The Federal Reserve Board’s Survey of Consumer Finances for 2019 provides insights into the evolution of family income and net worth since the previous time the survey was conducted in 2016. The survey shows that over the 2016–19 period, the median value of real (inflation-adjusted) family income before taxes rose 5 percent, and mean income decreased 3 percent. Real median net worth increased 18 percent, and mean net worth rose 2 percent. This survey marks the first in the aftermath of the Great Recession in which between-survey changes in the median outpaced changes in the mean for either measure, indicating that families in large parts of both distributions enjoyed gains in economic well-being. And, while the data also reveal some disparities in the evolution of income and net worth since 2016 across families differentiated by economic characteristics, such as income or wealth, and demographic characteristics, such as age, education, or race and ethnicity, many groups with historically lower income and net worth saw relatively large gains. This article reviews these and other changes in the financial condition of U.S. families, including developments in assets, liabilities, debt payments, and credit market experiences. The findings in this article do not reflect the effects of the COVID-19 pandemic on family finances, as almost all of the data in the 2019 survey were collected before the onset of the pandemic.

One of the main places in the selection of grapes today belongs to native varieties. Native varieties possess characteristics valuable in economic relations, such as a high-quality berry crop, from which it is subsequently possible to obtain the highest quality wine, as well as resistance to harsh climatic conditions. However, before starting breeding work, it is necessary to conduct various pre-breeding studies, including genetic analysis. This type of analysis is the most informative of all, because it gives the most complete picture of all the genetic predispositions of any organism, as well as what potential the specific varieties possess. The analysis is carried out using a variety of molecular genetic markers, which include IPBS markers. The mechanism of their action is based on the use of primers for PBS retrotransposon sequences (Primer binding site, tRNA binding site). This choice is due to the fact that IPBS markers perform well when detecting polymorphism between samples, which include both varieties and clones of varieties. As a result, the following DNA markers were used: iPBS2074, iPBS2230, iPBS2415, Vine-1, and the following indigenous grape varieties: Kumshatsky, Varyushkin, 9th row of class 19, Chilyaki 1-23 (35-36), Cinnamon white mutation, Slitny, Decent , Augustine, Yay raisin white, Kishmish oval white, (Sultanina), Yay raisin pink, Kishmish red Turkmen (Sultatnina pink), Tsimlyansky black. Based on the results of all the studies, namely polyacrylamide gel electrophoresis (PAGE), interpretation of the obtained photos, and subsequent data processing in Microsoft Excel using the GenAlEx 6.3 macro, analysis in AMOVA, and MEGA7 with UPGMA parameters, the conclusions were made that molecular markers of IPBS were effective in preselection studies of the native grape varieties.

Soybean is one of the most valuable protein crops on the modern market of agricultural producers and its production has been constantly growing in recent decades. The level of its productivity, as well as any other crop, depends on the biological productivity potential of the cultivated variety and the degree of implementation of its cultivation techniques. The aim of the research was to study the responses of soybean Glycine max (L.) Merr. Zusha varieties for various mineral nutrition in the conditions of agrocenosis. The research was conducted on the basis of the research and educational production center "Integration" of the Orel State Agrarian University named after N.V. Parakhin. We determined the biological efficiency of fertilizer systems, the productivity and quality of grain under different mineral nutrition conditions .Testing of liquid complex fertilizers on soy has shown high biological and economic efficiency of mineral fertilizers. In conditions of dark gray forest soils with average agrochemical indicators of the soil, as well as with spontaneous inoculation of soybean by native rhizobia strains, the maximum economic effect was demonstrated with the pre-sowing application of complex mineral fertilizer NPK (S)+Ca 5:15:30(5)+7 in a dose of 150 kg/ha and 20 kg/ha of urea, as well as diammofoski NPK(S) 10:26:26 (2) in conjunction with the ZhCU. The use of mineral fertilizers contributed to an increase in the growth of biomass by an average of 23%, and the area of leaves-by 8.5% compared to the control. Changes in mineral nutrition led to an increase in the content of raw protein in soy grains. Additionally, 4.4-4.6 C/ha of grain was obtained from 1 ha, respectively 4.7 and 5.4 thousand rubles of income due to an increase in soybean productivity by 22-23% compared to the control.

