Effect of VP, MAP and combined packaging systems on the physicochemical properties and microbiological status of veal from unweaned calves

The packaging system is one of the factors influencing the preservation of the nutritional value, microbiological safety, and sensory attributes of meat. The study investigated changes in physicochemical and microbiological properties taking place during 15-day refrigerated storage of two calf muscles, the longissimus lumborum (LL) and semitendinosus (ST), packaged in three systems, respectively, vacuum packing (VP), modified atmosphere packaging (MAP, 80% O2 + 20% CO2), and a combined system (VP + MAP, 8 d in VP followed by 7 d in MAP). LL and ST stored in VP had significantly lower levels of lipid oxidation, higher α-tocopherol content, and higher instrumentally measured tenderness in comparison with the samples stored in MAP. On the other hand, the MAP samples had lower purge loss at 5 and 15 days, a higher proportion of oxymyoglobin up to 10 days of storage, and a better microbiological status. Calf muscle samples stored in the VP + MAP system had intermediate values for TBARS and α-tocopherol content and at the same time were the most tender and had the lowest counts of Pseudomonas and Enterobacteriaceae bacteria at 15 days. All packaging systems ensured relatively good quality of veal characteristics up to the last day of storage. However, for MAP at 15 days of storage, unfavourable changes in colour (a high level of metmyoglobin and a decrease in oxymyoglobin, redness and R630/580 ratio) and in the lipid fraction (a high TBARS value and a significant decrease in α-tocopherol content) were observed.

Development of the Anthropomorphic Arm for Collaborative and Home Service Robot CHARMIE

Service robots are rapidly transitioning from concept to reality, making significant strides in development. Similarly, the field of prosthetics is evolving at an impressive pace, with both areas now being highly relevant in the industry. Advancements in these fields are continually pushing the boundaries of what is possible, leading to the increasing creation of individual arm and hand prosthetics, either as standalone units or combined packages. This trend is driven by the rise of advanced collaborative robots that seamlessly integrate with human counterparts in real-world applications. This paper presents an open-source, 3D-printed robotic arm that has been assembled and programmed using two distinct approaches. The first approach involves controlling the hand via teleoperation, utilizing a camera and machine learning-based hand pose estimation. This method details the programming techniques and processes required to capture data from the camera and convert it into hardware signals. The second approach employs kinematic control using the Denavit-Hartenbergmethod to define motion and determine the position of the end effector in 3D space. Additionally, this work discusses the assembly and modifications made to the arm and hand to create a cost-effective and practical solution. Typically, implementing teleoperation requires numerous sensors and cameras to ensure smooth and successful operation. This paper explores methods enabled by artificial intelligence (AI) that reduce the need for extensive sensor arrays and equipment. It investigates how AI-generated data can be translated into tangible hardware applications across various fields. The advancements in computer vision, combined with AI capable of accurately predicting poses, have the potential to revolutionize the way we control and interact with the world around us.

Impact of silicon-enriched plant biostimulant treatment on shelf-life of baby spinach (Spinacia oleracea) crops

This research presents the findings from a series of experiments to assess and quantify the influence of compostable plastic packaging in combination with silicon biostimulant on waste produced in a typical leafy horticultural product. The research was conducted firstly by using an agricultural biostimulant consisting in varying supplementation with monosilicic acid, performed in 16 blocks with 3 different treatments and compared against the control samples. In addition, Equilibrium Modified Atmosphere Packaging (EMAP) packaging was designed using polypropylene (OPP) and compostable polylactic acid (PLA) films in order to assess the effect of potential mitigation of food waste production in combination with sustainable films. Storage studies were conducted to assess the amount of product that would run out of specification across a usability period of 7 days as an estimation of waste. The results show that 1 % waste was produced with OPP and no-mitigation, experiments showed a potential waste of 26 % using compostable films. The silicon-based supplementation managed to reduce waste by an average of 35 % in the case of the use with PLA. The results of this study establish a potential pathway for transition towards sustainable films in short shelf-life horticultural products using bio-stimulants with controlled dependents on EMAP.

Nonpharmacological interventions and outcomes in the management of complications of human T-cell lymphotropic virus type 1-related myelopathy/tropical spastic paraparesis: A systematic review.

