Authors: Chavan Kalidas D. , Giri Purushottam A. , Mumbre Sachin S. , Bangal Rajendra S.
Published: July 2019

Background: The mutual trust between doctor and patient, an indispensable part of the healthcare, is weakening day by day. This has resulted in unwanted incidences of violence and attacks on doctors. Communication between doctors and patients is an integral part of the relationship and is one of the major determinants of mutual trust. Apart from the knowledge and skills required to treat a disease, communication skill is an indispensable part of a doctor’s professional life. The resident doctors do not get a chance to learn and implement the communication skills required for the doctor patient relationship.Methods: An interventional study was carried out amongst 377 resident doctors of first to third year, from randomly selected medical colleges of Maharashtra having postgraduate courses in clinical subjects and affiliated to Maharashtra University of Medical Sciences, Nashik, Maharashtra during the period of February 2017 to January 2019.Results: There was significant difference in the pre and post test scores for quantified knowledge in relation to training in communication skills (p<0.0001), and also significant difference in the pre and post test scores for quantified knowledge in relation to basic doctor patient relationship, suggesting that the intervention was effective in improving the communication skills.Conclusions: The study has shown that there was significant difference in the pre and post test scores for quantified knowledge in relation to being doctor, basics of communication skills, doctor patient relationship, communication in special situation, and training in communication skills.

Published: July 2019

Crime is a man-made concept. Crime and its relation to various socio-demographic factors has been subject of debate since time immemorial. Crime is wide spread, diverse in nature and increasing in frequency. The rate of crime is steadily increasing day by day all over the world, India being no exception.Crime and its relation to various socio demographic and economic factors determine the nature of crime. In the age old times punishment was harsh and cruel; the punishments were exiling, enslaving, torturing, mutilating, and execution. The jails, lockups, and detention centres of various kinds have been in existence for thousands of years. But, only 200 years ago these places were used for detention for offenders. Various articles and studies had been reviewed in this study to gain the knowledge about the general health and mental health about the prisoners. The mental and general health problems among the inmates were highly prevalent when compared to general population.

Published: July 2019

Background: Chronic rhinosinusitis (CRS) is one of the most common health problems which incurs significant medical costs and has severe impact on lower airway diseases and general health of the patient. The aim of this study was to describe the demographic and clinical profile of chronic rhinosinusitis patients.

Methods: In this study 94 patients were included. After taking a brief history, their clinical symptoms were assessed using SNSG test (sino nasal symptom grading test). The findings were further confirmed by diagnostic nasal endoscopy.  

Results: We found that maximum number of patients were in the age group of 18-27 years with a slight male preponderance. Also rural population had more cases of CRS with nasal discharge being the commonest complaint at the time of presentation. After diagnostic nasal endoscopy (DNE) it was found that ethmoidal polyps are more common in CRS patients however more number of CRS patients presented without polyps.

Conclusions: We conclude that chronic rhinosinusitis manifests more in male and rural population with nasal discharge and ethomoidal polyps being the most common presentation. The subjective assessment of clinical symptoms could be done by SNSG test; however it further requires detailed studies.

Authors: Tegginamath Akshay , Patil Channabasava
Published: July 2019

Background: In developing countries like India the need for cost conscious medical practice has a major role in the economy of the country. The extensive use of costly investigative modalities puts huge burden on the patient needing proper medical care. This study is undertaken to assess the role of different diagnostic tools like clinical diagnosis, magnetic resonance imaging (MRI) and arthroscopy in diagnosis of meniscal tears.

Methods: A prospective study was conducted among 90 individuals with knee injuries due to various causes attending orthopaedic department of The Oxford Medical College and research centre, Bangalore from October 2018 to May 2019. All patients aged 18 to 60 years with history of knee injury who underwent clinical examination, radiographic examination, MRI and arthroscopy. The data was entered in MS Excel and analysed using SPSS.

Results: The study consisted of patients aged between 18-60 years (mean age 32.5 years). Out of which 59 were male and 31 were female. There were 54 patients with suspect diagnosis of medial meniscal tear and 36 with lateral meniscal tear. The difference in diagnostic values between the clinical andMRI findings in diagnosing the medial and lateral meniscal injuries were minimal.

