Chemical composition of broad beans (Vicia faba L. ) and development parameters of black bean aphid (Aphis fabae Scop.) under conditions of soil contamination with oil derivatives

The indirect effect of oil derivatives, that is arising from the polluted soil through a host plant to the phytophagous fauna feeding on the plant, has not been investigated before. Hence, our goal has been to assess the effect of used engine oil, diesel fuel and petrol on the chemical composition of broad beans cultivated in soil polluted with these substances and on development parameters, such as fecundity, life span and intrinsic rate of natural increase, in a population of black bean aphid (Aphis fabae Scop.). Doses: 3 g kg-1 (dose I) and 6 g kg-1 (dose II) of an oil derivative per 1 kg of soil d.m. were used. Broad bean (Vicia faba L.) cv. White Windsor was chosen as the test plant used for studying the biology of aphids. When the experiment was completed, an analysis of selected elements (Zn, Fe, Mn, Ni, Cu, Pb, Cd, N, Ca and Mg) was conducted in leaves of broad bean. Soil pollution with petrol in dose I led to a significant decrease in the content of Ca, Mg, Fe, Mn, Zn, Ni and Cu, while causing a marked increase in the Pb content. The double dose of petrol (6 g kg-1) additionally contributed to diminishing the N content, whereas the concentrations of Ni and Cd increased significantly after its application. Soil pollution with diesel fuel, irrespective of a dose, caused a significant decline in the Ca, N, Zn, Ni and Cu concentrations and an increase in the Pb content. Additionally, the dose of 6 g kg-1 led to an increase in the Mg, Fe and Cd content in broad bean plants. Soil pollution with used engine oil dosed at 3 g kg-1 led to a reduction of the Ca, Mg, Fe, Mn, Zn and Cu content, while causing an increase in Pb and a slight increase in N concentrations. The double dose of engine oil caused a decline only in the Ca, Mn, Ni and Cu content. The effect of oil derivatives on the biology of black bean aphid was more pronounced in the second generation. All the analysed substances, except for engine oil in the lower dose, significantly decreased the intrinsic rate of natural increase in the population.
Colonic Capsule Endoscopy

Colonic capsule endoscopy represents a novel technique used to identify colon lesions. Being a noninvasive procedure, with a high patient compliance and minimal side-effects, it can safely be administered to large population groups with different pathologies. When used in conjunction with a self-absorbing patency capsule, it becomes a safe procedure even if obstruction is present, thus eliminating one of the most important risk factor. On the other hand, colonoscopy currently represents the “gold standard” for colon diagnosis and therapy. The technology has not notably evolved in recent years, as its technique remains basically unchanged. Being an invasive procedure, dependent on the experience of the operator, it puts patients under a considerable amount of stress, thus having low patient compliance. Recent studies advanced the possibility of using colonic capsule endoscopy in colorectal cancer screenings as an alternative or a complementary method to standard colonoscopy. We reviewed such literature trying to present accurate data regarding the safety, feasibility and performance of colonic capsule endoscopy when compared with standard colonoscopy.
Accounting for forest management in the estimation of forest carbon
balance using the dynamic vegetation model LPJ-GUESS (v4.0, r9333):
Implementation and evaluation of simulations for Europe

Abstract. Global forests are the main component of the land carbon sink, which acts as a partial buffer to CO2 emissions into the atmosphere. Dynamic vegetation models offer an approach to making projections of the development of forest carbon sink capacity in a future climate. Forest management capabilities in dynamic vegetation models are important to include the effects of age and species structure and wood harvest on carbon stocks and carbon storage potential. This article describes the introduction of a forest management module in the dynamic vegetation model LPJ-GUESS. Different age- and species-structure setup strategies and harvest alternatives are introduced. The model is used to represent current European forests and an automated harvest strategy is applied. Modelled carbon stocks and fluxes are evaluated against observed data at the continent and country levels. Including wood harvest in simulations increases the total European carbon sink by 32 % in 1991–2015 and improves the fit to the reported European carbon sink, growing stock and net annual increment (NAI). Growing stock (156 m3 ha−1) and NAI (5.4 m3 ha−1 y−1) densities in 2010 are close to reported values, while the carbon sink density in 2000–2007 (0.085 kgC m−2 y−1) is 63 % of reported values. The fit of modelled values and observations for individual European countries vary, but NAI is generally closer to observations when including wood harvest in simulations.

