Incorporating Consumer Insights into the UK Food Packaging Supply Chain in the Transition to a Circular Economy
Authors: Clark Nikki , Trimingham Rhoda , Wilson Garrath T.
Published: July 2020

The growth of eating lunch purchased out of the home has led to an increased need for pre-packaged food-to-go products. Single-use plastic packaging is frequently chosen for its food safety and convenience attributes; however, the material format is under scrutiny due to concerns over economic waste and environmental impact. A circular economy could transform linear make-use-dispose supply chains into circular systems, ensuring the cycling of valuable plastic resources. However, there has been limited research into how consumers will behave within circular economic systems. Understanding consumer behaviour with packaging disposed out of the home could aid designers in developing solutions society will adopt in the transition to a circular economy. This study evaluates the application of behaviour research methods, and the behavioural insight outputs, with stakeholders from the UK food-to-go packaging supply chain. A novel co-design workshop and business origami technique allowed multiple stakeholder groups to collaboratively discuss, evaluate, and plan how consumer behaviour techniques could be used within their supply chain packaging development process. Although all stakeholders identified strengths in incorporating behaviour studies into the development process, providing essential knowledge feedback loops, barriers to their application include the cost and time to implement, plus the existing inconsistent UK waste infrastructure.
Exploring the Impact of Dockless Bikeshare on Docked Bikeshare—A Case Study in London
Authors: Feng Dongdong , Cheng Lin , Du Mingyang
Published: July 2020

As a green and sustainable travel mode, the bikeshare plays an important role in solving the “last-mile” problem. The new dockless bikeshare system (DBS) is widely favored by travelers, and the traditional docked bikeshare system (BS) is affected to a certain extent, but the specific circumstances of this impact are not yet known. To fill the knowledge gap, the objective of this study is to measure the impacts of DBS on London cycle hire, which is a type of BS. In this study, the travel data of 707 docking stations in two periods, i.e., March 2018 and March 2017, are included. A spatial-temporal analysis is first conducted to investigate the mobility pattern changes. A complex network analysis is then developed to explore the impact of DBS on network connectivity. The results suggest a significant decrease of 64% in the average trip amounts, with both origins and destinations in the affected area, and the trips with short and medium duration and short and medium distances are mainly replaced by DBS. DBS also has a considerable impact on the structure and properties of the mobility network. The connectivity and interaction strength between stations decrease after DBS appears. We also concluded that the observed changes are heterogeneously distributed in space, especially on weekends. The applied spatial-temporal analysis and complex network analysis provide a better understanding of the relationships between DBS and BS.

Life cycle assessment (LCA) tools have been used by governments and city administrators to support the decision-making process toward creating a more sustainable society. Since LCA is strongly influenced by local conditions and may vary according to various factors, several institutions have launched cooperation projects to achieve sustainable development goals. In this study, we assessed the potential environmental enhancements within the production of road materials applied to the road network of Münster, Germany. We also compared traditional pavement structures used in Münster and alternative options containing asphalt mixtures with larger amounts of reclaimed asphalt pavement (RAP). Although the case study was conducted in Münster, the data collected and the results obtained in this study can be used for comparison purposes in other investigations. In the analysis, we considered all environmental impacts from raw material extraction to the finished product at the asphalt plant. Two environmental indicators were used: non-renewable cumulative energy demand (nr-CED) and global warming potential (GWP). The results show that using RAP increases the consumption of energy but potentially decreases the environmental impacts in terms of the nr-CED and GWP associated with the production of asphalt materials.
The Impact of Disasters on a Heritage Tourist Destination: A Case Study of Nepal Earthquakes
Authors: Min Jihye , KC Birendra , Kim Seungman , Lee Jaehoon
Published: July 2020

This study examines the degree of macroeconomic recovery of the Nepal tourism industry after a natural disaster using the autoregressive integrated moving average model (ARIMA). The study investigated the case of Nepal’s earthquakes in 2015 and examined the impact of the earthquakes on tourism inflows and GDP using time series data from 1990 to 2018. The results show that the increasing trend in the number of tourists changes in the post-earthquake period. In particular, the excess in tourist demand by age and purpose of visits after the earthquake indicates natural disaster as a potential reason for a tourism demand boost, often described as dark tourism in literature. This research shows the process of a heritage tourist destination assessing macroeconomic recovery from a natural disaster and fills the gap in the literature regarding purpose-based tourism demand and a link between dark tourism and disaster recovery on a heritage tourism destination.