Conclusions: Ligament injuries of knee are more common with sports injuries and high velocity trauma. A well-trained surgeon can be more reliable than MRI in diagnosing the ligament injuries. Since MRI is expensive, it can be skipped and used only in more doubtful and complex knee injuries.

Purpose: 5-HT2AR exists in high and low affinity states. Agonist PET tracers measure binding to the active high affinity site and thus provide a functionally relevant measure of the receptor. Limited in vivo data have been reported so far for a comparison of agonist versus antagonist tracers for 5-HT2AR used as a proof of principle for measurement of high and low affinity states of this receptor. We compared the in vivo binding of [11C]CIMBI-5, a 5-HT2AR agonist, and of the antagonist [11C]M100907, in monkeys and baboons. Methods: [11C]CIMBI-5 and [11C]M100907 baseline PET scans were performed in anesthetized male baboons (n=2) and male vervet monkeys (n=2) with an ECAT EXACT HR+ and GE 64-slice PET/CT Discovery VCT scanners. Blocking studies were performed in vervet monkeys by pretreatment with MDL100907 (0.5 mg/kg, i.v.) 60 minutes prior to the scan. Regional distribution volumes and binding potentials were calculated for each ROI using the likelihood estimation in graphical analysis and Logan plot, with either plasma input function or reference region as input, and simplified reference tissue model approaches. Results: PET imaging of [11C]CIMBI-5 in baboons and monkeys showed the highest binding in 5-HT2AR-rich cortical regions, while the lowest binding was observed in cerebellum, consistent with the expected distribution of 5-HT2AR. Very low free fractions and rapid metabolism were observed for [11C]CIMBI-5 in baboon plasma. Binding potential values for [11C]CIMBI-5 were 25-33% lower than those for [11C]MDL100907 in the considered brain regions. Conclusion: The lower binding potential of [11C]CIMBI-5 in comparison to [11C]MDL100907 is likely due to the preferential binding of the former to the high affinity site in vivo in contrast to the antagonist,  [11C]MDL100907, which binds to both high and low affinity sites.

Published: July 2019

Purpose. Status epilepticus (SE) is characterized by recurrent seizure activity and can be drug-resistant. Knowledge of neuronal and metabolic activity of the brain during SE may be helpful to improve medical care. We here report the effects of three anti-seizure drugs on changes of acetylcholine energy metabolites and oxidative stress during SE. Methods. We used the lithium-pilocarpine model in rats to induce SE and in vivo-microdialysis to monitor cholinergic and metabolic activity in the hippocampus. We measured extracellular concentrations of acetylcholine, glucose, lactate, pyruvate, glycerol and isoprostanes before and during SE, and after acute treatment with pregabalin, valproic acid, and levetiracteam. Results. Upon onset of  SE, acetylcholine (ACh) release increased six- to eightfold. Glucose was increased only transiently by 30% but lactate levels rose four-fold, and extracellular concentrations of glycerol ten-fold. Isoprostanes are markers of oxidative stress and increased more than 20-fold. Two hours after pilocarpine adminstration, rats were treated with pregabalin (100 mg/kg), levetiracetam (200 mg/kg) or valproic acid (400 mg/kg) by i.p. injection. All three drugs stopped seizure activity in a delayed fashion, but at the doses indicated, only animals that received levetiracetam reached consciousness. All drugs reduced ACh release within 60-120 minutes. Lactate/pyruvate ratios, glycerol and isoprostanne levels were also reduced significantly after drug administration. Conclusions. Hippocampal ACh release closely follows seizure activity in SE and is attenuated when SE subsides. Pregabalin, valproic acid and levetiracetam all terminate seizures in the rat SE model and attenuate cholinergic and metabolic changes within two hours.

