Novel application of a force sensor during sit‐to‐stands to measure dynamic cerebral autoregulation onset
Authors: Whitaker Alicen A. , Vidoni Eric D. , Aaron Stacey E. , Rouse Adam G. , Billinger Sandra A.
Published: April 2022

Current sit‐to‐stand methods measuring dynamic cerebral autoregulation (dCA) do not capture the precise onset of the time delay (TD) response. Reduced sit‐to‐stand reactions in older adults and individuals post‐stroke could inadvertently introduce variability, error, and imprecise timing. We applied a force sensor during a sit‐to‐stand task to more accurately determine how TD before the onset of dCA may be altered. Middle cerebral artery blood velocity (MCAv) and mean arterial pressure (MAP) were measured during two sit‐to‐stands separated by 15 min. Recordings started with participants sitting on a force‐sensitive resistor for 60 s, then asked to stand for 2 min. Upon standing, the force sensor voltage immediately dropped and marked the exact moment of arise‐and‐off (AO). Time from AO until an increase in cerebrovascular conductance (CVC = MCAv/MAP) was calculated as TD. We tested the sensor in four healthy young adults, two older adults, and two individuals post‐stroke. Healthy young adults stood quickly and the force sensor detected a small change in TD compared to classically estimated AO, from verbal command to stand. When compared to the estimated AO, older adults had a delayed measured AO and TD decreased up to ~53% while individuals post‐stroke had an early AO and TD increased up to ~14%. The stance time during the sit‐to‐stand has the potential to influence the TD before the onset of dCA metric. As observed in the older adults and participants with stroke, this response may drastically vary and influence TD.

Cinnamomum balansae Lecomte (Lauraceae), an economically important forest tree, is distributed in the tropical forests of central and northern Vietnam, which has been threatened in recent decades due to the destruction of its habitat and over-exploitation. The genetic diversity and population structure of the species have not been fully evaluated. We used a set of 15 microsatellites to analyze 161 adult trees from 9 different populations, representing the geographical distribution of C. balansae. Ninety-two different alleles were identified. Here our results showed a low genetic diversity level with an average H
o = 0.246 and H
e = 0.262, and a high level of genetic differentiation (F
ST = 0.601). The bottleneck tests indicated evidence of a reduction in the population size of the two populations (TC and CP). Additionally, all three clustering methods (Bayesian analysis, principal coordinate analysis, and Neighbor-joining tree) were identified in the two genetic groups. The Mantel test showed a significant positive correlation between genetic distance and geographic distance (R
2 = 0.7331). This study will provide a platform for the conservation of C. balansae both in ex-situ and in-situ plans.
Generate high data rate of optical carries by using nanomaterial graphene in slab waveguide
Authors: Alwan Saib Thiab , Mahmood Omar Abdulkareem , Mahmood Tahreer
Published: April 2022

Single mode is one of the most practical applications in microwave propagations because of its high mode resolution and low transmission loss. In this paper, the single mode graphene material was implemented in slab waveguide to study the performance and optical properties of graphene material; the parameters that affect these models were found to be the cut-off frequency, attenuation wavenumbers, modes numbers, skin depth, angles incident, and propagation wave numbers. The effectiveness of these factors was simulated and analyzed using MATLAB software program. In this paper, the carriers were generated using nano-graphene; the optical carrier source provided seven carriers with the frequency spacing of 4.9682 GHz. After splitting the carriers using optical demultiplexer, these carriers were modulated independently using optical Quadrature phase shift keying (QPSK) modulators at symbol rate equal to 4.9682 Gsymbol/s; this matches the frequency spacing of the carriers. Under this argument, the total data rate was equal to 2*7*4.9682 Gsymbol/s = 69.5548 Gbit/s, and the total bandwidth was 34.774 GHz. These carriers were found to work in optical communication with high data rate.

