  • A Non-Formal Education Approach of Medicinal Plant sellers   Order a copy of this article
    by Busisiwe Ndawonde 
    Abstract: The article reports on the results of a non-formal education intervention programme that involved medicinal plant sellers in northern KwaZulu-Natal, South Africa. The study was done in two phases. The study identified and explored the prevalent challenges of the medicinal plant selling businesses. A selected number of medicinal plant sellers was exposed to a capacity building instructional intervention strategy aimed at addressing the skills and knowledge gaps identified. The principles of Education for Sustainable Development (ESD) were followed as part of the studys theoretical foundation. Data were collected through semi-structured and focus group interviews. The results reveal that the medicinal plant sellers face a number of in-processing methods and techniques, and packaging, and lack business acumen. They have, for example, poor marketing and pricing skills, low banking esteem and poor record keeping, particularly of stock. This indicates their slow implementation and application of the information and skills as discussed in previous workshops. Positively, there is evidence that some of the medicinal plant sellers had begun revisiting their business practices based on previous discussions. Overall, the processing of medicinal plant materials and packaging need urgent attention.

  • Innovative method for linking anthropization process to vulnerability   Order a copy of this article
    by Alessandra Capolupo, Lorenzo Boccia 
    Abstract: Coastal areas have been gradually modified by humans in order to face emerging social needs. This phenomenon can be traced in the Amalfi Coast (Southern Italy) through the presence of terraces, constructed to make its steep slope habitable and arable, and the construction of new buildings. The current research is aimed to investigate geomorphological and volumetric changes of the Amalfi Coast, in order to detect the anthropization process in Minori, the most ancient municipality in the Amalfi Coast, and to identify the most vulnerable areas where debris flows. Debris flow, triggered by catastrophic rainfall, is recognized as the most dangerous natural hazard for terraced landscapes. Two photogrammetric datasets, acquired in 1956 and 2017, respectively, have been analyzed to generate two fine resolution Digital Elevation Models (DEMs); orthophotos were subsequently compared and applied to calculate the Normalized Remaining Vegetation Index (NRVI) and the Digital Elevation Model of Differences (DODs). These two indices have allowed us to quantify the anthropization process suffered by the area of interest between 1956 and 2017. The two orthophotos were also classified by applying the OBIA approach for extracting a binary map: terraced versus non-terraced areas. A new Vulnerability Expeditious Index (EVI) was calculated. The comparison of those maps shows an increase of 800% of man-made infrastructures, while the extension and the location of terraces have not been subjected to any transformation. The EVI index represents a strong increment of vulnerability in the Minori municipality. The proposed method looks promising for analyzing the anthropization process and for linking it to the vulnerability of the study area.
    Keywords: anthropization process analysis; vulnerability; OBIA classification; terraces debris flow.

  • A Review Article Vermibiotechnology and Waste Management   Order a copy of this article
    by Keshav Singh, Deepak Kumar Bhartiya 
    Abstract: Abundant use of chemical fertilizers disturbs the soil texture and physicochemical properties of soil and affects the human health as well as environment. The use of chemical fertilizers has posed a serious threat to the environment and caused destruction of useful microorganisms, insects and worms in soil. The biological wastes caused environmental hazards and various adverse effects on human health and their domesticated animals, if their proper management and disposal practices are not available. Organic farming through vermibiotechnology is a better option for management of wastes by the earthworms and improvement of soil quality. It is one of the interesting aspects, since it contributes to a broad relationship among food, environmental quality and safety of human and animal health. Vermicomposting is an easy and effective way to recycling of biological wastes through vermic-activity. During this process important plant nutrients such as nitrogen, phosphorus potassium, calcium etc. are present in feed materials converted in to more absorbable form for plant. Vermicompost has not only plant nutrients but also growth regulators, beneficial bacterial and actinomycetes population with large number of worms eggs. It increases the porosity aeration, drainage water holding capacity, which reduces the irrigation water requirement for crops. It improves nutrients availability and could act as complex fertilizer granules and evolves great reduction in the population of harmful pathogenic microorganisms. Vermicompost of wastes is easily pre-parable, biodegradable, most effective, easily transportable, non-hazardous to animal, human and environment and eco-friendly which is boon for the farmers. So, we can say that the vermibiotechnology is a suitable way for sustainable development and now today need of uses of biofertilizers in crop fields.

