Submarine Cables Radial Water Barrier
The submarine cables manufacturing industry is growing very rapidly. Solutions used so far, usually adapted from designs of land cables, do not fulfil the new, more demanding requirements. The phenomenon of water ingress into insulation and its absorption are basic factors determining the service life of submarine cables. The radial water barrier is the only effective component of cable design that may guarantee the required minimum 30-year longevity of submarine cables.

Swisscom
Swisscom AG is a major telecommunications provider in Switzerland. Its headquarters are located at Worblaufen near Bern. The Switzerland owns 51.0 percent of Swisscom AG. According to its own published data, Swisscom holds a market share of 60% for mobile, 67% for broadband and 33% for TV telecommunication in Switzerland. Its Italian subsidiary Fastweb is attributed 16% of private clients and 29% of corporate clients share of Italian broadband and is also active in the mobile market. The Swiss telegraph network was first set up in 1852, followed by telephones in 1877. The two networks were combined with the postal service in 1920 to form the PTT (Postal Telegraph and Telephone). It struggled to develop a homegrown digital network, with the first digital exchange launched in 1986, but pioneered the NATEL A mobile service in 1978 and the GSM-based NATEL D offering a digital service in 1993. The Swiss telecommunications market was deregulated in 1997. Telecom PTT was spun off and rebranded Swisscom ahead of a partial privatisation in 1997 which has left the Swiss government with a 51% stake. Besides pioneering the first mobile telephone network NATEL A, the present-day Swisscom owns the protected brand NATEL, which is used and known only in Switzerland . 25% of Swisscom Mobile was sold to Vodafone in 2001. Since then, Swisscom has bought a majority stake in Italy's second-biggest telecom company Fastweb and invested in areas such as hospitality support, cloud services, mobile solutions and billing.

Seaweeds in Producing Safe and Sustainable Bio-Packaging
Diverse studies demonstrate that seaweed polysaccharides (e.g., alginates and carrageenans) not only provide health benefits, but also contribute to the production of biopolymeric film and biodegradable packaging. The dispersion of plastics and microplastics in the oceans provoke serious environmental issues that influence ecosystems and aquatic organisms. Thus, the sustainable use of seaweed-derived biopolymers is now crucial to replace plasticizers with biodegradable materials, and thus preserve the environment.

Proto-Philippine
The Proto-Philippine language is a reconstructed ancestral proto-language of the Philippine languages, a proposed subgroup of the Austronesian languages which includes all languages within the Philippines (except for the Sama–Bajaw languages) as well as those within the northern portions of Sulawesi in Indonesia. Proto-Philippine is not directly attested to in any written work, but linguistic reconstruction by the comparative method has found regular similarities among languages that cannot be explained by coincidence or word-borrowing.

Anti-Fungal Efficacy of Flavonoids
The prevalence of fungal infections is growing at an alarming pace and the pathogenesis is still not clearly understood. Recurrence of these fungal diseases is often due to their evolutionary avoidance of antifungal resistance. The development of suitable novel antimicrobial agents for fungal diseases continues to be a major problem in the current clinical field. Hence, it is urgently necessary to develop surrogate agents that are more effective than conventional available drugs. Among the remarkable innovations from earlier investigations on natural-drugs, flavonoids are a group of plant-derived substances capable of promoting many valuable effects on humans. The identification of flavonoids with possible antifungal effects at small concentrations or in synergistic combinations could help to overcome this problem. A combination of flavonoids with available drugs is an excellent approach to reduce the side effects and toxicity.

Nanotyrannus
Nanotyrannus ("dwarf tyrant") is a likely invalid genus of tyrannosaurid dinosaur. It is known from only a single certain specimen, CMNH 7541, that was originally proposed to be a distinct genus based on a handful of cranial and postcranial features. It has since been suggested to be juvenile of the contemporary species Tyrannosaurus rex, based on a lack of mature specimens and the proposed diagnostic traits being variable within the species, a conclusion that is not universally accepted.