Authors: Nurek Tomasz , Gendek Arkadiusz , Roman Kamil , Dąbrowska Magdalena
Published: July 2020

Fractional composition, as well as the temperature of the agglomeration process, affect the quality and mechanical properties of briquettes. In this research, shredded forest logging residues were investigated. Compaction tests were carried out for several specially prepared mixtures made of shares of fractions with different particle sizes. The moisture content, density of briquettes, specific work of compaction, mechanical durability, and biomass susceptibility to compaction were analyzed. Studies have confirmed the significant impact of the fractional composition of compacted biomass on its susceptibility to process parameters and the quality of the final product. Statistical analysis confirmed that the density of the briquette, its durability, the specific work of compaction, and the susceptibility of the tested biomass to compaction strongly depend on the particle size of the compacted biomass. An increase in temperature to 73 °C increased specific work by 40% and contributed to the high quality of briquettes in the range from 0.768 to 1.14 g·cm−3.
Unsupervised Anomaly Detection Approach for Time-Series in Multi-Domains Using Deep Reconstruction Error
Authors: Amarbayasgalan Tsatsral , Pham Van Huy , Theera-Umpon Nipon , Ryu Keun Ho
Published: July 2020

Automatic anomaly detection for time-series is critical in a variety of real-world domains such as fraud detection, fault diagnosis, and patient monitoring. Current anomaly detection methods detect the remarkably low proportion of the actual abnormalities correctly. Furthermore, most of the datasets do not provide data labels, and require unsupervised approaches. By focusing on these problems, we propose a novel deep learning-based unsupervised anomaly detection approach (RE-ADTS) for time-series data, which can be applicable to batch and real-time anomaly detections. RE-ADTS consists of two modules including the time-series reconstructor and anomaly detector. The time-series reconstructor module uses the autoregressive (AR) model to find an optimal window width and prepares the subsequences for further analysis according to the width. Then, it uses a deep autoencoder (AE) model to learn the data distribution, which is then used to reconstruct a time-series close to the normal. For anomalies, their reconstruction error (RE) was higher than that of the normal data. As a result of this module, RE and compressed representation of the subsequences were estimated. Later, the anomaly detector module defines the corresponding time-series as normal or an anomaly using a RE based anomaly threshold. For batch anomaly detection, the combination of the density-based clustering technique and anomaly threshold is employed. In the case of real-time anomaly detection, only the anomaly threshold is used without the clustering process. We conducted two types of experiments on a total of 52 publicly available time-series benchmark datasets for the batch and real-time anomaly detections. Experimental results show that the proposed RE-ADTS outperformed the state-of-the-art publicly available anomaly detection methods in most cases.
Formation of the Dynamic Energy Cascades in Quartic and Quintic Generalized KdV Equations
Authors: Dutykh Denys , Tobisch Elena
Published: July 2020

