IoT System for the Continuous Electrical and Environmental Monitoring into Mexican Social Housing Evaluated under Tropical Climate Conditions

This work presented the design, development, and implementation of a low-cost IoT system for real-time monitoring of electrical consumption and environment parameters inside social housing. The IoT monitoring system is composed of a set of remote measurement nodes that wirelessly sense and transmit records of the air temperature and relative humidity inside the house as well as the voltage, current, and power consumed by several electrical devices. A server coordinator composed of a Raspberry Pi was used for the interaction with the sensors through the Message Queue Telemetry Transport (MQTT) protocol and allowed the measured data packaging, fragmentation, transfer, storage, and cloud upload for remote multiuser visualization. The system was experimentally evaluated in an inhabited single-story house under tropical climate conditions. Operation tests indicate a successful performance of the protocols implemented for remote visualization and cloud storage. Moreover, an analysis of measured data allows the feasibility of identifying the occupants’ energy consumption patterns and their relationship with the search for comfortable environmental conditions. Thus, the proposed friendly framework is a promising alternative to energy management. Its implementation in embedded Linux-based systems provides the flexibility to integrate control strategies based on artificial intelligence.
Thermal Kinetics of Monocationic and Dicationic Pyrrolidinium-Based Ionic Liquids

This work presents an in-depth kinetic thermal degradation comparison between traditional monocationic and the newly developed dicationic ionic liquid (IL), both coupled with a bromide (Br−) anion by using non-isothermal thermogravimetric analysis. Thermal analyses of 1-butyl-1-methylpyrrolidinium bromide [C4MPyr][Br] and 1,4-bis(1-methylpyrrolidinium-1-yl)butane dibromide [BisC4MPyr][Br2] were conducted at a temperature range of 50–650 °C and subjected to various heating rates, which are 5, 10, 15, 20 and 25 °C/min. Thermogravimetric analysis revealed that dicationic IL, [BisC4MPyr][Br2] is less thermally stable compared to monocationic [C4MPyr][Br]. A detailed analysis of kinetic parameters, which are the activation energy (Ea) and pre-exponential factor (log A), was calculated by using Kissinger-Akahira-Sunose (KAS), Flynn-Wall-Ozawa (FWO) and Starink. This study revealed that the average Ea and log A of [BisC4MPyr][Br2] are lower than [C4MPyr][Br], which may be contributed to by its low thermal stability. Conclusively, it proved that the Ea and log A of ILs are strongly related to the thermal stability of ILs.
Is it time to rethink our one-size-fits-all approach to nitrate toxicity thresholds in forages?

Abstract Annual forages provide a valuable grazing resource for cattle producers; however, annuals are prone to accumulating nitrate and have the potential to cause nitrate toxicity. Although these forages pose a risk of containing high nitrate concentrations, they can be a high-quality feed source. Understanding the factors that affect the potential for toxicity when using these forages is important to help nutritionists and producers make management decisions. This review describes the previous research, current guidelines for nitrate toxicity, and the potential for improvement in our current recommendations. Current extension toxicity guidelines appear to be founded primarily on drenching based studies and overestimate the nitrate toxicity potential of forages. Recommendations need to account for multiple factors that affect the threshold for toxicity. There is evidence that fresh forages have a lower risk of toxicity because of slower release of nitrate into the rumen and a slower rate of dry matter intake. Increased dietary energy and sulfur content reduce the potential for toxicity. Microbial adaptation can reduce the risk and allow use of potentially toxic forages. These factors should influence feeding recommendations. However, there is currently not enough data available to establish new guidelines that account for these main factors. Thus, there is a need for renewed research in this area. The limited number of studies grazing elevated nitrate forages seems to suggest that there is less risk in grazing situations, especially if animals graze selectively. There is a need to develop guidelines for nitrate toxicity and management recommendations when grazing. To accomplish this, there is a need for more studies to evaluate risk of toxicity in grazing situations. These grazing studies need to evaluate the effects of nitrate concentration, forage quality, and grazing management on the potential for nitrate toxicity. While the conservative guidelines that are currently in use reduce risk of nitrate toxicity, they may also cause a significant increase in feed costs for producers.
The innovation and its territorial factors: An analysis in the micro-regions of SÃ£o Paulo

