Ketogenic Diet and Skeletal Muscle Hypertrophy: a Frenemy Relationship?
Authors: Paoli Antonio , Cancellara Pasqualina , Pompei Pierluigi , Moro Tatiana 
Published: September 2019

Abstract
Ketogenic diet (KD) is a nutritional regimen characterized by a high-fat and an adequate protein content and a very low carbohydrate level (less than 20 g per day or 5% of total daily energy intake). The insufficient level of carbohydrates forces the body to primarily use fat instead of sugar as a fuel source. Due to its characteristic, KD has often been used to treat metabolic disorders, obesity, cardiovascular disease, and type 2 diabetes. Skeletal muscle constitutes 40% of total body mass and is one of the major sites of glucose disposal. KD is a well-defined approach to induce weight loss, with its role in muscle adaptation and muscle hypertrophy less understood. Considering this lack of knowledge, the aim of this review was to examine the scientific evidence about the effects of KD on muscle hypertrophy. We first described the mechanisms of muscle hypertrophy per se, and secondly, we discussed the characteristics and the metabolic function of KD. Ultimately, we provided the potential mechanism that could explain the influence of KD on skeletal muscle hypertrophy.
A Lexical Approach to Estimating Environmental Goods and Services Output in the Construction Sector via Soft Classification of Enterprise Activity Descriptions Using Latent Dirichlet Allocation
Authors: Keogh Gerard 
Published: September 2019

AbstractThe research question addressed here is whether the semantic value implicit in environmental terms in an activity description text string, can be translated into economic value for firms in the construction sector. We address this question using a relatively new applied statistical method called Latent Dirichlet Allocation (LDA). We first identify a satellite register of firms in construction sector that engage in some form of environmental work. From these we construct a vocabulary of meaningful words. Then, for each firm in turn on this satellite register we take its activity description text string and process this string with LDA. Thissoftly-classifiesthe descriptions on the satellite register into just seven environmentally relevant topics. With this seven-topic classification we proceed to extract a statistically meaningful weight of evidence associated with environmental terms in each activity description. This weight is applied to the associated firm’s overall output value recorded on our national Business Register to arrive at a supply side estimate of the firm’s EGSS value. On this basis we find the EGSS estimate for construction in Ireland in 2013 is about EURO 229m. We contrast this estimate with estimates from other countries obtained by demand side methods and show it compares satisfactorily, thereby enhancing its credibility. Our method also has the advantage that it provides a breakdown of EGSS output by EU environmental classifications (CEPA/CReMA) as these align closely to discovered topics. We stress the success of this application of LDA relies greatly on our small vocabulary which is constructed directly from the satellite register.
Spatial structure of the economy – the evolution of nodes and networks in South and Central America
Authors: Czerny Mirosława , Czerny Andrzej 
Published: September 2019

Abstract
The form assumed contemporarily by spatial organization in South and Central America as a network of nodes and spatial linkages represents the outcome for the space of this region of long-acting external influences plus internal conditions that have – at different times in different ways – shaped spatial relationships and the manner in which space in this part of the world is planned. Naturally, the spatial structure of today’s economy is influenced further by globalization, with growing competition for access to resources, be these either mineral deposits or agricultural in nature. These impacts ensure that, notwithstanding the widely-voiced opinion on the need to protect nature in areas of the continent supporting moist tropical forests, and in the high Andes, the governments of the different countries continue to award concessions allowing corporations of global reach to exploit resources of value that are in demand worldwide. This aggressive “resources race” has its serious consequences with regard to the forms and scope the region’s spatial management and organization assume.
These processes ought to be regulated by spatial planning, which is thus failing to play its proper role at regional levels. Those researching South America refer without hesitation to the lack of planning and overexploitation of raw materials, with all the serious consequences this has for society, not least with regard to internal migration, expulsions, the impoverishment of groups in society deprived of their land, and so on.
Mapping India since 1767: transformation from colonial to postcolonial image
Authors: Mondal Tarun Kumar 
Published: September 2019

Abstract
Indian civilization has over 2500 years of mapping tradition. With the establishment of the Survey of India in 1767, British rulers initiated the mapping of colonial India with high precision and accuracy. They started mapping to establish British power and supremacy in the Indian subcontinent that portrayed a British image of India. Following independence in 1947, the Survey of India and other national agencies started mapping India for planning and development. Hence, questions have been raised that, how far British image of India have been transformed into an Indian image. In this context, in this paper an attempt has been made to analyse the mapping of India from the perspectives of transforming a colonial into a postcolonial image. The transformation occurred mainly in terms of purpose i.e. maps as a tool for the expansion of territory to planning, development and governance, from analogue to digital in method and in strategy from restricted to liberal access.
Framing Gender Justice
Authors: Askanius Tina , Hartley Jannie Møller 
Published: September 2019

