The application of register of patients with diabetes mellitus for verifying causes of death
Authors: Sabgayda Tamara P. , Nikitina S. Yu.
Published: September 2019

The register of patients with diabetes mellitus is appropriate to implement for specification of diagnoses of death of persons registered in this registry. The new version of "The record chart of registration and monitoring of patient with diabetes mellitus" increased information value of register for verifying causes of death at the expense of adding indices of organization of observation of diabetes mellitus and concretization of complications of diabetes mellitus. The information concerning development of complications of diabetes mellitus including the forms the most dangerous for life is very important for rectifying chain ofpathological conditions resulted in death and as a consequence proper determination of initial cause. However, a number of informational and organizational problems are to be resolved to implement information about patients with diabetes mellitus (and other chronic diseases) with purpose of verifying causes of death. First, it is reasonable to make information of specialized registers available to medical specialists providing medical care related to other diseases. The easiest way of searching patient in various registers and data bases is on the basis of one’s personal number of insurance certificate and individual taxation number. The application of two authenticators increases validity of the system of medical information interchange. Second, corrections are to be made in register ofpatients with diabetes mellitus. To correct the record chart of striking individuals with diabetes mellitus off the register can be implemented by two ways. One, to leave empty fields in column "immediate cause of death" and to add subsection "initial cause of death" transferring points of subsection 3.5 to the new subsection. Two, to substitute name of subsection 3.5 with "initial cause of death". Hence, the column "diseases that favored coming of death" is unnecessary in the register of patients with diabetes mellitus.

Published: September 2019

The article considers economic menaces of demographic crisis of human resources in Russia induced by annual reduction of able-bodied population by 1 million. It is demonstrated that one of causes of crisis are cascade reactions due to decreasing fertility by 1 million of children from the early nineties. The inadequacy of common solutions for normalizing of established situation is stated. The possibility of annual increasing of numbers of able-bodied population up to 700-800 thousand is substantiated the expense of decreasing of disability and mortality. The innovative strategy of prevention of non-infectious and occupational diseases is developed based on management of health reserves in individuals with high risk. To implement this strategy a four-stage system ofpersonalized prevention is proposed that is implemented by doctors in polyclinics and by medical social workers in health offices on-the-job places. The important role of trade unions in supporting collective and individual health-improving activities at enterprises.

Authors: Sergeev Boris I. , Kazanets I. E.
Published: September 2019

The migration situation in Russia is characterized by presence of significant number of foreign citizens, including those who are working without official registration and evidence of examination for tuberculosis and other infections. In connection with that, attention is to be paid to propositions concerning organization of preventive examination for tuberculosis in the departure country i.e. medical examination of potential migrants according Russian standards on the basis of local medical institutions. The article presents review of data of official statistics concerning migration and prevalence of tuberculosis including scientific publications about analysis of international experience of organization and implementation of preventive examinations in the departure countries. The experience of implementation of medical examinations of migrants in number of departure countries demonstrates that these programs permit focusing efforts on diagnostic of tuberculosis in one of risk groups hence achieving comparatively high degree of reliability of results and providing economic significance. In the context of conditions in Russia and accounting international experience two scenarios are proposed of implementing preventive examinations for tuberculosis in departure countries: with and without introduction of requirement of preliminary medical inspection of working migrants.

The study was carried out to establish hygienic estimate of labor employment and its effect of health of adolescents in various regions of Russia. The questionnaire survey of 1 500 individuals (senior high school students and students of professional education colleges) was implemented in four regions of the Russian Federation (Moscow, St. Petersburg, Omsk and Pskovsk regions). The quality of life related to health was estimated using standard questionnaire MOS SF-36. It is established that 41.2% of adolescents worked during time free of lessons. In Moscow, number of working adolescents is reliably lower than in other regions (32.8%). The prevalence of illegal labor activity in all oblasts is demonstrated. The regional features of of structure of labor employment according types of work and causes of labor activity is established. The study confirmed that labor activity in adolescent age is a health risk factor. The analysis of health risks demonstrated that in adolescents working all days of week during academic year are established risks of health complaints: leg pains (OR = 2.1, RR = 1.7, EF = 39.4%) in St. Petersburg, back pains (OR = 1.9, RR = 1.5, EF = 35.2%) in Omsk, heartburn (OR = 2.1, RR = 2.4, EF = 44.5%) and other disorders of digestion (OR = 2.4, RR = 1.9, EF = 48.4%) in Pskov. The increased risks are established in adolescents permanently working during academic year: occurrence of health complaints (OR = 2.6, RR = 1.6, EF = 38.8%) in Pskov, complaints on leg pains (OR = 3.2, RR = 2, EF = 49.5%) in Moscow, heartburn (OR = 4.7, RR = 3.4, EF = 70.5%) in Omsk, other disorders of digestion (OR = 4.3, RR = 2.8, EF = 64.4%) in Pskov. In these groups of working adolescents lower levels of indicator of quality of life related to health (according MOS SF-36) - BP scale (pain intensity) are established.

