Regulation of Gene Expression by Quantitative Real Time PCR in Low DoseIsotretinoin Treated Acne Patients

Acne vulgaris is a common human skin disorder, hunting the younger age groups of people ranging from 10-35 years. It is not a deadly disease, but it is a major fact, that most of the suicides in adolescents are due to acne vulgaris. Accumulation of Propionibacterium acnes, sebum production, follicular hyper keratinisation and inflammation are some of the significant causes of pathogenesis of acne. Many medications including antibiotics like tetracycline, minocycline, erythromycin, clindamycin are given to the patients, but due to improper medication habit of the patient and certain resistance mechanisms of smart pathogens leads to the resistance of such bacteria against these antibiotics. Till date, isotretinoin and retinoic acid, are the best treatment for Acne vulgaris. This study was undertaken to analyze the regulation of genes expression after 1 and 8 weeks of isotretinoin (dose: 0.5 mg/kg/ day) treatment given toacne patients. Upregulation in the expression of some prime genes like LCN2, KRT23, SERPINA3 accounts for the initiation of the immune response against the pathogens causing acne. Down regulation of genes like PDE6A, COL1A1, ALOX15B, MMP-2, INSIG1 etc. again demonstrates that the gene products which can convert sebum, fats and cholesterol to triglycerides would no further be beneficial for P. acnes inhabitation. The aim of this study was to understand the action of isotretinoinin the regulation of gene expression in acne patient.
Topology Optimization of a Piezoelectric Energy Harvester

We use a thin piezoelectric layer attached to a mechanical plate to harvest mechanical energy as available at the vibrating skin of machinery. By modifying the material distribution of the piezoelectric layer the resonance frequency of the energy harvester is adjusted to maximize the objective function. In this paper the electric energy and the electric potential is maximized. This topology optimization problem is performed by a variant of the SIMP (Solid Isotropic Material with Penalization) method which determines for every finite element cell if it is better to have piezoelectric material at that location or not. Numerical results are shown for single frequency pressure excitations from a broad frequency range. The objective functions electric potential, electric energy, energy conversion factor and mean transduction are discussed.
Cradle Laser Source Beam Steerer Beam Splitter Detector Beam Dump Rotating Arm Rotation Stage Chopper

We compare performance of various analytical retroreflecting BRDF models to assess how they reproduce accurately measured data of retroreflecting materials. We introduce a new parametrization, the back vector parametrization, to analyze retroreflecting data and we show that this parametrization better preserves the isotropy of data. Furthermore, we update existing BRDF models to improve the representation of retroreflective data.
Carbon nanotube/silicon hybrid heterojunctions for photovoltaic devices

The significant growth of the Si photovoltaic industry has been so far limited due to the high cost of the Si photovoltaic system. In this regard, the most expensive factors are the intrinsic cost of silicon material and the Si solar cell fabrication processes. Conventional Si solar cells have p-n junctions inside for an efficient extraction of light-generated charge carriers. However, the p-n junction is normally formed through very expensive processes requiring very high temperature (~1000°C). Therefore, several systems are currently under study to form heterojunctions at low temperatures. Among them, carbon nanotube (CNT)/Si hybrid solar cells are very promising, with power conversion efficiency up to 15%. In these cells, the p-type Si layer is replaced by a semitransparent CNT film deposited at room temperature on the n-doped Si wafer, thus giving rise to an overall reduction of the total Si thickness and to the fabrication of a device with cheaper methods at low temperatures. In particular, the CNT film coating the Si wafer acts as a conductive electrode for charge carrier collection and establishes a built-in voltage for separating photocarriers. Moreover, due to the CNT film optical semitransparency, most of the incoming light is absorbed in Si; thus the efficiency of the CNT/Si device is in principle comparable to that of a conventional Si one. In this paper an overview of several factors at the basis of this device operation and of the suggested improvements to its architecture is given. In addition, still open physical/technological issues are also addressed.
Possible Effect of Merger and Acquisition on Brand Equity: A Case Study of the IT Industry in South Korea