Published: July 2019

The invention of Augmented Reality (AR) has provided a platform for individuals to see virtual and real objects simultaneously in a real-life setting. As compared to other technologies being implemented in education setting, it may contribute a new method to educate. This study investigated the possible effect of AR technology on students’ spatial visualization ability. AR-Science Magic Book Learning System (AR-SMB) is a learning tool based on the AR technology which was developed in this study to facilitate students in learning science concept, hence enhancing their spatial visualization ability. The type of data collection methodology used is the quantitative approach in which pre-test and post-test design were implemented and the participant comprised of 34 fifth-grade students. According to the results, it was found that the scores of the Mental Rotation Test (MRT) post-test were significantly greater than the pre-test, thus AR technology can be considered to be beneficial in enhancing students’ spatial visualization ability. There is a huge difference in terms of the scores of MRT between the pre-test and post-test which concludes that the treatment given can significantly improve and contribute towards their spatial visualization ability. The findings of this research enable the educators to incorporate AR learning into their teaching process in order for students to understand the rotation and transformation of objects that are related to each other. As a result, this study has shown a significant implication for the understanding of AR’s effect in enhancing spatial visualization ability among primary school students.

Published: July 2019

The present work deals with the effects of laminate arrangement on the failure behaviour of hybrid composite plates under transverse sinusoidal load. Failure analysis has been a subject under study for many years, especially for composite materials. This is largely due to the spontaneous nature of composite materials when it fails without warning. Hybrid composite are commonly utilized to improve the unexpected and instantaneous failure mode of composites. Nevertheless, the failure behaviour of hybrid composites is still not well understood. Moreover, studies have not exploited the effects on sinusoidal transverse loading on hybrid composites. Therefore, the first and last ply failure of the hybrid composite laminate was simulated and analysed using built in failure criteria function in ANSYS. The hybrid composite consisted of graphite (GR) and glass (GL), with lamination schemes of [GL/GL/GL/GL], [GL/GL/GL/GR] and [GR/GL/GL/GL] were subjected of transverse sinusoidal loading.  The laminate failure was predicted using the Maximum Stress Theory. Prior to determining the first and last ply failure of the hybrid composite plate, numerical validation was conducted to ensure the accuracy of the finite element software. The failure curves of the first ply failure and last ply failure were plotted and the results showed significant difference in the correlation of loadings that caused first and last ply failures and the lamination scheme of the hybrid composite plates. Thus, it can be said that the present work proves to be of importance and valuable in the field of study as well as enriching the knowledge regarding the failure behaviour of hybrid composite plate under transverse sinusoidal load of different laminate arrangement.

Published: July 2019

Unreinforced masonry (URM) houses are very weak against earthquake and many of them were collapsed or heavily damaged and killed many people during past large earthquakes, such as 2015 Nepal earthquake, 2010 Haiti earthquake, 2009 Padang earthquake, etc. Most URM buildings are built with little deliberation of seismic loading, and so these are not capable of resisting the seismic ground motion, which caused damage and collapse of the buildings. Based on these circumstances, retrofitting of URM structures is the prominent issue for earthquake disaster mitigation, especially for reducing human casualty. For this reason, there are many kinds of retrofitting materials and methods have been developed and used to strengthen the URM houses, such as Fiber Reinforced Polymers (FRP), steel mesh cage, surface treatment using Shotcrete, post-tensioning using rubber tires, etc. They can contribute somehow to increase strength and modulus for structural applications. However, they are relatively expensive and not available in many parts of the world, which is of prime importance in the third world countries. Therefore, in this paper, a new retrofitting material that is Abaca Fiber Reinforced Mortar (FRM) will be proposed. Abaca fiber, which is known as a natural material and available in local community, is used as a reinforcement in cement lime mortar. The experimental method used in this research consists of the tensile test of Abaca fiber, the in-plane and out of plane method. Based on the experimental test results, FRM methods have high potency to be used as retrofitting method of URM houses, due to its bigger deformation capacity and ease on application.

