DESIGN AND SIMULATION STUDIES OF D-STATCOM FOR VOLTAGE SAG, SWELL MITIGATION
Authors: PATIL D.R. , MADHALE KOMAL K.
Published: December 2020

This paper presents the design of a prototype distribution static compensator (DSTATCOM) for voltage sag mitigation in an unbalanced distribution system. The D-STATCOM is intended to replace the widely used static Var compensator (SVC). The model is based on the Voltage Source Converter (VSC) principle. A new PWM based control scheme has been implemented to control the electronic valves in two level of VSC. The D-STATCOM injects a current into the system to mitigate the voltage sags. In this work, the 6-pulse D-STATCOM configuration with IGBT has been designed using MATLAB SIMULINK. Accordingly, simulations are first carried out to illustrate the use of D-STATCOM in mitigating voltage sag in a distribution system. Simulation results prove that the D-STATCOM is capable of mitigating voltage sag as well as improving power quality of a system.
PINE NEEDLE CHARCOAL BRIQUETTES: RURAL TECHNOLOGY OPTION IN PINE FOREST REGION
Authors: Bharti Vinita , Awasthi Mamta
Published: December 2020

The use of fuel wood, crop residue or cow dung for cooking is widespread in rural India and, as it is not purchased, is often the only option for the rural poor. Besides the low calorific value of these residues, it also affects the health due to indoor air pollution. Briquette technology can reduce this rural problem. Moreover the technology can also
prevent forest fires. They are the annual phenomenon in Himachal Pradesh as the forests are dense and catch fire easily due to natural and man-made reasons. Himalayan forests are rich in Pine trees (Pinus roxburghii Sarg.) and the pine needle is one of the reasons to enhance the forest fire. There is a necessity to handle this forest waste efficiently. This paper attempts to explain the briquetting technology of pine needles and the results showed that a significant improvement in calorific value.

Authors: R NISHA K.C. , BASAVARAJ T.N.
Published: December 2020

This paper presents a high performance, low cost inverter for photovoltaic systems based on Impedance-source concept. Traditional Voltage-source inverter and Current-source inverter has improved to the new Z-source inverter, with a unique X-shaped network in it. This Impedance-source inverter can provide a single stage power conversion concept where as the traditional inverter requires two stage power conversion for renewable energy applications. A new low cost solar cell powered Z-source inverter system is simulated and the results are compared with the traditional Voltage-source inverter
system. Performance analysis, simulation and comparison have been confirmed that the Z-source inverter system is more appropriate for photovoltaic application than their counterparts. Hardware implementation is done to validate the proposed system.
Persistence of Choice as a Reflection of Social Giftedness
Authors: Mishkina Marina
Published: December 2020

The article raises the issue of social giftedness and outlines the necessity of the fundamental study of this phenomenon. The author suggests that social giftedness is reflected in the stability of socially oriented behavior and in more complex and diverse interest in one's own personality: in appreciation of one’s own uniqueness and in participation in a wide range of small and large social groups, where one expresses one’s involvement through personal concern for the groups. The object of the study is to identify the relationship between the stability of one’s choice for the benefit of the group and social giftedness. The proposed hypothesis states that socially gifted schoolchildren tend to make persistent socially oriented choices (with collectivistic cognitive orientation). The hypothesis was tested on a sample of third-graders by means of M. Kuhn and T. McPartland’s test "Who am I" and an experiment of collectivistic/individualistic choices relating to the presence of an authoritative figure. The study confirms that persistence of collectivistic choices is characteristic of socially gifted students.

Authors: Solomatina Viktoriya
Published: December 2020

The article presents the authors’ project of designing a digital educational environment for the actualization and development of creative giftedness in primary school children by means of a network of project activities. The educational environment was designed within the conceptual framework proposed by E. D. Patarakin and based on his idea of using network interactions to support the project method. This approach enables a transition from the concept of "educational environment" to the concept of “educational ecosystem". The model of an ecological system is used in the article to analyze the contemporary educational environment. The empirical material presented in the paper can be implemented in developing new forms of interaction between educational process participants in the context of e-learning.

