Authors: Selangga Dewa Gede Wiryangga , Wiyono Suryo , Susila Anas Dinurrohman , Hidayat Sri Hendrastuti
Published: March 2022

Yellow leaf curl disease in chili pepper has been reported in Bali Island since the early 2012. Research was conducted to identify the virus causing this disease and disease distribution in Bali. Field survey was carried out to observe disease intensity and to collect field samples from several chili pepper growing areas in Bali (Karangasem, Bangli, Tabanan, and Gianyar). Begomovirus identification from field samples was then conducted by polymerase chain reaction method using universal primers SPG1/SPG2, followed by an analysis of the amplified target DNA sequences. The incidence of pepper yellow leaf curl disease reached 100% at all sites and disease severity reached 18%−87%. Begomovirus specific DNA fragment measuring 912 bp was successfully amplified from 12 field samples. Sequence analysis of DNA fragments showed the highest homology with Pepper yellow leaf curl Indonesia virus (PYLCIV). Further phylogenetic analysis confirmed the relationship between PYLCIV isolates from Bali and various PYLCIV isolates from Indonesia.
Fiscal Rules in Economic Crisis: The Trade-off Between Consolidation and Recovery, from a European Perspective
Authors: Díaz-Roldán Carmen , Filho Fernando Ferrari , da Silva Bichara Julimar
Published: March 2022

In this study, we will perform a simulation exercise to investigate whether the use of explicit fiscal rules improves the macroeconomic performance in the economic framework of the European Union (EU), where the fall in income levels occurred very asymmetrically, and this has accentuated the social inequality that existed before the recent crises. To evaluate the performance of fiscal rules, we will allow for a fiscal rule keeping the growth of the public expenditure below the growth of the inflation. This special design of the fiscal rule is a novelty in the European context, although the inflation constraint has been successfully implemented in other countries as, for example, Brazil. As the results, we expect to find that before the financial crisis of 2008, the EU public finances keep relatively stable. However, after the crisis, the budget of the member states suffered a significant deterioration. In addition, therefore, we will discuss to which extent the use of proper fiscal rules could help to rationalize fiscal consolidation efforts.

Biochemical and histopathological evaluation of liver, kidney, and pancreas in normal Sprague Dawley rats administered aqueous extract of beetroot (Beta vulgaris)
Authors: Olumese Fidelis E. , Oboh Henrietta A.
Published: March 2022

Objectives

The safety and potentials of beetroot juice as a nutraceutical was assessed.

Methods

Beetroot obtained was identified by a taxonomist and washed thoroughly, chopped finely into small bits, and blended. The aqueous juice obtained was freeze dried. Six groups of five animals were distributed according to sex and body weight (average 135–185.0 g). The aqueous extract of beetroot was dissolved in distilled water and administered in a range of 200–3,000 mg/kg body weight/day/for 28 days using gastric gavage. Weight of animals, and feed consumption were determined weekly. On the 28th day the animals were fasted for 12 h and euthanized. Blood was collected for biochemical assays, while the kidney, liver, and pancreas were weighed and kept in buffered formalin for histopathological evaluation.

Results

Serum ALT was unaltered in all the groups, while the level of AST was significantly (p<0.05) reduced at 500, 2,000, and 3,000 mg/kg. ALP was significantly reduced at 200 mg and 1,000 mg when compared to control. Total protein decreased significantly at 200 mg when compared to control and 2,000, 3,000 mg respectively. There were no significant changes in K+ and Cl− in all the groups. Urea at 200 and 3000 mg were significantly reduced and increased respectively. Creatinine concentration was not altered. Histopathological examination, did not reveal any unusual findings in the organs examined.

Conclusions

This study revealed that beetroot juice may not be toxic to the organs evaluated in the tested doses, therefore the extract can be said to be safe for the duration of study in an animal model.

Authors: Rall Klaus , Findeklee Joachim
Published: March 2022

Neben der beim HSC-Fräsen selbstverständlich hohen Oberflächengüte ist für viele Anwendungen auch eine hohe Fertigungsgenauigkeit erforderlich. Die erreichbare Fertigungsgenauigkeit beim HSC-Fräsen wird maßgeblich durch axiale Spindelverlagerungen beeinflußt, die bei den eingesetzten Hochfrequenzspindeln konstruktionsbedingt auftreten und daher unvermeidbar sind. Deshalb wurde am Arbeitsbereich Werkzeugmaschinen und Automatisierungstechnik der TU Hamburg-Harburg ein Verfahren zur Kompensation dieser Verlagerungen entwickelt.

