COMPARISON OF POMELO (

Warangkana MAKKUMRAI, Yue HUANG, Qiang XU

Frontiers of Agricultural Science and Engineering Pages 335-352 doi: 10.15302/J-FASE-2021391

Abstract: Pomelo is a member of the genus that is a key contributor to the breeding of modern citrus cultivars. China is the largest producer of pomelo and one of the top five pomelo exporting countries. Pomelos from Thailand are also well-known for their excellent quality and flavor and are ranked in the top ten export countries. This review introduces pomelo planting locations and conditions in China and Thailand. The characteristics and qualities of some commercial pomelo cultivars in China and Thailand are summarized to introduce them to international consumers and to document their similarities and dissimilarities. Data on bioactive compounds and antioxidant capacity are also included for most Chinese and Thai pomelos to highlight how they differ in this aspect because consumers are increasingly interested in healthier foods. In addition, the sensory perception in terms of aroma, flavor, texture and taste attributes, consumer perspective and preferences are discussed.

A comparison of production system life cycle models

Rajesh ATTRI, Sandeep GROVER

Frontiers of Mechanical Engineering 2012, Volume 7, Issue 3, Pages 305-311 doi: 10.1007/s11465-012-0332-5

Abstract:

Companies today need to keep up with the rapidly changing market conditions to stay competitive. The main issues in this paper are related to a company’s market and its competitors. The prediction of market behavior is helpful for a manufacturing enterprise to build efficient production systems. However, these predictions are usually not reliable. A production system is required to adapt to changing markets, but such requirement entails higher cost. Hence, analyzing different life cycle models of the production system is necessary. In this paper, different life cycle models of the production system are compared to evaluate the distinctive features and the limitations of each model. Furthermore, the difference between product life cycle and production life cycle is summarized, and the effect of product life cycle on production life cycle is explained. Finally, a production system life cycle model, along with key activities to be performed in each stage, is proposed specifically for the manufacturing sector.

Retrospective study of the efficacy and complication of thoracoabdominal incision for nephrectomy: a comparison

Minggen YANG, Xiaokun ZHAO

Frontiers of Medicine 2009, Volume 3, Issue 2, Pages 191-196 doi: 10.1007/s11684-009-0026-5

Abstract: This retrospective study was performed to compare the outcome of thoracoabdominal incision flank incision for radical nephrectomy in the patients with large renal tumors. A questionnaire assessing postoperative pain, administration of pain medications and the return to activities and work was sent to the patients who undergoing radical nephrectomy through the 11th rib (group 1: underwent flank incision, including 96 patients) or the 9th to 10th rib (group 2: undergoing thoracoabdominal incision, including 98 patients) from 2003 to 2007 in our hospital. A case retrospective analysis assessing operation time, perioperative hemorrhage volume, size of tumor, success in the treatment of tumor thrombus in renal vein or vena cava, time length of presence of drainage tube, postoperative analgesia usage and length of stay was conducted in patients whose questionnaires were returned. A total of 56 patients (58%) in group 1 and 60 (61%) in group 2 responded to the questionnaire. Time lengths of operation and presence of abdominal drainage tube were shorter in group 2 than those in group 1. Perioperative hemorrhage volume in group 2 was obviously less than that in group 1. The mean size of tumors in group 1 was significantly smaller than that in group 2 ( < 0.0005). The success rate of treating thrombus in renal vein or vena cava in group 2 was significantly higher than that in group 1 ( <0.05). Lengths of off-bed time and stay were the same in both groups. There were no differences between groups in terms of pain severity on postoperative day 1, on day of discharge and 1 month postoperatively ( >0.05). There were no significant differences between groups in the time following surgery when pain completely disappeared, when pain medications were discontinued, and when the patient returned to daily activities and work ( >0.05). The thoracoabdominal incision provides excellent exposure and allows for early vascular control. Efficacy and complication was comparable for thoracoabdominal and flank incisions in terms of incisional pain, analgesic requirements after discharge and return to normal activities.

Characterization and comparison of organic functional groups effects on electrolyte performance for vanadium

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 9, Pages 1221-1230 doi: 10.1007/s11705-023-2298-8

Abstract: The vanadium redox flow battery with a safe and capacity-controllable large-scale energy storage system offers a new method for the sustainability. In this case, acetic acid, methane sulfonic acid, sulfonic acid, amino methane sulfonic acid, and taurine are used to overcome the low electrolyte energy density and stability limitations, as well as to investigate the effects of various organic functional groups on the vanadium redox flow battery. When compared to the pristine electrolyte (0.22 Ah, 5.0 Wh·L^–1, 85.0%), the results show that taurine has the advantage of maintaining vanadium ion concentrations, discharge capacity (1.43 Ah), energy density (33.9 Wh·L^–1), and energy efficiency (90.5%) even after several cycles. The acetic acid electrolyte is more conducive to the low-temperature stability of the V(II) electrolyte (177 h at −25 °C) than pristine (82 h at −2 °C). The –SO₃H group, specifically the coaction of the –NH₂ and –SO₃H groups, improves electrolyte stability. The –NH₂ and –COOH additive groups improved conductivity and electrochemical activity.
