Allelopathic effect of sunflower residues on some soil properties and growth parameters of wheat, bean and flax crops
Authors: Flayyih Taisir M. , Almarie Ahmed A.
Published: December 2022

Allelopathic effects of the sunflower verities Helianthus annuus residues were evaluated on some soil properties and their potential against growth parameters of the proposed successive crops Wheat Triticum aestivumL., Broad Bean Vicia fabe L. and Flax Linum UstatissmimL. Sunflower plants were chopped and incorporated with field soil after getting seed, and then successive crops were cultivated. The sunflower residues have reinforced the soil with the macronutrients considered essential for the germination of any crop. The soil organic matter content and the percentage of organic carbon in the ground were increased. Significant suppression of broad bean and flax crops was observed, while the sunflower residues did not affect wheat growth. The results obtained showed that broad bean and flax crops are not recommended to grow after the sunflower crop to avoid losses due to the negative allelopathic potential of these crops. Sunflower residue incorporation may provide multidimensional benefits for better weed control, enhanced soil health, and higher seed yield of wheat.

Authors: David Dorely , Felipe Alzate Andrés , Rojano Benjamín , Copete-Pertuz Ledys S. , Echeverry Ricardo
Published: December 2022

The increase in the demand for Hass avocado has brought a rise in the generation of inedible waste such as peel and seed, by-products that are rich in bioactive substances. In the present study, aqueous, ethanolic, and supercritical fluid extracts were obtained from fresh seed and dry seed, which were analyzed to determine the antioxidant capacity measured through 2,2-diphenyl-2-picrylhydrazyl free radical (DPPH); 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid (ABTS), ferric reducing antioxidant power (FRAP) and oxygen radical absorbance capacity (ORAC) methods as well as the content of phenolic compounds. In addition, the antimicrobial activity of strains of food interest, such as Listeria monocytogenes, Salmonella enterica Typhimurium and Escherichia coli was evaluated. The ethanolic extract of fresh seed presented the highest antioxidant and antimicrobial activity. The aqueous extract of fresh seed registered a significant antioxidant capacity but an absence of antimicrobial activity. In contrast, the ethanolic extract of dry seed showed a representative antimicrobial activity on both S. enterica Typhimurium and L. monocytogenes, but low antioxidant activity. E. coli exhibited resistance against all the assessed extracts. The results from this work highlight the opportunity to consider the Hass avocado seed extracts as a novel alternative to replace or reduce the use of synthetic antioxidant and antimicrobial additives in food.

TOURISM POLICY MAKING DURING AN EMERGENCY: The Case of Yogyakarta City during COVID-19 Pandemic
Authors: Sari Sarah Meirina , Damanik Janianton
Published: December 2022

This study describes the public policy making process in Yogyakarta during the COVID-19 pandemic by determining the level of consistency of the government policy in opening and closing tourist attractions and its relationship to the decision of the possession of a COVID-19 free letter. The qualitative method was used because the approach was deemed capable of identifying various perspectives and points of view of the reality related to the process of tourism policy making during the COVID-19 pandemic condition in Yogyakarta City. The results showed that policies made were plagued by lack of adequate preparation and consistency. Not all tourist destinations were closed during the pandemic to prevent the spread of COVID-19. The decision did not have strong legality because as it was based on executive orders. Consequently, weak policy framework had adverse impact on cases of COVID-19. The surge in COVID-19 cases was also as a result of disagreement among the executives on the kind of sanctions that were meted out to violators of health protocols and the ineffectiveness of sanctions given. The implementation of the COVID-19 free letter for tourists from certain zones did not guarantee that visitors were free from COVID19. Policy recommendations for inconsistent and unequivocal policy implementation are expected to be further formulated. Thus, the policy implementers could adopt a flexible approach in interpreting policies in a proper manner.

