VOLUMETRIC PROPERTIES OF ACRYLONITRILE+ETHANOL MIXTURE OVER TEMPERATURE RANGE FROM (293.15 TO 323.15) K AT AMBIENT PRESSURE

Измерены плотности бинарной смеси акрилонитрила в этаноле во всем концентрационном диапазоне и в температурном интервале 293,15-323,15 К при внешнем давлении (87,9 кПа). Плотности растворов измерены с помощью колебательно-резонансного денсиметра Anton Paar DMA 4500 с точностью измерения плотности и температуры соответственно ±5·10 г/см и ±0,03 К. Рассчитаны обьемные параметры: избыточные молярные объемы, кажущиеся молярные объемы, парциальные и парциальные избыточные молярные объемы. Избыточные молярные объемы описаны уравнением Редлиха-Кистера. Параметры уравнения Редлиха-Кистера и стандартные отклoнения избыточных молярных обьемов также рассчитаны. Величины избыточных молярных объемов отрицательны во всем концентрационном диапазоне в более низких температурах, но с ростом температуры от 293,15 К до 323,15 К отрицательные отклонения уменьшаются. Результаты интерпретируются на основе сильного взаимодействия между нитрильной группой акрилонитрила и OH-группой этанола посредством водородной связи. Однако сигмоидальная форма зависимостей избыточных молярных объемов от мольных долей этанола от положительных до отрицательных значений указывает на различные взаимодействия в зависимости от состава бинарных смесей. Более того, такая форма зависимости избыточных молярных объемов от мольной доли при низких концентрациях этанола указывает на его самоассоциирующие действия, в результате которых в этих же концентрациях преобладают гомоассоциаты акрилонитрила с диполь-дипольным взаимодействием, а также гомоассоциаты этанола с водородными связями. В работе приведены новые данные по температурной зависимости плотностей и объемных свойств бинарного раствора акрилонитрил-этанол в температурном интервале 293,15-323,15 К. Полученные результаты сопоставлены с литературными данными.
Study of p53, Pcna, Ki67 and Micronuclei Related to Genotoxic Damage for Risk Categorization in Pre- Malignant Oral Lesions

In this prospective study, search for high risk cases of premalignant oral lesions were attempted through evaluation of oncoprotein expression, cell proliferation and micronuclei. Materials and methods: A total 50 cases of oral leukoplakia were diagnosed and adequate controls along with detailed history were included in this study. Study of tumour markers like p53, PCNA and Ki-67 were done immunohistochemically on tissue sections. Study of micronuclei was performed by feulgen staining method. Results: The mean age of the 50 cases were 44.48 ± 9.76 and median age was 50 years. There were 45 male cases (90%) and 5 female cases (10%). There were 26 non dysplastic (52%) and 24 dysplastic cases (48%). The smokers consist of 25 cases (50%) and other addictions (betel quid chewers, ghutka, khaini, alcohol etc.) had 24 cases (48%) and 1 case was non addict (2%). Out of 25 cases of smokers, 20 (80%) were positive in case of p53, 19 (76%) were positive in case of PCNA and 17 (68%) were positive in case of Ki67. Out of 24 cases of other addictions, 16 (66.67%) cases were positive in case of p53, 13 (54.17%) positive cases in case of PCNA and16 cases (66.67%) were positive in case of Ki67.The smokers had 0.51 ± 0.21 micronuclei frequency whereas other addiction groups had 0.24 ± 0.10. Conclusion: The histopathological risk assessment of these cases is inconclusive and thus p53, PCNA, Ki67 and micronuclei evaluation are needed for risk categorization.
Protein self-encapsulation: A mechanism involved with colloidal flocculation in citrus fruit extracts†

