DIFERIMENTO ICMS CAVACO DE MADEIRA PARANÁ
Empresa optante pelo Simples Nacional (Paraná) vende cavaco de madeira (NCM 4401.22.00) para estabelecimento industrial, em operação interna, enquadrada no art. 30 c/c item 45 do art. 31 do Anexo VIII do RICMS/PR (diferimento do ICMS). A dúvida é exclusivamente operacional no PGDAS-D. 1. Como deve ser informada essa receita no PGDAS-D? 2. No campo "Tributação do ICMS", deve-se selecionar alguma opção (Exigibilidade Suspensa, Isenção/Redução, ST etc.) ou deixar sem seleção? 3.

1. Introduction Click to copy section linkSection link copied! Fracture healing is a highly orchestrated biological process involving the spatial and temporal regulation of genes and cell-signaling molecules and the synthesis of proteins. (1) Throughout this process, osteoblasts and osteoclasts act in a coordinated manner to achieve a balance between bone deposition and resorption, which is essential for restoring tissue integrity and mechanical stability at the injury site.
How I shipped 108 programmatic pages in 5 days and still ranked 74th
I'm Marcelo, a solo founder shipping AI micro-SaaS tropicalized for Brazil. Last month I generated 108 programmatic pages for Interior AI Brasil in 5 days. Most of them sit at average position 74 in Google Search Console, with page scores I thought would carry them further. This is the honest breakdown of why they don't rank. The short version: Domain Rating is a gatekeeper that page-level optimization cannot bypass in the short term. I knew this in theory.
How I built 8 micro-SaaS products in 4 months using programmatic SEO
I'm 21, studying software engineering in Brazil, and I've been building a portfolio of AI-powered micro-SaaS products by myself. No funding, no ads. Just SEO. Four months in, I have 8 live products, about 1,000 programmatic landing pages indexed, and $500 in monthly recurring revenue. Most of that comes from 2 products. The rest are basically experiments that haven't proven anything yet. Here's how the whole thing works.

Introduction Click to copy section linkSection link copied! In recent years, inorganic semiconductors have gained increased prominence in academia and industry by their potential to overcome the challenges of availability, high-cost processing, and toxicity, which have been insurmountable for the development of new technologies that enhance quality of life on a global scale.
Disentangling the structure, optical properties, and photoluminescence emissions of NiW1−xMoxO4 (x = 25, 50, and 75%) solid solutions: experimental and DFT studies
Disentangling the structure, optical properties, and photoluminescence emissions of NiW1−xMoxO4 (x = 25, 50, and 75%) solid solutions: experimental and DFT studies† Solid solutions, formed by combining two transition metal oxides with distinct properties, offer promising potential for optimizing functional characteristics that may be lacking in the parent materials.

Tuning the electronic properties of Zr UiO-66 through defect-functionalised multivariate modulation.
Tuning the electronic properties of Zr UiO-66 through defect-functionalised multivariate modulation. The multivariate modulation of Metal-Organic Frameworks is presented as a valuable tool to introduce multiple functional units into UiO-66 while increasing its porosity. This manuscript encloses a comprehensive study using p-functionalised -NO2, -SO3 and -SH modulators, rationalizing the defects introduced and their impact on properties.

Eco‐friendly Synthesis of Silver Nanoparticles and its Application in Hydrogen Photogeneration and Nanoplasmonic Biosensing
Abstract Environmentally friendly methods for silver nanoparticles (AgNPs) synthesis without the use of hazardous chemicals have recently drawn attention. In this work, AgNPs have been synthesized by microwave irradiation using only honey solutions or aqueous fresh pink radish extracts. The concentrations of honey, radish extract, AgNO3 and pH were varied. AgNPs presented mean sizes between 7.0 and 12.8 nm and were stable up to 120 days.
Carbon Black CB-EDA Nanoparticles in Macrophages: Changes in the Oxidative Stress Pathway and in Apoptosis Signaling
3. Results A,B shows the scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images of CB nanoparticles. Good granulometric homogeneity of the particles was observed, with their unitary diameters varying between 10 and 40 nm. The particles showed a highly aggregated irregular spheroid morphology.
High-Performance Macrotia Surgery
1. Introduction Macrotia is one of the causes of ear deformities although it is not as common as the protruding ear deformity. Exaggerated enlargement of the ears causes great discomfort for the patient, who may suffer from low self-esteem and bullying. According to Yuen [1], external proportions of the ears are divided into three sections: the upper third comprises 33% of the ear height, the middle third comprises 43%, and the lower third comprises 23%.
Performance-optimized otoplasty.
This study proposes a new surgical alternative for the most common deformity in the ears, the so-called “protruding/prominent ears”, which is a condition that affects 5% of the Caucasian population (Goulart et al. in Rev Bras Cir Plast 26:602-607, 2011). This technique comes with the benefits of reduced surgical time, shallow learning curve, and a low revision rate. We studied a total of 213 patients with an indication for otoplasty from January 2020 to January 2021.