Published: July 2019

The role of the shopping center or mall becomes more important because of people likely to consider quality, service, and safety in shopping as their priorities. People will not have these when shopping in traditional markets. Shopping trolleys are transported tool that makes it easy for customers to shop, to carry purchased items in large quantities from one place to another at once. The problem that often occurs in the mall is not providing shopping trolleys that covers all areas of shopping, so do in Rita Pasaraya Tegal. Customers should hand-carry their purchased items. If the condition happened continuously, it would cause nerve trauma (carpal tunnel syndrome). Another problem is customer’s tiredness when shopping because they have to walk around the vastness of all shopping areas in Rita Pasaraya Tegal. This study aims to design a portable shopping trolley with a scooter to minimize such impact. Furthermore, the Kansei engineering method is used to determine the parameter of design. This method can translate human’s expression or needs into design so that the product fits what customers wish. The result of this research founds that five Kansei words represent customer’s desire in designing portable shopping trolley with a scooter; fine design, not big, strong, easy to handle, and safe. Moreover, the concept design made has already meet customers wishes with Z-value of Stuart Maxwell test of marginal homogeneity greater than 0.05.

Published: July 2019

In the last five years, there have been many Android applications implementing video filter or video effect as an excellent feature. Open CV is an open source computer vision library that can be simply and easily used for video filtering in Android application. However, using OpenCV library for video filtering commonly yields a bigger size of Android application. The concept of “Develop for Billion People” has enforced the developers to optimize the size of their applications to preserve resources and size of memory—as not all Android devices come with sufficiently large memory. On the other hand, OpenGL ES does not burden the filtering process because of its smaller size when it is implemented during the application development. In this research, we present a new native video processing technique using OpenGL ES. We implement the proposed method on a native video file without decreasing its quality before video filtering process. The experiments were conducted with five different mobile devices. We compared several metrics including: quality of the resulted video, file size of the apk, power consumption, and memory usage. Based on the experimental results, OpenGL ES produces smaller file size of apk (2 MB) compared with the produced file size of apk by Open CV (20MB). The resulted file after video filtering possesses same properties as observed before video filtering. Additionally, OpenGL ES uses more efficient power with 0.1965 mAh, while OpenCV consumes 0.283 mAh. Finally, video filtering with OpenGL ES uses 29.3% lesser memory than video filtering with OpenCV. The proposed method is proven to be more appropriate with “Develop for Billion People” as it preserves more computational resources compared with the existing video filtering technique in Android.

Published: July 2019

In the world of aquaculture, understanding the condition of a pond is very important for a farmer in deciding which action should they take to prevent any bad condition occurred. Condition of a pond can be justified by measuring plenty of water parameters which can be divided into 3 categories that are physical, chemical and biological. The physical parameter is any physical quantity that can be measured in the pond. The chemical parameter is any kind of chemical substances that are dissolved in water. The biological parameter is any organic matter that lives in water. However, all of these parameters are not so distinguishable in representing the condition of a pond. Therefore, the farmer experience difficulties in justifying the condition and taking proper action to their pond. Even with the help of the K-Nearest Neighbors (KNN) algorithm combined with grid search optimization to model the data, the result is still not satisfying where the model only achieve accuracy of 0.701 in leave one out validation. To overcome this problem, a kind of feature extraction algorithm is needed to extract more information and make the data become more differentiate in representing the condition of the pond. With the help of our proposed feature extraction algorithm, optimized KNN can model the data easier and achieve higher accuracy. From the experiment results, the proposed feature extraction algorithm gives an impressive performance where it increases the accuracy to 0.741. A comparison with other feature extraction algorithms such as Principal Component Analysis (PCA), Non-negative Matrix Factorization (NMF), and Singular Value Decomposition (SVD) is also conducted to validate how good the proposed feature extraction algorithm is. As a result, the proposed algorithm is surpassing the other algorithms which only achieve the accuracy of 0.707, 0.718, and 0.718, respectively.