Cloud stability in citrus fruit aqueous peel extract (PEX) and the derived serum (SPEX) was studied with respect to endogenous coagulants and the possible involvement of soluble pectin as stabilising agent. Heat treatment of the pectin-degraded SPEX induced the appearance of turbidity as a result of protein coagulation, particularly in the pH range of 3.5–4.5, whereas only slight coagulation occurred without heat treatment. The pectin in non-degraded SPEX therefore inhibited heat coagulation of most of the protein present. Incubation of PEX itself with exogenous depolymerising pectinase (DP) slightly increased its transmittance, and subsequent heat treatment clarified the suspension within a short time, especially at pH 2.5–4.5. Under the electron microscope, heat-coagulated proteins from DP-incubated SPEX appeared as dispersed amorphous bodies showing two main types of pattern; the coagulate from a PEX preparation of high oil content appeared as ultramicro-droplets of oil encapsulated within coagulated proteins. The evidence indicates that soluble pectin in PEX preparations affects cloud stability by preventing the coagulation of heat-denatured proteinaceous components; once the pectin is degraded by endogenous and exogenous DP, protein coagulation occurs rapidly on heat treatment, resulting in co-precipitation of the other encapsulated colloidal bodies.
MOLECULAR ANALYSIS OF HS-111 AND 3`HS1 VARIATIONS IN β-THALASSEMIA INTERMEDIA PATIENTS WITH HIGH LEVELS OF HBF

Objective: To study the possible association between high levels of fetal haemoglobin (HbF) in β-thalassemia intermedia patients and HS-111 and 3`HS1 sequence variations. Materials and Methods: In this study, the 3' HS-1 and HS-111 regions of 30 s-thalassaemia intermedia patients (s°/s°) with high levels of HbF, 21 s-thalassemia major patients and 40 normal Iranian individuals were analyzed by single-strand conformation polymorphism (SSCP) and polymerase chain reaction (PCR) sequencing. Results: Two nucleotide variations in 3' HS111 (-21A>G) and 3`HS1 (179C>T) were identified. The most frequent sequence variation was 3' HS111 (-21A) in the intermedia patients and 3`HS111 (-21G) in the major thalassemia patients. In contrast to the 3`HS1 marker, both 3'HS111 A and G variants showed a correlation with each studied group. Conclusion: The HS111 marker in conjunction with other parameters could be used as appropriate genetic markers to discriminate β-thalassemia intermedia patients (β /β ) with high levels of HbF from β-thalassemia major patients.
ROLE OF PROTEIN KINASE C-α IN LEUKOTRIENE D4 - MEDIATED STIMULATION OF CYTOSOLIC PHOSPHOLIPASE A 2 IN PULMONARY SMOOTH MUSCLE CELLS

We investigated the mechanism by which LTD 4 stimulates PLA2 activity and the role of protein kinase C (PKC) in this scenario. Treatment of bovine pulmonary artery smooth muscle cells with LTD4 stimulated an aprotinin-sensitive protease activity, PKC activity, and PLA2 activity in the cell membrane. Pretreatment with vitamin E, dithiothreitol, aprotinin (serine protease inhibitor), BAPTA- AM (intracellular Ca 2+ chelator), Go6976 (PKC-α inhibitor) and AACOCF3 (cPLA2 inhibitor) prevented LTD4 stimulated PLA2 activity. Immunoblot studies of the cell membrane isolated from LTD4 stimulated cells with cPLA2 antibody elicited a marked increase in the immunoreactive protein profile. Immunoblot study with PKC-α antibody showed an additional 47-kDa immunoreactive band and that was prevented upon pretreatment of the cells with aprotinin. These results suggest that LTD4 caused an increase in reactive oxidants species (ROS), which subsequently stimulated an aprotinin sensitive protease activity and that proteolytically activated PKC-α and consequently stimulated cPLA2 activity in the cell membrane.
Whirlwind Classification with Imbalanced Upper Air Data Handling using SMOTE Algorithm and SVM Classifier