In this study we investigate for the first time the formation of dynamical energy cascades in higher order KdV-type equations. In the beginning we recall what is known about the dynamic cascades for the classical KdV (quadratic) and mKdV (cubic) equations. Then, we investigate further the mKdV case by considering a richer set of initial perturbations in order to check the validity and persistence of various facts previously established for the narrow-banded perturbations. Afterwards we focus on higher order nonlinearities (quartic and quintic) which are found to be quite different in many respects from the mKdV equation. Throughout this study we consider both the direct and double energy cascades. It was found that the dynamic cascade is always formed, but its formation is not necessarily accompanied by the nonlinear stage of the modulational instability. The direct cascade structure remains invariant regardless of the size of the spectral domain. In contrast, the double cascade shape can depend on the size of the spectral domain, even if the total number of cascading modes remains invariant. The results obtained in this study can be potentially applied to plasmas, free surface and internal wave hydrodynamics.
Increased Mitochondrial Fragmentation Mediated by Dynamin-Related Protein 1 Contributes to Hexavalent Chromium-Induced Mitochondrial Respiratory Chain Complex I-Dependent Cytotoxicity
Authors: Ma Yu , Zhang Yujing , Xiao Yuanyuan , Xiao Fang
Published: July 2020

Hexavalent chromium (Cr(VI)) pollution is a severe public health problem in the world. Although it is believed that mitochondrial fragmentation is a common phenomenon in apoptosis, whether excessive fission is crucial for apoptosis remains controversial. We previously confirmed that Cr(VI) mainly targeted mitochondrial respiratory chain complex I (MRCC I) to induce reactive oxygen species (ROS)-mediated apoptosis, but the related mechanism was unclear. In this study, we found Cr(VI) targeted MRCC I to induce ROS accumulation and triggered mitochondria-related cytotoxicity. Cr(VI)-induced cytotoxicity was alleviated by pretreatment of Glutamate/malate (Glu/Mal; MRCC I substrates), and was aggravated by cotreatment of rotenone (ROT; MRCC I inhibitor). Cr(VI) induced excessive mitochondrial fragmentation and mitochondrial dynamin-related protein 1 (Drp1) translocation, the application of Drp1-siRNA alleviated Cr(VI)-induced apoptosis. The cytotoxicity in the Drp1-si plus Cr(VI) treatment group was alleviated by the application of Glu/Mal, and was aggravated by the application of ROT. Drp1 siRNA promoted the inhibition of Glu/Mal on Cr(VI)-induced cytotoxicity, and alleviated the aggravation of ROT on Cr(VI)-induced cytotoxicity. Taken together, Cr(VI)-induced Drp1 modulation was dependent on MRCC I inhibition-mediated ROS production, and Drp1-mediated mitochondrial fragmentation contributed to Cr(VI)-induced MRCC I-dependent cytotoxicity, which provided the experimental basis for further elucidating Cr(VI)-induced cytotoxicity.

Published: July 2020

Climate change is primarily manifested by elevated temperature and carbon dioxide (CO2) levels and is projected to provide suitable cultivation grounds for pests and pathogens in the otherwise unsuitable regions. The impacts of climate change have been predicted in many parts of the world, which could threaten global food safety and food security. The aim of the present work was therefore to examine the interacting effects of water activity (aw) (0.92, 0.95, 0.98 aw), CO2 (400, 800, 1200 ppm) and temperature (30, 35 °C and 30, 33 °C for Fusarium verticillioides and F. graminearum, respectively) on fungal growth and mycotoxin production of acclimatised isolates of F. verticillioides and F. graminearum isolated from maize. To determine fungal growth, the colony diameters were measured on days 1, 3, 5, and 7. The mycotoxins produced were quantified using a quadrupole-time-of-flight mass spectrometer (QTOF-MS) combined with ultra-high-performance liquid chromatography (UHPLC) system. For F. verticillioides, the optimum conditions for growth of fumonisin B1 (FB1), and fumonisin B2 (FB2) were 30 °C + 0.98 aw + 400 ppm CO2. These conditions were also optimum for F. graminearum growth, and zearalenone (ZEA) and deoxynivalenol (DON) production. Since 30 °C and 400 ppm CO2 were the baseline treatments, it was hence concluded that the elevated temperature and CO2 levels tested did not seem to significantly impact fungal growth and mycotoxin production of acclimatised Fusarium isolates. To the best of our knowledge thus far, the present work described for the first time the effects of simulated climate change conditions on fungal growth and mycotoxin production of acclimatised isolates of F. verticillioides and F. graminearum.

