Authors: Liu Huan , Fu Zheng
Published: April 2024

Shortage of funds and inefficient financing have been the main problems faced by science and technology-based SMEs. Supply chain finance is aiding science and technology-based SMEs in obtaining financing opportunities and reducing the cost and difficulty of financing. This paper constructs a model for assessing financing efficiency with the help of Data Envelopment Analysis (DEA). And combined with the financing constraints commonly encountered by SMEs in the financing process, which affect the financing efficiency, it proposes a mediation effect model to analyze the influence of financing constraints. At the same time, the financing constraints faced by SMEs in science and technology are examined through an empirical model, and the mitigating effect of supply chain finance on financing constraints is analyzed through a model test. In the analysis of financing efficiency, the interest expense and pre-tax debt financing cost of DL science and technology-based companies are decreasing after supply chain finance financing. The interest expense is reduced by 2,009,200,200 in 2022 compared with 2019, and the pre-tax debt financing cost decreases to 6.12%. The proportion of supply chain financing in financing loans is more than 50%, the speed of capital turnover and financing efficiency have significantly improved, and the debt servicing capacity, operating capacity, and profitability have been improved.

Authors: Yang Hui
Published: April 2024

Addressing the challenges of integrating industry and education, this research unveils a knowledge monitoring model aimed at refining the talent cultivation process, particularly in higher trade colleges and universities in China. The “2+1” model is developed in response to issues such as ineffective teaching practices, an abundance of practical courses without depth, and weak university-industry collaboration. Based on a comprehensive analysis of the talent cultivation demand and integration policies, this model employs a multi-scale integration network to foster a meaningful fusion of industry and education. Through case study evaluation, a strong positive correlation (0.727, significant at the 0.01 level) between overall satisfaction and the accomplishment of skills cultivation highlights the model’s effectiveness. This contribution not only advances our understanding of talent development in vocational education but also has significant implications for the broader application of industry-education collaborative models.

Authors: Marcinkus Madara , Dirveiks Ilmārs
Published: April 2024

The analysis in this research focuses on folk schools, which are among the oldest educational buildings in Latvia. These schools played a significant role in the advancement of Latvian national culture and the initiation of Latvian education. Throughout history, the preservation and fate of this architectural heritage have consistently relied on socio-economic and political factors. Even in the present day, due to urbanization, school restructuring, and a lack of societal appreciation for their historical significance, these buildings remain vulnerable to complete deterioration and eventual disappearance. The historical form of folk schools as an educational network no longer exists, and today their architectural heritage serves as vanishing proof of the past, with its value primarily recognized within cultural and historical contexts. This study analyzes 114 identified folk school structures situated in two historical regions of Latvia. It delves into their construction history and architectural characteristics while elucidating the inherent risks and potential cultural significance these edifices hold in the contemporary landscape of Kurzeme and Zemgale.

Published: April 2024

Objective

This study aimed to estimate the incidence rate and clinical characteristics of inflammatory bowel disease (IBD) in the Chinese population, specially comparing the North and South regions.

Methods

We designed a questionnaire survey for patients diagnosed with IBD and conducted a systematic literature search in PubMed, China National Knowledge Internet, and Wanfang digital database, covering studies published between 2012 and 2022. Meta-analysis was performed to determine the overall incidence rate and prevalence of clinical manifestations of Crohn’s disease (CD) and ulcerative colitis (UC) in mainland China. Clinical phenotypes and demographic characteristics were calculated with 95% confidence intervals (CI). A comparison between the northern and southern regions was also conducted.

Results

The questionnaire survey included 440 patients, and 64 publications were included for Meta-analysis. The overall incidence rates of IBD, CD, and UC were 1.36 (95% CI: 0.79-2.33) per 100,000 person-years, 0.23 (95% CI: 0.09-0.58) per 100,000 person-years, and 1.12 (95% CI: 0.69-1.80) per 100,000 person-years, respectively. The incidence rates of IBD, CD, and UC were all higher in southern China compared to the North. Clinical characteristics of 440 IBD patients from the questionnaire and 2,821 CD patients and 12,809 UC patients from the literature were analyzed. There were more male patients compared to female patients. CD cases in the North exhibited earlier disease diagnosis (P < 0.01), more upper gastrointestinal lesions (P < 0.01), and higher hospitalizations rates (P < 0.01) compared to the South. UC cases in the North had higher severity (P < 0.01), anemia rates (P < 0.01), and weight loss (P < 0.01) compared to the South.