Authors: Shevchenko Аnatolii , Feshchenko Diana , Zghozinska Oksana , Sachuk Roman , Stravsky Yaroslav , Chala Inna
Published: December 2020

Indicators of physical and chemical composition of raw milk determine the safety and quality of products of its processing (cheese, butter, sour milk drinks). Cow udder hygiene is a guarantee of animal health and one of the most important factors in obtaining high-quality milk. The purpose of the study was to analyze the quality of raw milk in farms in the western region of Ukraine, as well as to determine the impact of dipping procedures using Forticept® Udder Wash (predipping) and Forticept® Udder Forte (dipping) on the quality of milk. In the course of the study, the generally accepted methods of physicochemical and bacteriological research of milk were used. In dairy complexes, where modern hygienically sound milk production technology has been introduced, mastitis affected no more than 9.5% of the herd. At the same time, in other farms with an imperfect industrial scheme, breast pathologies covered 57–80% of the herd. Also, according to authors’ data, the subclinical form of mastitis caused a decrease in milk production to 30 liters per month from one cow. Furthermore, the disease significantly affected the chemical composition, physical and microbiological parameters of milk. In livestock affected by mastitis, the average fat content of milk decreased to 3.17±0.05 %, protein content – 2.93±0.12 %, casein – 2.53±0.17 %. In contrast, the number of somatic cells increased to 769.3±57.34 thousand/cm3. In the experiment, the therapeutic effect of the applied dipping with Forticept® solutions in the subclinical form of mastitis was 50%. The preventive effect almost reached a maximum – 96 %. In fact, the procedure of dipping hygiene of the udder, regardless of the classic or innovative formula of the chosen remedy, significantly reduced the number of cases of hyperkeratosis and prevented the emergence of new ones. The number of udder nipple with pathological changes during the month of dipping decreased by 25%. Intensive udder hygiene also led to an increase in milk fat content (from 13.7 to 17.8%), protein (from 7.3 to 11.9%, P≤0.05) and lactose (from 6.1, P≤0.05 to 2.5%). Moreover, there were a decrease the number of somatic cells to grade milk of high quality (129.76±30.88 thousand/cm3, P≤0.05). Therefore, treatment of the udder by dipping procedures using antiseptic solutions Forticept® prevents cows from mastitis and hyperkeratosis, improves the chemical and bacteriological parameters of milk. In the future, test studies of Forticept® drugs for the use of small cattle are planned.

Published: December 2020

Modernization of the Ukrainian economy under the influence of global post-industrial trends mainstreams the priority of development of science-intensive, high-tech, innovative activities. Modernization creates the preconditions for strengthening competitive positions in the national and global markets. In modern conditions, the issue of assessing the competitiveness of catering companies is relevant. High competitiveness of the enterprise is the main condition of its activity and development. The purpose of the study is to assess the competitiveness of catering companies in the market of catering services in Ukraine. The study proposes methodological approaches to assessing the competitiveness of catering companies. Methodological approaches include continuity of monitoring, determination of parameters, indicators and criteria, selection of optimal evaluation methods. In the process of research the following methods were used: sociological survey, simple ranking, integrated assessment and factor method, system approach method. It was established that methodical approaches to assessing the competitiveness of catering companies include justification and development of a system of socio-economic indicators and criteria (product quality, quality of service, quality and organizational staff, efficiency, efficiency of personnel management, price). Methodological approaches include a set of indicators that form an integrated indicator of competitiveness. This indicator allows to consider objective differences in the dynamics of enterprises, the conditions of use of available resources in the process of forecasting and development of enterprises. A comprehensive diagnosis was carried out based on an integrated indicator of the competitiveness of restaurants on special orders (catering), during which it was determined that its level has a significant differentiation according to the indicators of the studied enterprises, which are due to both external and internal factors, which allows the development of strategic priorities and specific measures to develop the image of the enterprise and increase its competitiveness.

United Kingdom

Published: December 2020

The UK entered 2020 negotiating a new economic relationship with the EU and facing other challenges, including meeting climate targets, dealing with an aging population, and reinvigorating tepid productivity growth. Growth and investment had been weak since the 2016 referendum, and the current account deficit elevated, but unemployment was low, inflation on target, and balance sheets strong. The global pandemic hit the UK hard in March, and the country now faces a second wave. The economic impact has been severe, but helped by an aggressive policy response, jobs have been preserved, businesses kept afloat, and banking sector losses contained. Still, the outlook for the near term is weak, as the economy works through the second wave, Brexit, rising unemployment, and corporate distress. Risks are overall to the downside, centering on the degree of balance sheet damage sustained by households and small and medium enterprises. The pace at which vaccines are able to bring the pandemic under control could be an important mitigating factor.
Euro Area Policies
Authors:   International Monetary Fund. European Dept.
Published: December 2020