Abstract
This study examines the media coverage of the #metoo movement in neighbouring countries Denmark and Sweden. A comparative content analysis shows differences in genres, sources and themes across the two samples. Further, the analysis shows that the coverage predominantly positioned #metoo within an individual action frame portraying sexual assault as a personal rather than societal problem in both countries. However, the individual action frame and a delegitimising frame focused on critique of #metoo were more prevalent in the Danish coverage. A framing analysis revealed four different news frames in the coverage: #metoo as (1) an online campaign connecting networked individuals, (2) part of a broader and long-standing social movement for gender justice, (3) an unnecessary campaign fuelled by cultures of political correctness and, finally, (4) a witch hunt and “kangaroo court”. Finally, we discuss and relate these findings to the political and cultural contexts of the two countries and their different historical trajectories for the institutionalisation of feminism and implementation of gender equality policies.
Diffuse reflectance spectroscopy for identification of carcinogen transformation stages in skin tissue
Authors: Shurrab Kawthar , Kochaji Nabil , Bachir Wesam 
Published: September 2019

Abstract
Today, to establish a diagnosis, the patient must undergo a biopsy followed by histopathological diagnosis, which causes unnecessary cost, patient trauma, and time delay to obtain a diagnosis. However, the metastases can be discovered by diffuse reflectance spectroscopy, which is a simple method that investigates the light distribution within tissue. The theme of this paper is the use of diffuse reflectance spectroscopy (DRS) to determine the optical spectrum of hamster specimen’s tissue and to differentiate biological changes due to laser irradiation (scattering, and cell changes) under the skin. DRS measurements were made on healthy and malignant tissue to diagnose the stages of cancer formation using a fiber-optic probe. The results show that malignant tissue is characterized by a significant decrease in diffuse reflectance spectrum compared to normal tissue.

Published: September 2019

Abstract
Signal suppression of the gastrointestinal tract fluids in magnetic resonance cholangiopancreatography (MRCP) has been performed using various natural and chemical substances with the different MRCP pulse sequences. This study aimed to investigate the signal suppressions of the grape syrup and the grape syrup/lemon aqueous solutions in MRCP using the heavily T2-weighted sequences. For this purpose, the potassium, iron and manganese contents of grape syrup were measured by atomic absorption spectroscopy. The grape syrup and the grape syrup/lemon solutions with the various grape syrup percentages were imaged using the heavily T2-weighted sequences of MRCP such as T2 HASTE thick slab and T2 SPACE. MRCP in the volunteers was performed before and 10 minutes after oral administration of the grape syrup solution. The concentrations of potassium, iron, and manganese in grape syrup were 34.8, 2.4 and 1 mg/l, respectively. The in vitro study showed significantly lower signal to noise ratio using the grape syrup samples comparing to the grape syrup/lemon. The effective signal suppression for the in vitro study and considerable enhancement of negative contrast in the post-contrast MRCP was obtained using a T2 HASTE thick slab sequence. As a conclusion, the grape syrup solution can be used for signal suppression of the gastrointestinal tract fluid in MRCP as an oral negative contrast material. A T2 HASTE thick slab sequence produces suitable contrast in MRCP images using the grape syrup solution.

Published: September 2019

Abstract
This study developed a simple wire phantom and an algorithm to automatically measure the modulation transfer function (MTF) in computed tomography (CT) and implemented it to evaluate the effect of focal spot size and reconstruction filter type. The phantom consisted of a resin cylinder filled with water, with a tin wire of diameter 0.1 mm positioned along the center of the cylinder. The automated MTF algorithm used an axial image of the phantom and comprised several steps. The center position of a region of interest (ROI) was automatically determined at the center of the wire image. The pixels were then summed along the y-direction to obtain the profile of the pixel values at a point along the x-direction. Following this, both edges of the profile were made equal to zero. The profile curve was then normalized so that the total of all the data was equal to unity. The normalized profile curve is the line spread function (LSF), and the MTF curve was obtained by taking its Fourier transform. Our system (phantom and algorithm) is able to differentiate the MTFs of CT images from different focal sizes and reconstruction filter types.

