First Time

On January 10-15 with. For the first time the reports of the institutes for advanced training of doctors (Leningrad and Kazan) were heard in the Plenum of Ts. B. for the first time. In both in-tah the cyclic system is practiced, however in its content it differs from each other. The cyclic system of the Kazan Institute is a complex system of a number of disciplines (internal diseases, nervous, physical, children's make up a therapeutic cycle, surgery, obstetrics and gynecology and orthopedics a surgical cycle, and an eye cycle). Listening to the subjects of these cycles is mandatory for students during the semester, only a bias in one discipline or another is allowed. The cycles at the Leningrad Institute cover a number of courses in one discipline: a separate cycle of internal diseases, a cycle of nervous diseases, etc .; a visiting physician has the opportunity to freely define himself for two cycles at his own discretion. The debate on this issue revealed that each of these systems has its own advantages and the regulations adopted on the reports will preserve these systems for the near future. The proposal to unify systems for both institutes did not meet with support.

Epimedium elatum (Morren & Decne) of family Berberidaceace is a rare perennial medicinal plant, endemic to high altitude forests of Northwestern Himalayas in India. Ethnobotanically, it has been used as an ingredient for treatment of bone-joint disorders, impotence and kidney disorders in Kashmir Himalayas. Phytochemically, it is rich in Epimedin ABC and Icariin; all of these have been demonstrated to possess remarkable biological activities like PDE-5 inhibition (treatment of erectile dysfunction), anticancer, antiosteoporosis antioxidant and antiviral properties. The present investigation reports its traditional usage, comprehensive distribution and conservation status from twenty ecogeographical regions in Kashmir Himalayas, India. The species was reported from Gurez valley for the first time. Numerous threats like excessive grazing, deforestration, habitat fragmentation, tourism encroachment, landslides and excessive exploitation have decreased its natural populations in most of the surveyed habitats. Consequently, its existence may become threatened in near future if timely conservation steps are not taken immediately by concerned stakeholders involved in medicinal plant research. Moreover, use of plant tissue culture techniques is recommended for development of its in vitro propagation protocols. Therefore, introduction of this medicinal plant in botanical gardens, protected sites and development of monitoring programmes are needed for its immediate conservation in Northwestern Himalayas, India.

This review summarizes the main topics of our research and covers the period of the last 15 years. The prime interest is focused on various ways of controlling the regio- and stereoselectivity of selected organic reactions, in particular electrophilic additions, cleavage of cyclopropane rings, and allylic substitutions by means of neighboring groups and/or transition and non-transition metals. In the first part, the factors governing the course of electrophilic additions are assessed, culminating in the formulation of selection rules for the reactivity of cyclohexene systems, and in a concise synthesis of the natural cardioactive drug, strophanthidin. These studies also contribute to a better understanding of the mechanisms of electrophilic additions. The second part describes recent developments in the stereo- and regiocontrolled cleavage of cyclopropane rings by non-transition metals (Tl and Hg), and the reactivity and transmetalation (with Pd) of the primary products. This methodology has resulted in novel routes to unique polycyclic structures, and will have synthetic applications in the near future. Evidence for the stereospecific "corner" cleavage of the cyclopropane ring has been provided for the first time for Tl and later for Hg. The third part deals with transition metal-catalyzed allylic substitution. Evidence for a new "syn" mechanism for the formation of the intermediate (π-allyl)palladium complex has been provided, which runs counter to the generally accepted "anti" mechanism. A novel method for a Pd-catalyzed allylic oxidation has been developed and employed in the synthesis of natural sesquiterpenes. The increasing importance of transition and non-transition metals for synthetic organic chemistry is demonstrated by their unique reactivity in a number of the papers included in this review.