Whirlwind is a natural disaster that often occurs and is difficult to predict from some time before. Early identification is needed to prevent a lot of casualties and losses. Whirlwind caused by instability in the atmosphere. Instability in the atmosphere usually occurs at the beginning of the day and the whirlwind can be identified based on the upper air parameter which can represent atmospheric instability. The purpose of this research is to optimize SVM classification with SMOTE algorithm to handling problems in imbalanced data and this research can minimize casualties and losses or also be a breakthrough for disaster-prone areas to be given early warning. The process for identifying whirlwind has several stages, namely pre-processing, imbalanced data handling, and classification. Pre-processing is normalized data. Whirlwind data has a classification problem, namely inter-class data that is not balanced so it needs to be corrected using the SMOTE Algorithm. Research on the identification of whirlwind using a combination of SMOTE-SVM produces the best accuracy is 98.8 %. When compared to data without the SMOTE algorithm the results obtained are better if the SMOTE method is applied. The specificity value is also better when given the SMOTE method. Based on these results it can be concluded that SMOTE can overcome the problem of imbalanced data in the upper air data by increasing the value of the classification of the whirlwind.
The Development and Application of Genetic Markers for Giant Freshwater Prawns Macrobrachium Rosenbergii by Microsatellites

This article reports the development of microsatellite primers for giant freshwater prawns (Macrobrachium rosenbergii), using the genome library for this type of prawns and biotinylated probe in isolating six types of DNA fragments with base sequence repeats, namely (AG)10, (TG)10, (CAA)10, (CAG)10, (GAT)10 and (TAC)10. Four clones harboring microsatellites were chosen, namely SH2-9F, SH2-10C, SH2-11D and SH3-11G. Base sequencing found no microsatellite sequences. Four pairs of primers were designed, namely DTLSH 7, DTLSH 8, DTLSH 9 and DTLSH 12, respectively. These primers were tested on the DNA of giant freshwater prawns, and DNA band sizes were found to be 131, 174, 210 and 193 per 205 bp, respectively. The developed microsatellite primers may be used in conjunction with primers for other types of prawns. Genetic diversity checking of giant freshwater prawns in Thailand showed that their population in Thailand may be classified into two groups: one with the closest genetic relationship being those from Khon Kaen, Samut Songkhram and Ang Thong provinces while the other with similar genetic characteristics were those from these three provinces as compared to those from Surat Thani province.
Growth capacity of thermotolerant campylobacters in culture media supplemented with pig and cow blood.

In this work 60 thermotolerant Campylobacter strains (37 C. jejuni and 23 C. coli) isolated from the cows, pigs, chickens and ducks (15 strains of each type of animal) were used to establish their growth capacity on media containing cow or swine blood as potential substitutes of sheep or horse blood. The growth capacity was assessed by viable counts on cow and swine blood media, using the modified Miles and Misra method. Campylobacter strains showed better growth in the media supplemented with pig or sheep blood than with cow blood. Thus, the use of pig blood could be a supplement for Campylobacter culture medium, when there was no availability of sheep or horse blood.
CORRELATED GROWTH AND SURVIVAL OF JUVENILE SPECTACLED EIDERS: EVIDENCE OF HABITAT LIMITATION?

Abstract ABSTRACT We studied the growth andsurvival of Spectacled Eider (Somateriafischeri) ducklings to30 days of age along the lower KashunukRiver on the Yukon-Kuskokwim Delta from 1995 to2000. We replicated this study at a second site,Kigigak Island, in 1999 and 2000. Age-adjustedestimates of duckling mass and survival at30 days posthatching were highly variable.Duckling survival was consistently higher onKigigak Island in 1999 and 2000, averaging67%, while survival on the Kashunuk Riveraveraged 45% during the same time period.Duckling survival was negatively related tohatching date. At the Kashunuk River site our datasupported models that indicated age-adjusted massvaried with habitat type and declined with hatchingdate. Ducklings from Kashunuk River were heavier in1999, while ducklings from Kigigak Island wereheavier in 2000. However, we found a positivecorrelation between 30-day duckling survival andage-adjusted mass, suggesting a localizedenvironmental effect on both parameters. Weconclude that predation may be the proximatemechanism of mortality, but habitat conditions arelikely the ultimate factors influencing ducklingsurvival. Geographic variation in rates of ducklingsurvival and apparent growth suggest that spatialheterogeneity in population vital rates isoccurring at multiple levels.
Analysis of Efficiency of Overhead Irrigation in Container Production

