Transformacja Polskiego Związku Łowieckiego w świetle ewolucji modelu łowiectwa w Polsce
2020
The Polish Hunting Association is a nationwide organization of Polish hunters and hunting clubs, whose traditions date back to the interwar period. This study presents the genesis and evolution of the Polish Hunting Association, which, in the wake of social and political changes in the country, has been transformed from a voluntary association into a monopolistic and compulsory-membership organization, which is to carry out tasks commissioned by public authorities. Additionally, as a result of further amendments, the Association has been transformed into a governmental agency, organizationally subordinated to the minister of the environment also in the scope of appointing its high-rank staf…
SUNCT/SUNA in Pediatric Age: A Review of Pathophysiology and Therapeutic Options
2021
The International Classification of Headache Disorders, 3rd edition (ICHD3) defines Short-lasting Unilateral Neuralgiform Headache Attacks (SUNHA) as attacks of moderate or severe, strictly unilateral head pain lasting from seconds to minutes, occurring at least once a day and usually associated with prominent lacrimation and redness of the ipsilateral eye. Two subtypes of SUNHA are identified: Short-lasting Unilateral Neuralgiform headache attacks with Conjunctival injection and Tearing (SUNCT) and Short-lasting Unilateral Neuralgiform headache attacks with cranial Autonomic symptoms (SUNA). These pathologies are infrequent in children and difficult to diagnose. The authors reviewed the ex…
Modular Paradigm for Composites: Modeling Hydrothermal Degradation of Glass Fibers
2021
Fiber-reinforced composite materials are often used in structural applications in humid, marine, and offshore environments. Superior mechanical properties are compromised by environmental ageing and hydrolytic degradation. Glass fibers are the most broadly used type of fiber reinforcement to date. However, they are also most severely affected by environmental degradation. The glass fiber degradation rates depend on: (1) glass formulation; (2) environmental factors: pH, T, stress; (3) sizing; (4) matrix polymer; (5) fiber orientation and composite layup. In this short review (communication), seven modules within the Modular Paradigm are reviewed and systematized. These modeling tools, encomp…
Hydrothermal Ageing Effect on Reinforcement Efficiency of Nanofibrillated Cellulose/Biobased Poly(butylene succinate) Composites
2022
Nanofibrillated cellulose (NFC) is a sustainable functional nanomaterial known for its high strength, stiffness, and biocompatibility. It has become a key building block for the next-generation of lightweight, advanced materials for applications such as consumer products, biomedical, energy storage, coatings, construction, and automotive. Tunable and predictable durability under environmental impact is required for high performance applications. Bio-based poly (butylene succinate) (PBS) composites containing up to 50% NFC content were designed and aged in distilled water or at high relative humidity (RH98%). PBS/NFC composites are characterized by up to 10-fold increased water absorption ca…
Advanced Composites and Applications: Book of abstracts
2023
The section ‘Advanced Composites and Applications’ was organized by the Institute for Mechanics of Materials of the University of Latvia (LU MMI) on 16.02.2023 as a part of the annual 81th scientific conference of the University of Latvia. It was organized remotely in Zoom. The official language of the section was English. The duration of the presentation was 10 minutes. The section was devoted to the discussion of the recent results within following topics: structure and properties of polymers and polymer-based composites, long-term properties, creep, and environmental ageing, composites for advanced applications, mechanical aspects of technology, and multifunctional properties.
SINDROME DI DOWN E SPORT: L'attività motoria per il recupero delle funzioni cognitive in età evolutiva
Contesto: Questo lavoro ha esaminato l'efficacia di un programma di allenamento integrato (allenatore e famiglia) in tre bambini con sindrome di Down, per migliorare le loro abilità motorie e cognitive, in particolare il tempo di reazione e la memoria di lavoro. Metodi: Il programma di allenamento integrato è stato utilizzato in tre bambini, due ragazzi (M1, con una età cronologica di 10,3 anni e di età mentale di 4,7 anni; M2, con una età cronologica di 14,6 anni e l'età mentale di meno di 4 anni) e una ragazza (F1, età cronologica 14,0 anni e un'età mentale di meno di 4 anni). Risultati: miglioramenti nei punteggi delle capacità motorie sono stati visti dopo il periodo di formazione. Magg…
Risk Factors, Lifestyle and Prevention among Adolescents with Idiopathic Juvenile Scoliosis: A Cross Sectional Study in Eleven First-Grade Secondary …
2021
Adolescent idiopathic scoliosis (AIS) has an incidence of 2–3% in the general population and a multifactorial etiology. The present study aims to analyze modifiable risk factors and their interactions in the development of AIS in order to increase knowledge about the disease and to prevent the evolution of AIS in young students with tailored public health strategies. A cross-sectional study was conducted over two consecutive school years among students attending 11 first-grade secondary schools in the province of Palermo, Italy. A self-administered questionnaire that investigated socio-demographical, physical and anamnestic characteristics and habits, focusing on possible risk factors…
National guidelines for dental diagnostic imaging in the developmental age
2019
This document aims to support the dental professional in choosing the adequate diagnostic technique, minimising the radiation dose in observance of the As Low As Reasonably Achievable (ALARA) principle (7). This principle states that the biological cost can only be justifed when the beneft, that is, the diagnosis, outweighs the risk related to radiation exposure. In this guideline paper, we report recommendations for radiologists, medical physicists, paediatrician, dentists and maxillofacial surgeons, with reference to the specifc felds.
Environmental Effects on Mechanical, Thermophysical and Electrical Properties of Epoxy Resin Filled with Carbon Nanofillers
2019
The aim of this work was to establish the effect of environmental factors (moisture and temperature) on some mechanical, electrical and thermal properties of epoxy-based composites filled with carbon nanofillers: nanotubes (CNT), nanofibers (CNF) and hybrid nanofiller (nanotubes/nanofibers in the ratio 1:1) and to reveal the most environmentally stable NC. First, the nanocomposites (NC) containing different nanofiller contents were prepared to evaluate electrical percolation threshold and to choose NC at certain electrical conductivity for further characterization of the physical properties in initial state and during/after environmental ageing. The environmental ageing consisted of water a…
