Investigation of Scale-Dependent Groundwater/Surface-water Exchange in Rivers by Gradient Self-Potential Logging: Numerical Modeling and Field Experiments
Authors: Ikard Scott J. , Briggs Martin A. , Lane John W.
Published: July 2021

Exchanges of groundwater and surface-water are fundamental to a wide range of water-supply and water-quality management issues but challenging to map beyond the reach scale. Waterborne gradient self-potential (SP) measurements are directly sensitive to water flow through riverbed sediments and can be used to infer exchange locations, direction (gain versus loss), scale, and relative changes, but to date applications to river corridor hydrology are limited. Numerical modeling and field experiments were therefore performed herein, each emphasizing waterborne gradient SP logging for identifying and locating focused vertical groundwater discharge (surface-water gain) and recharge (surface-water loss) in a river. Two and three-dimensional numerical models were constructed to simulate the polarities, appearances, and peak amplitudes of streaming-potential and electric-field anomalies on a riverbed and in the surface-water that were attributable to steady-state vertical fluxes of groundwater through high-permeability conduits in the riverbed. Effects of varied hydraulic length-scale of exchange and surface-water depth were tested through numerical modeling. Modeling results aided in data acquisition and interpretation for three repeated field experiments performed along a 1.5–2.0 km reach of the Quashnet River in Cape Cod, Massachusetts, where focused, meter-scale groundwater discharges occur at discrete locations within otherwise ubiquitous and more diffuse groundwater upwelling conditions. Strong gradient SP anomalies were repeatedly measured in the Quashnet River at previously confirmed locations of focused groundwater discharge, showing the efficacy of waterborne gradient SP logging in identifying and characterizing groundwater/surface water exchange dynamics at multiple river network scales.

Published: July 2021

Leakage of reservoirs will not only lead to the waste of water resources, but also cause soil salinization, dam break, and other serious consequences. Leakages may still occur even anti-seepage engineering measures are taken. This study utilized continuous waterborne electrical resistivity tomography to localize potential bottom geomembrane leakage areas in Datun plain reservoir in the east route of South-to-North Water Diversion project. The integrated sensitivity was firstly evaluated to select the optimum electrode array. Four leakage scenarios were numerically simulated and the resulting resistivity distribution patterns were further categorized to identify leakage locations. A total of 33 field survey lines were measured using floating cables over 5 km2 water surface. Robust inversion method was adopted for delineation of geomembrane interface. In the end, we found most of the soil surfaces are still kept under original flat conditions. Based on the abrupt decrease of resistivity from over 120 Ω·m to 80 Ω·m or lower values, two specific sites under the geomembrane with an area of 0.31 km2 potential leakage areas were localized. Even though there are no clearly leakage signs observed from the reservoir water surface, these resistivity results provide important preliminary data to further narrow down the leakage locations.

This study aimed to estimate the association of P2O5 doses with and without rhizobia inoculation to maximize the agronomic performance and yield of cowpea on an Oxisol in the Cerrado region of Tocantins. The experiments were carried out in two periods during the 2014/2015 growing season at the Experimental Farm of Gurupi belonging to the Federal University of Tocantins, using the variety BRS Novaera. Inoculation was carried out with a standard strain recommended for cowpea. The experimental designs were randomized in blocks in a 2×6 factorial arrangement, with the first factor consisting of the inoculation (presence and absence) and the second factor consisting of six phosphorus doses (0, 30, 60, 90, 120, and 150 kg ha−1 of P2O5), totaling 12 treatments with four replications. Total chlorophyll, leaf P content, flowering, hundred-grain weight, and yield were evaluated. Phosphorus fertilization had a positive influence on the total chlorophyll, flowering, and leaf P content of cowpea on the Oxisol in the Cerrado region of Tocantins. The application of 113.42 kg ha−1 of P2O5 provided a yield of 1,124 kg ha−1 in the first planting period, corresponding to an 83% increase. However, phosphorus fertilization and inoculation increased grain yield in the second period, with the maximum yield reaching 145.94 kg ha−1, obtained with the maximum effect dose of 123.04 kg ha−1 of P2O5, with a yield gain of 257.3%.

Heterogeneous effects of agricultural technical assistance in Colombia
Authors: Torres Franco Nicolás Arturo , Dávalos Eleonora , Morales Leonardo Fabio
Published: July 2021

Small family farms account for 72 percent of the farms in the world. Most of these farms, in developing countries, face labor productivity gaps. One of the strategies to increase agricultural productivity focuses on implementing technical assistance programs. Using agriculture microdata, we estimate the marginal treatment effect of receiving technical assistance services. We find that technical assistance generates heterogeneous effects. On average, agricultural units receiving technical assistance increased their agricultural production by 50.4 percent. However, there is important heterogeneity of technical assistance’s effects across the production units’ unobserved and observed characteristics.