This paper aims to examine empirically, through the application of the Knowledge Production Function, how the innovation in micro-region of SA£o Paulo can be affected for some territorial factors. In the literature, and assumed here, the innovative results, measured by patents, are linked to the quantity and quality of innovative inputs and characteristics of the regions that are configured as an input. In this sense, stands the importance of positive externalities that are generated by the spatial concentration of producers and support institutions that are able to contribute to the efforts of innovative firms. In addition, this paper emphasizes the role of local production structures in the regions of SA£o Paulo, since both the regional diversification and regional specialization are mentioned as important factors in the innovation process. The main results suggested that although the level of R&D investments were important for generating local innovation, ie, the generation of local patents, this relationship does not occur clearly in the regions of SA£o Paulo. In addition, local productive structure or density linkages of firms that interacts are certainly important factors and compensatory for innovation process.
Use of later lactation records in dairy cattle breeding

A multivariate restricted maximum likelihood procedure was used to estimate variance and covariance components between and within sires. Considering all lactations simultaneously, this method accounted for the bias in later lactation records due to selection on dairy performance. Analysis was carried out for a mixed model with herd-year-seasons as fixed and sires as random effects and fitting lactation length, calving age and month within season of calving as covariables. Data were analysed in 13 subsets including. 26176 first, 19978 second and 14868 third lactation records for 679 test sires. Additional records for proven sires, treated as fixed effects, were included to improve the data structure. Estimates for all components were higher in later than in earlier data sets, probably to a large extent on account of a scale effect. Pooled estimates of heritabilities for lactations one to three were 0.28, 0.19 and 0.24 for milk yield and 0.27, 0.21 and 0.25 for fat yield. Genetic correlations of 0.91, 0.91 and 0.95 for milk yield and 0.91, 0.91 and 0.99 for fat yield were found between lactations one and two, one and three and two and three, respectively. Results suggest that dairy performance in all lactations is genetically almost identical.
Digitally Outsourced: The Limitations of Computer-Mediated Transparency

The introduction of digital communication technologies has resulted in the emergence of transparency as a journalistic norm. Often termed the “new objectivity,” transparency has been viewed as central to restoring trust in journalism. Not surprisingly, news organizations have claimed they have introduced transparency measures that enable audiences to look behind the curtain of news production. We, however, argue that such efforts primarily involve technological features that are institutionally mandated with little involvement from journalists. That is, transparency in journalism has been digitally outsourced to technology, a development that disconnects journalists from considering and implementing transparency in their work.
A Robot in a Shopping Mall that Affectively Guide Customers

This paper describes the development of a guide robot for a shopping center, which attempts to build rapport with customers while providing route guidance and other shopping information. A field trial was conducted at a shopping mall for 25 days to study the possible role of a robot in a shopping center. Since a shopping center is a place where local people repeatedly visit, it is important for the robot to interact with people multiple times. Using passive RFID tags to identify customers, and using the WOZ method to overcome difficulties in speech recognition, the robot built rapport with customers through a series of interactions based on a set of four design principles. During each day of the field trial, the robot interacted with approximately 200 customers, and the robot was able to sustain customers' interest throughout multiple interactions. The robot also provided shopping information through natural conversation with the customers, and the experimental results revealed that 63 out of 235 people in fact went shopping based on advice from the robot. These results seem to demonstrate a promising potential for guide robots designed to build rapport with customers in a shopping mall.
Effectiveness of Wastewater Treatment Installation and Liquid Waste Quality in Dr. Soetomo General Hospital, Surabaya

