The breakup of multicultural families and grandmothers’ child-rearing experiences: through grounded theory.
Authors:   Korean Academy of Multicultural Welfare, Jang Soon-Mi , Han Jeongwoo
Published: May 2024

The increase in multicultural families has simultaneously led to an increase in the number of multicultural families broken up due to divorce, bereavement, runaway, etc. The expansion of multicultural families in rural areas has led to the phenomenon of grandmothers taking full responsibility for raising their grandchildren. This study explored the parenting experiences of grandmothers in multicultural families using grounded theory. The core category was ‘Embracing the burden of raising children and finding the meaning of the experience of raising children in old age.’In axial coding, the central phenomenon was 'acquired burden of parenting', the causal condition was 'dissolution of multicultural family', the contextual condition was ‘entrenched maternal instinct', the mediating condition was 'cooperative parenting system', and the action/interaction were ‘the joys and sorrows of parenting’ and ‘grandmother-style parenting strategies’. The result was ‘a life of nurturing that has become a value of existence.’ Upon the understanding the grandmothers’childcare experience through their vivid voices, social welfare support measures were presented.

Is functional MRI meaningful in migraine?
Authors: Öcal Ruhsen , Gürsoy Hasoğlan Merve
Published: May 2024

Functional magnetic resonance imaging (fMRI) is an imaging method that enables us to understand brain anatomy, mapping and its function. While fMRI was previously used in experimental studies, it has now been used in clinical studies. Imaging in fMRI is based on measuring the increase in regional blood flow caused by cortical activation. fMRI indirectly demonstrates neural activation by detecting increases in oxygenation. fMRI relies on the sensitivity of magnetic resonance signals to changes in deoxyhemoglobin levels or perfusion, reflecting the metabolic and hemodynamic responses associated with neural activation.
Imaging is arranged in the clinic for primary headaches if needed for a differential diagnosis. However, imaging studies are utilized in scientific research to elucidate the pathophysiology. Migraine is a common episodic disorder characterized by recurring attacks. Investigating the functional structure of the brain during both attack and interictal periods is crucial in understanding migraine pathology. However, capturing patients' migraine attacks for monitoring purposes without treatment is considered unethical in many countries. Moreover, conducting such studies is hindered by the requirement for prolonged hospital stays and extended imaging times, which significantly increase costs. Despite the challenges of conducting research in migraine patients, fMRI stands out as an excellent imaging method for investigating the functional brain structures involved in this episodic disorder. Several fMRI studies have yielded valuable insights into the pathophysiology of migraine. fMRI is believed to offer valuable guidance in refining our understanding of migraine-specific mechanisms, facilitating biomarker studies for migraine activity, and elucidating abnormal functions in regions affected by migraine. Monitoring treatment response using biomarkers is anticipated to be an effective tool for identifying targets for migraine treatment, including assessing treatment efficacy in the development of new migraine-specific therapies.
Maternal serum vasohibin-1 and vasohibin-2 concentrations in pregnant women diagnosed with late fetal growth restriction or small for gestational age fetus
Authors: Bozoklar Ayça , Kale İbrahim , Özel Ayşegül , Yalçınkaya Cem , Muhcu Murat
Published: May 2024

Aims: Vasohibin 1, a member of the vasohibin family, is an inhibitor of angiogenesis, while vasohibin 2 stimulates angiogenesis. Placental expressions of vasohibins and their relationship with preeclampsia have been investigated, but their effects on intrauterine fetal growth are unknown. In this context, we aimed to investigate the concentrations of vasohibin 1 and 2 in the serum of pregnant women diagnosed with late fetal growth restriction (FGR) or small for gestational age (SGA) in the third trimester.
Methods: This prospective non-interventional cohort study was conducted on 81 pregnant women, 26 of whom were diagnosed with late FGR, 28 were SGA, and 27 were healthy controls. Three groups were compared in terms of serum vasohibin 1 and 2 concentrations in the third trimester.
Results: Three groups were similar in terms of demographic characteristics and gestational age at blood sampling for vasohibin 1 and 2 (p < 0.05). The median vasohibin 1 concentration was determined as 1227.41 ng/mL in the late FGR group, 1311.15 ng/mL in the SGA group, and 1391.38 ng/mL in the control group (p = 0.139). The median vasohibin 2 concentration was determined as 11.24 ng/mL in the late FGR group, 11.86 ng/mL in the SGA group, and 14.34 ng/mL in the control group (p = 0.198).
Conclusion: Serum vasohibin 1 and 2 concentrations were found to be similar in pregnant women diagnosed with late FGR and SGA and pregnant women with AGA fetuses. Vasohibin 1 and 2 are involved in the regulation of placental angiogenesis, but their roles in intrauterine fetal growth remain unclear.

