Micro-leveler 1 , the next generation Auto-leveler

An auto-leveling system using feedback, correcting the density of fiber leading-ends (DFLE) in slivers, called Micro-leveler is presented. Computer simulations show that the Micro-leveler significantly outperforms Auto-levelers, especially in correcting stationary variations in the feed. In the Micro-leveler system, all the effects of variations in the properties of fibers that constitute the feed such as fiber length, fineness, orientation, folding, etc., are consolidated into a single impulse response that is characteristic of the feed. Thickness is modeled as a convolution of DFLE with this impulse response. Time-domain deconvolution with feedback allows the computation of DFLE, enabling leveling with much higher precision. The advantage of the proposed acceleration measurement at the scanning rollers, the need for capacitance measurements on the delivery-side, and the necessity for precise synchronization of the measurements and corrections are highlighted.

Translating science into the next generation meat quality program for Australian lamb

This paper introduces a series of papers in the form of a special edition that reports phenotypic analyses done in parallel with genotypic analyses for the Australian Sheep Industry Cooperative Research Centre (Sheep CRC) using data generated from the information nucleus flock (INF). This has allowed new knowledge to be gained of the genetic, environment and management factors that impact on the carcase and eating quality, visual appeal, odour and health attributes of Australian lamb meat. The research described involved close collaboration with commercial partners across the supply chain in the sire breeding as well as the meat processing industries. This approach has enabled timely delivery and adoption of research results to industry in an unprecedented way and provides a good model for future research.     

果蔬气调储藏的发展与特点

<正> 在社会主义市场经济条件下,我国现代食品工业经过几十年的发展,食品的生产和供应领域,已具备生产规模大、发展速度快、供给渠道广、运送距离远、管理层次多等特点,而这些却要求优化的储藏保鲜技术。 果蔬的储藏保鲜具有重要的意义。具体来说,果蔬一般集中收获,而人们要求常年供应,因此要求较长的储存期;另外,果蔬的产区相对集中,如南北方的水果品种差异很大,某些风味的水果只限于某一特定产区,而人们却希望全国供应,这就对储藏的技术提出了     

A next generation probiotic,Akkermansia muciniphila

Abstract

Akkermansia muciniphila, a symbiotic bacterium of the mucus layer, can utilize mucin as its sole carbon, nitrogen, and energy source. As an abundant resident in the intestinal tract of humans and animals, the probiotic effects of A. muciniphila including metabolic modulation, immune regulation and gut health protection, have been widely investigated. Various diseases such as metabolic syndromes and auto-immnue diseases have been reported to be associated with the disturbance of the abundance of A. muciniphila. In this review, we describe the biological characterization of A. muciniphia, the factors that influence its colonization of the intestinal tract; and discuss the current state of our knowledge on its role in host health and disease.     

Peer reviewed: managing the global environment

To enable future generations to drastically-and affordably-reduce carbon emissions if required, we must deal now with science and technology uncertainties.     

Health based pasta: redefining the concept of the next generation convenience food

Pasta, a delicious meal favorite and the signature dish of many of the world's most famous chefs and a bonding comfort meal for millions all over the world, it has been recognized as an identifying ingredient of traditional healthy Mediterranean and Latin American meals. Pasta has come a long way from the days when it was erroneously considered by consumers to be a "fattening food." Today it is perceived as one of the "healthy options." In fact, because pasta is so supremely versatile as a base to a meal, it is easily possible to serve it in ways to satisfy both our notions of "healthy eating" and our appetites for interesting and tasty food. Pasta, being so popular as a delicious family meal favorite and equally relished all over the world, it deserves a lot than any other food to serve as an ideal functional food. Here we analyze various health ingredients that have been incorporated in pasta as disease/disorder curing agents and/or potent nutritional supplements and their effects on cooking and quality parameters of pasta as well as their various health benefits and therapeutic attributes.

