The study of the interactions between Sava River and Zagreb aquifer system (Croatia) using water stable isotopes

Water stable isotopes were used to investigate hydrological pathways and interactions between surface water and groundwater in the Zagreb aquifer system (Croatia). δ2H and δ18O values indicate a spatial variability of the influence of individual groundwater sources inside the aquifer – local precipitation and the Sava River water. Fractions of surface water in groundwater strongly depend on fluctuations of the river water level and less on the distance from the Sava River. These data extend our understanding of groundwater flow in the Zagreb aquifer system, interactions between Sava River water, local precipitation and groundwater. The results of the research allow more precise monitoring plans and definition of the sanitary protection zones of the well fields in the future.
The respiratory area of the gills of some teleost fishes in relation to their mode of life

From computations (by means of graphic interpolation and graphic integration) of the respiratory area, and transposition of these values to a respiratory area of a standard fish of 200 g (A200 value), it could be made plausible that the relation between respiratory area and mode of life of the fishes mentioned in this paper (Cod, Plaice, Conger, Flounder, Dab and Pike) fits in with the general pattern found in an earlier paper, although intraspecific differences were sometimes considerable. In comparison with A200 values of other species, the Cod has a respiratory area that fits in with his mode of life and that of other typical sprinters. The Flounder has a considerably larger respiratory area than Plaice and Dab. Flounder feeds mainly on small fishes, while Plaice and Dab feed on molluscs and worms. Conger has to be considered a crawler. The Pike, as a typical sprinter, shows nevertheless large differences in its A200 values. It was known already that freshwater biotopes do not allow fishes to develop into typical stayers. Thus, large differences between freshwater sprinters and crawlers can hardly be expected. The relation between respiratory area and body surface cannot be used in a comparison between fishes of different species.
Detection of Cell Surface Ligands for the γδ TCR Using Soluble TCRs1

The natural ligands recognized by γδ TCRs are still largely unknown, in part because immunization does not normally result in Ag-specific γδ T cell responses. Taking advantage of an established ligand for a particular γδ TCR, we demonstrated that a multimerized recombinant form of this γδ TCR can be used like a mAb to specifically detect its own ligand. Using the same approach for more common γδ TCRs whose ligands remain unknown, we detected on certain cell lines molecules that appear to be ligands for three additional γδ TCRs. One of these represents the mouse Vγ6/Vδ1 invariant γδ TCR, which predominates in the female reproductive tract, the tongue, and the lung, and other tissues during inflammation. The second represents the closely related Vγ5/Vδ1 invariant γδ TCR expressed by most epidermal T cells. The third is a Vγ1/Vδ6. 3 TCR, representative of a variable type frequently found on lymphoid γδ T cells. We found evidence that ligands for multiple γδ TCRs may be simultaneously expressed on a single cell line, and that at least some of the putative ligands are protease sensitive. This study suggests that soluble versions of γδ TCRs can be as tools to identify and characterize the natural ligands of γδ T cells.

Stochastic model of mating decision control in yeast through the scaffold protein Ste5

High throughput technologies in genetics laid the foundations for systems and synthetic biology. Systems and synthetic biology became an important topic in biology research. It was used in research to investigate the behavior and relations of all elements in biological systems while it was functioning. The intracellular signal transduction pathway, where the haploid yeast Saccharomyces cerevisiae responds to the mating pheromone in its surroundings, is believed to be one of the best understood and studied signaling pathways in eukaryotes. In Malleshaiah et al. (2010) it was introduce a general model of the switch-like mating decision in the haploid yeast S.cerevisiae. The general model consisted of the Ptc1, Ste5, and Fus3 circuit with two-stage binding that exhibited zero-order ultrasensitivity. The model of a switch-like mating decision in the haploid yeast S. cerevisiae was modified in order to perform both deterministic and stochastic analysis. Deterministic analysis was conducted with mean measurements. Furthermore, stochastic simulations of the modified model were conducted. Hence, it was possible to analyze the fluctuations in the system by calculating the mean, standard deviation, coefficient of variation and fano factor. This gave an indication of the switch. It was calculated the mean values of free and bound Ste5 molecules and the amount in every single complexes. Due to an increase of the Ste5 and Fus3 molecules, the mean of free and bound Ste5 molecules were changed. By calculating the mean of bound Ste5 molecules in single complexes, the distribution of bound Ste5 molecules was about the same. The parameter values were conducted from literature, which were used in both the deterministic and stochastic simulations. The system was not affected by kinetic rate changes and thereby robust.

