The purpose of this paper is to compare the bursting strength, bursting distension, air permeability and wale wise wicking rate properties of recycled polyester (r-PET) and virgin polyester (v-PET) raw materials from which single jersey knitted fabric samples are manufactured. Meanwhile, numerical optimization method was used in predetermined parameters to determine the optimum r-PET and v-PET blend ratio and yarn manufacturing technology. In the optimization analysis, the average values of the important yarn and fabric properties inspected were taken as a target according to the 50 percent proportion of r-PET and v-PET fiber for both compact and ring yarn manufacturing technology.

To encourage the use of value-added textile products produced from recycling PET bottle with the focus of social responsibility is a condition that should be evaluated within the scope of waste management. The recycling of PET bottles and finding new opportunities for the uses in different field are crucial for both contributing environmental economy and conserving natural energy resources. The most important alternative ways is to use the r-PET fiber from recycling PET bottle in textile industry. In this study, 19.7 tex r-PET/cotton and v-PET/cotton-blended compact and ring spun yarns were produced at different blending ratios at the same production parameters.

Results showed that blend type, blend ratio and yarn manufacturing technology have statistical significance effect on bursting strength and air permeability. Besides, it was found that blend type has no significance on wale wise wicking rate unlike other parameters. Optimization analysis indicated that single jersey knitted fabric with v-PET/CO 58.62/41.38 percent compact yarn had higher desirability with the value of 0.72.

At the present time, r-PET fiber is blended in small amount (approximately 5–15 percent blend ratio) with both cotton and polyester together. In addition, it is possible using different fiber blend types instead of cotton and polyester according to the usage area. The most important question is to determine the amount of r-PET proportion. In other words, both optimum yarn/fabric quality parameters should be ensured and at the same time life cycle of the apparels should not be short when the optimum r-PET proportion is taken into consideration.

The purpose of this paper is to investigate the acoustic properties of needle-punched nonwovens produced of bamboo, banana and hemp fibers blended with polyester (PET) and polypropylene (PP) as they are supportive enough to minimize sound transmission inside the automobiles.

Textile materials like bamboo, banana and hemp blended with PET and PP in the ratio of 35:35:30 were applied to make the web. The needle-punching technique was applied to each web for three times to form a full nonwoven textile composite. The concept of PET/PP blend with natural fibers was to enhance the consistency and thermoform propensity of the composites. When nonwoven textile composites were placed in between a sound source and a receiver, they absorbed annoying sound by dissolving sound wave energy. Sound absorption coefficient was measured by the impedance tube method as per ASTM C384 Standard. Bamboo/PET/PP composite showed the highest absorption coefficient in most of the frequencies.

Physical and comfort properties were tested for the composites and it was noticed that bamboo/PET/PP composites with its compressed structure showed a better stiffness value, lesser thermal conductivity, lesser air permeability, better absorption coefficient and highest sound transmission loss compared to other two composites. At 840 Hz, the absorption coefficient of bamboo/PET/PP remained in satisfactory level but it was inferior by 20 percent in banana/PET/PP. Conversely at more frequencies like 1,680 Hz, there was a decrease from the target level in all the nonwovens composites, which could be enhanced by raising the thickness of the nonwovens, and all these properties of bamboo/PET/PP were considered appropriate for controlling noise inside the vehicles.

This research will provide facilities to decrease noise inside the vehicles. It will improve the apparent value of the automobiles to the traveler and also provide a sensible goodwill to the manufacturer.

This research will open several ways for the development of different nonwoven composites, particularly for the sound absorption and will open possible ways for the scholars to further study in this field.

This article adopts Foucault's notion of a bipolar technology of disciplinary power and regulatory biopower to address the tension between discipline and freedom in domestic relationships between human and nonhuman animals commonly referred to as “pets.” In doing so, the article examines the promises and pitfalls of thinking through pet keeping as a form of lived, posthumanist critique.

The argument relies on an interview study with 20 pet owners—most of the interviews conducted in their homes together with their pets—to conceptualize how they organize their lives in relation to their pets.