Authors: Kim Dong Jin
Published: April 2022

This study presents an overview of the literature of mindfulness in education, which is based on the definition of mindfulness, and accompanying key terms, and the philosophy and practices it involves. The review includes a survey of Buddhism, Eastern and Western mindfulness traditions. This literature review gathers the thinking of scholars on the importance of mindfulness and its beneficial practices—particularly in Western contexts—including mindfulness-based stress reduction (MBSR) and related therapies. The literature review is also a motivator in the use of mindfulness because it reveals its proven role in both helping career professionals and reducing stress for students by reducing the psychological and physical distress inherent in work and personal lives or students’ academic lives.
The linear sampling method for penetrable cylinder with inclusions for obliquely incident polarized electromagnetic waves
Authors: Deng Xia , Guo Jun , Li Jin , Yan Guozheng
Published: April 2022

Consider the scattering of electromagnetic waves by a penetrable homogeneous cylinder at oblique incident.
The Maxwell equations are then reduced to a system of a pair of the two-dimensional Helmholtz equations for 𝑧-components of the electric and magnetic field through coupled oblique boundary conditions.
This paper studies an inverse problem of recovering the penetrable obstacle from the far-field pattern of the electric field.
The well-known linear sampling method is used to solve this problem.
Compared with the usual inverse scattering problem, the coupled system and the oblique derivative boundary condition bring difficulties in theoretical analysis.
Some numerical examples are presented to illustrate the validity and feasibility of the proposed method.

Published: April 2022

Phase analytical studies in the Sc–Cu–In system led to samples of the solid solutions ScCu1–x–yIn1+xand ScCu2–xIn which were studied by X-ray powder diffraction. At room temperature the compounds ScCu1–x–yIn1+xcrystallize with the ZrNiAl type, space groupP6‾$\overline{6}$2m. Exemplarily, the structure of ScCu0.76In1.17was refined from single crystal X-ray diffractometer data, revealing strong anisotropic displacements for the scandium atoms and a mixed occupied Cu/In site. Superstructure formation is observed at low temperatures. The ScCu0.78In1.14and ScCu0.76In1.16structures were refined from diffraction data recorded at 90 K. Both compounds adopt the HfRhSn type, space groupP6‾$\overline{6}$2c, aklassengleichesubgroup of index 2; doubling of the subcellcaxis. The Cu/In filled trigonal Sc6prisms are strongly distorted in the superstructure, resulting from pairwise dislocation of the Cu/In atoms from ideal positions within an equidistant chain to shorter (311.0 pm) and longer (392.8 pm) Cu/In–Cu/In distances. Single crystal data of the Heusler phases ScCu1.95In and ScCu1.94In show small degrees of copper vacancies.

Published: April 2022

With the development of oil and gas exploration and development toward deep wells and ultra-deep wells, higher requirements are put forward for the working performance and service life of screw-drilling tools under the high-temperature environment. The failure of stator rubber bushing causes more than 30 % of screw-drilling tool failures. In this study, we mainly research the fatigue life prediction of rubber bushing under high temperature and high pressure and the influence of eccentricity and interference on fatigue life. Therefore, the uniaxial tensile test and fatigue test of hydrogenated nitrile butadiene rubber after 150°C /24 h ageing are carried out to obtain its mechanical properties and fatigue properties, and the fatigue life of rubber bushing is predicted by establishing the finite element mechanical model and combining it with the fatigue analysis software. The results show that the fatigue failure position of stator bushing is consistent with the theoretical and practical failure position and the error between the predicted fatigue life and the actual fatigue life is about 18.25 %. On this basis, the influence of eccentricity and interference on stator bushing fatigue life is analyzed. Fatigue life of stator bushing decreases with the increase of eccentricity or interference, which is consistent with the fatigue life curve of rubber material. The research results can provide reference for stator engineering application and bushing structure optimization of screw-drilling tools.
Characteristics and Prediction of Fatigue Resistance between Asphalt Pavement Layers Based on Shear Stiffness Decay Rate
Authors: Huang Yangquan , Luo Ting , Shang Jing , Rahman Ali , Ai Changfa
Published: April 2022

The evaluation of fatigue performance between asphalt pavement layers highly depends on fatigue life and shear stiffness. However, fatigue life and shear stiffness are comprehensive evaluation indexes. In the study of the formation mechanism and decay process of fatigue resistance, both of them cannot provide effective theoretical support. In this study, the shear stiffness decay curve was obtained through a four-point shear fatigue test under different loading conditions. The initial shear stiffness and the shear stiffness decay rate of interlayers were chosen to evaluate the initial resistance and process resistance. The effects of temperature, loading frequency, compressive stress, and shear stress on the evolution of interlayer fatigue performance were investigated. The findings of this study revealed that first, with the increase of the compressive stress perpendicular to the interlayer interface, the interlayer shear stiffness decay curve transitions from a cubic curve type to a quadratic curve type and gradually changes to a linear equation. Second, the ranking of influence degree of four factors on initial resistance and process resistance was obtained, and the influence mechanism analysis was carried out based on the variance analysis result. Finally, a multiple nonlinear regression model was established successfully to predict the fatigue life and to explain the internal connection between the initial shear stiffness, shear stiffness decay rate, and fatigue life.
The Concept of Intellectual Property Cases. Selected Issues
Authors: Niewęgłowski Adrian
Published: April 2022