Previous studies have reported increased brain deposits of iron in patients with chronic migraine (CM). This study aims to determine the relation between iron deposits and outcome after treatment with OnabotulinumtoxinA (OnabotA). Demographic and clinical data were collected for this study through a prospective cohort study including 62 CM patients treated with OnabotA in the Hospital Clínico Universitario de Santiago de Compostela (Spain). Demographic and clinical variables were registered. Selected biomarkers in plasma during interictal periods (calcitonin gene-related peptide (CGRP) and pentraxin-3 (PTX3)) and neuroimaging changes (iron deposits in the red nucleus (RN), substantia nigra (SN), globus pallidus (GP), and periaqueductal gray matter (PAG), and white matter lesions (WML)) were determined. Subjects were classified in responders (≥50% reduction in headache days) or non-responders (<50%). Responders to treatment were younger (mean age difference = 12.2; 95% confidence interval (CI): 5.4–18.9, p = 0.001), showed higher serum levels of CGRP (≥50 ng/mL) and PTX3 (≥1000 pg/mL) and smaller iron deposits in the GP and PAG (mean difference = 805.0; 95% CI: 37.9–1572.1 μL, p = 0.040 and mean difference = 69.8; 95% CI: 31.0–108.6 μL, p = 0.008; respectively). Differences in PAG iron deposits remained significant after adjusting for age (mean difference = 65.7; 95% CI: 22.8–108.6 μL, p = 0.003) and were associated with poor response to OnabotA after adjustment for clinical and biochemical variables (odds ratio (OR) = 0.963; 95% CI: 0.927–0.997, p = 0.041). We conclude that larger PAG iron deposits are associated with poor response to OnabotA in CM.

Published: July 2020

Mycobacterium tuberculosis genome encodes over 80 toxin–antitoxin (TA) systems. While each toxin interacts with its cognate antitoxin, the abundance of TA systems presents an opportunity for potential non-cognate interactions. TA systems mediate manifold interactions to manage pathogenicity and stress response network of the cell and non-cognate interactions may play vital roles as well. To address if non-cognate and heterologous interactions are feasible and to understand the structural basis of their interactions, we have performed comprehensive computational analyses on the available 3D structures and generated structural models of paralogous M. tuberculosis VapBC and MazEF TA systems. For a majority of the TA systems, we show that non-cognate toxin–antitoxin interactions are structurally incompatible except for complexes like VapBC15 and VapBC11, which show similar interfaces and potential for cross-reactivity. For TA systems which have been experimentally shown earlier to disfavor non-cognate interactions, we demonstrate that they are structurally and stereo-chemically incompatible. For selected TA systems, our detailed structural analysis identifies specificity conferring residues. Thus, our work improves the current understanding of TA interfaces and generates a hypothesis based on congenial binding site, geometric complementarity, and chemical nature of interfaces. Overall, our work offers a structure-based explanation for non-cognate toxin-antitoxin interactions in M. tuberculosis.
Progress in the Production of Virus-Like Particles for Vaccination against Hepatitis E Virus
Authors: Mazalovska Milena , Kouokam J. Calvin
Published: July 2020

Hepatitis E virus (HEV), a pathogen that causes acute viral hepatitis, is a small icosahedral, quasi-enveloped, positive ssRNA virus. Its genome has three open reading frames (ORFs), with ORF1 and ORF3 encoding for nonstructural and regulatory proteins, respectively, while ORF2 is translated into the structural, capsid protein. ORF2 is most widely used for vaccine development in viral hepatitis. Hepatitis E virus-like particles (VLPs) are potential vaccine candidates against HEV infection. VLPs are composed of capsid subunits mimicking the natural configuration of the native virus but lack the genetic material needed for replication. As a result, VLPs are unable to replicate and cause disease, constituting safe vaccine platforms. Currently, the recombinant VLP-based vaccine Hecolin® against HEV is only licensed in China. Herein, systematic information about the expression of various HEV ORF2 sequences and their ability to form VLPs in different systems is provided.

