Eksplorasi Teknik Heat Transfer Printing dengan Zat Warna Dispersi pada Kain Sintetis

Seiring perkembangan jaman dan teknologi, perkembangan pada industri tekstil pun turut berkembang. Setelah tekstil sintetis berkembang di industri tekstil pada tahun 1920-an, teknik pengolahannya pun turut mengalami perkembangan dikarenakan tekstil sintetis memiliki sifat hydrophobic dan thermoplastic. Zat warna yang dirasa cocok untuk mewarnai tekstil sintetis adalah zat warna disperse yang berkembang pada awal tahun 1940. Kemudian ditemukan suatu teknik olah latar tekstil tersebut setelah beberapa percoban dengan zat warna disperse di tahun yang sama. Percobaan yang dilakukan didasari oleh sifat zat warna disperse yang ringan dan mudah tersublimasi jika terkena panas, didukung oleh sifat tekstil sintetis yang thermoplastic yaitu tenunannnya memiliki tendensi untuk meregang ketika terkena panas dan tekanan. Zat warna dispersi diwarnai diatas medium kertas yang kemudian diletakkan diatas kain sintetis kemudian diberikan perlakuan panas dan tekanan. Zat warna disperse yang tersublimasi akan berpindah dari kertas masuk ke pori-pori kain sintetis yang sedang meregang dan saat temperatur kembali pada suhu normal, struktur kain akan kembali ke sedia kala dan mengikat zat warna pada permukaan kain. Sehingga heat transfer printing menjadi salah satu teknik tekstil modern untuk reka latar kain sintetis

Pentingnya Pemeriksaan Hemoglobin Pada Ibu Hamil

Pregnancy is a physiological condition that is naturally experienced by women who are productive and fertile. During pregnancy, a mother must routinely perform Ante Natal Care (ANC) at least 4 times during pregnancy. The purpose of a mother doing ANC is to maintain the health of the mother and fetus and to prevent complications during pregnancy. One of the causes of complications in pregnant women is anemia due to iron deficiency which is a case that is often found in pregnant women. One indicator of anemia is to look at the picture of hemoglobin levels in pregnant women. One of the causes of anemia is due to iron deficiency which results from insufficient nutrition for pregnant women. The aim of this activity is to screen pregnant women suffering from anemia at RB Sinta and provide education to pregnant women regarding the importance of ANC during pregnancy. Method: This activity is carried out by checking Hb levels in pregnant women and providing counselin

"Now we are in a different time; various bad diseases have come." understanding men's acceptability of male circumcision for HIV prevention in a moderate prevalence setting

Background: Adult male surgical circumcision (MC) has been shown to reduce HIV acquisition in men and is recommended by the WHO for inclusion in comprehensive national HIV prevention programs in high prevalence settings. Only limited research to date has been conducted in countries experiencing moderate burden epidemics, where the acceptability, operational feasibility and potential epidemiological impact of MC remain unclear. Methods. A multi-method qualitative research study was conducted at four sites in Papua New Guinea (PNG), with 24 focus group discussions and 65 in-depth interviews carried out among 276 men. Results: The majority of men were in favour of MC being introduced for HIV prevention in PNG and considered improved genital hygiene, enhanced sexual pleasure and culturally appropriateness key factors in the acceptability of a future intervention. A minority of men were against the introduction of MC, primarily due to concerns regarding sexual risk compensation and that the intervention went against prevailing cultural and religious beliefs. Conclusion: This is one of the first community-based MC acceptability studies conducted in a moderate prevalence setting outside of Africa. Research findings from this study suggest that a future MC program for HIV prevention would be widely accepted by men in PNG

Malaria vector research and control in Haiti: a systematic review

BACKGROUND: Haiti has a set a target of eliminating malaria by 2020. However, information on malaria vector research in Haiti is not well known. This paper presents results from a systematic review of the literature on malaria vector research, bionomics and control in Haiti. METHODS: A systematic search of literature published in French, Spanish and English languages was conducted in 2015 using Pubmed (MEDLINE), Google Scholar, EMBASE, JSTOR WHOLIS and Web of Science databases as well other grey literature sources such as USAID, and PAHO. The following search terms were used: malaria, Haiti, Anopheles, and vector control. RESULTS: A total of 132 references were identified with 40 high quality references deemed relevant and included in this review. Six references dealt with mosquito distribution, seven with larval mosquito ecology, 16 with adult mosquito ecology, three with entomological indicators of malaria transmission, eight with insecticide resistance, one with sero-epidemiology and 16 with vector control. In the last 15 years (2000–2015), there have only been four published papers and three-scientific meeting abstracts on entomology for malaria in Haiti. Overall, the general literature on malaria vector research in Haiti is limited and dated. DISCUSSION: Entomological information generated from past studies in Haiti will contribute to the development of strategies to achieve malaria elimination on Hispaniola. However it is of paramount importance that malaria vector research in Haiti is updated to inform decision-making for vector control strategies in support of malaria elimination

Optimization as Side-Effect of Evolving Allelopathic Diversity

. Many bacteria carry gene complexes that code for a toxin-antidote pair, e.g. colicin systems. Such gene complexes can be advantageous for its host by killing competitor bacteria while the antidote protects the host. However, in order to evolve a novel and useful toxin first a proper antidote must be evolved. We present a model of bacteria that can express and evolve such allelopathic systems. Although in the model novel types must evolve from existing types we find that nevertheless in general a high diversity of toxins evolves and, as a sideeffect thereof, generalized immunity mechanisms. We interpret the allelopathic systems in terms of an optimization problem: fitness cases are toxins and solutions present (potential) antidotes. As a side-effect of the evolution of allelopathic systems generalized solutions of the optimization task are evolved as well. 1 Introduction Many bacteria, such as Escherichia Coli and related bacteria, carry colicin systems [7, 17]. Colicin systems are g..