The COVID-19 pandemic has led to severe socio-economic dislocations and hardship.
Supported by an unprecedented policy response and by the easing of lockdown
measures as the infection rate moderated, the euro area economy initially recovered
strongly from the pandemic’s first wave. However, a large second wave and reimposition
of containment measures suggest much slower growth momentum in the
near term. The outlook is for a subdued economic recovery and low inflation, with a
significant permanent output loss relative to the pre-crisis trajectory. Uncertainty
remains extremely high, mainly due to different pandemic scenarios, including
regarding the availability and effectiveness of potential vaccines and therapies and
behavioral changes. Output growth is expected to be much lower through 2021Q1 than
projected in 2020 October World Economic Outlook (WEO) but may rebound beyond
then in light of recent promising news on vaccine development.
The key policy challenge is to continue countering the pandemic while facilitating a
robust and inclusive recovery, including by addressing the health crisis, containing
economic scarring, supporting resource reallocation and transformation to greener and
more digital economies, and limiting the crisis’s impact on inequality and poverty. In a
downside scenario, sizable further stimulus would be needed.

Dilin Oluşumu Bağlamında John Searle’ün Doğal Bilinç Kuramı Üzerine Bir İnceleme
Authors: KINAĞ Mustafa
Published: December 2020

Natüralist bir düşünür olarak Searle, bilincin salt dışsal davranışçı yöntemle incelenemeyeceğini, bilincin bu karakteriyle diğer doğal fenomenlerden (gözlemlenebilir fenomenlerden ayrıldığını savunur. Zira ona göre her ne kadar bilinç diğer doğal fenomenler gibi biricik ya da metafizik nitelikler taşımıyorsa da bu husus onun özel bir karakter taşıdığı gerçeğine gölge düşürmez. Nitekim bilinç durumlarının dışsal davranışsalcı yöntemle incelenemiyor oluşu mekanistik bilinç görüşlerini, bu fenomenlerin beynin çok daha temel birtakım fonksiyonlarının sonucu oluşu da düalistik bilinç görüşlerini Searle’ün bu hususa ilişkin yaklaşımının dışında bırakır. Beyinle özdeş olmayan öznel bir fenomen olarak bilincin kabul edilmesi ise bizi Searle’ün “beynin temel fonksiyonları” olarak ifade ettiği bilincin ne olduğu sorusuna cevap bulmaya zorlar. Searle’ün bilinci naturalistik perspektifte açıklamasını tutarlı bir biçimde ortaya koymanın yollarından biri de bu açıklamaya uygun bir dil görüşü geliştirmiş olmasıdır. İnsan bilincinin biricikliğinin yapay zekâ yoluyla modellenemeyeceği fikri, bilinç ile yoğun bağlantılara sahip dilin de insana özgülüğünü ima eder. Bu nedenle Searle’ün dile ve dil-bilinç ilişkisine dair yaklaşımının ortaya konulması, onun yapay zekâ kuramına karşı çıkma gerekçesini de dilin oluşumu ve karakteri çerçevesinde anlaşılır kılacaktır. Bu çalışma, Searle’ün güçlü yapay zekâ kuramını reddetmesinin temelinde varsaydığı ontolojik ayrımın esasen temelde bilincin ve dolayısıyla dilin insana özgülüğünden kaynaklandığı düşüncesinin tutarlılığını ortaya koymayı amaçlar.
The Source of Anti-Physicalist Arguments: The Unbridgeable Gap between the Phenomenal and the Physical
Authors: ARICI Murat
Published: December 2020

There is a long-term ongoing discussion on the nature of the relation between the mental and the physical. One of the chief reasons why the nature of this relation resists to a tenable solution for centuries is a compelling gap that philosophers of mind think is inevitable to face when they try to bridge between the mental and the physical. This paper raises three questions regarding the gap, which we call “the phenomenal-physical gap:” what results does this gap have against the materialist-physicalist conception of the world, why do we have this gap or why does it emerge in the first place, and can it be explained away in favor of physicalism? In attempting to answer the first question, the paper analyzes commonly known anti-physicalist arguments to point out the recalcitrant nature of mind (and phenomenality) against the materialist-physicalist conception of the world. To answer the second question, the paper makes three diagnoses and put forward three corresponding constraints that are unavoidable in any (failing) attempt to establish a metaphysical connection between the mental and the physical. Finally, in answering the third question, the paper addresses one attempt made by David Papineau, and implies that his and other similar attempts to explain away the gap in question are not likely to succeed. The ultimate assertion of the paper is that any attempt to bridge the gap between the mental and the physical is destined to fail given the constraints put forward on the phenomenal nature of mind; and thus, the best action is to pursue a more satisfactory level of understanding of the phenomenal first, by postulating new concepts, correctly categorizing those, discovering new dimensions of the phenomenality and so on.