The analysis shows that the boundaries of the home, the play of power between bodies, and the “conditions of an unconditional love” are central to producing the pet relationship as inherently meaningful and as an indispensable part of the lives of both pet keepers and pets. A balance between discipline and freedom enables the construction of both human and other identities: pet owners produce their pets' subjectivity by speaking of them as autonomous persons, while pets' presence in the home also enables their owners' subjectivity.

The article critically examines interspecies relationships, which by extension can benefit nonhuman animals. It argues that pet keeping can challenge anthropocentrism and unsustainable consumption lifestyles, but it may also reinforce prevailing biopolitical logics, if it remains maintained within a secluded domestic or cultural sphere.

The article draws on original data. While Foucauldian theory has been used to discuss pet keeping, empirical studies of pet keeping that rely on this theoretical framework are scarce.

To develop a theory of concepts that solves the combination problem, i.e. to deliver a description of the combination of concepts. We also investigate the so‐called “pet fish problem” in concept research.

The set of contexts and properties of a concept are embedded in the complex Hilbert space of quantum mechanics. States are unit vectors or density operators and context and properties are orthogonal projections.

The way calculations are done in Hilbert space makes it possible to model how context influences the state of a concept. Moreover, a solution to the combination problem is proposed. Using the tensor product, a natural product in Hilbert space mathematics, a procedure for describing combined concepts is elaborated. This procedure also provides a solution to the pet‐fish problem, and it allows the modeling of an arbitrary number of combined concepts. By way of example, a model for a simple sentence containing a subject, a predicate and an object, is presented.

The combination problem is considered to be one of the crucial unsolved problems in concept research. Also the pet‐fish problem has not been solved by earlier attempts of modeling.

This paper introduces more-than-human perspective in information behaviour and information experience studies. The purpose of this paper is to contribute to understandings of the concept of multispecies families by exploring their significant dimensions related to information phenomena involving multiple contexts, situations, spaces, actors, species, and activities.

Based on previous research in human information behaviour and human-animal studies, our ideas around information experience of multispecies families are developed conceptually. The paper builds both on previous empirical findings about human information behaviour and the new domain of information experience.

The paper proposes a holistic approach both to information phenomena in everyday living with companion animals including embodied, affective, cognitive, social, digital, and objectual information that shapes pet care and management practices, and to the context of study, including work, domestic, and leisure aspects of multispecies family.

This study broadens our understanding of information phenomena in multispecies families, and so contributes to the field of information experience. It also provides insights for animal welfare scientists to help them understand the information behaviour of humans who are responsible for keeping and caring for animals.

Poly(ethylene terephthalate) (PET) waste from soft drink bottles was incorporated into palm olein alkyd to produce new polyol for use in polyurethane resins as surface protection on metal surfaces.

Alkyd was prepared from palm olein, glycerol and phthalic anhydride. PET underwent simultaneous glycolysis and transesterification reactions with the alkyd. Varying the amount of PET has led to polyols with different viscosities. Polyurethane resins were produced by reacting the polyols with toluene diisocyanate. The resins were coated on mild steel panels and cured. Performances of the cured films were tested.

The polyurethanes (PU) resin cured to a harder film with better thermal stability. Films showed excellent adhesion properties, while higher content of PET exhibited higher pencil hardness, better water, salt, acid and alkali resistance.

Other vegetable oils could also be used. The alkyd structure could be changed by formulation to have different functionality and the ability to incorporate higher amount of PET waste. Rate of glycolysis of PET could be increased by higher amount of ethylene glycol.

This method has managed to use waste PET in producing new polyol and PU resins. The cured films exhibit good mechanical and chemical properties, as well as excellent adhesion and thermal stability.

The non-biodegradable PET has created environmental pollution problems connected to littering and illegal landfilling. It has become necessary to pay greater attention to recycling PET bottles for obtaining valuable products.

This approach is different from the earlier reports, where PET was recycled to recover the raw materials.

The purpose of this paper is to present an overview of the pet-friendliness trend, because despite its growth, there has been little research on the benefits and potential risks of pet-friendly workplaces.

A general review is provided on pet ownership figures in North America and the benefits and drawbacks of pet ownership. Pet-friendly policies and practices are described, highlighting their potentially positive impact on well-being and performance. Possible concerns with pet-friendly workplaces are examined. The paper offers recommendations for organizations that are potentially interested in becoming pet-friendly.