Human T-cell lymph tropic virus type 1 (HTLV-I)-related myelopathy/tropical spastic paraparesis (TSP) is a progressive inflammatory process affecting the spinal cord that occurs as a result of HTLV 1. The use of nonpharmacological approaches has always been one of the treatment strategies in these patients, but disagreement about these interventions and their results has led to their limited use. Therefore, this study aimed to identify nonpharmacological interventions and their consequences in these patients. We followed the Cochrane Handbook for systematic reviews of interventions. The present report is organized according to the preferred reporting items for systematic reviews and meta-analyses. This study was conducted at PubMed, Cochrane Library, Web of Science, and Scopus, among all published studies by December 30, 2021. Keywords were: HTLV-1, Human T-lymph tropic virus 1, HTLV-I-associated myelopathy, HAM/TSP, tropical spastic paraparesis, nonpharmacological intervention, nonpharmacological treatment, massage, physiotherapy, acupuncture, acupressure, and exercise. The quality of the studies was assessed using JADAD. Of 288 articles, 11 were eligible for data extraction published between 2014 and 2021. 90/9% of studies were randomized clinical trials. 81/8% of articles were of high quality. The total sample size was 253 people, of which 137 (54/15%) were women. Approaches such as exercise and motion therapy, electrotherapy, behavioral therapy, and virtual reality can be used for these patients. With these interventions, results such as improved mobility and balance, physical condition, pain, quality of life, muscle spasticity, maximum inspiratory pressure, and urinary symptoms can be achieved. The most common physical therapy method used in studies was active and passive body movements, which are associated with positive results for patients. Due to the small sample size in this group of studies, it is necessary to conduct more clinical trials for more accurate conclusions. Furthermore, due to the limited number of studies that have used electrical stimulation or combined intervention packages, it is not possible to say with certainty what effect these methods have on patients. It is necessary to conduct more clinical trials.

Benefits assessment of cool skin and ventilated cavity skin: Saving energy and mitigating heat and grid stress

This study assessed the energy-saving and climate-adaptive potential of cool skin and ventilated cavity skin facade technologies in Seoul's high-rise apartment buildings. We created weather scenarios for historical, mid-term future, and long-term future conditions using Coordinated Regional Downscaling EXperiment (CORDEX) method. Building energy simulations were conducted on a South Korean high-rise apartment model to evaluate their performance under different weather conditions. The results indicate that cool skin and ventilated cavity skin technologies can save cooling energy during summers but lead to heating energy penalties in winters. Ventilated cavity skin outperforms cool skin, offering better cooling energy savings and reduced heating penalties. Combining both technologies yields the highest overall energy savings, with 7 %, 9 %, and 10 % cooling energy savings for cool skin, ventilated cavity skin, and the combined package, respectively. However, cool skin increases heating energy consumption by 5 %, while ventilated cavity skin has minimal impact on heating energy. These envelope technologies also reduce peak electricity demand by at least 5 %, 8 %, and 9 %, respectively. They contribute to heat stress reduction, enhance resilience, and decrease extreme heat risks for occupants during power outages by at least 18 % under various weather conditions. Considering the prevalence of aging high-rise apartments in South Korea, adopting these envelope renovation strategies can effectively reduce cooling loads, enhance thermal comfort, and boost resilience under future climates, while avoiding costly reconstruction.

A 256 channel photon counting module using a square microchannel plate PMT in a tight packing envelop achieving

Photek have developed a square microchannel plate (MCP) photomultiplier tube (PMT) using 6 μm pore MCPs to achieve superior timing, compared to the previous generation which used 15 μm pores. The native anode pattern is 64 × 64, but for this module the pattern is ganged to a 16 × 16 design using an epoxy bonded PCB giving an anode size of 3.3 × 3.3 mm in a 53 × 53 mm active area. The electronic front-end is the TOFPET2d ASIC from Petsys Electronics, a combined amplifier/discriminator/TDC with 30 ps time bins and capable of 480 kHz per channel count rate, with sufficient dynamic range to allow for the gain variation inherent in large area MCP-PMTs. The outer envelope of the combined PMT and electronic front-end package allows for close packing on 4 sides with outer dimensions of 60 × 62 mm giving a 76% fill factor. We present results showing the combined performance of the PMT and TOFPET2d ASIC and the uniformity of single photon timing accuracy.

Fresh product e-retailer’s sales strategy choice: free shipping, package, or combined strategy?