Volume of water captured in a container as a function of sprinkler type, spacing, plant type, and container size was measured for marketable-sized plants. Percent water captured was calculated and a model to predict this value derived. Percent water captured was inversely related to the leaf area contained in the cylinder over the container when containers were separated, and with total plant leaf area at a pot-to-pot spacing. This relationship was independent of leaf curvature (concave vs. convex). Canopy densities were less related to percent water captured than leaf areas. Irrigation application efficiencies separated by spacing ranged from 37% at a close spacing to 25% at a spacing of 7.6 cm between containers. Container spacing, canopy shedding, and possibly some canopy retention of water later lost by evaporation were determined to be the main factors associated with the low efficiencies. The results suggest that higher irrigation application efficiencies would be maintained only if plants were transplanted to larger containers before reaching maximum canopy size rather than spacing existing containers to achieve more room for canopy growth. Overhead irrigation is the most practical and the most commonly used irrigation sys- tem for container production of woody or- namentals. In practice, many nursery growers use drip or microjet irrigation for material grown in containers >20 liter. Below this size, labor and material cost for the instal- lation and maintenance of an individual-type irrigation system are considered prohibitive. In Florida, the availability of water is a serious problem that is predicted to become critical around the turn of the century. With an average rainfall of ≈1000 to 1250 mm·year -1 , container nurseries apply an ad- ditional 1420 to 3040 mm of water annually to produce marketable plants (Harrison, 1976). The irrigation application efficiency (amount of water retained in the container and available to the plant/total water applied) of overhead irrigation is, at best, near 80% and drops rapidly with increased spacing be- tween pots (Furuta, 1976). Weatherspoon and Harrell (1980) reported that irrigation appli- cation efficiencies of impact sprinklers av- eraged 26% over the course of a year, and were reduced to 13% using a spinner-type sprinkler. Our objective was to determine the factors that result in these low application efficiencies for overhead irrigation. The re- sults are discussed on the basis of sprinkler type as a function of container spacing, pot size, and canopy characteristics. Three landscape plant types were used in this experiment: Rhododendron spp. 'Duc du
Harvesting as an Alternative to Burning for Managing Spinifex Grasslands in Australia

Sustainable harvesting of grasslands can buffer large scale wildfires and the harvested biomass can be used for various products. Spinifex (Triodia spp.) grasslands cover ≈30% of the Australian continent and form the dominant vegetation in the driest regions. Harvesting near settlements is being considered as a means to reduce the occurrence and intensity of wildfires and to source biomaterials for sustainable desert living. However, it is unknown if harvesting spinifex grasslands can be done sustainably without loss of biodiversity and ecosystem function. We examined the trajectory of plant regeneration of burned and harvested spinifex grassland, floristic diversity, nutrient concentrations in soil and plants, and seed germination in controlled ex situ conditions. After two to three years of burning or harvesting in dry or wet seasons, species richness, diversity, and concentrations of most nutrients in soil and leaves of regenerating spinifex plants were overall similar in burned and harvested plots. Germination tests showed that 20% of species require fire-related cues to trigger germination, indicating that fire is essential for the regeneration of some species. Further experimentation should evaluate these findings and explore if harvesting and intervention, such as sowing of fire-cued seeds, allow sustainable, localised harvesting of spinifex grasslands.
Heartworm (Paronchocerca ciconarum) Infection in 2 Saddle-Billed Storks (Ephippiorhynchus senegalensis)