Sorensen, AM, Chavda, S, Comfort, P, Lake, J, and Turner, AN. Intra- and interday reliability of weightlifting variables and correlation to performance during cleans. J Strength Cond Res 36(11): 3008–3014, 2022—The purpose of this investigation was to examine intra- and interday reliability of kinetic and kinematic variables assessed during the clean, assess their relationship to clean performance, and determine their suitability in weightlifting performance analysis. Eight competitive weightlifters performed 3 sets of single repetition cleans with 90% of their 1-repetition maximum (1RM). Force-time data were collected via dual force plates with displacement-time data collected via 3-dimensional motion capture, on 3 separate occasions under the same testing conditions. Seventy kinetic and kinematic variables were analyzed for intra- and interday reliability using intraclass correlation coefficients (ICCs) and the coefficient of variation (CV). Pearson's correlation coefficients were calculated to determine relationships between barbell and body kinematics and ground reaction forces, and for correlations to be deemed as statistically significant, an alpha-level of p ≤ 0.005 was set. Eleven variables were found to have “good” to “excellent” intra- and interday ICC (0.779–0.994 and 0.974–0.996, respectively) and CV (0.64–6.89% and 1.14–6.37%, respectively), with strong correlations (r = 0.880–0.988) to cleans performed at 90% 1RM. Average resultant force of the weighting 1 (W1) phase demonstrated the best intra- and interday reliability (ICC = 0.994 and 0.996, respectively) and very strong correlation (r = 0.981) to clean performance. Average bar power from point of lift off to peak bar height exhibited the highest correlation (r = 0.988) to clean performance. Additional reliable variables with strong correlations to clean performance were found, many of these occurred during or included the W1 phase, which suggests that coaches should pay particular attention to the performance of the W1 phase.

Published: March 2022

The properties of storage system structures were largely determined by the particle size and compressive modulus of the granular material inside, which is an important issue for silo structure design. The large compressibility and complex contact relationship of granular materials in the cell are needed for the reliable pressure measurement. A set of testing system and experiment method were designed to reveal the size effect of earth pressure cells in the loading and unloading process of granular materials. Different compressive moduli were adopted for the selection of the appropriate granular particle size. Four types of granular materials including fine sand, coarse sand, rapeseed, and wheat were used as raw materials. Three types of earth pressure cells were used in this study with different sizes, and a series of loading and unloading tests were conducted with liquid. The interaction between the cell and granular material and its main factors were discussed. The results show that the pressure exhibits a linear relationship with the strain in the loading and unloading process in liquid surroundings. Owing to the interaction between the cell and granular materials, the pressure increased linearly with the strain in the loading process as well as a nonlinear relationship were exhibited in the unloading process. In the unloading process, an exponential model was proposed to simulate the pressure and strain based on the significant hysteresis phenomenon observed during unloading process. The hysteresis ratio (R) index was adopted to evaluate the hysteresis. It was found that the material type of surroundings and particle size were believed to be the two major factors affecting the R value. To improve the accuracy of granular material interface pressure measurement, the earth pressure cell with a d/d0 ratio exceeding 11 was recommended. The results obtained in this study provide theoretical foundation for energy saving and safety granary structure design.

Recombinase Polymerase Amplification for Rapid Detection of Zoonotic Pathogens: An Overview
Authors: Lv Ruichen , Lu Nianhong , Wang Junhu , Li Yuexi , Qi Yong
Published: March 2022

With the advent of molecular technology, several isothermal techniques for rapid detection of zoonotic pathogens have been developed. Among them, recombinase polymerase amplification (RPA) is becoming an important technology for rapid, sensitive, and economical detection of zoonotic pathogens. RPA technology has the advantage of being able to be implemented in field settings, because the method requires minimal sample preparation and is performed at a constant low temperature (37–42°C). RPA is rapidly becoming a promising tool for the rapid detection, prevention, and control of zoonotic diseases. This article discusses the principles of RPA technology and its derivatives, including RPA coupled with lateral flow testing (RPA-LF), real-time fluorescence RPA, electrochemical RPA, and flocculation RPA, and their applications in the detection of zoonotic pathogens.
COLOR PERCEPTION ESTIMATIONS OF METAMERIC PAIRS UNDER DIFFERENT ILLUMINANCE LEVELS
Authors: Mukthy Azmary Akter , Vik Michal , Viková Martina
Published: March 2022