This article relates to the concept of intellectual property cases, which has recently been added to the Polish Code of Civil Procedure (CCP). The introduction of this concept has to do with changes in the CCP, which have been in force in Poland since 1 July 2020. From that date, intellectual property cases are dealt with by the courts under a new special procedure. Classification of a particular case as an intellectual property case has important practical consequences: an intellectual property case is heard in distinct proceedings; otherwise, general regulations will apply. The definition of intellectual property cases which is in the CCP is not obvious and raises doubts. The aim of the article is to analyse this definition and to propose certain directions of interpretation.

This study aimed to measure and validate altitudes from existing sources with direct GNSS measurements and airborne lidar data. For this purpose, 12 mountain peaks located in the south part of Polish territory were selected. Measurements were performed using a GNSS receiver using the Real-Time Kinematic (RTK) or static techniques enabling altitude measurements with accuracy of 10 cm. GNSS was treated as the primary data source, as the direct field measurements can determine the highest point on each peak. The obtained results were confronted with historical, internet sources, and official altitude data. Moreover, each altitude was determined using lidar data from an airborne lidar dataset of Poland from the ISOK program and provided by the national agency. Significant discrepancies in data were already detected during the analysis of internet materials and traditional maps, up to a few meters. The differences between measured and internet sources in altitude of mountain peak range from 27 cm to 504 cm. This study has shown the need to re-measure the altitudes of the mountain peaks and determine the highest point correctly.
Synthesis of the S/AgBr nano/micropowder in DMSO-water system
Authors: Khan Natalya
Published: April 2022

A new synthesis method of S/AgBr nano/micropowder based on sulfur and silver halide was developed. The nano/micropowder was obtained in the DMSO-water system, in two stages. Initially, sulfur was dissolved in DMSO at 120°C. The resulting solution was cooled to room temperature and separated from sulfur by filtration. Then, pre-prepared water solutions of AgNO3 and NaBr were introduced drop by drop into a sulfur solution in DMSO, at room temperature. The phase composition and structure of the precipitated powdery sediment were studied by X-ray diffraction analysis (XRD) and Raman spectroscopy. Scanning electron microscopy (SEM) was used to study the morphology and particle size. XRD showed the presence of the crystalline phase of AgBr, while the Raman spectra were characterized by the presence of sulfur and AgBr peaks. The SEM results showed that the S/AgBr is represented by oval, spherical and triangular particles of a homogeneous structure; the particle size was in the range from 300 to 800 nm.

Published: April 2022

A study was conducted to quantify tar formation in a stratified downdraft gasifier using wood pellets. The effect of biomass flow rate on tar concentration was also analyzed, and more than thirty compounds in tar were quantified. Among the different compounds in tar, tertiary condensed products such as toluene, o/p-xylene, naphthalene, phenol, styrene, and indene were observed in significant amounts. Tar concentration in the syngas was found to be in the range of 340 to 680 mg/Nm3. These concentrations were found to be much higher when compared to a similar gasifier using woodchips.
Hygienic behavior and fat body development in worker bees (Apis mellifera L.)
Authors: Lazarov S. , Zhelyazkova I.
Published: April 2022

Abstract. Testing for the level of manifestation of the hygienic behavior of 32 bee colonies from the local honey bee (Apis mellifera L.) from three apiaries has been carried out. Depending on the level of manifestation of the cleansing instinct, two groups of bee colonies have been formed – hygienic (these clean over 95% of the cells with dead brood up to the 48th hour after killing the brood) and non-hygienic (these clean less than 95% of the cells with dead brood up to the 48th hour). Worker bee samples have been taken from the tested bee colonies to determine the level of fat body development. The fat body is important for the bee organism, since in addition to being a fat and carbohydrate storage depot, it is also considered to be the center of metabolism in insects. The analysis of the results from the present study revealed that the mean value of the level of fat body development in worker bees from the group of hygienic bee colonies was 2.76±0.038. In the group of non-hygienic colonies this value was 7.61% lower (2.55±0.079). This difference is statistically significant at p≤0.05. Significant differences have been found in the development of the fat body in worker bees from apiaries at a distance of 100 km without regard to hygienic behavior and according to hygienic behavior. The results obtained suggest that there is a correlation between the level of fat body development and the hygienic behavior in bees.
Loot box purchasing is linked to problem gambling in adolescents when controlling for monetary gambling participation