Introduction: Hospitals are institutions that produce liquid waste that may pollute the environment and have a dangerous impact on health. Hospital waste has the potential to contain hazardous chemicals, pharmaceutical waste, radioactivity and microbiological pathogens in liquid waste that can pollute the environment and disrupt the balance of the ecosystem. This study aims to determine the effectiveness of the Wastewater Treatment Plant (WWTP) and the quality of the liquid waste at the Dr. Soetomo General Hospital. Methods: This research was a quantitative descriptive study using secondary data from laboratory analysis of wastewater inlet and outlet of The Central Wastewater Treatment Plant (WWTP) of Dr. Soetomo General Hospital for the January-December 2020 period. Effectiveness was obtained by calculating the difference between the inlet and outlet values of each parameter divided by the inlet value multiplied by 100%. Results and Discussion: WWTP in Dr. Soetomo General Hospital Surabaya used a central WWTP which had 3 (three) units, namely WWTP Sequence Batch Reactor (SBR), WWTP Membrane Biostrain Reactor (MBR) and WWTP Aerobic Biofilter which aims to improve the quality of liquid waste. Based on the results of the research analysis, it has been found that hospital wastewater treatment using a central WWTP system is effective for reducing the levels of parameters, namely Total Suspended Solid (TSS) by 60.55%, Biological Oxygen Demand (BOD) by 72.52%, Chemical Oxygen Demand (COD) by 54.02%, Ammoniacal Nitrogen (NH3N) by 90.91%, Phospate (PO4) by 71.43%, bacteria group E. Coli by 99.93%. The temperature and Potential of Hydrogen (pH) parameters recorded at the outlet are in accordance with the established quality standards. Conclusion: The three WWTP units used in Dr. Soetomo General Hospital are able to treat liquid waste effectively. Liquid waste at each outlet parameter is in accordance with East Java Governor Regulation No. 72 of 2013 concerning quality standards for health facilities waste water, so that the effects of contamination on the environment can be minimized.
Online lab design for aviation engineering students in higher education: a pilot study

ABSTRACT There is a strong need for educators to change the way they conduct aviation education to bring up future professionals in the industry. To cope with the COVID-19 challenge, creative online distance learning approaches become necessary. This article shows how an online lab approach offers social and cognitive support for engineering students to sustain their learning. A series of learning activities including flight simulation and virtual tours were held in an online lab setting by aviation professionals and lecturers at a university in Hong Kong to 35 undergraduate engineering students. The online lab encouraged students to apply knowledge into practice and develop their theoretical and conceptual knowledge through activities. Workshops focusing on aviation laboratory education aimed at students’ development of aviation theoretical and technical knowledge, collaborative skills, field-specific, and practical skills. A mixed research method was employed with the use of a motivational survey, teachers’ observation, and semi-structured interviews to understand students’ learning perceptions. This study found that the online laboratory activities could effectively motivate students to learn about aviation and improve their aviation knowledge cognitively and socially. It is recommended for online engineering educators to use lab technologies to teach aviation and related disciplines for future career preparation.
A High-Resolution Acoustic Imaging System to Map Interior Fish Morphology

An acoustic imaging microtome system (AIMS) was constructed to map the internalstructureof fish.Thesystemconsistsoftwo pairs ofhigh-frequency(4.5MHz) transmit-and-receive planar arrays, with one pair in the vertical plane and the other in the horizontal plane. AIMS provides a series of acoustic images, analogous to microtome slices, along the length of a fish by combining electronically controlled sequentialacoustictransmissionsandreceptionsover224channelsandacomputercontrolled mechanical device that moves the acoustic arrays lengthwise along the fish. AIMS measures the acoustic attenuation (extinction) along the direct ray paths of each transmit-receive channel pair that penetrates the fish body in a bistatic configuration. This results in a 2-D image of the interior morphology with 4- to 5-mm resolution. The images can provide morphological information on the fish’s cheekbone, backbone, rib bone, skull, fins, stomach, and swimbladder, which is important for accurately modeling fish acoustic target strength, especially for non-swimbladderbearing fish species.
Online Database of Multiwavelength Water Masers in Galactic Star-forming Regions

