theory of greenhouse is analyzed, and the thermal environment model of glass greenhouse is established based on the theory of engineering thermophysics combined with greenhouse environmental regulation. This study uses CFD (Computational Fluid Dynamics) simulation technology to simulate the change of greenhouse temperature field and perform experimental analysis, and designs an intelligent greenhouse temperature control cooling system scientifically. It provides reference for the design of IOT (Internet of Things) cooling system in glass greenhouse in theoretical analysis and engineering practice.
Effect of envelope characteristics on the accuracy of discretized greenhouse model in TRNSYS

Published: August 2022

TRNSYS is a common tool that has been recently used to model and simulate greenhouse energy demand and utilization using building energy simulation (BES). Previously, a single thermal point was used for validation, ignoring the distribution of greenhouse climate parameters, especially the temperature. Temperature variation often leads to thermal stratification, prompting researchers to propose volume discretization in dynamic greenhouse simulations. In this context, the effect of envelope characterization on the accuracy of discretized TRNSYS BES model was developed to determine the best BES model under a free-floating regime. The combination of the number of layers [double (D) and single (S)], geometry mode [3D and manual (M)], and layer type [massless (M) and no glazing window (W)], led to the development of five models: D_3D_M, D_3D_W, D_M_M, S_3D_W, and S_M_M. The simulation was performed in a standard radiation mode, and the output parameters were temperature and relative humidity (RH). R2 and the root square mean error (RSME) were used to check the fitness and degree of deviation, respectively, to validate the models. Analysis of variance (ANOVA) was employed to investigate the significant differences among the models, whereas contour plots were used to compare the distribution pattern between the significant models and experimental data. Validation of the models showed that the obtained R2 values ranged from 0.86 to 0.95, and the RSME values for the temperature were between 2.64 °C and 3.91 °C. These values were 0.91–0.93 and 19.72%–30.32% for RH. The ANOVA (p < 0.05) result exhibited significant differences between the S-scenario models and experimental central points in temperature and RH. The D- and S-layer scenarios with a 3D geometry and massless layer showed similar distribution with their corresponding experimental greenhouses. Hence, 3D_M was regarded as the best combination in the discretized BES model.
Heterotaxy
Authors: Lahel Ranjit Singh
Published: August 2022

Heterotaxy syndrome is an uncommon disease, with an incidence ranging from 1 in 6000 to 1 in 20,000 live births.[1] This syndrome is characterized by major cardiac vascular malformations, congenital asplenia, polysplenia, and abnormal arrangement of the chest and abdominal organs. Radiological investigations such as radiographs, sonography, and computed tomography scan play a pivotal role in ascertaining the correlation between clinical symptoms of the patient and the extent of anatomical aberration in the form of thoracic or visceral “situs” abnormalities. The case in this report is a rare variant of heterotaxy, which cannot be stratified into any of the existing subsets for heterotaxy syndromes. The relevant investigations thereof and their relevant findings have been discussed in detail.

Background:

Preoperative fasting is a universally followed principle in patients undergoing elective surgeries to minimize the risk of pulmonary aspiration.

Objectives:

The main objective is to compare ultrasound (US)-guided gastric volume after encouraging clear fluids till 1 h and 2 h preoperatively.

Methodology:

We carried out a prospective observational study in a multispecialty children's hospital, wherein pediatric patients of American Society of Anesthesiologists (ASA) I and ASA II physical status undergoing elective surgeries and between the age group of 2 and 10 years were enrolled in the study on sample size of 60. The study tool used was US Mindray machine with a linear probe of frequency 10–12 hertz. The study was approved by hospital ethical committee. Those patients who could take clear fluids 3 ml/kg 2 h prior to surgery as per standard guidelines were placed in Group A and those who received 3 ml/kg of clear fluids till 1 h before surgery placed in Group B. US assessment of gastric volume was done in the preoperative area.

