Physical resistance of the flexural joint in mortar Joints and clay blocks prisms

In buildings, each component contributes to resisting seismic forces and an important part in this activity are the masonry walls composed of: fired clay solid brick of 120 mm width and horizontally perforated clay blocks of 100 mm and 150 mm width. The main focus of this research is to determine the flexural strength of the horizontally perforated clay block-mortar joint, using different types of mortar as established in the “Reglamento Colombiano de Construcion Sismo Resistente” for four suppliers used in the municipality of Ocaña, Colombia. A semi-automatic machine that takes into account the physics in the application of loads was designed to carry out the flexural test in mortar-block joints. The average flexural strength in mortar-block joints was determined for three types of mortar corresponding to 0.219 MPa, 0.232 MPa, and 0.291 MPa respectively, for the municipality of Ocaña, Colombia. This research established a direct relationship between the compressive strength of the mortar and the flexural strength of the 100 mm wide horizontally perforated clay mortar-block joint. A physical comparison was made in terms of the compressive strength of the prism and the flexural strength of the clay mortar-block joint with that obtained by other researchers in India and found quite similar results.

Development of a Sulfate Resistance Performance Test for Concrete by Tensile Strength Measurements: Determination of Test Conditions

Assessing the sulfate resistance of concrete is essential for the use of concrete in sulfate rich environments. A multitude of test methods exists worldwide, showing the relevance of the problem and the difficulty to find a suitable test setup. Testing the relative tensile strength of ASTM C307 concrete briquette specimens after exposure to a sulfate solution is a new direct method to assess the degree of deterioration. The aim of this study is to develop a new performance test, which considers both the chemical and physical resistance of a specific concrete mix against sulfate attack. In the experimental investigations, the binder type, storage temperature, type and concentration of sulfate solution, and concrete composition were varied, and the remaining tensile strength evaluated to define the test parameters. To gain significantly distinguishable data within nine months of storage, the use of sodium sulfate solution with 6000 mg SO42−/l at 5 °C is proposed.

While offline iterations of the climate activism movement have spanned decades, today online involvement of youth through social media platforms has transformed the landscape of this social movement. Our research considers how youth climate activists utilize social media platforms to create and direct social movement communities towards greater collective action. Our project analyzes narrative framing and linguistic conventions to better understand how youth climate activists utilized Twitter to build community and mobilize followers around their movement. Our project identifies three emergent strategies, used by youth climate activists, that appear effective in engaging activist communities on Twitter. These strategies demonstrate the power of digital culture, and youth culture, in creating a collective identity within a diverse generation. This fusion of digital and physical resistance is an essential component of the youth climate activist strategy and may play a role in the future of emerging social movements.

Injectable Cryogels in Biomedicine

Cryogels are interconnected macroporous materials that are synthesized from a monomer solution at sub-zero temperatures. Cryogels, which are used in various applications in many research areas, are frequently used in biomedicine applications due to their excellent properties, such as biocompatibility, physical resistance and sensitivity. Cryogels can also be prepared in powder, column, bead, sphere, membrane, monolithic, and injectable forms. In this review, various examples of recent developments in biomedical applications of injectable cryogels, which are currently scarce in the literature, made from synthetic and natural polymers are discussed. In the present review, several biomedical applications of injectable cryogels, such as tissue engineering, drug delivery, therapeutic, therapy, cell transplantation, and immunotherapy, are emphasized.

Translational Modeling of Psychomotor Function in Normal and AD-Pathological Aging With Special Concerns on the Effects of Social Isolation