Blockchain is a technology that can be applied in different sectors to solve various problems. As a complex system, agribusiness presents many possibilities to take advantage of blockchain technology. The main goal of this paper is to identify the purposes for which blockchain has been applied in the agribusiness sector, for which a PRISMA-based systematic review was carried out. The scientific literature corpus was accessed and selected from Elsevier’s Scopus and ISI of Knowledge’s Web of Science (WoS) platforms, using the PRISMA protocol procedures. Seventy-one articles were selected for analysis. Blockchain application in agribusiness is a novel topic, with the first publication dating from 2016. The technological development prevails more than blockchain applications since it has been addressed mainly in the Computer Sciences and Engineering. Blockchain applications for agribusiness management of financial, energy, logistical, environmental, agricultural, livestock, and industrial purposes have been reported in the literature. The findings suggest that blockchain brings many benefits when used in agribusiness supply chains. We concluded that the research on blockchain applications in agribusiness is only at an early stage, as many prototypes are being developed and tested in the laboratory. In the near future, blockchain will be increasingly applied across all economic sectors, including agribusiness, promoting greater reliability and agility in information with a reduced cost. Several gaps for future studies were observed, with significant value for science, industry, and society.

AbstractThe Sun, as an active star, is the driver of energetic phenomena that structure interplanetary space and affect planetary atmospheres. The effects of Space Weather on Earth and the solar system is of increasing importance as human spaceflight is preparing for lunar and Mars missions. This review is focusing on the solar perspective of the Space Weather relevant phenomena, coronal mass ejections (CMEs), flares, solar energetic particles (SEPs), and solar wind stream interaction regions (SIR). With the advent of the STEREO mission (launched in 2006), literally, new perspectives were provided that enabled for the first time to study coronal structures and the evolution of activity phenomena in three dimensions. New imaging capabilities, covering the entire Sun-Earth distance range, allowed to seamlessly connect CMEs and their interplanetary counterparts measured in-situ (so called ICMEs). This vastly increased our knowledge and understanding of the dynamics of interplanetary space due to solar activity and fostered the development of Space Weather forecasting models. Moreover, we are facing challenging times gathering new data from two extraordinary missions, NASA’s Parker Solar Probe (launched in 2018) and ESA’s Solar Orbiter (launched in 2020), that will in the near future provide more detailed insight into the solar wind evolution and image CMEs from view points never approached before. The current review builds upon the Living Reviews article by Schwenn from 2006, updating on the Space Weather relevant CME-flare-SEP phenomena from the solar perspective, as observed from multiple viewpoints and their concomitant solar surface signatures.

In December 1974, Ian Smith, the leader of the white minority regime in Rhodesia, announced for the first time since declaring his country’s independence from Britain in 1965 that his government was willing to begin direct negotiations with the African liberation movements seeking to achieve majority rule in Rhodesia. The prospect of such talks leading to an end to guerrilla fighting in Rhodesia and a termination of the United Nations authorized sanctions against the illegal Smith regime is dimmed by the fact that the Africans demand African rule for Rhodesia in the near future if not immediately, while Smith and his supporters have refused to consider such a development “in his lifetime.” Still the announcement constituted a step forward which few informed observers would have deemed likely even a few weeks before.

Abstract Harbor Branch Oceanographic Institution (HBOI) designed, built and has operated two JOHNSON-SEA-LINK (JSL) manned submersibles for the past 25 years. The JSL submersibles each incorporate a 66–68 in. (1.6764–1.7272 m) OD, 4–5.25 in. (0.1016–0.13335 m) thick acrylic two-man sphere as a Pressure Vessel for Human Occupancy (PVHO). This type of spherical acrylic sphere or submersible was first introduced in around 1970 and is known as Naval Experimental Manned Observatory (NEMO) submersibles. As the demand increases for ocean exploration to 3000 ft. (914.4 m) depth to collect samples, to study the ocean surfaces, the problem of developing cracks at the interface of these manned acrylic submersibles following few hundred dives have become a common phenomena. This has drawn considerable attentions for reinvestigation of the spherical acrylic submersible in order to overcome this crack generation problem at the interface. Therefore, a new full-scale 3-D nonlinear FEA (Finite Element Analysis) model, similar to the spherical acrylic submersible that HBOI uses for ocean exploration, has been developed for the first time in order to simulate the structural behavior at the interface and throughout the sphere, for better understanding of the mechanical behavior. Variation of the stiffness between dissimilar materials at the interface, lower nylon gasket thickness, over designed aluminum hatch are seemed to be few of the causes for higher stresses within acrylic sphere at the nylon gasket/acrylic interface. Following the basic understanding of the stresses and relative displacements at the interface and within different parts of the submersible, various models have been developed on the basis of different shapes and thickness of nylon gaskets, openings of the acrylic sphere, hatch geometry and its materials, specifically to study their effect on the overall performance of the acrylic submersible. Finally, the new model for acrylic submersible has been developed by redesigning the top aluminum hatch and hatch ring, the sphere openings at both top and bottom, as well as the nylon gasket inserts. Altogether this new design indicates a significant improvement over the existing spherical acrylic submersible by reducing the stresses at the top gasket/acrylic interface considerably. Redesigning of the bottom penetrator plate, at present, is underway. In this paper, results from numerical modeling only are reported in details. Correlation between experimental-numerical modeling results for the new model will be reported in the near future.