Published: December 2022

This study aims to analyze the effectiveness of the service for handling the refugee from abroad in Kupang by the Regional Government of Kupang in collaboration with IOM after the delivery from the Kupang Immigration Detention Center and to examine the factors that cause the ineffectiveness of the foreign refugee handling services. This study uses qualitative research approach that focuses on analyzing the services for handling refugees from abroad in Kupang based on the concept of good service characteristics. The study found that the implementation of services for handling refugees from abroad in Kupang has not been effective due to: lack of participation by the Kupang Regional Government, lack of maintenance in the facilities and infrastructure in the shelter, lack of human resources officers at the shelter, local government feels not responsible for handling refugees, health services are less responsive, language barriers, Kupang local government does not have a database of refugees from abroad, lack of knowledge on refugee status and human rights enforcement by immigration officers, the reactive attitude of the refugees that reduce the trust of the Kupang Rudenim. In conclusion, the effectiveness of refugees from abroad handling services in Kupang which is managed by the Kupang Regional Government in collaboration with International Organization for Migration (IOM) is still not optimal if judged based on good service indicators.
The Effect of Sanitation on Stunting Prevalence in Indonesia
Authors: Nizaruddin Nizaruddin , Ilham M. Irsyad
Published: December 2022

Preparing children from birth can boost productivity and competitiveness later in their lives. However, the occurrence of malnutrition and stunting during childhood period will reduce their productivity and increases the risk of non-communicable diseases later in their lives. This study examines the effect of sanitation, drinking water sources, and drinking water treatment on stunting in Indonesian children (0-59 months). This study analyses cross- sectional data from the 2014 Indonesia Family Life Survey (IFLS) 5 with 3,834 children living with their biological mothers. The Logistic Regression to estimate the coefficients is applied here. The results show that the variables of sanitation, drinking water sources, and drinking water treatment before consuming affected stunting. Children who consume tap water are less likely to be stunted (OR=0.81, 95% CI 0.66-0.99). Birth weight, economic conditions, and mother’s level of education also affect risk of stunting. Hence, to overcome the risk of stunting, the government have to accelerate the supply of basic sanitation, to protect the good quality of drinking water sources, and to promote the awareness of boiling water before consumption.

Memoria y patrimonio: una reflexión en torno al palimpsesto urbano-arquitectónico del Bosque de Chapultepec
Authors: Leal Menegus Alejandro , Pérez Ramos Yúmari
Published: December 2022

Cada época tiene sus búsquedas y derroteros; cada generación critica el estado de las cosas y aporta un nuevo sentido y rumbo al entorno construido. El testimonio que al respecto encontramos en el Bosque de Chapultepec es un condensado de esta memoria colectiva: un muestrario de planteamientos urbano-arquitectónicos de diferentes épocas que no sólo se adicionan al conjunto, sino que muchas veces se superponen entre sí y desdibujan. Esto resulta en una verdadera reescritura de la memoria, un palimpsesto urbano-arquitectónico. El sentido del presente texto es cuestionarnos la capacidad de transmitir la memoria desde la perspectiva de esta superposición de capas que ha ocurrido de forma más notoria en el Bosque de Chapultepec desde inicios del siglo XX. Es ésta una reflexión sobre cuáles de esas capas están destinadas a conservarse y cuáles a desaparecer, y en ese sentido, qué papel juega el patrimonio urbano-arquitectónico en ello.En este escenario, señalamos el destino del proyecto de la Segunda Sección de Chapultepec del arquitecto Leónides Guadarrama de 1964 en el marco de la última intervención al Bosque, coordinada por el artista Gabriel Orozco. La intervención de la década de 1960 representa una capa relevante que en partes ha sufrido transformaciones, en otras deterioro y algunas más el abandono total en ciertas estructuras que están al centro de diversas acciones del proyecto actual. Con este ejemplo buscamos señalar ciertas pistas sobre la forma de entender la memoria y el patrimonio en la actualidad y confirmar la falta de convergencia histórico-social.

