A Novel Deep Convolutional Neural Network for Tuberculosis Detection

India accounts for the world’s largest number of cases in TB, with 2.8 million cases annually, and accounts for more than a quarter of the global TB burden. Tuberculosis (TB) is caused by the bacterium (Mycobacterium tuberculosis) which most commonly affects the lungs. TB is transmitted from person to person through the air. When people with TB cough, sneeze or spit, the germs are propelled into the air. This paper showcases a methodology which uses a Deep Learning Model (dCNN) for the detection of Tuberculosis in the lungs. The accuracy obtained by the methods for the model is desirable and dependable, which is increasingly productive in contrast to the accuracy shown by other neural networks.
Genetic structure of Cydia pomonella populations in Argentina and Chile implies isolating barriers exist between populations

The codling moth (Cydia pomonella (L.)) is an invasive pest of pome fruits introduced to the Americas in the 19–20th centuries. This pest is widespread on both sides of the Andes range separating Argentina and Chile. We performed an analysis of the population genetic variability and structure of C. pomonella in Argentina and Chile using 13 microsatellite markers and sampled C. pomonella from apple as the main host plant along its distribution area (approx. 1,800 km). A total of 22 locations (11 from Chile and 11 from Argentina) were sampled. Significant genetic differentiation was observed among samples from Argentina and Chile (FSC = 0.045) and between all localities (FST = 0.085). Significant isolation by distance (IBD) was found for each country and when samples from both sides of the Andes range were pooled, although a lower correlation coefficient was observed. The Mantel test showed that the geographic distance and highest altitude of the mountains between locations were significantly associated with the pairwise FST when samples from both sides of the Andes range were pooled. According to a Bayesian assignment test (STRUCTURE), samples from Argentina and Chile conformed to two distinct genetic clusters. Our results also suggest that the recent invasion of C. pomonella in the southernmost localities (Aysén Region in Chile and Santa Cruz Province in Argentina) originated in populations from the respective sides of the Andes range. Our results indicate a genetic exchange of C. pomonella within each country and significant genetic differentiation between countries, which could be explained by dispersal mediated by human activities related to fruit production within each country with little exchange between them. A possible explanation is that the Andes range could be a significant barrier for dispersal by flight, and quarantine barriers could prevent the movement of plant material or infested fruit between countries.
APPLICATION OF WAVELET TRANSFORM FOR PHASE-TO-GROUND FAULT PROTECTION IN MEDIUM VOLTAGE ELECTRICAL NETWORKS

For electrical networks with voltage of 6-35 kV with a compensated, isolated or resistor-grounded neutral, a phase-to-ground protection has been developed, in which, based on the results of the time-frequency wavelet transform of zero-sequence currents, voltages and their derivatives, using the obtained analytical expression, the total reactive power wavelet for different frequencies is determined. It is shown that at the initial moment of a phase-to-ground fault on the damaged feeder the power is always positive, and on the undamaged feeder it is negative, regardless of the operating mode of the neutral. Wavelet transform coefficients are found by convolution of discrete values of measured signals with sine-cosine signals of the Morlet mother function. The time-reversed sequence of these signals is obtained using a matrix for which the rules for its formation are stated. An excess of the zero phase sequence voltage amplitude of the set value is used as a starting protection element. With the help of a mathematical model of the network, studies of the behavior of protection in case of blind and arc phase-to-ground faults at various degrees of compensation of capacitive currents, at various voltage values at the moment of the short circuit have been carried out. In all modes, a reliable protection operation is obtained, the sensitivity of which is an order of magnitude higher than the protection based on Fourier transforms. Positive results of testing a protection sample implemented on a microprocessor-based element base at a laboratory stand are obtained. References 20, figures 7, tables 2.
Parameter Identification of BLDC Motor Using Electromechanical Tests and Recursive Least-Squares Algorithm: Experimental Validation

In this article, the parameter identification of a brushless DC motor (BLDC) is presented. The approach here presented is based on a direct identification considering a three-phase line-to-line voltage electromagnetic torque as function of the electric currents and rotor speed. The estimation is divided into two stages. First, the electrical parameters are estimated by well-known no-load and DC tests. Consequently, estimation of mechanical parameters is performed using a recursive Least Square Algorithm. The proposed approach is validated by comparing model responses to motor real time responses. Additionally, the design, digital simulation and real time implementation of a PI rotor speed controller, based on the estimated model, validate the identification proposal presented here.
Segmentation based on recreational experiences in coastal and marine destinations: a study in Acapulco, Mexico