Published: July 2019

The damage on infrastructures as well as environmental losses can be triggered by abrasion. That is why abrasion is included one kind of concerning disasters in Indonesia. West Sumatra is one of the provinces in Indonesia where its shoreline faces directly to the Indian Ocean. The West Sumatra shoreline abrasion phenomena have been recorded since earlier year 1900s. Abrasion prevention structures generally can be used to minimize the damage in near shore infrastructures. Cobblestone type groin is the most popular abrasion prevention structures to protect coastlines in the West Sumatra. West Sumatra groins were usually placed directly on the beach sand. The stability of the kind of groins is then greatly influenced by the mechanical state of the soil. Practically, the groins were designed in the static state which considers self-weight and the wave forces. In fact, due to dynamic forces the stability of the groins can be reduced. The external dynamic forces can increase in inertia forces and the change of the soil condition. Earthquake may lead the groins' base soil to liquefy which can disrupt the stability of the groins in terms of loss of bearing capacity. This study described the numerical simulation results to observe groin stability due to liquefaction. The liquefaction phenomena is simulated by increasing the applied pore pressure in the soil mass. The simulation results are then plotted in terms of shear-normal stress diagrams. The groin stability is then observed using the Mohr-Coulomb failure criterion. This study found that groin stability is not only disrupted by full liquefaction, but the liquefaction state can also disrupt the groin stability. It is also found that the groin dimensions affect the stability against a certain liquefaction level.

Published: July 2019

E-commerce is one of the most popular service applications in the world in the last decade. It has become a revolutionary model from traditional shopping transaction to entire internet commerce. E-commerce needs essential artificial intelligence (AI) to provide the customer with information about a product, called a recommendation machine. Collaborative filtering is a model of a recommendation algorithm that relies on rating as the fundamental calculation to make a recommendation. It has been successfully implemented in e-commerce. Even so, this model has a weakness in sparse product data in which the rating number is very low or sparse. Mostly, only less than 3% of the total user population rate a product, leading to the rise of sparse data. A text sentence document is a part of customers’ feedback that can be converted into a product rating.  According to a traditional approach, bag of word and lexicon model are ignored in a contextual approach. This experiment, it developed a new model to increase the contextuality of text sentences, leading to a more effective rating prediction. We employed a kind of convolutional neural network to generate item latent factor vectors that could be incorporated with probabilistic matrix factorization to make rating prediction. Our method outperformed several previous works based on a metric evaluation using the Root Mean Squared Error (RMSE). In this experiment, we analyzed MovieLens and IMDB datasets, which contained a movie product review.

Authors: Volkov S.S. , Rozanov D.S. , Shestel L.A.
Published: July 2019

In this work, possible methods of ultrasonic welding of synthetic fabrics are considered and analyzed. Technological features of ultrasonic seam welding of synthetic fabrics are described. The key parameters of this type of welding that significantly influence the speed of achieving the maximum temperature in the fabric welding zone are identified. These parameters determine the intensity of the fabrics’ warm-up, and therefore, the efficiency of the welding process. Thermal processes occurring at seam welding of synthetic fabrics are studied. It is established that the welding time increases with an increase in the number of connecting layers as well as with addition of cotton to the fabric composition. It is determined that when welding synthetic fabrics of small thickness, heat removal to the waveguide and the support roller has virtually no influence on the maximum temperature at the border of the mating surfaces and on the time of achieving the maximum temperature. Experiments on welding lavsan, kapron and polypropylene fabrics are conducted. The dependence of the statistic welding pressure on the welding speed and the fixed gap between the waveguide and the support roller is investigated. It is determined that the movement of material under the waveguide doesn not have a warming-up impact on the neighbouring areas of the welded seam. The strength of the welded joints practically does not depend on the height and shape of the support roller.

Nacobbus aberrans sensu lato es uno de los nematodos más importantes en el cultivo de jitomate. Para su manejo, es de importancia el estudio de estrategias sostenibles como la resistencia genética, comúnmente encontrada en parientes silvestres de los cultivos. Al respecto, surgió el interés por conocer la respuesta de poblaciones locales (Michoacán, México) de jitomate silvestre (Solanum lycopersicum var. cerasiforme) a la inoculación con juveniles de segundo estadio de N. aberrans s.l. Se montaron tres experimentos (E1, E2, y E3). Se evaluaron cinco genotipos silvestres y uno cultivado (cv. Río grande). A los 7 y 21 días posteriores a la inoculación (dpi) se evaluó el número de nematodos dentro de la raíz, y a los 45 y 60 dpi el agallamiento de raíces. En E1 y E2, a 7 y 21 dpi se encontraron los estadios J2 y J3-J4. En los tres experimentos ocurrió agallamiento, y a 60 dpi la producción de huevos fue evidente. N. aberrans s.l. invadió las raíces, y completó su desarrollo y reproducción. Estos resultados revelan la aptitud de las cinco poblaciones mexicanas de jitomate silvestre como hospedantes del nematodo, y sugieren la necesidad de explorar otras solanáceas silvestres como posibles fuentes de resistencia al nematodo.