This study focuses on how mergers and acquisitions (M&A) affect the consumer’s buying behavior, specifically the consumer’s perception, of both the parent and acquired brand in the IT industry. The empirical test of the theoretical model was conducted using data collected through a 5-point Likert-scaled survey administered to a sample of 512 university students in South Korea. The students were selected as respondents in order to increase the homogeneity of the sample and to minimize random error caused by selecting the general public. The survey was designed using real examples. Specifically, the first version of the survey used the “Facebook & WhatsApp” case, and the second version used the “Microsoft & Skype” case. Quantitative methodology was employed, using multi-group path analyses for testing the hypotheses developed. The results confirm that brand awareness and perceived brand value are important sources of brand equity and that the effects of these two components on brand equity after M&A are significantly larger than before M&A. The study provides insights into important issues regarding brand equity and how to strengthen the evaluation of M&A of online companies, which could also be useful for brand managers.
Viruses in Oklahoma Euphorbia marginata

A survey of non-cultivated plants of the Tallgrass Prairie Preserve of Oklahoma for viruses used young leaf tissue for analysis of virus sequence signature content. To assess whether tissue selection may affect the results of such a survey, Snow-on-the-mountain (Euphorbia marginata Pursh) plants growing along roadsides of Payne Co., Oklahoma, were sampled during the fall of 2007. Specimens of upper leaves, lower leaves, white foliar bracts and fruits were separately processed to obtain nucleic acid preparations from virus-like particle fractions of plant homogenates. Signatures of two viruses, a comovirus and a tymovirus, Asclepias asymptomatic virus (AsAV), both also found on the Tallgrass Prairie Preserve, were observed in the sequences of the nucleic acid preparations. Not all tissues of positive plants were consistently positive. In the sequences retrieved, the nucleotides at only five positions differed from those of AsAV obtained from Asclepias viridis. Sequences from bracts and from lower leaves of different plants were more similar to one another than to other sequences from the same plant. © 2009 Oklahoma Academy of Science.
Post-Newtonian approximation in the test particle limit

Gravitational radiation from a small mass particle orbiting a massive black hole can be analytically studied to a very high order in the post-Newtonian expansion. Thus it gives us useful information on the evolution of a coalescing compact binary star. In this talk, I report on recent progress made in the black-hole perturbation approach.
The Impact of Mineral Nitrogen Fertilization on the Occurrence of Native Diazotrophic Bacteria in Kohlrabi (Brassica oleracea) Shoots and Roots

Biological Nitrogen Fixation (BNF) is a process of great importance in crop production systems, as it provides additional natural sources of mineral nitrogen. BNF is catalyzed by diazotrophs that are identified by the nif operon presence comprising the nifH gene that encodes for enzyme nitrogenase synthesis. Thoroughly understanding of factors that influence diazotrophic abundance is crucial for their utilization to enhance sustainability and prevent land degradation in modern agriculture. In this study the impacts of nitrogen fertilization on diazotrophic abundance in Brassica oleracea roots and leaves was investigated in greenhouse experiments by real-time qPCR. One way ANOVA was used to compare means and bivariate Pearson correlation tested for relationships between variables. Increased nitrogen fertilization significantly increased the nitrogen content in leaves but not in roots. No significant changes in nifH gene copy numbers nor in proportion of nifH gene copy numbers were detectable. This indicates no effect of mineral N fertilization on the abundance of total native diazotrophic bacterial numbers in Brassica oleracea plants.
SCUBA-2 imaging Fourier transform spectrometer

We present the conceptual design of an imaging Fourier transform spectrometer (IFTS) for use with SCUBA-2, the second generation, wide-field, submillimeter camera currently under development for the James Clerk Maxwell Telescope (JCMT). This system, which is planned for operation in 2006, will provide simultaneous, broadband, intermediate spectral resolution imaging across both the 850 and 450 µm bands. The spectrometer will offer variable resolution with resolving powers ranging from R ~10 to 5000. When operated at low resolution, the IFTS will provide continuum measurements, well suited to spectral index mapping of molecular clouds, as well as bright nearby galaxies. The IFTS uses a folded Mach-Zehnder configuration and novel intensity beamdividers. The preliminary design, projected telescope performance and scientific impact of the IFTS are discussed. The preliminary design, novel observing modes, projected telescope performance and scientific impact of the IFTS are discussed.
Fact and Fiction of the Bilingual Dictionary

