Introduction: Breast cancer is the most common type of cancer that affects women. Human epidermal growth factor receptor 2 (HER2) is a gene that plays a significant role in the development of breast cancer. The aim of this study was to compare the survival of HER2-positive breast cancer patients who received Herceptin with those who did not receive it in Yazd, Iran.Materials and Methods: Our study was an analytical cross-sectional study. Sampling was done on all patients with HER2-positive invasive ductal carcinoma (HER2 positive) who were referred to Shahid Sadoughi Hospital or Shahid Ramezanzadeh Hospital from 2003 to 2014. The data were collected using a questionnaire, which included questions on age, type of tumor, tumor grade, recurrence history, tumor size, number of lymph nodes, and whethr Hercepin was received or not received. Data were then entered into SPSS version 18 and analyzed by statistical tests.Results: The mean age of the patients was 50.78 ± 10.75 years. The mean survival time was 61.61 ± 2.93 months, and the mean recurrence time was 104.104 ± 41.3 months. The results also showed that there was no statistically significant difference between the 2 groups, despite the higher mean survival time and less recurrence time in patients receiving Herceptin compared with those who did not receive Herceptin (P>.05).Conclusions: According to the results of this study, the efficacy of Herceptin as a neoadjuvant treatment in the survival of HER2-positive breast cancer patients has not been established.

Published: August 2018

There is growing evidence that food, in particular pollen, limitation is the strongest factor in pollinator decline. We have considered the potential effects of diversity in plant-community attributes as well as variations in the pollen and energy amount on the abundance and frequency of insect visitors to the Lamiaceae species Salvia pratensis L., S. verticillata L., Thymus serpyllum L., Betonica officinalis L. syn. Stachys officinalis (L.) Trevis., and Origanum vulgare L. The species were grown in two different habitat types (dry grassland vs. railway embankment) in the Lublin Upland, Poland. We found significant inter-species, inter-habitat, and inter-year disparities in the pollen mass and total energy amount per unit area. Canonical correspondence analysis (CCA) revealed that the blossom cover, species richness, and diversity noted at the plant community level significantly influenced the distribution of insect visitors to Lamiaceae species. The pollen caloric value and pollen abundance (but not the protein content in the pollen) had a considerable impact on the abundance and frequency of honeybees, bumblebees, and solitary bees in Lamiaceae flowers. Butterflies, beetles and flies did not respond to these factors. The model including all variables explained 66.4% of the observed variance. The studied Lamiaceae species, due to abundant flowering and good pollen nutritional value should be considered in the protocols to improve food resources, especially for social bees; however, disparities in pollen quantity and energy amount should not be ignored.

Published: August 2018

This paper investigates the hedging effectiveness of the International Index Futures Markets using daily settlement prices for the period 4 January 2010 to 31 December 2015. Standard OLS regressions, Error Correction Model (ECM), as well as Autoregressive Distributed Lag (ARDL) cointegration model are employed to estimate corresponding hedge ratios that can be employed in risk management. The analyzed sample consists of daily closing market rates of the stock market indexes of the USA and the European futures contracts. The findings indicate that the time varying hedge ratios, if estimated through the ARDL model, are more efficient than the fixed hedge ratios in terms of minimizing the risk. Additionally, there is evidence that the comparative advantage of advanced econometric approaches compared to conventional models is enhanced further for capital markets within peripheral EU countries

Published: August 2018

Biomedical Nanotechnology (BNT) has rapidly become a revolutionary force that is driving innovation in the medical field. BNT is a subclass of nanotechnology (NT), and often operates in cohort with other subclasses, such as mechanical or electrical NT for the development of diagnostic assays, therapeutic implants, nano-scale imaging systems, and medical machinery. BNT is generating solutions to many conventional challenges through the development of enhanced therapeutic delivery systems, diagnostic techniques, and theranostic therapies. Therapeutically, BNT has generated many novel nanocarriers (NCs) that each express specifically designed physiochemical properties that optimize their desired pharmacokinetic profile. NCs are also being integrated into nanoscale platforms that further enhance their delivery by controlling and prolonging their release profile. Nano-platforms are also proving to be highly efficient in tissue regeneration when combined with the appropriate growth factors. Regarding diagnostics, NCs are being designed to perform targeted delivery of luminescent tags and contrast agents that enhance the NC -aided imaging capabilities and resulting diagnostic accuracy of the presence of diseased cells. This technology has also been advancing the ability for surgeons to practice true precision surgical techniques. Incorporating therapeutic and diagnostic NC-components within a single NC can facilitate both functions, referred to as theranostics, which facilitates real-time in vivo tracking and observation of drug release events via enhanced imaging. Additionally, stimuli-responsive theranostic NCs are quickly developing as vectors for tumor ablation therapies by providing a model that facilitates the location of cancer cells for the application of an external stimulus. Overall, BNT is an interdisciplinary approach towards health care, and has the potential to significantly improve the quality of life for humanity by significantly decreasing the treatment burden for patients, and by providing non-invasive therapeutics that confer enhanced therapeutic efficiency and safety
Incorrect Methodology for Agri-Environmental Measure - Multifunctional Field Margins - As Limitation for Enhancement of Environment in Slovakia
Authors: Palšová Lucia
Published: August 2018

