Mid-Infrared Spectra of Polycyclic Aromatic Hydrocarbon Emission in Herbig Ae/Be Stars

We present spectra of four Herbig Ae/Be stars obtained with the Infrared Spectrograph (IRS) on the Spitzer Space Telescope. All four of the sources show strong emission from polycyclic aromatic hydrocarbons (PAHs), with the 6.2 μm emission feature shifted to 6.3 μm and the strongest C–C skeletal-mode feature occurring at 7.9 μm instead of at 7.7 μm, as is often seen. Remarkably, none of the four stars has silicate emission. The strength of the 7.9 μm feature varies with respect to the 11.3 μm feature among the sources, indicating that we have observed PAHs with a range of ionization fractions. The ionization fraction is higher for systems with hotter and brighter central stars. Two sources, HD 34282 and HD 169142, show emission features from aliphatic hydrocarbons at 6.85 and 7.25 μm. The spectrum of HD 141569 shows a previously undetected emission feature at 12.4 μm that may be related to the 12.7 μm PAH feature. The spectrum of HD 135344, the coolest star in our sample, shows an unusual profile in the 7-9 μm region, with the peak emission to the red of 8.0 μm and no 8.6 μm PAH feature.
Microbes as Heavy Metal Removers in Industrial Waste

Environmental pollution is the greatest threat posed to the humanity and the biosphere as a whole. Among these water pollution is of great significance. Water pollution causes undesirable changes in the physico-chemical and biological properties of water ,which may be harmful to the activities of man and domestic species.Now water pollution is a global problem due to rapid increase in industrialization. The effluent from industries contain heavy metals like Cu,Pb,Zn,Hg,Cd,Mn etc. all of which are toxic to animals.The heavy metals discharged from industries into lakes and ponds reach the human through the food chain.The special characteristics of heavy metal chemicals is their strong attraction to biological system and slow elimination from it.Metal toxicity means the uptake of metals by the cell. The time required to develop tolerance mechanisms are influenced by biotic and abiotic factors.Many microorganisms acquire a mechanism that enables them to repair metal toxicity damages.
Changes in abundance of coral-reef bottom components related to mass mortality of the sea urchin Diadema antillarum

We studied the effect of a reduction in grazing pressure, following mass mortallties of the abundant sea urchin Diadema antillarum, on coral-reef bottom components at Curaqao (Netherlands Antilles). We surveyed cover of fleshy and fllamentous algae, scleractinlan corals, crustose coralline algae, loose sediment and a miscellaneous category in permanent quadrats at depths of 27, 15 and 3 m during 1 yr. At all depths, cover of fleshy and filamentous algae increased significantly, reaching a new equhbrium. Corals, crustose corallines and/or loose sediment generally decreased in cover, but not all changes were significant. At the species level, we found the coral Agar~cia agaricites, at 15 m, to be relatively vulnerable among corals. The macroalgae Lobophora variegata and Dictyota spp. increased significantly in cover at 27 and 15 m, respectively. We expect, in view of the observed continuously low rates of recrutment of D. antillarum, and in vlew of the new equilibrium in algal cover, no rapid return to the origlnal situation, unless other herbivorous organisms will take over the role of D. anWlarum.
Aging and the financing of social security in Switzerland

SummaryThe gains in life expectancy are expected to double the dependency ratio and increase population by 10% in Switzerland until 2050. To quantify the effects on social security and public finances, we use an overlapping generations model with five margins of labor supply: labor market participation, hours worked, job search, retirement, and on-the-job training. A passive fiscal strategy would be very costly. A comprehensive reform, including an increase in the retirement age to 68 years, may limit the tax increases to 4 percentage points of value added tax and reduce the decline of per capita income to less than 6%.
Local Anesthetic "Resistance" An Original Contribution

most were equally numb to all three local anesthetics (lidocaine, bupivicaine, and mepivicaine), 7.5% of the patients consistently chose mepivicaine as the local anesthetic resulting in the most hypoesthesia. For patients who had previously undergone an unsuccessful procedure with bupivicaine (the standard local anesthetic used in our practice), the same procedure with mepivicaine provided good relief. Patients are now questioned on their initial evaluation about a history of difficulty getting numb, for instance at the dentist, and preemptively skin tested prior to any invasive procedure.
Anatomy of the male reproductive system of Phrynops geoffroanus (Testudines: Chelidae) - doi: 10.4025/actascibiolsci.v33i4.8091

The reproductive system of male Phrynops geoffroanus adults is macroscopically described and the variation in testicular biometry is evaluated. A pair of oval testes is connected by the efferent ductules to the epididymis, which continue as deferent ducts, which emerge in the penis. The volume of the gonads showed the highest averages during spring and summer months. GSI varied significantly throughout the year, with the highest averages observed in the months that correspond to the end of spring and the beginning of summer, when the reproduction of the species takes place, and the lowest averages were seen in winter, suggesting a cyclical testicular activity.
Deciding how to treat anterior sectors with missing teeth

