New powder reuse schema in laser-based powder bed fusion of polymers.

The laser-based powder bed fusion of polymers (PBF-LB/P) process often utilizes a blend of powders with varying degrees of degradation. Specifically, for polyamide 12, the traditional reuse schema involves mixing post-processed powder with virgin powder at a predetermined ratio before reintroducing it to the process. Given that only about 15% of the powder is utilized in part production, and powders are refreshed in equal proportions, there arises a challenge with the incremental accumulation of material across build cycles.

Currently, there are no guidelines on vitamin D supplementation devoted solely to cancer patients. The primary objective of the study was to evaluate the frequency of vitamin D deficiency in Caucasian cancer patients and to characterize the clinical factors that predispose individuals to decreased vitamin D concentration.

Effects of fetal number on acute phase proteins, cortisol, and hematological parameters in ewes during the periparturient period.

Many subclinical diseases associated with inflammation occur in sheep during the periparturient period. Clinical symptoms are usually detected at an advanced stage of the disease; therefore, there are considerable risks of permanent health disorders in fetuses or dams. Determination of acute phase proteins (APPs) as markers of inflammation may allow for an earlier diagnosis and effective treatment.

Chicken embryo as a model in epigenetic research.

Epigenetics is defined as the study of changes in gene function that are mitotically or meiotically heritable and do not lead to a change in DNA sequence. Epigenetic modifications are important mechanisms that fine tune the expression of genes in response to extracellular signals and environmental changes. In vertebrates, crucial epigenetic reprogramming events occur during early embryogenesis and germ cell development.

Field study on the factors affecting egg weight loss, early embryonic mortality, hatchability, and chick mortality with the use of classification tree technique.

The aim of this research was to study the factors affecting hatchability, percentage of egg weight loss during incubation, early embryonic mortality, and chick mortality in the first seven days of life in the field. This study was performed on 20,817,600 hatching eggs originating from 7 different breeder flocks. The factors responsible for variability of investigated traits were the following: genotype (ROSS 308, ROSS PM3), hen age (25 to 30, 31 to 45, 46 to 50, and 51 to 60 wk), egg storage time (0 to 13 d), and setter and hatcher type (Digital, Airstreamer, Vision, Focus, Biostreamer), which were determined using the classification tree technique.