Conclusions

The incidence rates of IBD, CD, and UC were higher in southern China than in the North. Northern patients exhibited more severe symptoms compared to their southern counterparts.

El Acuífero Región Carbonífera es uno de los 28 sistemas hidrogeológicos existentes en el estado de Coahuila, y también de los que más presiones sufre debido a la actividad minera y la sobreexplotación. Este estudio se enmarca en la porción oeste de dicho acuífero, abarcando el Ejido Morelos y la Colonia El Nacimiento, ambos en el municipio Melchor Múzquiz. En dicha área se tomaron muestras en 14 sitios (4 pozos, 6 norias, 2 manantiales y 2 secciones del río Sabinas), con el objetivo de caracterizar desde el punto de vista hidrogeoquímico e isotópico estos cuerpos hídricos y así obtener un modelo conceptual de dicho sector. Los resultados obtenidos muestran la variabilidad química de las aguas muestreadas, clasificándose como aguas de tipo bicarbonatada-cálcica, bicarbonatada-sódica, sulfatada-cálcica y clorurada-sódica, lo cual sugiere la ocurrencia de variados procesos que afectan la calidad del recurso, entre ellos la salinidad. Desde el punto de vista isotópico se propone un origen meteórico para la mayoría de los cuerpos hídricos en estudio, cuya zona de recarga proviene de la sierra de Santa Rosa. Sin embargo, procesos como la evaporación superficial, la disolución de sales, y el intercambio iónico generan variabilidad química y fraccionamiento isotópico, lo que condiciona firmas isotópicas más pesadas, y aguas más enriquecidas y salinas. Estos elementos se representan en un modelo geohidrológico e isotópico conceptual, que integra ambas interpretaciones y muestra la complejidad hidrogeológica de la región en términos de calidad del recurso.

La cuenca baja del río Lurín es una de las últimas grandes extensiones de áreas verdes en Lima, capital de Perú, sin embargo es afectada por diversas actividades antrópicas. Ante esta situación, y con el objetivo de mejorar el manejo de los recursos hídricos, se implementó un modelo de calidad del agua con el módulo GESCAL del sistema de soporte a la decisión AQUATOOL. La construcción de la red hidrográfica del río se hizo a partir de los datos recogidos en salidas de reconocimiento, mientras que para modelar la calidad del agua del tramo bajo del río se desarrolló un programa de monitoreo que tuvo como principales parámetros al oxígeno disuelto, DBO5 y Escherichia coli. Con la información obtenida se determinaron primero los coeficientes de degradación de materia orgánica, desoxigenación y reaireación de las secciones del río, y finalmente se parametrizó el modelo. La calibración del modelo en oxígeno disuelto obtuvo un rendimiento de “bueno” a “muy bueno”, con valores de 0.77, 0.23 y 0.8058 para E, RSR y r2, respectivamente; para el caso de la DBO5, se obtuvieron valores de 0.99, 0.01 y 0.9995 para E, RSR y r2, respectivamente; y para la Escherichia coli, valores de 0.99, 0.01 y 0.9993 para E, RSR y r2, respectivamente. Finalmente, se simularon cuatro escenarios, a partir de los cuales se determinó que para alcanzar los objetivos ambientales es necesario mejorar los procesos de las plantas de tratamiento de aguas residuales (PTAR) Manchay y San Bartolo; clausurar el canal de regadío proveniente de la capilla de la zona, e implementar una PTAR en el distrito de Pachacámac. El estudio demuestra la utilidad del sistema AQUATOOL/GESCAL en la toma de decisiones informadas para la gestión de los recursos hídricos a nivel de cuenca.

Los contaminantes emergentes son sustancias que en los últimos años han venido siendo identificados y cuantificados con mayor frecuencia en distintos tipos de agua; esto, asociado con el impacto ambiental, ecológico y de salud pública que generan. Se caracterizan por estar en bajas concentraciones, lo cual provoca que su detección sea costosa y especializada. Es por ello que en los países desarrollados existen programas de monitoreo y seguimiento, mientras que en países Latinoamericanos recién se empiezan a detectar sin una programación o frecuencia definida. El presente artículo presenta el diseño y la aplicación de una herramienta computacional denominada plugin CE, la cual es un plugin del software QGIS, escrito en código Python; dicha herramienta pretende ser un soporte técnico para la determinación de contaminantes emergentes en sectores industriales mediante una identificación asociada con el tipo de sector empresarial y el procesos productivo que se llevan a cabo, al mismo tiempo tiene la capacidad de enlazarse con el catastro de redes sanitarias e identificar posibles puntos de muestreo. Como resultado del plugin se encuentra una guía paso a paso para su uso y un caso de estudio llevado a cabo en la ciudad de Bogotá.

