Analisis Relasi Parameter Pemotongan Baja St 43 Pada Mesin Bubut Gdw Lz 350

The aim of this research is to find out the correlations among cutting parameters, namely depth of cutting t(mm), cutting speed v (mm/min) and feeding s (mm/rev) of a steel St 43 on. Type of the lathe is GDW LZ 350.This research used experiment method.Data analysis results the below equation: t = (2,483 − 0,3936 ln V + 5,44 V − 0,863 V ln V ) e

Efektifitas Kolektor Energi Surya Pada Konfigurasi Paralel Serpentine

This study aims to demonstrate the effectiveness of the collector on the fluid mass flow rate variations in sunlight collectors on the configuration of the combined \u27parallel-serpentine\u27. Value of the mass flow rate is 0.09, 0.18 and 0.36 ltr/min. Fluid drained from the reservoir of cold water through the collector pipe and into the parallel configuration serpentine configuration and then stored in the hot water tank. The test results showed that the efficiency of a mass flow rate achieved at the optimum 0.36 liter / min. This result is probably leading to suitable for domestic purposes

Renal replacement therapy in acute kidney injury: controversy and consensus

Renal replacement therapies (RRTs) represent a cornerstone in the management of severe acute kidney injury. This area of intensive care and nephrology has undergone significant improvement and evolution in recent years. Continuous RRTs have been a major focus of new technological and treatment strategies. RRT is being used increasingly in the intensive care unit, not only for renal indications but also for other organ-supportive strategies. Several aspects related to RRT are now well established, but others remain controversial. In this review, we review the available RRT modalities, covering technical and clinical aspects. We discuss several controversial issues, provide some practical recommendations, and where possible suggest a research agenda for the future

Design Improvement of A Pneumatic Piston Using Design for Assembly (Dfa) Method, A Case Study

Teknik desain assembly (DFA) sudah lama dan sering digunakan pada industry untuk meningkatkan kualitas, mengurangi biaya, dan memperpendek waktu siklus proses manufaktur dari komponen dan produk. Paper ini bertujuan untukmeningkatkan efisiensi dari piston pneumatic dengan mendesain ulang masing-masing komponen produk dalamhubungannya dengan waktu handling, inserting dan assembling. Dengan kata lain, beberapa modifikasi termasuksejumlah komponen, pergantian material, dan waktu assembly. Efisiensi dari komponen produk yang dibuat meningkat secara signifikan dari 25,9% ke 67,45%. Efisiensi komponen tersebut meningkat dengan kenaikan hampir 50 % yang menghasilkan sisi ekonomi produk di pasaran

Errors in patient specimen collection: application of statistical process control.

BACKGROUND: Errors in the collection and labeling of blood samples for pretransfusion testing increase the risk of transfusion-associated patient morbidity and mortality. Statistical process control (SPC) is a recognized method to monitor the performance of a critical process. An easy-to-use SPC method was tested to determine its feasibility as a tool for monitoring quality in transfusion medicine. STUDY DESIGN AND METHODS: SPC control charts were adapted to a spreadsheet presentation. Data tabulating the frequency of mislabeled and miscollected blood samples from 10 hospitals in five countries from 2004 to 2006 were used to demonstrate the method. Control charts were produced to monitor process stability. RESULTS: The participating hospitals found the SPC spreadsheet very suitable to monitor the performance of the sample labeling and collection and applied SPC charts to suit their specific needs. One hospital monitored subcategories of sample error in detail. A large hospital monitored the number of wrong-blood-in-tube (WBIT) events. Four smaller-sized facilities, each following the same policy for sample collection, combined their data on WBIT samples into a single control chart. One hospital used the control chart to monitor the effect of an educational intervention. CONCLUSION: A simple SPC method is described that can monitor the process of sample collection and labeling in any hospital. SPC could be applied to other critical steps in the transfusion processes as a tool for biovigilance and could be used to develop regional or national performance standards for pretransfusion sample collection.
