Compact stars in gravity
In the present paper we generate a set of solutions describing the interior
of a compact star under theory of gravity which admits conformal
motion. We consider the equation of state (EOS) with
for the fluid distribution consisting normal matter,
being the EOS parameter. We therefore explore several aspects of the model
analytically along with graphical representations to check the physical
validity as well as acceptability of it within specified observational
constraint in connection to a dozen of the compact star candidates. It is shown
from the presented model that these objects are nothing but radiating compact
stars.Comment: 16 pages, 6 figures, 1 table, substantial modification based on

Clinicopathological profile of malaria patients in an Central African United Nations hospital
Background: Malaria is one of the most widespread diseases in the world. It is endemic in 91 countries. Each year 300-500 million cases of malaria are confirmed with 1.5-2.7 million deaths. Malaria is a major public health problem in Africa. A large number of united nations troops are deployed in central Africa making them vulnerable to malaria infection. Present study was undertaken to find out the clinical and laboratory findings of malaria cases in a United Nation’s referral hospital in Central Africa.Methods: It is a retrospective study of 150 confirmed and treated cases of malaria for a period of one year in a referral hospital for peace keeping troops and employees of United Nations in Democratic Republic of Congo (DRC). Patients positive by ICT or slide positive were included. Detailed history, examination and lab features of these patients were recorded and analyzed.Results: A total of 150 patients were included in the study. Out of which 145 patients were of pure P. falciparum malaria, 02 patients had only P. vivax, and 03 patients were having mixed malaria. Fever was the main symptoms found in all patients. Headache was the second most predominant symptoms in (70%) patients. Other signs and symptoms were vomiting (31%), myalgia (38%), jaundice (10%), hepatosplenomegaly (15%), pallor (42%) and decreased urine output (8%). Duration of symptoms was between 4 to 15 days. Thrombocytopenia was observed in 43% patients. Jaundice in (10%), transaminitis in (25%). Anaemia was seen in 53% patients.Conclusions: Malaria was found to be the most common cause of admission in our hospital. It is important to suspect malaria in all persons deployed in DRC and presenting with fever and associated headache, jaundice, transaminitis and thrombocytopenia. Early diagnosis and treatment can be lifesaving to prevent complications and mortality
Erythrophagocytosis and its relation to band 3 clustering in chronic myelogenous leukemia
Band 3, a major erythrocyte membrane glycoprotein, undergoes topographic redistribution leading to enhanced clustering, in chronic myelogenous leukemia (CML). This is probably due to the binding of heme compounds to the CML erythrocyte membrane resulting from depletion of cellular levels of reduced glutathione (GSH). Band 3 clustering appears to be one of the factors associated with increased erythrophagocytosis in CML
Design and Fabrication of Industrially Scalable low cost Liquid Impregnated Surfaces with extreme hydratephobic properties
The design and fabrication of extremely hydrate phobic Liquid Impregnated
Surfaces (sometimes abbreviated as LIS) based on industrial material Aluminium
Al6061 and industrially scalable low-cost method were carried out. A simple
hydrochloric acid-based etching method and boiling water treatment were used to
generate micro and nanoscale nanopetal roughness features respectably. A
theoretical analysis was performed to find out the relationship between the
interfacial interactions and surface roughness features to predict the
stability of lubricant oil of LIS under water and oil environment. LIS with
appropriate surface chemistry and textures were fabricated to experimentally
validate the theoretical analysis on lubricant stability. Subsequent
experimental measurements of hydrate adhesion were performed on LIS with stable
lubricant layers, using a custom-made experimental setup and cantilever-based
method. Cyclopentane hydrate, mimics gas hydrate forming mechanism at
atmospheric pressure, and is used for the hydrate adhesion measurements.
Extreme reduction of hydrate adhesion with more than four orders of magnitude
was observed on LIS compared to control smooth aluminium surface
