ABSTRACT

Yellow watermelon (Citrullus lanatus (Thunb.)) is a kind of horticulture commodity that contains high water content. There are three parts of yellow watermelon, namely the outer part (exocarp), the middle part with white color (mesocarp), and the fruit flesh (endocarp) that the mesocarp often becomes waste of the consumption of yellow watermelon. One of the development innovations for yellow watermelon is to process it into fermented beverage such as water kefir using the mesocarp so that there is no waste material. This research aims to know the effect of mesocarp concentration on yellow watermelon water kefir physicochemical and microbiology characteristics. The method of research was using Completely Randomized Design with one factor (mesocarp concentration). Treatment variation which is utilized the 0% (v/v), 5% (v/v), 10% (v/v), 15% (v/v), and 20% (v/v) of mesocarp concentration. The research results show that the higher mesocarp concentration can increase the total of lactic acid and lactic acid bacteria, decrease the alcohol content and total of yeast, contribute to give antioxidants on water kefir, and mesocarp concentration does not have a real impact on viscosity.

ABSTRACT

Watermelon is one of the fruits that are in abundance in the dry season, especially on the island of Lombok. This abundant availability sometimes makes watermelons become waste. One way to take advantage of unsold watermelons so that they do not have to become waste is to extract the antioxidant compounds found in watermelons. The antioxidant compound found in watermelon is lycopene. Lycopene is an antioxidant compound that has many benefits, especially in controlling free radicals in the body. Also, lycopene is useful for preventing cardiovascular disease, diabetes, and, cancer. Lycopene extraction in watermelon fruit waste was carried out by the liquid-liquid method, using Hexane and Ethanol as a solvent with a ratio of 2:1. The purpose of this study was to determine the lycopene content in watermelon waste based on the ratio of feed and solvents (F/S), as well as time and temperature. The ratio of F/S used is 1:1, 1:2, 1:3, 1:4, 1:5 extraction temperature (30, 40, 50, 60, 70, 80, and 90) o C while the time used (30, 40, 50, 60, 70, 80, 90, 100, 110, 120) minutes. Based on the analysis using UV-Vis Spectrophotometry, it is known that the optimum conditions for lycopene content are in the F/S ratio of 1:4 at 70oC and 90 minutes. The lycopene content obtained was 3, 1595 mg/100gram.

Medellín e os sinais dos tempos
Authors: Suess Paulo 
Published: February 2021

Desde a Encíclica Pacem in terris (1963) de João XXIII, o termo “sinais dos tempos” aponta para uma nova consciência histórica da Igreja. Medellín assume um compromisso histórico de libertação frente à realidade latino-americana de 1968. Esse compromisso se expressa através de uma maior aproximação aos pobres, de denúncias da violência social e de incentivos à conscientização e organização dos setores populares. Infelizmente, os pobres dos Documentos de Medellín ainda não têm rostos indígenas ou afro-americanos. A “opção pelos pobres”, de Medellín, necessita ser aprofundada através da “opção pelo protagonismo dos pobres e dos outros na própria Igreja”. Hoje, ao nos confrontarmos criticamente com a proposta de Medellín, afirmamos a importância do sonho que ele despertou: sonho de uma Igreja nova, “autenticamente pobre, missionário e pascal”.
Abstract: Ever since the Encyclical Pacem in terris (1963) by Pope John XXIII, the term “signs of the times” has pointed towards a new historical consciousness in the Church. Medellín assumed an historical compromise ofliberation in face of the reality of Latin America in 1968. This compromise is expressed through a greater approximation to the poor, through denoucements of social violence and incentives to the conscientization and organi- zation of the popular sectors. Unhappily, the poor of the Documents of Medellín still haven’t got Indian or Afro-American faces. The “option for the poor" of Medellín needs to be deepened through the “option for the protagonism ofthe poor and of the others in the Church itself”. Today, critically facing up to the proposal of Medellín, we affirm the importance of the dream that it awoke: the dream of a new Church, “authentically poor, missionary and paschal”.

Indomethacin is a nonsteroidal anti-inflammatory drugs (NSAIDs) that act to inhibit COX-1. The inhibition of COX-1 leads to inhibition of prostaglandin production. Prostaglandin is a regulator of gastric acid buffer secretion. Inhibition of prostaglandin decrease gastric and duodenum pH and damage the gastric and duodenum. Sea grapes (Caulerpa racemose var. cylindracea) are marcoalgae that contain flavonoids as antioxidants and anti-inflammatory. The aim of this study was to determine the effect of sea grapes on gastric and duodenum pH in rattus norvegicus induced by indomethacin. 32 male Rattus norvegicus were divided into 4 groups. Group K (-) without treatment. Group K (+) was induced by 30 mg/Kg BW indomethacin for 7 days. Group P1 was induced by 30mg/Kg BW indomethacin for 7 days followed by administration of 1g/100g BW sea grape extract for 14 days. Group P2 was induced by 30mg/Kg BW indomethacin for 7 days followed by administration of 2g/100g BW sea grape extract for 14 days. On the 29th day, rats were terminated, gastric and duodenal were isolated then the fluid pH was measured. One-way Anova test obtained p = 0,023. Post hoc test pH Gaster significantly different between group K (-) and K (+) (p= 0,005) and between group K (-) with P2 (p= 0,020). While in group K (+) with P1 and P2 there was no significant difference in pH. Post hoc test of pH duodenum showed no differences in all group.

Published: February 2021

This study is critically analyzed the relationship between policy and practices of decision making in public schools of Nepal. I tried to explore the relationship between policy and practicesin two districts of Kathmandu valley by using qualitative data using power and decentralization theoryand different decision-making models. I understood that parents, head teacher, and teachers apply decentralization cum power theory in decision making practices in schools. I also found that these authorities mainly take decisions in physical resource management, teacher recruitment, and program extension. I also came to understand that mixed- model approach is blended between head teacher, teacher and community control model. At the practicing level, I found gap in the use of power in various aspects of decision making. I also found that these gaps were observed because of practicing of head teacher control model. The study implies that decision making process at the school level needs a new model that must be more contextual and participatory for the effective school management.

Published: February 2021

Objectif : Les patients présentant des signes d’accident vasculaire cérébral (AVC) nécessitent une prise en charge rapide. En France, il a été mis en place une filière « neurovasculaire » dédiée à ces patients. L’objectif de cette étude était de décrire la filière de prise en charge des patients présentant des signes évocateurs d’AVC dans le système de soins français.
Méthodes : Étude prospective observationnelle de courte durée pendant trois jours dans 35 régulations Samu, 27 Smur et 85 services d’urgences en France, incluant tout patient de plus de 18 ans présentant un signe évocateur d’AVC ou d’accident ischémique transitoire (AIT). Les patients suivaient ou non la filière neurovasculaire définie au préalable.
Résultats : Du 29 novembre au 1er décembre 2016, 827 patients ont été inclus, d’âge moyen 68 ans. Parmi eux, 418 avaient un AVC confirmé, dont 231 accidents ischémiques constitués. La filière UNVa été suivie pour 279 patients (44 %). Le délai médian de prise en charge médicale était de 3 heures 49. Pour les patients avec AVC confirmé, ce délai était significativement plus court dans la filière neurovasculaire (2 heures 45 vs 5 heures 56 ; p < 0,001).
Conclusion : En France, la prise en charge dans une filière dédiée des patients suspects d’AVC n’est actuellement effective que dans la moitié des cas. Cette filière nécessite d’être promue.
