Estimation of stature from anthropometry of hand: an interesting autopsy based study in Madhya Pradesh, India
Background: Height of a person is an important parameter for the identification. Height or stature estimation is central dogma in anthropo-forensic examination. The human hand, which is the most used and versatile part of the body is of great scientific importance to investigators in the field of anthropometry, forensic pathology, orthopedic surgery and ergonomics. The hand length was found to be the most reliable alternative that can be used as a basis for estimating age-related loss in height. The hand length could also be used to predict body weight status and body surface area independent of the sex of the individual.Methods: The present cross sectional prospective study was carried out in mortuary of department of Forensic Medicine, Mahatma Gandhi Memorial Medical College and M.Y. Hospital, Indore (M.P.), India during study period from September 2014 to September 2015. The study was conducted on 250 deceased male and 250 deceased female individuals. The measurements were taken using standard anthropometric measuring instruments in centimeters to the nearest millimeters. All the measurements were recorded on a predesigned pretested proforma. Anthropometric measurements were taken as per the standard protocol.Results: The mean age of the male and female study subjects was38.472±13.28 years and 34.728±10.33 years respectively. Male to female ratio was 1:1. Mean stature in male subjects was 163.5±5.21 cm. Mean stature in female subjects was 155.69±10.12 cm. In male study subjects, mean hand length on right side was more than mean hand length on left side. In female study subjects, mean hand length on right side was more than on left side. In male study subjects, hand breadth (HB) on right side was more than on left side. Average HB in male subjects was 8.39±0.203 cm. In female study subjects, hand breadth on right side was more than on left side.Conclusions: The findings of the present study can be used as baseline information for other population based studies in the study area.
Low-frequency dielectric processes in deformed helix ferroelectric liquid crystals
A low-frequency dielectric relaxation mode in deformed helix ferroelectric liquid crystal (DHFLC) has been observed at the interface of strongly rubbed substrates and DHFLC material which may find applications in low power consumption FLC devices. The surface-induced dielectric relaxation process at the interface of DHFLC and substrate is called the partially unwound helical mode (p-UHM) due to the unwinding of the helical structure at this interface. After investigation of the material under various parameters such as temperature, variation of the amplitude of probing ac voltage and dc bias voltage, the relaxation frequency of p-UHM is found to be shifted towards Goldstone mode and merged with it. The relaxation frequency of Goldstone mode is found to decrease, whereas the relaxation frequency of p-UHM process increases with the increase in temperature of DHFLC. Finally, both the modes merge and the resultant relaxation frequency is found to be lower than Goldstone mode in SmC* phase. It seems that phason mode and partial helical unwinding mode are coupled together due to dipole moment that is resulting in a new relaxation frequency. p-UHM process is significant for low-power displays and non-displays applications like a part of sensor where weak electric signal is required to be realized without pre-amplification

ABSTRACT Context Dieulafoy's lesion is an unusual cause of gastrointestinal bleeding with the most common location being the stomach. A periampullary location is rare for a bleeding Dieulafoy's lesion. Case report We present the case of a 52-year-old female who presented with intermittent painless melena. Her upper gastrointestinal endoscopy and colonoscopy were normal. She was a diagnostic challenge as no definite lesion could be identified on capsule endoscopy. However, as there was presence of fresh blood in the proximal jejunum, a push enteroscopy was performed which revealed the presence of fresh blood in the duodenum and proximal jejunum. But no bleeding lesion could be identified. A side view endoscopy was performed which revealed a bleeding periampullary Dieulafoy's lesion. Immediate hemostasis was achieved with an injection of adrenalin. Other episodes of bleeding occurred and the patient was finally treated surgically. Conclusion A periampullary Dieulafoy's lesion presenting with obscure gastrointestinal bleed is a diagnostic challenge and can be missed on capsule endoscopy
Selective detection of fluoride and hydrogen sulfate anions by pyrimidine-based fluorescence chemosensor
1809-1813The binding and sensing abilities of pyrimidine based fluorescence chemosensor L towards different anions such as F-, Cl-, Br-, I-, NO3-, ClO4-, H2PO4- and HSO4- have been examined by fluorescence spectroscopy in DMSO-H2O (7: 3, v/v). Upon successive addition of various anions to DMSO-H2O solutions of L; quenching in emission fluorescence is observed at 480 nm. Analysis of fluorescence emission changes suggested the formation of 1:1 complex of L with the anions. From the fluorescence binding constant data, it is found that L form strong complexes with F- and HSO4- ions through H-bonding interactions. The selective response of F- over other halides and HSO4- amongst other oxo-anions towards L may be explained on the basis of photo-induced electron transfer process
Decay studies of alpha-decay chains
The -decay chains of are studied along with the
possible cluster decay modes by using the preformed cluster model (PCM). The
calculated -decay half-lives are compared with experimental data and
other model calculations. The calculated Q-values, penetration probabilities
and preformation probabilities factors for -decay suggest that
, and parent nuclei are
more stable against the -decay. These alpha decay chains are further
explored for the possibilities of cluster decay. Decay half lives of different
cluster from different nuclei of the decay chains point to the extra stability
near or at the deformed shells Z=108, N=162 and Z=100, N=152. The decay
half-lives for and clusters are lower than the current
experimental limit ( sec)
Dynamics of Hot QCD Matter -- Current Status and Developments
The discovery and characterization of hot and dense QCD matter, known as
Quark Gluon Plasma (QGP), remains the most international collaborative effort
and synergy between theorists and experimentalists in modern nuclear physics to
date. The experimentalists around the world not only collect an unprecedented
amount of data in heavy-ion collisions, at Relativistic Heavy Ion Collider
(RHIC), at Brookhaven National Laboratory (BNL) in New York, USA, and the Large
Hadron Collider (LHC), at CERN in Geneva, Switzerland but also analyze these
data to unravel the mystery of this new phase of matter that filled a few
microseconds old universe, just after the Big Bang. In the meantime,
advancements in theoretical works and computing capability extend our wisdom
about the hot-dense QCD matter and its dynamics through mathematical equations.
The exchange of ideas between experimentalists and theoreticians is crucial for
the progress of our knowledge. The motivation of this first conference named
"HOT QCD Matter 2022" is to bring the community together to have a discourse on
this topic. In this article, there are 36 sections discussing various topics in
the field of relativistic heavy-ion collisions and related phenomena that cover
a snapshot of the current experimental observations and theoretical progress.
This article begins with the theoretical overview of relativistic
spin-hydrodynamics in the presence of the external magnetic field, followed by
the Lattice QCD results on heavy quarks in QGP, and finally, it ends with an
overview of experiment results.Comment: Compilation of the contributions (148 pages) as presented in the `Hot
QCD Matter 2022 conference', held from May 12 to 14, 2022, jointly organized
