Criminology must maintain relevance in a changing world and engage with new challenges. Perhaps pre-eminent among those facing the planet today are threats to the natural environment and, by extension, to human health and rights and to other species. A green criminology has emerged as a (now well established) criminological perspective that addresses a wide range of harms, offences, and crimes related to the environment and environmental victims. This chapter provides a review of green criminological work on climate change, consumption and waste, state-corporate and organized crimes, animal abuse, and wildlife trafficking. It also considers the strengths and weaknesses of current approaches to regulation and control.

Linear triquinane sesquiterpenoids represent an important class of natural products. Most of these compounds were isolated from fungi, sponges, and soft corals, and many of them displayed a wide range of biological activities. On account of their structural diversity and complexity, linear triquinane sesquiterpenoids present new challenges for chemical structure identification and total synthesis. 118 linear triquinane sesquiterpenoids were classified into 8 types, named types I–VIII, based on the carbon skeleton and the position of carbon substituents. Their isolation, structure elucidations, biological activities, and chemical synthesis were reviewed. This paper cited 102 articles from 1947 to 2018.

New challenges in the efficient management of cities depend on a deep knowledge of their inner structures. It is therefore very important to have access to reliable models of cities characteristics and organization. This paper aims at providing and validating a stochastic modelization based on statistical data of buildings parameters which can be useful as an entry for many other models considered in a wide range of fields where buildings structure is a main factor of a thorough modelization of cities. The interest of such an approach is highlighted through the detection of errors in the data or as a tool for visual clustering.

Blockchain technology, which would be the underlying technology, has recently become very popular with the increase in cryptocurrencies and is being used in IoT and other fields. There have been shortfalls, however, which impede its implementation, including the volume of space. Transactions will be produced at a significant level due to the huge amount of Connected systems that often work in many networks as data processors. In IoT, the storage issue will become more intense. Current storing data platforms have a wide range of features to respond to an extensive variety spectrum of uses. Nevertheless, new groups of systems have arisen, e.g., blockchain with data version control, fork semantics, tamper-evidence or some variation thereof, and distributed analysis. They're showing new challenges for storage solutions to effectively serve such energy storage Systems by integrating the criteria mentioned in the processing. This paper discusses the potential security and privacy concerns of IoT applications and also it is shown that in first step the storage is enhanced by 50% and further in the next step, it is improved and it takes only 256 bytes irrespective of the input data size.

First Time

Registered Reports are a form of empirical journal article in which study proposals are peer reviewed and pre-accepted before research is undertaken. By deciding which articles are published based on the question, theory, and proposed methods, Registered Reports offer a powerful remedy for a range of reporting and publication biases. Here we reflect on the history, progress and future prospects of the Registered Reports initiative, and also offer practical guidance for authors, reviewers, and editors encountering the format for the first time. While the key ingredients of pre-study review and results-blind acceptance are far from novel – and are already adopted independently in a variety of contexts – Registered Reports are the first mechanism to combine them into a mainstream policy that has won appeal with multiple stakeholders in the research process. We review early evidence that Registered Reports are working as intended, while at the same acknowledging that they are not a universal solution for irreproducibility. We also consider how the policies and practices surrounding Registered Reports are changing, or must change in future, to address limitations and adapt to new challenges. In spite of these caveats, we conclude that Registered Reports are promoting reproducibility, transparency and self-correction across a wide range of disciplines, and may help reshape how society evaluates research and researchers.

Today, asthenia is one of the most common syndromes in the practice of a doctor of any specialty. Her treatment uses a comprehensive approach that includes physical training, psychotherapy, diet and pharmacotherapy. Pharmacotherapeutic treatment of asthenia includes the appointment of antidepressants, nootropics, tranquilizers, psychostimulants, neuroleptics. Given the multimodality and multilevel nature of the lesion of the nervous system in CОVID-19, in the recovery period, it is advisable to prescribe complex drugs with a wide range of therapeutic possibilities. The use of herbal drugs, in particular Vazavital Neuro and Cardiolin, is considered promising.

AbstractIn some industrial situations, components are subject to repetitive impact in the presence of a slurry. A novel repetitive impact-with-slurry test rig was developed to evaluate the behaviour of a wide range of engineering materials in such conditions. The test materials could be categorised into five main groups – heat treated steels, stainless steels, chromium cast irons, hardfacing coatings and superalloys. Three-dimensional surface topography was used to quantify the depths and volumes of the produced wear scars. Post-test metallurgical examination was also conducted to further evaluate the wear processes. The wear mechanisms could be split into two main groups of materials; ductile materials were observed to plastically deform and hard/brittle materials demonstrated cracking/spalling mechanisms. Hardened martensitic-type materials exhibited the greatest resistance to repetitive impact wear.

The COVID-19 pandemic for healthcare workers is a situation of pronounced emotional stress in connection with professional activities. Healthcare professionals face new challenges in treating COVID-19 and, at the same time, they must also continue to successfully treat non-COVID-19 patients and fulfill personal responsibilities, including caring for their families and themselves. It is imperative to tackle the burnout problem affecting the wide range of healthcare professionals currently battling the COVID-19 pandemic.
