Authors: Pusic Ivan , Djuricic Bosiljka , Lazic Sava , Dosen Radosla , Prodanov Jasna
Published: October 2011

Aujeszky?s disease (Morbus Aujeszky) is an acute viral contagious disease occurring in a large number of domestic and wild animals. This epizootiological disease has been present in our country for quite some time now, and it has been increasingly frequently diagnosed in carnivora in the recent years. The objective of the investigations was to determine and establish the pathways for the transfer and the manner of spreading of the MA virus to carnivora. Epizootiological data on the appearance of MA, collected in the field, as well as an epizootiological report by the Serbian Ministry of Agriculture and of the Federal Ministry for Agriculture were used as material. Detailed epizootiological, clinical, pathomorphological, and laboratory analyses were performed in five critical spots for MA registered in the territory of Vojvodina province. We established the following pathways for the spread of the MA viral infection to carnivora: the consumption of thermally unprocessed swine carcasses, the consumption of thermally unprocessed pork originating from butcher shops or from regular slaughter on private farms, the consumption of viscera from emergency slaughtered sheep, cohabitation and contact with infected swine, and vaccination using a live vaccine contaminated with the MA virus.

Authors: Chaprazov Tsvetan , Borissov Ivan , Slavov Evgeni , Dzhelebov Petco
Published: October 2011

Staphylococcus aureus is the leading pathogenic cause of nosocomial infections, especially in bacteriaemia and sepsis. Phagocytosis is known to be an essential factor of innate immunity. The aim of this study was to evaluate phagocytic activity of leucocytes in experimental bacteriaemia. Bacteriaemia was induced in six adult male mongrel dogs (experimental group) by intravenous injection of Staphylococcus aureus isolate (1.2x109 cells/ml). Phagocytic activity was evaluated before infection (0 h.), and on the 2nd, 6th, 24th, 48th hour, and on the 7th, 14th and 21st day after infection. Six control animals were tested in the same dynamics. Phagocytic activity was evaluated by using the Nitrotetrazolium blue reduction (NBT) test, and the immune fluorescence method (Samnaliev et al., 1995) for detection of phagocytic index and percentage of phagocyting leucocytes (FITC marked Staphylococcus aureus were used). Percentage of phagocyting leucocytes showed an increase in experimental animals, compared to control animals, on the 24th h. Production of reactive oxygen species, evaluated by NBT, showed changes within experimental group as follows: an increase on the 24th h. compared to the 2nd h., 6th h., and the 14th day after infection; and an increase on 48th h., compared to the 2nd h. and 14th day. Comparison of reactive oxygen species production between groups, revealed an increase in the experimental group, as compared to the control group, on the 24th h. and on the 48th h. In conclusion cell elements of innate immunity are mostly activated on the first two days after inducing Staphylococcus aureus bacteriaemia in dogs.
Immunoglobulin concentration in blood serum of postcolostral calves: Ratio between immunoglobulin level and appearance of enzootic pneumonia
Authors: Jonic Branko
Published: October 2011

The timely supply of newborn calves with optimal quantities of colostrum has a key role in the process of immune protection in the early phase of their lives. Passively acquired antibodies can protect the digestive organs from infection caused by E.coli bacteria, and it seems also from the appearance of diseases of the respiratory tract. These examinations were performed on a cattle farm where bronchopneumonia was one of the most significant health problems, and a group of 39 calves were selected for the investigations. The calves were fed with their mothers? colostrum after birth, and then with collective milk. Immunoglobulin concentration was determined in blood samples taken during the postcolostral period, with the method using zinc-sulphate. At the age of 40 days, the calves were administered a polyvalent inactivated vaccine, and revaccinated 20 days after that (Vibak, Veterinary Department Subotica). In 74.34% calves, the immunoglobulin G concentration ranged from 26 to 40 g/l. In 25.66% calves, the immunoglobulin concentration was lower, from 8 to 25 g/l. The calves found to have a lower concentration of immunoglobulin in blood contracted bronchopneumonia more frequently, and the outcome of the disease in some cases was mortality, even.
Efficacy of mineral and organic adsorbent in alleviating harmful effects of zearalenone on pig blood serum protein status
Authors: Nesic Ksenija , Stevanovic Jelka , Sinovec Zlatan
Published: October 2011

