Published: August 2023

Se obtuvieron películas delgadas electrocrómicas de níquel y óxido de empleándose la técnica de rociado pirolítico.
Las películas de óxido de níquel fueron obtenidas de dos formas. Una empleando soluciones alcohólicas de Ni(NO3)26H2O, y otra usando soluciones acuosas Ni(NO3)26H2O adicionando pequeñas cantidades de Co(NO3)26H2O. La temperatura de depósito para ambos casos fue de 300°C. Ambas muestran un electrocromismo pronunciado; particularmente en el segundo caso cuando la proporción Ni(NO3)2: Co(NO3)2 es de 90:10 se obtiene un cambio de la transmitancia de 50% en el rango visible.
Las películas de óxido de tungsteno-fósforo se obtuvieron a partir de un sol de WOx al cual se le añadió ácido fosfórico. El sol fue preparado por intercambio iónico de Na2WO4.2H2O en una resina fuertemente ácida. La temperatura de depósito fue de 430°C. Se observó un incremento significativo de la capacidad de carga del WOx a medida que se aumenta la proporción de P en la película.

Published: August 2023

El presente estudio teórico - experimental enfoca principalmente las particularidades de los procesos de trabajo de los motores diesel en los regímenes de cargas parciales y de vacío y, el método más simple y efectivo para mejorar estos parámetros de funcionamiento, especialmente el de los índices económicos. Este método, según lo demuestra nuestra investigación, es el de la regulación de la presión inicial del combustible en la línea de alta presión (LAP); desde la línea de alimentación (baja presión) y, mediante la válvula de regulación de la presión inicial (válvula RND, por su procedencia rusa).
Este sistema es muy interesante ya que es aplicable a los motores diesel, con sistema de inyección del tipo separado, que se encuentran actualmente en explotación y, prácticamente mantiene la estructura original del sistema de inyección de combustible. La aplicación de este sistema permite suministrar adicionalmente combustible en la LAP aprovechando el fenómeno hidrodinámico que se produce al final de cada inyección y así, intensificar los procesos de inyección y mejorar los procesos de pulverización, de formación de la mezcla y de la combustión.
Los ensayos experimentales se realizaron en el banco Cussons con motor Ricardo E6 del Instituto de Motores de Combustión Interna de la Universidad Nacional de Ingeniería. Mostraremos algunos resultados comparativos de la presente investigación.

Published: August 2023

Crystal guava (Psidium guajava var. 'Crystal') fruit is in great demand because of its delicious taste and high nutritional content. Storage aims to prevent postharvest damage to the fruit. However, storage that is too long causes morphological damage and decreased nutrients. This study aims to determine the effect of storage duration, fruit ripeness stage and the interaction between both factors on vitamin C and total soluble solids (TSS) content of crystal guava, and determine which treatment can produce the highest vitamin C and TSS. Fruits harvested simultaneously with three levels of ripeness based on the skin color: unripe fruit is dark green, ripe is light green, very ripe is yellowish green. Samples selected based on the same weight range. Storage was carried out for 0, 5, and 10 days at ± 10oC. The study used a completely randomized design (CRD) with a 3x3 factorial pattern with two factors: storage duration and fruit ripeness level. Parameters observed were vitamin C, TSS, weight loss, diameter shrinkage, skin color and hardness. Data were analyzed using ANOVA and DMRT. Both treatments showed an interaction on vitamin C content. The best treatment was unripe fruit stored for ten days with 14.955 ppm of vitamin C. Both treatments did not show any interaction on TSS content. The best treatment was five days storage with TSS of 8.25 °Brix and very ripe fruit of 8.21 °Brix. Based on vitamin C, TSS content, and physical condition variables, the best guava fruit is unripe fruit stored for 10 days.Keywords: color, postharvest, physical, quality, softening

T1 contrast versus fluid-attenuated inversion recovery contrast technique for evaluation of cerebral tuberculosis
Authors: Ramalingam Balavaitheeswar , Padmanaban Elamparidhi , Raj Joe Vimal , Sambath Pugazhendhi , Varadane Avinesh 
Published: August 2023

Objectives:
T2-weighted (T2W) fluid-attenuated inversion recovery (FLAIR), a traditional magnetic resonance imaging (MRI) technique, is regarded as one of the most effective methods for examining brain disorders. The identification of brain pathologies can be significantly aided by T2 FLAIR and T1 post-contrast imaging. However, lesion enhancement is occasionally inconspicuous on T1-weighted image. Hence, for the evaluation of brain disorders, a MRI approach known as FLAIR contrast would combine the benefits of T2W FLAIR with contrast-enhancement on a single picture.

Material and Methods:
After obtaining clearance from the Institution’s Ethics Committee, contrast-enhanced MRI (CE-MRI) brain of 20 patients was taken for the study. CE-MRI was performed using 1.5 Tesla Intera PHILIPS with intravenous administration of gadolinium at approximately 0.1 mL/kg/body at a rate of 10 mL/15 s.

Results:
This study showed a better appreciation of lesion conspicuity when compared to prior T1 contrast images. However, there was no significant difference in the number of lesions, lesion extension, and degree of contrast-enhancement on comparison with T1 contrast images.