Published: April 2022

Background and aims

Purchasing loot boxes in digital games is akin to gambling as it involves risking money for a chance-based reward of uncertain value. Research has linked buying loot boxes to problem gambling amongst adolescents, but has not examined co-occurring gambling participation. This study examined links between loot box purchasing and problem gambling amongst adolescents while controlling for monetary gambling participation.

Methods

Two survey samples of Australians aged 12–17 years were recruited through advertisements (n = 843) and online panels (n = 826). They included n = 421 and n = 128 adolescents, respectively, who met criteria for problem gambling.

Results

Past-month loot box purchasing was significantly related to gambling problems in bivariate analyses. When including age, gender and past-month monetary gambling, loot box purchases were still associated with at-risk and problem gambling in both samples. As expected, these other predictors attenuated the predictive value of recent loot box purchases in relation to gambling problems. The odds-ratios, nevertheless, were still in the predicted direction and remained significant. When controlling for monetary gambling, age and gender, recent loot box purchasing increased the odds of problem gambling 3.7 to 6.0 times, and at-risk gambling 2.8 to 4.3 times.

Discussion and conclusions

While causal relationships between loot box purchasing and problem gambling remain unclear, the results indicate that loot boxes disproportionately attract adolescents experiencing gambling problems, adding to the financial stress already caused by gambling. Consumer protection measures, youth and parental education, and age restrictions on loot box games are needed to protect young people.

Jacques Maritain's book Antimoderne and its representations of modern thought (1922)
Authors: Souza Rodrigo Augusto de
Published: April 2022

Resumo Este artigo procura apresentar as representações sobre o pensamento moderno, elaboradas por Jacques Maritain (1882-1973) e publicadas na sua obra Antimoderne, de 1922. Considera-se que essa obra assinala uma mudança no pensamento de Maritain, isto é, a sua adesão ao neotomismo e o seu engajamento entre os intelectuais católicos na França. A compreensão da apropriação e da interpretação do neotomismo por Maritain constitui um elemento fundamental no entendimento de sua crítica ao pensamento moderno. Com base na história intelectual e em diálogo com algumas contribuições da história cultural, busca-se realizar a conexão entre vida e obra na trajetória de Maritain. Desse modo, a obra em questão situa-se como um fator explicativo de um período da trajetória de vida do intelectual.
Os livros de filosofia do PNLD/2018 e a lei 10.639/03: reflexões sobre a diversidade étnico-racial no material didático de filosofia no Ensino Médio
Authors: Ferreira Soraia Aparecida Belton , Ferreira Amauri Carlos
Published: April 2022

Resumo A construção dessa pesquisa parte da concepção decolonialista e discorre sobre a filosofia, seu ensino e a diversidade étnico-racial sob a perspectiva da Lei 10.639/03. A pesquisa é qualitativa e os resultados dados foram obtidos através da coleta documental, que teve como objeto de análise os oito livros de filosofia do PNLD/2018 e um questionário misto aplicado a 31 professores de filosofia do Ensino Médio (EM). A pesquisa apontou que nos livros analisados e nas aulas de filosofia no EM, não há a efetiva inclusão da Lei 10.639/03 em seus conteúdos. Sendo assim, é possível afirmar que a filosofia ainda tem muito a fazer em relação à temática da diversidade étnico-racial, devendo problematizar seu próprio eixo epistemológico e abrir espaço para que o fazer filosófico seja fator crucial na transformação das teorias e práticas racistas presentes dentro e fora dos muros escolares fomentando a problematização das relações sociais vigentes, de modo a promover as lutas antirracistas.

