Quality improvement helps companies increase sales and reduce costs, both of which can increase profitability. PP Sinar Tani Palembang is a manufacturing industry engaged in rice milling. Quality control is still very lacking, this is indicated by the data from the scales which entirely pass the prescribed standards of 5 Kg, 10 Kg and 20 Kg. defective products: for 5 Kg packaged rice as much as 0.585 or 58.5%, 10 Kg rice as much as 0.604 or 60.4% and 20 Kg rice as much as 0.612 or 61.2%. It can be seen from the percentage of PP Sinar Tani Palembang every month experiencing a loss of 21,363 Kg or 1,068 kg per day with a nominal value of Rp 228,390.00 per month. By using the Six Sigmamethod, it is found that there are 2 factors that cause this loss is the occurrence of excess when filling and the balance scales of shear/oil scales used do not have accuracy so that the results of the scales all exceed the specified limit. One proposal that can be done is to replace the balance scales/shear scales/oil scales with digital scales so that the measuring results are more accurate. There was a decrease in the percentage of defects, namely for the weight of 5 kg from 0.585 to 0.166; weight of 10 kg from 0.604 to 0.145; weight of 20 kg from 0.612 to 0.139. Whereas from DPMO the increase from 2 sigma to 3 sigma.

Nutmeg oil, also known as essential oil, is an oil extracted from the seeds or leaves of nutmeg through a distillation process. Nutmeg oil has several advantages, including as an antibacterial ingredient, an additive in the perfume industry, and as a raw material for medicines in the pharmaceutical industry. In this study, the essential oil from nutmeg leaves was produced using the steam-water distillation method, where the nutmeg leaves were dried before the steam-water distillation process was carried out. As a fixed variable, 150 g of bulk cooking oil and 150 g of bimoli cooking oil were used, while as a variable, steam-water distillation temperature was used with temperature variations of 105 oC, 115 oC, and 125 oC. Samples of 1 mL, 2 mL, 3 mL, and 4 mL of nutmeg leaf oil were mixed with bulk cooking oil to compare the free fatty acid oxidation ability and peroxide value after 1 day, 3 days, 5 days, and 7 days. Analysis of the compound content of nutmeg leaf oil, free fatty acids, peroxide number, and antioxidant activity was carried out using GC-MS and 0.004% DPPH. The production of nutmeg leaf oil was obtained as much as 91 ml by steam distillation at a maximum temperature of 125 oC. Using a DPPH of 0.004 percent and a quantitative measure of IC50, the optimal antioxidant activity at 125 oC was found to be 2.03 percent. A comparison of free fatty acid numbers and peroxide values found in this study revealed that pure bimoli cooking oil had the lowest free fatty acid and peroxide values.

Estudio preliminar de la aplicación de la técnica VMAT en irradiación corporal total: diseño de una camilla rotable
Authors: Pinzón C. Andrés , Simbaqueba Axel , Rodríguez Juan , Veloza Stella , Esguerra C. José
Published: November 2022

La irradiación corporal total (TBI, por sus siglas en inglés) es una terapia previa al trasplante de médula ósea en la que se administra una dosis de radiación uniforme en todo el cuerpo del paciente, que busca minimizar la dosis  entregada en diferentes órganos como pulmones y, en algunas ocasiones, riñones [1]. En Colombia la TBI con rayos X generados por acelerador lineal se realiza con la técnica convencional, en la cual el paciente mantiene una posición anatómica de pie, fetal o decúbito lateral durante tiempos de irradiación prolongados, lo cual implica que la posición de tratamiento para el paciente sea incómoda y poco reproducible; adicionalmente su implementación requiere distancias fuente/paciente de hasta 4 metros y la construcción de protecciones personalizadas [2]. Con el fin de superar estas dificultades, el Instituto Nacional de Cancerología (INC) tiene el objetivo de desarrollar un protocolo para administrar la TBI empleando arcoterapia volumétrica de intensidad modulada (VMAT). Con esta técnica de optimización inversa se ha reportado una  entrega de dosis de radiación más uniforme en todo el cuerpo del paciente en comparación con la técnica convencional, y una reducción de la dosis recibida por los órganos en riesgo (OAR) [3]; adicionalmente su implementación no requiere grandes áreas en la sala de tratamiento, ya que se realiza a distancias estándar fuente/isocentro. En este artículo se presenta un estudio preliminar del protocolo de TBI/VMAT y su validación, mediante el empleo de un simulador anatómico CIRS: la construcción de una camilla rotable para ser  superpuesta a la mesa del acelerador y tomógrafo, que facilita el cambio de orientación craneocaudal del paciente a caudocraneal durante el tratamiento, recomendaciones para la inmovilización del paciente sobre la camilla rotable, la obtención de imágenes de tomografía computarizada de cuerpo completo mediante fusión de imágenes parciales, la planeación del tratamiento con múltiples isocentros y múltiples arcos para el cálculo de la dosis absorbida y la verificación del tratamiento con superposiciones de medidas de dosis en el software SNC Patient tomadas con detectores en el dispositivo ArcCheck en diferentes orientaciones.