Authors: Baker Hutaf Mustafa , Alsaoud Hussam Ahmad , Abdel-Halim Hamzeh Mohamad
Published: December 2020

A simple, sensitive and reproducible method for the determination of ranitidine hydrochloride in pharmaceutical preparations was investigated. This spectrophotometric method was based on the formation of a deep red color product with ninhydrin in basic media and the absorbance measured at λmax = 480 nm. The reaction occurs at 45 °C with pH = 10 having a contact time of 38 minutes. Under the optimum conditions, Beer’s Law is obeyed in the concentration range of 8.98×103 - 9.90×104 µg/L. The coeﬃcient of correlation was found to be 0.999 for the obtained method with molar absorptivity of 3.05×103 L/mol.cm. The calculated Sandell’s sensitivity is 0.108 μg/cm2. The limit of detection and limit of quantification are 0.0997 and 0.3023 µg/mL, respectively. The low values of the percentage relative standard deviation and percentage relative error indicate the high precision and the good accuracy of the proposed method. The stoichiometry of the reaction is determined and found to be 1:4 (Ranitidine hydrochloride:Ninhydrin). The initial rate method confirmed that this reaction is first order one.

Herein, we describe the synthesis and characterization of bis(N-(diethylcarbamothioyl)cyclohexane carboxamido)copper(II) complex, cis-[Cu(L-κ2S,O)2], has been prepared by the reaction of N-(diethyl carbamothioyl)cyclohexanecarboxamide ligand with copper(II) acetate. The green colored crystals of the complex were obtained by slow evaporation of their dichloromethane:ethanol solution (2:1, v:v). The crystal structure of cis-[Cu(L-κ2S,O)2] was obtained by single-crystal X-ray diffraction. The crystal structure reveals an monoclinic C2 (no. 5) space group with cell parameters a = 14.848(3) Å, b = 10.543(2) Å, c = 10.511(2) Å, β = 123.84(3)°, V = 1366.7(7) Å3, Z = 2, T = 153(2) K, μ(MoKα) = 0.979 mm-1, Dcalc = 1.327 g/cm3, 4979 reflections measured (6.6° ≤ 2Θ ≤ 50.68°), 2243 unique (Rint = 0.0223, Rsigma = 0.0444) which were used in all calculations. The final R1 was 0.0225 (>2sigma(I)) and wR2 was 0.0490 (all data). The angular structural index parameter, τ4, is equal to 0.40, which confirms the distorted square planar geometry for the title compound. The puckering parameters (q2 = 0.015(3) Å, q3 = 0.576(3) Å, QT = 0.577(3) Å, θ = 1.6(3)° and φ = 20(11)°) of the title complex show that the cyclohexane ring adopts a chair conformation. The two ethyl groups of the diethyl amine group have anti-orientation with respect to one another. The crystal packing shows the molecules stacked in parallel sheets along [010], accompanied by C3-H3A···O1ⁱ (i -x, +y, 1-z) intermolecular contact.

Determining the effectiveness of practicing non-pharmaceutical interventions in improving virus control in a pandemic using agent-based modelling
Authors: Buhat Christian Alvin , Villanueva Steven Kyle
Published: December 2020

In order to determine the effectiveness of non-pharmaceutical interventions on an epidemic, we develop an agent-based model that simulates the spread of an infectious disease in a small community and its emerging phenomena. We vary parameters such as initial population, initial infected, infection rate, recovery rate, death rate, and asymptomatic rates, as inputs. Our simulations show that (i) random mass testing decreases the number of deaths, infections and time duration; (ii) as well as quarantines; (iii) social distancing lengthen outbreak period to an extent and helps flatten the epidemic curve; and (iv) the most effective combination of NPIs to minimize death, infection and duration is no mass testing, no social distancing and a total lockdown. Results of this study can aid decision makers in their policies to be implemented to have an optimal output.

