Review on power quality solution technology

This paper presents a comprehensive study of various possible solutions for power quality improvement in common applications and supply system. This includes improved power quality converters (IPQC), multi-pulse converters, active compensation, passive compensation and their hybrid configurations. Various configurations and topologies of custom power devices such as DSTATCOM (Distribution Static Compensator), DVR (Dynamic Voltage Restorer) and UPQC (Unified Power Quality Compensator) are also described in detail. Main applications of these devices are for reactive power compensation, harmonic elimination, voltage sag/swell mitigation, voltage regulation, load balancing, neutral current reduction etc. Many such cases of power quality problems have been taken up and suitable solutions have been identified for those cases. As an example, a model of DSTATCOM is developed and its performance is presented for a distribution system feeding nonlinear loads

Studi Perencanaan Sistem Pengelolaan Sampah Kota Kudus (Studi Kasus: Kecamatan Kota Kudus, Jawa Tengah)

Kecamatan Kota Kudus merupakan salah satukecamatan yang termasuk dalam wilayah pelayanan pengelolaan sampah Kabupaten Kudus. Secara umum pengelolaan sampah di Kecamatan Kota Kudus belum berjalan dengan baik, hal ini dapat dilihat pada tingkat pelayanan sampah yang hanya sebesar 50,60%. Berdasarkan hasil analisis, timbulan sampah perkapita yang dihasilkan adalah sebesar 2,71 l/orang/hari dan komposisi sampahnya sebesar 52,35% sampah organik dan 47,65% sampah anorganik. Perencanaan pengelolaan sampah di Kecamatan Kota Kudus difokuskan kepada sub sistem operasional yaitu penambahan infrastruktur dan pengelolaan sampah dengan konsep 3R. Sub sistem peraturan yang membuat dan menegakkan aturan tentang pengelolaan sampah, sub sistem kelembagaan yang mengoptimalisasi fungsi dari UPTD sebagai operator pengelolaan sampah, serta sub sistem pembiayaan yang mengatur pendanaan pengelolaan sampah dari APBD dan retribusi masyarakat. Sub sistem peran serta masyarakat berupa partisipasi dalam penanganan sampah dan mentaati peraturan yang ada. Pelaksanaan program 3R diharapkan dapat meningkatkan partisipasi masyarakat dalam mengelola sampah serta mengurangi jumlah sampah

PRESCRIPTION ANALYSIS, DRUG INTERACTION CHECKING AND IMPACT OF PATIENT COUNSELING BY A CLINICAL PHARMACIST IN TYPE II DIABETES MELLITUS PATIENTS IN A TERTIARY CARE HOSPITAL-A PROSPECTIVE STUDY

Objective: To evaluate the clinical pharmacist role in the prescription analysis, drug interaction and the impact of patient counseling in type 2 diabetes mellitus patients. Methods: A prospective study was conducted in 203 type II Diabetes Mellitus patients for a period of 6 mo in the Diabetology department. Prescriptions were analyzed and self-care assessment for good health practices were collected using a questionnaire and the adherence scores were calculated. Patient counseling was provided to the patient and a follow up was done using the same self care assessment questionnaire. Results: Out of 203 patients, 86 multiple therapy, 68 dual therapy and 49 monotherapy were observed. Glimepiride+Metformin (54), a combination of short acting and intermediate-acting insulin (41) was the most commonly prescribed drugs. Out of 1102 drugs, 488 were anti diabetic drugs, 35 were antibiotics, 579 were other drug classes prescribed. The drug interactions were reported. The adherence score shows a highly significant impact after counseling. Conclusion: The results of the current study helps to understand the changes in prescription pattern, drug interactions and the impact of patient counseling by a clinical pharmacist

Pengelolaan Sampah Rumahtangga Berbasis Komunitas: Teladan dari Dua Komunitas di Sleman dan Jakarta Selatan

Studi kasus pengelolaan sampah rumahtangga di Wedomartani (Sleman, Yogyakarta, Daerah Istimewa) dan Banjarsari (Jakarta Selatan) memberikan perspektif alternatif untuk meminimalisasi timbunan sampah yang dikelola oleh pemerintah melalui skenario daur ulang sampah dengan mengkombinasikan aspek teknis, ekologi, ekonomi, sosial budaya, kebijakan dan kelembagaan. Tujuan dari kajian ini adalah untuk mengetahui efektivitas dan efisiensi pengelolaan sampah rumahtangga dari sumbernya di Wedomartani dan Banjarsari; 2) untuk membuat sintesis pola pengelolaan sampah berbasis komunitas; 3) untuk menguji dan mengevaluasi efektivitas dan efisiensi pola dari kedua studi kasus tersebut. Penelitian ini dilakukan dari bulan Juni 2005 sampai Agustus 2006. Pengumpulan data dilakukan melalui wawancara, observasi, dan pengambilan sampel. Analisis data dilakukan secara deskriptif meliputi analisis efektivitas biaya, analisis regresi, analisis varian dan t-test. Pengelolaan sampah berbasis masyarakat memberikan beberapa keuntungan yakni : 1) mengurangi 57 persen sampah 70 persen dari total jumlah sampah; 2) efisiensi biaya sebesar 23 persen sampai 37 persen dibandingkan pengelolaan secara konvensional; 3) peningkatan nilai ekonomi dengan penjualan barang daur ulang, pelayanan pelatihan daur ulang dan bentuk-bentuk diversifikasi yang lain; 4) menciptakan harmoni sosial antar banyak pihak. Implementasi kedua pola ini di Bogor belum dapat dilakukan secara optimal karena belum terpenuhinya prasyarat untuk mencapainya. Tingkat biaya operasional juga belum dapat dicapai secara menguntungkan

Participation of Indian Women in Agricultural Sector: A Study Based On Rural Areas in India

Agriculture is the prime engine of growth and backbone of developing nations. In India, a developing economy, nearly 60% of the working population find agriculture as their main source of income/livelihood. Women play multiple roles in agriculture and allied activities such as food production, horticulture, harvesting operations, fisheries, etc. It is also estimated that in India about 75% of women are working as agricultural labour force and are active agents of the primary sector. The present study focuses on the nature and extent of female participation in Indian agriculture using secondary data on the period 1993-2012

Primary Hepatic Leiomyosarcoma Report of a rare case with review of literature

Primary hepatic leiomyosarcoma is an extremely rare tumor with a dismal prognosis and difficulty in diagnosis. We present a 36-year-old female who presented with complaints of pain in right hypochondrium and epigastric region. Real-time ultrasonography revealed an enlarged liver with multiple hypoechoic lesions of varying sizes in both the lobes of the liver. USG guided core biopsy from the lesion showed an infiltrating malignant spindle cell neoplasm positive for smooth muscle actin and caldesmon-H confirming the diagnosis of leiomyosarcoma. It is vital to diagnose these lesions even on limited biopsies as early diagnosis can reduce hospital and operative morbidity and mortality rates in the patients