El papel de los azúcares como moléculas de señalización en las plantas
Authors: Hernández-Bernal Alma Fabiola , Gregorio-Jorge Josefat , León Patricia
Published: December 2022

La conversión de la energía solar a energía química en las plantas se realiza a través de la fotosíntesis, que es el principal sostén para la vida en el planeta, ya que es en este proceso en el que se da la fijación del CO2 y como resultado final los azúcares, que son la fuente principal de energía para los tejidos no fotosintéticos de las plantas. Durante la evolución, los azúcares no solo fueron, sino son una fuente de energía para las plantas y adquirieron la función de moléculas señalizadoras; es decir, moléculas mensajeras que perciben y comunican las variaciones del estado energético de la planta a través de diversos receptores proteícos situados extracelular e intracelularmente. Tanto los monosacáridos (glucosa y fructosa) como los disacáridos (sacarosa y trehalosa) desencadenan diferentes vías de señalización que involucran la participación de diversas cinasas y factores de transcripción para modular la expresión de diversos genes relacionados con el crecimiento, desarrollo y respuesta al estrés de las plantas. El objetivo de esta revisión es proporcionar un panorama general de las fuentes que generan los azúcares, sus mecanismos de transporte, así como el conocimiento actual de la percepción y la señalización mediada por estos compuestos y su impacto en la vida de las plantas.

Abstract: In recent years, deep learning has had a significant impact on “how the world is adjusting to artificial intelligence”. Region-based Convolutional Neural Networks (RCNN), Faster R-CNN, Single Shot Detector (SSD), and You Only Look Once (YOLO) are a few of the well-known object identification techniques. When speed is prioritized above accuracy, YOLO outperforms others, with Faster-RCNN and SSD having greater accuracy. In order to execute detection and tracking efficiently, deep learning blends SSD and Mobile Nets. This method detects objects effectively without sacrificing speed.

Published: December 2022

Tillage of fallow fields in summer is shown to be important for obtaining high quality food grains. The need for the engineering calculation of working bodies is emphasized, since the existing tillage machines and tools do not fully ensure the implementation of this technological process. (Research purpose) To develop a methodology for engineering calculation of the working body parameters for continuous fallow field tillage in summer. (Materials and methods) An analysis of the working body design has been conducted. It reveals that some of the working bodies bring a significant amount of wet soil layers to the surface, and others do not ensure a stable processing depth (4-6 centimeters) or do not completely destroy weeds. An engineering calculation method is proposed. It takes into account the following parameters of the working body: the angles of setting the lower part against the motion line and against the horizon, the angle of setting the upper part against the horizon, the conjugation radius of the upper and lower parts, the length of the cutting edge. (Results and discussion) A working body design is created meeting the agrotechnical requirements. The following parameters of the working body design are obtained: the angle of setting the lower part against the motion line is within 38-42 degrees and against the horizon – within 15-18 degrees, the angle of the upper part in the longitudinal-vertical and transverse-vertical planes is within 38-42 degrees, the conjugation radius of the upper and lower parts is within 0.2-0.3 millimeters, and the cutting edge length is of 282 millimeters. (Conclusions) A methodology for engineering calculation of the designed working body parameters is developed. It enables continuous fallow field tillage taking into account the soil physical and mechanical properties and the required indicators of the technological process.
Characterizing Reflective Diary Writing as an Argumentative Activity Type
Authors: Svačinová Iva
Published: December 2022

This paper is focused on the practice of unsolicited, reflective diary writing as an act of externalizing internal dialogue. I suggest that it should be analyzed as an argumentative practice from the point of view of pragma-dialectics. In the first part of the paper, I demonstrate that internal communication can be examined from the perspective of pragma-dialectics because it is in line with its meta-theoretical principles (especially socialization and externalization). In the second part, I suggest that reflective diary writing should be conceived of as an argumentative activity type. I show that this practice is a conventionalized activity type that is preconditioned by implicit norms governing the conduct of argumentation.

