    Exchange bias-like magnetic properties in Sr2LuRuO6

    Full text link
    Exchange bias properties are observed in a double perovskite compound, Sr2LuRuO6. The observed exchange bias properties have been analyzed on the basis of some of the available theoretical models. Detailed magnetization measurements show that the exchange bias properties are associated with the Dzyaloshinsky-Moria (D-M) interaction among the antiferromagnetically ordered Ru moments (TN~32K). In addition to the usual canting of the antiferromagnetic moments, D-M interaction in this compound also causes a magnetization reversal at T~26K, which seems to trigger the exchange bias properties. Heat capacity measurements confirm the two magnetic anomalies.Comment: 5 Pages, 6 Figure

    In this work, the different cellulosic materials, namely cellulose and lignin are analyzed. In addition, the starch-containing matrices (isolated starch and flour) reinforced with cellulosic materials to be used in packaging applications are described. Many efforts have been exerted to develop biopackaging based on renewable polymers, since these could reduce the environmental impact caused by petrochemical resources. Special attention has had the starch as macromolecule for forming biodegradable packaging. For these reasons, shall also be subject of this review the effect of each type of cellulosic material on the starch-containing matrix-based thermoplastic materials. In this manner, this review contains a description of films based on starch-containing matrices and biocomposites, and then has a review of cellulosic material-based fillers. In the same way, this review contains an analysis of the works carried out on starch-containing matrices reinforced with cellulose and lignin. Finally, the manufacturing processes of starch/cellulose composites are provided as well as the conclusions and the outlook for future works.Fil: Gutiérrez Carmona, Tomy José.

    OVERVIEW OF SIDE EFFECTS OF HORMONAL CONTRACEPTION IN HEALTH COLOMADU 2 KARANGANYAR By: Tomy Perkasa ABSTRACT Background :Family planning acceptors using hormonal contraception within a certain time often complain of health problems, one of the health problems that are often experienced by the acceptor CICs is hypertension, or high-pressure virgin. Purpose :The purpose of this study is to analyze the picture of the side effects of hormonal contraceptives in health centers Colomadu 2 Karanganyar. The results are expected are expected to contribute concepts and theories related to side effects of hormonal contraceptive use. Method :This research uses descriptive quantitative method. Population and sample in this study are all women who have married and the use of hormonal contraceptives and recorded in Puskesmas Colomadu 2 Karanganyar totaling 119 people composed of 38 people using contraceptive injections, 42 people use contraception implat, 32 people use pills and 7 people Hormonal IUD contraceptive use. The sampling technique used is total sampling. Analysis of the data used in this study were univariate analyzes each variable that research to produce a frequency distribution and percentage of each variable. Result :The results showed that the injectable contraceptive users recorded in Puskesmas Colomadu 2 Karanganyar experience side effects on menstrual disorders (amenorrhea). Implant contraceptive users recorded in Puskesmas Colomadu 2 Karanganyar experience side effects amenorrhea. Users pills recorded in Puskesmas Colomadu 2 Karanganyar experience side effects of weight gain. Hormonal contraceptive IUD users recorded in Puskesmas Colomadu 2 Karanganyar experience side effects of pain / pain. Keywords: contraception, hormonal side effect

    Gizi buruk merupakan salah satu bentuk penyimpangan dan kelainan tumbuh kembang anak dapat terjadi apabila terdapat hambatan atau gangguan pada proses yang dipengaruhi oleh faktor genetika dan lingkungan. Kasus gizi buruk yang meningkat dan sangat ramai dibicarakan sejak ditemukan di NTB, telah membuka mata kita tentang masalah gizi anak balita. Kenyataan di lapangan, setelah NTB, hampir seluruh daerah di Indonesia segera melaporkan adanya kasus gizi buruk di wilayahnya. Fenomena ini kemungkinan berkaitan dengan pengalokasian dana yang digulirkan oleh pemerintah (Pusat) untuk penanggulangan kasus gizi buruk. Dengan kemajuan dan Perkembangan teknologi saat ini maka dibuatlah sistem penentuan status gizi pada anak serta perhitungan kalori yang dibutuhkan bagi penderita. Pada metode, digunakan algoritma fuzzy untuk menentukan status gizi yang tepat yaitu dengan perhitungan metode fuzzy sugeno serta perhitungan status gizi dengan perhitungan antropometri. Dengan adanya proyek akhir maka dihasilkan sebuah aplikasi untuk menentukan status gizi pada balita sehingga dapat mempermudah masyarakat dalam memantau status gizi pada anak serta tidak mengeluarkan biaya mahal untuk membeli obat maupun pergi ke Rumah Sakit untuk berkonsultasi tentang status gizi pada balita dan kalori yang dibutuhkan. Kata Kunci : Status gizi, Gizi Buruk, Fuzz