Background/Objectives: Game-Based Learning (GBL) is an emerging term that has attained focus and appreciation at a remarkable level these days, the GBL plays a significant role to learn through games. Angry Birds (AB) is one of the games which are very popular among kids that they mostly spend more than 8 hours of the whole day to play this game. AB’s popularity among the kids is due to its user-friendly easy interface and easy rules. Interface and rules of the game reveal primary physics theories and concepts. This study is conducted to modify the AB interface in such a way that basic physics concepts can be taught to secondary school students using this Game Based Tool (GBT). The objective is to provide GBL tool to teachers and students. That will be helpful for teachers to teach the physics concepts in an interesting way to students.Methods/Statistical analysis: The interface of the AB game is modified in such a way that while students perform various actions to kill the targeted pigs, to hit the objects for scoring, they will be able to learn physics, i.e., projectile motion and some basic concepts of physics involved in achieving the goals. This paper will present the modified interface of AB and how that is used for physics learning. This study is carried to attempt the mentioned objective. The experiment was conducted on 80 students of secondary school,i.e. group 1 played traditional AB game and learned physics in classroom without gaming aid and group 2 learned physics theories in class and used the modified AB game for playing game additionally learned physics from the actions they performed during play. Findings: This study shown that simple and interesting games can be used for learning scientific theories for secondary school students.

Authors: Damaianti Vismaia Sabariah , Abidin Yunus , Rahma Rosita
Published: October 2020

Learning theories have seen the development of students’ higher order thinking skills a quintessential educational goal for all students, as the absence of such skills in learning leads to students’ difficulty in answering questions that are analytical, critical, creative, and problem-solving. What is more, the prevailing literacy scoring instruments have yet to take into account the Indonesian cultural context despite the fact that culture is such an important vehicle in strengthening the identity of a nation. In order to address this problem, employing a research-and-development method, a HOTS-based reading literacy scoring device model was proposed in this research. In the development stage, the model was tested to 476 junior high school students in two separate islands in Indonesia: Java and Bali. The results of the qualitative assessment from the experts showed that the product developed in principle had fulfilled the requirements. Meanwhile, the validity and reliability test results demonstrated that the instrument under investigation had met the requirements as a standardized reading literacy assessment product.  Implicationally, therefore, the proposed model can be utilized in assessing students’ reading skill in Indonesian contexts.

Estimating photosynthetic pigments, such as chlorophylls, as well as the foliar nitrogen content is very important for the evaluation of the nutritional and physiological status of a plant. However, producers cannot easily carry out these estimations because they involve analyses in laboratories that are costly and time-consuming. The SPAD-502 total chlorophyll index meter is efficient at rapidly estimating total chlorophyll contents in situ, along with its relationship with the total nitrogen concentration in tissues. The objective of this research was to validate a non-destructive in situ method (SPAD) for use in place of destructive estimation methods for chlorophylls a, b and total, as well as the foliar nitrogen concentration in guava plants (Pisium guajaba L.), cv. Regional Roja, in three phenological stages under the conditions of the municipality of Vélez-Santander (Colombia). The data obtained with the SPAD-502 and the content of chlorophylls a, b and total were adjusted to a second-degree polynomial with correlation coefficients (r) greater than 0.91 for the three phenological stages, while the concentration of foliar nitrogen was adjusted to a linear type model with determination coefficients (R2) higher than 0.90, indicating a highly linear correlation between the non-destructive method and the destructive methods used in the present study.

Published: October 2020

Osteosynthesis with LISS system (less invasive stabilization system) is a new technology and this conception of stabilization of long bone fragments is a new step in the development of AO philosophy. Indications to application of this system are distal metaepiphysis and diaphysis femur fractures, supra- and transcondylar fractures in polytrauma, fractures in osteoporosis as well as fractures after total knee replacement. During the last 3 years 35 patients were operated on by that technique. The follow-up period ranged from 6 months to 3 years. Assessment of outcomes was performed using data of clinical examination and evaluation of radiograms with modified Neer-Grantham-Shelton scale. In patients who were operated on 1 year ago the total score varied from 70 to 80 (maximum 100). Advantages of this technology as compared to the traditional methods of osteosynthesis are the following: limited operative trauma, less blood loss, shortening of surgery duration, preservation of tissue physiology as well as absence of the necessity to use cement and bone auto- and allografts. Disadvantages include the difficulty for reposition prior to fixation and impossibility of correction in postoperative period as well as early weight-bearing load.