Authors: Lara Caique , Villamil Julie , Abrahao Anthony , Aravelli Aparna , Daldegan Guilherme , Sarker Sharif , Martinez Daniel , McDaniel Dwayne
Published: July 2021

Fossil fuel power plants are complex systems containing multiple components that require periodic health monitoring. Failures in these systems can lead to increased downtime for the plant, reduction of power, and significant cost for repairs. Inspections of the plant’s superheater tubes are typically manual, laborious, and extremely time-consuming. This is due to their small diameter size (between 1.3 and 7.6 cm) and the coiled structure of the tubing. In addition, the tubes are often stacked close to each other, limiting access for external inspection. This paper presents the development and testing of an electrically powered pipe crawler that can navigate inside 5 cm diameter tubes and provide an assessment of their health. The crawler utilizes peristaltic motion within the tubes via interconnected modules for gripping and extending. The modular nature of the system allows it to traverse through straight sections and multiple 90° and 180° bends. Additional modules in the system include an ultrasonic sensor for tube thickness measurements, as well as environmental sensors, a light detecting and ranging (LiDAR) sensor, and camera. These modules utilize a gear system that allows for 360° rotation and provides a means to inspect the entire internal circumference of the tubes.

A Review on Forecasting Agricultural Demand and Supply with Crop Price Estimation Using Machine Learning Methodologies
Authors: Mahore Pallavi Shankarrao , Bardekar Dr.Aashish A.
Published: July 2021

Agriculture plays a vital role in Indian economy. It contributes 18% of total India’s GDP. In India, most of the crops are solely dependent upon weather conditions. Hence, more yield of crops can be achieved by analyzing agro-climate data using machine learning techniques. Machine learning (ML) is a crucial perspective for acquiring real-world and operative solution for crop yield issue. From a given set of predictors, ML can predict a target/outcome by using Supervised Learning. To get the desired outputs need to generate a suitable function by set of some variables which will map the input variable to the aim output. Crop yield prediction incorporates forecasting the yield of the crop from past historical data which includes factors such as temperature, humidity, ph, rainfall, crop name. It gives us an idea for the finest predicted crop which will be cultivate in the field weather conditions. These predictions can be done by a machine learning algorithm called Random Forest. It will attain the crop prediction with best accurate value. The algorithm random forest is used to give the best crop yield model by considering least number of models. It is very useful to predict the yield of the crop in agriculture sector.

In today's world fuel demand is increasing day by day. Liquefied Petroleum Gas (LPG) is the most used fuel in Kitchen. This is filled in a cylinder in liquid state. These cylinders blast sometimes, the main reason of cylinder blast is gas leakage. So, to avoid this we need to detect the leakage of gas. For this we need an automatic gas leakage detection system which detects leakage of gas and gives alerts. This type of automatic security system can save people from dangerous blasts and prevent accidents. Nowadays IOT (Internet of Things) is widely used in day-to-day life. There are many home appliances which are based on IOT thus it becomes easier to manipulate them. As we know the kitchen is the most important part of our home, but we also heard about the disasters happening in the kitchen due to various reasons and many people lost their lives. There might be various reasons behind the cause of these disasters but the main and mostly happens is due to the leakage of LPG gas from the cylinder. As LPG gas is highly inflammable gas, a small leakage of gas can be costly for human life. So, if we can detect these leakages of gas before it causes any serious issue then we might save many lives.

Authors: Nath Ranajit , Roy Ratna , bhattacharyya Soubhik , Datta Sourav
Published: July 2021

In the past, few decades cancer has become a worldwide problem to mankind. Lung cancer is the most life-threatening among all cancer types. Non-small cell lung cancer (NSCLC) is the main reason for approximately 80% to 90% of deaths. Lack of early detection and incompetent conventional therapies is the leading cause for poor prognosis and overall survival rate of lung cancer patients. Immense progress in the field of nanotechnology and nanomedicine has given inspiration to the development of an alternative strategy in the treatment of lung cancer. The unique physicochemical properties of the nanoparticles likeability to cross the different biological barriers, effectiveness in delivering hydrophobic drugs which are difficult to incorporate in the body, and targeting in the particular disease sites have given rise to enormous advantages for nanoparticulate systems for the early diagnosis and active delivery of drugs for a better treatment for lung cancer. Recently, many formulations of nanocarriers like lipid-based, polymeric and branched polymeric, metal-based, magnetic, and mesoporous silica are being used in this treatment. Innovative strategies have been employed to utilize the multicomponent, three-dimensional structure of nanoparticles and modify it and construct a new structure moiety that has multifunctional capabilities. Developing such designs permits simultaneous drug delivery of chemotherapeutics as well as anticancer gene therapies to site-specific targets. In lung cancer, nanoparticle-based therapeutics is now breaking the ground in the diagnosis, imaging, screening, and treatment of primary and metastatic tumors. This review emphasizes the pathogenesis of lung cancer and its treatment by nanotechnology.

