Sudden infant death syndrome: a subject of medicolegal research

During the last decade, much attention has been paid to the risk factors of sudden infant death syndrome (SIDS). Many researchers have demonstrated that infant-care practices are linked to the risk of SIDS. Prone sleeping, bed sharing, maternal substance abuse, and cigarette smoking have been reported to be significant potentially modifiable risk factors for SIDS. Despite the reports that the incidence of SIDS has decreased by 38% in the United States, it remains the leading cause of death in the first year of life. Deaths resulting from child abuse or neglect inflicted or permitted by their caretakers being second only to SIDS in infant mortalities and some recommendations regarding the differentiation of SIDS and child abuse have generated speculation that some cases of infanticide were misdiagnosed as SIDS. To reach a proper conclusion as to the cause and manner of death of an infant who died suddenly and unexpectedly, investigation must be thorough and professional.     

Variation of δ2H, δ18O & δ13C in crude palm oil from different regions in Malaysia: Potential of stable isotope signatures as a key traceability parameter

A total of 33 crude palm oil samples were randomly collected from different regions in Malaysia. Stable carbon isotopic composition (δ¹³C) was determined using Flash 2000 elemental analyzer while hydrogen and oxygen isotopic compositions (δ²H and δ¹⁸O) were analyzed by Thermo Finnigan TC/EA, wherein both instruments were coupled to an isotope ratio mass spectrometer. The bulk δ²H, δ¹⁸O and δ¹³C of the samples were analyzed by Hierarchical Cluster Analysis (HCA), Principal Component Analysis (PCA) and Orthogonal Partial Least Square-Discriminant Analysis (OPLS-DA). Unsupervised HCA and PCA methods have demonstrated that crude palm oil samples were grouped into clusters according to respective state. A predictive model was constructed by supervised OPLS-DA with good predictive power of 52.60%. Robustness of the predictive model was validated with overall accuracy of 71.43%. Blind test samples were correctly assigned to their respective cluster except for samples from southern region. δ¹⁸O was proposed as the promising discriminatory marker for discerning crude palm oil samples obtained from different regions. Stable isotopes profile was proven to be useful for origin traceability of crude palm oil samples at a narrower geographical area, i.e. based on regions in Malaysia. Predictive power and accuracy of the predictive model was expected to improve with the increase in sample size. Conclusively, the results in this study has fulfilled the main objective of this work where the simple approach of combining stable isotope analysis with chemometrics can be used to discriminate crude palm oil samples obtained from different regions in Malaysia. Overall, this study shows the feasibility of this approach to be used as a traceability assessment of crude palm oils.     

The role of institutional and governance factors in public–private partnerships infrastructure investments in emerging economies

The overall development and sustained growth of any economy depend heavily on its infrastructure provisioning. Emerging economies are usually characterised by constrained public investments in infrastructure. Budgetary constraints of the governments are one of the major hurdles to these investments. Due to these reasons that governments of emerging economies continuously seek collaborations with the private sector for additional sources of funding infrastructure. Economies with solid institutional and governance frameworks are known to provide a conducive environment for enhanced private sector attraction in the sector. However, emerging economies face greater institutional and governance issues than developed economies, and they sometimes fall short of luring private investments in the infrastructure sector. The objective of this study is to empirically evaluate the role of institutional and governance aspects in private sector attraction in emerging economies. This study provides empirical evidence with a sample of 114 emerging economies over a period of 20 years. Various econometric estimates were developed to explore the interplay between public-private partnership investments and governance factors. The results of the study provide an evidence of a positive association between these factors and private investments in public-private partnership arrangements.     

Exposure of Air Pollution and Its Health Effects in Traffic Police Persons of Gwalior City,India

This article examines the perceived health effects of air pollution among traffic police persons of Gwalior city, India. The first part of the results reveals the health effects of air pollution on respondents and the second part reports the awareness of respondents regarding air pollution, pollutants, particulate pollutants, gaseous pollutants, and sources of pollutants etc. This perceptional study examines twenty-two types of health effects and an option for other health effects was also included. Eye irritation and sleeplessness were found consistently while difficulty in concentration, headache, sneezing, and nose irritation were found in less extant. A part of health effects were very serious and not curable. Traffic police persons were neither aware adequately regarding air pollutants nor used any type of personal protective equipment. The study covers respondents of four age categories: 15–24, 25–34, 35–44, and 45-above.     

Educational Space Settlement: Mantavya

The goal of the Educational Space Settlement proposed herein, which is called Mantavya (Hindi for “to prepare the preliminary sketch”), is to act as an all-encompassing education and training hub in space. The structure is designed with an awareness of the physiological, psychological, and aesthetic needs of future colonists in space to offer an almost Earth-like environment. There are six segments of the settlement serving educational, residential, and agricultural needs, which are built up around a central axis. These segments will be used to provide education in various research and development areas, which include study of agriculture, communication, life support systems, robotics, medical sciences, material sciences, and astronomy. The variable gravity at different locations will provide new horizons of research for the inhabitants. An unpressurized region below the segmented parts of the hub will provide a microgravity training zone for space walks and disaster management.