Severe hypophosphatemia is a rare electrolyte disturbance among surgical patients associated with severe fatigue, impaired cardiac and respiratory functions. Although mild hypophosphatemia is common after parenteral administration of intravenous iron replacement, severe hypophosphatemia is not usual in perioperative period. We present a case of 76-year-old female who underwent surgery for a left paramediastinal mass. Laboratory examination showed hypochromic microcytic anemia. A total dose of parenteral 1000 mg ferric carboxymaltose was administered two days prior to the operation with the aim of achieving a rapid increase in hemoglobin. We performed a wedge resection for the mass originating from the left upper lobe. The patient developed dyspnea and fatigue with severe hypophosphatemia on postoperative third day. The clinical status of the patient could be only improved with parenteral administration of high dose of sodium phosphate. We tried to emphasize this unexpected complication of intravenous iron replacement and the features of its management.
The Effect of Multilingualism on Cognition, Memory, and Emotions: A Review
Authors: Anastassiou Fotini
Published: December 2020

A very popular field in research on bilingualism and multilingualism is how bilingual and multilingual people perceive and express their feelings and which languages they prefer each time (Pavlenko, 2012). A fascinating issue is that of distancing oneself from an L2 - something that has also been discussed in the texts of bilingual writers who have stated that their L2 was for them a less emotionally charged language, in comparison with their L1. Besides, a speaker often uses his L1 to express emotions, since each language can convey distinct emotional meanings according to the interlocutors and the context.  Moreover, research on conscious event retrieval and autobiographical memory has also provided evidence for memory and language, as it has been found that memories tend to be more readily available for retrieval in the language in which they first appeared. Bilinguals generally report their memories in more detail and the level of processing during memory retrieval is higher in the language in which the event occurred. The exploration of the effect of multilingualism on memory and emotions is a promising field that can help educators and academics better understand the speakers’ abilities and specific attributes.

Introduction: Strangling an infant is one of the most common methods of murder. Although rare, it remains a serious condition because of its complications.

Case Report: We report a 3-month-old infant, probably strangled, who was admitted to Fann′s emergency service with altered consciousness 10 hours prior to admission. Computed tomography (CT) scan showed a range of hypodensity in the carotid territories. The victim died later of secondary complications.

Conclusion: Infant strangulation injuries are often fatal. Management must also include forensic aspects.
An Experimental Investigation of Mass Noun Types and Article Usage
Authors: Alzamil Abdulrahman
Published: December 2020

Speakers of languages with article systems have to make different article choices in the case of mass versus countable nouns. This study addressed article use with different types of mass nouns (liquid, solid and abstract). It investigated: a) whether first language (L1) Arabic speakers used English articles accurately with mass nouns; and b) whether they were sensitive to different types of mass noun.

To address these issues, the study recruited twenty-seven English as a Foreign Language (EFL) Saudi-Arabic speaking participants and five native speakers of English, who formed a control group. Members of the experimental group were proficient to the elementary level, according to the Oxford Quick Placement Test. A written forced-choice elicitation task was administered to test their article use.

The findings showed that: a) the Arabic speakers performed similarly to the native speakers of English in liquid contexts, but differently in solid and abstract contexts; b) the Arabic speakers did not perform similarly across all types of mass nouns, as they were sensitive towards mass noun types; c) their article use was more accurate in liquid contexts than in solid and abstract contexts; and d) they faced difficulties using articles with mass nouns that can be pluralised in Arabic. These findings indicate that the use of articles with mass nouns should be examined in the light of their subtypes, as well as whether second language (L2) learners’ L1 pluralise them or not.

Published: December 2020

The polysaccharides isolated from Polygonatum odoratum (Mill.) Druce (POPs) by water extraction, after precipitation with ethanol were purified through deproteinization, decolorization, dialysis, and column chromatography leading to a purified polysaccharide (POPs-I) content of 90.7 %. The scavenging of oxygen free radicals and inhibition of lipid peroxidation (LPO) by POPs-I were analyzed using a colorimetric method. The results showed that the hydroxyl radical scavenging ability of the polysaccharides was weaker than that of benzoic acid, but stronger than those of ascorbic acid and mannitol, and that the superoxide anion radical scavenging ability was inferior to those of all three. When the concentration was higher than 1.0 mg/mL, the POPs-I could inhibit LPO by superoxide anion radicals to a certain degree. Therefore, this work suggests that POPs-I are potential antioxidant agents in medicine and functional food.

