PHYSICAL CULTURE AS A SOCIAL CULTURAL PHENOMENON

open access: yesЗдоровье человека, теория и методика физической культуры и спорта, 2019
В статье раскрывается понятие физической культуры как особого вида культуры, представляющего собой, с одной стороны, специфический процесс, направлен-ный на формирование физической готовности человека к жизни, с другой стороны, — ре-зультат человеческой деятельности, средство и способ физического ...

Plasma‐Treated Hydrogel for Combined RONS and Chemotherapy Delivery: A Proof‐of‐Concept In Ovo

open access: yesAdvanced Functional Materials, EarlyView.
This study explores plasma‐treated hydrogels (PTH) as a new way to deliver both reactive oxygen and nitrogen species and chemotherapy (Doxorubicin) directly to tumors. In ovo tests show effects after a single dose, especially in osteosarcoma tumors. Tumor weight decrease, and a resistance‐related protein is reduced.

MnI‐Functionalized Covalent Organic Framework as Efficient Electrocatalyst for CO2 Reduction in a Catholyte‐Free Zero‐Gap Electrolyzer

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates the successful integration of a phenanthroline‐based 2D COF with MnI catalytic sites into a catholyte‐free membrane‐electrode‐assembly cell for CO2 electroreduction. The crystalline COF actively suppresses Mn⁰–Mn⁰ dimerization, achieving a turnover frequency of 617 h⁻¹ at 2.8 V (full‐cell potential), and enabling stable operation.

Consensual Violence: A Cultural Contradiction

open access: yes, 2015
In American culture, violence is typically understood as inherently negative; no one would want to be personally subjected to violence because violence by its very nature is undesirable. Thus, the idea of seeking out violence seems paradoxical.

Evolving Platinum‐Copper Nanostructures for Enhanced Photothermal Therapy and Controlled Copper Release in Cancer Therapy

open access: yesAdvanced Functional Materials, EarlyView.
Platinum‐Copper bimetallic nanoparticles may evolve depending on their synthesis under tumor microenvironment conditions and play a dual role as chemotherapeutic agents after releasing Cu ions and as near infrared photothermal agents with the Pt‐rich remaining frames.
