Development of a Control System for Multilink Manipulators on Unmanned Underwater Vehicles Dynamically Positioned Over Seafloor Objects

This article considers an approach to synthesizing a multilevel system to control movements of a multilink manipulator (MM) mounted on an unmanned underwater vehicle (UUV) for performing autonomous manipulative operations in the mode of dynamic positioning over various objects on the seafloor. The system is based on an upgraded method that, using point clouds received from the machine vision systems (MVS), provides high-accuracy determination of the shape and location of the work object relative to UUV. The preset trajectories of the MM working tool are overlaid on the identified surface of the object, with possible silting, fouling or deformation of the latter taken into account. To execute the programmed trajectories with the MM working tool, the following methods have been implemented in software: stabilization of UUV in hovering mode near the object, high-precision control of working tool’s movements, and also corrections of its trajectory taking into account UUV’s displacements relative to the object. The synthesized system has been developed in the C++ programming language. The operation of the system has been numerically simulated using a model of UUV with MM, as well as models of the environment and the target object, in the Matlab/Simulink and V-REP software packages. The results of the study show a high efficiency of the system both in processing sensor information and in providing the dynamic control of movements of an UUV with a MM.
Third World Multinationals: The Rise of Foreign Investment from Developing Countries

In the past decade, a number of Third World countries have emerged from their economic status as sources of raw materials or as sweatshops in which low-wage, low-skilled workers produced goods for the richer nations. Now they are themselves manufacturing and consuming high-quality, hightechnology products and are establishing foreign subsidiaries, most often in other developing countries. This book is the first to study the significantgrowth in foreign direct investment by such countries and its impact on the international economic order. Third World Multinationals explores the question of why firms based in developing countries have chosen to invest in branches, joint ventures, and wholly-owned subsidiaries overseas rather than simply export goods or enter into licensing arrangements abroad. In addition to the cost of transport, tariff barriers, and import restrictions, it identifies a number of less apparent factors, such as the motivations of managers in wanting to go abroad, the meshing of technological levels, ethnic ties, and the desire to protect proprietary processes and competitive advantages. The book compares the similarities and differences between these firms and their more established counterparts from the industrialized countries, both large and small. It examines the implications of these developments on the relations between specific home and host countries, and on North-South relations and South-South relations in general. In the face of scarce and unreliable figures, the author has compiled a considerable amount of validated data and viable estimates from numerous world sources. The cases and examples are taken mainly from South America and South and Southeast Asia, those regions that have put forth the largest number of multinational offshoots.

¡Despierta México! Changing Public Attitudes Toward NAFTA, 2008–2018

ABSTRACT Regional trade agreements have important consequences for developing countries, but the public opinion literature on trade agreements suffers from several shortcomings. Most significant is that studies tend to take a single year as the point of analysis, leaving us uncertain as to how opinion evolves. This study uses polling data to examine Mexicans’ attitudes toward NAFTA over a ten-year period. Results from regression analyses show an association between Mexicans’ support for the United Nations and their support for NAFTA, and a weaker relationship for other types of cues (presidential, the United States), than other studies have found. The data also reveal an association between Donald Trump’s arrival in the presidency and increased support for NAFTA.
Mesenchymal Stem Cells Isolated from Paediatric Paravertebral Adipose Tissue Show Strong Osteogenic Potential

Mesenchymal stem cells (MSCs) represent the basis of novel clinical concepts in cellular therapy and tissue regeneration. Therefore, the isolation of MSCs from various tissues has become an important endeavour for stem cell biobanking and the development of regenerative therapies. Paravertebral adipose tissue is readily exposed during spinal procedures in children and could be a viable source of stem cells for therapeutic applications. Here, we describe the first case of MSCs isolated from paravertebral adipose tissue (PV-ADMSCs), obtained during a routine spinal surgery on a child. Using quantitative real-time PCR and flow cytometry, we show that PV-ADMSCs have different levels of stem marker expression compared to the MSCs from other sources while having the highest proliferation rate. Furthermore, we evaluate the multipotency of PV-ADMSCs by the three-lineage (adipogenic, osteogenic and chondrogenic) differentiation and compare it to the multipotency of MSCs from other sources. It was found that the PV-ADMSCs have a strong osteogenic potential in particular. Taken together, our data indicate that PV-ADMSCs meet the criteria for successful cell therapy, defined by the International Society for Cellular Therapy (ISCT), and thus, could provide a source of MSCs that is relatively easy to isolate and expand in culture. Due to their strong osteogenic potential, these cells provide a promising basis, especially for orthopaedic applications.

