Characteristics of the Cross-Sectional Vorticity of the Natural Spawning Grounds of Schizothorax prenanti and a Vague-Set Similarity Model for Ecological Restoration.

Schizothorax prenanti is an endemic fish in the mountain rivers of southwestern China with unique protection value. To further explore the vortex motion of hydraulic habitats, which is closely related to the fish breeding process, the cross-sectional vorticity was used to evaluate the hydraulic conditions of the natural spawning habitat of S. prenanti.

Bioaccumulation and tolerance characteristics of a submerged plant (Ceratophyllum demersum L.) exposed to toxic metal lead.

A hydroponic study was conducted to investigate the lead bioaccumulation and tolerance characteristics of Ceratophyllum demersum L. exposed to various lead concentrations (5-80 μM) for 7, 14 or 21 days. Lead accumulation increased with increasing concentrations of metal in the solution, to a maximum accumulation of 4016.

A combination of solvent extraction and freeze thaw for oil recovery from petroleum refinery wastewater treatment pond sludge.

A combination of solvent extraction and freeze thaw was examined for recovering oil from the high-moisture petroleum refinery wastewater treatment pond sludge. Five solvents including cyclohexane (CHX), dichloromethane (DCM), methyl ethyl ketone (MEK), ethyl acetate (EA), and 2-propanol (2-Pro) were examined. It was found that these solvents except 2-Pro showed a promising oil recovery rate of about 40%, but the recycling of DCM solvent after oil extraction was quite low.

A new species of gecko of the genus Cnemaspis Strauch, 1887 from the Western Ghats, India.

A new species of the gekkonid genus Cnemaspis is described from the lateritic plateau of the northern Western Ghats of Maharashtra, western India. The new species is diagnosed by the following suite of characters: small sized Cnemaspis, SVL less than 35 mm (21.52-33.

A new species of scorpion of the genus Neoscorpiops Vachon, 1980 (Scorpiones: Euscorpiidae) from India.

A new species of scorpion of the genus Neoscorpiops Vachon, 1980 is described from Northern Maharashtra. Neoscorpiops maharashtraensis sp. nov.

Preliminary review of Indian Eumenophorinae (Araneae: Theraphosidae) with description of a new genus and five new species from the Western Ghats.

The theraphosid spider genera Heterophrictus Pocock, 1900 and Neoheterophrictus Siliwal & Raven, 2012 are rediagnosed in this paper and a new genus, Sahydroaraneus gen. nov. is described from Southern Western Ghats.

Reduction of the livestock ammonia emission under the changing temperature during the initial manure nitrogen biomineralization.

Experimental data were applied for the modelling optimal cowshed temperature environment in laboratory test bench by a mass-flow method. The principal factor affecting exponent growth of ammonia emission was increasing air and manure surface temperature. With the manure temperature increasing from 4°C to 30°C, growth in the ammonia emission grew fourfold, that is, from 102 to 430 mg m(-2)h(-1).

A complex evaluation of the asymmetry of dermatoglyphs.

Altogether 20 traits of the fingers, 22 traits of the palm and 8 traits of the sole were taken into consideration, on both sides of the bodies of 1652 males and 1628 females. Numbers of asymmetrical variants of the traits within the whole complex of 25 pairs of traits were determined individually. In the case of descriptive traits, asymmetry was deemed to be the occurrence on either side of the body of non-identical variants of the traits, and for quantitative traits, the absolute difference of at least two ridges was accepted.

Microbial air contamination in indoor environment of a university library.

The present study was aimed at evaluating the number of bacteria and mould fungi in the indoor and outdoor environment of Toruń University Library. The sampling sites were located in the rooms serving the functions typical of libraries (i.e.

Tree rings of Scots pine (Pinus sylvestris L.) as a source of information about past climate in northern Poland.

Scots pine (Pinus sylvestris) is a very common tree in Polish forests, and therefore was widely used as timber. A relatively large amount of available wood allowed a long-term chronology to be built up and used as a source of information about past climate. The analysis of reconstructed indexed values of mean temperature in 51-year moving intervals allowed the recognition of the coldest periods in the years 1207-1346, 1383-1425, 1455-1482, 1533-1574, 1627-1646, and 1694-1785.

Continuous treatment process of mercury removal from aqueous solution by growing recombinant E. coli cells and modeling study.

A continuous treatment process was developed to investigate the capability of genetically engineered E. coli to simultaneously accumulate mercuric ions and reproduce itself in a continuous stirred tank reactor (CSTR) system. The influence of dilution rate and initial Hg(2+) concentration on continuous process was evaluated.