Uno de los efectos ambientales más conocidos de las ciudades es que inducen a la impermeabilización de suelos que a su vez incrementan los impactos del calentamiento global. La construcción de infraestructura, como calles y banquetas hechas de pavimento o concreto propician una disrupción entre las actividades de la población y el ciclo hidrológico natural. El cambio de uso de suelo y la extracción para el abastecimiento de agua potable sin criterios de sostenibilidad urbana agrava la situación en muchas ciudades del mundo. Para el desarrollo de este trabajo se efectuó una lectura comparada sobre el manejo de las aguas pluviales en los contextos del ciclo integral del agua urbana y la sostenibilidad. Se revisaron 61 artículos que permiten observar que los sistemas urbanos de drenaje sustentable son una alternativa esencial para contrarrestar los efectos del cambio climático y mitigar las variaciones importantes en la distribución de los patrones de pluviosidad anual en diferentes regiones, especialmente en ciudades latinoamericanas.

Role of Genetic Variants AGT rs699 and ACE2 rs2106809 in Increasing the Risk and Severity of COVID-19 Infection in Iraqi Patients
Authors: Hussein Ghazwan Faisal , Al Saadi Ali Hmood
Published: April 2024

The main aim of our study was to determine if the ACE2 rs2106809 and AGT rs699 polymorphisms increase the risk and severity of Covid-19 infection in Iraqi patients. This case-control study included 102 patients (mean age 52.66±18.82 years) and 92 healthy (mean age 37.88±14.19 years). The patients were grouped based on severity: hospitalized (n = 57) and non-hospitalized (n = 45). Demographic and comorbidity data was also collected. Genotype distribution of two selected SNPs ACE2 gene rs2106809 and AGT rs699 polymorphisms was performed by allele-specific PCR (AS-PCR) and sanger sequencing. The ACE2 rs2106809 C allele was associated to an increased risk of Covid-19 infection and the severity in males but not in the females (C vs. T OR = 3.04 p=0.01 and C vs. T OR = 4.9, p = 0.03, respectively). While AGT rs699 TC genotype was associated with 2.96 folds higher risk of Covid-19 infection (TC vs.TT, CC OR =2.96, 95%CI = 1.12–6.44; p = 0.02).  The AGT rs699 was not associated with the severity of infection. Among outpatients, benign conditions were associated with a lower risk, however older age males and comorbidities increased the risk. We concluded that the genetic variant of rs2106809 ACE2 in males was significant with a risk of infection and severe clinical course because it could be located on the X-chromosome, and at the same time AGT rs699 polymorphism had an impact on the increased risk of Covid-19 but had no relation with the severity of Covid-19.
Diagnostic Potential Role of CXCL3 and Leptin Levels in Breast Cancer
Authors: Neamah Abbas S. , Lafta Fadhel Mohammed
Published: April 2024

The risk of breast cancer development is believed to be attributed to the alterations of a number of key biological components. Within this context, elevated levels of some chemokines that act as growth factors and can promote cancer development. The current study was designed to evaluate CXCL3 (a chemokine C-X-C Motif Ligand 3) and leptin (a peptide hormone synthesized by adipose tissue with cytokine activity) serum of Iraqi breast cancer patients in comparison to healthy controls. A total of 90 participants consisted of 60 patients diagnosed with breast cancer and 30 healthy women as control group were enrolled into this case-control study. Venous blood samples were collected from all participants to evaluate CXCL3 and leptin serum levels using ELISA. The results demonstrated significantly (P≤0.001) higher mean levels of CXCL3 and leptin in breast cancer patients (1.19±0.10 ng/mL and 130.44± 3.72pg/mL) compared to those of their healthy counterparts (0.430± 0.02\ng/mL and 57.1± 3.2pg/mL respectively). Interestingly, vast majority of the assessed breast cancer cases (up to 95-98%) showed to have elevated serum levels of both of the assessed potential biomarkers (CXCL3 and leptin). The present study results suggest an association of both CXCL3 and leptin in breast cancer pathogenicity. This supports the possibility of utilizing these potential biomarkers for breast cancer early detection and diagnosis.