Results:

There is no significant difference in gastric volumes and antral cross-sectional area in both the groups. There is no significant increase in incidence of postoperative nausea and vomiting in Group B where clear fluids were encouraged till 1 h prior to surgery.

Conclusion:

According to the study, we can conclude that clear fluids can be encouraged till 1 h preoperatively in pediatric patients undergoing elective surgeries.

Authors: Bobdey Saurabh , Mookkiah Ilankumaran , Narayan Shankar , Pawar AA
Published: August 2022

Introduction:

Stress cannot be considered a simple “stimulus-response reaction,” but it is a complex interaction between an individual and the environment, comprising subjective perception and evaluation of stressors and then responding in a highly personalized manner. The present study was conducted to assess the personality traits of trainees and explore their association with levels of perceived stress.

Materials and Methods:

A cross-sectional, questionnaire-based study was conducted on 911 trainees. For data collection, two instruments were used – Perceived Stress Score by Cohen for assessing stress among the subjects and Revised Neuroticism–Extraversion–Openness Personality Inventory for personality assessment.

Results:

Overall, the total mean Perceived Stress Score was 12.60 ± 5.62 indicating less than average stress. Only 10.98% of those tested had a score of 20 or more indicating perception of very high stress. Trainees with high perception of stress had significantly higher scores of neuroticism (57.82 ± 9.02, P < 0.05) including all the subfacets. In contrast, trainees with low or average stress perception had significantly higher scores of extraversion (53.57 ± 8.03, P < 0.05) and conscientiousness (54.25 ± 10.30, P < 0.05).

Conclusion:

The present study is the first of its kind which tries to not only assess the stress levels among trainees but also explore and compare their personality characteristics. The study brings out that majority of the trainees had average stress and provides definitive evidence of association between high neuroticism, low extraversion, and perception of high stress, and offers a window of opportunity to explore options for remedial action such as incorporation of stress coping-up techniques in Armed Forces training curriculum.

Published: August 2022

Background:

Anterior cruciate ligament (ACL) injuries are the commonly seen and potentially devastating injuries in sportsperson and high-demand professionals like military personals. The return to the preinjury status even after the successful ACL reconstruction surgery is not assured. The aim of this study was to assess the pattern and profile of ACL injuries seen in military personnel.

Materials and Methods:

Five hundred and twenty-four patients who were operated at our center with ACL reconstruction and were meeting the inclusion criteria were included in this study. Patients were evaluated with detailed history and clinical and radiological examination.

Results:

Five hundred and twenty-four patients were evaluated at a mean of 7.86 months. The mean age was 29.64 years (range: 20–46 years). Five hundred and twenty patients were male and four were female. The mode of injury was sporting activity in 244 (46.6%), military training-related activity in 180 (34.3%), and other activities in 100 (19.1%). Football and basketball were the most common sporting activities in which ACL injuries were sustained, while landing injuries during 9-feet ditch activity (n = 109) were the single most common activity in which ACL injuries were sustained. An isolated ACL tear in 235 patients was the most common type of injury seen, while the meniscus injuries (medial and lateral meniscus) in 149 (28.4%) and 115 (21.9%) patients, respectively, were the most commonly seen associated injuries.

Conclusions:

ACL injuries are a common occurrence in armed forces. Injury during sports and landing injuries in 9-feet ditch are the common modes by which patients sustained ACL injuries.