A neotype for Anopheles (Cellia) sundaicus (Rodenwaldt), the nominotypical member of a malaria vector species complex, is selected from the progeny of a female collected at Pandan Beach near Lundu, Sarawak, Malaysia. Siblings of the neotype and other topotypic specimens are used to characterize and fix the morphological and molecular identity of the species as a foundation for systematic studies of the species complex. The species is described and illustrated in the adult, pupal and larval stages, and DNA sequence data are included for the mitochondrial cytochrome c oxidase I (COI) gene and the nuclear ITS‐2 region.
Characterization of local goats of Chhattisgarh plains

There are 23 descript breeds of goat in India. However there is no recognized breed of goat registered by Chhattisgarh state hence requires systematic study for their characterization. The present study was undertaken to establish the norms of different physical characteristics, reproductive and productive performance traits and haematological profile of local goats of Chhattisgarh plains. Information was collected from Raipur, Durg, Rajnandgaon and Kanker districts of Chhattisgarh plain region. The average measurement for body weight, body length, height, ear length, face length, horn length and tail length for adult male were 31.05±0.49kg, 71.26±0.6, 74.44±0.91, 45.35±0.71, 16.14±0.21, 19.47± 0.18, 15.85±0.43 and 16.05 cm respectively. The corresponding values in adult female were 24.55±0.47 kg, 61.13±0.90, 64.74±0.73, 37.37±0.52, 15.74±0.24, 18.41±0.18, 11.72±0.57, and 14.58±0.22 cm respectively. The mean values for the reproductive performance traits i.e. age at first mating in male, age at first mating in female, age at first kidding and kidding interval were observed as 184±0.05, 216±0.04, 370±0.4 and 184±0.03 days, respectively, and average litter size 1.5. The mean values for the productive performance traits daily milk yield, total lactation milk yield and lactation length were recorded as 307.25±13.16 ml, 32.29±2.65 litres, and 105.75±2.48 days, respectively. Different haematological parameters such as haemoglobin, packed cell volume, total erythrocytes count, total leukocytes count, mean corpuscular haemoglobin, mean corpuscular volume and mean corpuscular haemoglobin concentration were considered and value estimated as 9.35±0.20 (g%), 28.9±0.66 (%), 8.45+0.17 (million/μl), 9,660±256.33 (thousand/μl), 9.1± 0.22 (pg), 27.79±0.0 (fl), and 32.39±0.27(%) respectively. Hence this study was aimed to phenotypically characterize the local goat in view of establishing a database for the breed and undertaking conservation programme for preserving rich indigenous genetic resources biodiversity.

The influence of pH and temperature on endogenous phytase activity and on hydrolysis of inositol hexa phosphate in lentil, faba bean and pea seeds.

The study was conducted to determine the influence of pH and temperature on endogenous phytases activity and to investigate the influence of pH and temperature of soaking on hydrolysis of inositol hexaphosphate in lentil, pea, and faba bean seeds. In the first experiment, the sodium phytate was hydrolyzed by phytase extracted from the germinated seeds and the released inorganic phosphorus was measured. The second experiment relied on measuring the changes in seed contents of inositol phosphates as affected by soaking-activated phytases at 37°C, 45°C and 55°C and pH 4.0, 5.0, 6.4, 7.0 and 8.0. In both experiments, the highest activities of endogenous phytase were found in pH 5.0 for lentil, pH 4.0 for faba bean and pH 7.0 for pea, and the temperature of 45°C appeared to be the most suitable for enzyme activity, for all examined species. The obtained results, proved by two experiments, can indicate that above mentioned pHs and temperatures are convenient for optimal activity of phytase enzyme in examined seeds, what can be used in the technology of fodder and food production.
Automatic digital image analysis for identification of mitotic cells in synchronous mammalian cell cultures.

: Mitotic frequency in a synchronous culture of mammalian cells was determined fully automatically and in real time using low-intensity phase-contrast microscopy and a newvicon video camera connected to an EyeCom III image processor. Image samples, at a frequency of one per minute for 50 hours, were analyzed by first extracting the high-frequency picture components, then thresholding and probing for annular objects indicative of putative mitotic cells. Both the extraction of high-frequency components and the recognition of rings of varying radii and discontinuities employed novel algorithms. Spatial and temporal relationships between annuli were examined to discern the occurrences of mitoses, and such events were recorded in a computer data file. At present, the automatic analysis is suited for random cell proliferation rate measurements or cell cycle studies. The automatic identification of mitotic cells as described here provides a measure of the average proliferative activity of the cell population as a whole and eliminates more than eight hours of manual review per time-lapse video recording.
Fryxelliella sepulvedana sp. nov. (Triceratiaceae, Bacillariophyta), a rare species from the Mexican Pacific coasts