Published: July 2021

The paper is regarding the automating of driver’s license testing system and updating the results to the person through website and conjointly through registered email. Usually, while driving test the person who requested for license have to be compelled to show his driving skills ahead of the authorities. The person need to operate the vehicle according to several rules. If he fails, he/she are knocked out and have to appear for the driving test next time. The Officials observe mistakes of the applicant physically. The proposed solution for the automation of existing manual test method permits the elimination of intervention of humans and improves the accuracy of driving test thereby going paperless, with Driving Skill Evaluation System. In the proposed system, we have a tendency of taking data from sensor as inputs from hardware simulator and stores into the database. In this system, the person participating in the test are obsereved by sensors. Therefore weather the person is qualified or not is informed to the applicant as well as the authorities.
Gradual increase in number of road hazards are due to less practice in driving and illegal driving license given to the unskilled drivers by taking bribe. To beat this drawback, automated driving license test will be advantageous. This solution is introduced for ensuring the quality in approving in license to enhance safety.

Liquid spawn, an important technical support for industrial production of edible fungi, has some advantages, such as fast growth, strong activity, uniform quality and easy inoculation. However，the study of the fermentation parameters of Pleurotus eryngii liquid spawn is less, which cannot effectively guide the production practice. Therefore, in order to provide a theoretical basis for the production of liquid spawn and industrial production of Pleurotus eryngii, response surface analysis was used to optimize the liquid spawn formula and conditions. The best carbon and nitrogen source of liquid medium was glucose and yeast extract, respectively. The optimum formula of medium was obtained by response surface analysis. Combined with the practical operation, the formula was modified to 29.00 g/L glucose, 2.90g/L yeast extract, 0.90g/L KH2PO4 and 1.00g/L MgSO4. The effects of various factors on the dry weight of mycelia were analyzed, the results indicated that the influence follow the sequence: glucose, KH2PO4, yeast extract and MgSO4, among them, the first two factors had significant effect. The interaction between glucose and KH2PO4 had obviously effects on the dry weight of mycelia. The interaction between glucose and yeast extract had a certain effect. The optimum culture conditions of liquid spawn were obtained by response surface analysis. Combined with the actual situation, the conditions were modified to liquid volume 106.00mL/250mL, rotating speed 165.00r/min, temperature 23.60℃, initial pH 6.70. The effects of various factors on the dry weight of mycelia was analyzed, the results indicated that the influence follow the sequence: initial pH, liquid volume, temperature and rotating speed, among them, the first three factors had extremely significant effect. The interaction of liquid volume and rotating speed, temperature and initial pH had obviously effects on mycelial dry weight.

This paper examines specifically the phenomena leading up to the 2019 general elections in Wonosobo, Central Java. Using the case study method by emphasizing the primary source of the interview results, this research confirms the existance of money politics. As is generally the case in other regions in Indonesia, transactional politics also become parts of the celebaration of democracy in Wonosobo.

Authors:   Redazione
Published: July 2021

Il presente lavoro pone in rilievo i drammatici effetti della pandemia da Covid e del conseguente lockdown per molte famiglie straniere e per i loro figli. In particolare, si vogliono evidenziare le problematiche economiche, sociali e scolastiche riscontrate da queste famiglie e dai loro figli nell'attuale lungo periodo di crisi sanitaria e di chiusura delle scuole. Tanti alunni stranieri non hanno potuto accedere alla didattica a distanza e in questi mesi non hanno avuto rapporti con gli insegnanti e con i compagni di classe, rimanendo completamente fuori dal circuito scolastico e da tutte quelle occasioni di interazione e di apprendimento fondamentali per il loro percorso formativo.

The global pandemic caused by the COVID-19 has profoundly changed the daily life of most of the world population. People with disabilities have been particularly affected by these changes, which often have accentuated their isolation and marginalization also due to greater difficulties in accessing healthcare services. People with disabilities have also been impacted in relation to their ability to participate in physical activity with even more adverse consequences for their quality of life and health. The aim of this study was to explore the impact of the COVID-19 pandemic on physical activity practice of people with disabilities and to understand the changes that caregivers have perceived for the participation in physical activity of this specific population. It emerged that, regardless of the type of disability, people with this condition experienced drastic reductions in their physical activity levels during the pandemic and in most cases did not have access to any type of remote guidance. Furthermore, a higher prevalence of sedentary behavior and negative changes in eating habits have been reported by the caregivers, highlighting the need for specific strategies and initiatives for people with disabilities to maintain healthy habits and a physically active lifestyle.