Organized human papillomavirus vaccination (OHPV) in Japan was introduced in 2010 for girls aged 12–16 years who were born in 1994 or later. The rate of OHPV coverage was 70–80%. However, after suspension of the government vaccination recommendation, the coverage dramatically decreased. We aim to investigate the change in prevalence of HPV infection after the initiation of HPV vaccination. We recruited females aged 20–21 years attending public cervical cancer screening from 2014 to 2017 fiscal years (April 2014 to March 2018). Residual Pap test specimens were collected for HPV testing. We compared the prevalence of HPV type-specific infection between women registered in 2014 (born in 1993–1994, including the pre-OHPV generation) and registered in 2015–2017 (born in 1994–1997, the OHPV generation). We collected 2379 specimens. The vaccination coverage figures were 30.7%, 86.6%, 88.4% and 93.7% (p < 0.01) from 2014 to 2017, respectively. The prevalence of HPV16/18 infection significantly decreased from 1.3% in 2014 to 0% in 2017 (p = 0.02). The three most prevalent types were HPV52, 16 and 56 in 2014, and HPV52, 58 and 56 in 2015–2017, respectively. HPV16 and 33 infection rates decreased. On the other hand, the HPV58 infection rate was obviously increased after OHPV from 0.3% to 2.1%. Our study demonstrates that the prevalence of HPV16/18 infection dramatically decreased and the profile of type-specific HPV infection was changed after OHPV.

Background: Over the past decade, many hospitals have adopted hybrid operating rooms (ORs). As resources are limited, these ORs have to prove themselves in adding value. Current estimations on standard OR costs show great variety, while cost analyses of hybrid ORs are lacking. Therefore, this study aims to identify the cost drivers of a conventional and hybrid OR and take a first step in evaluating the added value of the hybrid OR. Methods: A comprehensive bottom-up cost analysis was conducted in five Dutch hospitals taking into account: construction, inventory, personnel and overhead costs by means of interviews and hospital specific data. The costs per minute for both ORs were calculated using the utilization rates of the ORs. Cost drivers were identified by sensitivity analyses. Results: The costs per minute for the conventional OR and the hybrid OR were €9.45 (€8.60-€10.23) and €19.88 (€16.10- €23.07), respectively. Total personnel and total inventory costs had most impact on the conventional OR costs. For the hybrid OR the costs were mostly driven by utilization rate, total inventory and construction costs. The results were incorporated in an open access calculation model to enable adjustment of the input parameters to a specific hospital or country setting. Conclusion: This study estimated a cost of €9.45 (€8.60-€10.23) and €19.88 (€16.10-€23.07) for the conventional and hybrid OR, respectively. The main factors influencing the OR costs are: total inventory costs, total construction costs, utilization rate, and total personnel costs. Our analysis can be used as a basis for future research focusing on evaluating value for money of this promising innovative OR. Furthermore, our results can inform surgeons, and decision and policy-makers in hospitals on the adoption and optimal utilization of new (hybrid) ORs.
Genetic Algorithm with New Stochastic Greedy Crossover Operator for Protein Structure Folding Problem
Authors: Hulianytskyi Leonid , Chornozhuk Sergii
Published: July 2020

Introduction. The spatial protein structure folding is an important and actual problem in biology. Considering the mathematical model of the task, we can conclude that it comes down to the combinatorial optimization problem. Therefore, genetic and mimetic algorithms can be used to find a solution. The article proposes a genetic algorithm with a new greedy stochastic crossover operator, which differs from classical approaches with paying attention to qualities of possible ancestors.