Fryxelliella sepulvedana n. sp. , from the Mexican Pacific coasts is the second species hitherto known for the genus. As in the other Fryxelliella species, F. sepulvedana has a sipho marginalis bearing triangular apertures, three ocelli and three rimoportulae equidistantly placed near the margin of the valve. The ocelli are the most important diagnostic features of F. sepulvedana as they are large (3.5-5.0 μm in diameter) and are located in the submarginal region, at least four areolae distant from the valve margin. They differ from those of F. floridana, the other species in the genus, where the ocelli are marginal and are in contact with the sipho marginalis. While F. floridana was found in the Atlantic Ocean, F. sepulvedana was recorded in the eastern tropical Pacific. The new species was found in different coastal localities of Mexican Pacific Ocean, all close to the coast, and sampled in the water column.
Sensitivity of an idealised subtropical gyre to the eastern boundary conditions

The flow pattern of the North Atlantic Subtropical Gyre (NASG) is simulated using a highly idealised one-layer quasi-geostrophic wind-driven model. The novel feature of the model is the specification of the eastern boundary conditions. This is an upwelling favourable region with a quasi-permanent southward flowing coastal jet, which is fed by the eastern branch of the Canary Current. The corresponding boundary conditions are non-zero normal flux and constant potential vorticity, the latter being consistent with the generation of anticyclonic vorticity by the coastal jet. We examine the sensitivity of the model to the eastern boundary conditions and compare the results with recent observations for the region.
Influence of Indian Ocean Dipole Phenomena Towards the Eddy Variability in Southern Java Ocean

The phenomenon of Indian Ocean Dipole (IOD) can influence the variability of eddy in the Southern Java Ocean (SJO). The purpose of this research is to know the characteristics of eddy in the SJO at the time of the IOD condition. The research was conducted in Eastern Indian Ocean (EIO), South of the Java Island by coordinate 0o S – 15o S and 90o E – 120o E. The data used in this research is currents data, sea surface height (SSH) data, and temperature data from HYCOM, and Dipole Mode Index (DMI) data from Japan Marine Science and Technology (JAMSTEC). Methods used for detecting eddy is using the Automated Eddy Detection (AED) method. The results of this research show that the IOD phenomena affect the variability of eddies in the SJO, this is evidenced by the difference of the total eddies is generated at the time of normal conditions and at the time was going to the phenomenon of IOD. Total average eddies on IODM (+) conditions is 153 and on IODM (-) conditions is 144. IODM (+) conditions could cause the value of a central point of sea surface height (SSH) and sea temperature is lower than the normal conditions, the opposite IODM (-) conditions can cause the value of a central point of SSH and sea temperature is higher than the normal conditions.
The Proliferation of Smartphones and their Effects on Improving the Vocabulary of Indonesian Learners of Arabic

: This article aims to describe the use of the smartphone as a media to improve the mastery of students’ Arabic vocabulary (mufradat). The participants in this study are students who are studying Arabic for the second and the third years of the Arabic at Hasanuddin University. The number of participants is 32 and 33 students for the respective batch. The researcher has created a mufradat database in an html-based interactive application, which is easily accessed to via a smartphone or tablet. The testing of media effectiveness in improving mufradat mastery is done through two experimental and control groups. Both groups can use PC facilities available at the computer lab to access mufradat database. Both groups can also use their smartphones to access the online interface. The difference is only in the memorization report of the mufradat and the competency test. Experimental group uses smartphone media to report their memorization, while control group reports theirs through a daily vocabulary record and was tested by using written test. The results show that experimental group indicates better mastery than control group. The average memorization of the experimental group is 1432 words while control group only reaches an average of 532 words.
Biomechanical modelling of long bones and body mass estimation in modern and fossil species

The thesis presented herein utilizes a variety of methods to address the biomechanical function of vertebrate hind limb bones in both modern and fossil species. In an innovative application of beam theory, the maximum force a long bone is capable of withstanding before yield is calculated under a variety of simplified loading conditions for a phylogenetically diverse sample of modern birds and mammals. In doing so, new insights are gained into the combined role of limb bone geometry and load vector in achieving mass-invariant safety factors under static loading. In particular, the avian femur is found to scale with sufficient allometry such that no postural modification is required to maintain constant safety factors across several orders of magnitude in body mass. In a methodological study, two techniques for estimating stress (simple beam theory and finite element analysis, FEA) are compared across a sample of morphologically diverse long bones. The extent to which stress estimates derived from the two modelling techniques diverge is found to correlate to aspects of the underlying bone morphology such as shaft curvature and cross-sectional asymmetry, and important recommendations are made regarding the appropriate application of both methods to skeletal material. A novel ? convex hull? volumetric mass prediction technique for fossil birds is applied to two species of extinct moa (Dinornithiformes) from New Zealand. The resulting mass estimates are incorporated into a FEA study of the femora and tibiotarsi of modern ratites and moa. The ? stout southern? moa (Pachyornis australis) is confirmed as possessing extremely robust limbs, whilst the ? terrible robust? moa (Dinornis robustus) is found to possess equally, if not less, robust limb bones than those of modern ratites. The results are subsequently interpreted in the context of moa habitat range and shared ancestry. Finally the convex hull mass estimation technique is extended to modern primates, and the scaling of body mass with convex hull volume is compared across birds, primates and non-primate mammals. The allometric scaling of convex hull volume in birds and primates is considered in light of interspecific variation in muscle volume, body fat and integumentary structures, and is particularly relevant to those reconstructing the soft-tissue architecture of fossil species.
Nutrient Status and Ameliorating Effects of Poultry Droppings on Soil pH and Sustainable Production of Garden Egg

