Portraits of the Historical Jesus
Portraits of the historical Jesus refers to the various biographies of Jesus that have been constructed in the three separate scholarly quests for the historical Jesus that have taken place in the past two centuries, each with distinct characteristics and developing new and different research criteria. The portraits of Jesus that have been constructed in these processes have often differed from each other, and from the dogmatic image portrayed in the gospel accounts. These portraits include that of Jesus as an apocalyptic prophet, charismatic healer, Cynic philosopher, Jewish Messiah and prophet of social change, but there is little scholarly agreement on a single portrait, or the methods needed to construct it. There are, however, overlapping attributes among the various portraits, and scholars who differ on some attributes may agree on others. By the 21st century scholars began to focus on what is historically probable and plausible about Jesus.

Reductive Aminations with Metal Catalysts
Recently, N-substituted anilines have been the object of increasing research interest in the field of organic chemistry due to their role as key intermediates for the synthesis of important compounds such as polymers, dyes, drugs, agrochemicals and pharmaceutical products. Among the various methods reported in literature for the formation of C–N bonds to access secondary anilines, the one-pot reductive amination of aldehydes with nitroarenes is the most interesting procedure, because it allows to obtain diverse N-substituted aryl amines by simple reduction of nitro compounds followed by condensation with aldehydes and subsequent reduction of the imine intermediates. These kinds of tandem reactions are generally catalyzed by transition metal-based catalysts, mainly potentially reusable metal nanoparticles.

3′UTR Length Dynamics: Releasing mRNAs from Stability Control
The 3′Untranslated regions (3′UTRs) of mRNAs, are non-coding regulatory platforms that control stability, fate and the correct spatiotemporal translation of mRNAs. Although initially considered as stabilizing features of the ORF, further work identified a number of new 3’UTR functions that controlled where, when and how mRNAs were translated. Furthermore, recent research has enriched the view of 3’UTRs from static regulators of mRNA translation to highly dynamic and modular regulatory platforms that respond to different stimuli by changing their structure. By using alternative polyadenylation and cleavage sites, alternative exons or by including exonized Alu cassettes, 3’UTRs modify their length, change their sequence and consequently their inventory of associated regulatory sites to establish different co-regulatory events.

L-Twin
A V-twin engine, also called a V2 engine, is a two-cylinder piston engine where the cylinders share a common crankshaft and are arranged in a V configuration. Although widely associated with motorcycles (installed either transversely or longitudinally), V-twin engines have also been used for industrial engines and in several small cars. The V-twin design dates back to the late 1880s.

1994 Scotland RAF Chinook Crash
On 2 June 1994, a Chinook helicopter of the Royal Air Force (RAF), serial number ZD576, crashed on the Mull of Kintyre, Scotland, in foggy conditions. The crash resulted in the deaths of all twenty-five passengers and four crew on board. Among the passengers were almost all the United Kingdom's senior Northern Ireland intelligence experts. The accident is the RAF's worst peacetime disaster. In 1995, an RAF board of inquiry ruled that it was impossible to establish the exact cause of the accident. This ruling was subsequently overturned by two senior reviewing officers, who stated the pilots were guilty of gross negligence for flying too fast and too low in thick fog. This finding proved to be controversial, especially in light of irregularities and technical issues surrounding the then-new Chinook HC.2 variant which were uncovered. A Parliamentary inquiry conducted in 2001 found the previous verdict of gross negligence on the part of the crew to be 'unjustified'. In 2011, an independent review of the crash cleared the crew of negligence.

Biofuel Supply Chain
Bioenergy is one of the alternatives to secure energy demand, despite increasing debate on the sustainability of using bioenergy as a renewable source. As the source is disseminated over a large area and affected by seasonality, the potential benefit is highly dependent on other cost and benefit trade-offs along the supply chain.

Five-Minute Speech Sample for High Expressed Emotion
Expressed Emotion (EE) describes the tone of a caregiver’s response to a patient with a mental disorder, and it is used to predict relapse. The Five-Minute Speech Sample (FMSS) is a 5-min interview with a caregiver that evaluates only two EE dimensions. The FMSS emerged as a valid and reliable tool for measuring EE as a predictor of relapse in patients with schizophrenia and major depressive disorder. Patient age and duration of illness had no significant effect on the results. Future meta-analyses should include more studies to reduce publication bias. EE may be a good predictor of relapse when examined through a fast measurement technique such as the FMSS, which may also be useful to analyze the psychopathological structure of caregivers.

Polyphenolic-Food and Longevity
Aging and, particularly, the onset of age-related diseases are associated with tissue dysfunction and macromolecular damage, some of which can be attributed to accumulation of oxidative damage. Recently, growing interest has emerged on the beneficial effects of plant-based diets for the prevention of chronic diseases including obesity, diabetes, and cardiovascular disease. Several studies collectively suggests that the intake of polyphenols and their major food sources may exert beneficial effects on improving insulin resistance and related diabetes risk factors, such as inflammation and oxidative stress. They are the most abundant antioxidants in the diet, and their intake has been associated with a reduced aging in humans. Polyphenolic intake has been shown to be effective at ameliorating several age-related phenotypes, including oxidative stress, inflammation, impaired proteostasis, and cellular senescence, both in vitro and in vivo.

Mycotoxin Control in Foods
Mycotoxins are the most well-known food contaminants causing significant damage to both human and animal health. The main producers of mycotoxins are the fungi of the genera of Aspergillus, Fusarium, Penicillium, Claviceps and Alternaria. Due to the serious toxicological effects of consuming mycotoxin contaminated foods, it is necessary to control them. In order to control mycotoxin contamination, two key strategies are followed.These strategies mainly focus on the prevention of mycotoxins and detoxification. The implementation of pre- and post-harvest control systems includes good agricultural practices (GAPs), good manufacturing practices (GMPs), appropriate environmental factors, favorable storage practices and biological, chemical and physical methods as decontamination and detoxification strategies.

Shape-Memory Polymers in Dentistry
Objective: To perform a systematic review (SR) of existing literature and a patent landscape report (PLR) regarding the potential applications of shape-memory polymers (SMPs) in dentistry. Search strategy: Clinical and Biomedical online databases (Pubmed, Medline via Embase, Scopus, LILACS, Web of Science, Cochrane Library), Materials Science and Engineering databases (IEEE Explore, Compendex, Proquest), Material Science and Chemical database (Reaxys) so as Patents databases (Questel-Orbit, Espacenet, Patentscope) were consulted as recently as January 2019 to identify all papers and patents potentially relevant to the review. The reference lists of all eligible studies were hand searched for additional published work. Results: After duplicate selection and extraction procedures, 6 relevant full-text articles from the initial 302 and 45 relevant patents from 497 were selected. A modified Consolidated Standards of Reporting Trials (CONSORT) checklist of 14 items for reporting pre-clinical in-vitro studies was used to rate the methodological quality of the selected papers. The overall quality was judged low. Conclusions: Despite the great potential and versatility of SMPs, it was not possible to draw evidence-based conclusions supporting their immediate employment in clinical dentistry. This was due to the weak design and a limited number of studies included within this review and reflects the fact that additional research is mandatory to determine whether or not the use of SMPs in dentistry could be effective. Nevertheless, the qualitative analysis of selected papers and patents indicate that SMPs are promising materials in dentistry because of their programmable physical properties. These findings suggest the importance of furtherly pursuing this line of research.
