Frustrated magnets can host numerous exotic many-body quantum and topological phenomena. GeNi2O4 is a three-dimensional S=1 frustrated magnet with an unusual two-stage transition to the two-dimensional antiferromagnetic ground state, while GeCu2O4 is a high-pressure phase with a strongly tetragonally elongated spinel structure and magnetic lattice formed by S=1/2 CuO2 linear chains with frustrated
In the present study the thermo-hydraulic characteristics of geyser in the cryogenic fuel transportation pipe of a liquid rocket is experimentally investigated using liquid nitrogen. The typical thermo-hydraulic appearances are characterized and analyzed in the geyser process to effectively recognize the occurrence of geyser in practical engineering. The effect of interfering factors such as heat
The COVID-19 pandemic caused a global disruption to higher education, especially in engineering education, where many teaching and learning activities are difficult or impossible to conduct online. This study examines the changes in the students’ experiences of this disruption using a 26-item process-oriented course experience questionnaire (CEQ) that was already in use in the Faculty of Engineeri
Numerical simulations have been conducted to investigate the effects of pin-fin arrangement and jet Reynolds number on heat transfer enhancement and flow characteristics of a concave confined jet impingement cooled surface conjugated with pin-fins. The results without a pin-fin are used as a baseline. Vortices and different sections of streamlines in the channel are employed to understand the flow
To reduce global HIV-1 incidence, there is a need to understand and disentangle HIV-1 transmission dynamics and to determine the geographic areas and populations that act as hubs or drivers of HIV-1 spread. In Sub-Saharan Africa (sSA), the region with the highest HIV-1 burden, information about such transmission dynamics is sparse. Phylogenetic inference is a powerful method for the study of HIV-1
Long-distance migration has evolved repeatedly in animals and covers substantial distances across the globe. The overall speed of migration in birds is determined by fueling rate at stopover, flight speed, power consumption during flight, and wind support. The highest speeds (500 km/day) have been predicted in small birds with a fly-and-forage strategy, such as swallows and swifts. Here, we use GL
Background: The aim of this study was to examine the effect of household food security on childhood anemia inBangladesh while controlling for socioeconomic and demographic factors.Methods: We used nationally representative Bangladesh Demographic Health Survey (BDHS) 2011 data for thisstudy, the only existing survey including anemia information and household food security. The sample included2171 c
In0.71Ga0.29As/InP (12/2 nm) quantum well MOSFETs using sacrificial amorphous silicon (a:Si) spacers to achieve low parasitic capacitance are fabricated. Radio frequency characterization of 73 devices is used to study the intrinsic and extrinsic capacitances. The total gate intrinsic parasitic capacitance of 0.55 fF/μm is achieved with an intrinsic gate capacitance of 0.39 μF/cm2. The various para
X-ray diffractometers primarily designed for surface X-ray diffraction are often used to measure the diffraction from powders, textured materials and fiber-texture samples in 2θ scans. Unlike in high-energy powder diffraction, only a fraction of the powder rings is typically measured, and the data consist of many detector images across the 2θ range. Such diffractometers typically scan in direction
A geyser elimination approach using recirculation methods is investigated in the present work, which is essential to guarantee the integrity of facilities. Both experimental and numerical methods are adopted in the investigation using LN2 as working fluids. A recirculation pipe is designed to eliminate geysers in a cryogenic vertical pipe. The performance of the recirculation method is comprehensi
A recent population-based, longitudinal study from Finland observed a dose-response association between smoking during pregnancy (SDP) and use of psychotropic medications in exposed children and young adults. However, this association may be confounded by unmeasured familial characteristics related to both SDP and offspring mental health. Consequently, we aim to investigate the effect of SDP by me
In Sweden, 2000 patients are diagnosed with rectal cancer annually. In 1995, the Swedish Rectal Cancer Registry (SRCR) was launched to supervise and assure the quality of the management of rectal cancer. Advances in the management of rectal cancer have reduced the local recurrence (LR) rate and improved survival. To improve the outcome further, identification of prognostic and predictive factors i
This paper reviews the evidence for an association between atypical subtrochanteric fractures and long-term bisphosphonate use. Clinical case reports/reviews and case-control studies report this association, but retrospective phase III trial analyses show no increased risk. Bisphosphonate use may be associated with atypical subtrochanteric fractures, but the case is yet unproven. A Working Group o
OBJECTIVE: The aim was to study effects on motor skills and self-esteem of an extension of the Swedish school subject Physical Education and Health (PEW and motor training during nine school years. DESIGN AND METHOD: An intervention group (n=161) had PEH and motor training five lessons (225 nun) and a matched control group (n=102) had regular PEH two lessons (90 min) per week. The method was hypot
Objective To assess the intervention fidelity and explore contextual factors affecting the process of implementing a mobile phone text messaging intervention in improving adherence to and retention in care among adolescents living with HIV, their families and their healthcare providers in southern Ethiopia. Design A convergent mixed-methods design guided by the process evaluation theoretical frame
Objective: To determine the relative contribution of each of the following aspects: demographics, physical function, and patient-reported outcome measures (PROMs), including both physical and psychological constructs, to return to sport (RTS) (any level) one-year post anterior cruciate ligament reconstruction (ACLR). Design: Cross-sectional cohort study. Methods: We included data for 143 participa
Aim: To investigate mothers' experience of infant massage. Design: This was an exploratory-descriptive qualitative study based on individual interviews. Methods: A qualitative interview study with an inductive approach was used according to the COREQ guidelines. The participants in the study were mothers (n = 11) residing in Sweden who received training in infant massage from the child health care
Study objectives: We examined and compared cross-sectional and longitudinal associations between self-reported sleep disturbances and various cognitive domains in five separate Nordic European longitudinal aging studies (baseline N = 5631, mean age = 77.7, mean follow-up = 4.16 years).Methods: Comparable sleep parameters across studies included reduced sleep duration/quality, insomnia symptoms (sl
Background: Obesity is a major public health concern associated with various health problems, including respiratory impairment. Bioelectrical impedance (BIA) is used in health screening to assess body fat. However, there is no consensus in healthcare on how body fat should be assessed in relation to lung function. In this study, we aimed to investigate how BIA in relation to waist circumference co
Background: Bladder cancer (BC) and Renal cell carcinoma (RCC) are the most common urogenital cancers among both sexes, with a yearly global incidence of around 500 000 each. Both BC and RCC have been linked to diabetes. Poor glycemic control (malglycemia) is a serious consequence of diabetes and a possible consequence of systemic treatments used in BC and RCC. The objective of this study was to i