  • Sustainable management approaches for underground heritage structures threatened by the environment and the human presence   Order a copy of this article
    by Vasiliki Kyriakou, Vassilios Panoskaltsis 
    Abstract: Cultural heritage can be considered as a "non-renewable resource of values" for humanity. Aiming at protecting and safeguarding this resource for future generations, the concept of sustainability should be applied in the management of monuments and historical sites, considering that the preservation of cultural heritage is one of the crucial topics of the Unesco Sustainable Development Goals. This paper studies the Macedonian tombs in northern Greece. Macedonian tombs are monuments of great historic importance and precious educational value, with strong particularities in their hygrothermal status. Systematic monitoring and evaluation of the indoor climatic conditions has shown that the deterioration processes are mainly caused by cyclical changes in temperature and relative humidity when the monuments are exposed to the environment and the presence of visitors. Protection against future deterioration can only be assured through proper interventions to stabilize the indoor microclimate. The purpose of this paper is to show that prior to the final decision-making, it is very important to acquire data with systematic recordings in situ, analyze them and get metadata. Recordings are used as an input in a simulation tool in order to export numerical data and diagrams as an output. This output is used in order that the right decisions are made regarding the monuments preservation. The paper concludes with recommendations for optimal preservation, based on the principles of sustainability. It should be emphasized that the proposed methodology can be applied to all Macedonian tombs.
    Keywords: heritage structures; Macedonian tombs; microclimate; hygrothermal performance; numerical simulation; sustainable management; SDG11.

    Abstract: Web Applications are extensively used all over the world-wide net. These are the applications that have made our regular day to day existence easy and straightforward. We share incredibly confidential information over the web and keeping the information confidential is the most important priority of these web-based applications. These web-based applications are vulnerable to different attacks, XSS and SQL Injection being one of the most perceived attacks. Attackers inject malicious code into the web application and can cause cataclysmic harm to the person without his/her consent. Cross Site Scripting (XSS) and SQL Injection strikes are the most generally perceived sort of attacks that a web application experience. The XSS attack is caused by executing malicious code to a web browser which runs in the server about which the user isnt aware of and is capable of catastrophic disaster. Recognizing a script that is malicious or benign can keep an unwanted attack from happening and can help the web application from keeping the data of the users confidential. The work accentuates on a portion of the conceptual approaches to identify the XSS Script on the customer side dependent on a portion of the highlights extracted from the vindictive contents.

    Abstract: rnrnHigh speed analog to digital converters (ADC) are comprehensively used in several physical structures going from correspondence systems to nuclear instrumentation. Time Interleaved Analog to Digital Converters (TIADC) are utilized to recognize higher breaking down rate structures. We consider TIADC structure with respect to Time of Flight Mass Spectrometry (ToF-MS) which require higher assessing rate to perceive the mixture creation in a precedent analyte. TIADC systems have some basic scatter botches: offset, increment and timing puzzles. Of the three jumble botches time skew is a primary thought ruining the system execution and is a strong limit of data banner repeat. Concerning ToF-MS time skew defiles the objectives and settling power. Diminishing time skew can be improves the ToF-MS execution. This paper tells about the diverse disclosure and correction part of time skew. Three sorts of confound review systems are open: Analog, Digital Background and Digital Foreground. Simple strategy supplements the time estimation module of ToF-MS with simple hardware to address mistakes. In any case, this has some intrinsic simple issues like commotion, impedance and is slower contrasted with advanced circuits. Foundation mistake revision strategies utilize a few procedures. Advanced channel and channel bank strategies add to circuit multifaceted nature are computationally serious and face combination issues. Measurements put together adjustment techniques depend on the insights of the info flag. Dazzle computerized foundation strategies force extra imperatives toward the front like a wide sense stationary (WSS) band constrained info flag and the requirement for oversampling. Accordingly, their adequacy depends incredibly on the measurements of the information flag. Advanced forefront immaculate remaking technique utilizes a pilot tone to identify and address blunders. This technique is relevant just to limit data transmission signals.

