Up to now several researchers use values of basic inertial quantities of human body parts obtained for old cadavers. Taking into account the trunk researchers presented this body part often as one ...segment only and rarely as few-segment part. The purpose of this study was obtaining values of basic inertial quantities of body parts including five parts of the trunk for young, fit living males. Thirty young, fit males (age: 24 ± 4 years, height: 179 ± 6 cm, body mass: 74 ± 7 kg) were directly measured (circumferences and skin-fat folds) and photographed in order to use these data for Clauser et al. (parts of extremities) and Erdmann’s (parts of trunk) methods for estimation of mass and location of centres of mass of body parts. These methods take into account personal data for estimating inertial quantities. Relative mass (according to the mass of the whole body) of trunk parts (sum of thorax + abdomen + pelvis but without shoulder girdle) of subjects investigated in this work was similar to that obtained by Dempster for old cadavers. Relative mass differed for shoulders and for lower extremities. Old subjects for both lower extremities had around 31–32% of the whole body mass and young subjects had almost 37%. Procedure for obtaining location of the whole body centre of mass for graphical method (summation of mas) was presented. Obtained data are very important for analyses of arched trunk, e.g. in high jumping, pole vault jumping, rhythmic gymnastics of young, fit athletes and also for models of young passengers in car-crash tests, for ergonomics and medical analyses and other purposes.
In this paper we provide integrative description (morphological and genetic) of the new eutardigrade species Mesobiotus mandalorisp. nov. from central Poland, found during research on the vertical ...distribution of Tardigrada in the Czerniejewskie Forests. Mesobiotus mandalorisp. nov. belongs to the harmsworthi group, but it differs from the members of this group in some morphometric characters of the bucco-pharyngeal apparatus, claws and/or eggs. Morphologically, Meb. mandalorisp. nov. is most similar to Meb. pseudocoronatus, but it differs from it by a larger bare egg diameter and smaller number of egg processes on egg circumference. Morphometrical data were supported by results of comparative genetic analysis of four molecular markers: 18S rRNA, 28S rRNA, ITS2 and COI. According to COI the new species is most similar to Meb. skorackii with the genetic distance of 21.1%.https://zoobank.org/urn:lsid:zoobank.org:act:0222E328-CF9E-4D04-8F8C-69C80515FEE2

The readout chip for the CMS pixel detector has to deal with an enormous data rate. On-chip zero suppression is inevitable and hit data must be buffered locally during the latency of the first level ...trigger. Dead-time must be kept at a minimum. It is dominated by contributions coming from the readout. To keep it low an analog readout scheme has been adopted where pixel addresses are analog coded.
We present the architecture of the final CMS pixel detector readout chip with special emphasis on the analog readout chain. Measurements of its performance are discussed.

The H1 experiment at the ep collider HERA has been equipped with a silicon strip detector, mainly for the purpose of heavy flavor physics. First results have recently become final. The vertexing ...techniques and strategies employed in H1 are reviewed.
Abstract
Background
Tranexamic acid (TXA) can reduce intra- and postoperative bleeding as well as minimizing postoperative swelling and ecchymosis. It can be administered both intravenously and ...topically during surgery with minimal side effects.
Objectives
To assess the evidence of TXA use in aesthetic surgery and to complete a survey of current practice of full British Association of Aesthetic Plastic Surgeons members.
Methods
The authors performed a literature review and online survey of full British Association of Aesthetic Plastic Surgeons members.
Results
There is an increased indication of TXA utilization in aesthetic surgery. It provides multiple surgeon and patient benefits.
Conclusions
TXA is a useful adjunct in aesthetic surgery.