Significant association with more than 3 times admission to hospital have previous history of exposure to smoking, inhaler use and X-ray finding. CONCLUSION: One to three years old children is the most common age they have recurrent wheezing, most children with recurrent wheezy chest have more than 3 times hospitalization, most babies have previous history of ICU admission, GERD and exposure to smoking.
Prevalence, Risk Factors and Impacts Related to Mould-Affected Housing: An Australian Integrative Review

In response to an Australian governmental inquiry into biotoxin-related illness, the purpose of this integrative review is to bring together the current state of evidence on the prevalence, risk factors and impacts related to mould-affected housing in an Australian context, in order to inform building, housing and health research, practice and policy. The robust integrative review methodology simultaneously sought quantitative and qualitative studies and grey literature from multiple disciplines, identifying only 45 studies directly relating to Australian housing and indoor mould. Twenty-one studies highlight negative health impacts relating to indoor residential mould, with asthma, respiratory, allergy conditions and emerging health concerns for chronic multiple-symptom presentation. The majority of studies reported risk factors for indoor mould including poor housing conditions, poor-quality rental accommodation, socioeconomic circumstance, age-related housing issues and concerns for surface/interstitial condensation and building defects in newer housing. Risks for indoor mould in both older and newer housing raise concerns for the extent of the problem of indoor mould in Australia. Understanding the national prevalence of housing risks and “root cause” associated with indoor mould is not conclusive from the limited existing evidence. Synthesis of this evidence reveals a lack of coverage on: (1) national and geographical representation, (2) climatical coverage, (3) housing typologies, (4) housing defects, (5) maintenance, (6) impact from urbanisation, and (7) occupant’s behaviour. This integrative review was key in identifying emerging housing and health concerns, highlighting gaps in data and implications to be addressed by researchers, practice and policy and acts as a comprehensive holistic review process that can be applied to other countries.

The Effect of Hypnobreastfeeding Technique on the Production of Breast Milk in Postpartum Mothers in Independent Practice Midwives

Breastfeeding is influenced by several factors, including breast milk does not come out immediately after giving birth, the baby's difficulty in sucking, the condition of the mother's nipples being unsupported, the mother working, and the influence/promotion of breast milk substitutes. The purpose of this study was to determine the effect of the hypnobreastfeeding technique on breast milk production in postpartum mothers at BPM Atikah, Panyabungan District. The research design is an analytic experimental pre-experimental type with a pretest-post test one group design approach. all postpartum mothers < 24 hours at BPM Atikah as many as 25 postpartum mothers, the sampling technique was total sampling. The results of the research on breast milk production before the hypnobreastfeeding technique was carried out in postpartum mothers were mostly less than 7-123 ml as many as 12 (48%) and after hypnobreastfeeding in postpartum mothers at BPM Atikah mostly good > 7-123 ml as many as 12 (48%). There is an effect of hypnobreastfeeding technique on milk production with a p value of 0.001 < 0.05. Postpartum mothers should increase their knowledge and experience in an effort to increase breast milk production so that mothers can give breast milk optimally.
Stage-Specific Non-Coding RNA Expression Patterns during In Vitro Human B Cell Differentiation into Antibody Secreting Plasma Cells

The differentiation of B cells into antibody secreting plasma cells (PCs) is governed by a strict regulatory network that results in expression of specific transcriptomes along the activation continuum. In vitro models yielding significant numbers of PCs phenotypically identical to the in vivo state enable investigation of pathways, metabolomes, and non-coding (ncRNAs) not previously identified. The objective of our study was to characterize ncRNA expression during human B cell activation and differentiation. To achieve this, we used an in vitro system and performed RNA-seq on resting and activated B cells and PCs. Characterization of coding gene transcripts, including immunoglobulin (Ig), validated our system and also demonstrated that memory B cells preferentially differentiated into PCs. Importantly, we identified more than 980 ncRNA transcripts that are differentially expressed across the stages of activation and differentiation, some of which are known to target transcription, proliferation, cytoskeletal, autophagy and proteasome pathways. Interestingly, ncRNAs located within Ig loci may be targeting both Ig and non-Ig-related transcripts. ncRNAs associated with B cell malignancies were also identified. Taken together, this system provides a platform to study the role of specific ncRNAs in B cell differentiation and altered expression of those ncRNAs involved in B cell malignancies.
What factors affect entrepreneurial intention in sharing accommodations? The application of the entrepreneurial event model