Abstract Infections with filarial nematodes are well documented in numerous orders of birds worldwide. The filarial nematode Paronchocerca ciconarum has been found within the heart and pulmonary vessels of saddle-billed storks (Ephippiorhynchus senegalensis), as well as other species of African storks. Until now, identification of microfilariae on direct smears of circulating blood has been the only antemortem method reported to successfully diagnose cardiovascular filarial infections in birds. We report the use of a commercial test kit for canine heartworm (Dirofilaria immitis) antigen to aid in detecting adult P ciconarum infection in 2 saddle-billed storks, 1 at necropsy and 1 antemortem. Results of this test were positive for both birds. Direct blood smears and blood filtration tests were also used to identify circulating microfilariae. Both birds died because of separate, unrelated causes but had adult P ciconarum filariae in the pulmonary arteries and, in 1 stork, the right ventricle. On the basis of our findings in these 2 storks, testing for canine heartworm antigen, in conjunction with a blood filtration test and stained blood smear of peripheral blood, may improve detection of cardiovascular filarial infections in birds.
Temperature independence of the heat capacity of liquid water at atmospheric pressure

Debye temperature and Frenkel temperature of liquid water at atmospheric pressure are estimated from the modified phonon-polariton model. Moreover, the decrease in the Debye temperature and the increase in the Frenkel temperature as rising temperature are pointed out. The heat capacity of liquid water is given by the phonon theory reported in 2012, covering both classical to quantum regimes for both the motion of phonon polariton and the di˙usion motion of particles. Because the ratio between temperature and the Debye temperature varies from 0.8 to 1.5, leading to the temperature independence of the heat capacity of liquid water at atmospheric pressure, in agreement with experimental work.
HISTORICAL VARIETIES OF SPRING BARLEY (HORDEUM VULGARE L.) AND THEIR USE AS GENETIC RESOURCES OF MALTING QUALITY HISTORICKÉ ODRŮDY JEČMENE JARNÍHO (HORDEUM VULGARE L.) A JEJICH VYUITÍ JAKO GENETICKÝCH ZDROJŮ SLADOVNICKÉ KVALITY

Ing. Vratislav Psota, CSc. , Research Institute of Brewing and Malting, 614 00 Brno, Mostecka 7, Czech Republic. E-mail: psota@brno.beerresearch. cz Ing. Jana Bradova, Crop Research Institute, 161 06 Praha 6 – Ruzyně, Drnovska 507, Czech Republic. E-mail: bradova@vurv.cz Genetic markers of prolamin proteins – hordeins were used for the evaluation of genetic resources of old barley varieties. In the studied set, newer varieties of spring barley had markedly lower hordein polymorphism than the older ones. The selected set of varieties reflects the breeding progress of the malting quality of spring barley, first of all starch modification and proteolytic modification. Amylolytic modification of the historical varieties corresponds to the current requirements. An acceptable level of cytolytic modification was observed only in the varieties Slovenský 802 and Celechovický Hanacký; the other studied varieties exhibited weak activity of cytolytic enzymes. The variety Rubin had the best wort quality with respect to current requirements. The historical varieties or hordein lines detected in them can be used as donors of significant agronomic and qualitative traits of barley for the construction of new variet ies in the breeding process.
Impact of terminal heat stress on pollen viability and yield attributes of rice (Oryza sativa L.)

Global warming is rising as a serious concern affecting agricultural production worldwide. Rice is a staple food crop and the threshold temperature for its pollination is 35 °C. A rise in temperature above this value can cause pollen sterility and may severely affect fertilization. Therefore, a study emphasizing the rise in temperature with respect to pollen viability was conducted with eleven rice genotypes during kharif seasons of 2010 and 2011 in indigenous field conditions. Increasing mean temperature by 12 °C at full flowering was found to severely affect the spikelet attributes of the crop. All genotypes showed spikelet sterility above 90% during both seasons. The study indicated that increased temperature may limit rice yield by affecting spikelet fertility and grain filling. The net reduction in grain yield was 30.4% and 27.6% in 2010 and 2011, respectively. A clear reduction in pollen size under high temperature was shown by scanning electron microscopy.
