Current Status, Recent Advances, and Main Challenges on Table Olive Fermentation: The Present Meets the Future

Table olives are among the most well-known fermented foods, being a vital part of the Mediterranean pyramid diet. They constitute a noteworthy economic factor for the producing countries since both their production and consumption are exponentially increasing year by year, worldwide. Despite its significance, olive’s processing is still craft based, not changed since antiquity, leading to the production of an unstable final product with potential risk concerns, especially related to deterioration. However, based on industrial needs and market demands for reproducible, safe, and healthy products, the modernization of olive fermentation processing is the most important challenge of the current decade. In this sense, the reduction of sodium content and more importantly the use of suitable starter cultures, exhibiting both technological and potential probiotic features, to drive the process may extremely contribute to this need. Prior, to achieve in this effort, the full understanding of table olive microbial ecology during fermentation, including an in-depth determination of microbiota presence and/or dominance and its functionality (genes responsible for metabolite production) that shape the sensorial characteristics of the final product, is a pre-requisite. The advent of meta-omics technology could provide a thorough study of this complex ecosystem, opening in parallel new insights in the field, such as the concept of microbial terroir. Herein, we provide an updated overview in the field of olive fermentation, pointing out some important challenges/perspectives that could be the key to the olive sector’s advancement and modernization.

Perspectives of Electricity Storage in Polymer Capacitors

The price and environmental aspects of electricity storage significantly affect the application of green technologies. The electrochemical batteries are currently the best choice for storing electricity for most industrial needs and products. Polymer capacitors show very low energy density compared to conventional batteries and therefore cannot be widely used for electricity disposal. At the same time, all other features of polymer capacitors that characterize battery systems are ideal. After a brief comparison of the basic properties of electrochemical and physical batteries, this paper presents the influence of electron trapping on the energy density of a polyethylene capacitor. The presented results indicate that the phenomenon of electron trapping in polymers can increase the energy deposit of polymer capacitors.

Pengaruh Fraksi Volume Serat Jerami Terhadap Kekuatan Material Komposit Aplikasi Kayu Lapis

Polymer Matrix Composite (PMC) is a composite material that uses a polymer matrix most widely used in industry, transportation, and everyday life. Plywood is one of the current industrial needs that is growing rapidly and is becoming a leading export. However, besides that, the availability of raw materials is decreasing along with deforestation. Resulting in the need for alternative raw materials. Straw is one of the largest wastes that is not utilized optimally. It can be used as straw as a reinforcing material for environmentally friendly composite materials. Composite material was made using the hand lay up method, with straw fiber purchased with 4% NaOH treatment using Yukalac 157 BQTN-EX unsaturated polyester resin and MEPOXE A hardener. Then, tensile testing was carried out with volume fractions of straw fiber 5%, 10% 20% and 30 % This shows that the volume fraction of straw fiber affects the strength of the composite material. The tensile strength value of the straw fiber composite meets the minimum standard for tensile strength in plywood. Judging from the surface structure of the composite material, there are voids or air bubbles. However, the most visible in the sample with fractions of 10% and 20%. Further research needs to be done with other tests such as hit test, sandpaper test to meet the requirements for SNI standard plywood.

University–industry collaboration in curriculum design and delivery: A model and its application in manufacturing engineering courses

The advantages and importance of university–industry collaboration, particularly in curriculum design and delivery, are well-known. However, although curriculum development models are available in the literature, very few are sufficiently concrete to be applicable in practice or are generalizable beyond their discipline of origin. In this paper, a co-operative model based on the Plan–Do–Study–Act cycle is presented and described. An example of its application in the curriculum design of two courses in welding within a Manufacturing Engineering Master’s program is detailed. The model was found successful based on the evaluation of the courses by students, teachers, and the industrial representatives involved. Therefore, it proved to be an effective tool for bridging the gap between industrial needs and academia in the field of Manufacturing Engineering education. At the same time, the methodology is generalizable and is applicable to any field of education.