ABSTRACT Coastal and marine destinations that offer recreational activities can enhance visitors’ experiences and promote their environmental responsibility. The objective of this study was to carry out a market segmentation of the domestic tourism demand based on recreational experiences in a coastal and marine destination. This in-situ research was conducted in Acapulco, an important destination in Mexico. A total of 441 questionnaires were obtained and analyzed. Factorial analysis was applied as a data reduction technique and K-means clustering as a case grouping method. Four dimensions of recreation experiences emerged: experiential reflection, experiential learning, ecological observation, and sensory and experiential. Also, four segments of tourists were found based on their recreation experiences: ‘multiple-experience recreationists,’ ‘hedonists,’ ‘knowledge seekers,’ and ‘aestheticists. ’ The findings will serve as management guides for tourist destinations managers and will help companies in the sector to create efficient marketing plans.
Contemporary Kinetic Theory of Matter

This powerful, theoretical framework allows a quantitative treatment of many non-equilibrium phenomena such as transport processes in classical and quantum fluids. This book describes in detail the Boltzmann equation theory, obtained in both traditional and modern ways. Applications and generalizations describing non-equilibrium processes in a variety of systems are also covered, including dilute and moderately dense gases, particles in random media, hard sphere crystals, condensed Bose-Einstein gases, and granular materials. Fluctuation phenomena in non-equilibrium fluids, and related non-analyticities in the hydrodynamic equations are also discussed in some detail. A thorough examination of many topics concerning time dependent phenomena in material systems, this book describes both current knowledge as well as future directions of the field.
Conception de vecteurs polymères pour l’imagerie moléculaire et le traitement ciblé de la thrombose

Les pathologies de la paroi arterielle, et notamment l’atherosclerose, sont responsables de plus de 25% des deces dans le monde. Ces pathologies sont a l’origine de la thrombose,caracterisee par l’occlusion d’une artere par un caillot, ou thrombus. Ce travail de these explore l’utilisation de nanoparticules et microparticules polymeres pour ameliorer le diagnostic et le traitement de la thrombose. Ce type de particules permet en effet d’associer des agents de contraste et des actifs therapeutiques a des agents de ciblage pour favoriser leur accumulation specifique au niveau du thrombus. Les particules sont formulees a partir de polysaccharides et/ou de poly(cyanoacrylate d’isobutyle). Elles sont fonctionnalisees en surface avec du fucoidane, un polysaccharide naturel extrait d’algues brunes. Le fucoidane presente une affinite tres forte pour la P-selectine, molecule exprimee par les plaquettes activees qui constituent en partie le thrombus. Au cours de ce projet, un test in vitro d’adhesion en flux a ete mis au point pour valider l’interaction des systemes developpes avec leur cible moleculaire, la P-selectine, et leur cible cellulaire, les plaquettes activees. L'agent therapeutique standard utilise pour induire la degradation du thrombus est l’activateur tissulaire du plasminogene. Celui-ci a ete charge sur des nanoparticules copolymeres fonctionnalisees avec du fucoidane. L’efficacite de ces systemes a ensuite ete validee dans un modele murin de thrombose. Enfin, des nanoparticules composees exclusivement de polysaccharides et entierement hydrophiles, dites “nanogels”, ont ete synthetisees par un procede innovant. Les resultats obtenus dans ce travail de these confirment le fort potentiel des approches ciblees pour le diagnostic et le traitement de la thrombose. Ils contribuent d’une maniere plus generale au developpement de la medecine personnalisee dans le domaine cardiovasculaire.
In-Situ Reduction of Mo-Based Composite Particles during Laser Powder Bed Fusion

Raw powders are processed in water during the freeze-dry pulsated orifice ejection method (FD-POEM), leading to the inclusion of oxygen impurities. This study proposes a strategy for removing the oxygen content and enhancing the mechanical performance of laser powder bed fusion (L-PBF) builds from powders using carbon nanotubes (CNTs) and H2 reduction. Spherical 1.5 wt. % CNT/Mo composite powders with uniform dispersion were fabricated via FD-POEM. The quantity of MoO2 decreased significantly, and a hexagonally structured Mo2C phase was simultaneously formed in the L-PBF build. The Mo2C with network structure was distributed along the boundaries of equiaxed Mo grains, leading to an increased Vickers hardness of the matrix. This study demonstrates the feasibility of fabricating oxygen-free and high-strength refractory parts during L-PBF for ultrahigh-temperature applications.
Numerical Study of a Reconfigurable Multiband Microwave Photonic Filter Using a Tunable Fabry-Perot Filter

