Asteroid models from the Lowell Photometric Database
We use the lightcurve inversion method to derive new shape models and spin
states of asteroids from the sparse-in-time photometry compiled in the Lowell
Photometric Database. To speed up the time-consuming process of scanning the
period parameter space through the use of convex shape models, we use the
distributed computing project Asteroids@home, running on the Berkeley Open
Infrastructure for Network Computing (BOINC) platform. This way, the
period-search interval is divided into hundreds of smaller intervals. These
intervals are scanned separately by different volunteers and then joined
together. We also use an alternative, faster, approach when searching the
best-fit period by using a model of triaxial ellipsoid. By this, we can
independently confirm periods found with convex models and also find rotation
periods for some of those asteroids for which the convex-model approach gives
too many solutions. From the analysis of Lowell photometric data of the first
100,000 numbered asteroids, we derived 328 new models. This almost doubles the
number of available models. We tested the reliability of our results by
comparing models that were derived from purely Lowell data with those based on
dense lightcurves, and we found that the rate of false-positive solutions is
very low. We also present updated plots of the distribution of spin obliquities
and pole ecliptic longitudes that confirm previous findings about a non-uniform
distribution of spin axes. However, the models reconstructed from noisy sparse
data are heavily biased towards more elongated bodies with high lightcurve
amplitudes

Combustion Gas Properties I-ASTM Jet a Fuel and Dry Air
A series of computations was made to produce the equilibrium temperature and gas composition for ASTM jet A fuel and dry air. The computed tables and figures provide combustion gas property data for pressures from 0.5 to 50 atmospheres and equivalence ratios from 0 to 2.0

"Worship at Times of Killings and Confusion Equals Migration to Me" /
This research is concerned with the study of Prophet Mohammad's Hadith "Worship at times of killings and confusion equals migration to me" from the perspective of narrative and text criteria. It attempts to elaborate the Hadith's benefits and related academic issues. It also shows the Islamic approach to dealing with afflictions / confusing trials. It aims to rank the Hadith in terms of authenticity and weakness, to show the similarity between worship at trial times and migration to the Prophet, and to highlight the Islamic approach to trials.
The research applies an analytical deductive methodology. It has arrived at the following conclusions: Prophet Mohammad cared for his nation, guided it, conveyed to it what guarantees success in this world and the hereafter; the Qur'an and the Sunnah contain the approach that must be followed at times of trials and killing; at such times, acts of worship and righteous deeds are important; and it is important to test information, especially that circulating in the social media. The research makes recommendations, amongst which are the following: organize conferences and forums on causes and solutions for affliction trials; conducting related research projects by universities and research centers to elaborate the Islamic approach at trial times; and make use of the mainstream and social media to reinforce the values of social cohesion, preventing confusion and dissension
Enfermedad arterial periférica y control glucémico inadecuado en pacientes diabéticos
La Diabetes Mellitus es una entidad de etiología multifactorial, se distingue por
presentar afectación del tipo celular beta del páncreas, cuando cursan con valores
de hemoglobina glicosilada < 7% en fase inicial de la patología está asociado a
reducción de complicaciones microvasculares; por ello este estudio de
investigación esquematizó como objetivo general identificar la relación entre la
enfermedad arterial periférica y control glucémico inadecuado en pacientes
diabéticos, cuya metodología empleada incluía un tipo de investigación básica, no
experimental, relacional; en donde se realizó un análisis documental a mediante la
recolección de información de 168 historias clínicas, cuya población estuvo
comprendida por los pacientes con diabetes mellitus, mayores de 18 años
integrados en un Hospital de Chimbote, siendo los criterios de inclusión aquellos
individuos con diagnóstico de diabetes Mellitus y edad superior a 18 años atendidos
durante los años 2022 y 2023; por ultimo en el método de análisis de datos se
ejecutó la prueba no paramétrica de independencia de criterios empleando Chicuadrado
con un P<0.05 y el odds ratio. Conclusiones: Según lo evidenciado con
respecto a la relación entre enfermedad arterial periférica y control glucémico
inadecuado se puede inferir que no guarda relación significativa
