The effects of soil physical properties on yield components, grape quality and grapevine yield cv. Cabernet Sauvignon in Ultic Palexeralf soils located in Central Southern Chile were assessed. The experimental design was completely randomized with three treatments of soil texture: clayey, sandy clay and clayey loam. The higher yield was obtained in the sandy clay and clayey loam soils. The increase of bulk density, penetration resistance and clay content decreased the number of clusters per vine, number of berries per cluster and grapevine yield. Soil texture had not effects on the yield of shoots, berry diameter and total acidity. However, soluble solids were higher in the clayey soil. Shoot orientation only had positive effects on the cluster weight, number of berries per cluster, and grapevine yield, being higher in the upward shoots. This research remarked the importance of soil physical properties on the selection of sites with viticultural aptitude.

Several authors have commented on the anatomical changes following radical prostatectomy(RP)for prostate cancer and their characteristic radiological appearances.1,2 Most of these relate to periurethral fibrosis and its clinical significance in patients with postprostatectomy sphincter weakness incontinence.3,4 On magnetic resonance imaging(MRI),this postsurgical fibrosis appears as a focus of low-signal intensity in the periurethral tissues at and around the level of the vesicourethral anastomosis(VUA)which is appreciable on both T1-and T2-weighted images.

Piwi-interacting RNAs(piRNAs of 26-32 nt in length)regulate gene expression,epigenetics,and transcriptional and post-transcriptional processes.1 In humans,piRNAs are expressed in germline and somatic tissues,and generally have a uracil at the 5'-end(position+1),an adenine at the+10 position,and are 2'-0 methylated at the 3'-end.2 Onice piRNAs form the RNA-induced silencing complex(RISC)with PIWl proteins,they serve as guides to find their complementary sequences of the target mRNA,thus initiating their *** Wuhan patient's genome is approximately 265 nucleotides(nts)in its 3'-UTR;piRNAs-like sequences have been reported in this region.3 Our objective was to search,through bioinformatics,for mRNA sequences that were homologous to the reverse complementary of the previously reported piRNA-like sequences from the 3'-UTR of SARS-Cov-2,3 and identify the possible interaction between them.

The trend towards miniaturization has increased dramatically over the last decade, especially within the fields concerned with bioengineering, microelectronics, and aerospace. Micromillin8 is among the principal manu- facturing processes which have allowed the development of components possessing micrometric dimensions, being used to the manufacture of both forming tools and the final product. The aim of this work is to present the principal aspects related to this technology, with emphasis on the work material requirements, tool ma- terials and geometry, cutting forces and temperature, quality of the finished product, process modelling and monitoring and machine tool requirements. It can be noticed that size effect possesses a relevant role with regard to the selection of both work material （grain size） and tooling （edge radius）. Low forces and temper- ature are recorded during micromillin8, however, the specific cutting force may reach high values because of the ploughing effect observed as the uncut chip thickness is reduced. Finally, burr formation is the principal concern with regard to the quality of the finished part.

Bilayer graphene with a twist angle O between the layers generates a superlattice structure known as a Moir6 pattern. This superlattice provides a O-dependent q wavevector that activates phonons in the interior of the Brillouin zone. Here we show that this superlattice-induced Raman scattering can be used to probe the phonon dispersion in twisted bilayer graphene （tBLG）. The effect reported here is different from the widely studied double-resonance in graphene-related materials in many aspects, and despite the absence of stacking order in tBLG, layer breathing vibrations （namely ZO＇ phonons） are observed.

In this manuscript the authors have studied gigantomastia in female workers. After this weight loss, they perform mammary reduction and, after a year, the patients were referred to the bariatric team. All patients stayed for one year at the Obesity Workshop to learn about the dangers and benefits of weight loss, breast reduction and the possibilities of a more healthy body and future repairing plastics. After all these procedures, they observe an adequate psychological preparation. The patients felt more comfortable and happy with the smaller breasts, operated by using the Resende technique.
