Artificial recharge to groundwater is steadily assuming importance in the wake of the decline in water level in several parts of the country. Recharge through an injection well is the most suitable option of artificial recharge for semi-confined and confined aquifers, especially in urban and industrial areas as it requires little space. Recharging capacity of a well is an important criterion in deciding the number of recharge structures required for large-scale planning of artificial recharge.

With the rapid population growth, ecological pressure caused by human activities on rivers is growing. Decision makers are often faced with the dilemma of how to maintain economic growth while also maintaining the resources of a river and its environment. In this study, a model has been proposed for the assessment of river–human relationship. The method establishes a complete index system to quantify the abstraction of river–human relationship and evaluation.

Zinc (Zn) deficiency is the most widespread micronutrient deficiency in crop plants and humans. Low intake of Zn through diet appears to be the major reason for the widespread prevalence of Zn deficiencies in human populations. Application of Zn fertilizer in soil having low Zn increased the grain yield in wheat up to 6.4–50.1%. However, soil Zn application increased the grain yield of rice only up to 7.2–14.8%.

A study was taken up to identify annual changes in temperature. For this study, daily (maximum and minimum) temperature data for 45 years (1969–2013) prepared by the India Meteorological Department, Pune were used. The identification of change was based on statistical trend analysis. From the analysis, it can be concluded that the dominant tendency over the India land mass is of warming, and colder months of the year show more warming.

Invasion is an ecological phenomenon of introduction of organisms to areas outside their native ranges. It concerns all aspects relating to their transport, establishment and spread in a new region . An invasive species causes imbalance to the ecosystem by monopolizing food and spatial resources and consequently disrupting the native community . Biological invasion is presently one of the major sources of stress to the coral reef habitats, which harbour 25% of total marine biodiversity and contribute to 10% of total fishery production .

Many captive populations of birds and mammals are not likely to reach sustainability due mostly to breeding problems. Identifying the conditions under which breeding problems and poor population growth are likely to occur and establishing more appropriate conditions, therefore, will be a necessary prerequisite for future successful conservation breeding and the long-term survival of captive populations. This article analyses the basic approaches and concepts of management programmes for captive mammals.

Small cell lung cancer (SCLC) comprises approximately 15–18% of all lung cancers worldwide. SCLC is the most aggressive subtype of lung cancer and is characterized by rapid doubling time, high growth fraction, and early widespread metastasis. Despite high response rates to initial treatment, SCLC usually relapses and becomes refractory to treatment within one year. The median survival is 14–20 months for limited SCLC and 9–11 months for extensive SCLC. These statistics highlight the need for new tools to aid in diagnosis and prevention.

Revelations that Volkswagen, the world’s biggest car maker, rigged its emissions testing in the United States to circumvent regulations and boost its sales have sent shock waves through the car industry. On 22 September, the company admitted that it had used special software to lower emissions during laboratory tests of some of its diesel vehicles.

We examine the potential for geographic smoothing of solar photovoltaic (PV) electricity generation using 13 months of observed power production from utility-scale plants in Gujarat, India. To our knowledge, this is the first published analysis of geographic smoothing of solar PV using actual generation data at high time resolution from utility-scale solar PV plants.

Przewalski’s horses (PHs, Equus ferus ssp. przewalskii) were discovered in the Asian steppes in the 1870s and represent the last remaining true wild horses. PHs became extinct in the wild in the 1960s but survived in captivity, thanks to major conservation efforts. The current population is still endangered, with just 2,109 individuals, one-quarter of which are in Chinese and Mongolian reintroduction reserves. These horses descend from a founding population of 12 wild-caught PHs and possibly up to four domesticated individuals.