A multiscale method for the effective selection of an eco-efficient solvent for the direct hydration of cyclohexene
Authors: Wang Xiaoda , Zhao Yuqing , Han Lumin , Li Ling , Kiss Tony
Published: December 2022

A rational multiscale method is proposed for selecting an economical and
sustainable solvent for the direct hydration of cyclohexene. At the
molecular scale, liquid-liquid phase equilibrium was estimated using
group contribution methods to rapidly screen the potential solvent
candidates from a range of organics using a novel evaluation index. At
the reactor scale, these candidates were experimentally investigated to
pick out the solvents that could significantly improve the conversion,
without introducing side reactions and deactivating the catalyst. At the
process scale, the total annual cost and CO2 emission were calculated to
evaluate the eco-efficiency. Using this new multiscale method,
acetophenone was selected as an eco-efficient solvent from over 100
organics, resulting in the reduction of TAC by 7.8% and CO2 emission by
16.9% in the production process. Also, acetophenone led to the increase
of cyclohexanol yield from 12.3% to 27.6% without the occurrence of
side reactions or catalyst deactivation.

Effect of residual stress on fatigue crack growth behavior of 2024-T3 and 7075-T6 aluminum friction stir welded joint
Authors: Guo Yanning , Ma Yu E , Yao Yao
Published: December 2022

Since aluminum alloys have the low melting point and high thermal
conductivity, friction stir weld (FSW)has been successfully used in the
aerospace industry as an alternative to traditional welding methods. In
the service of FSWed structures, the residual stress and external load
would result in a secondary deformation and residual stress
redistribution. Therefore, it is necessary to investigate the effect of
residual stress on the FSWed fatigue responses. This paper studied the
fatigue crack growth behavior of 2024-T3 and 7075-T6 homogeneous and
dissimilar FSWed joints. The finite element model was built to calculate
the fatigue crack growth rate of FSWed specimen, and the results were
compared with the experiment results. It was demonstrated that residual
stress significantly affected on the fatigue crack growth rate. Tensile
residual stress promoted the crack growth, and it offset the decrease of
fatigue crack growth rate by grain refinement. The numerical results
also indicated that the longitudinal residual stress showed the greatest
effect on the crack deflection. Under the same welding speed, the
fatigue crack growth rate of 2024 increased with the increasing
rotational speed. For the same rotational speed, the fatigue crack
propagation rate of 7075 decreased with the increasing welding speed.
A Verification Suite of Test Cases for the Barotropic Solver of Ocean Models
Authors: Bishnu Siddhartha , Petersen Mark R. , Quaife Bryan , Schoonover Joseph Arthur
Published: December 2022

The development of any atmosphere or ocean model warrants a suite of
test cases to verify its spatial and temporal discretizations, order of
accuracy, stability, reproducability, portability, scalability, etc. In
this paper, we present a suite of shallow water test cases designed to
verify the barotropic solver of atmosphere and ocean models. These
include the non-dispersive coastal Kelvin wave; the dispersive
inertia-gravity wave; the dispersive planetary and topographic Rossby
waves; the barotropic tide; and a non-linear manufactured solution.
These test cases check the implementation of the linear pressure
gradient term; the linear constant or variable-coefficient Coriolis and
bathymetry terms; and the non-linear advection terms. Simulation results
are presented for a variety of time-stepping methods as well as two
spatial discretizations: a mimetic finite volume method based on the
TRiSK scheme, and a high-order discontinuous Galerkin spectral element
method. We explain the strategies that need to be adopted for specifying
initial and non-periodic boundary conditions on hexagonal meshes.
Convergence studies of every test case are conducted with refinement in
both space and time, only in space, and only in time. The convergence
slopes match the expected theoretical predictions.
Fine structure of tremor migrations beneath the Kii Peninsula, Southwest Japan, extracted with a space-time Hough transform
Authors: Sagae Kodai , Nakahara Hisashi , Nishimura Takeshi , Imanishi Kazutoshi
Published: December 2022