INSTITUTO TECNOLÓGICO Y DE ESTUDIOS SUPERIORES DE MONTERREY CAMPUS CIUDAD DE MEXICO “VALUE RELEVANCE OF THE OHLSON MODEL WITH MEXICAN DATA” DOCTORADO EN ADMINISTRACIÓN TESIS PRESENTADA POR: ROCÍO DURÁN VÁZQUEZ ASESOR: DR. HUMBERTO VALENCIA HERRERA

In this study, the value relevance of Mexican accounting variables is tested under econometric terms. The aim of the study is to provide evidence of the ability of Mexican accounting numbers to summarize the information underlying stock prices. The accounting variables used are from companies listed in the Mexican stock market from 1991 to 2003. The value relevance was operationalized using the Ohlson model criteria (1995) from the market-based accounting research field. The methodology employed is that described by Collins, Maydew, and Weiss (1997) and Collins, Pincus, and Xie (1999). The econometric results show that, under Panel Data Analysis, book value and earnings are value relevant in Mexican stock market companies, and only the book value is value relevant under Ordinary Least Squared Regression Analysis. In addition to the Ohlson model results, an alternative model is presented as a better proxy of the value relevance of the characteristics of Mexican information. The first approach was to verify the explanation power of other variables (EBITDA, Dividends, Operative Cash Flow and Net Cash Flow) rather than earnings in the original Ohlson model; however, according to Dechow (1994), none of them were significant because of the accruals importance (earnings). The second approach was to add an additional variable that provides further information to the original Ohlson model. Finally, an operative cash flow variable per share was identified as the third variable to be considered, and together with book value and earnings, constitutes the alternative model. The proposed alternative model was tested under the full-sample and Intangible versus Tangible economical classification. In these tests, the alternative model provides extra information and better statistics than the original Ohlson model. 1 According to T-statistic significance and Adjusted R , under Ordinary Least Square Regression and Generalized Least Square Panel Data criteria. Research line: empirical market based accounting, Ohlson model application with Mexican Data. This study was written in English in order to make easy the comprehension of literature references. 2 Using the first difference information based approach. 3 See the notation on page 5 of this study.

The Synergetic Effect of Silver Diamine Fluoride with Potassium Iodide and Grape Seed Extract on Dentin Remineralization

Purpose: This study was conducted to evaluate the synergetic effect of using silver diamine fluoride containing potassium iodide and grape seed extract on dentin microhardness. Materials and Methods: Sixty freshly extracted human deciduous second molars were enrolled in this study. Sixty dentin discs were cut from the crown and were randomly divided into four groups according to the applied treatment after dentin demineralization, (15 samples each). In the first group, samples were received no treatment, only stored in artificial saliva (positive control), in the second group, samples were treated with silver diamine fluoride containing potassium iodide only, in the second group, samples were treated with grape seed extract only (GSE), in the third group, samples were treated with silver diamine fluoride containing potassium iodide (SDF), whereas in the fourth group, samples were treated with combined therapy of grape seed extract followed with silver diamine fluoride containing potassium iodide (GSE+SDF). Microhardness measurements were taken for each dentin disc at baseline, after demineralization, and after treatment. Results: There was a statistically significant increase in dentin microhardness after each treatment as compared to the demineralized dentin microhardness. The mean percent change of dentin microhardness was statistically significant increased in GSE, SDF, and GSE+SDF groups when compared to the control group. Conclusions: Considering the limitations of this study, monotherapy of GSE, SDF solution, and their combination can be recommended to enhance the micro-hardness of demineralized dentin. SDF applications after GSE improved the micro-hardness of demineralized dentin when compared to the monotherapy of each treatment.

Designing High Performance DSM Systems using In(cid:2)niBand: Opportunities, Challenges and Experiences (cid:0)

Software based DSM systems have traditionally not performed well because of the combined effects of increase in communication, slow networks and the large overhead associated with processing the coherence protocol. Recent modern interconnects like Myrinet, Quadrics and In(cid:2)ni-Band offer reliability, low latency (around 5.0 (cid:1) s point-to-point), and high-bandwidth (up to 10.0 Gbps in 4X In(cid:2)ni-Band). Besides the traditional channel-based send/receive communication primitives, these networks also support memory-based communication primitives like RDMA Read and RDMA Write allowing remote reading and writing of data respectively without receiver intervention. In(cid:2)niBand also provides hardware support for remote atomic operations (fetch and add). These architectural supports open up new challenges in exploring low-overhead, high performance, and scalable cache coherency protocols for software DSM systems. In this paper, we take on such a challenge and develop an enhanced coherency protocol by taking advantage of RDMA Read and atomic fetch-and-add primitives. This enhanced protocol (termed as ARDMAR - Atomic and RDMA Read) helps to reduce the load at the default and actual home nodes on a page fetch request, leading to reduced page fetch time and handler processing time. The ARDMAR protocol is integrated into the HLRC DSM system and evaluated on a 16-node In(cid:2)niBand cluster for (cid:2)ve different applications (Barnes, Radix Sort, Integer Short, 3D FFT, and Water) with various problem sizes. For 16-node systems and various problem sizes, the ARDMAR protocol is demonstrated to reduce the application-level execution time by a factor of up to 2.25. These results demonstrate potential to build high performance DSM systems us-ing modern clusters with In(cid:2)niBand.

