Published: July 2022

Background
The implementation of novel digital solutions within the National Health Service has historically been challenging. Since the start of the COVID-19 pandemic, there has been a greater push for digitization and for operating remote monitoring solutions. However, the implementation and widespread adoption of this type of innovation have been poorly studied.

Objective
We aim to investigate key stakeholder barriers and facilitators to implementing remote monitoring solutions to identify factors that could affect successful adoption.

Methods
A mixed methods approach will be implemented. Semistructured interviews will be conducted with high-level stakeholders from industry and academia and health care providers who have played an instrumental role in, and have prior experience with, implementing digital solutions, alongside the use of an adapted version of the Technology Acceptance Model questionnaire.

Results
Enrollment is currently underway, having started in February 2022. It is anticipated to end in July 2022, with data analysis scheduled to commence in August 2022.

Conclusions
The results of our study may highlight key barriers and facilitators to implementing digital remote monitoring solutions, thereby allowing for improved widespread adoption within the National Health Service in the future.

Labial frenectomy: current clinical practice of orthodontists in the United Kingdom
Authors: Ahn John HyunBaek , Newton Tim , Campbell Catherine 
Published: July 2022

ABSTRACT

Objectives
To obtain views of orthodontists in the United Kingdom on frenectomy in terms of its indications and timing and a recommended retention regimen after correction of median diastema.

Materials and Methods
A 14-item online questionnaire was sent to orthodontic specialists for completion. The questionnaire covered demographics and orthodontists' experience and views on frenectomy.

Results
Three hundred and fifty-three orthodontists with various background and experience responded to the survey. Three-quarters of respondents routinely performed a blanche test to aid diagnosis of the abnormal frenum; however, only 15% carried out radiographic investigation. Three-quarters of the orthodontists would consider frenectomy as a part of orthodontic treatment, and variation existed among the clinicians in terms of its timing. Frenectomy without orthodontic treatment was not preferred. There was much variation in the retention regimen after diastema closure regardless of frenectomy.

Conclusions
Complete consensus among the orthodontists was not obtained; however, some agreement was found regarding the development of a logical diagnosis and treatment approach. High-quality studies are required to produce national protocols or UK guidelines.

Authors: Hayder Abd Al-kaream Muhsin  
Published: July 2022

The main object of this study is to investigate the influence of column diameter and superficial gas velocity on liquid phase dispersion coefficients (axial and radial dispersion coefficients), mixing times, gas holdup, and bubble dynamics (bubble diameter and rise velocity). The liquid phase dispersion, gas holdup, and bubble dynamics (Db and Vb0) were measured for the air-water system in bubble columns of two different diameters,15 and 30 cm. The superficial gas velocity, Ug, was varied in the range 1-10 cm/s, spanning both the homogeneous and heterogeneous flow regimes. The height of liquid in the column was kept constant at 130 cm for the two column. Axial and radial dispersion coefficients and mixing times were measured at various axial and radial locations inside the columns (Z = 25, 75, 125 cm and r/R = 0, 0.45, 0.85), bubble dynamics were measured at three axial location (Z=25, 75, 125 cm). From the experimental data it was found that, the value of the radial dispersion coefficient (Dr,L) and axial dispersion coefficient (Dax,L), gas holdup, bubble diameter and bubble rise velocity, increase with increasing superficial gas velocity. The results emphasise the significant influence of the column diameter on the hydrodynamics. Gas holdup showed a decrease with increasing column diameter, while the radial dispersion coefficient (Dr,L), axial dispersion coefficient (Dax,L), bubble diameter and bubble rise velocity increased with increasing column diameter. A statistical analysis was performed to get a general correlations for the axial liquid dispersion coefficient as a function of the mixing time and dispersion height (Hd), this correlations are: Dax,L=0.15 H2d /θ0.3 for 30 cm column diameter and Dax,L=0.11 H2d /θ0.3 for 15 cm column diameter.

SWITCHING ANGLE OPTIMIZATION BASED GENETIC ALGORITHMS FOR HARMONIC REDUCTION IN THREE-PHASE PWM STRATEGY
Authors: Osama  Y. AL-Rawi  
Published: July 2022

In variable speed drive (VSD), it is desirable to reduce the harmonic effects, which causes current distortion and torque pulsation, besides, the harmonic power losses is an additional power losses that is introduced in the motor due to the presence of harmonic voltages.
However, the problem of the high total harmonic current distortion (THD) still exists specially at low and medium speeds by using sub-optimal pulse width modulation (PWM) strategy. In the past to generate optimized PWM, is done by defining a general PWM in terms of a set of switching angles. Which result in a set of nonlinear equations in terms of the unknown switching angles. These equations are nonlinear as well as transcendental in nature. There is no efficient method that can be applied to solve such equations. The practical method of solving these equations is a trial and error process. Taking all the factors into account, a numerical technique can be applied to solve these set of nonlinear equations, but with some limitations.
To overcome these limitations, Genetic algorithms (GAs) serves to search for optimal switching angles setting. In addition, the (THD) will be reduced, this lead to obtain the optimal PWM waveform and to simplify the practical implementation, and then improving the performance of the system output.
GAs were employed as a search and optimization engine. Normally the tuning of the switching angles is a trail and error problem.
In this paper, GAs provides a much simpler approach to off-line tuning of PWM switching angles than the rather complicated non-genetic optimization algorithms
PUNCHING SHEAR AND FLEXURAL STRENGTHS OF SELF COMPACTED CONCRETE NON-RECTANGULAR SHAPED FLAT PLATE SLABS
Authors: Ali H. Aziz  
Published: July 2022