Influence of a Magnetic Field on the Structure, Morphology and Gas Sensing Characteristics of ZnO: Al Thin Films Prepared by Pulsed Laser Ablation
Authors: Abbas Zahraa Marid , Abbas Qusay Adnan
Published: April 2024

In this work, aluminium-doped zinc oxide (AZO) nanostructure at 0.3 wt% and 0.5 wt% Al was synthesized using the pulse-laser ablation technique in liquid(PLAL) using pulsed Nd: YAG laser of a fundamental wavelength of (1064 nm). The process was done in the absence and presence of an external magnetic field. The deposited AZO nanostructures by drop-casting on etched-Si wafers were examined by different techniques. The XRD test illustrates enhancing the crystallinity of the prepared thin films by applying an external magnetic field. The FESEM images displayed the change of nanostructure to nano-sheets of high surface area after using a 77.2 mT permanent magnet placed behind the target during the ablation process. The gas sensor based on the AZO nanostructures has higher sensitivity against NO2 than H2S. Increasing the Al ratio from 0.3 wt% to 0.5 wt% changed the properties of the prepared samples to have small porosity and small surface area, which negatively affected the properties of the sensor

Authors: Hamdan Israa Abd Al-Hasan , Tomma Jumbad H.
Published: April 2024

This work includes the synthesis of new ester compounds containing two 1,3,4-oxadiazole rings, 15a-c and 16a-c. This was done over seven steps, starting with p-acetamido-phenol 1 and 2-mercaptobenzoimidazole 2. The structure of the products was determined using FT-IR, 1H NMR, and mass spectroscopy. The evaluation of the antimicrobial activities of some prepared compounds was achieved against four types of bacteria (two types of gram-positive bacteria; Staphylococcus aureus and Bacillus subtilis, and two types of gram-negative bacteria, Pseudomonas aeruginosa and E. Coli), as well as against one types of fungus (C. albino). The results show moderate activit against the study bacteria, and the theoretical analysis of the toxicity demonstrates non-toxicity with acute oral human toxicity. Also, the toxicity of these compounds in rats was weak. A molecular modelling study explains that these compounds possess good binding with lung cancer proteins.

The present paper shows a numerical comparison by using the number of the following criteria: mean squared, root mean Square, mean absolute, and relative mean squared error values between the methods, namely  maximum likelihood and Bayesian estimators for the two parameters of the exponentiated exponential distribution. In estimating the maximum likelihood, The equations cannot be solved directly, Then Newton-Raphson method is used. Because of Bayes estimators under scale invariant squared and weighted composite linear-exponential loss functions the ratios cannot be simplified in a closed form. So, we use Lindley approximation. MATLAB program is used to display the results.
Inspection Times and Optimal Censoring Scheme for Generalized InvertedExponential Distribution with Progressive type I Interval Censored Data
Authors: Hasan Rana , Al-Mosawi Riyadh R. , Qader Abdullah Abdul
Published: April 2024

In this article, two issues related to the design of the experiment are investigated; namely the inspection times and optimal censoring. In the first issue, we study four different approaches to determine the inspection times, namely; pre-specified, equally spaced, optimally spaced, and equal probability using two optimality criteria. In the second issue, we identify the optimal censoring scheme by finding the expected numbers of removals or proportions that attain a specific optimality criterion using two optimality criteria considered. Numerical comparisons using the Monte Carlo simulations are provided of the inspection times, optimum control schemes issues for different parameters and different sample sizes. Statistical measures such as bias and root mean square error for both pre-specified and equal space methods are calculated and the inspection times for different values of the censoring percentage h are obtained.
Antioxidant Activity of New Tetrazole, Thiazolidin-4-one, and Aza-beta Lactam Linking to Secondary Imines of Imidazopyridine
Authors: Abdul Maged Abdul Gabar , AL-Lami Naeemah
Published: April 2024

In this contribution, new derivatives of bicyclic fused rings with a bridgehead nitrogen atom were synthesized from the imidazo[1,2-a]pyridine derivatives C1 by reacting two moles of 2-aminopyridine and 4-aminoacetophenone with iodine in a one-pot reaction. This compound (C1) was then condensed with 2-nitrobenzaldehyde and 2,4-dichlorobenzaldehyde to form new derivatives of Schiff bases (C2 and C3). These Schiff bases were then cyclized to synthesize thiazolidin-4-one derivatives (C4 and C5), tetrazole derivatives (C6 and C7), and aza-β-lactam derivatives (C8 and C9) through the reactions with thioglycolic acid, sodium azide, and 1-naphthylisocyanate, respectively. FT-IR, 1H NMR, and 13C NMR spectroscopy were used to characterize these new compounds. In the second part of this work, the antioxidants of these compounds were measured, and results ranged from good to medium.

