Fetus acardius amorphous: a rare case report

Fetus acardius amorphous is a rare fetal malformation, lacking a functional heart and bearing no resemblance to human embryos. The main differential diagnosis is with placental teratoma and is based on the degree of skeletal organization and umbilical cord formation. A 27-year old woman delivered a healthy newborn at 36 weeks gestation. An oval well defined mass, covered with normal looking skin, was connected to the placenta with a thin walled vessel. X-ray examination of the mass revealed the presence of vertebral column. Histopathologic examination demonstrated the presence admixture of tissues including neural tissue, osteoid, cartilage, muscle, fat etc. beneath the skin. The rarity of fetal monsters without a functioning heart is emphasized

The SASSCAL contribution to climate observation, climate data management and data rescue in Southern Africa

A major task of the newly established "Southern African Science Service Centre for Climate Change and Adaptive Land Management" (SASSCAL; www.sasscal.org) and its partners is to provide science-based environmental information and knowledge which includes the provision of consistent and reliable climate data for Southern Africa. Hence, SASSCAL, in close cooperation with the national weather authorities of Angola, Botswana, Germany and Zambia as well as partner institutions in Namibia and South Africa, supports the extension of the regional meteorological observation network and the improvement of the climate archives at national level. With the ongoing rehabilitation of existing weather stations and the new installation of fully automated weather stations (AWS), altogether 105 AWS currently provide a set of climate variables at 15, 30 and 60 min intervals respectively. These records are made available through the SASSCAL WeatherNet, an online platform providing near-real time data as well as various statistics and graphics, all in open access. This effort is complemented by the harmonization and improvement of climate data management concepts at the national weather authorities, capacity building activities and an extension of the data bases with historical climate data which are still available from different sources. These activities are performed through cooperation between regional and German institutions and will provide important information for climate service related activities

Stabilizing the Thermal Temperature of Lithium Batteries Using Peltier Plate for Ev Vehicles

Lithium batteries have become widwly used in energy storage systems. Since adverse operating temperatures can impact battery performance, degradation, and safety achieving a battery thermal management system that can provide a suitable ambient temperature environment for working batteries is important. This paper provides a review based on previous based on previous studies, summarizes the electrical and thermal characteristics of batteries and how they are affected by the operating temperature, analyzes the relative merits and specific purposes of different cooling or heating methods, and provides many optimization mrthods. Moverover, because low power consumption, a high temperature regulation capacity, and excellent temperature uniformity are desired for every battery thermal management system, we also present control strategies that can contribute to thermal management. It is indispensable to establish criteria to evaluate battery thermal management systems. We subsequently summarize the characteristic parameters for the analysis of various battery thermal management system desig s. Finally, we provide an outlook for the development of lithium-ion battery thermal management systems