LEDs or light emitting diodes of the lighting class dominate both the indoor and outdoor lighting industries today due to their accuracy and consumer-friendly color temperature. In the context of color science, it is necessary to analyze both the spectral power distribution of lighting and the human characteristics of color perception under these lights. In this article, we provide estimates of the appearance of eleven metameric pairs under LEDs with four correlated color temperatures and six illuminance levels, using color difference formulas based on the CIELAB, CAM02-UCS, and CAM16-UCS models to verify our estimates. We followed ASTM D4086 standard visual methods for detecting metamerism and for estimating the magnitude of a metameric color difference. Our investigations found that color appearance models are more reliable than CIELAB in evaluating color difference under various LED conditions. CAM16-UCS more accurately predicted the color difference estimates between all three formulas. Our comparative study confirms that the variation in the estimates with the CCT and illuminance levels of the LED sources depends on the color appearance model used. The results also showed that in order to determine the color difference of metameric pairs, optimal conditions regarding the colorimetric properties of the samples and the variability of the observer should be considered separately. We noticed an increasing correlation trend with increasing illuminance. However, there was no such increase or decrease trend in CCTs. The trend of the STRESS change in the color appearance models showed the influence of the chromatic adaptation, but the establishment of adaptation patterns is far beyond the scope of this work. Although our research has had limitations on correlated color temperature and illuminance, we believe that it can be beneficial for the lighting application to ensure correct lighting decisions when assessing the color differences of metameric pairs.
History as a Tool for Natural Science
Authors: Ten Hagen Sjang L.
Published: March 2022

Historical methods have long been put to use in the making of natural knowledge. In this article, I examine the use of historical methods by nineteenth-century physicists, focusing on the Austrian researcher Ernst Mach in particular. I argue that Mach applied methods characteristic of the then-dominant historical and philological disciplines to his own discipline of physics. He construed history as a tool for the physicist. On the basis of a study of his notebooks and correspondence with the chemist-turned-historian Emil    Wohlwill, I explain what he sought to achieve by means of this tool, and reconstruct the practices characterizing his historical research. These practices included the reading, ordering, and comparison of textual sources. Moreover, Mach appropriated the historical-philological method of source criticism. I show that prominent fellow physicists of Mach, including Johann Poggendorff and Hermann von Helmholtz, made use of similar historical methods, even though their aims were different. Together, the cases of these history-writing physicists illustrate how history and natural science continued to intertwine in a time of increasing disciplinary fragmentation.

Pritom se misli na iskorištavanje geoprometnoga položaja rijeka na vlastelinstvima, izgradnji skela, mlinova, sustava brana i ribnjaka te kupališta. Rad osim toga propituje u kolikoj je mjeri Kaptol uspijevao upravljati posjedima koji su poplavljivani bilo prirodnim bilo ljudskim djelovanjem. Teza od koje se polazi jest da su Kaptol i njegov okoliš bili u stalnome međudjelovanju. To znači da je to, i u onim prilikama kada je Kaptol maksimalno iskorištavao vodene resurse, uzrokovalo promjene u okolini i ponovnu prilagodbu.

Objective

Central sensitivity of thyroid hormone refers to the sensitivity of hypothalamic–pituitary–thyroid (HPT) axis to the change in circulating free thyroxine (fT4). A complex relationship exists between thyroxine levels and iodine nutritional status. To explore the relationship between thyroid hormone sensitivity and iodine nutritional status in elevated thyrotropin (TSH), we used national data to assess the relationship between thyroid hormone sensitivity and iodine nutritional status with contrasting demographic characteristics in China.

Methods

We enrolled 12,197 participants with TSH > 4.2 mIU/L from China. Serum and urine samples were collected, and we measured serum fT4, TSH, thyroid peroxidase antibody (TPOAb), and thyroglobulin antibody (TgAb) levels and urinary iodine concentration (UIC). The thyroid hormone sensitivity indices were calculated based on fT4 and TSH. The thyroid feedback quantile-based index (TFQI) is a new index to reflect thyroid hormone sensitivity. Higher TFQI quartiles indicated lower thyroid hormone sensitivity.

Results

The odds ratios (ORs) for the fourth versus first TFQI quartile were 0.84 (95% CI 0.72–0.99) for iodine deficiency, 1.24 (95% CI 1.05–1.47) for TPOAb+, and 0.44 (95% CI 0.40–0.50) for females. The OR of the fourth and first TFQI quartiles for age <30 years and >60 years was 2.09 (95% CI 1.82–2.41) and 1.19 (95% CI 1.05–1.36), respectively (P  < 0.05). Other thyroid sensitivity indices also yielded similar results.