Published: July 2021

Over the past decade the growing number of students with Attention and Learning Disorders in universities has been documented all over the world. Difficulties experienced by students during their academic career have led to an increase in the support services offered by Universities to meet their needs. This development has taken place as a result of changing attitudes and instructional practices across many countries. In this paper, we highlight an example from the Unites States where one university provides multiple services to increase optimal outcomes for this specific population.
Videovalutare l'agire competente dello studente
Authors: Perla Loredana , Vinci Viviana
Published: July 2021

La videoanalisi è un oggetto di studio che vanta una consolidata tradizione. Pratica multimetodologica e area di studio interdisciplinare, essa risponde a numerosi problemi conoscitivi posti dalla complessità dei fenomeni didattici da indagare e propone strumenti e tecnologie che hanno un potenziale di descrizione, riproduzione e comprensione dei fenomeni molto alto. L'analisi video di un compito autentico costituisce un dispositivo di "supporto" per realizzare la valutazione dell'agire competente dello studente: un prototipo in grado di supportare la focalizzazione delle azioni che strutturano la competenza da valutare, per identificarne dimensioni, indicatori e livelli. Si descrive un percorso di ricerca-formazione che ha coinvolto 30 insegnanti di 11 Istituti scolastici della regione Puglia. Esito del progetto la descrizione del prototipo di videovalutazione che supporta gli insegnanti nella costruzione della rubrica valutativa e l'espressione del giudizio finale per livelli. L'attività riflessiva sollecitata nelle docenti, attraverso l'uso del dispositivo proposto, ha avuto l'obiettivo di accompagnare gli insegnanti a riconsiderare criticamente il proprio l'agire, sollecitando lo sviluppo e il consolidamento della propria professionalità. La ricerca ha consentito di promuovere negli insegnanti un habitus di riflessione sul proprio "fare scuola" e sulle proprie strategie valutative, sul modo in cui si gestisce la mediazione tra soggetti in apprendimento, contenuti disciplinari, metodologie, strategie e dispositivi adottati.
La grande crisi globale: una sfida per la politica industriale e per le imprese
Authors: Varaldo Riccardo , Lamberti Lucio
Published: July 2021

- The years to come are going to be very complex for global economies, a true challenge for industrial policy and corporate decisions. The first priority has been to ensure financial stability and to mitigate the credit crunch effects on economies, but a new strategic issue has to be put rapidly in place: the public rescue policy for economies and corporates. All measures must be taken to avoid the disruption of societies and economies, and this effort needs to be coordinated at the European and international level. In the short term, Italian industries will be less affected due to a higher flexibility and a less procyclical banking effect, but they will be very vulnerable in the long run because of the fragility of the corporate structure. More than other countries, Italy needs rapid action and a strategic political approach. Research and innovation are a must, and universities have to play a leading role in this phase.

A world in transition: convergence, interoperability, production processes and economic models in the media
Authors: Massarenti Cesare A.
Published: July 2021

- During the past thirty years, the transition to digital has changed both the way the media and communication industry creates and provides content and the way end users access information and interact with it. The entire organization of content production, processing and distribution is undergoing major changes and workflow is being redesigned with the use of sophisticated database technologies, allowing for the development of a new multi-channel content delivery and multiple revenue streams paradigm. The spread of interactive functionalities, the widening variety of access devices, the emergence of social networks and the progressive approach to the semantic web are redefining the relationships between traditional content providers in the media and audiences, whereby a "reader" can become an "author". Content can be accessed by means of many complementary devices, in a personalized time and space frame. Issues of convergence and interoperability, together with issues concerning intellectual property and copyright, are underlying the development of novel narrative structures and modes of content fruition. .

Concorrenza e regolazione nel settore ferroviario: l'importanza del materiale rotabile
Authors: Cambini Carlo
Published: July 2021

- The liberalization process in the railway industry is highly influenced by the availability of rolling stocks. Although these assets are duplicable and cannot therefore be defined as essential facilities, evidence from many countries shows that they represent the most relevant barrier to entry in the market. In this paper, following the UK experience, we analyse the role of the rolling stocks and the hypothesis of a vertical separation of these assets from the present owner, i.e. the incumbent operator Trenitalia SpA. We therefore evaluate the pros and cons of a potential de-integration of the Italian railway industry in order to enhance market competitiveness and the overall efficiency of this industry. .