第二代高通量测序技术分析倒笃菜菌群

目的检测収酵食品倒笃菜中细菌和真菌菌群结构。方法利用第二代高通量测序对倒笃菜中的真菌和细菌菌群结构迚行测定分析。结果检测出倒笃菜产品中,细菌群落中占主要地位为假单胞菌属(Pseudomonas)、拟杆菌属(Bacteroides)和Faecalibacterium属,分别占比例为11.4%、9.3%和8.9%,而对収酵起至兲重要的芽孢乳杆菌属(Lactobacillus)仅占比例为1.1%。倒笃菜中真菌群落中占主要地位的真菌菌属为曲霉属(Aspergillus),占比为88.8%,而其余真菌占比仅为11.2%。其中,曲霉真菌属中存在可以产生真菌毒素的黄曲霉菌(A.flavus)、寄生曲霉菌(A.parasiticus)等。结论结果表明传统腌制倒笃菜产品中可能会存在一定的致病细菌与可产真菌毒素的真菌,从而有引起食品安全问题的风险,因此,应迚一步对倒笃菜微生物的安全性迚行深入检测分析。

等离子体表面改性与大气压辉光放电的产生

等离子体表面改性技术已经广泛地应用于织物的处理过程中。与传统的材料表面改性技术相比，等离子体改性有着高效、无污染、节能等优点。目前采用的低气压下的辉光放电进行表面改性，不能进行连续处理，且操作繁琐。利用大气压辉光放电可克服低压放电的缺点，因此，研究大气压辉光放电的产生有着重要的生产实践意义。文中论述了等离子体表面改性的作用机理、优点，介绍了产生大气压直流辉光放电和交流辉光放电的方法。     

Ultraprocessed plant-based foods: Designing the next generation of healthy and sustainable alternatives to animal-based foods

Numerous examples of next-generation plant-based foods, such as meat, seafood, egg, and dairy analogs, are commercially available. These products are usually designed to have physicochemical properties, sensory attributes, and functional behaviors that match those of the animal-sourced products they are designed to replace. However, there has been concern about the potential negative impacts of these foods on human nutrition and health. In particular, many of these products have been criticized for being ultraprocessed foods that contain numerous ingredients and are manufactured using harsh processing operations. In this article, the concept of ultraprocessed foods is introduced and its relevance to describe the properties of next-generation plant-based foods is discussed. Most commercial plant-based meat, seafood, egg, and dairy analogs currently available do fall into this category, and so can be classified as ultraprocessed plant-based (UPB) foods. The nutrient content, digestibility, bioavailability, and gut microbiome effects of UPB foods are compared to those of animal-based foods, and the potential consequences of any differences on human health are discussed. Some commercial UPB foods would not be considered healthy based on their nutrient profiles, especially those plant-based cheeses that contain low levels of protein and high levels of fat, starch, and salt. However, it is argued that UPB foods can be designed to have good nutritional profiles and beneficial health effects. Finally, areas where further research are still needed to create a more healthy and sustainable food supply are discussed.     

Evaluation of global onshore wind energy potential and generation costs

In this study, we develop an updated global estimate of onshore wind energy potential using reanalysis wind speed data, along with updated wind turbine technology performance, land suitability factors, cost assumptions, and explicit consideration of transmission distance in the calculation of transmission costs. We find that wind has the potential to supply a significant portion of the world energy needs, although this potential varies substantially by region and with assumptions such as on what types of land can be used to site wind farms. Total global economic wind potential under central assumptions, that is, intermediate between optimistic and pessimistic, is estimated to be approximately 119.5 petawatt hours per year (13.6 TW) at less than 9 cents/kWh. A sensitivity analysis of eight key parameters is presented. Wind potential is sensitive to a number of input parameters, particularly wind speed (varying by -70% to +450% at less than 9 cents/kWh), land suitability (by -55% to +25%), turbine density (by -60% to +80%), and cost and financing options (by -20% to +200%), many of which have important policy implications. As a result of sensitivities studied here we suggest that further research intended to inform wind supply curve development focus not purely on physical science, such as better resolved wind maps, but also on these less well-defined factors, such as land-suitability, that will also have an impact on the long-term role of wind power.