  • A NOVEL THREE LEVEL INTEGRATED AC-DC CONVERTER FOR RENEWABLE ENERGY SOURCE   Order a copy of this article
    by A.Santhi Mary Antony 
    Abstract: Power stability is an important fact for the development of power. This power stability is maintained when voltage and current are in phase with each other. More harmonics are generated led to poor output voltage regulation and power factor is reduced. An effective way to achieve power factor correction is attained by power stability analysis. A Single stage PFC three level converter is proposed by using renewable energy as an input. The proposed converter integrates an AC-DC boost PFC converter into three level dc-dc converter. A flexible DC link voltage is used to achieve power factor correction at high line voltage. The power factor is improved and output voltage regulation is increased. An enhancement of load efficiency of the converter is obtained by less number of switches. The converter operation is explained and simulated by using renewable energy source as an input. The implementation of hardware is done for PV system and results are determined.

    by S.Prabha Kumaresan, Chee Keong Tan, Ching Kwang Lee, Yin Hoe Ng 
    Abstract: Non-orthogonal multiple access (NOMA) has been envisioned as a fundamental method towards fifth generation (5G) cellular networks. Typical clustering schemes employ adaptive user clustering (AUC) to improve the performance of the NOMA system using brute-force search (BF-S). But, the search to perform AUC is computationally complex and practically infeasible. Therefore, AUC using particle swarm optimisation (PSO) algorithm is proposed to minimise the computational complexity. PSO is an intellectual algorithm, implements using a random number of particles moving in a search space. The particles are evaluated by the fitness value on each iteration until it reaches the optimal solution. Simulation results demonstrate that NOMA system employing PSO-based AUC is able to reduce the complexity with acceptable throughput performance compared with BF-S-based AUC. Furthermore, it is noteworthy that the proposed PSO-based AUC outperforms the conventional clustering with fixed number of users in NOMA system and orthogonal multiple access (OMA) system in terms of throughput performance.
    Keywords: non-orthogonal multiple access; NOMA; adaptive user clustering; AUC; particle swarm optimisation; PSO; throughput maximisation; low complexity.

    by Krishnakumar Krishnasamy, Arockia Selvakumar Arockia Doss 
    Abstract: A study on failure analysis of forged link chains used in a cement plant for scraper application is presented. The forged steel linkages are generally subjected to cyclic loading in abrasive environments. Fractured components were fabricated by forged 20MnCr5 structural steel and case hardened. The fractured samples were initially subjected to visual and stereo-binocular observations. The scanning electron microscope (SEM) was used to examine fractured surface. It was observed that the major cause of the chain failure was due to wear the reduction of case depth at the outer surface was worn out in abrasive environment. The novel idea in the proposed work is selection of material and choosing the proper heat treatment process to improve the tensile strength of forged link. By analytical approach EN30B steel is proposed with through hardening process. In experimental tensile test validation, 16% of average tensile strength is enhanced in proposed EN30B steel compared to existing 20MnCr5 steel.

  • Analysis of wastewater from medical institutions in India   Order a copy of this article
    by Aastha Dhingra, Nadeem A Khan, Sirajuddin Ahmed, Viola Vambol, Svitlana Kovalenko 
    Abstract: One of the main reasons for the deterioration of the quality of natural waters is industrial and household human activity. Medical wastewaters contain significant amounts of chemical waste, such as antibiotics, disinfectants and others. Wastewater from health-care facilities contains organic particles (faeces, hair, food, vomit, paper, fibres), soluble organic material (urea, proteins, pharmaceuticals), inorganic particles (sand, grit, metal particles), soluble inorganic material (ammonia, cyanide, hydrogen sulfide, thiosulfates) etc. The problem is intense as these get discharged into the ground and surface water, due to improper treatment before being discharged as part of the hospital effluents. In some countries, such as India and Ukraine, hospital wastewater is discharged to urban wastewater treatment plants. The quantity of wastewater produced in a health-care facility depends on the amount of water used and is best measured by the water consumption. A survey was conducted in 75 hospitals, including 25 hospitals from the categories of high, medium and low. The average water consumption per bed per day in a hospital of Delhi ranges between 500-600 LPD. The annual water consumption in hospitals of Delhi is about 9000 million litres. Since the composition of the wastewater of medical institutions is diverse, it is necessary to conduct an extensive characterization to study the composition of the wastewater for their further use.