Experiences of Malaysian primary healthcare providers with vaccine hesitancy: A qualitative study
Authors: Amzar Megat Hashim Megat Mohamad Amirul , Hanafi Nik Sherina Haidi
Published: May 2024

Introduction: Vaccine hesitancy was declared as one of the ten threats to global public health by the World Health Organization in 2019. It undermines the effort towards eradication of vaccine-preventable diseases. Healthcare providers, who are directly involved in vaccination services and vaccine advocacies, are important in combating vaccine hesitancy. Studies have shown that vaccine refusers have various reasons for refusal including distrust towards healthcare providers. Hence, it is important to understand healthcare providers’ perspectives. This study aimed to explore primary healthcare providers (PHCPs)’ experiences in dealing with vaccine hesitancy.
Methods: This qualitative study was conducted among public PHCPs across six states in Malaysia. Purposive and snowball sampling methods were used. Fifteen primary healthcare doctors and nurses underwent in-depth interviews. Recruitment was stopped when data saturation was achieved. Data were thematically analysed.
Results: Four themes emerged: 1) views towards vaccination and vaccine hesitancy, 2) disparity in strategies and resources used among PHCPs, 3) fixed-minded vaccine deniers and religious incompatibility: the two towering hurdles and 4) negative impact after encounters with vaccine hesitancy.
Conclusion: Malaysian PHCPs encounter negative experiences with vaccine hesitancy, impacting them negatively. These experiences are attributed to the challenges and lack of standardised resources for reference. These findings suggest the development of a more flexible policy, a training module inclusive of all professional roles and a standardised repository of resources for managing vaccine hesitancy.

Published: May 2024

Abstract. In this work we present a super-resolution approach to derive high spatial and temporal resolution ocean colour satellite datasets. The technique is based on DINEOF (Data Interpolating Empirircal Orthogonal Functions), a data-driven method that uses the spatio-temporal coherence of the analysed datasets to infer missing information. DINEOF is now used to effectively increase the spatial resolution of satellite data, and is applied to a combination of Sentinel-2 and Sentinel-3 datasets. The results show that DINEOF is able to infer the spatial variability observed in the Sentinel-2 data into the Sentinel-3 data, while reconstructing missing information due to clouds and reducing the amount of noise in the initial dataset. In order to achieve this, both Sentinel-2 and Sentinel-3 datasets have undergo the same preprocessing, including a comprehensive, region-independent, and pixel-based automatic switching scheme for choosing the most appropriate atmospheric correction and ocean colour algorithm to derive the in-water products. The super-resolution DINEOF has been applied to two different variables (turbidity and chlorophyll) and two different domains (Belgian coastal zone and the whole North Sea), and the submesoscale variability of the turbidity along the Belgian coastal zone has been studied.
Characterizing ground ice content and origin to better understand the seasonal surface dynamics of the Gruben rock glacier and the adjacent Gruben debris-covered glacier (southern Swiss Alps)

Published: May 2024

Abstract. Over the recent years, there has been focused international efforts to coordinate the development and compilation of rock glacier inventories. Nevertheless, in some contexts, identifying and characterizing rock glaciers can be challenging as complex conditions and interactions, such as glacier-rock glacier interactions, can yield landforms or landform assemblages that are beyond a straightforward interpretation and classification through ordinary visual means alone. To gain a better understanding of the spatial and temporal complexity of the ongoing processes where glacier-permafrost interactions have occurred, the characterization of the subsurface of the Gruben rock glacier and its adjacent complex contact zone is quantitively assessed using a petrophysical joint inversion (PJI) scheme, based on electrical resistivity (ERT) and refraction seismic (RST) data. Surface dynamics are assessed using both in-situ and close-range remote sensing techniques to monitor daily and seasonal displacements and to monitor landform-wide surface changes at high spatial resolution, respectively. Both the geophysical and geodetic surveys allowed to identify two zones: the rock glacier zone and the complex contact zone where both permafrost and embedded surface ice are present. In the complex contact zone extremely high ice contents (estimated up to 85 %) were found. Widespread supersaturated permafrost conditions were found in the rock glacier zone. Surface displacement rates in this zone are typical of permafrost creep behaviour, with a gradual acceleration in late spring and a gradual deceleration in winter. Moreover, the coherent nature of the rock glacier zone surface deformation contrasts with the back-creeping and slightly chaotic surface deformation of the complex contact zone. Favouring a multi-method approach allowed a detailed representation of the spatial distribution of ground ice content and origin, which enabled to discriminate glacial from periglacial processes as their spatio-temporal patterns of surface change and geophysical signatures are (mostly) different.
Using regional relaxation experiments to understand the development of errors in the Asian summer monsoon
Authors: Martin Gill M. , Rodríguez José M.
Published: May 2024