The utilization of used polystyrene as adhesive material for emulsion polymer asphalt has been carried out. Polystyrene foam was dissolved in toluene at the ratio of 30:70 mL, then the solution was mixed with aquadest at ratios of 90: 10 mL, 70: 30 mL, 50: 50 mL, 30:70 mL, and 10: 90 mL. Then added with 10 mL of Sodium Dodecyl Sulfate solution at concentrations of 10%, 20%, and 30%. The most stable latex polystyrene was mixed with 200 g of sand aggregate at volume ratios of 10 mL, 20 mL, 30 mL, 40 mL, and 50 mL. Then the mixture was pressed into a hotpress at 150ºC for 20 minutes. The mixture obtained was characterized using tensile strength testing, water absorption, and SEM spectroscopy. The results showed that the mixture of sand aggregate with 50 mL latex polystyrene has the best compressive strength and water absorption, at a load of 1606 Kg.f, a stroke of 14.93 mm/minutes, and a water absorption percentage of 18%. The morphology result showed that the surface of sand aggregate with 50 mL of latex polystyrene mixture contains smaller and least holes than the surface of sand aggregate with 10 mL of latex polystyrene mixture.

A tuberculose (TB) é uma doença transmissível considerada grave. A diferença de tempo entre a obtenção dos resultados da testagem de um paciente e o início do tratamento aumenta a chance de transmissão da tuberculose. O intento deste artigo foi verificar o número de casos confirmados de tuberculose no Brasil entre 2015 e 2019 segundo a região de notificação, faixa etária, forma da doença e situação de encerramento. Para tal realizou-se uma pesquisa de caráter qualitativo e quantitativo. Os dados quantitativos foram retirados do departamento de informática do Sistema Único de Saúde do Brasil (DATASUS). Regiões do país com maior IDH parecem lidar melhor com a transmissão, tratamento e cura da tuberculose. A população economicamente ativa, com maior exposição a outras pessoas são o grupo mais acometido devido ao tipo de transmissão. O tipo pulmonar da tuberculose acomete o maior número de pessoas devido a forma de transmissão via aérea e também a atuação do sistema imunológico do organismo, com o combate sendo mantido a nível cavitário. O alto índice de sucesso no tratamento (cura) reflete que existe real possibilidade de combate ao bacilo. Infelizmente a taxa de abandono demonstra o quão mal um desequilíbrio social pode fazer à saúde pública.

The nexus between uncertainty and foreign direct investment flows to G20 member countries
Authors: Daştan Muhammet , Karabulut Kerem , Yalçınkaya Ömer
Published: November 2022

The main objective of this study is to examine the link between global economic, political, and geopolitical uncertainties and FDI flows to G20 member countries over the 1996-2018 period. Unlike most of the previous studies, this study employs reasonable uncertainty indexes, namely, the Economic Policy Uncertainty (EPU) index, the World Uncertainty Index (WUI) for economic/political uncertainty rather than the volatility or election indicators. The study also uses the Geopolitical Risk index as a proxy for geopolitical uncertainty, and thereby it not only focuses on economic/political uncertainty but also considers the geopolitical uncertainty to provide a more comprehensive picture of uncertainty. Findings obtained from the panel data analysis indicate that heightened uncertainty in the global economic/political and geopolitical environment deters FDI flows to G20 member countries. It is also found that there is a unilateral causality running from uncertainty to FDI inflows. Considering these empirical findings, policymakers in G20 economies should provide a stable economic/political and geopolitical environment to attach FDI inflows, which have a key role in stimulating economic growth and development.