The purpose of the article is to describe a genetic algorithm with a new greedy stochastic crossover operator, reveal its advantages and disadvantages, compare the proposed algorithm with the best-known implementations of genetic and memetic algorithms for the spatial protein structure prediction, and make conclusions with future steps suggestion afterward.

Result. The work of the proposed algorithm is compared with others on the basis of 10 known chains with a length of 48 first proposed in [13]. For each of the chain, a global minimum of free energy was already precalculated. The algorithm found 9 out of 10 spatial structures on which a global minimum of free energy is achieved and also demonstrated a better average value of solutions than the comparing algorithms.

Conclusion. The quality of the genetic algorithm with the greedy stochastic crossover operator has been experimentally confirmed. Consequently, its further research is promising. For example, research on the selection of optimal algorithm parameters, improving the speed and quality of solutions found through alternative coding or parallelization. Also, it is worth testing the proposed algorithm on datasets with proteins of other lengths for further checks of the algorithm’s validity.

Keywords: spatial protein structure, combinatorial optimization, genetic algorithms, crossover operator, stochasticity.

Authors: Abid Ali Alaa Abid Muslam , Dohan Mohammed Iqbal , Musluh Saif Khalid
Published: July 2020

One of the very efficient and resource conservative image processing methodology is with the help of bilateral filters. This technique filters the image without the help of edge smoothing but it does employs spatial averaging in a non-linear way. The filtering technique discussed above is very much dependent on the parameters of its filters. A very slight change in filter parameter values effects the outputs and results in a most drastic manner. In this paper, the author has worked on two contributions. In the applications concerning image denoising, the author has contributed in study of the parameter selection of bilateral filters which are optimal in nature. The contribution number two is about extending the present work i.e. extension of the filters which are bilateral in nature. In this process, the bilateral filtering of images is applied to the lower frequency sub-bands which is also known as approximation sub-band. This sub-band is obtained by using the wavelet transformations. Hence, a new framework for image denoising will be created which will be combination of multiresolution bilateral filtering and wavelets transformation techniques. As a matter of fact, this combination is efficient in contradicting noise from an image.
Development of an efficient mechanism for rapid protocols using NS-2 simulator
Authors: Abdulwahid Sarah N.
Published: July 2020

The delivered effort in this manuscript is grounded on NS-2 (The Network Simulator 2) to implement the congestion control process of classic TCP (Transmission Control Protocol), with new congestion control mechanism. In this paper, a novel congestion control algorithm is offered, which contains of slow-start and congestion avoidance mechanisms. The proposed slow-start algorithm assumes a duplicating and an interpolating approach to the congestion window (cwnd) for each increment instead of the exponential increment used by other TCP source variants such as Reno, Vega, Tahoe, Newreno, Fack, and Sack. Furthermore, the enhanced congestion avoidance algorithm is built by using an improved Additive Increase Multiplicative Decrease (AIMD) algorithm with multi TCP flow facility, to provide an enhanced congestion control algorithm with some valuable properties to improve TCP routine for high speed protocols. The improvement strategy based on merging of slow start, congestion avoidance mechanism that are used in TCP congestion control, to create a new AIMD algorithm with a new relationship between the pair parameters a and b. This paper is also involved in the creation of rapid agent in NS-2 models designed to identify the modified TCP and to configure the NS-2 platform. A fast TCP also includes an innovative scheme to slow the rapid start to help TCP to start faster through the high speed networks and also to postpone the congestion state as much as possible.

Perimeter intrusion detection systems are an integral part of most physical security systems. The mainfocus of the Perimeter Intrusion Detection System (PID) is on the fence intrusion. To secure public and private placessuch as military bases, airports, power station and security related application, the used of perimeter fencing iswidely applicable for isolating and protecting. Fence structures merely prevent a percentage of intrusions orpostpone them. Therefore, to monitor and investigate activities on or around the university, a higher level of securityis needed. The system used major components as Arduino board, 8x8 LED display, ultrasonic sensor, 16x2 LCDdisplay module and speaker. The unauthorized person who tries to intrude the university woulld be sensed, detectedand alarm would generate a signal that an intruder was trying to enter the university. The sound level depended onthe distance, the nearer the intruder and stronger would be the alarm signal. PID system displayed the distance of theobject or personal found in its region on the LCD display. This system was very useful for security applications.Ultrasonic sensor would be searching if there was a motion in its range.