Conclusion:
T1 FLAIR contrast shows a better appreciation of lesion conspicuity when compared to T1 contrast images. Post-contrast FLAIR imaging is a valuable adjunct to post-contrast T1W imaging and effectively delineates cerebral tubercular pathologies. However, T1 FLAIR cannot be used as a replacement for conventional T1 fat saturated post-contrast imaging.
Clenching exercise as additional orthodontic treatment in anterior open bite patients
Authors: Irmawati Anis , Devitha Maria , Balqis Noor Faizah , Azzaim Yassir Ahmad , Al-Mekhlafi Raed 
Published: August 2023

Background:
Anterior open bite is a complex case of malocclusion that needs complex treatment. This malocclusion has a tendency to relapse, so the difficulty level of treatment is high. Clenching exercise began to be applied as an additional myofunctional therapy that can help correct anterior open bite and stabilize treatment results.

Purpose:
This narrative review aims to explain clenching exercise as an additional orthodontic treatment in anterior open bite patients.

Review(s):
The most essential step in open bite treatment is the retention period because the tendency for relapse is strong and difficult to predict. Surgical treatment can be used to achieve an anterior open bite, but this treatment does not guarantee the stability of the treatment outcome. To achieve retention in anterior open bite correction, it is essential to improve muscle function after treatment.

Conclusion:
Clenching exercise can be an additional therapy in anterior open bite patients to shorten the treatment duration and maintain the stability of the treatment outcome.
The effect of paracetamol on the parasitological diagnosis of Plasmodium falciparum malaria
Authors: Magzob Mohamed , Sammani Ashraf Al , Siddiq Ahmed Al 
Published: August 2023

Objectives:
Up until the present time, malaria represents an immense public health problem worldwide with a significant morbidity and mortality rate in many developing countries including Sudan. The use of antipyretics and analgesics in the settings of malaria has been a matter of contention over a vast period of time. Now, it is widely believed among the public and some health professionals in Sudan that the antipyretic and analgesic paracetamol disturbs the accuracy of the parasitological diagnosis of malaria. This study investigates the magnitude and effects of that belief through a descriptive study and examines the actual effect of paracetamol on the parasitological diagnosis of falciparum malaria through a clinical trial.

Material and Methods:
This is a conjoined study that includes a prospective and descriptive study and a randomized, placebo-controlled, double-blind, and parallel-group clinical trial. The descriptive study included 846 participants from various states in Sudan. The targeted study subjects were the public and health professionals and the study was conducted utilizing an online-based questionnaire. The clinical trial included 325 patients with uncomplicated falciparum attending two primary healthcare outpatient clinics in Gezira state, Sudan. The patients were randomly allocated to receive either placebo tablets or 500 mg of oral paracetamol after the first blood smear sample was taken. The second blood smear samples were taken 2 h after taking treatment. Parasite density estimation and other parasitological data were obtained from each sample before and after treatment.

Results:
The majority of the public thinks that paracetamol affects the parasitological diagnosis of malaria (76.21%, n = 330/433). Personal experience and family and friends were the most dominant information sources for the public (31.20% and 28.01% respectively), while scholarly articles were the most common source of information for the health professional group (45.03%, n = 186/413). No significant differences between the parasitological findings acquired before and after taking the treatments among both the paracetamol group (P = 0.22) and the placebo group (P = 0.12). The parasite density mean for the paracetamol group differed by 16.31 P/μL after taking paracetamol, while the placebo group parasite density mean differed by 15.34 P/μL. The treatments did not inflict impacts on the advanced microscopic features of Plasmodium falciparum blood smears.

Conclusion:
Paracetamol does not affect the parasitological diagnosis of falciparum malaria.
Analysis of Surfactant and Polymer Behavior on Water/Oil Systems as Additives in Enhanced Oil Recovery (EOR) Technology through Molecular Dynamics Simulation: A Preliminary Study

Published: August 2023

The decline in oil production has led to the development of the Enhanced Oil Recovery (EOR) technology to increase oil production. Chemical injection is one of the methods in EOR by injecting surfactants or polymers into reservoir wells. To understand the properties and dynamics of surfactants and polymers at the nanoscale, computational studies using molecular dynamics simulation were carried out. In this study, surfactant Sodium Dodecyl Benzene Sulfonate (SDBS) and polymers such as Polyacrylamide (PAM) were used to investigate their effect on the oil-water interface system at the atomic level. Molecular dynamics simulation was carried out using Large-scale Atomic/Molecular Massively Parallel Simulator (LAMMPS) to calculate the diffusion coefficient and Interface Formation Energy (IFE) value for the addition of the surfactant and polymers. The simulation results show that the addition of the surfactant and polymers affects the water-oil interface system differently. The diffusion coefficient results indicates that there are strong interactions between SDBS and dodecane with D of 0.01358. While for PAM, the interactions with water are more significant with D of 0.059. The results of the IFE calculation value also show that the addition of SDBS and PAM makes the water-oil interface system more stable with the negative IFE value of -197.51 and -13.13 Kcal/mol respectively. The results of this study will be used as a reference and a basis for designing new surfactants or polymers that will led to more oil recovery.