Many households in North America have pets that are considered genuine members of the family. As a result, workplaces are increasingly becoming “pet-friendly” by instituting policies that are sensitive to pet ownership. The scope of pet-friendly policies and practices ranges from simple to more complex measures. Adopting these measures can result in benefits that include enhanced attraction and recruitment, improved employee retention, enhanced employee health, increased employee productivity, and positive bottom-line results. But there are also concerns regarding health and safety, property damage, distractions, and religious preferences.

The range of pet-friendly measures could apply to any workplace that is interested in improving their efforts toward recruitment, retention, and productivity, among others.

This paper describes a range of efforts that workplaces can offer to enhance their employees’ work lives and is the first to provide a detailed account of the pet-friendliness trend.

The purpose of this paper is to explore to what extent the legal environment influences a user’s choice to employ privacy-enhancing technologies (PETs). Drawing upon existing theoretical frames specific to arbitrariness and uncertainty, this research examines whether interest in PETs is influenced by the legal environment of a country.

Using data from Google Trends, the International Property Rights Index, Freedom House and the Organization for Economic Cooperation and Development, the research analyzes interest in Tor, VPN technology and pretty good privacy (PGP) in 153 countries between 2012 and 2016.

Findings suggest both countries with both higher and lower arbitrariness and uncertainty of law are associated with an increased interest in Tor and PGP. However, interest in VPN technology does not appear influenced by the legal environment and, instead, is influenced by freedom within the press.

The dual use nature of Tor and PGP is influenced by law enforcement and judiciary effectiveness and transparency and arbitrariness contributing to the public’s interest in decentralized technological protections.

Law enforcement should continue to police via the technologies rather than shutting them down to protect the identities of those needing to use these technologies for legitimate purposes. Only by embracing the technologies, as opposed to seeing them as hurdles to be banned, may law enforcement agencies remain vigilant to the threats posted by nefarious actors.

In this study, the authors introduce a more robust measure of interest in PETs, and do so with a larger, more substantive sample. By situating this interest within the context of policing, the authors can document the dual use nature of the technology, which can be useful in guiding future research, specifically in the area of policy development and officer training.

This paper aims to review the latest management developments across the globe and pinpoints practical implications from cutting-edge research and case studies.

This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context.

On the face of it, taking pets to work seems at best to be an idea guaranteed to polarize opinion. On the one hand, some people love dogs and cats, and will gain great satisfaction and peace of mind from having their pets close at hand, or be able to interact with both others’ pets about the workplace. However, on the other hand, there are many people who simply loathe animals, or fear them, or are unable to go near them due to allergies. Having pets at work might work for some, but might not work for others at all.

Provides strategic insights and practical thinking that have influenced some of the world’s leading organizations.

This paper aims to focus on achieving triple-shape memory effect (triple-SME) of a commercial poly (ethylene terephthalate) (PET) film with the thickness of 100 µm.

The thermal characteristics and microstructure of PET film were characterized by differential scanning calorimetry, thermogravimetric analysis and wide-angle X-ray diffraction analysis. The dual-shape memory effect (dual-SME) of the PET film was then systematically investigated, and based on that, triple-SME in thin PET film was achieved.

Investigation of the dual-SME in PET film revealed the difference between recovery temperature and programming temperature reduced with increasing programming temperature. An obvious intermediate shape shifting between the original and final programmed shape was observed during shape recovery in triple-shape memory behaviors.

Compared with dual-SME in polymer, relatively less work has been done on multi-SME in polymer, especially in thin polymer film. In this study, triple-SME in a PET film was investigated based on the results of dual-SME of the film. The main implication of the study is on how to achieve a watermark between the final programmed pattern and the original pattern, for the application of shape memory polymer in anti-counterfeiting label.

Dual- and triple-SMEs were achieved in a PET film that is only 100 µm in thickness, and the underlying mechanism for the difference between programming temperature and recovery temperature was discussed. For the novel application of triple-SME in anti-counterfeit label, the watermark during shape recovery in triple-SME can effectively prevent duplication.