The influence of zearalenone on blood serum protein status and the feasibility of utilizing a modified clinoptilolite and esterified glucomannan to alleviate its harmful effects was examined in two trials, 31 and 29 days long, conducted on a total of 64 pigs (32 each) 60 days old, divided into four groups, each containing 8 pigs. Control groups (K) received noncontaminated feed, while experimental groups received feed supplemented with 3.84 mg/kg in the first trial and 5.12 mg/kg of zearalenone in the second trial. Pigs in the first experimental groups (O-I) were given feed with toxin only. Modified clinoptilolite in the amount of 0.2% and esterified glucomannan in the amount of 0.1% were introduced in contaminated feed of the second (O-II) and the third experimental groups (O-III) of both trials. With the use of contaminated feed, a declining trend of the A/G ratio was observed: decrease of albumin content and increase of globulin content on account of the _ globulin fraction. A decrease of the _ globulin fraction was detected at the same time. Total protein concentration was also lower. The application of adsorbents successfully alleviated harmful effects of the F-2 toxin on the affected biochemical parameters in blood serum.

Published: October 2011

Examinations were carried out during the period from January 2006 until March 2007 on a total of 449 samples of the cecum of broilers and the cecum and the colon of pigs. These samples included 251 samples originating from broilers and 198 samples of pig cecums and colons. All the listed samples were obtained by scraping the surface of these parts of the digestive system of broilers and pigs. At the site of sampling, the diluted material was sown on a medium (Karmali agar), in order to get individual colonies. After sowing, the bases were placed in anaerobic jars in which microaerophilic conditions were achieved using Campy Pak, BBL bags. On arrival at the laboratory, the jars containing the sown bases were placed in a thermostat, at a temperature of 42oC for 48 hours for the purpose of incubation. Following incubation, the grown colonies were examined macroscopically, and then microscopic preparations were made from them, which were stained with 2% carbol fuchsin after drying and fixation. Those isolates which were in the form of a comma, the letter S, or gull's wings in the microscopic preparations were considered Campylobacter species (Figures 1 and 2). The isolated thermophilic campylobacteria were identified using conventional and commercial biochemical tests API Campy, manufactured by Bio M?rieux, France. With the application of these microbiological methods, thermophilic Campylobacter species were isolated from 203 (80.88%) of the 251 samples of broiler cecums. Furthermore, thermophilic campylobacteria were isolated from 153 (77.27%) of the 198 samples from the cecum and colon of pigs taken within these investigations. The obtained results indicate that there is a somewhat greater prevalence of these bacteria among the broilers. However, such a high percentage of both broilers and pigs colonized by thermophilic Campylobacter species could pose a serious problem, in particular when it is known that infections of humans caused by the consumption of insufficiently thermally processed meat of broilers or pigs are not infrequent.
Animal welfare assessment
Authors: Vucinic Marijana , Lazic Ivana
Published: October 2011

The paper deals with animal welfare definitions and animal welfare assessment. Animal welfare is a prolonged mental state, resulting from how the animal experiences its environment over time. There are different methods for animal welfare assessment. The four basic criteria for animal welfare assessment are feeding, housing, health and appropriate behavior. Therefore, criteria used to assess animal welfare are not direct measures of the mental state but only parameters that need to be interpreted in terms of welfare. The immediate housing environment and feeding may influence animal welfare either positively, when most of the important requirements are respected, or negatively, when animals are exposed to various stress factors and unpleasant emotions that contribute to animal disease, injuries or inappropriate behavior. Therefore, animal welfare is a unique link between housing conditions, feeding and watering on one side, and animal health status and behavior on the other side.

