Reliability of one repetition maximum measurement for leg extension using an improved leg extension machine by Yoshikiyo Kanada, Hiroaki Sakurai, Yoshito Sugiura, Tomoaki Arai, Soichiro Koyama, Shigeo Tanabe

“…A ratchet was welded to the knee rotation axis of the leg extension machine to prevent counter rotation due to the free fall of weights. The 1RM measurement for knee extension was performed before and after machine improvement to observe changes in their reliability using the intra-class correlation coefficient (ICC). …”

Maternal high-fat diet during pregnancy or lactation changes the somatic and neurological development of the offspring by Cristiano Mendes-da-Silva, Catherine Ássuka Giriko, Laís Vales Mennitti, Lilian Fazion Hosoume, Tayane dos Santos Souto, Alexandre Valotta da Silva

“…Offspring of dams fed a HFD showed reduced weight and body growth, delayed physical maturation, and delayed maturation of the physiological reflexes, such as vibrissa placing, auditory startle response, and free-fall righting. Our findings suggest that maternal HFD during pregnancy or lactation modifies somatic and neurological development of the offspring, possibly increasing the risk of neuroendocrine and neuropsychiatric disorders later in life.…”

Stationar spherical-symmetric configuration of dark matter by M. Abishev, N. Beissen, B. Karsimanov, I. Uspanov, M. O. Alimkulova

“…The article is devoted to the consideration of a model problem, where mass flow of dark matter which take as only gravitational interacting spherical continuous medium without pressure and with radial opposite motion with equilibrium ascending and descending components, starting free fall from boundary of the sphere and passing through the center, stopping and fall back at the boundary of the spherical mass distribution, which give us stationary spherical-symmetric configuration of dark matter. …”

Eksplorasi Etnomatematika pada Permainan Tradisional Bekles by Priyatna Hendriawan, Siti Faridah

“…In addition, it can also be used as a problem in learning physics about the material of upper vertical motion and free fall motion. Based on the research results, it is known that the potential for ethnomathematics development in traditional bekles games is very large, which can be used as materials, teaching materials, or learning media such as student worksheets (LKPD).…”

Engaging Students of Senior High School in Simulation Development by Katerina GLEZOU, Maria GRIGORIADOU

“…We implemented the cross-thematic educational scenario ``Free fall simulation development'' as an open and flexible framework for activities in actual classroom circumstances, exploring two alternate instructional strategies: a) simulation development from scratch and b) use of a preconstructed microworld, and we observed how the students collaborate and interact with the programming environment. …”

Convergent processing of both positive and negative motivational signals by the VTA dopamine neuronal populations. by Dong V Wang, Joe Z Tsien

“…Using multi-tetrode recording, we find that up to 89% of the putative dopamine neurons in the VTA exhibit significant activation in response to the conditioned tone that predict food reward, while the same dopamine neuron population also respond to the fearful experiences such as free fall and shake events. The majority of these VTA putative dopamine neurons exhibit suppression and offset-rebound excitation, whereas ∼25% of the recorded putative dopamine neurons show excitation by the fearful events. …”

El ordenador en trabajos prácticos : Análisis de una experiencia en el aula de Física de Educación Secundaria by José Miguel Ayensa, Luis Rosado, Mª Luz Los Arcos

“…In the experimental design of practical work takes part the computer as a means of experimental data acquisitíon of speed and weights time that slide in a surface without rubbing and in free fall. The analysis of the results obtained with two experimental groups, as compared to other two control groups in a Secondary Education Center, índicates that the accomplishment of laboratory experiences, designed in the practical projects where takes part the computer, is capable of contributing to the significant learning in Elemental Dynamics more than by other traditional means. …”