En la Casación Laboral 10956-2017-Tacna, la Corte Suprema establece un criterio para la cuantificación del daño por lucro cesante que está lejos de representar una valoración equitativa del resarcimiento pues, niega la incidencia de que el trabajador labore para otro empleador durante el periodo del despido. Esto es criticado por el autor, debido a que en el proceso, la Corte Suprema demuestra desconocimiento de la regulación referente a la responsabilidad civil contractual al validar un monto indemnizatorio por lucro cesante calculado sin tener en cuenta criterios establecidos en el Código Civil, de aplicación supletoria a las relaciones laborales; incluso, tampoco tiene en cuenta criterios que razonablemente son aplicables en materia de la cuantificación del lucro cesante en la responsabilidad civil.

En el presente trabajo el autor estudia los elementos que determinan la validez de la tercerización, figura que es parte de los procesos de descentralización productiva, y a través de la cual se da la contratación de una empresa especializada denomina contratista o tercerizadora. Para el análisis, se toman en cuenta la Ley que regula los servicios de Tercerización - Ley N° 29245 y; su reglamento, el Decreto Supremo N° 006-2008-TR, con la finalidad de evaluar si la vigente legislación contiene articulados que pueden dar lugar a un alto grado de discrecionalidad, posibilitando que se dé un uso indebido de la tercerización. De esta forma, el autor concluye que debería realizarse la modificación del artículo 2 de la Ley y el artículo 5 de su reglamento, a fin de evitar un uso simulado o fraudulento y, de esta forma, contribuir a la consecución del principio tuitivo.
Apuntes para la historia constitucional peruana. La Constitución de 1920, cien años después
Authors: Centurión Gonzalez Freddy
Published: July 2020

Dentro de la historia del Perú, la segunda etapa gubernativa de Augusto B. Leguía (1919-1930), llamado el “oncenio”, no deja de ser un periodo polémico por sus luces y sombras. Surgido de un golpe de estado, el régimen implementó una reforma constitucional que derogó el texto de 1860 en favor de una nueva Constitución, la de 1920. Aprovechando el centenario de dicho texto, que dio inicio al constitucionalismo social en el Perú, este artículo busca brindar un acercamiento a las circunstancias que marcaron su origen y derogación, las reformas que implementó, y su continuidad en el tiempo.

Одной из основных функций ампелографической коллекции является интродукция. Цель исследований - выделить среди изучаемых на коллекции интродуцированных сортов, наиболее перспективные для качественного виноделия в условиях Нижнего Придонья. Исследования проводились по общепринятым в виноградарстве методикам. Изучение сортов проводили в 2014-2018 гг. на Донской ампелографической коллекции имени Я.И. Потапенко (г. Новочеркасск, Россия). Сорта изучались в укрывной привитой культуре. В статье приводятся следующие показатели по каждому изучаемому сорту - срок созревания, процент плодоносных побегов, средняя масса грозди, урожайность, данные механического анализа (выход сока, процент гребней, кожицы и плотных частей мякоти, семян), масса 100 ягод, кондиции урожая (сахаристость и титруемая кислотность), органолептическая характеристика вина и его дегустационная оценка. По результатам проведенных 5-летних исследований выделены как перспективные 7 белоягодных сортов винограда для качественного виноделия в условиях Нижнего Придонья - Гок изюм, Горули мцване, Грубела, Норок, Рислинг мускатный, Ркацители розовый, Хоца цибил. Эти сорта рекомендуется использовать также для селекции, с целью выведения новых сортов с высокими технологическими свойствами для качественного виноделия.