Published: October 2011

Objective of this research was to present and compare results of the research of the effect of two fattening methods, on deep litter and conventional method (without litter). Slaughter properties have been determined with special focus on distribution of certain tissues in pig carcasses fattened in two different ways. Research was carried out on meat, fattening pig breeds - Swedish landrace. Research included 115 fatteners from single farm in Vojvodina. Depending on the housing conditions, two groups were formed: first group - group I (60 heads in group) was housed on deep litter, and the second - group II (55 heads in group), without litter. At the end of the trial, pigs were slaughtered and dissection was performed on cooled (+4?C) left carcass sides and meat yield determined using the method of partial dissection (Walstra and Merkus, 1996). Carcass sides were cut in 12 parts. Based on the meat quantity in four main carcass parts: leg, shoulder, back-loin part (BLP) and belly-rib part (BRP), which contain 75% of total musculature mass and mass of tenderloin of carcass side, meat percentage in carcass sides was calculated according to formulation (Manojlovic Danica et al., 1999). Fatteners housed on deep litter had statistically significantly (**p<0.01) lower mass of cool carcass sides (38.38 kg) compared to fatteners housed without litter (40.90 kg). Higher absolute and relative shares of leg (10.22 kg and 25.02%) were established and higher absolute yield of shoulder (5.35 kg ) in fatteners housed in boxes without litter (II group). Yield of muscle tissue in leg, shoulder, BLP and BRP was higher in fatteners of the II group (without litter) compared to pigs fattened on deep litter, and also statistically highly significant differences were established in share of muscle tissue in shoulder (**p<0.01) and considerable differences in regard to share of muscle tissue in BRP (*p<0.05). Meat yield of pig carcass sides was determined by method of partial dissection, for fatteners housed on deep litter it was 47,92%, and in case of fatteners housed without litter it was 53.89%. Established differences were very significant (**p<0.01).

Published: October 2011

In order to broaden the range of diagnostic methods for determining stomach diseases and to make these methods a greater part of the daily clinical practice, the procedures of radiological, ultrasound and endoscopic examinations should be worked out in more detail, their limits and possibilities should be established, the topographic-anatomical and morphological status of the stomach should be described in a radiological, ultrasound and endoscopic picture, and the most represented stomach diseases should be defined as well. The paper presents the results of six-month investigations of stomach diseases in dogs of different breeds and ages. A total of 20 animals were examined: seven German Shepherds, four golden retrievers, three rottweilers, two dobermans, two big schauzers, and two mixed-breed dogs. Cases of acute gastritis, chronic ulcerous gastritis, foreign body cases, and stomach tumors have been described.

Published: October 2011

Pyometra (chronic purulent inflammation of the uterus) is a frequent reproductive disorder in sexually mature bitches that usually occurs between the 4th week and the 4th month following estrus when the animal is not pregnant. The objective of this investigation was to examine the influence of the breed of bitch on the age when pyometra is diagnozed, and in the territory of the Autonomous Province of Vojvodina. The average age of 321 examined bitches with diagnozed pyometra was 8.4 years. A statistically significant (P?0.05) difference was established in the average age of bitches of big breeds (7.3 years) in comparison with the age of bitches of small breeds, at the time of pyometra occurrence (9.8 years). Bitches of mixed breeds were aged 8.8 years on the average when they were diagnozed with pyometra. Pyometra was diagnozed at the age between 7 and 9 years in 52% of the examined bitches of big breeds, while 51% bitches of small breeds were diagnozed with pyometra when they were considerably older (?10 years). On the grounds of the results of these investigations, it can be concluded that the risk of pyometra occurring increases significantly after 5 years of age, but that breed has a significant effect on the age at which pyometra occurs in bitches.