Carbon-Based Quantum Dots for Supercapacitors
Carbon-based Quantum dots (C-QDs) are carbon-based materials that experience the quantum confinement effect, which results in superior optoelectronic properties. In recent years, C-QDs have attracted attention significantly and have shown great application potential as a high-performance supercapacitor device. C-QDs (either as a bare electrode or composite) give a new way to boost supercapacitor performances in higher specific capacitance, high energy density, and good durability. This review comprehensively summarizes the up-to-date progress in C-QD applications either in a bare condition or as a composite with other materials for supercapacitors. The current state of the three distinct C-QD families used for supercapacitors including carbon quantum dots, carbon dots, and graphene quantum dots is highlighted.

Boeing 787 Dreamliner Battery Problems
In 2013, the second year of service for the Boeing 787 Dreamliner, a widebody jet airliner and several aircraft suffered from electrical system problems stemming from its lithium-ion batteries. Incidents included an electrical fire aboard an All Nippon Airways 787 and a similar fire found by maintenance workers on a parked Japan Airlines 787 at Boston's Logan International Airport. The United States Federal Aviation Administration (FAA) ordered a review into the design and manufacture of the Boeing 787 Dreamliner, followed by a full grounding of the entire Boeing 787 fleet, the first such grounding since that of the McDonnell Douglas DC-10 in 1979. The plane has had two major battery thermal runaway events in 52,000 flight hours, which was substantially less than the 10 million flight hours predicted by Boeing, neither of which were contained safely. The National Transportation Safety Board (NTSB) released a report on December 1, 2014, and assigned blame to several groups:

Shelf Life
Shelf life is the length of time that a commodity may be stored without becoming unfit for use, consumption, or sale. In other words, it might refer to whether a commodity should no longer be on a pantry shelf (unfit for use), or just no longer on a supermarket shelf (unfit for sale, but not yet unfit for use). It applies to cosmetics, foods and beverages, medical devices, medicines, explosives, pharmaceutical drugs, chemicals, tires, batteries and many other perishable items. In some regions, an advisory best before, mandatory use by or freshness date is required on packaged perishable foods. The concept of expiration date is related but legally distinct in some jurisdictions.

EBV Lytic Induction therapy
Epstein-Barr virus (EBV) lytic induction therapy is an emerging virus-targeted therapeutic approach that exploits the presence of EBV in tumor cells to confer specific killing effects against EBV-associated malignancies. Efforts have been made in the past years to uncover the mechanisms of EBV latent-lytic switch and discover different classes of chemical compounds that can reactivate the EBV lytic cycle. Despite the growing list of compounds showing potential to be used in the lytic induction therapy, only a few are being tested in clinical trials with varying degrees of success. This review will summarize the current knowledge on EBV lytic reactivation, the major hurdles of translating the lytic induction therapy into clinical settings and highlight some potential strategies in the future development of this therapy for EBV-related lymphoid and epithelial malignancies.

Scopophobia
Scopophobia, scoptophobia, or ophthalmophobia is an anxiety disorder characterized by a morbid fear of being seen in public or stared at by others. Similar phobias include erythrophobia, the fear of blushing, and an epileptic's fear of being looked at, which may itself precipitate such an attack. Scopophobia is also commonly associated with schizophrenia and other psychiatric disorders. Often scopophobia will result in symptoms common with other anxiety disorders. Scopophobia is unique among phobias in that the fear of being looked at is considered both a social phobia and a specific phobia.

China’s Elder Care Policies
Until the 1980s, institutional elder care was virtually unknown in China. In a few decades, China had to construct a universal social safety net and assure basic elderly care. China’s government has been facing several challenges: the eroding traditional family care, the funding to assure care services for the older population, as well as the shortage of care delivery services and nursing staff. In Western countries, elder care policies have been shifting to the home care approach. China introduced home care as the elder care cornerstone and encouraged the revival of the filial piety tradition. Although China has a unique approach, the care policies for the aged population in China and Western countries are converging by emphasizing home-based care, informal care and healthy aging.