Hosts of sharing accommodation platforms are considered an evolving mode of entrepreneurs. This study aimed to examine the relationship among entrepreneurship capital (EC), perceived feasibility (PF), perceived desirability (PD), and entrepreneurial intention (EI) in sharing lodging by using the entrepreneurial event (SEE) model. Particularly, EC was evaluated as a second-order factor with four first-order sub-variables: financial, social, intellectual, and human capital (HC). Data were collected from online surveys completed by 328 respondents. Second-order factor analysis and structural equation modeling were used in the analysis. Results confirmed that all four sub-variables contributed to inclusive capital. Inclusive capital positively influenced PF and PD, which led to EI. This study contributes to the evolving knowledge of sharing accommodations and enriches the research body of entrepreneurship via examining hosts of sharing lodging as innovative micro-entrepreneurs. It offers practical tools to help prospective hosts assess whether they are ready to operate a sharing lodging business.
Modeled Early Longitudinal PSA Kinetics Prognostic Value in Rising PSA Prostate Cancer Patients after Local Therapy Treated with ADT +/− Docetaxel

Simple Summary In prostate cancer patients with rising prostate-specific antigens (PSAs) after primary local therapy, and at high risk of metastatic disease based on a high Gleason score or ISUP grades 4–5 and/or short PSA doubling time, androgen-deprivation therapy (ADT) was shown to be effective with or without salvage radiotherapy. In the present paper, the analysis of a phase III trial dataset comparing ADT +/− docetaxel demonstrates that longitudinal PSA kinetics during the first 100 days of treatment, assessed using mathematical modeling, is associated with patient prognosis. Indeed, multivariate analyses showed that the modeled PSA production rate constant KPROD, and the elimination rate constant KELIM, exhibited strong and independent prognostic values regarding PSA progression-free survival (PSA-PFS) and overall survival (OS), respectively. As it was shown with the longitudinal CA-125 kinetic in ovarian cancers, the modeled longitudinal PSA kinetics during the 100 days of treatment may represent a novel prognostic factor in patients with metastatic prostate cancers. Abstract Background: In metastatic prostate cancer (PCa) patients, androgen-deprivation therapy (ADT) combined with chemotherapy or next-generation androgen receptor targeted agents is a new standard treatment. The objective of the present study is to assess longitudinal PSA kinetics during treatment using mathematical modeling, to identify the modeled PSA kinetic parameters able to exhibit early prognostic/predictive values. Methods: Phase III clinical trial dataset (NCT00764166) comparing ADT +/− docetaxel in 250 locally treated patients for PCa with rising PSA levels, who were at high risk of metastatic disease was assessed. A kinetic-pharmacodynamic (K-PD) model was used to fit PSA kinetics during the first 100 treatment days, to estimate the modeled PSA production rate K (KPROD) and elimination constant rate K (KELIM). The prognostic value of these parameters, considered as categorized (favorable vs. unfavorable) covariates regarding PSA progression-free survival (PSA-PFS) and overall survival (OS), was assessed using univariate/multivariate analyses. Results: Data from 177/250 patients was assessed. KELIM exhibited a significant prognostic value regarding PSA-PFS and KPROD regarding OS (univariate analysis). In the PSA-PFS final multivariate model, KELIM and the primary therapy type were significant. The OS multivariate model integrated both KPROD and baseline PSA doubling-time. Conclusion: In this first study assessing the modeled PSA kinetics prognostic value in PCa patients treated with systemic treatments, KELIM and KPROD exhibited respective prognostic values regarding PSA-PFS and OS.
The Relationship between Physical Activity Level and Functional Status of Subjects with High Spinal Cord Injury

