Decision tree-based approach to extrapolate life cycle inventory data of manufacturing processes.

Life cycle assessment (LCA) plays a crucial role in green manufacturing to uncover the critical aspects for alleviating the environmental burdens due to manufacturing processes. However, the scarcity of life cycle inventory (LCI) data for the manufacturing processes is a considerable challenge. This paper proposes a novel approach to extrapolate LCI data of manufacturing processes.

A methodology for energy dissipation prediction of the bolt group with non-uniform preload.

The bolted joints exhibit typical nonlinear hysteresis under tangential loading, and the deviations of the preload in the bolt group add to the complexity of the model describing this behavior. In this paper, based on the mechanical analysis of the bolt group, a new methodology for predicting hysteresis behavior under non-uniform preload was proposed. Firstly, based on the moment equilibrium within the framework of material mechanics and the tangential stiffness model of the joint interface, a new coordination equation of displacement and force between the bolted joints was deduced, which could realize the calculation of the bolt group loading curve.

Characterization of the Volatile Compounds in Seed Oil from Different Geographic Origins.

Volatile flavor of edible oils is an important quality index and factor affecting consumer choice. The purpose of this investigation was to characterize virgin seed oil (VCO) samples from different locations in southern China in terms of their volatile compounds to show the classification of VCO with respect to geography. Different samples from 20 producing VCO regions were collected in 2020 growing season, at almost the same maturity stage, and processed under the same conditions.

The Effect of Cake Polysaccharides on Growth Performance, Carcass Traits, Meat Quality, Blood Profile, and Caecum Microorganisms in Yellow Broilers.

The study was carried out to evaluate the influence of polysaccharides from oleifera cake (CCP) in Lingnan yellow broilers diet from 1 to 50 days. Growth performance, carcass traits, meat quality, blood profile, and caecum microorganisms were characterized by three different levels of 0, 200 and 800 mg/kg CCP supplementation. Dietary treatment did not affect the productive trait from 1 to 50 days of age, except that average daily feed intake decreased at 42 days of age ( < 0.

Rapid Determination of the Oil and Moisture Contents in Camellia gauchowensis Chang and Camellia semiserrata Chi Seeds Kernels by Near-infrared Reflectance Spectroscopy.

A fast and effective determination method of different species of vegetable seeds oil is vital in the plant oil industry. The near-infrared reflectance spectroscopy (NIRS) method was developed in this study to analyze the oil and moisture contents of Chang and Chi seeds kernels. Calibration and validation models were established using principal component analysis (PCA) and partial least squares (PLS) regression methods.

Hyperhomocysteinemia-induced upper extremity deep vein thrombosis and pulmonary embolism in a patient with methyltetrahydrofolate reductase mutation: a case report and literature review.

The study highlights pulmonary embolism and deep vein thrombosis by methylene tetrahydrofolate reductase (MTHFR) deficiency-related hyperhomocysteinemia occurring in rare locations of left veins superior to the heart extensively. A 59-year-old white man with history of leg pain, smoking, weight loss, benign prostatic hyperplasia, lipoma and panic attack presented with shortness of breath and chest pain for 2 days precipitated by not feeling well for months. The diagnostic workup revealed pulmonary embolism and deep vein thrombosis in the left subclavian vein which extended throughout the left brachiocephalic vein to the superior vena cava and left jugular vein.

Serum parathyroid hormone as a potential novel biomarker of coronary heart disease.

Objective: This study aimed to evaluate the relationships between serum parathyroid hormone (PTH) and coronary heart disease (CHD).

Methods: From July 2011 to February 2013, a total of 79 CHD patients and 94 normal control patients with ages ranging from 25 to 79 years were included in this study. Serum PTH level and common risk factors of CHD (age, gender, cholesterol, glycosylated hemoglobin [HbA1c], blood pressure [BP], history of diabetes, smoking, and body mass index) were investigated.