Published: September 2019

Abstract
The aeromagnetic data of Idogo, Southwestern Nigeria, have been used to study the lithology and to determine the magnetic source parameters within Idogo and its environs. Idogo lies between latitudes 6°30′N and 7°00′N and between longitudes 2°30′E and 3°00′E. The magnetic anomaly map, the regional geology, the analytic signal and the local wavenumber were used to identify the nature and depth of the magnetic sources in the region. Data enhancement was carried out to delineate the residual features relative to the strong regional gradients and intense anomalies due to the basin features. The estimated basement depth using the horizontal gradient method revealed depths ranging between 0.55 km and 2.49 km, while the analytic signal amplitude and local wavenumber methods estimated depth to the magnetic sources to range from 0.57 km to 4.22 km and 0.96 km to 2.43 km, respectively. Depth computations suggested the presence of both shallow and deep sources. The total magnetic intensity values ranged from 3.1 nT to 108.3 nT. The area shows magnetic closures of various sizes in different parts of the area trending West, with prominence at the centre and distributed East–West.
Cutting Environment Impact on the Aluminium Alloy Machining

Published: September 2019

Abstract
The paper is focused on the experiment where the effects of the cutting environment and feed of drilling on the bores roughness and cylindricity were evaluated. Dry drilling of aluminium alloys (without using cutting fluids) is an environmentally friendly machining process but also an extremely difficult task, which is due to the tendency of aluminium to adhere to the drills made of conventional materials such as high-speed steel; and therefore three cutting environments (namely two different emulsions and compressed air) were used in the experiment. The article demonstrates multicriterial optimization of input factors (cutting environment, feed) for two defined target functions: roughness and cylindricity). The measured values were subjected to mathematico–statistical Analysis of Variance (ANOVA). ANOVA was used for examining the effects of machining parameters and their contribution to the surface roughness and bores cylindricity. The optimal cutting parameters were evaluated for “Smaller-the-Better” quality characteristics of both output responses, as can be seen in our article published previously. Based on the ANOVA, we determined that cutting environment exhibited higher percentage of contribution on bores quality than feed of machining. The results show 77.37 % impact of cutting environment and 8.13 % impact of feed on quality of machined bores.

Published: September 2019

Abstract
The aim of the research described in this paper was to study the impact of the electrical cables slope on the flame out time and the flame spread rate. Measured cables were thermally loaded by methanol flame (diameter of the container was 106 mm) at seven different slopes with respect to the horizontal plane (the slopes were 0° – horizontal orientation, 15°, 30°, 45°, 60°, 75° and 90° - vertical orientation). The first tested electrical cable was a copper three-core power one resistant to the flame spread with circuit integrity of the cable system during 30 minutes under fire (cross-section of each core was 1.5 mm2). The second tested electrical cable was a copper two-core signal one resistant to the flame spread with circuit integrity of the cable system during 30 minutes under fire (cross-section of each core was 0.5 mm2). The first electrical cable did not show reaction to fire class. The reaction to fire class of the second tested cable was B2ca, s1, d1, a1. The obtained results proved that slope had virtually no impact on the flame out time and the flame spread over the tested cable surface (tested cables of all slopes stopped burning after 1 to 5 seconds after methanol flame burned out). Likewise, the flame spread was only negligibly beyond the border of flame action for each cable slope.

Published: September 2019

Abstract
Formaldehyde is a toxic chemical commonly found in the environment. Owing to its increased usage, its incidence has also increased, and there is a need to determine the concentration of formaldehyde for the pollution control purposes. In general, spectrophotometric methods are easy to perform, low-cost, selective and sensitive, but every spectrophotometric method has its advantages and disadvantages, which are an important factor when selecting the method for determination of formaldehyde. Therefore, the aim of the research described in this paper was to compare the current spectrophotometric methods and to summarize their advantages and disadvantages.
Utilization of Spent Coffee Grounds for Removal of Hazardous Substances from Water: A Review
Authors: Blinová Lenka , Sirotiak Maroš 
Published: September 2019

Abstract
Water is one of the most important substances on earth; nowadays, its pollution is one of the main environmental problems. Textile industries pose a significant environmental problem for earth. Firstly, it is due to their huge water consumption, and secondly, they produce a lot of wastewater contaminated with dyes, chemicals, suspended solids, etc. These contaminants can make water unsuitable for the desired purposes (e.g., drinking, watering, washing and showering). The one of the promising methods for the removal of dyes from the contaminated wastewater is adsorption. In this process, we can use low cost waste materials as an adsorbent. This paper presents an overview of utilization of the spent coffee grounds for the removal of dyes from wastewater.
The Importance of Supplier Evaluation in Short Supply Chains
Authors: Pató Gáborné Szűcs Beáta , Kiss Fanni 
Published: September 2019

Abstract
The consideration of supply chains can foster the viability and maintainability of local producers. The formation and retention of the market may be complicated for local producers; therefore it is advisable to take the creation of supply chains into consideration. Constant feedback and evaluation is highly important to maintain successfully operating short supply chains and supplier evaluation forms could act as the starting point of these chains. These forms reflect the strengths and weaknesses of suppliers, based on which the correction of mistakes can be done and the performance of suppliers may be enhanced. The aim of this study is to examine the role of supplier evaluation form and relationships between customers and suppliers in short supply chains, from a local producer’s point of view through a case study. The scientific relevance of this study is to draw particular attention to short supply chains which are and will be of high importance considering local economies. As the case study reveals, it is recommended for the members of short supply chains to use supplier evaluation forms.
What Do Managers Think About the Success Potential of CRM Campaigns?
Authors: Castanheira Bruna Monteiro , Costa E Silva Susana , Martins Carla Carvalho 
Published: September 2019