Abstract Having previously remained impartial on the Gibraltar question between Spain and Britain since both were member states, the European Union suddenly changed its position after the Brexit referendum in favor of the Spanish government at the expense of breaching international law. In doing so, the European Union, for the first time, created a foreign policy on the long-standing Gibraltar question. This article explores the reasons behind the creation of this foreign policy in support of Spain. The European Union feared that the idea of Euroscepticism may escalate among remaining member states after the Brexit referendum because of wide-spread claims that it would dissolve in the near future, fuelled by farright political parties. The European Union therefore created a foreign policy regarding Gibraltar in Spain’s favor in order to promote a “sense of community” for thwarting a further rise in Euroscepticism. While making its analysis, the article applies the assumption of social constructivism that ideas shape interests, which then determine the foreign policy choices of actors.

Great Honor

On the traditional day of the Kazan Institute for Advanced Training of Physicians, I had the great honor to give an act speech in front of its staff. It was based on the results of scientific works of the staff of the department in 1981-1986 mainly on studying the role of biogenic amines and some hormones (prolactin, hormones of adrenal cortex, parathyroid hormone and calcitonin) in the pathogenesis of some neuroendocrine diseases, which occur in obstetric-gynecological practice.

Clear Information

Abstract Background Only little is information is available about the needs and preferences regarding care and treatment of people who are going through a psychosis for the first time. A first psychotic episode is often an intense experience, which may not directly be recognized as a mental health problem. Given the unfamiliarity with the available options of care, it probably differs from subsequent psychoses. In order to design first psychosis programs to optimally meet patients preferences, we need to learn the care needs of these usually young people. Furthermore, peoples’ needs during the first psychosis, and the need for care after a psychotic episode have to be explored, in order to be able picking up life again after complete or incomplete remission. Methods Qualitative interviews were conducted with people (n = 20) who are in complete or partial remission after their first psychosis about their personal care needs. Interviews were conducted by an experience expert and a researcher together and lasted between 1 and 3 hours. Interviews were non-structured, but a basic set of 5 topics was used. Results Preliminary results of the interviews conducted so far (n = 14) show that people with a first psychosis have a great need for information about the symptoms they are suffering from. In addition, they believe that medication is an important ‘cornerstone’ to get rid of their symptoms. Furthermore, nearly all participants hope to be able to stop medication in the near future. Admission to a ward is in most cases experienced as frightening. One person indicated that the tranquility during admission was very welcome. At this stage, experience experts are not being reached out to yet, nor is there a clear need for social work in this stage of the disease. During and shortly after their first psychosis, the interviewees especially appreciate the support of family and close friends. Discussion Clear information about a first psychosis was mentioned as the first need. Family and close friends are most appreciated as “auxiliary troops”. Family support is therefore an important contributor in care for patients suffering from psychosis. Medication was appreciated as an important cornerstone, but only to induce remission, not as a mean for maintenance treatment. Admission was by most patients experienced as stressful. Additional research is recommended to further map what information this should be exactly, and how to bring it to the patient and his relatives.