This study is conducted to investigate experimentally the punching shear and flexural strengths of reinforced concrete flat plate slabs made with Non-Rectangular (triangular and trapezoidal) shaped. Four test self-compacting concrete slab groups were manufactured, each of which consisted of three slab specimens identical in size and shape but different in constituent’s properties. All slabs are simply supported along the all edges and subjected to single point load applied at the center of gravity of each slab.
Experimental results shows that the use of self compacting concrete improves the punching shear resistance and allows higher forces to be transferred through the slab-column connection. For slabs which were designed to fail in punching shear, the ultimate capacity of the tested specimens increased by (7%) to (20%) when the shape of slab specimens changed from triangular to trapezoidal. In contrast of slabs which were designed to fail in flexure, the ultimate capacity of the tested specimens increased from (16%) to (58%) when the shape of slab specimens changed from triangular to trapezoidal.
The cracking load depends essentially on concrete strength and not on slab configuration, but, the ultimate capacity depends on both, concrete strength and shape of slab.
ESTIMATION OF (Nγ) FOR STRIP AND CIRCULAR FOOTINGS USING THE METHOD OF CHARACTERISTICS
Authors: Lamyaa Najah Snodi  
Published: July 2022

By using the method of characteristics (commonly referred to as the slip line method), the values of the bearing capacity factor Nγ were computed for rigid surface strip and circular footings with smooth and rough bases. The analyses of bearing capacity for vertically loaded footings using the method of characteristics have been implemented in the publicly available computer program ABC, then Nγ –values were calculated theoretically. The supporting soil is modeled as a frictional Mohr – Coulomb material. For both footings, the value of the bearing capacity factor Nγ was found to increases significantly with an increase in the angle of internal frictionf. When friction angle of soil f ≤25°, the computed values of Nγ for circular footing were found to smaller than those for strip footing and for larger values of f, the magnitude of Nγ for circular footing were greater than those for strip footing for both smooth and rough base of footings. On the other hand, the magnitude of Nγ for rough footings was seen be higher than for a footings with smooth base. The obtained results were compared with those available in the literature, and reasonable agreements were observed.

Era reformasi telah merubah paradigma negara dalam melihat desa khususnya desa yang berbasis adat. Hal ini terlihat dalam melihat bagaimana relasi antara pemerintah desa dan adat, serta relasi antara pemerintah desa dan masyarakat khususnya dalam hukum-hukum adat dan pemerintah dalam hal ini negara. Pada saat inilah terbangun ruang dialog, kompromi atau negosiasi bahkan seringkali menimbulkan resistensi oleh salah satu pihak. Situasi ini kemudian membentuk sebuah konstruk sosial baru dalam bentuk perebutan ruang, perdebatan serta ruang-ruang pencarian identitas-identitas masing-masing. Akhirnya, komunitas adat Ammatoa sebagai komunitas local terlihat berada pada posisi tersubordinasi oleh negara. Oleh karena itu, sebagai jalan satu-satunya mereka selalu mencari ruang-ruang negosiasi atau bahkan kompromi dalam berhadapan dengan negara demi sebuah eksistensi untuk terus terjaga.
Research on the mining of ideological and political knowledge elements in college courses based on the combination of LDA model and Apriori algorithm
Authors: Wang Long 
Published: July 2022

Abstract
In recent years, mapping of knowledge domain and political knowledge has developed rapidly and gradually penetrated into many practical applications. The construction of an ideological and political knowledge framework for colleges has become one of the important applications. Therefore, commencing with the theory of mapping of knowledge domain, and aiming at resolving the difficulty involved in effectively extracting and analysing ideological and political knowledge, a mining method for ideological and political knowledge elements is constructed in this paper, based on LDA model and Apriori algorithm. By setting a three-dimensional matrix of keywords and association rules, an algorithm for mining of ideological and political knowledge elements is proposed, where LDA model is used to acquire ideological and political subject words, and Apriori algorithm is used to discover tacit ideological and political knowledge. It is helpful to solve the problem of excavation and presentation of ideological and political elements in college curriculum, serve the ideological and political construction of curriculum, which is of great significance to dredge students’ learning paths and reduce learners’ learning cost.