Published: September 2019

In 2014, increasing of mortality is observed in the Republic of Crimea. The attempts to normalize situation using common preventive means turned out to be not enough effective. The purpose of study is to analyze causes of deterioration of demographic situation and to substantiate measures of efficacious prevention. The data of state statistics was used as a primary material. The mortality of main non-infectious diseases prevailed in the structure of human losses. However, its dependence on classical risk factors had no factual confirmation. The ecological situation ameliorated. The health care system maintained a needed stability. The deterioration of psychic condition of population was detected. The suggestion was expressed concerning its effect on somatic reserves of health. In conditions of etiological uncertainty of mortality decreasing a personalized prevention was proposed targeting management of health reserves under control of personal risks. The percentage of Crimea population with redundant lethal risk makes up to no more than 5%. The modernization of actual dispensarization system is proposed to detecting and health improving them. The working population is proposed to pass screening examination without breaking labor process on the basis of health posts (health room) of enterprises. The traveling diagnostic teams can be used. The idle population is examined in the departments of prevention in polyclinics. The low cost prognostic technologies are used. The selection of individually efficient health promoting measures requires long work with patient. to implement this approach a third stage of dispensarization is proposed using innovative health promoting technologies. The medical social workers are involved into this activity. The trade union organizations can play an important role in the prevention system functioning. The particular attention is paid to using health promoting possibilities of recreation institution of Crimea.

Inguinal hernia containing bladder is an uncommon and usually
asymptomatic condition that occurs at the inguinal canal, scrotal sac or
femoral canal. Incidentally detection of inguinal hernia of bladder by bone scintigraphy
has been rarely presented in the literature and usually verified by CT or
ultrasonography. Single photon emission computed tomography/computed tomography
(SPECT/CT) is helpful to evaluate and locate precisely an area of abnormal
activity that can be present on the planar scintigraphy.

In this report, we aimed to describe a case of inguinoscrotal bladder
herniation diagnosed by SPECT/CT that is mimicking pubic bone metastasis on
bone scintigraphy in a 65-year-old male patient with prostate cancer.
Spatiotemporal coordinates of the artistic world of N. Abgaryan in the storybook “To live further”
Authors: Kuzminykh Elena O. , Vyazovskaya Victoria V.
Published: September 2019

We present the study of spatiotemporal coordinates of the artistic world of N. Abgaryan in the storybook “To live further”, which was not previously the subject of keen interest of re-searchers. The purpose of the study is to conduct a comprehensive analysis of the texts of story-book “To live further” as a whole, identifying the features of the writer’s artistic world through the revealing of its main spatiotemporal categories. We show that the main chronotopes in the studied storybook are “house” and “provincial city of Berd”, the locus of which are closely interrelated and perceived as the world. The key concepts for understanding the artistic world of N. Abgaryan are cultural and ancestral memory, the eternal cycle of existence. The restoration of the war-torn time cycle becomes possible thanks to the activation of cultural memory mechanisms. Ways to restore the cyclic time, disturbed by the war, in the studied storybook is the repeatability of ordinary actions. Actualization of memory is carried out through the thing, name, smell, food. Preservation of memory is associated with changes in the flow of biological time. The silence chosen by N. Abgaryan’s heroes is not only a way of displacing tragic events from memory, but also a new opportunity to experience memories. The emblematic title of the storybook “To live further” leads the reader to the idea that life always defeats death, and the cyclicity of time is the key to world harmony.