Published: October 2011

In this study, we have successfully demonstrated the fabrication of a biosensor based on well aligned single-crystal zinc oxide (ZnO) nanorods which were grown on gold coated glass substrate using a low temperature aqueous chemical growth (ACG) method. The ZnO nanorods were immobilized with penicillinase enzyme using the physical adsorption approach in combination with N-5-azido-2-nitrobenzoyloxysuccinimide (ANB-NOS) as cross linking molecules. The potentiometric response of the sensor configuration revealed good linearity over a large logarithmic concentration range from 100 µM to 100 mM. During the investigations, the proposed sensor showed a good stability with high sensitivity of ~121 mV/decade for sensing of penicillin. A quick electrochemical response of less than 5 s with a good selectivity, repeatability, reproducibility and a negligible response to common interferents such as Na1+, K1+, d-glucose, l-glucose, ascorbic acid, uric acid, urea, sucrose, lactose, glycine, penicilloic acid and cephalosporins, was observed.
THE DEVELOPMENT OF THE QUALITY MANAGEMENT SYSTEM IN TERMS OF KNOWLEDGE MANAGEMENT / KOKYBĖS VADYBOS SISTEMŲ TOBULINIMAS ŽINIŲ VADYBOS ASPEKTU
Authors: Vitkauskas Romualdas
Published: October 2011

The interaction of quality management and knowledge man­agement are analyzed quite widely in scientific literature and discussed with reference to various models integrating these two management theories. However, there are not enough precise tools that could provide a possibility of improving the quality of products and services through knowledge management. To this end, the article examines the already existing models for the interaction between quality management and knowledge management. The results of a survey on Lithuanian industry show what organizational knowledge is the most important while implementing quality management principles aimed at improving quality. The correlation analysis method showed the relationship between quality management principles (process approach, continual improvement, management, facts) and the factors defining the product and process quality (the extent of determining process execution time, process resources, costs of process stages, indicators for products and/or services, the dura­tion of the process, the extent of measuring indicators, the extent of collecting information on indicators, the extent of collecting information about the costs of the process).

Les femmes qui accouchent sous le secret en France, 2007-2009
Authors: Villeneuve-Gokalp Catherine
Published: October 2011

Résumé Chaque année en France, 600 à 700?femmes demandent le secret de leur accouchement. Cette étude, réalisée dans 83 des 100?départements, a permis de rassembler des informations administratives sur 835?accouchements secrets ayant eu lieu de juillet 2007 à juin 2009, et de connaître les caractéristiques sociodémographiques ainsi que le contexte de la grossesse de 739?femmes. À la naissance, 10?% des femmes établissent la filiation, 13?% indiquent leur identité dans le dossier de l’enfant et 29?% y laissent un pli fermé qui, si plusieurs conditions sont remplies, permettra à l’enfant de connaître son identité. Trois «?profils?» principaux de femmes ont été définis : les «?jeunes femmes dépendantes de leurs parents?» (25?% des femmes), les «?femmes indépendantes?» (25?%), et les «?femmes seules en situation de précarité?» (15?%). L’accouchement secret n’est donc pas seulement le fait de très jeunes femmes «?abandonnées?» par leur partenaire ou en situation de précarité, même si elles sont effectivement surreprésentées. Dans le délai légal de deux mois après la naissance, 14?% des mères reprennent l’enfant. Les femmes qui reviennent le plus souvent sur leur décision sont celles qui ont dû se séparer de l’enfant sous la pression de contraintes familiales ou économiques. L’accouchement secret étant plus rare chez les femmes qui ont acquis leur indépendance économique ou qui vivent en couple, celles qui y ont recours seraient plus déterminées et se rétracteraient moins souvent.
Migration internationale et conditions d'habitat des ménages à Dakar
Authors: Lessault David , Beauchemin Cris , Sakho Papa
Published: October 2011