Abstract. We describe the use of regional relaxation (“nudging”) experiments carried out in initialised hindcasts to shed light on the contribution from particular regions to the errors developing in the Asian summer monsoon. Results so far confirm previous hypotheses that errors in the Maritime Continent region contribute substantially to the East Asia summer monsoon (EASM) circulation errors through their effects on the western North Pacific subtropical high. Locally forced errors over the Indian region also contribute to the EASM errors. Errors arising over the Maritime Continent region also affect the circulation and sea surface temperatures in the equatorial Indian Ocean region, contributing to a persistent error pattern resembling a positive Indian Ocean dipole phase. This is associated with circulation errors over India and the strengthening and extension of the westerly jet across southeast Asia and the South China Sea into the western Pacific, thereby affecting the Asian summer monsoon (ASM) circulation and rainfall patterns as a whole. However, errors developing rapidly in the deeper equatorial Indian Ocean, apparently independently of the atmosphere errors, are also contributing to this bias pattern. Preliminary analysis of nudging increments over the Maritime Continent region suggests that these errors may at least partly be related to deficiencies in the convection and boundary layer parameterisations.
Experimental Evaluation of Wind Turbine Wake Turbulence Impacts on a General Aviation Aircraft
Authors: Rogers Jonathan
Published: May 2024

Abstract. Continued development of wind farms near populated areas has led to rising concerns about the potential risk posed to general aviation aircraft when flying through wind turbine wakes. There is an absence of experimental flight test data available with which to assess this potential risk. This paper presents the results of an instrumented flight experiment in which a general aviation aircraft was flown through the wake of a utility-scale wind turbine at an operating wind farm. Wake passes were flown at different downwind distances from the turbine, and data was collected on the orientation disturbances, altitude and speed deviations, and acceleration loads experienced by the aircraft. Videos were also collected providing qualitative information about the disturbances encountered in the wake. Results show that flight disturbances were small in all cases, with no difference observed between flight data inside and outside the wake at distances greater than six rotor diameters from the turbine. Closer than six rotor diameters, small load factor and orientation disturbances were noted, but were commensurate with those experienced in light or moderate atmospheric turbulence. Overall, the loads and disturbances experienced were far smaller than those that would risk causing loss of control or structural damage.

Authors: Hasmukh Kumar  , H. K. Mittal  , R. S. Singh  , R. C. Purohit  , P. K. Singh
Published: May 2024

Development programmes for optimum utilization of natural resources are now increasingly planned on watershed basis. Proper planning and management of a watershed require detailed data viz. hydrologic behaviour of watershed, slopt;, rainfall pattern, land capability classification, land use etc., which govern the amount of runoff and soil loss produced by rainfall. Remote sensing and GIS techniques can be used successfully for the integration and analysis of above properties. In the present study remote sensing data are used for land information whereas GIS has been used for the integration of various thematic maps to delineate the areas suitable for adopting soil and water conservation measures. The major soil and water conservation measures proposed in Kalora-II micro-watershed of district Udaipur (Rajasthan) were contour bund, puerto rico terrace, stone wall terrace for arable land and contour trench, staggered trench, v-ditch, silvi-pasture development for non-arable land. A water harvesting structure of capacity 8.32 ha-m was also proposed for supplementary irrigation to rabi crops.
Development of Solar Tunnel Dryer For Industrial Use
Authors: Pratap Singh  , N.S. Rathore  , A.N. Mathur
Published: May 2024