In this paper, we present an online multiwavelength database of water masers in star-forming regions of the Galaxy. The collected data represent ∼95% of all observations of water masers in star-forming regions published since 1989. Nineteen transitions are included, from 22 GHz to 1.88 THz. The MaserDB.net information system provides fast and open access to the collected data, including maser tabular data, spectra, and interferometric maser spot data. The database covers ∼18,700 individual observations and ∼7200 maser detections. The data on the water maser detection are available for ∼2600 sources, and interferometric data are available for ∼560 sources. Statistical analysis of the water masers’ data and comparison with other abundant maser species found in star-forming regions (OH and CH3OH of class I and II) show that water masers are the most ubiquitous maser type. Access to the water maser database is available online at https://MaserDB.net. The database can be queried using a web search form or Structured Query Language.
Insecticide resistance in Australian Spodoptera frugiperda (J.E. Smith) and development of testing procedures for resistance surveillance

Spodoptera frugiperda (J.E. Smith) is a highly invasive noctuid pest first reported in northern Australia during early 2020. To document current status of resistance in S. frugiperda in Australia, insecticide toxicity was tested in field populations collected during the first year of establishment, between March 2020 and March 2021. Dose-response was measured by larval bioassay in 11 populations of S. frugiperda and a susceptible laboratory strain of Helicoverpa armigera. Emamectin benzoate was the most efficacious insecticide (LC50 0.023μg/ml) followed by chlorantraniliprole (LC50 0.055μg/ml), spinetoram (LC50 0.098μg/ml), spinosad (LC50 0.526μg/ml), and methoxyfenozide (1.413μg/ml). Indoxacarb was the least toxic selective insecticide on S. frugiperda (LC50 3.789μg/ml). Emamectin benzoate, chlorantraniliprole and methoxyfenozide were 2- to 7-fold less toxic on S. frugiperda compared with H. armigera while spinosyns were equally toxic on both species. Indoxacarb was 28-fold less toxic on S. frugiperda compared with H. armigera. There was decreased sensitivity to Group 1 insecticides and synthetic pyrethroids in S. frugiperda compared with H. armigera: toxicity was reduced up to 11-fold for methomyl, 56 to 199-fold for cyhalothrin, and 44 to 132-fold for alpha cypermethrin. Synergism bioassays with metabolic inhibitors suggest involvement of mixed function oxidase in pyrethroid resistance. Recommended diagnostic doses for emamectin benzoate, chlorantraniliprole, spinetoram, spinosad, methoxyfenozide and indoxacarb are 0.19, 1.0, 0.75, 6, 12 and 48μg/μl, respectively.
The Baby's First Bites RCT: Evaluating a Vegetable-Exposure and a Sensitive-Feeding Intervention in Terms of Child Health Outcomes and Maternal Feeding Behavior During Toddlerhood

ABSTRACT Background Parenting interventions during the first years of life on what and/or how to feed infants during complementary feeding can promote healthy eating habits. Objectives An intervention promoting repeated exposure to a variety of vegetables [repeated vegetable exposure (RVE); what] and an intervention promoting responding sensitively to child signals during mealtime [video-feedback intervention to promote positive parenting–feeding infants (VIPP-FI); how] were compared, separately and combined (COMBI), with an attention control condition (AC). Primary outcomes were vegetable consumption and self-regulation of energy intake; secondary outcomes were child anthropometrics and maternal feeding practices (sensitive feeding, pressure to eat). Methods Our 4-arm randomized controlled trial included 246 first-time Dutch mothers and their infants. Interventions started when infants were 4–6 mo old and ended at age 16 mo. The present study evaluated effects at 18 (t18) and 24 (t24) mo of age. Vegetable acceptance was assessed using three 24-h dietary recalls, self-regulation of energy intake by an eating-in-the-absence-of-hunger experiment and mother-report, and maternal feeding behavior by observation and mother-report. Results Linear mixed model and ANOVA analyses revealed no follow-up group differences regarding child vegetable intake or self-regulatory behavior. The proportion of children with overweight was significantly lower in the COMBI group, compared with the VIPP-FI group at t18 (2% compared with 16%), and with the AC group at t24 (7% compared with 20%), although this finding needs to be interpreted cautiously due to the small number of infants with overweight and nonsignificant effects on the continuous BMI z-score measure (P values: 0.29–0.82). Finally, more sensitive feeding behavior and less pressure to eat was found in the VIPP-FI and COMBI groups, compared with the RVE and AC groups, mostly at t18 (significant effect sizes: d = 0.23–0.64). Conclusions Interventions were not effective in increasing vegetable intake or self-regulation of energy intake. Future research might usefully focus on risk groups such as families who already experience problems around feeding. This trial is registered at clinicaltrials.gov as NCT03348176.
Creating a social movement to engage communities in physical activity: A mixed methods study of motivations to engagement