Résumé Le secteur immobilier est considéré au Sénégal comme le principal débouché des investissements des Sénégalais de l’extérieur. Ainsi, la manne que représentent les transferts des migrants pourrait bien être un facteur d’amélioration des conditions d’habitat des ménages dakarois. C’est l’hypothèse que teste cet article à travers diverses analyses réalisées à partir des données collectées à Dakar dans le cadre de l’enquête Mafe. Sans surprise, les premiers résultats montrent qu’au moment de l’enquête, les ménages avec migrant(s) sont globalement mieux logés que les ménages sans migrant (type de logement, densité, niveau d’équipement). Mais la suite des résultats nuancent l’effet de la migration internationale sur les conditions d’habitat des ménages dakarois. D’une part, l’argent de la migration perçu par les ménages est faiblement utilisé à des fins de construction ou de transformation de l’habitat. D’autre part, l’analyse des conditions d’accès à la propriété des ménages, au moment de l’entrée dans le logement et non à celui de l’enquête, montre l’absence d’influence des migrants. Finalement, les investissements immobiliers des migrants semblent assez peu orientés vers l’amélioration des conditions d’habitat des ménages auxquels ils sont apparentés. Ceci n’empêche pas qu’ils puissent jouer un rôle dans la transformation de l’habitat à Dakar, notamment à travers des investissements locatifs.
Quand l'humour contribue à la performance de la relation
Authors: Barth Isabelle
Published: October 2011

Résumé Les situations où l’humour est mobilisé en entreprises sont très nombreuses : on observe qu’elles sont souvent liées (mais sans obligation) à des moments de tensions et visent à les dénouer : tensions entre individus (situations de conflits), tensions situationnelles (problèmes liés au contexte de travail). Nous faisons l’hypothèse dans cette recherche que l’humour peut contribuer à la performance de la relation, de nature commerciale et/ou managériale (nous limitons notre champ aux services commerciaux). Une observation participante de plusieurs situations en entreprise nous permet de proposer une retranscription et une analyse de ce processus très complexe : double processus à la fois cognitif et affectif qui se met en place entre les partenaires de l’interaction. La littérature mobilisée est empruntée à la linguistique, la sociologie, la psychologie et la littérature car les sciences de gestion se sont encore peu intéressées à ce sujet, qui nous semble pourtant riche de potentiel explicatif et argumentatif dans le champ de la relation. La méthodologie mobilisée est l’approche énonciative issue de la socio-linguistique.

L'être-sujet
Authors: Leymarie Stéphane , Muller Renaud
Published: October 2011

Résumé Quelle place reconnaît-on au sujet dans la conception des organisations ? On pourrait penser que l’introduction des sciences humaines dans les sciences de gestion ait été l’occasion de le faire. Il convient bien naturellement de s’interroger sur les exigences que suppose la considération de l’individu en tant que sujet dans un contexte organisationnel. Nous prendrons appui sur le travail de la notion de sujet chez Lacan, au carrefour de la tradition philosophique et de son expérience clinique. Cet examen de notion nous amènera à considérer le sujet comme la posture de l’individu qui accède à une représentation de soi au travers de son environnement, et qui, en même temps a besoin de s’en différencier. Le sujet peut ainsi être considéré comme une posture interstitielle entre l’individu et son organisation qui contribue autant à lui donner une image qu’il doit s’en détacher pour exister en propre. Forts de cette définition, nous examinerons comment les conceptions de l’organisation, au regard de la classification théorique en métaphores proposées par Morgan, ménagent un espace à cette posture. Nous constatons l’apport des sciences humaines dans les théories des organisations et du management pour reconnaître le rôle structurant de l’identité. Nous soulignerons toutefois les carences majeures dans la prise en compte des besoins de différenciation entre l’individu et son organisation, le besoin d’une prise de distance avec le miroir organisationnel, l’identité professionnelle. Cette nécessité est à mettre en rapport avec le développement de risques psychosociaux qui témoignent de ce besoin de distanciation.
Comprendre les femmes au foyer, des intermittentes du travail ?
Authors: Dieu Anne-Marie , Delhaye Christine , Cornet Annie
Published: October 2011