A 37-year-old male patient known to have polycystic kidney disease (PKD) for the past 5 years presented with a 2-day history of severe chest pain at rest that was confirmed as acute inferior myocardial infarction (MI). He was a known hypertensive for the past 5 years with a difficult-to-control blood pressure, but with preserved renal function. He had no family history of similar illness and has no personal history of diabetes mellitus, dyslipidemia, smoking, alcohol consumption, or recreational drugs use. Apart from elevated blood pressure of 150/100 mmHg, physical examination was unremarkable. He was found to have dyslipidemia with high-density lipoprotein cholesterol of 0.87 mmol/l and hypertriglyceridemia (2.7 mmol/l), but other serum lipid fractions and fasting plasma glucose were within normal limits. His echocardiogram showed normal sizes of all cardiac chambers with preserved left ventricular (LV) function, inferior wall hypokinesia, and Grade I LV diastolic dysfunction, and he had no aortic aneurysm. He was admitted for 5 days, treated conservatively, and discharged after resolution of symptoms, troponin, and raised ST segments. To the best of our knowledge, this is the first report from Nigeria illustrating the rare association between PKD and acute MI in the young.

Published: August 2022

Introduction:

Resilience is one of the competencies that enable nurses to adapt to stressful risk factors at work and demonstrate a healthy and stable psychological performance. The present study aimed to investigate the predictive role of resilience on job stress among Iranian nurses.

Methods:

The current cross-sectional study was conducted in Ahvaz, Iran, with participation of 200 nurses in May 2019. Participants were recruited via stratified random sampling. The resilience indicators and job stress data were collected by the Connor–Davidson Resilience Scale and OSIPOW Job Stress Questionnaire.

Results:

The results showed a significant negative correlation between resilience and job stress (r = −0.824, P < 0.05). Similarly, a significant linear regression existed between job stress and resilience (β = −0.824, P < 0.05) in such a way that resilience predicted 67.9% of the job stress variance in the participants (R
2 = 0.679). In addition, it was revealed that the multi-aspect model could significantly predict job stress based on linear resilience indicators (P < 0.05).

Conclusion:

The results indicated that resilience indicators have a significant relationship with job stress, and this relationship can be used to predict changes in job stress based on resilience. Therefore, it is strongly recommended that resilience improvement programs should be developed and implemented for nurses.

Authors: Birkenbeuel J.L. , Goshtasbi K. , Adappa N.D. , Palmer J.N. , Tong C.C.L. , Kuan E.C.
Published: August 2022

Background: There is a paucity of reporting on recurrence patterns of de-novo sinonasal squamous cell carcinoma (DN-SCC) and inverted-papilloma-transformed sinonasal squamous cell carcinoma (IP-SCC). Method: A systematic literature review queried studies comparing recurrence patterns in patients with both DN-SCC and IP-SCC. Primary outcomes included local and regional recurrence and rates of distant metastasis. Of the 595 studies screened, eight were included. Results: Patients with DN-SCC had significantly higher rates of positive margins, advanced T classification (T3/T4), treatment with chemotherapy and radiotherapy. There were no significant differences in local recurrence or regional recurrence. Overall risk of distant metastasis was lower in IP-SCC. DN-SCC, compared to IP-SCC, is more likely to present with advanced TNM classification and have positive margins after surgical resection, which may affect rates of distant metastasis and recurrence. Conclusions: The findings in this study suggest IP-SCC may be a less aggressive malignancy compared to DN-SCC, with the possibility of a reduced role for adjuvant therapy in IP-SCC. Further studies are required to better understand differences in tumor biology and treatments strategies between IP-SCC and DN-SCC.

EVALUATION OF FOLIAR DISEASE INCIDENCE AND SEVERITY OF MANGROVES IN UNIVERSITI MALAYSIA TERENGGANU
Authors: M. ABDULLAH MAIZAH , MOHD ALWI NOORSHAZILA , SAHIBU AZWANI
Published: August 2022