Authors: Lazarev A. F. , Solod E. I.
Published: October 2020

Special method of strained osteosynthesis for proximal humerus fractures is suggested. Twenty patients, aged 52- 78 years, were operated on by that technique. Primary stiffness of fixator (Y-shape pin) and secondary stiffness created by insertion and blocking of that pin provide stable fixation of fragments without infliction of additional intraoperative trauma. Owing to that the operative method could be successfully used in all patients with proximal humerus fractures independently on patients age and general condition. Preservation of blood circulation in the fragments, light traumatization of osteosynthesis, possibility of early rehabilitation makes this method perspective for the treatment of fractures in osteoporosis. Efficacy of drug therapy for osteoporosis during postoperative period is shown.

On the base of experience in treatment of 114 patients with concomitant and multiple injury (1996-2003) the indications, terms and tactics of operative intervention in complicated comminuted fractures of distal femur were determined. During resuscitation period in open fractures primary debridment and stabilization with external fixation devices was performed. In closed fractures immobilization by skeletal traction; in movement irritation - by external fixation device was used. At 10-21 day after trauma deep osteosynthesis with fixatives (angular plate - 51 fractures, condylar plate - 30 fractures, DCS - 6 fractures, DCP - 18 fractures) was carried out. In presence of other fractures of ipsilateral and contralateral limb the modem fixatives (DFN - 4 cases, UFN - 3 cases) were used. Application of low invasive technique allowed to perform the osteosynthesis of all fractures simultaneously. Long term results were evaluated in 53 patients (59 distal femurfractures) atfollow up 1-6 years. Excellent results were achieved in 30 (50,8%), good - in 14 (23,7%), satisfactory - in 7(11,9%) and unsatisfactory - in 8 (13,6%) cases.

Published: October 2020

Guided growth technique with temporary epiphysiodesis is used for the correction of lower extremities axial deformities in children before skeletal maturity. From 2009 to 2013 one hundred fifty epiphysiodesis procedures were performed in 93 children aged 3–15 years. Technique was performed both in patients with idiopathic deformities and in patients with severe systemic pathology (skeletal dysplasias, neuromuscular disorders, metabolic nephropathies). Treatment results were assessed at terms from 12 to 48 months after surgical intervention. Good results were achieved in 67 (72%), satisfactory — in 18 (19.3) and poor — in 8 (8.6%) patients. Mean rate of correction made up 0.81±0.17° per 1 month of epiphyseodesis with its maximum in valgus knee and ankle deformities. Advantages of the procedure included low invasiveness and simplicity of performance, low complication rate, possibility of simultaneous intervention on several levels as well as combination with other interventions. Thorough selection of patients, proper intervention technique and regular postoperative followup enable to avoid complications and unsatisfactory results.

Published: October 2020

The most physiologic and low invasive method for reduction of anterior shoulder dislocation is Dzhanelidze technique that has been proposed in about 100 years ago. However this technique is not often applied in practical work. The authors have analyzed the efficacy of original Dzhanelidze technique at treatment of 6 patients and its popularity among practical trauma- and orthopaedic surgeons (n=54) from different hospitals in Vladivostok and Primorski Territory. It is shown that original shoulder dislocation reduction technique by Dzhanelidze without morphine use is not effective. Out of all surgeons who participated in questionnaire survey only 10 (18.5%) specialists apply Dzhanelidze method in practice. Physicians use various modifications of this method that considerably differ from the original technique. Description of Dzhanelidze technique in modern textbooks and manuals of surgery and traumatology are contradictory and significantly differ from the author’s technique.

The study was based on the results of 2620 surgical interventions (2911 operations, out of them 1512 - with ESI, 1399 - with Zimmer implants) performed in two independent clinics. Revision intervention due to aseptic loosening of implant components was required in 62 (ESI) and 66 (Zimmer) cases and the terms of that complication development were practically the same. In 5 to 8 years after operation excellent, good and satisfactory results (70 - 100 points by Harris) were observed in 95.2% of patients operated on using ESI implants and in 94.8% of patients - with Zimmer implants. In 10 - 14 years the indices made up 89.2 and 88.2%, respectively. Thus, the results of different implants application were comparable

The ability to calculate the seismogram of an earthquake at a local or regional scale is critical but challenging for many seismological studies because detailed knowledge about the 3D heterogeneities in the Earth’s subsurface, although essential, is often insufficient. Here, we present an application of compressed sensing technology that can help predict the seismograms of earthquakes at any position using data from past events randomly distributed in the same area in Jinggu County, Yunnan, China. This first data-driven approach for calculating seismograms generates a large dataset in 3D with a volume encompassing an active fault zone. The input number of earthquakes comprises only 1.27% of the total output events. We use the output data to create a database intended to find the best-matching waveform of a new event by applying an earthquake search engine, which instantly reveals the hypocenter and focal-mechanism solution.