How Net Radiation on Forested Snowpack Changes across a Latitudinal Gradient
Authors: Seyednasrollah Bijan , Kumar Mukesh
Published: July 2019

Radiation is the major driver of snowmelt, and hence its estimation is critically important. Net radiation reaching the forest floor is influenced by vegetation density. Previous studies in mid-latitude conifer forests have confirmed that net radiation decreases and then subsequently increases with increasing vegetation density, for clear sky conditions. This leads to existence of a net radiation minimum at an intermediate vegetation density. With increasing cloud cover, the minimum radiation shifts toward lower densities, sometimes resulting in a monotonically increasing radiation with vegetation density. The net radiation trend, however, is expected to change across sites, affecting the magnitude and timing of individual radiation components. This research explores the variability of net radiation on snow-covered forest floor for different vegetation densities along a latitudinal gradient. We especially investigate how the magnitude of minimum/maximum radiation and the corresponding vegetation density change with the site geographical location. To evaluate these, the net radiation is evaluated using the Forest Radiation Model at six different locations in predominantly white spruce (Picea glauca) canopy cover across North America, ranging from 45 to 66°N latitudes. Results show that the variation of net radiation with vegetation density considerably varies with latitude. In higher latitude forests, the magnitude of net radiation is generally smaller, and the minimum radiation is exhibited at relatively sparser vegetation densities, under clear sky conditions. For interspersed cloudy sky conditions, net radiation non-monotonically varies with latitude across the sites, depending on the seasonal sky cloudiness and air temperature. Latitudinal sensitivity of net radiation is lower on north-facing hillslopes than on south-facing sites.

Condition monitoring of bearings is an open issue. The use of the stator current to monitor induction motors has been validated as a very advantageous and practical way to detect several types of faults. Nevertheless, for bearing faults the use of vibrations or sound generally offers better results in the accuracy of the detection although with some disadvantages related to the sensors used for monitoring. To improve the performance of bearing monitoring, it is proposed to take advantage of more information available in the current spectra, beyond the usually employed, incorporating the amplitude of a significant number of sidebands around the first eleven harmonics, growing exponentially the number of fault signatures. This is especially interesting for inverter-fed motors. But, in turn, this leads to the problem of overfitting when applying a classifier to perform the fault diagnosis. To overcome this problem, and still exploit all the useful information available in the spectra, it is proposed to use shrinkage methods, which have been lately proposed in machine learning to solve the overfitting issue when the problem has much more variables than examples to classify. A case study with a motor is shown to prove the validity of the proposal

Cistus incanus L. (CI) has been proposed as an innovative functional supplement of food products, and hence the present study aimed to evaluate the effect of the addition of dried CI on the properties of bread. Bread was prepared from white wheat flour supplemented with the addition of 1%, 2%, 3%, 4%, and 5% of ground CI. After the completion of baking process, various characteristics of the obtained bread product, such as yield, volume, porosity, acidity, color, and texture, were evaluated. In addition, total phenolic content (TPC), ABTS radical scavenging activity, CHEL chelating power, and ability to quench OH∙ radicals were measured. The results showed that the addition of CI to bread caused a reduction in the volume of bread, but texture of the crumbs was acceptable. Acidity and moisture content of bread were found to be increased following CI enrichment. Significant changes in the ash content and the color of bread crumbs were also observed. Bread incorporated with CI was characterized by significantly higher TPC and much higher antioxidant activity, as measured by ABTS, CHEL, and OH∙ radicals, compared to control bread. Supplementation of bread with 3% CI produced a product with desirable characteristics which was also favored by consumers.