Tensile Behaviour of Slag-based Engineered Cementitious Composit

Engineered Cementitious Composites (ECC) have become another alternative in the concrete industry due to their excellent strain capacity under uniaxial tension. Research and development for new ECC mix incorporating wastes remain open to fulfil the industrial needs to produce green and sustainable ECCs. This paper presents the experimental work on the tensile and cracking behaviour of ECCs utilising industrial waste, namely ground granulated blast-furnace slag (GGBS), to replace cement. A total of four slag-based ECC mixes containing 2%–2.5% of PVA fibres and 50%-60% GGBS were investigated under uniaxial compressive and tensile tests. Compressive strength, tensile strength and the crack behaviours of the slag-based ECCs were evaluated and compared with a control mix. The experimental results show that the slag-based ECCs can achieve tensile strain capacity 2.6 %–2.75 % and ultimate tensile strength 1.43 MPa–2.82 MPa at 28 days. It was also found that the ECCs with GGBS and fibres formed few hairline cracks at the gage of the dog bone compared to brittle fracture in the control specimens.

A Case Study on Remote Instrumentation of Vibration and Temperature in Bearing Housings

Data collection is one of the most relevant topics of modern automation and industry. It is usually a costly and time-consuming task, especially in continuous processes. Our case study takes place in a sugar cane mill. The required continuous operation of a belt conveyor for bagasse transportation makes it a critical system in the overall production process. Therefore, a predictive maintenance tool is highly applicable here. We identified bearing housings as critical points for data collection intended for prognostics of the conveyor. However, given the number of points, the cost of a commercial solution becomes unfeasible by our company. This paper reports the development of low-cost devices for measurements and wireless transmission of vibration and temperature data from bearing housings. We assessed several sensor options and made decisions based on a cost-suitability commitment, which led to the design of the electronic devices. The devices were tested for correct operation, reliability (99%), and relative measurement errors under 1.2%. From the tests, we conclude that our proposal is appropriate for our case study’s industrial needs and budget restrictions.

Construction Safety Law

<p>The development of industrial safety law in Britain and New Zealand and the origins of construction, safety law are outlined in Part I. The administration and interpretation of the Construction Act 1959 are described in Part II, and Part III highlights the comparable statute law in three Commonwealth countries. The thesis will assist persons engaged in industry, lawyers and departmental officers in the understanding of the law and its application to construction work. The information presented on overseas law will assist those involved in the task of reviewing and consolidating the New Zealand industrial safety, health and welfare legislation. The history of the British Factories Acts leading on to the Health and Safety at Work Act 1974, described in Chapter 1, highlights the importance of a self-regulating, integrated statutory system and a professional inspectorate with an advisory role and residual enforcement powers. New Zealand safety law has developed as the country's industrial needs have determined, as will be seen from Chapter 2. Generally, British statutes have been adopted, but construction safety law is the exception and Chapter 3 shows that, from the earliest Bill introduced by Richard John Seddon in 1892 up to the present, the legislation covering the construction industry has been initiated and drafted with industry representation. The more empirical subjects such as current policy and practice, sanctions, codes, education, other legislation and reform, as well as the purpose, effect, extent and application of the Construction Act 1959 are discussed in Chapter 4. The results of the author's legal research and analysis are contained in Chapters 5 and 6 under the headings of 'Liabilities' and 'Technical Law'. The responsibilities of employers, workmen, safety supervisors, inspectors and the Crown are set out and explained in terms of the statute and the interpretation from the case law. The technical subjects include scaffolding, guardrails, brittle roofing, fall of objects, access, excavations, mechanical plant, demolition, eye protection, asbestos, work in compressed air, health and welfare. Chapters 7, 8 and 9 examine the present legislation, in Britain, Australia and Canada and indicate a trend towards a unified approach to occupational safety, health and welfare and one enactment for all places of work, and with separate regulations and codes of practice for each industry. This study has been carried out by the present Chief Safety Engineer of the Department of Labour who has been responsible for the administration of the Construction Act 1959 since 1968. A separately bound appendix includes a copy of the Construction Act 1959 and the Amendments (Appendix A), the Inspection of Building Appliances Bill 1892 (Appendix B), the Scaffolding Inspection Act 1906 (Appendix C), the Tasmanian Industrial Safety, Health and Welfare Act 1977 (Appendix D), the Ontario Occupational Health and Safety Act 1978 (Appendix E), and copies of the unreported judgments and decisions referred to in the thesis (Appendix F).</p>