Mangroves are an important ecosystem because of their ecological roles and services, particularly in nutrient cycling and carbon sequestration. However, habitats have declined over the year, mostly due to anthropogenic and natural threats. Mangrove plant diseases caused by pathogenic fungal invasion are poorly described. The status of diseased mangroves remained unknown, primarily in Malaysia. The current study evaluates the disease incidence and severity of mangrove trees in the Universiti Malaysia Terengganu (UMT) campus. This study aimed to determine the dominant type of foliar disease in the UMT campus and identify the most affected mangrove species using Disease Incidence and Disease Severity approach. 30 leaves from each of five mangrove species; Lumnitzera racemosa, Rhizophora apiculata, Hibiscus tiliaceus, Avicennia alba and Sonneratia caseolaris were collected, observed and analysed for the Disease Incidence and Disease Severity. A total of six types of foliar diseases were observed, with leaf blight as the dominant, followed by brown leaf spot, insect graze, grey leaf spot, black leaf spot and anthracnose. Mangrove trees at Jalan Biawak have the highest percentage value of Disease Incidence and Disease Severity compared to mangroves at Pusat Islam UMT. Fungal invasion rate variation could be caused by factors such as temperature, humidity and mangrove species’ resilience toward fungal invasion. Therefore, further study needs to be done to understand this issue better.

Building differential dynamical systems to describe the changing relationship among chemical components is a vital aspect in chemistry. In this present manuscript, we put forward a new fractional-order delayed Brusselator chemical reaction model. By virtue of contraction mapping principle, we investigate the existence and uniqueness of the solution of fractional-order delayed Brusselator chemical reaction model. With the aid of mathematical analysis technique, we consider the non-negativeness of the solution of the fractional-order delayed Brusselator chemical reaction model. Making use of the theory of fractional-order dynamical system, we explore the stability and Hopf bifurcation issue of the fractional-order delayed Brusselator chemical reaction model. By designing a reasonable controller, we have availably controlled the time of emergence of Hopf bifurcation of the fractional-order delayed Brusselator chemical reaction model. A sufficient criterion guaranteeing the stability and the onset of Hopf bifurcation of the fractional-order controlled delayed Brusselator chemical reaction model is set up. Computer simulations are implemented to validate the theoretical findings. The derived fruits of this manuscript have great theoretical significance in controlling the concentrations of chemical substances.

La ganadería es una de las principales actividades económicas para la generación de ingresos en la subregión del Oriente antioqueño, la cual cuenta conun área importante en praderas de pasturas nativas, donde los animales seleccionan de manera voluntaria su dieta. El propósito de esta investigación fueevaluar la preferencia de consumo de bovinos jóvenes, que se encontraban pastando en praderas compuestas por gramas nativas, durante la época seca ylluviosa. Para determinar el índice de selectividad (IS) se calculó la proporción de especies presentes antes del pastoreo (transecto control) y la proporción deespecies consumidas (transecto vaca), en un área de 3,5 ha. Para la proporción de especies consumidas del transecto vaca se determinó el consumo de losbovinos en periodos de 6 minutos, en horas de la mañana y en horas de la tarde, durante 7 días en cada época. Los resultados de la prueba de selectividadsugieren diferencias en la preferencia entre las dos épocas evaluadas, siendo la especie Axonopus compressus preferida en época seca, y Panicum polygonatum preferida en época lluviosa. La selectividad animal es relativa debido a que presentó variación de acuerdo a la época del año, a la disponibilidad y comportamiento de las especies vegetales presentes en las praderas.
Vulnerabilidad humana e identidad católica: claves para una sociedad más humana
Authors: Ros Codoñer Javier
Published: August 2022

El presente artículo indaga algunos de los elementos sociales que tras el confinamiento debido a la pandemia de covid-19 han aflorado y consolidado en un nuevo escenario social, así como las líneas maestras que desde la identidad católica se hacen imprescindibles para abrir vías hacia una sociedad donde lo humano pueda desarrollarse en todos los ámbitos. La enfermedad, la impredecibilidad y la vulnerabilidad se han abierto paso al tiempo que el Estado y las redes tecnológicas globales buscan afianzarse como pretendidos y únicos garantes de las relaciones sociales. Frente a ello, la Iglesia católica es capaz de aportar su sabiduría de origen trascendente aquilatada en siglos de experiencia pues siendo fiel al mensaje evangélico recibido, es capaz de erigirse en referente moral que nos permita repensar los nuevos escenarios sociales desde una fe, una esperanza y una caridad encarnadas en actitudes personales. Actitudes personales que, fraguadas en la comunidad cristiana bajo el modelo de las denominadas minorías creativas, trascienden la autorreferencialidad y permean el tejido societario haciendo frente a los paradigmas tanto individualistas como colectivistas siempre enemigos de la verdad del hombre y de sus relaciones.
De generación en generación: metodología para la reconstrucción de la memoria e historia de la Diócesis de Sonsón-Rionegro
Authors: Valencia Giraldo Sara
Published: August 2022