Résumé Il peut sembler étonnant de proposer un article sur les femmes au foyer un numéro spécial consacré à la GRH. En effet, les femmes au foyer ne sont a priori pas concernées par le marché du travail, elles sont d’ailleurs reprises dans les statistiques dans la catégorie des « inactives. » Pourtant, dans le cadre d’une recherche qualitative que nous avons menée pour le compte de la Région Wallonne de Belgique auprès de femmes ayant cessé pendant plus de deux ans de travailler pour des raisons familiales, nous avons pu constater que le rapport au travail et au marché de l’emploi des femmes dites « inactives » est bien plus complexe que ce que les représentations communes laissent apparaître. Les femmes au foyer développent en effet, lors de leur période de vie « au foyer », une série d’activités productives, de service et créatives, qui sortent de la simple sphère familiale et qui contribuent à leur procurer une série de gratifications sociales, psychologiques et symboliques, tout en leur assurant des revenus occasionnels ou plus réguliers. Elles développent un « rapport en pointillé » au monde du travail dont elles ne sont pas toujours conscientes elles-mêmes. Ces activités, des « impensés de la GRH » leur permettent pourtant de développer des compétences transposables sur le marché du travail mais encore trop peu prises en compte par elles-mêmes comme par les employeurs potentiels.

Multi-View Stereo Reconstruction Technique
Authors: Song Peng , Wu Xiaojun
Published: October 2011

3D modeling of complex objects is an important task of computer graphics and poses substantial difficulties to traditional synthetic modeling approaches. The multi-view stereo reconstruction technique, which tries to automatically acquire object models from multiple photographs, provides an attractive alternative. The whole reconstruction process of the multi-view stereo technique is introduced in this chapter, from camera calibration and image acquisition to various reconstruction algorithms. The shape from silhouette technique is also introduced since it provides a close shape approximation for many multi-view stereo algorithms. Various multi-view algorithms have been proposed, which can be mainly classified into four classes: 3D volumetric, surface evolution, feature extraction and expansion, and depth map based approaches. This chapter explains the underlying theory and pipeline of each class in detail and analyzes their major properties. Two published benchmarks that are used to qualitatively evaluate multi-view stereo algorithms are presented, along with the benchmark criteria and evaluation results.
Image Focus Measure Based on Energy of High Frequency Components in S-Transform
Authors: Mahmood Muhammad Tariq , Choi Tae-Sun
Published: October 2011

Focus measure computes sharpness or high frequency contents in an image. It plays an important role in many image processing and computer vision applications such as shape from focus (SFF) techniques and multi-focus image fusion algorithms. In this chapter, we discuss different focus measures in spatial as well as in the transform domains. In addition, we suggest a novel focus measure in S-transform domain, which is based on the energy of high frequency components. A localized spectrum, by using variable window size, provides a more accurate method of measuring image sharpness as compared to other focus measures proposed in spectral domains. An optimal focus measure is obtained by selecting an appropriate frequency dependent window width. The performance of the proposed focus measure is compared with those of existing focus measures in terms of three dimensional shape recovery and all-in-focus image generation. Experimental results demonstrate the effectiveness of the proposed focus measure.
Modular Stereo Vision
Authors: Oon-Ee Ng , Ganapathy Velappa , Ponnambalam S.G.
Published: October 2011

The two-frame stereo vision algorithm is typically conceived of and implemented as a single process. The standard practice is to categorize individual algorithms according to the ‘type’ of process used. Evaluation is done based on the quality of the depth map produced. In this chapter, we demonstrate that the stereo vision process is actually composed of a number of inter-linked processes. Stereo vision is shown to be modular in nature; algorithms implementing it typically implement distinct stages of the entire process. The modularity of stereo vision implies that the specific methods used in different algorithms can be combined to produce new algorithms. We present a model describing stereo vision in a modular manner. We also provide examples of the stereo vision process being implemented in a modular manner, with practical example code. The purpose of this chapter is to present this model and implementation for the use of researchers in the field of computational stereo vision.
Stereo Vision Depth Estimation Methods for Robotic Applications
Authors: Nalpantidis Lazaros , Gasteratos Antonios
Published: October 2011

Vision is undoubtedly the most important sense for humans. Apart from many other low and higher level perception tasks, stereo vision has been proven to provide remarkable results when it comes to depth estimation. As a result, stereo vision is a rather popular and prosperous subject among the computer and machine vision research community. Moreover, the evolution of robotics and the demand for vision-based autonomous behaviors has posed new challenges that need to be tackled. Autonomous operation of robots in real working environments, given limited resources requires effective stereo vision algorithms. This chapter presents suitable depth estimation methods based on stereo vision and discusses potential robotic applications.