Published: September 2019

A Base Nacional Comum Curricular homologada pelo Ministério da Educação em 2017 apresenta temas de Ciências da Terra que devem ser desenvolvidos em todos os anos do ensino fundamental. Entretanto, estudos identificam insuficiência de conteúdos de Ciências da Terra nos currículos da formação inicial de Pedagogos, que geralmente lecionam do 1º ao 5º ano do ensino fundamental, e de professores de Ciências da Natureza, que lecionam do 6º ao 9º ano do mesmo ciclo da educação básica. Assim, é necessário complementar a formação inicial de professores. Uma alternativa são os cursos de extensão, que fortaleceriam o conhecimento acadêmico dos docentes. Este trabalho objetiva descrever uma proposta de curso de aperfeiçoamento, na modalidade extensão universitária semipresencial, focalizando temas fundamentais de Ciências da Terra. O curso se destina a professores que lecionam Ciências da Natureza no ensino fundamental.

Published: September 2019

The prevalence of congenital hearing impairment (HI) is highest in Africa. Estimates evaluated genetic causes to account for 31% of HI cases in Africa, but the identification of associated causative genes mutations have been challenging. In this study, we reviewed the potential roles, in humans, of 38 novel genes identified in a murine study. We gathered information from various genomic annotation databases and performed functional enrichment analysis using online resources i.e. genemania and g.proflier. Results revealed that 27/38 genes are express mostly in the brain, suggesting additional cognitive roles. Indeed, HERC1- R3250X had been associated with intellectual disability in a Moroccan family. A homozygous 216-bp deletion in KLC2 was found in two siblings of Egyptian descent with spastic paraplegia. Up to 27/38 murine genes have link to at least a disease, and the commonest mode of inheritance is autosomal recessive (n=8). Network analysis indicates that 20 other genes have intermediate and biological links to the novel genes, suggesting their possible roles in HI. This study will contribute to advance our knowledge in unravelling the biological roles of novel murine HI genes in humans and could enhance the understanding of the genetic causes of HI in Africans.
Computational Modeling of Tensile Stress Effects on the Structure and Stability of Prototypical Covalent and Layered Materials

Published: September 2019

Understanding the stability limit of crystalline materials under variable tensile stress conditions is of capital interest for their technological applications. In this study, we present results from first-principles density functional theory calculations that quantitatively account for the response of selected covalent and layered materials to general stress conditions. In particular, we have evaluated the ideal strength along the main crystallographic directions of 3C and 2H polytypes of SiC, hexagonal ABA stacking of graphite and 2H-MoS2. Transverse superimposed stress on the tensile stress was taken into account in order to evaluate how the critical strength is affected by these multi-load conditions. In general, increasing transverse stress from negative to positive values leads to the expected decreasing of the critical strength. Few exceptions found in the compressive stress region correlate with the trends in the density of bonds along the directions with the unexpected behavior. In addition, we propose a modified spinodal equation of state able to accurately describe the calculated stress-strain curves. This analytical function is of general use and can also be applied to experimental data anticipating critical strengths and strains values and providing informattion on the energy stored in tensile stress processes.
Circadian Tuning with Metameric Wite Light: Visual and non-visual Aspects
Authors: Aderneuer Tamara , Stefani Oliver , Fernández Oscar , Cajochen Christian , Ferrini Rolando
Published: September 2019

The growing awareness of the biological effects of artificial light on humans has stimulated ample research. It is now widely accepted that asynchrony between artificialand natural light-dark cycles can elicit severe detrimental health effects. New research has been devoted to lighting solutions that dynamically change their color to mimic spectral changes of daylight and to account for human needs. However, in some situations, the visual properties of light must be preserved: For example professional TV video editors and shift workers who must work under standardized lighting conditions to do color correction in post-production. We have investigated the possibility to tune circadian effects using white lights that are spectrally different but nonetheless have similar color coordinates thus appear as a similar white tone. Our simulation results indicate that it is possible to modulate circadian light effects by combining LEDs for neutral white (4000 K), a widely used white tone for indoor lighting in europe. The results also show that the solutions combining single-color LEDs do however not meet the quality criteria from the visual point of view because their color rendering ability decays to unacceptable low levels. Combining narrowband LEDs with a broadband white LED improves the color rendering quality and we show how far circadian light effects can be tuned according to common theoretical models. The aim is to reflect daylight situations with artificial lighting, thus having a high melatonin suppression in the morning and low melatonin suppression in the evening. As a consequence our aim is to show what maximum and minimum circadian effect is possible with the same set of LEDs.
An Economic Examination of Collateralization in Different Financial Markets
Authors: Xiao Tim
Published: September 2019