Abstract
This research analyzes cause-related marketing (CrM) from the perspective of companies. The study aims to achieve a better understanding about what managers think about CrM by analyzing the level of acceptance and usage of this marketing tool, based on the UTAUT model. Using in-depth interviews as research method, we conclude that managers see the benefit of company partaken in initiatives as such, but not necessarily CrM. The reasons why managers choose to participate in Cause-related Marketing initiatives originate from the mix obtained through improving the firm by doing something considered socially positive. CrM was well evaluated by the participants and considered well positioned in terms of acceptance and usage, based on four factors: performance and effort expectancy, social influence, and facilitating conditions. Interviewees expressed excitement towards CrM and believe in it as a powerful tool to improve the firms’ image and consumers feeling towards it. While the literature uses several concepts (Corporate Social Responsibility or Social Marketing), the interviewees emphasize genuine caring and showing interest, time and funds to support consumers social concerns.
The Economic Growth and the Opportunity for the Private Equity Funds to Divest: An Empirical Analysis for Eastern Europe
Authors: Precup Mihai 
Published: September 2019

Abstract
The author studies the private equity divestments in Eastern Europe and tests a long-term relation between these divestments and the real GDP variation. This research paper focuses on a sample covering the period 2000-2013 which considers the dynamics of the private equity divestments during the last financial crisis. The empirical analysis follows the methodology developed by Granger (1969), Toda and Yamamoto (1995), Dufour and Renault (1998), Konya (2004), Foresti (2006) and Onuoha, Okonkwo, Okoro, Kingsley (2018). The analysis shows that Eastern European private equity divestment market is still emerging characterized by high volatilities. The results prove that GDP recession explains in at certain degree the evolution of private equity divestments during the crisis. However, the Granger causality test shows that the information provided by the past variation of the real GDP cannot allow us to predict the short-term movements of private equity divestments in Eastern Europe.
Subgroups of 3-Factor Direct Products
Authors: Neuen Daniel , Schweitzer Pascal 
Published: September 2019

Abstract
Extending Goursat’s Lemma we investigate the structure of subdirect products of 3-factor direct products. We construct several examples and then provide a structure theorem showing that every such group is essentially obtained by a combination of the examples. The central observation in this structure theorem is that the dependencies among the group elements in the subdirect product that involve all three factors are of Abelian nature. In the spirit of Goursat’s Lemma, for two special cases, we derive correspondence theorems between data obtained from the subgroup lattices of the three factors (as well as isomorphisms between arising factor groups) and the subdirect products. Using our results we derive an explicit formula to count the number of subdirect products of the direct product of three symmetric groups.
How Many Weak-Keys Exist in T-310 ?
Authors: Courtois Nicolas T. , Scarlata Matteo , Georgiou Marios 
Published: September 2019

Abstract
T-310 is an important Cold War cipher. The cipher is extremely complex and it outputs extremely few bits from the internal state. A recent paper [Courtois, N. T.: Decryption oracle slide attacks on T-310, Cryptologia, 42 (2018), no. 3, 191–204] shows an example of a highly anomalous key such that T-310 can be broken by a slide attack with a decryption oracle. In this paper, we show that the same attacks are ALSO possible for regular keys which satisfy all the official KT1 requirements. Two other recent papers [Courtois, N. T.—Georgiou, M.—Scarlata, M.: Slide attacks and LC-weak keys in T-310, Cryptologia 43 (2019), no. 3, 175–189]; [Courtois, N. T.—Oprisanu, M. B.—Schmeh, K.: Linear cryptanalysis and block cipher design in East Germany in the 1970s, Cryptologia (published online), December 5, 2018] show that some of the KT1 keys are very weak w.r.t. Linear Cryptanalysis. In this paper, we show that a vast number of such weak keys exist and study the exact pre-conditions which make them weak. In addition we introduce a new third class of weak keys for RKDC (Related-Key Differential Cryptanalysis). We show that the original designers in the 1970s have ensured that these RKDC properties cannot happen for 4 rounds. We have discovered that these properties can happen for as few as 5 rounds for some keys, and for 10 to 16 rounds they become hard to avoid. The main reason why we study weak keys is to show that none of these properties occur by accident, rather that they are governed by precise pre-conditions which guarantee their existence, and countless other keys with the same properties exist. Eventually, this is how interesting attacks can be found.