This paper deals with a technology for drying of Di-basic calcium phosphate (DCP) through solar energy. For drying this material a solar tunnel dryer was designed and commissioned at MIS Phosphate India Limited, Udaipur. It is semi-cylindrical shaped tunnel dryer having a loading capacity of 1.5 tonne per batch. Two such tunnels were installed in series to accommodate 3.0 tonne of material. It is observed that maximum temperature inside the solar tunnel dryer was 62°C and 50°C on a summer and winter day respectively, which is about 15°C higher than ambient temperature. Total 16 h were needed for drying DCP up to the safe moisture content during winter seasons while total 12 h were needed during summer seasons for reducing moisture content from 37.3% to 9.4%. The solar tunnel drying reduces moisture content to around 10%. Thereafter, the moisture content is reduced to around 5% in a spin-flash dryer for final delivery to market.

Authors: Arun Kumar  , T C Thakur
Published: May 2024

An experiment was conducted at Crop Research Centre of G B Pant University of Agriculture and Technology, Pantnagar in Randomized Block Design to compare the performance of different types of subsoiler viz. conventional curved leg, conventional straight leg, winged straight leg and winged with shallow leading tines on the basis of draft, soil disturbance and specific draft at working depths of250, 300, 350 and 400 mm. The soil of the experimental field was silty clay loam (Sand 31%, Silt 37%, and Clay 32%). Results have shown the critical depth of conventional curved leg subsoiler at about 350 mm depth of operation. However, the critical depth for other subsoilers was not observed even upto 400 mm depth. At 350 mm working depth, the draft force for winged subsoiler with shallow leading tines increased by 39.75% and 31.81% over conventional curved leg and straight leg subsoilers while the soil disturbance increased by 3.03 (203.25%) and 2.35 (135.42%) times, thereby, reducing the specific draft by 53.90% and 44.00%, respectively

Authors: G. R. Ramakrishna Murthy  , R. Naik  , K. P. Pandey
Published: May 2024

Performance prediction of a new salt like fertiliser is crucial before it is used in a large solar pond. The heat transfer process in solar pond is modelled and implemented through a computer program for assessing the thermal performance in terms of temperature of lower convective zone (LCZ). The programmed model is validated using the real time data of a working solar pond. The model is found to be in good agreement with the observed data. The program is tested for predicting the solar pond performance using a fertiliser salt, Muriate of Potash. The solar pond is observed to attain steady state after 10, h month of pond operation. The pond started in April attained peak LCZ temperatures quicker than that started in January. The pond behavior is well explained by superimposing temperature surface and contours.

Published: May 2024

A simple, but efficient, technological device is clay pitcher, which entails creation of rural employment, savings of scarce water resources, maximizing yield and a reduction in irrigation frequency. For the practical application of pitcher irrigation there is need to have basic information and understanding of system which leads to design criteria for pitcher irrigation. The saturated hydraulic conductivity, Ks, of pitchers is considered the most important factor affecting the outflow rate from pitchers. A modified falling head method and a constant head method were used to measure the saturated hydraulic conductivity of eight pitchers selected from local producers in Udaipur. The two methods of measuring Ks were found accurate. However, procedure for falling head method was faster and simpler. Ks varied from 360.5 to 484.0 mm/day considering falling head method and from 398.6 to 574.4 mm/day in case of constant head method. While the conductance calculated was in the range of 13705837.54 to 17983403.85 mm2/day by falling head method and by constant head method it was in the range 15640326.92 to 21082408.74 mm2/day.

Transesterification process is now a easy and reliable method to prepare the biodiesel from different edible or non edible oil sources, but before going to transesterification, it is needed to select either single or double stage process to determine the amount of lye (catalyst) and alcohol required to transesterify the oil. In this study single stage method (base catalyst method) was followed to transesterify the Ratanjot because of its fatty acid content «1%). From the study the amount of Lye (NaOH) was found to be 8g per litre of oil. The optimum amount of alcohol for Ratanjot was found to be 350 ml per litre of oil by single stage process. The density, viscosity, acid number flash point and fire point of the biodiesel Obtained was 0.872 g/ml. 2.95Cst, 0.26 mg KOH/g. 175°C and 190°C respectively.