Side by side with this expert opinion there has come down as common exper­ ience of everyone learning a foreign language, trying to communicate in il or trans­ lating from and into it, that foreign words do not only sound different but are nothing but approximations of what we think and feel by means of our own native words. In the glaring light of such a state of affairs, equally striking the philologist as well as the common learner, should the author of a bilingual dictionary ask h.mself seriously whether he has embarked on a Quixotic enterprise. After twenty years of enduring the labours and —to a minor degree— enjoying the satisfactions of comPiling a new English-German dictionary of about 120,000 entries I feel a need now to &ive vcnt to what I would like to call the lexicographer's dilemma. It consists simply in his brave attempt to do the impossible. And this is precisely my theme today; how 1 0 justify the compromise between insupportable claims and legitimate aims, be­ tween the fictions of the bilingual dictionary, what it erroneously sets out to be, and lhe facts that cut it down to its down-to-earth status. To be even more explicit: the fic­ titious claims are the lexical equivalences. The factual aims are the alphabetical en­ tries enabling the user to build hypotheses about the relations between words •n two languages. These relations are a fact, the equations are a fiction. In other words, I would like to focus on what a bilingual dictionary can seriously be expected to achieve, and, on the other hand, what it should not be inadvertently consulted about. To re­ fer to our quotations at the beginning, the dictionary should not purport to be an easy source of word-matches to be exploited by the unwary user filling word-gaps like in a
Negotiation Support for Cooperative Allocation of a Shared Water Resource: Application

Simulation experiments were conducted with the negotiation support system (NSS) presented by Kronaveter and Shamir to evaluate its efficacy in improving the negotiation process, and in getting to an agreed cooperative solution in which both sides gain relative to a simple bargaining process. Two sets of experiments were conducted: (1) with real actors—participants who played the negotiation game; and (2) with simulated actors, where the negotiation process was run through more iterations using objectives and preferences provided by participants. A hypothetical case study was used, in which two adjacent countries are competing for water from a finite common source. The paper describes the experiments and results, and draws conclusions regarding the value of using a negotiation framework in which multiobjective evaluation (using the analytic hierarchy process) and economic evaluation (using the water allocation system) are embedded.
Face Recognition Based on Feature Fusion

A face recognition method based on local feature and global feature is presented. Firstly, local feature of the face are extracted by Gabor wavelet transformation. Then, principal component analysis (PCA) is used to extract the global feature of the face. Finally, these features are integrated as the general features and the final result is given. The experiment shows that the performance of the proposed method is superior to the method based the single feature.
A New Form of Miscanthus (Chinese Silver Grass, Miscanthus sinensis-Andersson) as a Promising Source of Cellulosic Biomass

The Far East population of Miscanthus sinensis (Andersson) was introduced into the West Siberia conditions. There was distinguished a form with a modified structure of the rootage which forms long shoots with leader buds and rapidly colonizes soil, thus forming a continuous and flat (without tussocks) plantation of miscanthus. It is shown that using usual agrotechnologies, it is possible to obtain 10-15 tons of dry biomass of high quality cellulose (about 40%) per ha/year.
Framework for Modeling Statewide Freight Movement Using Publicly Available Data

This paper presents a methodology to model statewide truck trips using publicly available data developed by federal and state organizations. This methodology is applied for the statewide freight planning of North Dakota. In the absence of ample research funding, states, counties and metropolitan planning organizations can resort to these freely available data. A state level commodity-by-industry input-output table customized from a freely available national input-output table is used to disaggregate trips to the traffic analysis zone level. These databases are available nationally; hence, the methodology discussed in this paper can be transferred to other states with relative ease.
Assessment of Banana Postharvest Handling Practices and Losses in Ethiopia

