Renovation and Expansion of Casa Vila Mariana / entre escalas

Archdaily.com 

Located in Vila Mariana, São Paulo, the townhouse had already undergone some recent transformations. In addition to the joining of two semi-detached houses to fulfill a home-studio program for a young artist, the previous renovation included structural reinforcements and improvements to the kitchen, bathrooms and laundry room.

Knowing the learning strategy is not enough to use it: Example in reading strategies for Japanese undergraduates

Plos.org 

by Tsuyoshi Yamaguchi

Learning strategies are an important component of self-regulated learning. Learners are expected to use multiple strategies appropriately. This study focused on metacognitive knowledge in the use of learning strategies and attempted to clarify the hierarchical nature of multiple knowledge. Furthermore, the study provided suggestions that could lead to further efficient acquisition of learning strategies. Responses were obtained from 184 Japanese university students regarding the degree of strategy use... Читать дальше...

Molecular dynamics simulations of human α-defensin 5 (HD5) crossing gram-negative bacterial membrane

Plos.org 

by Tadsanee Awang, Phoom Chairatana, Prapasiri Pongprayoon

Human α-defensin 5 (HD5) is a cationic antimicrobial peptide exhibiting a wide range of antimicrobial activities. It plays an important role in mucosal immunity of the small intestine. HD5 exerts its bactericidal activities through multiple mechanisms, one of which involves HD5 inducing the formation of pores in the bacterial membrane, subsequently allowing the peptide to enter the bacterial cytoplasm. Nevertheless, the precise molecular... Читать дальше...



Effect of gait types and external weight carrying strategies on the femoral neck strains during stair descent

Plos.org 

by Chen Deng, Jason C. Gillette, Timothy R. Derrick

Gait and weight carrying method may change the femoral neck load during stair descent. Applying specific gait and weight carrying methods may reduce the femoral neck load during stair descent, which may reduce hip pain, hip pain related falls and fall related fractures for the older population. The purpose of this study was to test the effect of different gait types (step-over-step v.s. step-by-step) and external weight carrying strategies... Читать дальше...

Transcriptome-wide profiling of acute stress induced changes in ribosome occupancy level using external standards

Plos.org 

by Annie W. Shieh, Sandeep K. Bansal, Zhen Zuo, Sidney H. Wang

Acute cellular stress is known to induce a global reduction in mRNA translation through suppression of cap dependent translation. Selective translation in response to acute stress has been shown to play important roles in regulating the stress response. However, accurately profiling translational changes transcriptome-wide in response to acute cellular stress has been challenging. Commonly used data normalization methods operate... Читать дальше...

An efficient 3-approximation algorithm for the Steiner tree problem with the minimum number of Steiner points and bounded edge length

Plos.org 

by Donghoon Shin, Sunghee Choi

We present improved algorithms for the Steiner tree problem with the minimum number of Steiner points and bounded edge length. Given n terminal points in a 2D Euclidean plane and an edge length bound, the problem asks to construct a spanning tree of n terminal points with minimal Steiner points such that every edge length of the spanning tree is within the given bound. This problem is known to be NP-hard and has practical applications such as relay node placements in wireless networks... Читать дальше...

Heavy-tailed distributions of confirmed COVID-19 cases and deaths in spatiotemporal space

Plos.org 

by Peng Liu, Yanyan Zheng

This paper conducts a systematic statistical analysis of the characteristics of the geographical empirical distributions for the numbers of both cumulative and daily confirmed COVID-19 cases and deaths at county, city, and state levels over a time span from January 2020 to June 2022. The mathematical heavy-tailed distributions can be used for fitting the empirical distributions observed in different temporal stages and geographical scales. The estimations of the...

A growing threat: Investigating the high incidence of benzimidazole fungicides resistance in Iranian Botrytis cinerea isolates

Plos.org 

by Mohamad Mobasher Amini, Soheila Mirzaei, Ahmad Heidari

Effective management of fungicide application programs requires monitoring the profile of resistant populations of Botrytis cinerea, given its high-risk nature. This research aimed to examine the sensitivity of 200 B. cinerea isolates collected from different plant species and regions across Iran towards thiophanate-methyl and carbendazim fungicides. To distinguish between susceptible and resistant isolates, the discriminatory dose assay was employed... Читать дальше...

Individual-differences affecting emotion regulation behaviors of injured athletes: A retrospective quantitative study

Plos.org 

by Tomonori Tatsumi

Suppressing the expression of negative emotions caused by injuries prevents athletes from fully accepting their sports injuries. However, acceptance is maintained and promoted when positive reappraisal and suppression are synchronized. This study analyzes individual-differences affecting the use of these two emotion regulation behaviors. A questionnaire consisting of personal variables regarding athletic identity, commitment to sports ethics and emotion regulation behavior... Читать дальше...

Simulation of gravity- and pump-driven perfusion techniques for measuring outflow facility of ex vivo and in vivo eyes

Plos.org 

by Youssef Mohamed, Christopher L. Passaglia

Aqueous humor dynamics are commonly assessed by infusing fluid into the eye and measuring intraocular pressure (IOP). From the pressure-flow relationship, conventional outflow facility is estimated to study glaucomatous processes that lower facility or identify therapeutics that enhance facility in hopes of restoring healthy IOP levels. The relative merits and limitations of constant flow (CF), gravity-driven constant pressure (CPg), and pump-driven... Читать дальше...

Adaptive evidence of mitochondrial genes in Pteromalidae and Eulophidae (Hymenoptera: Chalcidoidea)

Plos.org 

by Ning Kang, Hongying Hu

Pteromalidae and Eulophidae are predominant and abundant taxa within Chalcidoidea (Hymenoptera: Apocrita). These taxa are found in diverse ecosystems, ranging from basin deserts (200 m) to alpine grasslands (4500 m). Mitochondria, cellular powerhouses responsible for energy production via oxidative phosphorylation, are sensitive to various environmental factors such as extreme cold, hypoxia, and intense ultraviolet radiation characteristic of alpine regions. Whether... Читать дальше...

Controlled synchronization of a vibrating screen driven by two motors based on improved sliding mode controlling method

Plos.org 

by Lei Jia, Guohui Wang, Cheng Pan, Ziliang Liu, Xin Zhang

With a requirement of miniaturization in modern vibrating screens, the vibration synchronization method can no longer meet the process demand, so the controlled synchronization method is introduced in the vibrating screen to achieve zero phase error state and realize the purpose of increasing the amplitude. In this article, the controlled synchronization of a vibrating screen driven by two motors based on improved sliding mode controlling method is investigated. Читать дальше...