Conclusion

Thyroid hormone sensitivity and age have a U-shaped association in individuals with elevated TSH. Increased thyroid hormone sensitivity is associated with iodine deficiency and the female gender. Decreased thyroid hormone sensitivity is associated with TPOAb+. These findings are interesting and potentially useful for understanding the interaction between iodine nutrition and the hypothalamic–pituitary–thyroid axis.
A influencia da música de Juan Montes nas composicións do violinista Manuel Quiroga Losada
Authors: Vicente Ilduara
Published: March 2022

Manuel Quiroga supuxo unha figura fundamental dentro da historia da música galega. Como intérprete acadou o maior dos logros e como ‘home do Renacemento’, cultivou a arte da composición e da pintura. Nun contexto ligado ao nacionalismo musical e pola súa relación co panorama intelectual galego, Manuel Quiroga escribíu algunhas obras adicadas a Galicia. Malia seren estas pouco abondosas, resultan moi interesantes pola inclusión de temas tradicionais nas mesmas, ben como de obras de autores do Rexurdimento musical. Aquí analízanse dúas das súas composicións máis icónicas, plantexando a afinidade de Quiroga pola música do Rexurdimento e especialmente por Juan Montes, a súa relación co folclore, todas as posibles fontes de inspiración e o tratamento de dita música nun xénero de corte clásico e virtuosístico.
Políticas Editoriales y Peregrinaciones. Una aproximación a los Catálogos de empresas editoriales en Argentina (Siglos XX y XXI)
Authors: Román Viviana
Published: March 2022

La industria editorial en Argentina tuvo sus orígenes a fines del siglo XIX. En el siglo XX se consolidó y tuvo su momento de esplendor hacia mediados de ese siglo. Siguió luego un camino en consonancia con la concentración y extranjerización del sector editorial mundial acontecida con fuerza desde fines del siglo XX. En contrapartida se asistió a la multiplicación de la creación de firmas de menor tamaño dedicadas a elaborar productos editoriales.

En este devenir algunas editoriales se caracterizaron por sostener políticas editoriales que configuraron un catálogo con publicaciones sobre temas vinculados a espiritualidad, a pastoral y a religión. Un análisis de algunas de esas empresas editoriales y una revisión de sus catálogos permite una aproximación al lugar que ocupan las peregrinaciones como temática dentro de su producción. Para ello se han consultado fuentes como catálogos, publicaciones institucionales y periódicas, información de repositorios y análisis de investigadores sobre el tema.

BACKGROUND Patients with a prior coronary artery bypass graft (CABG) may have a need for repeat revascularization, which is typically attempted first via percutaneous coronary intervention (PCI) of either a bypass graft or native vessel. Long-term outcomes of native vessel compared to graft PCI after CABG have not yet been explored in a large institution study.
METHODS Patients with history of prior CABG who underwent PCI at our institution during 2010-2018 were included. Baseline characteristics and long-term outcomes of up to 5 years were compared between native vessel and bypass graft PCI groups. Cox regression was used to adjust for significant covariates in estimation of risk and calculation of hazard ratios.
RESULTS During the study, 4,251 patients with a prior CABG underwent PCI. Native vessel PCI represented 67.1% (n=2,851) of the cohort. After adjusting for significant covariates, bypass graft PCI compared to native vessel PCI had a higher risk of overall mortality (HR 1.15; 95% CI, 1.04-1.29; p<0.05), all-cause readmission (HR 1.16; 95% CI, 1.1-1.3; p<0.05), readmission for PCI (HR 1.25; 95% CI, 1.13-1.38; p<0.05), readmission for heart failure (HR 1.16; 95% CI, 1.06-1.26; p<0.05), and composite of myocardial infarction and revascularization (HR 1.23; 95% CI, 1.12-1.35; p<0.05).
CONCLUSIONS Among patients with prior CABG, bypass graft PCI compared to native vessel PCI was associated with higher risk of adverse long-term outcomes.

Published: March 2022

We report a case of a tracheal foreign body caused by a sewing needle. After about four months, the patient showed delayed dry cough and hemoptysis. The sewing needle that pierced the tracheal wall damaged the aorta, and we performed endovascular stenting to prevent arterial bleeding and removed it under a bronchoscope. The patient smoothly recovered after the operation. This case proves that treatment strategies for patients with foreign bodies in the trachea can be individualized.

