Walking while Talking in Older Adults with Chronic Kidney Disease
Authors: Ho Jim Q. , Verghese Joe , Abramowitz Matthew K. 
Published: March 2020

Background and objectives
Walking while talking is a dual cognitive-motor task that predicts frailty, falls, and cognitive decline in the general elderly population. Adults with CKD have gait abnormalities during usual walking. It is unknown whether they have greater gait abnormalities and cognitive-motor interference during walking while talking.

Design, setting, participants, & measurements
Community-dwelling, nondisabled adults (n=330) ≥65 years of age underwent quantitative gait analysis, including walking while talking. Differences in walking-while-talking performance by CKD status were evaluated, and relative changes between walking-while-talking and walking alone performance were computed to quantify cognitive-motor interference (dual-task cost). Associations were tested using multivariable linear spline regression models, and independent gait domains were derived using factor analysis. CKD was defined as an eGFR<60 ml/min per 1.73 m2.

Results
CKD was present in 134 (41%) participants. Participants with CKD had slower gait speed along with various gait cycle abnormalities during walking while talking: among those with CKD, every 10-ml/min per 1.73 m2 lower eGFR was associated with 3.3-cm/s (95% confidence interval, 0.4 to 6.1) slower gait speed, 1.8-cm (95% confidence interval, 0.6 to 3.0) shorter step length, 1.1% (95% confidence interval, 0.6 to 1.7) less time in the swing phase, and 1.4% (95% confidence interval, 0.5 to 2.3) greater time in double support after multivariable adjustment. When comparing walking while talking with walking alone, every 10-ml/min per 1.73 m2 lower eGFR was associated with 1.8% (95% confidence interval, 0.5 to 3.2) greater decrease in time in the swing phase and 0.9% (95% confidence interval, 0.2 to 1.5) greater increase in time in the stance phase. Factor analysis identified three walking-while-talking domains and three dual-task cost domains: eGFR was associated specifically with the rhythm domain for both walking-while-talking and dual-task cost. Every 10-ml/min per 1.73 m2 lower eGFR was associated with a poorer performance of 0.2 SD (95% confidence interval, 0.1 to 0.3) for walking while talking and 0.2 SD (95% confidence interval, 0.03 to 0.3) for dual-task cost.

Conclusions
During walking while talking, CKD is associated with gait abnormalities, possibly due to increased cognitive-motor interference.
¿Pueden los derechos naturales hacer alguna contribución a la filosofía de los derechos humanos?
Authors: Montero Julio 
Published: March 2020

Durante décadas, los filósofos han concebido los derechos humanos como una clase de derechos naturales de los que gozamos por el mero hecho de ser seres humanos. Sin embargo, esta interpretación ha sido severamente cuestionada en los últimos años. Toda una familia de autores, identificados con una concepción “práctico-dependiente”, asevera que los derechos humanos constituyen una práctica sui generis completamente ajena a la tradición del derecho natural. En contra de esta postura, este artículo argumenta que el discurso de los derechos naturales es parte constitutiva de la doctrina actual de los derechos humanos y que puede hacer un aporte crucial a la adecuada justificación y comprensión de sus funciones, su contenido y su alcance normativo. Más concretamente, mi tesis será que si bien los derechos humanos no pueden reducirse a derechos naturales, bien podrían derivar de derechos naturales previos.

SOIL LAYER CUT OFF BY THE AGGREGATE FOR REMOVING THE TOPSOIL FROM THE ROAD SUBLAYER: DETERMINATION OF THE CHAIN SPEED AND SIZES
Authors: Nikolaev V. A. 
Published: March 2020

Introduction.For the durable road at the minimum necessary cost of its construction the topsoil should be removed without affecting the ground. The problem of cheaper road construction without reducing the quality can be solved by creating an aggregate for the sublayer’s formation. The aggregate removes the topsoil from half of the road sublayer and one of the ditch. The buckets of the moving aggregate cut off the soil layer from below and from one side. Therefore, each bucket is mounted by the bottom blade, the right blade and the console blade, partially cutting the topsoil from below for the passage of the next bucket. The blade of the lower knife with the 10 degrees’ angle to the plank of the bucket; the blade of the right knife and the blade of the console knife – with the 45 degrees’ angle towards the direction of the bucket moving.Materials and methods. To determine the speed of chains and the size of the soil layer the author carried out the bucket kinematics’ analysis and considered mathematical transformations. For checking the received parameters, the paper demonstrated the turn of the bucket on the leading 90 degrees’ lower drive. The author revealed the scheme of forces acting on the ground, located in the bucket, when it turned on the leading lower drive. Based on the system’s transformations of two equations and the inequality, the research established the inadmissibility of the bucket’s phasing out when it turned on the leading lower drive.Results. As a result, by using the developed method of determining parameters, based on the accepted raw data, the author calculated the speed of the chains, to which the buckets were attached, and the width of the soil, cut off by the bucket. After substitution of the received parameters in the inequality the author established that the ground would not fall out of the bucket by turning under such parameters of the bucket and of the leading lower drive.Discussion and conclusions.As a result, the author obtains the geometric parameters from the structural layout of the aggregate for removing the topsoil from the road sublayer. Based on the analysis of the kinematics of the interaction of the bucket with the ground, the paper reveals the speed of the chains, to which the buckets are attached and the width of the soil layer cut off by the bucket. Analysis of the forces acting on the ground and locating in the bucket at the moment of the bucket turn on the leading lower drive shows the rationality of the accepted and calculated parameters. The author determines the energy costs of cutting the ground with the buckets of the aggregate for removing the topsoil from the road sublayer.Financial transparency: the author has no financial interest in the presented materials or methods.