Authors: Sun Yang , Gu Zhenxue , Xu Zhenyang , Wang Chongxiao , Song Dewei
Published: April 2022

A 1257 m long special-shaped deep excavation was performed in the city centre of Nanjing, China. Full-width and half-width top-down construction methods were adopted. Based on long-term monitoring data from the project, the evolution characteristics of the diaphragm wall (DW) deformation, the ground settlement and the settlement of adjacent buildings were analysed. The interrelationships among these parameters and their relationships with the excavation process, structural system and geological conditions were also studied. The results showed that the horizontal displacement of the DWs was less than 1% of the excavation depth and the position of the maximum horizontal displacement was generally located from 4 m above the excavation surface to the vicinity of the excavation surface. The influence range of the excavation on the surrounding ground settlement was mostly within three times the excavation depth. The ground settlement varied from 0.1–0.5% of the excavation depth to 0.3–5.0 times the maximum horizontal displacement of the DW. During the construction process, the settlement rate suddenly increased only when the excavation reached the soft soil layer. Building settlement was found to be related to the excavation deformation, structure forms, foundation types and distance to the foundation pit.

Published: April 2022

Background: With increasing use, the incidence of adverse events associated with sugammadex, a neuromuscular blockade reverser, is increasing. This study aimed to identify and analyze cases of adverse events caused by sugammadex reported in Korean population.Methods: Out of a total of 12 cases detected using various keywords in the Korean Journal of Anesthesia, Anesthesia and Pain Medicine (Seoul), KoreaMed, PubMed, EMBASE, Web of Science, and The Cochrane Library-CENTRAL from 2013 to December 2020, 10 cases directly associated with sugammadex were selected.Results: Adverse events included five cases of anaphylaxis, one case of cardiac arrest, one case of profound bradycardia, one case of negative pressure pulmonary edema, and two cases of incomplete recovery. Three patients had American Society of Anesthesiologists physical status ≥ 3, two had emergency surgery, and two had a history of allergic reaction. Neuromuscular monitoring was applied in nine cases. The average dose of sugammadex was 2.87 mg/kg, and there were six cases in which one full vial was used, regardless of the state of neuromuscular recovery. Sugammadex was administered immediately after surgery in two cases, at train of four (TOF) 0 in four cases, at TOF 3 in one case, and after evaluation of the clinical signs only with no neuromuscular monitoring in one case.Conclusions: Even with neuromuscular monitoring, an excessive dose of sugammadex was observed. Given that adverse events tend to occur within 10 min of administration, continuous monitoring is important even after administration.
Association of Vitamins D, B9 and B12 with Obesity-Related Diseases and Oral Microbiota Composition in Obese Women in Croatia

Published: April 2022

Research background. Oral microbiota has become an important factor in obesity, but its association with obesity-related diseases and serum 25-hydroxy vitamin D [25(OH)D] and B complex amounts is still uncertain. The main aim of the paper is to determine the variation in oral microbiota composition as a response to the vitamin status and obesity-related diseases in obese females from Croatia. We hypothesized that the prevalence of probiotic or pathogenic bacteria in the oral cavity of obese women in Croatia depends on the amounts of vitamin B9 (folic acid), B12 and 25(OH)D in serum and/or hypertension, diabetes and prediabetes diagnosis.
Experimental approach. To test the defined research hypothesis, female individuals with body mass index (BMI)≥30 kg/m2 (N=70) were recruited to participate in this study. Obese women were divided into groups according to BMI value, diagnosis of obesity-related diseases and amount of micronutrient in blood. For the quantitative determination of folic acid, vitamin B12 and 25(OH)D in serum, an electrochemiluminescence protein binding assay (ECLIA) was performed. Microorganisms isolated from the saliva of obese women were analyzed by MALDI-TOF mass spectrometer.
Results and conclusions. The presented results do not support the hypothesis that the prevalence of probiotic or pathogenic bacteria in the oral cavity of obese women in Croatia depends on the amount of micronutrients. On the other hand, hypertension and diabetes/prediabetes favour the growth of oral pathogens, specifically increased levels of Candida sp.
Novelty and scientific contribution. To the best of our knowledge, this is the first study showing the relationship between obesity, micronutrient amount, oral microbiota composition, and the incidence of obesity-related disease. We included only obese women from Croatia, so it is regionally specific. Also, we have shown that oral microbiota composition is not connected with micronutrient deficiencies but only with obesity-related diseases.

