Contributing Factors to Under-Five Child Malnutrition in Rural Bangladesh
Background and objectives: Bangladesh has the highest malnutrition rates in the world. The main objective of this study is to identify and determine the main factors for child malnutrition among children under the age 5 years in rural Bangladesh.
Material and methods: This research was conducted in rural areas at Meherpur district in Bangladesh. Convenience sampling method is used and 85 under 5 child information is collected through a structured questionnaire. The information’s of child’s are gathered from the mothers of the child. Malnourished children is measured by using APLS method and WHO Child Growth Standard Median Index. Binary logistic regression model is used to find out the key factors of malnutrition.
Results: It is found that family income, maintain proper diet during pregnancy period, proper diet maintain for children have negative significant (p\u3c0.05) effect on child malnutrition.
Conclusion: The magnitude of the child’s malnutrition still is of great concern in Bangladesh. Since, poverty, imbalanced diet during pregnancy period and imbalanced diet for under 5 children influences to malnutrition are significantly associated with high prevalence of malnutrition, so government and people should reduce these factor to reduce malnutrition in rural area of Bangladesh
Auditor switch decision of Malaysian listed firms: tests of determinants and wealth effect
This article examines the economic rationale for auditor change by Malaysian listed firms by examining audit switch effect on share prices. The auditor change decision by management to retain or to change involves a switch across audit firms with different quality. Audit quality is
defined by classifying the audit firms into Tier 1 (Big-5) firms and Tier 2 (non-Big 5) firms. The distinguishing attribute between the two groups of audit products is believed to be the credibility that each group brings to the audit engagement. Factors associated with the choice of audit firm and changes for firm characteristics associated with auditor choice were investigated using the logistic regression model. The findings show that the auditor switch of Malaysian listed firms is partly explained by changes in management and turnover growth. Changes in firms' characteristics such as asset growth, purchase of fixed asset to total asset, leverage and changes in financing
activities explain auditor switches. There appears to be no evidence of significant wealth effect from auditor switch announcements
Ab-initio insights into the physical properties of XIr3 (X = La, Th) superconductors: A comparative analysis
Here we report the structural, elastic, bonding, thermo-mechanical,
optoelectronic and superconducting state properties of recently discovered XIr3
(X = La, Th) superconductors utilizing the density functional theory (DFT). The
elastic, bonding, thermal and optical properties of these compounds are
investigated for the first time. The calculated lattice and superconducting
state parameters are in reasonable agreement to those found in the literature.
In the ground state, both the compounds are mechanically stable and possess
highly ductile character, high machinability, low Debye temperature, low bond
hardness and significantly high melting point. The thermal conductivities of
the compounds are found to be very low which suggests that they can be used for
thermal insulation purpose. The population analysis and charge density
distribution map confirm the presence of both ionic and covalent bonds in the
compounds with ionic bond playing dominant roles. The calculated band structure
and DOS profiles indicate metallic character. Unlike the significant anisotropy
observed in elastic and thermal properties, all the optical constants of these
compounds exhibit almost isotropic behavior. The optical constants correspond
very well with the electronic band structure and DOS features. We have
estimated the superconducting transition temperature of the compounds in this
work
Comprehensive first-principles insights into the physical properties of intermetallic ZrIr: a noncentrosymmetric superconductor
We have looked into the structural, mechanical, optoelectronic,
superconducting state and thermophysical aspects of intermetallic compound
ZrIr using the density functional theory (DFT). Many of the physical
properties, including direction dependent mechanical properties, Vickers
hardness, optical properties, chemical bonding nature, and charge density
distributions, are being investigated for the first time. According to this
study, ZrIr exhibits ductile features, high machinability, significant
metallic bonding, a low Vickers hardness with low Debye temperature, and a
modest level of elastic anisotropy. The mechanical and dynamical stabilities of
ZrIr have been confirmed. The metallic nature of ZrIr is seen in the
electronic band structures with a high electronic energy density of states at
the Fermi level. The bonding nature has been explored by the charge density
mapping and bond population analysis. The tetragonal ZrIr shows a
remarkable electronic stability, as confirmed by the presence of a pseudogap in
the electronic energy density of states at the Fermi level between the bonding
and antibonding states. Optical parameters show very good agreement with the
electronic properties. The reflectivity spectra reveal that ZrIr is a good
reflector in the infrared and near-visible regions. ZrIr is an excellent
ultra-violet (UV) radiation absorber. High refractive index at visible photon
energies indicates that ZrIr could be used to improve the visual aspects of
electronic displays. All the optical constants exhibit a moderate degree of
anisotropy. ZrIr has a moderate melting point, high damage tolerance, and
very low minimum thermal conductivity. The thermomechanical characteristics of
ZrIr reveal that it is a potential thermal barrier coating material. The
superconducting state parameters of ZrIr are also explored
Giant condyloma acuminatum of vulva
In this paper, A 23 year old married woman who was diagnosed as a case of giant condyloma acuminatum of vulva measuring about 15 x 8 x 3 cm, irregular surface with multiple projections, oval in shape, firm to hard in consistency, mildly tender, exophytic, cauliflower like growth involving the whole vulva (lower part of mons pubis, labia, vestibule, clitoris, around vaginal opening). Another multiple small lesions were present at perineal region but there was no inguinal lymphadenopathy. She underwent a combined electro cauterization and cryotherapy for small to moderate size multiple primary and recurrent warty lesions and wide surgical excision with fasciocutaneous advancement flaps procedure for a giant lesions in the vulva. Excisional biopsies were performed to detect potential malignancy but malignancy was not found histologically. The patient was advised to first follow-up 1 month after operation when multiple small warty lesions were developed and treated and the subsequent follow-ups for 3 months
