One of the best indicators for public health outcome and service is the immunization rates of the country. Knowledge of parents regarding immunization is one of the key factor affecting immunization rates in the society. This study was aimed at assessing the knowledge attitude and practice of parents regarding immunization and its correlation with the immunization status of the child. A cross-sectional study was done in the immunization room of a tertiary care hospital in Rohtak city to evaluate immunization KP of parents from 12 Jan 2015 to 20 Jan 2015 who came for immunization of their child. A total of 104 parents were interviewed by using a predesigned questionnaire. Out of 104 parents interviewed 73 have got their child fully immunized 63% children were from urban areas. Children with highly educated mothers were more likely to miss their immunization schedule. Local health care workers were the prime source of information regarding immunization services. Child's health status was most important factor in missing immunization doses at specified time. Negative attitude of parents was the most important factor affecting the immunization status of the child. Mother's age, education, working status, socioeconomic status do not significantly affected the immunization pattern. Aggressive information dissemination and involvement of family are crucial for achieving higher immunization rates in the society.Keywords

Pearl millet (Pennisetum glacum (L) RBr) provides 11-12% of the world's supply of proteins, 67.5% of carbohydrate and 8.8% of iron. Though the maximum acreage and production of pearl millet is in Rajasthan (5.17M/ha. And 4.28M/tonne) but Haryana gives highest average yield per hectare (1769 kg/ha.). Blast incited by Pyricularia setariae Nisikado is prevalent in many pearl millet growing regions of the country. Severe infection reduces fodder value considerably. Protein is an important ingredient of the fodder but the information regarding the effect of blast severity on protein content of leaves is not known. The disease has occupied key position in the reduction of pearl millet fodder quality in northern Madhya Pradesh. Pearl millet blast increases nitrogen (N2) and protein content in the infected leaves. Regression studies indicate 12.8% protein in the leaves of healthy pearl millet hybrid which may increase by 0.095% due to per unit increase in the blast severity.Keywords

The earth’s atmosphere is a complex mixture of many gases and their observations are incorporated in chemistry-climate models. Atmospheric observations have been the backbone of recent progress in atmospheric science, particularly about our understanding of the sun–atmosphere interaction causing chemical and radiative forcing linked to the environment and climate change. In terms of technology, there has been significant progress in both in situ and remote sensing measurements of several variables in the lower atmosphere. Among them, trace gases play an important role in climate change and several environmental problems. The recent progress in both in situ and remote sensing-based instrumentation has enabled researchers to study various atmospheric processes in great detail. For example, gas chromatography-based instrumentation provides detection from simple to complex species present in the atmosphere at very low concentrations. The laser-based spectroscopic instruments are emerging tools for fast response measurements of trace gases, which are important to understand rather short-term processes. The proton transfer reaction-mass spectrometry is regarded as one of the best technologies for the detection of numerous but specific types of trace gases, namely volatile organic compounds. However, there are advantages and disadvantages of any instrument in terms of quality of data, comprehensiveness and cost. In this article, we discuss the recent progress in instrumentation used for the measurement of trace gases in the lower atmosphere utilizing space, aircraft and satellitebased platforms as well as some laboratory techniques. We also briefly highlight the progress made during the past couple of decades, present status and future scenarios of trace gas measurements in the South Asia region.Keywords