Authors: S. N. Jha
Published: May 2024

A simple and nondestructive method using portable near infrared spectroscopy (NIRS) was investigated to determine the total soluble solids (TSS) of orange juice. Juice from I 10 orange was squeezed and tqeir spectra in the range of 311.7 - 1124.8 nm wavelength were acquired using a portable Vis-NIR spectrometer and fibre optics as light transmitting medium. Sweetness in terms of total soluble solids contents of juice was determined using a digital refractometer. Whole samples were divided into two sets: calibration and validation; and partial least squares regression of spectral data in wavelength region from 703.3 to 1124.8 nm was performed. The standard errors of calibration and validation were found to be 0.47° and 0.4 FBrix, respectively, which are reasonably low. It indicates that sweetness of juice may be determined non-destructively using a portable NIR spectrometer without sacrificing accuracy as compared to that by a refractometer.

Rotary blades in strip-tillage practice are used to achieve advantages of lower draft requirement, better soil breakup and more efficient inversion and trash mixing. The study was aimed at development of three types of rotary blades for strip-tillage (namely, C-type, L-type, and RC-type) in order to reduce the energy requirement for tillage by optimizing the parameters which affect the cutting force of the rotary blades. For this reason the cutting force of the rotary blades and the equations for its surface area per unit volume of soil tilled as well as cutting angles were determined and computer programs to solve these equations were developed. Blade geometrical dimensions corresponding to the minimum and optimum blade surface area per unit volume of soil tilled and cutting angle were selected using the programs to fabricate the rotary blades. The developed and fabricated blades were evaluated in soil bin on the basis of specific work requirement. Investigations were carried out at three levels of number of blades per flange (2, 4, and 6 blades per flange), three levels of forward speed (1.4,2.5, and 3.6 km/h), and three levels of rotational velocity (110, 165, and 244 rpm). It was found that RC-type blade with less specific work requirement and more volume of soil tilled per bite had better performance than other blades. Specific work requirement increased with increase in number of blades per flange and rotary speed, while it reduced by increasing the forward speed. Specific work had an exponential relation with bite length, whereas linear relationship was observed with velocity ratio for all the blades tested.

A general framework for automating ginning process using computer-vision-based approach for online trash identification and removal is presented in this study. It involves trash identification using imaging and consequently trash classification and estimation using soft computing techniques of artificial neural network. A computer programme was developed to automate image capture, analysis and computing processes generating overall statistics of trash content in cotton lint. Measurement of trash features such as area, perimeter, convex perimeter, ferret meandiameter, ferret elongation, elongation, length and compactness yielded higher values in stick trash type as comparedto leaf objects. There was not much difference in breadth and roughness of these trash types. Designed back propagation classifier system correctly distinguished 60% trash types with 80-99% confidence measure (CM), 25% data with CM 40-80%, 10% data with CM 20-40% and 5% data left undefined or wrongly identified with CM less than 10%. Information on trash types present in cotton can be used to appropriately configure cleaning and ginning machineries. Overall benefit is increased bale value and energy savings that add to monetary gain. It also assists in online assigning of classer grade to processed bales

Debris flow events in the Blagoevgradska Bistritsa catchment (SW Bulgaria) become more frequent in the past few years. To localize the debris source along the tributary system, the Harsovska River is chosen in this study. During the observation period a torrential event was registered in June 2023. The synoptic situation, which caused the flood, is re-analyzed and also geomorphological research is made for depositional landforms in the river channel for the period 2019-2023. In the study, the alluvial sediments are defined by grain size and also by morphoscopic study of pebble-sized grains. During the field research, two critical flood-risk sites are pointed, located in the Harsovo hamlet. The data about past debris flow events are collected from residents of Harsovo with interviews regarding their experience in this issue. In the period of the study, the main part of debris nourishment in Harsovska catchment is provided by the tributary Marulevska River, where active mass movement processes are registered. However, the alluvial profiles of both rivers – Marulevska and Harsovska, showed an alternation of coarser and finer materials, resulting of turbulent and calm discharge. Such periodical change in the sedimentary environment of the two compound rivers demonstrates their unsteady torrential character. Regarding the fortification activities in this area, at the moment some new forestation has been noticed. Still, the species, used to fortify the river banks are not suitable for the climate and hydrological regime of the region. The channel fortifications, built in the middle of the 20th century, currently are not maintained properly, which puts under threat of future debris flow events the settlements and infrastructure along this catchment.