The rapid process of urbanization is affecting residents’ living patterns. Concurrently, shopping and consumption patterns are changing at what seems to be a constant rate. Recently, a look at retail centers would leave one to understand that these centers are by no means exempted from these changes. Retail centers, which initially held a more commercial role, are now considered to be places of leisure as well as. In this research, the new role of these retail centers as a new part of public spaces and area for leisure activities is being examined. In order to survey this new concept of retail centers, two retail centers that were almost similar to each other in terms of function and characteristics in Iran and Spain respectively, considered as a developing country and developed country were studied. The results of the research show that retail centers, due to their new nature, have shown similar behavior in both. In general, nowadays retail centers have more of a recreational role, so that more than 65% of the people in Tehran and Madrid are spending their time in recreational activities. Nevertheless, in developing countries, the process of these changes has been imitative and to say anything of cross-sectoral policies it will require more research.

Swift and diligent resilience response is mandatory in sustainable geo-distributed ecosystems. The real-time geo-spatial resilience requires agility in millions of parallel and distributed data processing tasks on data acquired from regional condition monitoring(RCM) systems. These tasks include expiditous resolution of complex sustainability conflict sets, promptly anomalies characterization in chaos sets, and resilience response uniqueness. This work is an archetype of a paragon geo-resilience support system(GRSS) for regional sustainability using a novel melioration in DADO production machine. The proposed expert system capitalized the synergic strengths of RETE, TREAT, LEAPS and GATOR networks was designed and implemented as a synthetic DADO machine(SDM). The generic architecture of DADO machine was improved in this work by enrichment in rule set conditions and solution set for regional scale resilience rule set conditions. The condition left-hand side(LHS) X equal to the solution set 2X for right-hand side (RHS) was the goal achieved by working memory(WM) optimization and conflict resolution strategy(CRS) in alpha and beta networks rules. A round-trip time of 80.2 seconds for first event response set using 1492 segment size and sequence number 360,000 with maximum packets at a single geospatial structure was 21 packets/sec was a noticeable landmark in this work. LEAPS and Concurrent-read algorithm for GATOR cluster networks in the proposed synthetic DADO machine architecture was the overall implementation that enabled urban scale resilient system practically possible on physical SHM deployment.

Waste orange peel represents a heavy burden for the orange juice industry, estimated in several million tons per year worldwide; nevertheless, this by-product is endowed with valuable bioactive compounds, such as pectin, polyphenols and terpenes. The potential value of the waste orange peel has stimulated the search for extraction processes, alternative or complementary to landfilling or to the integral energy conversion. This study introduces controlled hydrodynamic cavitation processes, as a new route to the integral valorization of this by-product, based on simple equipment, speed, effectiveness and efficiency, scalability, and compliance with green extraction principles. Waste orange peel, in batches of several kg, was processed in more than 100 L of water, absent any other raw materials, in a device comprising a Venturi-shaped cavitation reactor. The extractions of pectin, endowed with a very low degree of esterification, polyphenols (flavanones and hydroxycinnamic acid derivatives), and terpenes (mainly d-limonene) were effective and fast (high yield, few min of process time), as well as the biomethane generation potential of the process residues was effectively exploited. The achieved results proved the viability of the proposed route to the integral valorization of waste orange peel, though wide margins exist for further improvements.

A hand-held laser-induced breakdown spectroscopy device was used to acquire spectral emission data from laser-induced plasmas created on the surface of cerium-gallium alloy samples with Ga concentrations ranging from 0 to 3 weight percent. Ionic and neutral emission lines of the two constituent elements were then extracted and used to generate calibration curves relating the emission line intensity ratios to the gallium concentration of the alloy. The Ga I 287.4 nm emission line was determined to be superior for the purposes of Ga detection and concentration determination.A limit of detection below 0.25% was achieved using a multivariate regression model of the Ga I287.4 nm line ratio versus two separate Ce II emission lines. This LOD is considered a conservative estimation of technique’s capability given the type of the calibration samples available and low power( 5 mJ per 1 ns pulse) and resolving power (λ/∆λ= 4000) of this handheld device. Nonetheless, the utility of the technique is demonstrated via a detailed mapping analysis of the surface Ga distribution of a Ce-Ga sample which reveals significant heterogeneity resulting from the sample production process.