Reconstruir la memoria es una tarea apremiante sobre todo en estos tiempos en los que se está constatando una profunda pérdida de esta facultad fuera de un creciente desinterés de las nuevas generaciones por arraigarse en el pasado y reconocer la identidad que las generaciones precedentes han construido. Generar vínculos entre las generaciones y valorar la gloria del pasado, para apreciar el legado dejado por los protagonistas de los primeros tiempos es también una necesidad de la Diócesis de Sonsón-Rionegro. Este texto presenta el diseño de una ruta metodológica específica para la reconstrucción de la memoria y la historia de la Diócesis en el contexto de sus sesenta años de acción pastoral en la región del Oriente antioqueño. Para alcanzar esta meta, se realizó un proceso de búsqueda, recolección y análisis de datos mediante la revisión de la literatura en torno a las categorías: relato, memoria e identidad; por medio de lo cual se concluyó que el relato de vida es la herramienta metodológica más apropiada para dar respuesta a este tipo de necesidades, ya que capacita a las personas para narrar su historia, producir conocimiento y dar sentido a su existencia; del mismo modo que genera el espacio vital para la transmisión de la tradición de generación en generación. En este sentido, el relato en el marco de lo anecdótico, es también una forma de acceso a la memoria de una colectividad, fundamento de la identidad
El abecé para la defensa de la vida: Riesgos de las TRA
Authors: Moya Graciela , Vallejo Cardona Jesús David
Published: August 2022

Urge en la escena actual el imperioso deber de indicar el momento del inicio de la vida humana, porque permite establecer criterios y pautas bioéticas para definir los límites y alcances de la implementación de las técnicas de reproducción asistida (TRA). Principios como el respeto por la dignidad de la vida humana, la obligación de no dañar, el respeto por las personas con discapacidad, entre otros, se contraponen con aquellos de orden consensual como la libertad procreativa, la beneficencia reproductiva, la privacidad y la autonomía. Por ello, en este trabajo se presentan los fundamentos y los datos que la ciencia ha descrito sobre el origen y desarrollo del ser humano desde su concepción, acompañados de los argumentos ontológico, moral y jurídico, para llegar a concluir que las TRA requieren un marco normativo específico, que responda a los criterios de la embriología, que reconozca la necesidad de una protección completa del ser humano desde el mismo momento de su concepción.

Ocuparse de sí (epimeleia) como autoformación (selbst bildung): a propósito del gesto pedagógico y filosófico de Michel Foucault
Authors: Runge Peña Andrés Klaus , Muñoz Gaviria Diego Alejandro
Published: August 2022

El ocuparse de sí se comprende pedagógica y filosóficamente como un ejercicio auto formativo que tiene implicaciones en la conducción de la vida como una tarea constante. Para argumentar este supuesto se tendrán en cuenta los siguientes aspectos: en primer lugar una reconstrucción, de la problemática filosófica, histórica y pedagógica, existente en el mundo teutón, en torno al concepto de formación, sus teorías y dimensiones. Resaltando en esta problemática histórico – conceptual la pertinencia de la autoformación (selbstbildung) como emancipación. En el segundo momento se tematizan las tesis filosóficas y pedagógicas que permitieron al movimiento neohumanista alemán recuperar la epimeleia griega y latina y establecer desde allí la base de su propuesta pedagógica de la formación como autoformación. La autoformación es la responsabilidad que el ser humano tiene en la tarea constante de hacer algo de sí, una suerte de catártica que implica la transformación de la subjetividad. Por último, se recupera en la obra de Foucault el llamado a ocuparse de sí como gesto central para la pedagogía y la filosofía que se consideren críticas. Aquí la idea de crítica deviene en autocrítica o crítica del sujeto sobre las condiciones que han hecho posible la configuración de sí.