This article presents solutions to problems posed by missing teeth in the anterior sector of the arch by synthesizing three groups of parameters, those related to patients, those related to dentists, and those related to the orthodontist. But the patient, or the parents of patients who are young children, in consultation with the treatment professionals, must make the final decision.
Implications of MicroRNAs in the Vascular Homeostasis and Remodeling

Vascular remodeling or arterial remodeling is a process of adaptive alteration of vascular wall architecture and leads to the endothelial cell (EC) dysfunction and synthetic or contractile phenotypic change of VSMCs, and the infiltration of mono‐ cytes and Macrophages that promotes vascular diseases including atherosclerosis. Recent findings have demonstrated that microRNAs (miRNAs) are involved in regulating gene expression at posttranscriptional level and disease pathogenesis. A change of miRNA expression profiles plays key roles in the gene expressions and the regulation of cellular functions. In this chapter, we summarize the vascular remodel‐ ing-related miRNAs and their functions in vascular biology.
A decoupled path-following control algorithm based upon the decomposed trajectory error

This paper proposes a new path-following control algorithm for the machine tool servo systems. The controller first decomposes the normal tracking error from the advancing tangential error. A dynamic decoupling procedure is then proposed to the advancement mechanism and the trajectory tracking mechanism in the machine tool servo. A dynamic decoupling controller is propose to operate on the decomposed tangential and normal tracking errors. The normal control minimizes the perpendicular tracking error while the tangential control maintains a desired feed rate. The method is applied on an experimental X-Y table, and the results show good tracking and trajectory following characteristics. The new algorithm enables the design of a non-overshooting controller along the path. This would allow no-over-cutting process for the machine tool operation.
The Role of Anxiety in Neuropsychological Dysfunction in Early HIV Disease.

The literature on neuropsychological functioning in patients with asymptomatic HIV disease is widely discrepant with prominent researchers on either side of the debate about whether or not early HIV infection is associated with neuropsychological deficits. Many theories have been put forth to account for these varied results, including inadequate study design, lack of measures sensitive enough to detect differences, and pooling of test scores across individuals that do have deficits, but not necessarily in the same areas. The present investigation was designed to examine the role o f anxiety as a possible confounding variable that could account for differences across HIV serostatus groups. It also investigated the hypothesis that HIV seropositive and HIV seronegative patients differ in terms of their appraisals of their performance and that higher levels of anxiety are related to lowered estimation of performance. The HIV seropositive and HIV seronegative groups in this investigation did not differ in terms of their neurocognitive functioning. When the groups were further divided in terms of their anxiety level, again there were no differences in their neurocognitive functioning. The investigation therefore failed to identify anxiety as a contributor to neuropsychological dysfunction in HTV seropositive subjects, however, given the lack of HIV group differences in neurocognitive functioning, it did not rule out a potential role for anxiety either.
A 6-bit 600-MS/s 5.3-mW asynchronous ADC in 0.13-μm CMOS

An asynchronous analog-to-digital converter (ADC) based on successive approximation is used to provide a high-speed (600-MS/s) and medium-resolution (6-bit) conversion. A high input bandwidth ( 4 GHz) was achieved which allows its use in RF subsampling applications. By using asynchronous pro- cessing techniques, it avoids clocks at higher than the sample rate and speeds up a nonbinary successive approximation algorithm utilizing a series nonbinary capacitive ladder with digital radix calibration. The sample rate of 600 MS/s was achieved by time-in- terleaving two single ADCs, which were fabricated in a 0.13- m standard digital CMOS process. The ADC achieves a peak SNDR of 34 dB, while only consuming an active area of 0.12 mm and having power consumption of 5.3 mW. Index Terms—Analog-to-digital conversion, analog integrated circuits, asynchronous logic circuits, calibration, capacitive ladder, comparators, high-speed integrated circuits, impulse radio, non- binary successive approximation, ultra-wideband (UWB).
Water and sediment fluxes in Mediterranean mountainous regions: comprehensive dataset for hydro-sedimentological analyses and modelling in a mesoscale catchment (River Isábena, NE Spain)