Background. Spinal cord injuries are one of disability in Poland and in the world. Methods: 80 subjects with a transverse injury of the cervical spinal cord were enrolled in the study. The study group included men aged 20–50, 33.1 ± 7.5. A total of 40 (50%) of the subjects comprised the physically active group (AG)—subjects doing wheelchair sport twice a week for 90 min a day. The physically inactive group (IG) comprised 40 (50%) subjects who had not participated in any sports activities. Statistical analyses were carried out using Shapiro-Wilk W-test and Mann-Whitney U test. Results. Significant differences were found between the physically active and inactive men with regard to their functionality status. The biggest differences were found for turning over (p < 0.001) and in adopting a sitting position (p < 0.001). Persons in the AG group had better results in all assessed activities. The biggest differences were observed in the field of toilet and dressing up: tooth-brushing p < 0.007 and washing the top part of the body p < 0.002. Conclusions. People participating in regular physical activity–wheelchair rugby–after spinal cord injury have a better relationship with better fitness, greater independence and a better functional status.
Morphological and Morphometrical Analysis of Mitral Valve in Maharashtra Region: Cadaveric Study

Mitral valve, Mitral valve prolapse (MVP), Papillary muscle, Chordae tendinae ABSTRACT Though many reports describe the morphometrical value of mitral valve for performing valve replacement surgeries, it is found that they vary from individual to individual. Total 30 cadaveric hearts were included in the present study. The mitral leaflet was dissected out. The opened out valves were then pinned to white thermocol sheet. Measurements were noted and statistically analyzed. The average measurements of annular circumference was 9.34cm. The average length of anterior leaflet was noted as 2.16cm & posterior leaflet 1.75cm. The average length of Chordae tendinae from apex of the anterior leaflet to the tip of anterior papillary muscle was 1.99cm & from apex of the posterior leaflet to the tip of posterior Papillary muscle was 2.14cm. This data provides interest to anatomists and cardiac surgeons about the knowledge of measurement of the mitral valve which help them to rule out normal and abnormal measurement.
Comparison of Pressure Sensing Properties of Carbon Nanotubes and Carbon Black Polymer Composites

Polymer composites containing conductive fillers that utilize the piezoresistive effect can be employed in flexible pressure sensors. Depending on the filler used, different characteristics of a pressure sensor such as repeatability, sensitivity, and hysteresis can be determined. To confirm the variation of the pressure sensing tendency in accordance with the dimensions of the filler, carbon black (CB) and carbon nanotubes (CNTs) were used as representative 0-dimension and 1-dimension conductive fillers, respectively. The piezoresistive effect was exploited to analyze the process of resistance change according to pressure using CB/PDMS (polydimethylsiloxane) and CNT/PDMS composites. The electrical characteristics observed for each filler were confirmed to be in accordance with its content. The pressure sensitivity of each composite was optimized, and the pressure-sensing mechanism that explains the difference in sensitivity is presented. Through repeated compression experiments, the hysteresis and repeatability of the pressure-sensing properties were examined.
Chemical Characterization of Flowers and Leaf Extracts Obtained from Turnera subulata and Their Immunomodulatory Effect on LPS-Activated RAW 264.7 Macrophages

The anti-inflammatory properties of Turnera subulata have been evaluated as an alternative drug approach to treating several inflammatory processes. Accordingly, in this study, aqueous and hydroalcoholic extracts of T. subulata flowers and leaves were analyzed regarding their phytocomposition by ultrafast liquid chromatography coupled to mass spectrometry, and their anti-inflammatory properties were assessed by an in vitro inflammation model, using LPS-stimulated RAW-264.7 macrophages. The phytochemical profile indicated vitexin-2-O-rhamnoside as an important constituent in both extracts, while methoxyisoflavones, some bulky amino acids (e.g., tryptophan, tyrosine, phenylalanine), pheophorbides, and octadecatrienoic, stearidonic, and ferulic acids were detected in hydroalcoholic extracts. The extracts displayed the ability to modulate the in vitro inflammatory response by altering the secretion of proinflammatory (TNF-α, IL-1β, and IL-6) and anti-inflammatory (IL-10) cytokines and inhibiting the PGE-2 and NO production. Overall, for the first time, putative compounds from T. subulata flowers and leaves were characterized, which can modulate the inflammatory process. Therefore, the data highlight this plant as an option to obtain extracts for phytotherapic formulations to treat and/or prevent chronic diseases.