Authors: Zhu Yu Ying , Li Qiang , He Yun Hua , Wang Ge , Wang Xing Hua
Published: October 2011

The Ti50Fe22Ni22Sn6 amorphous powder was prepared by mechanical alloying with a high-energy planetary ball mill. Crystallization kinetics of the milled amorphous powders was investigated by DSC. Thermal analysis showed that when the heating rate increasing from 10K/min to 40K/min, the super-cooled liquid region of milled amorphous alloy increased from 93K to 110K. On the basis of the obtained DSC curves, the characteristic temperatures of the amorphous powders could be measured. The equations of Kissinger and Ozawa were used to calculate the crystallization activation energies of the milled amorphous alloy for comparing. The activation energy for the glass transition Eg had the maximum values of 650KJ/mol and 629KJ/mol calculated from Kissinger and Ozawa, respectively. In addition, the second crystallization process had a higher activation energy value comparing with the others crystallization events.

In the course of a search for chemotherapeutic agents inhibiting suspected peridontitis bacteria, extracted and purified substances from lotus leaf were identified by antimicrobial and Anti-inflammation activity tests with use of the broth micro-dilution methods on 96-microwell plate and ELISA assay. The antimicrobial activity of extracts was tested against four microorganisms, namely: Streptococcus mutans , Porphyromonas gingivalis, Actinobacillus actinomycetemcomitans and Candida albicans. The Anti-inflammation activity of extracts was tested for inhibition of inflammatory cytokines IL-8 and IL-6 in macrophage BF24. And one pure component was subjected to spectroscopic analysis using UV, IR, EMI-MS, EIMS, 1H-NMR, 13C-NMR, 1H-COSY and HMQC. Our data showed that the minimum inhibitory concentrations of the pour component was less than 5mg/ml for all four microorganisms and the minimum concentration with anti-inflammation was 0.2mg/ml for both IL-8 and IL-6. The component was determined to be Lysicamine. Thus, we conclude that Lysicamine extracted from lotus leaves may be a potential antibacterial and Anti-inflammation agent for oral infection .

Chlortetracycline (CTC), antimicrobial chemical, is widely used to treat disease and protect the health of animals. As CTC is poorly absorbed during digestion, the majority of the bioactive compound or metabolites are excreted in faeces and urine. Toxicogenomics approach was used to examine the toxicological effects of CTC on earthworms (E. fetida). Quantification of gene expression levels encoding antioxidative system and biotransformation enzymes were analyzed in E. fetida. The results showed that GST transcript level was significantly inhibited at 300 mg CTC kg-1, with an approximately a 65% decrease compared to the control. Ferritin and serine were marked by high level transcripts at the lowest concentration and followed by decreasing levels with the increased concentraion. Hsp70 transcript appeared to be disrupted at the lowest concentration. Thus, environmental assessment using these genes expression levels in earthworms might be sensitive and helpful in the early diagnosis of potentially polluted soil.