Abstract. A comprehensive hydro-sedimentological dataset for the Isábena catchment, northeastern (NE) Spain, for the period 2010–2018 is presented to analyse water and sediment fluxes in a Mediterranean mesoscale catchment. The dataset includes rainfall data from 12 rain gauges distributed within the study area complemented by meteorological data of 12 official meteo-stations. It comprises discharge data derived from water stage measurements as well as suspended sediment concentrations (SSCs) at six gauging stations of the River Isábena and its sub-catchments. Soil spectroscopic data from 351 suspended sediment samples and 152 soil samples were collected to characterize sediment source regions and sediment properties via fingerprinting analyses. The Isábena catchment (445 km2) is located in the southern central Pyrenees ranging from 450 m to 2720 m a.s. l. ; together with a pronounced topography, this leads to distinct temperature and precipitation gradients. The River Isábena shows marked discharge variations and high sediment yields causing severe siltation problems in the downstream Barasona Reservoir. The main sediment source is badland areas located on Eocene marls that are well connected to the river network. The dataset features a comprehensive set of variables in a high spatial and temporal resolution suitable for the advanced process understanding of water and sediment fluxes, their origin and connectivity and sediment budgeting and for the evaluation and further development of hydro-sedimentological models in Mediterranean mesoscale mountainous catchments. The dataset is available at http://doi.org/10.5880/fidgeo.2018. 011.
The microbiological food safety control of meat and meat products at the State Veterinary Institute in Olomouc in 2010 – 2014

Meat and meat products are an important segment of the food chain for the majority of consumers in the Czech Republic. One of the main tasks of laboratory testing in this area is the safety of food and the raw materials used in its production. The aim is to protect the health of consumers from foodborne infections or intoxication. A considerable proportion of foodborne infections are caused by bacteria and their toxins. Therefore, activities in this area are also carried out by the State Veterinary Institute (SVI) in Olomouc. This paper presents 5-year trends in the results of analyses of meat and meat products focusing on the bacteria Salmonella spp. , Listeria monocytogenes, Staphylococcus aureus, Escherichia coli and staphylococcal enterotoxins. An overview is presented of the microbiological findings in meat and meat product samples analyzed from 2010 to 2014 at the SVI in Olomouc. Bacteria of the genus Salmonella were detected in 2.2% and non-complying findings of Listeria monocytogenes in 1.5% of the samples tested. In the case of coagulase-positive staphylococci, non-complying findings were seen in 0.5% of the samples tested; in two cases, staphylococcal enterotoxins were detected. A total of 3.9% of the samples tested for Escherichia coli were non-complying. Escherichia coli, foodborne pathogens, food safety, Listeria monocytogenes, meat and meat products, Salmonella spp. , Staphylococcus aureus, staphylococcal enterotoxins
New Development to Measure Mode I. Fracture Toughness in Rock

Tensile fracture toughness is one of the dominant characteristics of rocks that play an important role in fracture mechanics of rock structures. In spite of the substantial amount of work that has been conducted as suggested methods to determine the fracture toughness of rock in Mode I. , research on new methods are still demanded. The compact tension (CT) specimen is widely used to determine the fracture toughness of metals and is a standard method in accordance with ASTM standard. To conduct similar direct tests in rock, preparation of rock specimen a difficult task and needs some special tools to create notched sample. To address these issues, experimental techniques based direct tensile apparatus have been developed. Developed experimental procedure involves the use of the specimens having a central hole and two notches or cracks at both inner side of proposed specimen. The stress intensity factor formula at the crack tip of a CT specimen can be availed through the literature. However a new expression of stress intensity factor is needed for the developed test in order to account geometry and loading configuration. To develop a new stress intensity factor expression, the numerical models of suggested method were worked out. The focus of the current work is on development of the experimental technique, which involves determining the optimum sample size and shape, loading procedure, fracture toughness for different rock types, and verification of suggested method based on CT test which has been carefully considered in this investigations.
Network position of hosts in food webs and their parasite diversity

Parasites are ubiquitous in ecological communities but it is only recently that they have been routinely included in food web studies. Using recently published data and the tool of network analysis, we elucidate features associated with the pattern of parasitism in ecological communities. First we show here that parasitism is non-random in food webs. Second we demonstrate that parasite diversity, the number of parasite species harboured by a host species, is related to the network position of a host species. Specifically, a host species with high parasite diversity tends to have a wide diet range, occupy a network position close to many prey species, or occupy a network position that can better accumulate resources from species at lower trophic levels. Lastly our results also suggest that a host species with higher vulnerability to predators, being at a network position close to many predatory species, or being involved in many different food chains, tends to be important in parasite transmission.
Evaluation of wheat or corn dried distillers’ grains with solubles on performance and carcass characteristics of feedlot steers