One year after the start of the COVID-19 pandemic, its secondary impacts can be globally observed. Some of them result from physical distancing and severe social contact restrictions by policies still imposed to stop the fast spread of new variants of this infectious disease. People with Alzheimer's disease (AD) and other dementias can also be significantly affected by the reduction of their activity programs, the loss of partners, and social isolation. Searching for the closest translational scenario, the increased mortality rates in male 3xTg-AD mice modeling advanced stages of the disease can provide a scenario of “naturalistic isolation.” Our most recent work has shown its impact worsening AD-cognitive and emotional profiles, AD-brain asymmetry, and eliciting hyperactivity and bizarre behaviors. Here, we further investigated the psychomotor function through six different psychomotor analysis in a set of 13-month-old 3xTg-AD mice and their non-transgenic counterparts with normal aging. The subgroup of male 3xTg-AD mice that lost their partners lived alone for the last 2–3 months after 10 months of social life. AD's functional limitations were shown as increased physical frailty phenotype, poor or deficient psychomotor performance, including bizarre behavior, in variables involving information processing and decision-making (exploratory activity and spontaneous gait), that worsened with isolation. Paradoxical muscular strength and better motor performance (endurance and learning) was shown in variables related to physical work and found enhanced by isolation, in agreement with the hyperactivity and the appearance of bizarre behaviors previously reported. Despite the isolation, a delayed appearance of motor deficits related to physical resistance and tolerance to exercise was found in the 3xTg-AD mice, probably because of the interplay of hyperactivity and mortality/survivor bias. The translation of these results to the clinical setting offers a guide to generate flexible and personalized rehabilitation strategies adaptable to the restrictions of the COVID-19 pandemic.

Expectation and dyspnea: The neurobiological basis of respiratory nocebo effects

Cues such as odours that do not per se evoke bronchoconstriction can become triggers of asthma exacerbations. Despite its clinical significance, the neural basis of this respiratory nocebo effect is unknown. We investigated this effect in a functional magnetic resonance imaging (fMRI) study involving 36 healthy volunteers. The experiment consisted of an Experience phase in which volunteers experienced dyspnea while being exposed to an odorous gas (“Histarinol”). Volunteers were told that “Histarinol” induces dyspnea by bronchoconstriction. This was compared to another odorous gas which did not evoke dyspnea. Actually, dyspnea was induced by a concealed, resistive load inserted into the breathing system. In a second, Expectation phase, Histarinol and the control gas were both followed by an identical, very mild load. Respiration parameters were continuously recorded and after each trial participants rated dyspnea intensity. Dyspnea ratings were significantly higher in Histarinol compared to control conditions, both in the Experience and in the Expectation phase, despite identical physical resistance in the Expectation phase. Insula fMRI signal matched the actual load, i.e. a significant difference between Histarinol and Control in the Experience phase, but no difference in the Expectation phase. The periaqueductal gray showed a significantly higher fMRI signal during the expectation of dyspnea. Finally, Histarinol related deactivations during the Expectation phase in the rostral anterior cingulate cortex mirror similar responses for nocebo effects in pain. These findings highlight the neural basis of expectation effects associated with dyspnea, which has important consequences for our understanding of the perception of respiratory symptoms.

Why are the tarahumara amerindians in mexico such powerful mountain runners?

The Tarahumara Amerindians in Mexico are extremely potent runners on long mountain trails. We have analyzed publications to find causes. Traditionally the Tarahumara live alternating at altitudes between 2400 m and 800 m. Distances from homes to fields and village centers are large and covered on foot since childhood. Men and women take part in running competitions often with kickballs. Investigated runs lasted on average 8:42 h (78 km without ascent) and 6:58 h (63km), respectively. The intensity during the short race amounted to 70% of estimated V˙O2max (ranging between 41 and 70 ml/(kg*min)), energy expenditure reached 21000 kJ. People run barefoot or with thin sandals resulting in increased forefoot impact and storage of elastic energy. This and the slim frame with little subcutaneous fat reduce energy consumption. The vegetarian nutrition contains many carbohydrates and plant proteins, little fat and cholesterol. Hemoglobin concentration tends to increased values. Noncoding beta-chain variants possess no importance for oxygen affinity. The hearts are not enlarged like in endurance athletes. Genes show little European admixture. Gene enrichment in musclerelated pathways suggests a contribution to physical resistance. Conclusions: Explanations for the extreme endurance are favorable biomechanical conditions and physical training beginning during childhood. Running on slopes and changing living sites between 800 and 2400 m play an additional role. Standard exercise tests and genetic investigations are necessary in future.