Agri-environment measures are a key element for the integration of environmental concerns into the Common Agricultural Policy. They are designed to encourage farmers to protect and enhance the environment on their farmland by paying them for the provision of environmental services. Rural Development Programme 2014 – 2020 introduced an agri-environmental measure for multifunctional field margins (biostrips on arable land), which contributes to increasing biodiversity, to protection of basic environmental elements and it also serves as prevention for climate change. Since so far no farmer asked the Agricultural Paying Agency for commitment, the objective of the paper was to assess the design and accuracy of calculation of the agri-environmental and climatic measure - the multifunctional field margins in the conditions of Slovakia. The research results show that the calculation methodology is incorrectly set and it does not compensate for the farmer’s loss on farm yields.

Published: August 2018

The main subject of this study are molecular structures and optical properties of boron-doped diamond films with [B]/[C]ppm ratio between 1000 and 10 000, fabricated in two molar ratios of CH4-H2mixture (1 % and 4 %). Boron-doped diamond (BDD) film on the fused silica was presented as a conductive coating for optical and electronic purposes. The scanning electron microscopy images showed homogenous and polycrystalline surface morphology. The Raman spectroscopy confirmed the growth of sp3
diamond phase and sp2carbon phase, both regular and amorphous, on the grain boundaries, as well as the efficiency of boron doping. The sp3/sp2ratio was calculated using the Raman spectra deconvolution method. A high refractive index (in a range of 2.0 to 2.4 at λ= 550 nm) was achieved for BDD films deposited at 700 °C. The values of extinction coefficient were below 1.4 at λ= 550 nm, indicating low absorption of the film

Published: August 2018

This article classifies housing development according to horizontal and vertical intensity in the administrative capitals of each of the Polish provinces. Moreover, the distribution of individual types of residential development is assessed on the example of Warsaw. The function of the place of residence is an elementary urban function which translates itself into a large share of residential development in its structure. It assumes different forms which depend on many factors, such as the location in the given region of the world, conditions of the natural environment, housing tradition or location in the city. It should be borne in mind that cities tend to be heterogeneous urban organisms in which different periods of their development overlap which is reflected in the variations in the appearance of development in its individual parts. The character of buildings changes together with distance from the city centre: the farther from it, the less urban the development tends to be, gradually turning into a rural one both within the city boundaries and outside them. The distribution of residential buildings was analysed with the use of measures of centrography, i.e. centre of gravity, standard deviation and the standard deviation ellipse. Data on residential buildings in the cities analysed was obtained from Polish official geodetic and cartographic databases (państwowy zasób geodezyjny i kartograficzny [PZGiK]) – in particular, Database of Topographic Objects. In turn, layers with land parcels come from the Land-Parcel Identification System [LPIS]. Further analyses use information regarding the vertical and horizontal intensity according to the classification proposed by S. Liszewski (1978).

Published: August 2018

Bacteria adapt to changing environmental conditions by rapid changes in their transcriptome. This is achieved not only by adjusting rates of transcription but also by processing and degradation of RNAs. We applied TIER-Seq (transiently inactivating an endoribonuclease followed by RNA-Seq) for the transcriptome-wide identification of RNase E cleavage sites and of 5′ RNA ends, which are enriched when RNase E activity is reduced inRhodobacter sphaeroides. These results reveal the importance of RNase E for the maturation and turnover of mRNAs, rRNAs, and sRNAs in this guanine-cytosine-rich α-proteobacterium, some of the latter have well-described functions in the oxidative stress response. In agreement with this, a role of RNase E in the oxidative stress response is demonstrated. A remarkably strong phenotype of a mutant with reduced RNase E activity was observed regarding the formation of photosynthetic complexes and phototrophic growth, whereas there was no effect on chemotrophic growth.

This paper investigates the role of Islam in Malaysia’s as a reform on soft power tools under the leaderships of Malaysia’s fifth Prime Minister, Tun Abdullah Badawi. The study emphasis the reform in policy making, philosophies and approaches of the premiers in developing an understanding of the importance of Islam’s role in Malaysia’s public diplomacy. The research also determines the influence of international events in the public diplomacy policies. The study takes a constructivist approach and includes faith diplomacy into the realm of public diplomacy. This study has achieved its objective of understanding Islamic public diplomacy in Malaysia’s administration and should be useful for developing future policies of public diplomacy for domestic and international consumption. It is an interesting reflection of this study that the common perception that Abdullah’s public diplomacy was not successful is incorrect; this perception is founded on the labelling that Abdullah’s version carried, which is because Abdullah, true to his character and personality, embraced and enriched previous premiership Islamization principles, without wanting to change them. Though there are arguments as discussed that Islam Hadhari declined, it only declined in the domestic context. In the international arena it appealed to a much wider audience.