A study was conducted on crossbred steers (n = 275; 376 ± 24 kg) to evaluate performance and carcass quality of cattle fed wheat or corn dried distillers’ grains with solubles (DDGS). The control ration contained 86.6% rolled barley grain, 5.7% supplement and 7.7% barley silage (DM basis). The four treatments included replacement of barley grain at 20 or 40% of the diet (DM basis) with wheat or corn DDGS. Steers were slaughtered at a common end weight of 645 kg with 100 steers randomly (n = 20 per treatment) selected for determination of the retail yield of sub-primal boneless boxed beef (SPBBB). Data were analyzed as a completely randomized design using pen as the experimental unit. Feeding increasing levels of wheat DDGS led to a quadratic increase in dry matter intake (DMI) (P < 0.01), whereas increasing levels of corn DDGS led to a quadratic decrease in DMI (P = 0.01). Average daily gain was not influenced (P = 0.13) by feeding wheat or corn DDGS, but cattle fed corn DDGS exhibited a quadratic increas.
Noise spectroscopy of a quantum-classical environment with a diamond qubit

Knowing a quantum system's environment is critical for its practical use as a quantum device. Qubit sensors can reconstruct the noise spectral density of a classical bath, provided long enough coherence time. Here we present a protocol that can unravel the characteristics of a more complex environment, comprising both unknown coherently coupled quantum systems, and a larger quantum bath that can be modeled as a classical stochastic field. We exploit the rich environment of a Nitrogen-Vacancy center in diamond, tuning the environment behavior with a bias magnetic field, to experimentally demonstrate our method. We show how to reconstruct the noise spectral density even when limited by relatively short coherence times, and identify the local spin environment. Importantly, we demonstrate that the reconstructed model can have predictive power, describing the spin qubit dynamics under control sequences not used for noise spectroscopy, a feature critical for building robust quantum devices. At lower bias fields, where the effects of the quantum nature of the bath are more pronounced, we find that more than a single classical noise model are needed to properly describe the spin coherence under different controls, due to the back action of the qubit onto the bath.

Exploring and Exploiting the Protein S100A7 as a New Target for Breast Cancer Therapy

Abstract : S100A7 is strongly correlated with loss of estrogen receptor alpha (ER) expression in vivo. ER is absent in ~30% of breast cancers, is correlated with poor prognosis, and is a vital marker for response to endocrine therapy. Despite its importance, little is known about the mechanisms that drive the ER? phenotype. Our previous work demonstrated that S100A7 expression can originate from inflammatory stress, and we hypothesized that this could also regulate ER. We have found that the inflammatory cytokine oncostatin-M (OSM) can potently suppress ER expression in MCF7 and T47D breast cancer cells in vitro, while this stimulus strongly enhances S100A7 expression. ER suppression originates at the mRNA level in a mechanism dependent on canonical MAP kinase signaling through the MEKK-ERK1/2 pathway. Loss of ER inhibits the ability of cells to proliferate and express key ER-target genes such as progesterone receptor in response to estrogen. In addition to ER suppression and S100A7 induction, OSM induces changes characteristic of the epithelial to mesenchymal transition (EMT), a process associated with metastasis in vivo. These include loss of E-cadherin and gain of key mesenchymal transcription factors such as snail and twist. Importantly, high expression of the oncostatin-M receptor (OSMR) in patient samples is strongly associated with poor prognosis and downregulation of ER activity, in accordance with our experimental observations.
International Stock Market Leadership and its Determinants

We study time-varying price leadership between international stock markets using a Markov switching causality model. We demonstrate variations in the causality pattern over time, with the US being the dominant country in causing other markets. We examine the factors which determine a country’s role in the causal relationship. For country-specific factors, we show that trades openness increases price leadership. We also find that the lead–lag relationship between the stock markets is weaker during crisis periods, confirming the “wake-up call” hypothesis, with markets and investors focusing substantially more on idiosyncratic, country-specific characteristics during the crisis.
Analysis of the potential of the electrofluid dynamic wind-driven generator

The Electrofluid Dynamic wind-driven generator has been investigated under government supported programs since 1975. The concept features the direct conversion of wind energy into electrical power with virtually no moving parts. Research on this concept has resulted in a detailed operational theory of electrofluid systems and a preliminary conceptual design of a full-scale generator. Analysis of the potential of this concept has established a range for the value indicators and an understanding of its optimization potential and uncertainty. A comparison is made between the value indicators for the Electrofluid Dynamic concept and those of several conventional WECS.
Performance Improvisation for Longevity Maximization with Ant Colony Optimization in Wireless Sensor Network

Wireless sensor network (WSN) technologies are increasingly employed in recent years for monitoring purposes in various fields ranging from the engineering industry to our immediate home environments due to their ability to intelligently monitor remote locations at low cost. Maximization of longevity of wireless sensor networks is possible by using effective transmission strategy. An optimal-distance-based transmission strategy based on ant colony optimization is put forward to fulfill such a maximization aim. Clustering mechanism is one of the popular wireless sensor networks routing mechanisms, and it has proven to be an effective approach for organizing the network into a connected hierarchy . In this paper we have proposed a algorithm in order to increase the longevity of wireless sensor network . The simulations result shows that the network longevity have improved.