Tectonic tremors occurring on subducting plate boundaries are known to
migrate at various timescales and migration speeds. Spatiotemporal
patterns of tremor migration are key to investigating the rupture growth
of slow earthquakes. However, spatiotemporal patterns are not
sufficiently simple to visually define tremor migrations. This study
developed a space-time Hough transform to objectively extract tremor
migrations. The space-time Hough transform enables the extraction of
multiple tremor migrations with various durations, migration directions,
and migration speeds. We applied this method to a catalog of tremors for
the period from 2012 to 2014, which was determined from the data
analysis of a dense seismic array deployed in the Kii Peninsula,
Southwest Japan. We successfully extracted 1,010 tremor migrations with
durations ranging from 10 min to 24 h. Along-strike migrations
propagating southwestward were predominant in the northeastern part of
the Kii Peninsula, whereas those propagating northeastward were
principal in the southwestern part. Regarding the along-dip direction,
tremor migrations propagating in the up-dip directions were predominant
in the deep part, and those propagating in the down-dip directions were
principal in the shallow part. The patterns of along-strike migrations
were related to the distribution of tremor energies, suggesting that
tremor migrations may be controlled by heterogeneous structures of
frictional properties on the plate interface. We further found that the
migration speed is proportional to the inverse of the square root of the
duration. This relation implies that a diffusion process controls the
growth of fault ruptures behind tremor migrations.
Ocean air masses dominate the land-surface atmospheric water cycles in the coastal areas of Liaodong Bay: Insights from stable isotopes
Authors: Du Yiyuan , Wen Ri Hong , Panthee Shristee , Zakari Sissou , Song Liang , Liu Wen-Jie , Yang Bin
Published: December 2022

Long-term atmospheric water vapor hydrogen (δ2H), oxygen (δ18O), and
deuterium excess (d-excess) can provide unique insights into the
land-atmosphere coupling processes. The in-situ measurements of
atmospheric water vapor δ2H, δ18O, and d-excess were conducted above a
reed wetland of Liaodong Bay (2019-2020). We found significant
inter-annual variations in atmospheric water vapor isotopes between the
two growing (May-September) seasons. The δ2H, δ18O, and d-excess of
atmospheric water vapor exhibited different seasonal and diurnal cycles
respect to the vertical (i.e., 1 m, 3 m, and 5 m) measurement heights,
especially in 2019. The isotopic differences of atmospheric water vapor
among vertical measurement heights were more evident in the daytime
(8:00-20:00 LST) than at night (20:00-8:00 LST). Rainfall events had a
direct impact on the diurnal patterns of water vapor isotopes, and the
influences depended on rainfall intensities. However, only week
correlations existed between water vapor isotopes and local
meteorological factors (R2 = 0.01-0.16, P < 0.001), such as
water vapor concentration (w), relative humidity (RH), and surface air
temperature (Ta). Based on the back-air trajectory analyses, the
spatial-temporal dynamics of atmospheric water vapor isotopes highly
synchronized with monsoon activities. The dominant air masses in this
region mainly arose from ocean sources, which contributed to 62.1 ±
12.2% (49.4-84.5%) of the total air moisture. High d-excess
consistently followed the strong monsoon activities, suggesting
predominating impacts of ocean air masses from the East Asian monsoon
region. High-resolution measurements of atmospheric water vapor isotopes
will improve our understanding of the hydrological cycles in coastal
areas.

Published: December 2022

Composting is recognized as a sustainable waste management approach in which microorganisms treat and stabilize biodegradable waste under aerobic conditions to obtain compost as a final product. In this paper, composting of biowaste in a rotary drum composter (closed system) and an open container (open system) was compared. Temperature, pH, electrical conductivity, a carbon-to-nitrogen mass ratio (C/N ratio) and contents of moisture, carbon and dry and volatile matter, were measured during composting. Results showed decreasing profiles for moisture, volatile matter, and carbon contents, as well as for the C/N ratio, while increasing profiles for the dry matter content and electrical conductivity during composting in both systems. Leachates were formed only during the first three days of composting and were characterized with high organic loads, high ammonia concentrations, low pH, and high conductivity and turbidity. The organic matter content data during the composting process were analysed according to the first order kinetic model. Results suggested that there was a difference in the rate of organic matter decomposition, which was higher when composting in the open vessel than in the rotary drum composter.
Associations of mid- and late-life severe hypoglycemic episodes with incident dementia among patients with type 2 diabetes: A population-based cohort study
Authors: Alkabbani Wajd , Maxwell Colleen J , Marrie Ruth Ann , Tyas Suzanne L , Lega Iliana C , Gamble John-Michael
Published: December 2022

  

Objective: Severe hypoglycemia is associated with an increased risk of dementia. We examined if the association is consistently present for mid-life and late-life hypoglycemia. 

