    Abstract Background: Streptococcus pneumoniae is leading bacterial cause of community acquired pneumonia and according to World Health Organization, responsible for 14 % death in children. There is effective vaccine available against Streptococcus pneumoniae. Hence the primary objective was to isolate Streptococcus pneumoniae from nasopharyngeal swabs in children aged 2-59 months with and without community acquired pneumonia and to assess their serotypes.
    Methods: This case-control study was conducted in tertiary teaching institutes in northern India. Hospitalized children, aged 2-59 months, with World Health Organization-defined community acquired pneumonia were included as cases. Age matched healthy controls were recruited from immunization clinic. All enrolments were done after written informed parental consent. Nasopharyngeal swabs were taken from both cases and controls, and were cultured on 5 % sheep blood agar with gentamycin plate for growth of Streptococcus pneumoniae and incubated in a jar at 37
    Results: From March 2017 to December 2022, 2693 children (1910 cases and 783 controls), were recruited. The median age of cases was 7 months and controls 10 months. Almost all the cases had received antibiotics prior to hospitalization. Streptococcus pneumoniae positivity in nasopharyngeal swab was 8.1 % in cases, of which 56.8 % were vaccine serotypes and 23.6 % in controls, of which 37.8 % were vaccine serotypes. Adjusted odds ratio of isolating vaccine serotypes among cases as compared to controls was 1.77 (95 % CI, 1.09-2.88).
    Conclusion: Streptococcus pneumoniae isolation from nasopharyngeal was found to be in lower proportion in cases as compared to control, though colonization with vaccine serotypes was higher in cases as compared to control. Therefore, pneumococcal vaccine coverage must be increased to prevent community acquired pneumonia.

    Abstract The main objective of this work is to clear the economic condition of heat pipe based solar water heating technology in India. For this, a techno-economic analysis has been carried out which offers the facts for the investment in this sector. A computation model has been developed by the amalgamation of the Monte Carlo Technique (MCT) and Multi-energy/economic relations that take into consideration the risks and integrated uncertainties of different variables. The results reveal that LCWH and PP are found to be lowest for Zone-V and will require the least collector area. Since the highest solar radiation in Zone-V eventually reduces the ratio of annual energy demand to annual solar radiation. Thus Zone-V is the most favorable place for the installation of the solar water heater. The mean values of LCWH, NPV, and PP are found to be 5.14 INR/kWh, 663788.48 INR, and 5.84 years respectively. However, values of LCWH, NPV, and PP through optimization were found to be lesser by 25–33%, higher by 9–28%, and lower by 37–47% respectively. The MCT is efficient to defeat discrepancies in the results of conventional techniques by taking into consideration the range of states according to their probability to offer more accurate forecasts.

    Abstract Crotalaria nicobarica, a new species from Andaman and Nicobar Islands, India is described and illustrated along with conservation status. This new species closely resembles C. lunulata Heyne ex Wight and Arn., C. paniculata Willd. and C. ramosissima Roxb. which occurs in western and eastern peninsular India and occupies forest edges and cut‐slopes of hillocks, but the new species is distinct in morphology of vegetative and reproductive characters from all previously known species. Based on its hairyness, persistent bracts and bracteoles, silky pubescence of vexillum and style, and oblong stalked pods, the species is referred to C. sect. Crotalaria.

    Abstract: The present investigation was carried out on tomato under protected culture using sixteen treatments having four levels each of silicic acid (0.0%, 0.1%, 0.2% and 0.3%) and Novel organic liquid nutrient (NOVeL) (0.0%, 1.0%, 1.5% and 2.0%) to find out the ...

    Abstract The present investigation was carried out on tomato under protected culture using sixteen treatments having four levels each of silicic acid (0.0%, 0.1%, 0.2% and 0.3%) and Novel organic liquid nutrient (NOVeL) (0.0%, 1.0%, 1.5% and 2.0%) to find out the effect of silicon and nutrient spray on growth, yield and quality parameters. The analysis of data revealed significance of individual effect of silicic acid on yield parameters under study. The effect of NOVEL was limited to few characters, while interaction effect was found to be significant for majority of the traits. Use of silicon as silicic acid (0.3%) gave higher number of fruits per plant (49.68) and correspondingly higher marketable yield per m² (10.82 kg). Different levels of NOVEL were found to influence pericarp thickness and shelf-life significantly and 1.5% NOVEL showed maximum pericarp thickness (6.75 mm) and shelf-life (15.51 days). Silicic acid and NOVeL (0.3% + 1.5%) interactively have maximum incremental leaf area (151.27 cm²) at 60 DAP, fruit firmness (4.38 kgcm⁻²), total soluble solid (4.93 ᵒBrix) and minimum physiological loss in weight (10.71%), whereas, silicic acid and NOVeL (0.2% + 2.0%), (0.2% + 0.0%), (0.3% +0.0%) recorded maximum incremental leaf area (151.27 cm², 117.75 cm² and 101.90 cm², respectively) at 40, 120 DAP and at final harvest. Moreover, maximum vitamin A (1124.70 IU) and lycopene content (4.52 mg/100g) was recorded due to the interaction effect of silicic acid and NOVeL (0.2% + 0.0 and 0.0+ 1.5%, respectively).

    Abstract Aonla fruits are not consumed freely in fresh form because of its astringent taste. Therefore, various cultivars of aonla were screened for their suitability for processing into different products and accordingly the fruits of cultivar Chakaiya were used for preparation of fruit beverages (RTS and squash) and NA-7 for making preserve, pickle and sauce. Observations on vitamin C (ascorbic acid), total soluble solids, acidity, browning and organo-leptic quality of these products were recorded during storage at monthly interval. The vitamin C content of these products decreased continuously with the storage period. The total soluble solids of RTS, squash and preserve increased slightly during storage but in pickle and sauce it started declining after two months of storage. Acidity content of aonla products increased with the storage period except pickle where it declined after three months of storage. A progressive increase in browning of aonla products was also observed with the storage period. Organoleptic score of the aonla products declined continuously during storage. The acceptable quality of aonla preserve and pickle was maintained upto nine months, while sauce was acceptable upto six months and beverages (RTS and squash) up-to four months of storage.

    Abstract Metal, carbon and conducting polymer nanoparticles are blended with organic phase change materials (PCMs) to enhance the thermal conductivity, heat storage ability, thermal stability and optical property. However, the existing nanoparticle are expensive and need to be handle with high caution during operation as well during disposal owing to its toxicity. Subsequently handling of solid waste and the disposal of organic PCM after longevity usage are of utmost concern and are less exposed. Henceforth, the current research presents a new dimension of exploration by green synthesized nanoparticles from a thorny shrub of an invasive weed named Prosopis Juliflora (PJ) which is a agro based solid waste. Subsequently, the research is indented to decide the concentration of green synthesized nanoparticle for effective heat transfer rate of organic PCM (T