Microwave photonic filters (MPFs) with the capabilities of bandwidth reconfigurability and frequency tunability in the GHz range are of great interest in high-speed communications systems. In this paper, we propose a new reconfigurable multiband microwave photonic filter (MPF) using a tunable Fabry–Perot Filter (FPF). It is demonstrated by numerical simulations that the modification of the intermodal separation (δλ) of a multimode laser diode (MLD) by tunable FPF allows for the reconfigurable multi-passband of the MPF. Our simulation results show that our new filter system is promising to communications systems.
Antibacterial Activity and Characterization of Bacteria Isolated from Diverse Types of Greek Honey against Nosocomial and Foodborne Pathogens

It has been suggested that microorganisms present in honey are a potential source of antimicrobial compounds. This study aimed to isolate and characterize bacteria from 46 Greek honey samples of diverse botanical and geographical origin and to determine whether these bacteria demonstrate antibacterial activity against five important nosocomial and foodborne pathogens. In total, 2014 bacterial isolates were obtained and screened for antibacterial activity. Overall, 16% of the isolates inhibited the growth of Staphylococcus aureus, 11.2% inhibited the growth of Pseudomonas aeruginosa and Acinetobacter baumannii, 10.2% inhibited the growth of Salmonella Typhimurium and 12.4% of the isolates affected the growth of Citrobacter freundii. In total, 316 isolates that inhibited the growth of more than two of the tested pathogens were grouped by restriction fragment length polymorphisms (RFLP) analysis of the 16S rRNA gene amplicon. Fifty of them were identified by 16S rRNA gene sequencing. The majority, 62% of the isolates, belonged to the genus Bacillus. Only 10% of the isolates were identified as Gram-negative bacteria. Furthermore, in several bacterial isolates, genes encoding polyketide synthases and nonribosomal peptide synthetases that catalyze the biosynthesis of secondary metabolites which might contribute to the exerted antimicrobial activity, were detected. This study demonstrates that honey microbiota exerts antimicrobial activity and is a putative source of secondary metabolites against important nosocomial and food pathogens that warrants further investigation.
Swollenin pre-conditioning: optimization studies and application aiming at d-lactic acid production from sugarcane bagasse

Abstract The enzymatic hydrolysis still stands as a challenge regarding the use of renewable feedstocks, as well as of lignocellulosic materials. The present work reports optimization of swollenin addition to pretreated sugarcane bagasse, in a step prior to the enzymatic hydrolysis, named pre-conditioning. Also, it describes further fermentation of the hydrolyzed material to d-lactic acid. Trichoderma harzianum enzymatic cocktail was produced from pretreated sugarcane bagasse, while swollenin was produced using Aspergillus niger as a host for recombinant protein expression. For pre-conditioning optimization, a Central Composite Rotatable Design was applied and validated. The optimized conditions were used to produce the hydrolysate that was fermented to D-lactic acid by Lactobacillus coryniformis subsp. torquens. It could be observed that pre-conditioning effectively leads to improvements in glucose release: 62% of hydrolysis efficiency. Besides, it was possible to use the produced hydrolysate to obtain d-lactic acid, with a yield of 1.34 g/g and a productivity of 1.59 g/L h−1.
Influence of INGER and TORDIS Energetic Willow Clones Planted on Contaminated Soil on the Survival Rates, Yields and Calorific Value

The paper presents some forestry aspects of using Inger and Tordis willow clones to obtain woody biomass and remedy degraded soils. The methodological aspects regarding the planting of willow seedlings, the evaluation of the survival rate, the evaluation of the biomass quantity and the enrichment of the soil are analyzed. The results of the experiments showed that the degraded soil decreased the viability rate of the cuttings by 16.6% for the Tordis clone and 35.8 for the Inger clone. The analysis of the soil samples showed that it was enriched in nutrients after 2 years of cultivation, by the decomposition of the fallen leaves on the soil and by the absorption of the substances from the soil. Regarding the amount of biomass, its mass per hectare after the first year of cultivation was 0.64 t/ha for the Inger clone and 0.66 t/ha for the Tordis clone, while the calorific values of 19,376 kJ/kg for Inger and 19,355 kJ/kg for Tordis were good values. The final conclusion of the paper highlights that Osier willow is a viable solution for obtaining energetic biomass and putting it back into the productive circuit of degraded soils.
Automatic Wheels and Camera Calibration for Monocular and Differential Mobile Robots