Authors: Steinmann Victor W. , Stevens Warren D.
Published: April 2022

Background: Polystemma (Apocynaceae subfamily Asclepiadoideae) is a small genus currently with seven species characterized by having white glandular trichomes becoming crystalline in age; filiform corona appendages; and fusiform, smooth, mottled follicles. Exploration in the Balsas Depression of Michoacán, Mexico resulted in the discovery of an unknown species of Polystemma .
Questions: Are the unknown Polystemma plants occurring in the Balsas Depression of Michoacán new to science? If so, how are they distinguished from other species of the genus, what are their ecological preferences, what is their distribution, and are they endangered?
Studied species: Species of Polystemma .
Study site and dates: Balsas Depression, Michoacán, México; 2001, 2003, 2004, 2014.
Methods: Fieldwork to collect herbarium specimens and photograph plants; review of literature on Polystemma to determine taxonomic status; preparation of a morphological description; evaluation of conservation status using IUCN Redlist criteria.
Results: Polystemma fishbeiniana is proposed as a new species and illustrated with photographs.  It occurs at two locations in the xeric scrub and open thorn forest of the Zicuirán-Infiernillo Biosphere Reserve, at elevations from 275 to 400 m.  Flowering occurs from June to September, with mature fruits present from October to March; dehisced fruits can persist on the plants for almost a year. Its conservation status is assessed as Endangered, EN B1ab(iii)+2ab(iii).
Conclusions: Polystemma fishbeiniana is distinguished from congeners by its suffrutescent habit, small leaves, and flowers abaxially yellowish with a blackish to dark burgundy red margin and central line with short lateral extensions.These traits are otherwise unknown in the genus.

Gender Wage Gaps by Knowledge Intensity in Turkish Service Sector
Authors: SEFİL TANSEVER Sinem
Published: April 2022

This study aims to determine whether knowledge intensive services (KIS) reduce gender wage gaps and women’s labor attributes in the Turkish service sector by employing survey data from the Turkish Household Labor Force Survey of 2019. Both mean wage differences and wage differences across the wage distribution are examined by employing the Oaxaca–Blinder wage decomposition, along with the Heckman sample selection procedure, and the Melly decomposition approaches respectively. The results suggest that, in spite of the relatively higher mean wages of women in KIS employment, KIS offers worse employment outcomes for women in terms of intra-sector wage inequality, and relatively poorer working conditions than the Turkish service sector.
Is Popularity of Technical Analysis a Product of Low Financial Literacy and Overconfidence Among Stock Market Investors?
Authors: UNAL Serkan
Published: April 2022

Individual investors’ overall return in stock markets decreases with the increase in trade frequency due to factors such as commission expenses, insider trading, spreads, and institutional investors’ high-frequency algorithms. In this study, the relationship between believing the technical analysis method and the financial literacy level, overconfidence, and high return expectations of investors have been analyzed with the use of survey data of 3,844 people. Although the efficiency of technical analysis and success in high-frequency trading depends on investor’s analytical skills, it is found that technical analysis and trading are very popular among people who have low financial literacy and irrational high return expectations.
Reaction of Monetary policy to Cost-Push Inflation in Turkey: A Leaning against Wind?
Authors: TETİK Metin , BARİ Bilgin
Published: April 2022

In Turkey, monetary policy responds to cost shocks rather than the inflation gap and output gap. To clarify this policy, we estimate the linear and non-linear Taylor rule using the Thresold GMM for 2006:01-2020:07. The linear model estimates that the policy rate responds significantly to the inflation gap and the real effective exchange rate. The non-linear model captures that monetary policy differs in regimes where imported goods and input prices are set as high and low. In a high price regime, monetary policy also reacts to cost-push shocks. The response of monetary policy to the exchange rate implicitly leads to "a leaning against the wind".
Hepatoprotective effect of a mixture of medicinal plants and vitamins in Rattus norvegicus with liver poisoning
Authors: Cueva-Mestanza Ruben Eduardo
Published: April 2022