The study was conducted to assess the status of post-harvest handling practices and loss of banana in Ethiopia. The farm level post harvest handling and loss data were collected from 3 major banana producing zones, 5 districts, 10 farmer villages and 14 large-scale commercial farms. The market level post-harvest handling and loss data also encompassed 19 major towns or market outlets scattered throughout Ethiopia. As such a total of 150 small-scale and 14 large-scale growers, 59 wholesalers/ripeners, 53 retailers and 53 consumers were interviewed using structured questionnaires. Secondary data was also collected from written documents and focus group discussions (stakeholders) across the survey areas. Results of the study indicated that the aggregate post-harvest loss of banana was estimated to be 45.78%, of which about 15.68% was incurred at farm, 22.05% at wholesale (including transport from farm gate and ripening), and 8.05% at retailer or purchase to end-user sale levels. Of the causes of postharvest loss accounted during banana transport from the farm gate, impact and finger breakage damages purely accounted to 20% while the remaining 80% also included physiological and other mechanical damages like compression, abrasion, bruising and puncturing. Being a delicate and highly perishable crop, results of the multiple regression analysis indicate that market distance, duration of transport, storage condition, storage duration, duration of ripening, type of ripening rooms, means of bunch transport, experience in banana marketing, etc. were found to be important determinants of the post-harvest loss of banana in Ethiopia. The study generally indicate that even though the country has vast potential for banana production, the supply chain is facing several limitations and constraints that include high yield variability, crop management practices, and high produce perish ability and post-harvest losses throughout the handling stages. These points out the need for increased research and extension services as well as improvement in postharvest handling (transportation, storage, packaging and ripening) and marketing infrastructure and facilities. Keywords: Banana, supply-chain, post harvest handling, postharvest loss, determinants
Citizen Opinion Mining Initiatives in Government Decision Making by Categorizing Citizen Sentiments

: Citizen Opinion Mining (C.O.M) is a type of natural language processing (NLP) for finding the sentiments of citizen on various targeted government policies. Opinion mining techniques can be used for measuring influence facts like citizen behavior, desire, needs that help to improve government services. It’s includes building a system to gather and examine opinions for specific policy, made in weblog posts, comments, stories or tweets. Proposed approach gives brief description how citizens opinions are play important role to make strong decision for any government policy . In our proposed approach we are categorized all the citizen opinion in different categories such as based on their profession (student, professor, common man, businessman) etc. Because if government wants to make decision for specific group of citizen then that group of citizens opinion are most important. The aim of our proposed approach is to make strong decision for citizens.
Stability of rare‐earth‐doped spherical yttria‐stabilized zirconia synthesized by ultrasonic spray pyrolysis

© 2017 The American Ceramic Society Phase stability is one of the crucial requirements for any material that can be used at elevated temperature applications such as thermal barrier coating (TBC). The most traditional TBC material, partially stabilized zirconia, limits the operating temperature due to its phase transformation. Conversely, the low thermal conductivity of fully stabilized zirconia (YSZ) may enable effective reduction in the surface temperature on the coated component, while avoiding deleterious phase transitions, although still being subjected to sintering and grain growth. It has been reported that addition of rare-earths as dopants to YSZ can significantly increase resistance to grain growth at high temperature. Keeping this under consideration, this work investigates the role of rare-earths (lanthanum and gadolinium) in increasing thermal stability of YSZ microspheres, the building blocks for high-temperature photonics for reflective TBC. The spheres were produced by ultrasonic spray pyrolysis, and the doping led to significant improvement of stability by significant inhibition of grain growth. While the individual dopants showed significant growth and sintering inhibition up to 900°C, co-doping with 4% (in mol) of each (Gd and La) led to coarsening resistance up to 1000°C for 3 hours, when particles retained reasonable spherical features with nanometric crystallite sizes.

A NEW METHOD FOR FORECASTING CO2 OPERATION EMISSIONS ALONG AN INFRASTRUCTURE CORRIDOR

In evaluating the sustainability of a new transport infrastructure, an important aspect is the reduction of CO2 emissions that might be produced due to the modal shift. To that end, this article proposes a model based upon the simulation method (in order to determine the specific consumption of the vehicles) and the scenario method (for the prediction of the future demand of traffic). The model has been tested on the case study of the Brenner Corridor. The evaluation is on how the new HC railway line will affect freight transport in various future scenarios relating to 2030, taking into consideration the consequences in terms of traffic redistribution on existing transport infrastructures (the historical railway line and the highway). If compared to the work not being realized (the “minimum” scenario), the results reveal that CO2 emissions can increase of about 80 kt (the “trend” scenario), or decrease of approximately 230 kt (the “consensus” scenario) according to the political decisions that accompany the realization of the new line. In addition, the method makes it possible to determine the specific emissions that are necessary to transport one metric ton of freight along the entire corridor by the different transport modes. Finally, the transfer of freight from road to rail is quantified that is necessary to compensate the emissions originating from the construction of the work.