This paper attempts to assess the economic significance and implications of collateralization in different financial markets, which is essentially a matter of theoretical justification and empirical verification. We present a comprehensive theoretical framework that allows for collateralization adhering to bankruptcy laws. As such, the model can back out differences in asset prices due to collateralized counterparty risk. This framework is very useful for pricing outstanding defaultable financial contracts. By using a unique data set, we are able to achieve a clean decomposition of prices into their credit risk factors. We find empirical evidence that counterparty risk is not overly important in credit-related spreads. Only the joint effects of collateralization and credit risk can sufficiently explain unsecured credit costs. This finding suggests that failure to properly account for collateralization may result in significant mispricing of financial contracts. We also analyze the difference between cleared and OTC markets.

Authors: Mihata Teruhisa , Lee Thay Q. , Hasegawa Akihiko , Fukunishi Kunimoto , Kawakami Takeshi , Fujisawa Yukitaka , Ohue Mutsumi , Neo Masashi
Published: September 2019

Background:

Arthroscopic superior capsule reconstruction was developed to restore superior stability, muscle balance, and function in the shoulder joint after an irreparable rotator cuff tear. Our objective was to assess the functional and radiographic results of superior capsule reconstruction after 5 years of follow-up.

Methods:

Thirty patients who underwent arthroscopic superior capsule reconstruction using fascia lata autograft were enrolled in this study. The inclusion criteria were an irreparable rotator cuff tear confirmed by shoulder arthroscopy and 5 years of postoperative follow-up. Shoulder range of motion, American Shoulder and Elbow Surgeons (ASES) and Japanese Orthopaedic Association (JOA) scores, rates of return to sport and physical work, acromiohumeral distance, Goutallier grade of all rotator cuff muscles, graft healing and thickness, and postoperative cuff tear arthropathy were investigated.

Results:

Compared with preoperative values, ASES and JOA scores, active elevation, and acromiohumeral distance increased postoperatively at both 1 year (p < 0.001) and 5 years (p < 0.001); the 1-year values increased by 54.0 points for the ASES score, 34.4 points for the JOA score, 53° for active elevation, and 5.7 mm for acromiohumeral distance, and the 5-year values increased by 63.3 points for the ASES score, 39.9 points for the JOA score, 66° for active elevation, and 4.7 mm for acromiohumeral distance. The ASES score was greater at 5 years postoperatively than it was at 1 year postoperatively (mean difference, 9.3 points; p = 0.03). At 5 years postoperatively, 11 of 12 patients returned to physical work, a rate of 92% (95% confidence interval [CI], 73% to 100%), and 8 of 8 patients returned to sports, a rate of 100% (95% CI, 79% to 100%). None of the 27 patients who had graft healing showed progression of cuff tear arthropathy, but all 3 patients with a graft tear (10% [95% CI, 0% to 22%]) had severe cuff tear arthropathy at 5 years postoperatively. In the 27 patients whose grafts remained intact, the graft thicknesses at 3 months, 1 year, and 5 years postoperatively did not differ (p = 0.67).

Conclusions:

In this 5-year follow-up study, healed arthroscopic superior capsule reconstruction restored shoulder function and resulted in high rates of return to recreational sport and work. In patients with postoperative graft failure, severe cuff tear arthropathy was present at 5 years.

Randomized Controlled Trials for Geriatric Hip Fracture Are Rare and Underpowered
Authors: Bernstein Joseph , Weintraub Sara , Morris Tyler , Ahn Jaimo
Published: September 2019

Background:

Geriatric hip fracture is a common condition, and there are many open questions regarding patient management. Among the various types of medical evidence, the prospective randomized controlled trial (RCT) is considered the best. Our primary hypothesis was that small sample size would be seen frequently among RCTs involving geriatric patients with hip fracture. A related hypothesis was that studies from the United States would have particularly large deficits in sample size. Therefore, we asked the following research questions: (1) What is the mean sample size of RCTs involving geriatric patients with hip fracture? (2) How do sample sizes for studies from the U.S. differ from those performed elsewhere?

Methods:

Following the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines, a systematic review of hip fracture RCTs was conducted. The Embase and MEDLINE databases were searched. Additional data included the country of origin, the power of the study, and whether sample size calculations were performed. One hundred and forty-seven RCTs were identified.