Cold chain technology and online platform have enabled the rapid development of fresh food e-commerce. However, most fresh product e-retailers are losing money. This paper aims to answer the questions: Can the free shipping strategy, package strategy, and combined package and free shipping strategy (i.e., KF strategy) improve a fresh product e-retailer’s performance, and which strategy is the most effective? By deriving the optimal decisions of customers and/or the e-retailer under different strategies, we find that the e-retailer should adopt the free shipping strategy or the KF strategy if the shipping cost is higher than the threshold. Furthermore, some managerial insights are obtained. First, compared with the general strategy, the e-retailer needs to further reduce the price when the shipping cost is lower than the threshold despite bearing the shipping cost under the free shipping strategy or KF strategy. Second, the free shipping strategy or KF strategy is generally used to increase the customer’s single order quantity. However, if the shipping cost is higher than the threshold, the e-retailer should use these two strategies to reduce the single order quantity. Lastly, if the e-retailer wants to reduce its average logistics cost, the package strategy is a better choice.

Evaluation of Experience-Driven Career Support Services for NEET Youth in Community Contexts

Informed by three interlocking perspectives, namely, recognition theory, psychosocial resources, and the expanded notion of work, this study evaluated the effectiveness of a career support service project characterized by experience-driven interventions on reengaging a diverse group of youth aged 15–21, who were not in education, employment or training (NEET) in community contexts and on enhancing their psychosocial resources. The results of repeated measures analysis of variance (ANOVA) showed significant pre- and post-intervention changes of 660 NEET participants in relation to their psychosocial resources encompassing career adaptability, social support and career engagement. All participants reported that they successfully achieved status-based and/or non-status-based recognition over three to six months after case closure. The results of multivariate analysis of covariance (MANCOVA) further revealed that the four categories of interventions provided by the project significantly influenced the participants’ composite psychosocial resources when controlling for their gender, educational attainment, length of duration as NEET, presenting problems, and pre-intervention scores. Moreover, the combined package of interest development plus career counseling and guidance ranked the most effective intervention. This study sheds light on developing career support services for NEET youth in diverse community contexts.

Качество и безопасность продукции в процессе хранения в системе «вино – упаковка, укупорка»

Poor packaging often affects the quality and safety indicators of wine during storage. The need to preserve and prolong wine stability during long-term storage requires a comprehensive study of processes that occur in wines packaged and capped in various ways.
 This research featured 56 samples of white and red dry wines, which were bottled in four types of packages and stopper for 18 months. The effect of synthetic and natural stopper methods involved a model system that simulated the main composition of wine in line with the EAEU standards. The contents of free SO2 and dissolved oxygen, as well as the microbiology of natural corks, were studied using standard methods. The analysis of volatile substances relied on gas chromatography, mass spectrometry, and solid phase micro-extraction.
 The study recorded critical changes in the quality of wine products, characterized by increased oxidation markers and low free sulfur dioxide, which fell below 10 mg/dm3. In polyethylene terephthalate bottles, these changes occurred after 12 months of storage, while it took them 18 months to develop in multilayer bags and combined packaging materials. The components of natural and artificial plugs of microbial and chemical origin entered the model systems after 10 days of contact. The microbiological contamination was twice as high as the permissible level. The migration of microbial and chemical substances into the wine samples spoiled their quality and safety.
 The effect of packaging on the oxidative processes in white and red dry wines during storage resulted in different concentrations of dissolved oxygen and sulfur dioxide. The results can help wine producers to choose the most appropriate packaging and stopper means depending on the wine sort and its subsequent storage conditions. Alternative types of packaging proved to have a limited shelf life.

Estimation of vegetable leather shelf life from a combination of beluntas leaves (Pluchea indica L.) and seaweed (Eucheuma cottonii) with various types of packaging using the ASLT (accelerated shelf life testing) method of the arrhenius model

Beluntas leaves vegetable leather is a new processed product, so its shelf life is currently unknown. This research utilised the ASLT (Accelerated Shelf Life Test) Arrhenius model to assess the shelf life of vegetable leather in three different forms of packaging, including aluminum foil, combination (aluminum foil-polyethylene), and polypropylene. The research includes two replications and a descriptive design. Three different types of packing were used to store vegetable leather for a month at oven temperatures of 30°C, 35°C, and 40°C (28 days). Every week, on days 0, 7, 14, 21, and 28, observations were made about the moisture content and sensory factors (texture, color, and aroma). The shelf life of vegetable leather was calculated using the parameter data using the Arrhenius model ASLT method with Microsoft Excel 2010. The results indicated that vegetable leather beluntas leaves packaged in aluminum foil had a shelf life of 179.53 days (5 months, 27 days), while in combination packaging (aluminum foil-polyethylene), they had a shelf life of 44.20 days (1 month, 13 days). In polypropylene packaging, the product had a shelf life of 35.94 days (1 month and four days) according to order 1 of the Arrhenius model ASLT method.