STRESSED-DEFORMED STATUS OF THE HANGING HYDROCYLINDER: INFLUENCE OF THE CONJUGATED ELEMENTS’ PAIRS
Authors: Potakhov D. A. 
Published: March 2020

Introduction. The contact interaction of the associated elements of the hydraulic cylinder (piston with sleeve, guide sleeve with cylinder and rod) determines the reliability of the reciprocating hydraulic motor. Assessing the effect of gaps of articulated hydraulic cylinder elements is an urgent task in view of the fact that the formation of gaps is inevitable, since friction is always accompanied by tribological wear processes. The paper investigates the determination and assessment of the influence of the gaps of the hydraulic cylinders’ mating elements on the stress-strain state of the contacting bodies on the example of the hydraulic cylinder for the Sokol 80.01 railway crane.Materials and methods. The author used the finite element method implemented in the Simulation SolidWorks module. Moreover, the author applied the Huber–Mises criterion as a criterion for the material plasticity. The paper also considered theoretically possible spatial design schemes of loading and depending on the type of the mating elements’ contacting of the hydraulic cylinder.Results. As a result, the author presented plots and graphical dependences, which were three-dimensional surfaces constructed according to the results of numerical experiments. The calculations took into account the joint deformation of the piston, sleeve, rod, guide sleeve and supporting guide rings of the hydraulic cylinder. The author carried out the analysis of the obtained diagrams and dependences of the contact interaction of the hydraulic cylinder for various options of the elements contacting. The paper presented the results that were useful for studying all types of hydraulic cylinders and working equipment of the road, construction and hoisting-andtransport machines.Financial transparency: the author has no financial interest in the presented materials or methods.

Maggot black soldier fly (Hermetia illucens) is a protein source of feed which is highly favored by poultry, especially ducks and chickens. However, it is feared that the provision of live maggot in ducks will affect the organoleptic quality of the egg, especially its taste and aroma. Therefore this study aims to determine the organoleptic quality of duck eggs fed Hermetia illucens maggot feeds in a living state. The study used 120 alabio ducks which were placed in a postal cage. The design used was a completely randomized design, each treatment using six replications. Each replication is taken egg sample to be tested panelists. The panelists used were 67 panelists who were somewhat trained. The data obtained were analyzed of variance and Duncan's multiple range test. The treatments that were tried consisted of P1: low protein rations without live maggot, P2: low protein rations with live maggot administration 40 g/bird/day, P3: high protein rations without live maggot administration, and P4: high protein rations with live maggot administration 40g/bird/day. The results showed that the treatment affected the texture, flavor, and aroma of boiled eggs. Ducks fed with high protein ration coupled with the provision of live maggot 40 g/bird/day produce softer textures, tastes quite good, and aroma more fishy. Keywords: Maggot, duck eggs, organoleptics

Collapse
Authors: Smith Constance 
Published: March 2020

AbstractIn Nairobi, the speed of urban growth is producing a parallel threat of architectural failure: in a recent spate of tower block collapses, many have died. Nairobians describe collapsed tower blocks as “fake,” referring to ideas of the counterfeit, as well as anxieties about morally suspect economies. Simultaneously, state-led development is re-envisioning Nairobi as a “world-class” city of spectacular infrastructure and gleaming high-rises. Though seemingly disconnected processes, the two are deeply entangled. Building on Africanist debates about the power of the double and the relationship between the surface and the underneath, I explore this superficially sleek but materially fragile landscape through a lens of “gray development,” complicating standard distinctions between the informal and the formal to uncover the underneath of Nairobi's world-class fantasies.
“Going vertical” in times of insecurity
Authors: Goodman Zoë 
Published: March 2020

AbstractThe global proliferation of elite high-rise apartments is often read as evidence of social failure, of increasing socioeconomic disparity and fragmentation. The Jaffery Complex, a vertiginous gated high-rise being constructed in the Kenyan port of Mombasa, seems to embody Corbusian ideologies of social transformation based on an explicit distancing from the streets below, insulating its incoming residents from the frequently fused threats of terror, poverty, and crime. However, ethnographic attention to the multistory mosque located within the complex challenges readings of elite stacked housing solutions as “vertical cocoons,” and reveals the tension between proximity and distance that this urban redevelopment strives to construct.