In the present investigation, the hepatoprotective effect of a powder mixture of leaves of Gentianella alborosea(Gilg) Fabris, Cynara scolymus, Berberis vulgaris, Peumus boldus, Taraxacum officinaleroots, and vitamins B6 and B12 (PROTHEPA®) was studied in Rattus norvegicus. Sprague Dawley with paracetamol-induced liver intoxication. In the experiment, 25 female rats were randomly distributed into five groups, G1: physiological serum (SF) 4mL/kg; G2 (negative control): SF 4mL/kg + paracetamol 400mg/kg; G3 (positive control): Silymarin 100 mg/kg + paracetamol 400 mg/kg; G4: PROTHEPA® mixture 100 mg/kg + paracetamol 400 mg/kg; and G5: PROTHEPA® mixture 500 mg/Kg + paracetamol 400 mg/kg. Biochemical analyzes were performed to determine the liver profile (glutamic oxalacetic transaminase (GOT), glutamic pyruvic transaminase (GTP), total bilirubin (BT), and total protein (PT)), as well as pathological evaluations. The results showed that G2 presents a significant increase in TGP (80.20 ±1.3), BT (0.39 ±0.23), anda significant reduction in PT (4.82 ±0.46). As for G3, G4 and G5; all tests remained within normal values, similar to G1. These results demonstrate that the PROTHEPA® mixtures of 100mg/kg and 500mg/kg have a hepatoprotective effect, which is corroborated by the anatomo-pathological evaluations.
Soil attributes and crops productivity: changes due to the long time use of animal manure
Authors: Loss Arcângelo , Souza Monique , Rogério Lourenzi Cledimar , Brunetto Gustavo , Lovato Paulo Emilio , Comin Jucinei José
Published: April 2022

Animal manure may be used as a nutrient source for annual and perennial crops and pastures, promoting nutrient cycling and reducing costs with mineral fertilizers acquisition. Additionally, they are expected over the years to modify soil chemical, physical, and biological attributes. This review addresses the effect of animal manure applications on the soil-plant interface, emphasizing the following aspects: (a) animal manure characteristics that affect soil attributes, (b) changes in chemical, physical, and biological attributes of soils with a history of animal manure applications, and (c) effect of animal manure application on crop biomass production and yield. Changes on soil attributes depends on the animal manure and pedoclimatic characteristics. Animal manure applications in soil associated with mineral manure increase soil organic carbon and crop yield. Aggregates, density and water infiltration are favored by applying animal manure with high C:N. Macrofauna, microbial and biological activity increase with animal manure application. Finally, yield increases do not always accompany the improvement of all soil attributes. The effects of animal manure application on soil quality are more pronounced when carried out in an integrated manner with other soil management and conservation strategies.
The propagation of forage kochia cutting in different IBA concentrations and at holding times
Authors: KOÇ KOYUN Nur , ACAR Ramazan
Published: April 2022

Forage kochia, a subshrub forage plant, grows naturally in the pastures of dry areas in Turkey. Their seeds grow slowly in nature, and being short duration of seed viability could be caused by limitations on the cultivation of forage kochia in Turkey. Forage kochia seedlings can be produced serially quickly with cutting propagation as vegetation propagation method. Therefore, forage kochia cuttings were exposed to 12 different IBA concentrations (250, 500, 1000, 1500, 2000, 2500, 3000, 4000, 5000, 6000, 10000, and 15000 mg kg-1) at four holding times (5, 30, 180, and 900 s) in this research carried out Completely Randomized Design in the greenhouse. We investigated the percentage of rooting, the number of the root, shoot and root length, shoot and root weight, dry root weight, and leave yellowing of these cutting. The best developments in the percentage of rooting (100%), number of roots (> 7), shoot length (> 20 cm), root length (>10 cm), root weight (>0.60 g), dry root weight (>0.1 g) and leave yellowing (score >1.60) were obtained from 500 mg kg-1 IBA at 900 s, 5000 mg kg-1 IBA at 180 s, and 10000 mg kg-1 IBA at 5 s interactions. As a result, we advised 500 mg kg-1 IBA at 900 s, 5000 mg kg-1 IBA at 180 s and 10000 mg kg-1 IBA at 5 s for the quick and economically cutting propagation of forage kochia.
How Did the Post-9/11 GI Bill Affect Veteran Students’ Undergraduate College Choices? An Application of Propensity Scores in Difference-in-Differences Models
Authors: ZHANG LIANG
Published: April 2022

The Post-9/11 GI Bill represents significant public investment in and commitment to veterans who have served in the armed forces and those who will serve in the future. Recent studies have examined its effect on veterans’ college participation. In this study, Liang Zhang uses data from four waves of the National Postsecondary Student Aid Study between 2004 and 2016 to examine the effect of the Post-9/11 GI Bill on veterans’ college choices. This analysis finds, most notably, that veterans who received federal education benefits attended colleges in more expensive locations after the implementation of the bill. Moreover, a greater proportion of veterans attended private for-profit institutions instead of public institutions. Also, the bill had no significant impact on choices in terms of institution level as measured by four-year versus two-year colleges, Carnegie Classification, or program type (online versus in-person).