Review of packaging for improving storage quality of fresh edible mushrooms

AbstractEdible mushrooms are favoured by people for their rich nutrition, medicinal value and unique flavour. The quality of postharvest mushroom decreased sharply because of its special tissue structure and physiological characteristics. Compared with other preservation technologies, packaging has been widely used in the preservation of mushrooms because of its strong preservation effect, green and convenient characteristic. This review discussed the quality deterioration of fresh mushrooms and its influencing factors, and summarised the research advances and preservation mechanism of modified atmosphere packaging (MAP), active packaging (ACP), biodegradable film packaging (BFP) and nanocomposite packaging (NCP) used to cope with the quality deterioration of fresh mushrooms. The packaging mainly maintains the quality of mushrooms and extends their shelf life by exerting antibacterial, antiviral and antioxidant, and by regulating respiration and energy metabolism, cell wall metabolism and membrane lipid metabolism. Currently, the combined packaging based on nano, active and biodegradable is getting more attention, but there is a lack of in‐depth genetic research on its preservation mechanism. Nanoemulsion‐based packaging was used in many foods; however, there is little research on the preservation of mushrooms. Based on the above packaging, the next step is to explore the intelligent packaging for edible mushrooms. This review can provide reference for further research and application of packaging preservation in mushrooms, to improve the quality of postharvest mushrooms.

The effects of digital servitization on business competitiveness: A case study of Spanish manufacturers

In recent years, interest has grown in servitization strategies as business models for selling combined packages of goods and services to create competitive advantage to provide great customer value. Various studies have examined the benefits servitization offers to both businesses and their customers; however, there is very little research on the moderating role played by the digital enablers of Industry 4.0 on servitization. It is this research gap that the present study aims to fill. Using a framework developed from the extant literature, case studies, with an exploratory objective, were conducted to the aim of identifying and analyzing the challenges and opportunities that could be presented in those companies that decide to develop digital servitization. To achieve it, this study focuses on a deep analysis of the experience in five manufacturing companies, and, from that, we draw significant conclusions (both for further research and for business practice) about the strategy of servitization and the moderating role of Industry 4.0 on business competitiveness. We first carried out detailed interviews with key personnel from companies, complementing that with additional information from various sources before analyzing the results to identify emerging topics. The qualitative study allowed us to highlight how the different kinds of digital technologies supported servitization and product innovation. In addition, it provides empirical evidence about the different servitization strategies and Industry 4.0 digital enablers, which, in combination, allows companies achieving increased competitiveness, generate greater returns, find new customers, access new markets, and develop new business ideas.

Suubi + Adherence4Youth: a study protocol to optimize the Suubi Intervention for Adherence to HIV treatment for youth living with HIV in Uganda

BackgroundSuubi is an evidenced based multi-component intervention that targets psychosocial and economic hardships to improve ART adherence, viral suppression, mental health, family financial stability, and family cohesion for adolescents living with HIV (ALHIV) in Uganda. Suubi was originally tested as a combined package of four components: 1) Financial Literacy Training; 2) incentivized matched Youth Savings Accounts with income-generating activities; 3) a manualized and visual-based intervention for ART adherence and stigma reduction; and 4) engagement with HIV treatment-experienced role models. However, it is unknown if each component in Suubi had a positive effect, how the components interacted, or if fewer components could have produced equivalent effects. Hence, the overall goal of this new study is to identify the most impactful and sustainable economic and psychosocial components across 48 health clinics in Uganda.MethodsA total of 576 ALHIV (aged 11–17 years at enrollment) will be recruited from 48 clinics and each clinic will be randomized to one of 16 study conditions. Each condition represents every possible combination of the 4 components noted above. Assessments will be conducted at baseline, 12, 24, 36 and 48- months post-intervention initiation. Using the multi-phase optimization strategy (MOST), we will identify the optimal combination of components and associated costs for viral suppression, as well as test key mediators and moderators of the component-viral suppression relationship.DiscussionThe study is a shift in the paradigm of research to use new thinking to build/un-pack highly efficacious interventions that lead to new scientific knowledge in terms of understanding what drives an intervention’s success and how to iterate on them in ways that are more efficient, affordable and scalable. The study advances intervention science for HIV care outcomes globally.Trial RegistrationThis project was registered at clinicaltrials.gov (NCT05600621) on October, 31, 2022. https://clinicaltrials.gov/ct2/show/NCT05600621

Hyperspectral imaging combined with fluorescence for the prediction of microbial growth in chicken breasts under different packaging conditions

