A case report of a 38 years old ABO group A and Rhesus D negative multiparous, gravidae 8 and para 2, Nigerian woman who had a case of premarital miscarriage and who was not offered anti-D prophylaxis as part of her management. Lady went on to develop alloantibody D and Jka. Lady has had 7 further pregnancies post the miscarriage. The first child who is B Rhesus D positive is the only surviving child. The surviving child was delivered severely jaundiced and needed management post-delivery for haemolytic disease of the foetus and newborn (HDFN). Lady has had a history of a stillbirth. She was given a non-clinically indicated anti-D prophylaxis during the second pregnancy despite having been previously sensitized. The second baby died 3 months after delivery from complications of HDFN. She had had a further history of 5 miscarriages. She has had challenge with conception since 2010. Alloantibody testing confirms the presence alloantibody D and anti-Jka. Finding from this is a clear case of sub-optimal laboratory, obstetric and neonatal care offered particularly to pregnant women who are Rh D negative and those with alloantibodies in Nigeria. The Nigerian government will need to implement evidenced-based best practices; determination of alloantibody status of pregnant women during their first antenatal visit; provision of facilities for alloantibody identification, titration, quantification and feto maternal haemorrhage testing (FMH); implementation of a policy on universal access to anti-D prophylaxis for pregnant Rh D negative women who are not previously sensitized; provision of facilities required for the optimal intrauterine management of HDFN (foetal genotype testing, intrauterine transfusion, doppler ultrasound to diagnose anaemia inutero and provision of donor blood that meet the minimum requirements for intrauterine transfusion); determination of Rh D status of women who require a termination of pregnancy and provision of prophylactic anti-D for those found Rh D negative within 72 hours of procedure and the optimization of the knowledge of Medical Laboratory Scientist, Obstetricians, Neonatologist, Pharmacist and Traditional Birth Attendants in a bid to reduce the residual number of women who become sensitized and the number of preventable deaths of babies with HDFN.

Background: Black Americans are approximately twice as likely to develop dementia as compared to White Americans and the magnitude of this disparity is often attributed to a variety of factors that include psychosocial and vascular risk factors. However, less is known about the potential contribution of Alzheimer’s disease pathological differences. Objective: To examine potential differences incross-sectional and longitudinal cognitive performance in black and white participants who were clinically normal at baseline. Methods: 296 participants (48 African-American/black participants) underwent MRI and amyloid PET at baseline. Linear mixed models were used to examine the main effects of race, years of education, reading ability, Framingham Heart Study cardiovascular risk score (FHS-CVD), white matter hyperintensities (WMH), and amyloid (Aβ) burden on the Preclinical Alzheimer Cognitive Composite-5 (PACC5). Results: Lower levels of educationalattainment and reading ability were found for blacks compared to whites. By contrast, no differences in FHS-CVD, WMH, or Aβ were found by racial group. Baseline differences in PACC5 score were attenuated after adjusting for educationalfactors, vascular factors, and Aβ, but remained lower for blacks compared to whites (β= –0.24, p = 0.014). Further, blacks demonstrated a faster rate of PACC5 decline longitudinally compared to whites (β  = –0.055, p = 0.025) after adjusting for covariates. Conclusion: Accounting for educationalfactors, vascular factors, and Aβ burden diminished, but did not eliminate, racial differences in PACC5 performance longitudinally. Understanding potential differences in longitudinal cognitive outcomes by race may be important for upcoming secondary prevention trials.

The pressure of the products of chemical reactions in the chamber of a rocket engine increases significantly if the rocket fuel components burn in the detonation mode. In this case, it can get to a simpler and more reliable expulsion propellant feed system instead of a turbopump feed system. The value of heat release power (MW / liter) of detonation engines is several orders of magnitude larger than that of aircraft and rocket engines operating in the Brighton cycle. The high rate of energy released in the detonation mode can significantly reduce the mass, the inertia, and overall dimensions of the propulsion system. Due to these features, detonation chambers are advisable to be used as part of ejector pulsed detonation engines, together with a turbine – in electric power generators of spacecraft, in a hybrid design – together with turbofan or turboprop engines, etc. In the article are considered various design schemes of pulse detonation engines (PDE): single-chamber and multi-chamber pulsed detonation engines; an ejector PDE system; a hybrid PDE and an integrated detonation-turbine unit with a detonation chamber in the form of a spiral and with a multi-chamber detonation device. The possibility of pulsation frequency increase is realized in the multi-chamber pulsed detonation engine, and the possibility of thrust size increase is realized in PDE with ejector. Replacing traditional chambers with detonation chambers in the construction of gas turbine jet engine will allow providing a decrease in propellant flow rate value from 8 % to 10 % on some estimations. In the hybrid detonation propulsion plant advantages inherent to the detonation cycle combine with positive features of a turbo-compressor jet engine. A combination of PDE and turbine allows creating the cogeneration propulsion system in that a turbine is used for the production of electric power, and detonation chamber – for the creation of thrust impulse. Practical realization of hybrid pulse detonation turbo-engine and the integrated detonation-turbine device is possible if two key complex problems will be solved. These problems are the detonation waves weakening on input in a turbine and the bearing and shaft necessary work resource increasing into a detonation pulsating stream

When studying the influence of the fractional composition of the working mixture of powders on the characteristics of solid mixed rocket fuel (SMRF), optimization is proposed using the jumping frog method to construct time-optimal experimental designs. It is known that the proportion of the fractional agent (FA) product in the composition of SMRF is the largest and amounts to 80 %. Consequently, the FA product has one of the greatest effects on the whole range of physicochemical properties of SMRF. Thus, the task of determining the effect of the FA product on the properties of SMRF is very relevant. The application of experimental design methods reduces the cost and time costs in the study of various technological processes, devices, and systems. Minimizing the number of transitions of factor levels in terms of the experiment, in turn, leads to a decrease in the cost (time) of its implementation. The goal of the work is the optimization of the full factorial experiment time-lapse experiment using the jumping frog method. To this end, a method is proposed for constructing a time-optimal implementation of the experiment planning matrix using the jumping frog algorithm. In the jumping frog method, a successful frog is determined by the least transition time between levels for each of the factors. After that, frog permutations are performed. The frog strives for the most successful and, if located nearby, remains in its current location. The software has been developed that implements the proposed method, which was used to conduct computational experiments to study the properties of this method when studying the influence of the fractional composition of the working mixture of powders on the characteristics of solid mixed rocket fuel. The experimental plans optimal in terms of implementation time were obtained, and also the winnings in the optimization results are given in comparison with the initial experiment time. A full factorial experiment was carried out to study the effect of the fractional composition of the working mixture of powders on the characteristics of SMRF, based on which recommendations were made regarding the effect of the fractional composition of the working mixture of powders and the content of liquid-viscous components in the composition on the properties of SMRF. Mathematical models are also constructed, the coefficients of which characterize the effect of the content of liquid-viscous components in the composition on the properties of the SMRF. The experiments confirmed the efficiency of the proposed method and the software that implements it, and also allow us to recommend it for practical use in constructing the optimal planning matrices of the experiment.
