A modified procedure for dehydrative ketal protections is disclosed, which serves as an alternative to the classic Dean-Stark protocol. Studies show that this new procedure can outperform the Dean-Stark apparatus on small scales and thus serves as a complementary approach to effect dehydrative ketalizations. A detailed procedure for this apparatus is presented.

Multilevel support-assisted prototype optimization network for few-shot medical segmentation of lung lesions.
Sci Rep
January 2025
Shandong Provincial Public Health Clinical Center, Shandong University, Jinan, 250013, Shandong, China.
Medical image annotation is scarce and costly. Few-shot segmentation has been widely used in medical image from only a few annotated examples. However, its research on lesion segmentation for lung diseases is still limited, especially for pulmonary aspergillosis.

Scarce feature points are a critical limitation affecting the accuracy and stability of incremental structure from motion (SfM) in small-scale scenes. In this paper, we propose an incremental SfM method for small-scale scenes, combined with an auxiliary calibration plate. This approach increases the number of feature points in sparse regions, and we randomly generate feature points within those areas.

As a critical component of rocket systems, the grid fin is widely applied in the aerospace industry. Compared to traditional manufacturing methods and other additive manufacturing (AM) techniques, wire arc additive manufacturing (WAAM) is more advantageous in its time and cost efficiency, especially when it is utilized in the large-scale production of components. Given the significant effect of the welding strategies on the quality of manufactured parts, we investigated two distinct WAAM printing orientations, horizontal, or lie (L), and perpendicular, or stand (S), using a small-scale model.

Microorganisms
January 2025
Department of Molecular Sciences, Uppsala BioCentrum, Swedish University of Agricultural Sciences, P.O. Box 7051, 750 07 Uppsala, Sweden.
Cassava is an important staple food that contributes to the food security of small-scale Mozambican farmers. In southern Mozambique, cassava roots are usually processed into cassava roasted flour, locally known as "rale". The handling and processing practices connected to "rale" production may introduce microbial contamination.

Int Ophthalmol
January 2025
Department of Ophthalmology, Ege University Medical Faculty Hospital, Ege University, 35100, Bornova, Izmir, Turkey.
Purpose: To evaluate the severity distribution of chemical burn-induced Limbal stem cell deficiency (LSCD) according to the novel global consensus classification and to compare the treatment approach, before and after the global consensus.
Methods: Medical records of 127 eyes of 109 patients with LSCD were included. LSCD stages were categorized according to the global consensus classification published by "International LSCD Working Group".