Throughout the world social isolation and loneliness are common and both have several adverse impacts on health and wellbeing. We are designed to live in close-knit communities and we thrive in close co-operation, however, modern life isolates us from others. To reduce the burden of loneliness and social isolation we need to find strategies to reconnect people to each other, their place and provide a common purpose. Social movements aim to create healthier communities by connecting people to each other and giving people a common purpose. Interventions which create a social movement appear to be effective at engaging substantial portions of a community, however, it remains unclear why individuals are attracted to these initiatives, and if such reasons differ by sociodemographic characteristics. This study combined qualitative and quantitative methods to understand what motivated (different) people to take part in a social movement based intervention. This study suggests that it is not one but a combination of reasons people engage in interventions of this nature. This diversity needs to be acknowledged when promoting and communicating these interventions to potential participants to maximise engagement. Promoting an end reward or health/fitness may not be the most effective way to promote interventions to a large proportion of people. Instead, communications should be centred around what people value (i.e., being with their friends, doing what they enjoy and are good at).
ADP-ribosylation factor 6 expression increase in oesophageal adenocarcinoma suggests a potential biomarker role for it

ADP-ribosylation factor 6 small GTPase plays an important role in cell migration, invasion and angiogenesis, which are the hallmarks of cancer. Although alterations in ARF6 expression and activity have been linked to metastatic cancer in one or two tissues, the expression of ARF6 in cancers over a wide range of tissues has not been studied so far. In this report, we analysed the expression of ARF6 mRNA in cancers and corresponding healthy controls from 17 different tissues by real-time qualitative polymerase chain reaction (RT-qPCR). We further evaluated ARF6 protein expression in oesophageal adenocarcinoma (EAC) tissue microarray cores by immunohistochemistry. The ARF6 gene expression levels are highly variable between healthy and cancer tissues. Our findings suggest that the ARF6 gene expression is up-regulated highest in oesophageal cancer. In EAC TMAs, ARF6 protein expression increase correlated with EAC progression. This is the first study to investigate ARF6 gene expression in a wide array of cancer tissues and demonstrate that ARF6 expression, at both mRNA and protein levels, is significantly upregulated in higher grades of EAC, which may be useful in targeting ARF6 for cancer diagnostic and therapeutic purposes.
Application of EMD Noise Reduction and Wavelet Transform in Bearing Fault Diagnosis

In order to reduce the interference of noise on the wavelet transform in bearing fault diagnosis,the comprehensive method that firstly using Empirical Mode Decomposition(EMD) and then analyzing the signal with the wavelet transform is put forward.Based on signal decomposition by EMD self-adaption,the intrinsic mode functions of kurtosis value with preferably high contribution is selected to reconstruct signal from autocorrelation noise reduction and then conduct the wavelet transform to obtain the cascade spectrum of decomposed detailed signals as well as the best-performing component Hilbert demodulation.It solves the problem that the interference of the noise on the weak fault signal results in the obscure diagnosis effect,and improves the fault identification rate and efficiency of wavelet transform.The bearing rollers pitting failure test shows: this method can effectively extract the rolling bearing fault features,and has better results compared with the traditional envelope demodulation.