Parameters observed in this study were number of leaves, leaf length, and wet weight of plantlets. The data were analyzed by using The Analysis of Variance and further tested using Tukey Multiple Range Test (Tukey Test) (P=0.05). The results showed that KH2PO4 170 mgL-1 was the best concentration for multiplication of Dendrobium Sonia as shown by the parameters the diameters of number of leaves (4,41 sheet), leaf length (1,16 cm), and wet weight of plantlets (0,10 mg) and Kinetin 1 mgL-1 was the best concentration for multiplication of Dendrobium Sonia as shown by the parameters the diameters of number of leaves (4,05 sheet), leaf length (0,97 cm), and wet weight of plantlets (0,09 mg). By interaction, the addition of various concentrations of KH2PO4 and Kinetin significantly affected the number of leaves with the best treatment adding KH2PO4 160 mgL-1 and Kinetin 1 mgL-1 MS with an average leaf number of 4.99 strands.
Mutation Analysis of The Phenylalanine Hydroxylase Gene in Phenylketonuria Patients from Different Regions of Azerbaijan
Authors: Lala Sameddin Huseynova
Published: August 2022

The present study aimed to determine frequencies of mutations in the phenylalanine hydroxylase gene (PAH) in 30 patients diagnosed with phenylketonuria, from 633 person who presented to Scientific Research Pediatric Institute of the Ministry of Health of Azerbaijan and hospitals of different regions of Azerbaijan over the period from 2016 to 2020. More than 600 mutations in the PAH gene in exons 6, 7, 8, 11 and 12 have been detected in various countries around the world. Among them, 18 different mutations were found in Azerbaijani patients (V245V, R261Q, Q232Q, V245V, P281L, R241C, L385L, V399V, E280K, R261X, A434D, R176X, Ex6-96A> G, R241C, R243Q, R256Q). The R261Q mutation in exon 7 was observed in seven patients from 30 patients. In this study, we identified mutations in the PAH gene and to evaluate the genetic heterogeneity of PKU disease in 30 Azerbaijanian patients who had been referred to Lankaran, Masalli (Southern region of Azerbaijan), Qabala, Oguz, Zagatala, Balakan (North-western region of Azerbaijan), Guba, Gusar, Khachmaz and Khudat (Northern region of Azerbaijan) regions. From this experiment, 7 of 30 PKU patients had the same mutation. Our analysis of the R261Q mutations was nearly similar to that observed in Southern region of Azerbaijan. The R261Q mutation in exon 7 with a relative frequency of 23.3 % is G → A substitution leads to conservation of arginine amino acid to glutamine amino acid at codon 782 of PAH. The another major mutation in our study was R241C (10%), which is similar to the data obtained in population of Northern region of Azerbaijan, R243Q (6.6%) and R252Q (6.6%). Studies have shown that this mutation is most common in the Azerbaijani population. Genetic drift and founder effect may have also played a role in the mutation spectrum we observed. The data obtained in our study can also be used in the development of genetic tests for phenylketonuria. Phenylketonuria (PKU) is an autosomal recessive genetic disease, caused by the phenylalanine hydroxylase (PAH) deficiency in the metabolic pathway, which prevents phenylalanine from being converted into tyrosine, leading to a large amount of phenylalanine discharged from the urine. Therefore, it is necessary to establish a simple, fast, accurate and reliable PKU molecular diagnostic method for clinical diagnosis.