Mobile robotic systems are highly relevant today in various fields, both in an industrial environment and in terms of their applications in medicine. After assembling the robot, components such as the camera and wheels need to be calibrated. This requires human participation and depends on human factors. The article describes the approach to fully automatic calibration of a robot’s camera and wheels with a subsequent calibration refinement during the operation. It consists of placing the robot in an inaccurate position, but in a pre-marked area, and using data from the camera, information about the environment configuration, as well as the ability to move, in order to perform calibration without external observers or human participation. There are two stages in this process: the camera and the wheel calibrations. The camera calibration collects the necessary set of images by automatically moving the robot in front of the fiducial markers template, and then moving it on the marked floor, assessing its trajectory curvature. Upon calibration completion, the robot automatically moves to the area of its normal operation and it is proposed to refine the calibration during its operation without blocking its work. The suggested approach was experimentally tested on the Duckietown project base. Based on test results, the approach proved to be comparable to manual calibrations and is capable of replacing a human for this task.
Qualitative longitudinal research in family sociology

The combination of qualitative interpretative approaches and longitudinal research designs, although not new in the social sciences, is gaining increasing recognition as a useful and even necessary avenue to explore family changes as they occur. Qualitative methods, whether longitudinal or not, emphasise the understanding of meanings, subjective experience, and agency. The use of such methods can improve our comprehension of how people choose a given alternative and reject another, and how they adjust or fail to adjust to their living circumstances. At the core of qualitative investigation is also an interest in understanding the meaning of the experiences of social actors in their social contexts. In family research, numerous one-off studies have investigated how different individuals and groups create, interpret, and negotiate family relationships, roles, and transitions. The longitudinal approach adds to this tradition by focusing on the course of events, as well as on the processes of change, stability, and continuity through time. At the individual level, the combination of qualitative and longitudinal research enables us to capture how individuals create meanings about the turns of their lives and their circumstances as they unfold. For instance, it is indispensable to investigate how processes like those initiated by a chronic disease, a union dissolution, or the experience of social discrimination unfold from specific socio-cultural and biographic perspectives. While one-off qualitative approaches are widely used in family sociology and have often collected retrospective information, until recently, longitudinal prospective methods were more popular in quantitative studies.1 They are generally used to describe and measure the objective aspects of change, such as personal and social trajectories, like family relations and biographic events associated with educational, employment, and residential careers. While quantification assesses the regularities and the probability of the occurrence of social dynamics, such data are thin when it comes to accounting for the logic of the actions that underlie them. In contrast, by investigating agency and meanings, qualitative longitudinal research (QLR) has the potential to unravel the complexity of changes that are involved in the making and the unmaking of family relationships across the life course. This will not come as a surprise if we think of both agency and meanings as dynamic objects of study: individual agency co-produces the processes through which individuals live and, therefore, their experiences of change. Subjective meanings are shaped by social interactions, and shift in relation to life course events and transitions. QLR has started accumulating rich data on relational practices and multidimensional experiences of family and childhood across the life course, with change and temporality being central to their interpretation. Change can be conceived and qualitatively analysed at levels beyond just that of the individual, including at the couple, group, institutional, and societal
Invasion, retaliation, concealment and silences at Dead Man's Flat, South Australia: A consideration of the historical, archaeological and geophysical evidence of frontier conflict

ABSTRACT This article presents the results of historical research, as well as archaeological and geophysical surveys, in order to explore a number of frontier conflict events at Dead Man’s Flat in South Australia (SA). The historical records reveal the cruelty and complexity of the period and expose the concealments, contradictions, euphemistic language, denials and silences that are typical of the Australian frontier. Further disparities are revealed in more recent commemorative efforts. Archaeological investigations in the study area provided an ‘absence of evidence’. Whilst the geophysical survey revealed that there are potential graves located on the flat, no interment was located in the area commemorated by local non-Indigenous community members. The combined results of this multi-method approach uncovered new dissonances, raised new questions and provided new exegeses about the frontier in this region. For traditional owners, the sum of the evidence reveals a history of invasion, killings and massacre, theft, deceit and cover-up – Dead Man’s Flat is, therefore, a place to be approached with deep respect in order to honour the experiences of their ancestors.
Product Stewardship Taking Into Account The Satisfaction Of Consumer Preferences

Both consumers and producers of goods and services face the concept of “quality”. The quality of products that are carried out by enterprises is the basis for satisfying society's needs. The material resources that society has for its social and economic development largely depends on the quality of the products it produces. However, in our opinion, the brand market has replaced the product market. The quality of goods or services corresponds to the price that consumers agree to pay when they need to purchase these goods and services. We believe that the utility received by the buyer from the purchase of an additional service or product is equal to the customer's satisfaction from their purchase. Consequently, the quality of a product or service correlates with the value of their marginal utility for consumers. At the same time, the usefulness of the product for the consumer is not limited only by its durability, reliability, safety, and ease of maintenance. It can also be associated with the satisfaction of owning the product. This means that the quality of goods and services in the understanding of different consumers may differ, and the quality of products is subjective. For a modern buyer, their subjective assessment of the quality of the product may depend on the information posted about this product on the Internet.