.Adult Tessaratoma papillosa (Drury) (Hemiptera: Pentatomidae) secreted volatiles from metathoracic glands (MTG). Behavior and olfactory responses of adult bugs to their MTG secretions were tested using a Y-tube olfactometer and an electroantennogram (EAG). The results indicated that males were obviously attracted by female secretions and repelled by male secretions. Secretions of adult males elicited the greatest response of male antennae, whereas the lower response of male antennae to MTG secretions of adult females was recorded. The four compounds, (E)-2-octenal, undecane, dodecane and tridecane were tested for the EAG activity and behavior response with male adults at different concentrations. In EAG assays, the antenna of male T. papillosa showed the highest sensitivity to (E)-2-octenal (10 μL /μL) and the second highest sensitivity to undecane (10 μL /μL), but a similar sensitivity to other stimuli. Unlike EAG results, males were attractive to (E)-2-octenal (10-2 and 10-1 μL /μL) and tridecane (10 μL /μL), and repelled by (E)-2-octenal (10-3, 1, 10 and 102 μL /μL) and tridecane (10-1 μL /μL) in the Y-tube olfactometer. Our data suggested that (E)-2-octenal and tridecane may be part of a complex pheromone system in T. papillosa.

Natural gas of Tazhong-1 gas field contains 7.7% carbon dioxide and 2.31% hydrogen sulfide, and produced water salinity is up to 140000mg/L,the well-bore tube has seriously potential corrosion destructive with natural gas being exploited. Based on the corrosion type partition of down-hole tube for eighteen production wells of Tazhong-1 gas field, P110,P110S and P110SS corrosion behavior were investigated under the conditions of simulated formation water containing carbon dioxide or hydrogen sulfide/carbon dioxide, and corrosion inhibitors were chosen to meet need of anticorrosion of Tazhong-1 gas field. The results show that fifteen wells in eighteen production wells belong to hydrogen sulfide corrosion of both hydrogen sulfide and carbon dioxide influence. Other wells are singular carbon dioxide corrosion. The most severe corrosion of three types of down-hole tubes all occurs at 90°C in both corrosion media, and their corrosion resistance order is respectively P110>P110S>P110SS and P110S>P110SS>P110 under the conditions of simulated formation water containing carbon dioxide or hydrogen sulfide and carbon dioxide. The selected anti-temperature corrosion inhibitors (YU-1、YU-4) can control the corrosion rate of three types of down-hole tubular goods within 0.076mm/a in simulated formation water media with carbon dioxide (PCO2=0.08～4.64MPa) or hydrogen sulfide and carbon dioxide (PH2S/Pco2=1.3/4.64Mpa) while added amount of the inhibitor is 120～300mg/L or 200mg/L. All of these provide technical support for safe and fast development of Tazhong-1 gas field.

Published: October 2011

A method for indirect online over-temperature detection of isolators in high voltage switchgear is proposed，which is based on Na Superionic Conductor CO2 sensor. The over-temperature detecting principle is put forward and an over-temperature detecting system based on the method is introduced. The reliability of over-temperature detection depends on signal noise ratio (SNR), but the sensor and signal processing determine the SNR of CO2 signal. Based on quantitative analysis, it is concluded that Na Superionic Conductor CO2 sensor has higher SNR. By signal processing, the necessity of moving average filter for SNR is demonstrated. A temperature compensation circuit is adopted to eliminate the influence of temperature. In view of the characteristics of rude signal, an appropriate method of real-time digital filtering is used to improve the Signal-to-Noise Ratio. The different features of the signal under over-temperature condition have been analyzed and compared to those under normal conditions. The paper introduces a reliable algorithm for identifying over-temperature detection based on sequential section differences. Experiments prove that the method is feasible.

Published: October 2011

Thermal simulation test, TEM(Transmission Electron Microscope) and nanobeam EDS techniques were used to investigate the dissolving and precipitation behavior in Nb-bearing mciroalloyed steel. The experimental results indicate that: there are two families of precipitates in the as forged samples. The larger precipitates of Nb(C,N) disappear after being held for 2h at 1300°C,while the inclusions of MnS formed from the solidification even remain for 48h held at that temperature. After 30% of predeformtion at 850°C and 900°C, the strain-induced precipitation occurs, that is, the other tiny precipitates. Compared with the samples relaxed at 850°C, the ones that are held at 900°C show larger particles by same holding time but demonstrate the same size when the relaxation time reaches 1000s.