The crucial feature of chicken is real-time microbial growth detection along the supply chain. Hyperspectral imaging (HSI) is an online and nondestructive technique that is well suited to microorganism analysis applications. In this study, visible and near-infrared (Vis/NIR, 400–1000 nm) HSI were utilized to establish prediction models of the total viable count (TVC) of chicken breasts stored in vacuum, pallet, and combined packaging using partial least squares regression (PLSR) and support vector machine (SVM) after spectral pretreatments and optimal wavelength selection. The SVM algorithm was used to develop the best TVC prediction models for storage, with the following outcome: vacuum (R2p = 0.91, RMSEp = 0.47, RPD = 2.44), pallet (R2p = 0.90, RMSEp = 0.54, RPD = 2.32), and combined (R2p = 0.89, RMSEp = 0.58, RPD = 2.21) packs. Successively, HSI combined with fluorescence (F–HSI) was used to predict the TVC and coliforms of chicken breasts in combined packaging. Compared to HSI, F–HSI achieved the best-predicted results for TVC (R2p = 0.93, RMSEp = 0.44, RPD = 2.74) and coliforms (R2p = 0.92, RMSEp = 0.46, RPD = 2.57). These results indicated that fluorescence, as a complementary technique for HSI, will be widely used in the chicken supply chain to predict microbial growth.

Technological features of production high-quality packaging material with metallized paper for the food industry

Introduction The barrier properties of paper-based packaging may not be sufficient for long-term storage to ensure the quality and taste of packaged food products. All this requires researching the technological features and developing a combined packaging material in which the base paper is combined with polymer materials or a metallized coating is applied to its surface.
 Results and discussion Food products are very sensitive to the influence of external factors, so the barrier properties of paper-based packaging become insufficient for long-term storage to ensure the quality of food products and their taste properties. All this requires the development and mastery of the production of modern barrier combined packaging materials and conducting research on the development of requirements for base paper in order to obtain combined, namely: metallized packaging materials. As research results have shown, base paper should be characterized by high resistance to mechanical influences in the process of processing, as well as exploitation of the finished material. It should have a surface that provides optimal interaction with the foil, have high barrier and protective properties.
 In the process of carrying out research on the creation of a new combined package, the requirements for the metallized material and the quality of the base paper were determined. The index of smoothness of the surface of the base paper should not be lower than 150 s, and its moisture content should not exceed 4%, because its higher values, as experiments have shown, do not allow creating the necessary rarefaction in the chamber for metallization and ensuring the uniformity of metal application. In the case of spraying aluminum with increased residual humidity of the paper, intensive oxidation processes take place, which negatively affect the quality of the coating, its protective properties and the strength of adhesion (adhesion) to the surface of the substrate.
 As a result of the research, graphical dependences of the electrical resistance and opacity of the metallized material on the thickness of the coating were also obtained, which plays an important role in improving the protective, barrier and other properties of the packaging. Experimental data were also obtained that illustrate the influence of the speed of rewinding and the smoothness of the surface of the base paper in the process of metallization in a vacuum on the indicator of electrical resistance, which is an indirect characteristic of the thickness of the metallized coating of the material.
 The conducted studies of the new combined metallized packaging material also showed that the coating contributes to the improvement of the protective properties of the material and the tightness of the packaging, namely: reducing gas permeability, weakening the effect of optical radiation on products, increasing the opacity and smoothness of the surface.
 Conclusions New packaging materials created in the course of research - paper with a metallized coating can be used in packaging processes.

수경재배한 미니 파프리카 ‘뉴라온레드’ 저장온도 별 골판지박스 포장에서 수확후 특성 변화

The purpose of this study was to examine the effect of each storage temperature condition of 5, 10, 15 and 20oC to maintain the freshness of mini paprika (Capsicum annuum cv. New Raon Red) in corrugated box. Changes in general appearance, fresh weight loss, firmness, SSC (solid sugar content), and Hue angle were investigated. Furthermore, storage at temperatures ranging from 5oC to 15oC for 14 days resulted in maintaining freshness for 35 days. Paprika stored at 20oC showed significantly higher loss of fresh weight and firmness than that of other storage temperatures. Furthermore, paprika stored at 5oC and 10oC showed a lesser decrease in hue angle than that at 15oC and 20oC. However, the SSC of mini paprika was not significantly affected by storage temperature. These results suggest that corrugated box packaging in combination with low storage temperatures (5~10oC) could be effective in prolonging the shelf life of mini paprika. Therefore, the results represented that the low temperature storage in combination with cardboard box treatment could be effective in prolonging the shelf life of fresh paprika.
