Analysis of Fibrous Compounds Using a Pressurized and Non-pressurized Conditions

High cell density cultivation of recombinant yeasts and bacteria under non-pressurized and pressurized conditions in stirred tank bioreactors.

This study demonstrates the applicability of pressurized stirred tank bioreactors for oxygen transfer enhancement in aerobic cultivation processes. The specific power input and the reactor pressure was employed as process variable. As model organism Escherichia coli, Arxula adeninivorans, Saccharomyces cerevisiae and Corynebacterium glutamicum were cultivated to high cell densities. By applying...

Performance Evaluation and Economic Analysis of Minimum Quantity Lubrication with Pressurized/Non-Pressurized Air and Nanofluid Mixture

Abstract—Water miscible cutting fluids are conventionally used to lubricate and cool the machining zone. But issues related to health hazards, maintenance and disposal costs have limited their usage, leading to application of Minimum Quantity Lubrication (MQL). To increase the effectiveness of MQL, nanocutting fluids are proposed. In the present work, water miscible nanographite cutting fluids ...

Compositional Differences of Ojeok-san (Wuji-san) Decoctions Using Pressurized or Non-pressurized Methods for Variable Extraction Times

This study compared Ojeok-san (Wuji-san in Chinese) decoctions produced using different extraction methods for variable times. Decoctions were extracted in pressurized or non-pressurized conditions for 60, 120, and 180 mins. We investigated the Ojeok-san extract yield, the total soluble solid content, the hydrogen ion concentration (pH), and the reference compound content. The extract yield and...

Caring for Pressurized Tissues

زخم های فشاری، یکی از عوارض ناخواسته درمانی بوده و اکثراً با درک هوشیاری و مراقبت بموقع قابل پیشگیری است. امروزه زخم های فشاری یا زخم بستر یکی از مسائل بغرنج درمانی محسوب می شود و این مسئله تا حد زیادی مربوط به این واقعیت است که، تعداد بسیاری از بیماران سالخورده از بیماری های جدی و حاد جان سالم بدر برده ولی به علت سالخوردگی و پاتولوژی عوامل چندگانه بیشتر در معرض ابتلاء به زخم های بستر می باشند.