Published: March 2022

Background: Infective endocarditis (IE) with involvement of the aortic root is associated with high short-term mortality and morbidity. Long-term data are sparse, and the existing studies with long-term data are restricted by a low number of patients and do not report mortality risks of different age groups.
Objective: This study examined the all-cause mortality risk postoperatively of patients with first-time IE who underwent aortic root replacement (ARR), according to age at the time of surgery, with one and 10 years follow-up.
Methods: Patients with first-time IE who underwent ARR surgery from 2000-2016 were identified in Danish nationwide administrative registries and divided into age groups: ≤60, 61-74, and ≥75 years. We compared one- and 10-year mortality risk using multivariable Cox regression across the three age groups.
Results: We identified 258 patients who underwent ARR (26.0% female, 42.6% with prosthetic valves, median age 64 years (IQR 55-73), of whom 98, 112, and 48 patients were ≤60 years, 61-74 years, and >75 years, respectively. The corresponding in-hospital mortality risk was 10.2%, 22.3%, and 29.2% (P = .01), respectively. The one-year postoperative mortality risk was 17.3%, 28.6%, and 33.3% (P = 0.05), while at 10 years after surgery, it was 31.8%, 62.9%, and 77.1% (P < 0.01), respectively. The adjusted 10-year hazard ratio was higher in the 61-74 and >75-year age groups (HR 1.94 [1.18-3.16] and 2.46 [1.35-4.49]) compared with the ≤60.
Conclusion: Aortic root replacement in patients with first-time IE was associated with a high in-hospital and one- and 10-year mortality with worse outcomes with age.

The aim of this study was to estimate the prevalence and risk factors associated with cervical cancer in priority municipalities of the Marajó archipelago. We conducted a study from March 2013 to February 2015 in four municipalities of Marajó. Women were recruited through oral communication. After signing the informed consent form and answering a structured questionnaire the women underwent the Papanicolaou test. The descriptive analyses were performed using frequency distribution and by medians with the standard deviation. The association of risk factors with cervical cancer was evaluated through non-parametric tests. A total of 405 women was included, with a mean age of 40.5 years. The majority had low literacy level and 42% living with a monthly family income below U$ 200. Suggestive results of invasive cervical cancer (ICC) were demonstrated in seven samples, with an overall prevalence of 1.7% and a total of 75 cases of cellular atypia was observed (18.5%). The results of ICC were more expressive between women without full primary education (p=0.0481) and between housewives (p=0,0219). We demonstrated a high prevalence of CC in isolated municipalities of the Marajó archipelago, Brazilian Amazon. Furthermore, the observed prevalence was vastly higher than that found in northern Brazil, which has the most worrisome picture in the country. CC cases were more frequent among women with low literacy level and among those who declared themselves homemakers. Our results emphasize the necessity for improvement of the screening program in the region.
Landuse Patterns, Air Quality and Bird Diversity in Urban Landscapes of Delhi
Authors: Kumar V.
Published: March 2022

In the present paper we attempted to explain the relationships among the landuse pattern, levels of air pollutants and bird diversity based on data from 5 sampling sites in Delhi. Five landuse categories- percent built up area, tree cover, park area and barren area were recognized in the study area. The objective of this study is to find out the effects of landuse changes on air pollution and bird diversity and whether birds can serve as indicator of landuse changes and air pollutants. The levels of six air pollutants (PM10, PM2.5, NOX, SO2, Ozone and Benzene) from the monitoring stations were used. The bird diversity was assessed using conventional measures. All the sites showed remarkable differences with respect to each of the five landuse categories, air pollution levels, and bird diversity. The results suggest that landuse changes influence air pollution and bird diversity and some bird species can be used as indicator of landuse change and air pollution.

Authors: Belfethi L.
Published: March 2022

This is the first study on the diet of the Great Cormorant wintering in Algeria. It is carried out in Beni Haroun, the largest dam lake in the country, in north-east of Algeria. The trophic menu of Phalacrocorax carboin this lake is based on four species of fish; Abramis bramas, Carassius carassius, Barbus barbus and Cyprinus carpio. However, Barbus barbus and Carassius carassius represent the two most important species in Great Cormorant’s diet. The total consumed biomass is 155,364.18 g, and the average biomass contained in each pellet varies between 330.7 and 2,953 g. The biomass of consumed fish varies between 36.89 g and 2,501 g. The size of the caught fish records values ​​between 13.7 cm and 52.49 cm. The number of consumed fish per pellet varies between 1 and 9. The results show that the great cormorant of Beni-Haroun Dam Lake consumes between 573 g and 2,353.3 g of fish per day and between 49.8 t and 185 t each month. However, the highest value is recorded in January (between 81.5 and 300.5 t). The Great Cormorant of Beni-Haroun dam lake could have a significant impact on continental and recreational fishing at this site.