Biologics in non-infectious uveitis past, present and future

Our increase in knowledge of the pathophysiology of non-infectious uveitis (NIU) and other immune-mediated diseases has been mirrored over the last two decades by the expansion of therapeutic options in the realm of immunosuppressive medications. Principal among these advances is the emergence of biologics, which offer the promise of targeted therapy and the hope of reduced toxicity when compared to corticosteroids and “standard” immunosuppression. Among the biologics, monoclonal antibodies blocking tumor necrosis factor alpha (TNF-α) have been shown to be a very effective therapeutic target for uveitis and many associated systemic inflammatory diseases. Multiple TNF blockers have shown benefit for uveitis, and in 2016, adalimumab became the first biologic and non-corticosteroid immunosuppressive to obtain Food and Drug Administration (FDA) approval in the treatment of NIU. Although effective, TNF blockers are not universally so, and safety concerns such as infection and demyelinating disease must be carefully considered and ruled out prior to their use, especially in patients with intermediate uveitis with which multiple sclerosis is a known association. Ongoing study has identified novel targets for regulation in the treatment of immune-mediated and inflammatory diseases. Interferons, interleukin and Janus kinase inhibitors in addition to antibodies targeting T cell and B cell activation highlight the expanding field of treatment modalities in NIU. Ongoing study will be required to better determine the safety and efficacy of biologics in the armamentarium of immunosuppressive treatments for NIU.

Application of Independent Component Analysis for the Study of Flame Dynamics and Cyclic Variation in Spark Ignition Engines

ABSTRACT This article reports on the application of independent component analysis (ICA) to line-of-sight, cycle-resolved images of luminosity during combustion, acquired in an optically accessible engine. The experiments are conducted on a port fuel injection spark ignition (PFI SI) engine. The analysis identifies the independent components related to the underlying phenomena of the combustion process. The components, along with their corresponding time dependent coefficients, are used to characterize the morphological evolution of the luminous combustion during a single cycle and over a number of cycles. When ICA is applied to a single cycle, independent structures are identified, clearly separated in time, and related to the spatial distribution in the high-luminosity zone. The corresponding coefficients correlate well with the integral flame luminosity, and characterize the time evolution of the combustion morphological pattern in the chamber. The analysis over several cycles shows that independent components contain information about the dominant luminosity shapes of the cyclic variations. Mutual correlation of the corresponding components for successive cycles is found to be relatively low as expected, due to the high spatial variability of the combustion process in spark ignition engines. This is mainly due to the combustion of fuel pockets segregating in the combustion chamber as a consequence of the erratic behavior of the port-fuel injection process. The procedure is applied to more than one sequence of cycles under different experimental conditions. The method proves to be a relatively fast and detailed new means of non-intrusive analysis of the complex combustion processes taking place in the engine.
Comparison of the transActivation Capabilities of the Human T-Cell Leukemia Virus Type I and II X Proteins

The mechanism of cellular transformation by the human T-cell leukemia viruses (HTLVs) is thought to involve a novel retrovirus gene known as X. The X gene is essential for HTLV replication and acts by enhancing transcription from the viral long terminal repeat. By using the HTLV type I and II X gene-coding regions inserted into a highly efficient expression vector, we directly compared the efficiencies of the two X proteins to trans activate the HTLV type I and II long terminal repeats. We demonstrate that the two X proteins have different patterns of trans activation. The patterns were highly reproducible in all mammalian cells tested. A different pattern of activation was observed in avian cells. These results suggest that the mechanism of trans activation involves specific cellular factors that are highly conserved throughout mammalian species but different in avian cells. Understanding the mechanism of trans activation by the X gene product may provide insights into mechanisms of cellular transformation by HTLV.