Results:

The mean sample size of the 147 RCTs was 134.9. The mean sample size for the 7 American trials was 110.3, and the mean sample size for all trials conducted outside of the United States was 136.1. A sample size that was sufficient to ensure 80% power was used in only 31.3% of the RCTs.

Conclusions:

RCTs for hip fracture are small and underpowered. Moreover, <5% of the RCT studies have been conducted in the U.S., and they were smaller than those conducted elsewhere. The shortage of American trials may be a feature of the dispersion of geriatric hip fracture care across many hospitals in the United States. If so, better clinical research might require more centralized care (e.g., in specialized geriatric hip fracture centers) or greater collaboration among the many hospitals that provide care.
Cervical Cord Injury Following Posterior Spinal Fusion in a Patient With Adolescent Idiopathic Scoliosis
Authors: Kristobak Anne , Helgeson Melvin D. , Jex Jefferson
Published: September 2019

Case:

We present an 11-year-old girl with adolescent idiopathic scoliosis who underwent uncomplicated posterior spinal fusion and developed transient upper extremity weakness secondary to a cervical cord injury several hours after the conclusion of the case.

Conclusions:

Perioperative hypotension, positioning, and mild cervical canal stenosis contributed to cervical cord injury following posterior thoracic instrumentation. Optimal perioperative resuscitation and awareness of cervical spine anatomy along with proper positioning may prevent this rare but potentially serious complication.
Scurvy Findings in a Child with Jacobsen Syndrome
Authors: Puddy Alan C. , Hughes Jessica L. , Joffe Avrum L. , Khanna Paritosh C. , Thornburg Courtney D. , Mubarak Scott J.
Published: September 2019

Case:

We describe the first reported case of scurvy developing secondary to behavioral traits of Jacobsen syndrome. The diagnosis of scurvy was significantly delayed because bleeding symptoms were initially attributed to baseline thrombocytopenia and platelet dysfunction associated with Jacobsen syndrome and patient's medication. Following vitamin C supplementation, signs and symptoms of the patient's disease quickly resolved.

Conclusions:

We aim to reinforce the need to consider nutritional deficiencies in patients with complex medical histories and behavioral issues, especially when presenting with new complaints.
A Locked Sacroiliac Joint Dislocation Requiring Open Reduction
Authors: Yarboro Seth R. , Hadeed Michael M , Vess Eric M. , Weiss David B.
Published: September 2019

Case:

Vertically unstable pelvic ring injuries are often associated with sacroiliac (SI) joint subluxations or dislocations. The following report describes an irreducible SI joint dislocation where the ilium was locked in a position superior to the sacrum. This injury was refractory to initial closed reduction techniques and ultimately required an open reduction.

Conclusions:

This report demonstrates the limitations of closed manipulation for some vertically unstable pelvic ring injuries. It is critical to have a strong understanding of the anatomy and typical manipulations to succeed in both closed and open SI joint reduction attempts.
Brachial Plexus Injuries Associated With Open Subpectoral Biceps Tenodesis
Authors: Ransom Erin F. , Ficke Brooks , Ponce Brent A. , Meyer Richard D.
Published: September 2019

Case:

We report 2 cases of brachial plexus injury after open subpectoral biceps tenodesis. In 1 patient, the nerves likely sustained a stretch injury related to retractor use. In the other patient, multiple nerves were severed, and we hypothesize that they were caught in a drill bit.

Conclusions:

To decrease the risk of nerve injury due to traction or inadvertent wrapping of nerves in the drill bit or tenodesis screw, we recommend careful retractor use and tendon fixation techniques that use a protective sleeve during both drilling and fixation.