Systemic lupus erythematosus (SLE) is a systemic autoimmune disease with various clinical manifestations affecting different tissues. Pro-inflammatory cytokines, such as interleukin 1β, IL-6 and IFN-g are associated with the SLE progression; however, the precise molecular mechanisms that in occurs improper cytokines production in SLE remain unknown. Autoantibody production and renal disease were evaluated in NZB/W F1 mice treated with a specific Pin1 inhibitor, Juglone. Inhibition of Pin1 activity significantly suppressed the IL-6 expression in NZB/W F1 mice and developed milder renal lesions than the lesions developing in non Juglone-treated mice. We further found that Pin1 inhibitor treatment suppresses B-cell differentiation and T-cell activation in NZB/W F1 lupus mice. Finally, stat3 phosphorylation was decreased in T cells from Pin1inhibitor-treated mice at 40 weeks of age as compared to that from the saline and isotype control mAb treatment groups. This is the first study to demonstrate that Pin1 plays critical roles in SLE development. Pin1 inhibition to the appropriate level might provide a novel therapeutic strategy target for future SLE therapies.

As pilhas e baterias são os dispositivos de acumulação de energia mais utilizados. Assim, tem-se estudado diferentes alternativas como forma de melhorar propriedades desses sistemas. A inserção de aditivos na composição do material ativo das placas de baterias chumbo-ácido, tem sido conceituada como uma das alternativas para promover tal melhora. Desse modo, o presente trabalho se propõe a avaliar a influência da inserção de aditivos de carbono na forma de grafite na morfologia das placas de baterias chumbo-ácido. Tendo em vista os resultados obtidos, conclui-se que a macroporosidade possui uma relação inversamente proporcional com a densidade aparente e que a morfologia e cor da superfície do material são drasticamente modificados com o aumento do conteúdo de grafite.
Enfoque del paciente con cavitación pulmonar
Authors: Arango Rivas Ana María , Zuluaga Quintero Mónica
Published: October 2020

Una cavitación es un hallazgo común en imágenes pulmonares, secundaria a condiciones infecciosas, inflamatorias, tumorales y autoinmunes, siendo las primeras la causa más común en todos los niveles de atención y geográficos. El abordaje diagnóstico debe ser riguroso, integrando la imagen con la historia clínica del paciente, sus antecedentes personales y exposiciones, así como el tiempo de evolución de los síntomas; estos son elementos clave para el enfoque. Siempre es fundamental integrar los hallazgos clínicos con el laboratorio y la patología para llegar a un diagnóstico preciso y a un tratamiento oportuno, pues la imagen aislada no es suficiente, dadas las múltiples etiologías descritas y la variedad de presentación que hacen de este signo radiológico solo una premisa a la confirmación de una enfermedad subyacente.

Este trabalho apresenta o desenvolvimento de um inversor monofásico isolado conectado à rede empregando a topologia boost-full-bridge (BFB). Utiliza-se este conversor CC-CC em uma estrutura unfolding na qual se modula semiciclos positivos senoidais de corrente e um inversor operando em baixa frequência em sincronismo com a rede, fazendo a injeção da corrente senoidal. Esta topologia apresenta comutação suave em todos os interruptores, reduzindo as perdas. Também apresenta a operação intercalada no estágio de entrada, reduzindo os esforços de corrente e a ondulação de alta frequência na corrente de entrada. A estrutura proposta permite a utilização de modulações diferentes e simultâneas, aumentando o grau de liberdade no controle. Esta característica pode ser utilizada para controlar simultaneamente a corrente senoidal de saída, o barramento intermediário de tensão, a operação do MPPT e a redução ativa da ondulação de baixa frequência na entrada do inversor. Um protótipo de 200 W foi construído para validar a estrutura proposta, obtendo-se 3,8% de distorção harmônica total na corrente de saída, 91,6% de rendimento na potência nominal e um rendimento ponderado (CEC - California Energy Comission) de 92,3%.