Authors: Jha Prakash Kumar , Jha Vinay Kumar
Published: December 2020

Spinach leaves powder was modified by activation with conc. H2SO4 and was characterized by using FTIR, optical microscopy, XRD analysis and methylene blue adsorption method. The maximum specific surface area measured by the Methylene blue adsorption method was 499 m2/g. The adsorption of iodine was investigated by varying parameters as pH, adsorbent dose, contact time and I2 concentration. The adsorption process was fitted to the Langmuir model controlled by pseudo - second –  order kinetics with a constant rate value of 0.00305 g/(mg·min). The maximum adsorption was at pH 10. The maximum adsorption capacity was 909.091 mg/g. The ∆G value was -25 kJ/mole, which confirmed the physico - chemcal adsorption process.

Published: December 2020

Games User Research (GUR) is an interdisciplinary field of study that aims to measure, analyze, and understand the interaction and experience of players with digital games. Joining efforts to the advances in GUR, this work focuses on the evaluation of player interaction with Location-Based Games (LBGs), seeking to understand which aspects of this interaction can be explored through interviews and how researchers and practitioners have been using this method. We analyzed 23 studies that applied interviews to this end and conducted an expert opinion survey with the authors of these studies. As a result, we presented lessons and research challenges for the use of interviews in this type of evaluation, in hopes to encourage the conscious and systematic application of this method, in addition to guiding practitioners and researchers, especially beginners.

Published: December 2020

Designing games to encourage players' positive and healthy behaviors is both a necessity and a challenge. Although the game research field has relevant contributions in literature, especially regarding gamification, serious games and persuasive computing, when the application domain is critical, such as education or health, it is necessary to understand the context in which a game will be inserted before actually proposing and designing it. This paper presents a collaborative workshop for problem understanding and requirements elicitation in the early stages of game design. The workshop stresses the importance of problem-understanding from a sociotechnical perspective before developing a game and before directly engaging other stakeholders. The paper presents the workshop in practice where designers must understand how to support children to perform speech therapy exercises outside hospital settings. The workshop was conducted to produce a systemic understanding of the problem domain, of human and technical aspects, possible solutions and their implications to be used as inputs for game design and evaluation. The paper presents the workshop and its main results, discussing lessons learned and highlighting the need for early and lean practices to promote the socially aware design of games.

Authors: Ribas Lucian Rossoni , Gomes-Jr Luiz , Silva Thiago H.
Published: December 2020

The spread of misinformation, hate speech, or sexist discourse had become a significant problem, especially on chat platforms. This article describes a data collection and processing tool to support research on users’ behavior exposed to these contents. Our motivation is the recent need to study profiles that propagate this type of information and the need to understand these new dissemination mechanisms. This tool provides a web configuration panel and a mobile application for data collection. Using a chatbot mechanism, the panel allows researchers to perform personalized experiments to analyze specific issues. The application collects the user’s basic profile, allows interaction with the chatbots sent by the researcher, and runs on the volunteers’ devices, similar to a real messaging application such as WhatsApp or Telegram. The data generated regarding the user’s interactions with the application can be exported for analysis through the panel. Also, we describe the insertion of optional codes that can be executed in parallel to the conversations, helping in sophisticated personalizations. We believe that the proposed open-source tool will help researchers from different areas, even without computer programming skills, to understand fundamental mechanisms of user behavior in mobile chat systems.

Published: December 2020

In this work, we present the platform Boca a Boca Virtual, a kind of virtual catalog that aims to help self-employed professionals and small businesses to start their presence in the digital environment, promoting their services and products in a simple and fast way. The idea emerged during the beginning of the COVID-19 pandemic, especially with social isolation, whose concern, from an economic and social point of view, was to allow autonomous service providers and establishments, in general, to continue offering their products and/or services. Through the platform, a consumer can search for a specific product and service within his own neighborhood and city, strengthening the local economy. In addition, Boca a Boca Virtual is integrated with Google Maps, in such a way that registered developments are also indexed by the Google search engine, improving their visibility and potentially increasing more customers. The platform is fully responsive, combining several recent web development technologies. Today it has more than 140 registered enterprises, from more than 30 Brazilian cities.