Published: September 2019

Background . Patients with chronic kidney disease, including these after kidney transplantation (KTx), have higher cardiovascular mortality. Global longitudinal strain (GLS) detects subtle changes in the left ventricle (LV) and is more sensitive predictor of cardiovascular mortality than the LV ejection fraction (LVEF).The aim of this study was to assess the prevalence of impaired GLS among kidney transplant recipients with preserved LVEF. We also aimed to identify possible clinical factors responsible for GLS impairment.
Methods . A total of 79 patients following KTx with preserved LVEF and no history of cardiac disease were evaluated. We assessed echocardiogram parameters with the calculation of GLS, laboratory parameters, presence of diabetes, hypertension, duration of haemodialysis (HD) and time after KTx. An impaired GLS value was set on ≥-18%. The Classification and Regression Trees and stepwise logistic regression analysis were used to identify the factors related to impaired GLS.
Results. Among 79 (42 females, mean age 60.3) kidney transplant recipients with preserved LVEF, 39% had impaired GLS. In stepwise logistic regression analysis, two variables related with GLS≥-18%: duration of HD before KTx longer than 27.5 months (OR 4.48, 95% CI 1.46-14.38, P=0.01), and eGFR greater than 60mL/min/1.73m2 (OR 0.155, 95% CI 0.024-0.967, P= 0.049).
Conclusions. In our study group, a total of 39% of KTx patients with preserved LVEF had impaired GLS. The main risk factor of GLS impairment was the prolonged time of HD (>27.5 months) prior to KTx, whereas a good renal graft function (eGFR>60mL/min/1.73m2) only marginally proved to be a protective factor.

Published: September 2019

Background : The data of Brucella endocarditis is relatively little. This study was to summarize the characteristics of epidemiology and clinical features of brucella endocarditis.
Methods: 23 patients with brucella endocarditis collected in our hospital from July 2007 to August 2018 were analyzed.
Results: Among the patients, 91.3% was male, the age was 42.6±12.4 years old. 69.6% patients had contacted with cattle and sheep. The most common symptom in these patients was chest tightness (60.8%), shortness of breath (60.8%), fever (43.5%) and anemia (43.5%). In the patients with anemia, 50% also had a lower platelet (including one patient had lower leucocyte level). Blood culture before taking antibiotics is easy to find Brucella sp . The aortic valve (91.3%) is most commonly involved, followed by mitral valve (17.4%) and tricuspid valve (8.7%). 87.0% of patients followed with complications, including cardiac failure (73.9%), pulmonary infection (43.5%), hydropericardium (34.8%), renal insufficiency (21.7%), multiple organ disfunction (4.3%), bacterial aneurysm rupture (4.3%), paravertebral abscess (4.3%), cerebral infarction (4.3%), pericardial stenosis and adhesion (4.3%). 47.8% of patients exhibited hyperglobulinemia and 80% of patients with renal insufficiency had hyperglobulinemia. 22 patients had suffered antibiotics and surgery treatment and one patient gave up treatment. 2 patients (8.7%) died because of ventricular fibrillation and refractory heart failure.
Conclusion: Brucella endocarditis was a complex disease and could lead to multiple organ disfunction. Cardiac failure was the main reason for death and the mortality was 8.7%.
Identifying Opportunities to Promote Water Treatment Practices among Nursery and Greenhouse Growers

Published: September 2019

There are many water treatment technologies available to the nursery and greenhouse industry, but this sector has been somewhat hesitant to adopt them. An online survey was used to evaluate nursery and greenhouse growers’ knowledge, implementation, and continued use of 12 water treatment technologies. Less than 24% of the growers had used a water treatment technology. The knowledge level was low overall, and fewer than one in four growers had implemented all 12 technologies. However, most growers who had implemented 10 of the 12 technologies continued to use them. The results imply water treatment technologies available for this group are somewhat unknown and underused, thereby implying that there is a need to increase awareness of these innovations and highlight the opportunity for growers to advocate for treatment technology use among their peers.
Prairie Dropseed Germination Highest with Warm, Moist Conditions
Authors: Meyer Mary Hockenberry , Narem Diane M.
Published: September 2019

We tested prairie dropseed (Sporobolus heterolepis) using six different germination treatments and found the best results with cold (40 °F), dry storage followed by direct seeding into a commercial germination mix placed in a 75 °F glass-glazed greenhouse with intermittent mist (5 seconds of mist every 8 minutes), and 600-W high-pressure sodium lighting with a 16-hour daylength. We found commercial laboratory viability analysis from tetrazolium staining did not correspond to germination results. Cold (34 °F), moist (2.3 g seed moistened with 2.5 mL deionized water) treatment, also known as cold conditioning, produced significantly less germination and fewer transplantable seedlings, and is not recommended for prairie dropseed.

Published: September 2019

A new type of magnonic crystals, curvature induced ones, is realized
in ferromagnetic nanowires with periodically deformed shape. A magnon
band structure of such crystal is fully determined by its curvature: the
developed theory is well confirmed by simulations. An application to
nanoscale spintronic devises with the geometrically tunable parameters
is proposed, namely, to filter elements.