Sustainable production of crops on tropical soils requires soil amendment to remediate soil acidity status and raise fertility level. Industrial lime and inorganic fertilizers are either not available or too expensive to buy. This study was carried out with the objective of investigating the effects of poultry droppings on soil acidity amelioration and increased fertility for sustained production of garden egg ( Solanum aethiopicum L.). The field trials were conducted at the Teaching and Research Farms of the University of Agriculture, Makurdi, and the Faculty of Agriculture, Cross River University of Technology, Obubra in 2009 and 2010. Two varieties of African garden egg (Gilo and Kumba) and three rates of poultry droppings (5, 10 and 15 t ha -1 ) were in factorial combinations. The experiment was laid out in a Randomized Complete Block Design with three replications. The results obtained showed that all rates of the manure reduced the soil pH within 30 days after incorporation in both years and locations. At 60 days after application, and up to 140 days after incorporation, all manure rates increased the soil pH in both locations and years. The highest increase occurred with 15 t ha -1 poultry droppings at 140 days after incorporation. With no manure application, there was a steady decrease in pH up to the harvest time. All manure rates significantly (P<0.05) increased the yield of the garden egg varieties over when no manure was used. Poultry droppings at 15 t ha -1 produced the highest fruit yield in both years and locations. The crop yields were significantly (p<0.05) higher in Makurdi than Obubra in both years. Yield for 2010 was significantly higher than 2009 in both locations. Poultry dropping at the rate of 15 t ha -1 may be used to remediate soil pH and improve fertility for sustainable production of garden egg in the Guinea savanna or the Rainforest agro-ecologies.
Dependence of the ghostbursting model’s dynamical states on the current injected into the dendritic compartment and the ratio of somatic to total surface areas

The ghostbursting model is a mathematical model that describes the dynamics of the electrical excitability of the weakly electric fish Apteronotnus leptorhynchus. This model is described by a system of nonlinear ordinary differential equations. The present study focuses on two system parameters of the model (i.e., the current injected into the dendritic compartment and the ratio of somatic to total surface areas); in addition, a computer simulation analysis of the model is performed. By changing these parameter values, the dynamical states of the model in the twodimensional parameter space are revealed. Mathematics Subject Classification: 37N25, 92C20 PACS: 05.45. -a, 87.19. ll.
Overexpression of the Nocardia lactamduransα‐Aminoadipyl‐Cysteinyl‐Valine Synthetase in Streptomyces lividans

Formation of the tripeptide δ-(l-α-aminoadipyl)-l-cysteinyl-d-valine (Aad-Cys-Val) is catalyzed by a multienzyme peptide synthetase encoded by the pcbAB gene in producers of β-lactam antibiotics. The pcbAB gene of Nocardia Lactamdurans was overexpressed in Streptomyces Lividans giving a high Aad-Cys-Val synthetase activity. The synthetase was purified 2785-fold to near homogeneity showing a molecular mass of 430 kDa by SDS/PAGE. The protein was identified in the gels with antibodies to Aad-Cys-Val synthetase and by the formation of aminoacyl-synthetase thioester complex with [14C]valine. The purified synthetase used α-aminoadipic acid or its lactam 6-oxopiperidine 2-carboxylic acid but was unable to use piperideine 6-carboxylic acid or pipecolic acid as substrates to form Aad-Cys-Val. l-Cysta-thionine, (2-amino-2-carboxyethyl)-l-homocysteine, was used as substrate and formed Aad-Cys-Val with the same efficiency as l-cysteine. The product of the reaction eluted with authentic Aad-Cys-Val. The synthetase preparation was able to hydrolyze l-cystathionine by a pyridoxal-phosphate-independent mechanism which is not inhibited by propargylglycine, to form Aad-Cys-Val.