Methods: Using healthcare data from Population Data BC, we created a base cohort of patients with incident type-2 diabetes aged ≥40 years. Exposure was the first occurrence of severe hypoglycemia (hospitalization or physician visit). We assessed exposure vs no exposure in mid-life (age 45-64) and late-life (age 65-84) cohorts. Index date was the later of the 45th birthday (mid-life cohort), 65th birthday (late-life cohort) or diabetes diagnosis. Those with hypoglycemia or dementia before index date were excluded. Patients were followed from index date until dementia diagnosis, death, emigration or December 31, 2018. Exposure was modeled as time-dependent. We adjusted for confounding using propensity score weighting. Dementia risk was estimated using cause-specific hazards models with death as a competing risk. 

Results: Of 221,683 patients in the mid-life cohort, 1,793 experienced their first severe hypoglycemic event. Over a median of 9.14 years, 3,117 dementia outcomes occurred (32 among exposed). Of 223,940 patients in the late-life cohort, 2,466 experienced their first severe hypoglycemic event. Over a median of 6.7 years, 15,997 dementia outcomes occurred (158 among exposed). The rate of dementia was higher for those with (vs. without) hypoglycemia in both the mid-life (hazard ratio, 95% confidence interval=2.85, 1.72-4.72) and late-life (2.38, 1.83-3.11) cohorts.

Conclusion: Both mid-life and late-life hypoglycemia were associated with approximately double the risk of dementia, indicating the need for prevention throughout the life-course of diabetes.

Considering the importance of technology and the role of leadership in education, this study aimed to analyses the impact of digital leadership on teachers' acceptance and use of digital technologies. This research was done involving 27 elementary schools in one city. Six teachers from each school were randomly selected to be the study samples. So, there were 162 teachers involved in the research samples. The research data were collected by distributing questionnaires to measure digital leadership and questionnaires to measure teachers' acceptance and use of digital technology. The collected data were analyzed using simple regression analysis with the help of SPSS 20 for windows. The study showed that the significance of the regression direction was 8,581 with a significance (sig.) of 0.000, which indicates that the regression direction is significant. Therefore, it can be concluded that digital leadership significantly influences teachers’ acceptance and use of digital technology. Since digital leadership is needed to increase education quality, it is suggested that the school principals enhance their digital leadership. Since this research was only limited to two variables, it is necessary to do further research involving more independent variables, considering the various factors that may affect the acceptance and use of technology.

According to experts, yearly flu rate can constitute 5–20% in adults and 20–30% in children; and in case of development of a pandemic, a number of those suffering from flu‑like infection can be increased by 50%. Vaccination against influenza and properly used non‑specific prevention can exclude seeking medical aid and hospitalization due to high incidence of COVID‑19 and reduce the load to the healthcare system. Research purpose: examine awareness of children, young people and adults about signs of flu, methods of specific and non‑specific prevention and their use in life. Materials and methods: the research was performed in three groups based upon online questioning: 270 adults aged 25 to 60, 1,112 students from universities and colleges aged 15 to 24, 101 schoolchildren aged 11 to 17. The questionnaire included sets of questions that reflected awareness of and commitment of population to measures of specific and nonspecific prevention. The students were questioned from January to February 2022. The obtained results show high flu and ARVI morbidity, insufficient hygienic education and commitment of citizens to the measures of specific and non‑specific flu and ARVI prevention. To improve the situation, not just hygienic education is required, but also education of medical workers, parents, healthcare workers, journalists and correspondents of mass media regarding flu and ARVI prevention, availability of vaccine prevention centers, and consultations of pediatricians and therapists regarding the issues of specific prevention.