Introduction is one of the main functions of ampelographic collection. The purpose of the research is to identify in the collection the most promising introduced varieties for high-quality winemaking in the conditions of Lower Don Valley region. The research was conducted using methods generally accepted in viticulture. Grapevine cultivars were studied during 2014-2018 at Ya.I.Potapenko Don ampelographic collection (Novocherkassk, Russia). Varieties were observed in a covered grafted culture. The article provides the following parameters for every variety under study: ripening period, percentage of fruit-bearing shoots, average bunch weight, yield capacity, mechanical analysis data (juice output, percentage of stems, skin and dense parts of pulp, seeds), weight of 100 berries, crop conditions (sugar content and titratable acidity), organoleptic characteristics of wine and its tasting evaluation. As a result of 5-year research, 7 white grapevine varieties were identified as promising for high-quality winemaking in the conditions of Lower Don Valley region - ‘Gok Isum’, 'Gorouli Mtzvanet', 'Groubela', ‘Norok’, ‘Riesling Muscat’, ‘Rkatsiteli Rose’, 'Khotza Tzibil'. These varieties are also recommended for selection in order to breed new varieties with strong technological properties for high-quality winemaking.

Содержание и состав органических кислот, играющих важную роль в формировании вкуса и аромата вина, во многом зависит от штамма дрожжей. Это позволяет рассматривать микроорганизмы как средство биомодуляции кислотности вин. Целью настоящих исследований являлось изучение комплекса нелетучих органических кислот белых столовых сухих вин из винограда сортов Алиготе, Кокур белый и Мускат белый, полученных с использованием шести штаммов дрожжей рода Saccharomyces. Анализ комплекса органических кислот вин осуществляли с использованием ВЭЖХ. Показано, что, несмотря на превалирующую роль сорта винограда в формировании комплекса органических кислот, титруемой и активной кислотности вина, штамм дрожжей также влияет на его формирование. Выявлены особенности комплекса органических кислот вин, полученных на разных штаммах: высокая доля яблочной (33%) и молочной (16%) кислот в винах, полученных соответственно на штаммах Мускат венгерский и Судак; высокая концентрация янтарной кислоты в винах, полученных на штаммах Ленинградская и Мускат венгерский - 1,38 и 1,18 г/дм соответственно, и низкая 0,83 г/дм - на штамме Судак. Полученные результаты послужат базисом в исследованиях по биомодуляции состава органических кислот путем использования разных штаммов дрожжей, как одного из факторов снижения доз диоксида серы в аспекте производства винопродукции с органическим статусом.

The content and composition of organic acids, playing an important role in the formation of wine taste and aroma, largely depend on the yeast strain. It allows us to consider microorganisms as a resource of biomodulation of wine acidity. The purpose of this research was to study the complex of nonvolatile organic acids of white table dry wines made of ‘Aligote’, ‘Kokur Belyi’ and ‘Muscat Blanc’ grape varieties obtained using six strains of the Saccharomyces yeast species. The analysis of the complex of organic acid of wines was carried out using HPLC. It was shown that, despite the predominating role of grape varieties in the formation of organic acids complex, titratable and active acidity of wine, the yeast strain was also effecting its formation. The features of the complex of organic acids of wines obtained with different strains were revealed: high proportion of malic (33%) and lactic (16%) acids in wines obtained respectively with strains ‘Muscat Vengerskiy’ and ‘Sudak’; high concentration of succinic acid in wines obtained with strains ‘Leningradskaya’ and ‘Muscat Vengerskiy” - 1.38 and 1.18 g/dm, respectively, and low 0.83 g/dm with the strain ‘Sudak’. The results obtained will serve as a basis for research of biomodulation of the composition of organic acids by using different yeast strains as one of the factors of reducing the dosage of sulfur dioxide in the aspect of organic wine production.