Chronic Kidney Disease (CKD) has been raised as a public health state worldwide and is associated with increased cardiovascular morbidity and mortality. The aim of the study was to assess serum lipid profile levels, renal function and glucose in CKD patients undergoing hemodialysis. A total of 50 patients (23 males and 27 females) with CKD attending the hemodialysis at Kidney Unit in Al-Ramadi Teaching Hospital, Anbar Iraq and of ages ranging between 20 -85 years, were sustained for this research. The patients were classified into three categories with their mean age of 65.71±1.98 years. Eleven healthy adults were also recruited in this study with mean age of 37.00±15.56 years as control group. The study included measuring biochemical markers such as glucose, total cholesterol(TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C),  very-low-density lipoprotein (VLDL) , creatinine and urea by using automated chemistry analyzer by Abbott/USA. The outcomes of this study showed that the urea and creatinine levels increased significantly, whereas HDL-C level significantly decreased in the patients as compared with control group. However, TC and LDL-C showed slightly lower levels which were within the normal limits in the control group. While TG, VLDL and glucose levels showed non-significant changes in CKD patients as compared with control (P ≤ 0.05). In addition, all parameters revealed  no significant changes in males as compared with females group (P ≤ 0.05). Depending on age, only creatinine level showed significant change in 20-40 years age group as compared with 61-85years age group (p <0.05). Finally, abnormal lipid metabolism may probably be an independent risk factor for the progression of renal disease.
La Habana en el sistema de situados al Gran Caribe: una aproximación historiográfica (1530-1810)
Authors: Alfaro Velázquez Roide
Published: April 2024

El situado fue un mecanismo de financiación sin paralelo en otros modelos coloniales más allá del español. Si bien su génesis se ubica en el siglo XVI, es la centuria dieciochesca donde alcanza sus mayores índices de remisión hacia las zonas favorecidas, aquellas periferias del Imperio sin recursos para lograr su autogestión financiera, pero con una centralidad geopolítica que las convertían en “llaves del Nuevo Mundo”. El presente trabajo propone destacar los referentes historiográficos que se detienen en las relaciones financieras entre Nueva España y Cuba e invita a transgredir las fronteras geográficas del erario novohispano para resaltar el rol articulador y de equilibrio caribeño que jugó la villa de La Habana en la estrategia imperial española. De igual manera, insta a abrir aquellas puertas temáticas que aún permanecen en penumbras dentro de la multiplicidad de consecuencias que tuvieron estos envíos en metálico en las economías “nacionales” de las plazas militares caribeñas.

Este artículo es resultado del trabajo histórico y etnográfico realizado en torno al paisaje de la comunidad purhépecha de Carapan, Michoacán, México. El objetivo es recrear la percepción que tienen los habitantes de esta población acerca de elementos que componen su territorio y los elementos más prominentes de su paisaje desde una perspectiva simbólica. Se realiza un acercamiento con la comunidad, el registro de sus narrativas y sus actividades, buscando en estos datos los espacios que componen y caracterizan su territorio simbólico, espacios que son importantes para su identidad y que hacen parte del devenir histórico de este pueblo. Se busca entender cómo figuran los sitios arqueológicos, documentos históricos y el entorno natural dentro de los distintos discursos que aparecen en la comunidad. El resultado es un diagnóstico de identificación de espacios que componen la memoria del pueblo de Carapan, caracterizado por sus diferentes usos y desusos, la multiplicidad de voces y valores, integrándolos a partir del concepto de patrimonio.

La necesaria participación de profesores en la elaboración e instrumentación de reformas curriculares, de Enrique Peña Nieto a Andrés Manuel López Obrador (2012-2022)
Authors: Romo Rodríguez Paulina Araceli , Camacho Sandoval Salvador
Published: April 2024

Este artículo analiza el distanciamiento entre los docentes y las autoridades que diseñan reformas educativas. Primeramente, se analizan los cambios impulsados por el gobierno de Enrique Peña Nieto (2012-2018) y la consecuente reacción de las organizaciones sindicales, así como los resultados de un estudio realizado en escuelas de educación primaria del estado de Aguascalientes, México. Enseguida, se apuntan algunas medidas de la reforma educativa promovida por la administración gubernamental de Andrés Manuel López Obrador (2018-2024) y la opinión de autoridades educativas del mismo estado. Se concluye que las reformas educativas son objeto de polémica y de cuestionamientos respecto a su pertinencia y temporalidad porque parecen estar alejadas de la realidad educativa y se espera su remplazo por otras.
