Rotating detonation engines (RDEs) have been actively researched around the world for application to next-generation aerospace propulsion systems because detonation combustion has theoretically higher thermal efficiency than conventional combustion. Moreover, because cylindrical RDEs have simpler combustors, further miniaturization of conventional combustors is expected. Therefore, in this study, with the aim of applying RDEs to space propulsion systems, a cylindrical RDE with a converging–diverging nozzle was manufactured; the combustor length [Formula: see text] was changed to 0, 10, 30, 50, and 200 mm; and the thrust performance and combustion mode with the different combustor lengths were compared. As a result, four combustion modes were confirmed. Detonation combustion occurred with a combustor length of [Formula: see text]: that is, a converging rotating detonation engine. The thrust performance of this engine was 94 to 100% of the theoretical rocket thrust performance, which is equivalent to the thrust performance of conventional rocket combustion generated at [Formula: see text]. This study shows that detonation combustion can significantly reduce engine weight while maintaining thrust performance.

Objetivo: Analisar as características da Anorexia Nervosa (AN) e da Bulimia Nervosa (BN). Revisão bibliográfica: A BN é caracterizada por episódios de comer compulsivo associado a uma sensação de falta de controle comendo demais durante o episódio. Esses episódios são tipicamente seguidos de culpa e vergonha, que desencadeiam comportamentos compensatórios para evitar o ganho de peso. A AN é distinta como uma condição de auto-inanição, em que as pessoas estão abaixo do peso e se envolvem em comportamentos para evitar o ganho de peso. Estes distúrbios se relacionam a uma série de parâmetros socioculturais, fatores familiares, afeto negativo, baixa autoestima e insatisfação corporal. Considerações finais: A anorexia nervosa e a bulimia são os principais transtornos alimentares, nas quais os indivíduos mais afetados do sexo feminino. Os dois distúrbios tem um alto prejuízo, afetando o funcionamento social, psicológico e ocupacional de uma pessoa de tal forma que seu impacto pode persistir muito além do próprio transtorno. O tratamento de primeira linha para ambas as condições é a terapia cognitivo-comportamental, além disso, para a bulimia há uma opção farmacológica, a fluoxetina.
Symbioses between Green Marketing Sustainability and Competition Law in Malaysia
Authors: Ramaiah Angayar Kanni , Hussein Safinaz Mohd 
Published: February 2023

Purpose: The urgency to control and reduce environmental disasters to the air and water as well as plastic pollution, acute deforestation, industrial waste, chemical spills, climate change and global warming calamity has triggered the universal Sustainable Development Goals (SDG) policy. Thus, diverting the attention of every level of human activity towards attaining a ‘sustainable’ environment. This universal war against such environmental disasters has developed a reason to incorporate SDG policy goals into the Competition Law and Policy (CLP) globally. This exploratory study aimed to determine the symbiosis between the competition law and United Nations (UN), SDG policy application under Competition Act 2010 for promoting and enhancing Green Marketing (GM) in Malaysia.
Methodology: The study examines viable options for competition regulators to address sustainability policy for green marketing (GM) benefits under the scope of CLP. The study applies qualitative analysis by way of comparative study to the European Union (EU) approach to determine GM marketing legitimacy for acclaiming SDG policy as a criterion within the exemption proviso in the Competition Act 2010, Malaysia.
Findings: Competition Law can support GM sustainability initiatives to improve the environment since GM is not just about producing and marketing environmentally sustainable products but from a broader perspective contributes to innovation and consumer welfare. Hence, GM's social market and societal benefits towards sustainability objectives are arguably considered to outweigh its countervailing anticompetitive effects for sustainable exemption policy under the CLP. However, GM can only substantially contribute to addressing global warming and the environment under the SDG if applied legitimately. In addition, the GM must be also endorsed to incorporate broader environmental-related benefit policy within its competition law prohibition and exemption framework to resonate with the UN’s SDG.
Implications/Originality/Value: The endorsement of GM sustainable benefits by way of exemption, exception or being pro-competitive allows a fair competitive advantage for GM industry growth. The research examines and proposes the exemption options for GM-related mergers, a collaboration by way of agreement and government exception policies under CA2010.

ABSTRAK

Premenstrual Syndrome was an increase in emotional tension and it was a factor that usually starts one week to a few days before the onset of menstruation and disappears after menstruation comes, although sometimes it continued until menstruation stops. Premenstrual Syndrome was influenced by several factors, including nutritional status. From this observation, it was found that there are still many women who experience Premenstrual Syndrome (60%). This study aims to analyse the relationship between the nutritional status of female16-18 years with the incidence of premenstrual syndrome in Sooko Village - Mojokerto.
This study used observational analytical research methods. With a population of 50 and a sample of 40 respondents using simple random sampling, data obtained from young women who experienced and did not experience Premenstrual Syndrome were processed by frequency tabulation and then analysed by contingency coefficient test using SPSS.
Based on the results of the study, it was found that 23 students (57.5%) had Premenstrual Syndrome with normal nutritional status, while 11 students with underweight nutritional status, of which 9 students (27.5%) had premenstrual syndrome. Then from the results of the Contingency Coefficient Test, it is known that there is a relationship between the nutritional status of female16-18 years old with the incidence of premenstrual syndrome with a value of sig = 0.000. So it can be concluded that students who have underweight nutritional status have the most premenstrual syndrome and will reduce or disappear by improving nutritional intake in a balanced manner. Meanwhile, those who have normal nutritional status also continue to experience Premenstrual Syndrome because their age 16-18 years old is included in the age category of high risk of developing Premenstrual Syndrome.
From the results of the research above, it is expected to be able to develop conceptual insight in providing Health Education to young women so that they do not experience severe premenstrual syndrome.