Authors: Pavlikov A. , Kochkarev D. , Garkava O.
Published: August 2018

The concept of the design strength of reinforced concrete in bending elements is proposed. This concept can be considered a generalized description of concrete. Such approach makes it possible to consider not only the separate strength of concrete and reinforcement, but also their interaction. The design strength of reinforced concrete is determined by ratio of force, which causes destruction of the standard reinforced concrete specimen, to the corresponding geometric characteristic. It was found that using the introduced concept the calculation of reinforced concrete elements can be reduced to well-known formulas of the strength of materials. It is based on generally accepted hypothesis and stress-strain diagrams of materials. The engineering method is developed, which allows to calculate the strength of the bending reinforced concrete elements of rectangular and circular cross-sections equally simple.

In the work it was made analysis of stiffness influence of upper basis construction and compliance of basics on stress−strained state of monolithic slabs and capabilities to simplify the design scheme of slabs. Two building options were considered: the one with different design: frame and frameless, the second with homogeneous and heterogeneous bases. It is established that in frame buildings only incomplete modeling of slabs shows adequate quality and does not make significant changes in constructive solution in comparison with the full simulation. For frameless buildings ignoring rigidity of upper basis and constructions compliance structures and foundations not only leads to some excess reinforcement plates, but also to the quality discrepancy reinforcement, particularly in patchy basis.

Methods for determining the teeth total skew angle crown engagement considering errors from manufacturing and from mutual arragement of pinion and coronal wheel of an open gearing are implemented. On the basis of experimental data, the possible range of the total skew angle has been determined for different conditions under which large-sized rotating aggregates are operated.
Algorithm and techniques of calculation operated for a long time rotating aggregates during transitive and steady-state regimes of electromechanical drive mechanism operation, non-uniformity of the turn angle of the coronal wheel were considered. Practical recommendations for design improvement of an open gearing and for a system of kinematic parameters adjustment of large-sized rotating aggregates drive mechanism are suggested.

It has been established that repair of quarry excavators should be carried out directly on site. In this case, the use of jacks for weighing the rotary platform of excavators Bucyrus RH340 and Terex RH200 models for repair of running equipment is impossible because of their design features. This type of repair is suggested to be performed as an excavator based on the design developed by the authors. The installation of the excavator on the support structure is carried out by its working equipment. The supporting structure is suggested to be made in the form of two identical fragments for its unification regarding the base of excavators and the convenience of transporting to the site of work. The suugested method of fixing the excavator to the support structure prevents it from being displaced from the impact of seismic loads during blasting operations. The investigation of the stress-strain state of the supporting structure was carried out using the complex of finite-element analysis.

The article presents the results of experimental tests of compressed tubular elements with demountable joints investigated on the central and noncentral compression (with eccentricities 0, 0,25 and 0.5 from the diameter of the sample) and numerical simulation by the finite element method. The obtained results were compared for similar samples and their models. For which using numerical simulation in the Femap software system a stress-strain state was investigated and graphical representations of principal stresses were presented. For comparison the tensions that arose when the shell's steel pipe was reached the yield strength were selected. The mean square deviation and the coefficient of variation of the data obtained varied in the range of 5 – 7%, which indicates the correspondence of the results and allows further research of partial replacement of experimental tests with numerical simulation

Published: August 2018

The strength design method of concrete and reinforced concrete elements is expounded in this article. The experimental program included the study of the strain condition and failure load determination for considered types of elements. The strength design method is expounded for concrete and reinforced concrete elements by means of variation method in the concrete plasticity theory that was developed in Poltava National Technical Yuri Kondratyuk University. There are the results of experimental investigation for truncated concrete wedges that simulate work of concrete compressed zone above dangerous inclined crack, Hvozdev specimens and crucial keys as well as beams. Also all elements were made of higher strength concrete in order to test the applicability of given method to these elements. The results of the experimental research have confirmed the applicability of plasticity zones assumed in the theoretical solutions. The theoretical strength is well coordinated with the experimental one. The failure character of reinforced concrete beams has been discovered. It has not differed from the flexure elements failure by cross section made of conventional concrete.

The forces of negative friction or loading forces of friction on the piles develop due to additional deformations of near pile array and they cannot be more force of resistance on the side of pile in rest, that is formed due to own weight of the ground founding. The paper presents the results of laboratory experimental research of loading forces of friction acting on the lateral surface of the piles without taking into account the vertical load (being relatively at rest) and provided an analysis of methods for detection of negative friction forces (loading forces) acting on the lateral surface of the pile, with the appointment of their load-bearing capacity. The researches have confirmed the theoretical statement about the equality of the loading forces of friction to ground resistance forces under the action of the torque load but not the pulling load, as it is suggested in the modern standards.

The problem of the Ukrainian housing stock energy performance is under consideration. Analysis of the outer walling thermal protection condition has been performed for the basic building construction solutions through the example of Poltava. The housing stock is represented by brick, large-block and panel system buildings, erected in the 50–80-th of the last century. The actual values of heat transfer resistance of the outer walls, windows, covers and other building enclosure are 3–5-fold less than the permissible minimum dimension according to the present-day requirements. The article presents recommendations for thermal modernization of the outer walls in accordance with their construction design, attic and basement floors (over the unheated basement), as well as transparent outer structures according to the present-day standard requirements.
