A study of Class III treatment: orthodontic camouflage vs orthognathic surgery
Authors: Georgalis Katherine , Woods Michael G. 
Published: September 2021

Abstract

Aim
To evaluate the differences in pretreatment and post-treatment characteristics of Class III patients treated with orthodontic camouflage or orthognathic surgery, and to compare the range of skeletal, dental and soft tissue changes that are likely to occur with treatment, with particular reference to the influence of extractions on the resultant incisor angulations.

Method
Pretreatment and post-treatment cephalograms of 31 Class III orthodontically-camouflaged patients and 36 Class III surgical patients (without genioplasty) were obtained from one specialist practice. From the surgical group, 26 pre-surgical lateral cephalograms were also obtained. Inclusion criteria for the two groups were at least three of the following: (1) an ANB angle of 1 degree or less, (2) a Wits appraisal less than -4 mm, (3) an incisal overjet ≤0 mm, and (4) a Class III molar relationship. All lateral cephalograms were traced and digitised and a number of skeletal, dental and soft tissue variables were measured. The camouflage and surgical groups were also divided into premolar extraction and non-extraction subgroups to allow for a specific analysis of extraction effects.

Results
Before treatment, the surgical group demonstrated, on average, a more severe skeletal discrepancy and increased dental compensations, compared with the orthodontically camouflaged group. After treatment, the mean SNA angle was greater, the ANB angle was more positive, the Wits appraisal was closer to ideal and the lower incisors were less retroclined in the surgery group. There was a small mean reduction in horizontal chin projection in the surgery group compared with a small increase in the camouflage group. The mentolabial fold and the lower lip curve were deeper, on average, and the lips less retrusive after surgery. There was a mean increase in upper incisor proclination during treatment in both the surgical and camouflage groups with a greater increase in the camouflage group. There was a significant reduction in upper incisor proclination and a subsequent greater increase in the ANB angle associated with upper premolar extractions in the surgical group compared with the non-extraction group. Lower premolar extractions in the camouflage group resulted only in a deeper mentolabial fold compared with those treated without lower extractions.

Conclusions
Class III patients selected for surgical treatment are likely to have more severe pretreatment dental and skeletal discrepancies than those selected for camouflage treatment. Surgical treatment is associated with significant decompensation of the lower incisors but, ultimately, not the upper incisors. Class III patients treated with either camouflage or surgery treatment are likely to finish with slightly proclined upper incisors. Generally, surgical treatment results in greater skeletal change, involving normalisation of the skeletal base relationship, a reduction in chin prominence, fuller lips, and a more favourable lip and chin contour.

Authors: Bakhadher Waleed , Talic Nabeel , Al Hezaimi Khalid 
Published: September 2021

Abstract

Objectives
The aim of the present study was to assess and compare the shear bond strength (SBS) of metal pre-coated orthodontic brackets bonded to fluorotic and non-fluorotic teeth treated with three different etching techniques. A second aim was to determine the volume of adhesive remaining on the tooth at debond using micro-computed tomography (μCT).

Methods
Ninety extracted premolars were selected to include 45 fluorotic (test group) and 45 non-fluorotic (control group) teeth. Each group was divided into three subgroups of 15 each, which were treated as follows: 1) micro-etched; 2) acid-etched; and 3) both micro-etched and acid-etched. A bonding agent was applied to the prepared surfaces; pre-coated and light-cured brackets were attached to all teeth. An Instron universal testing machine was used to record the debonding force. Specimens were then scanned using a microCT to evaluate the amount of adhesive remaining on the teeth. The significance of the statistical tests was pre-determined at p < 0.05.

Results
Two-way ANOVA showed that fluorosis of teeth had no influence on the SBS (p = 0.165) whereas the volume of adhesive remnants was significantly higher in the control group compared with the test group (p < 0.001).

Conclusions
Fluorosis had no influence on the SBS of brackets, whereas it had a negative influence on retaining adhesives onto the tooth surfaces.
Density matrices in integrable face models
Authors: Frahm Holger , Westerfeld Daniel 
Published: September 2021

Using the properties of the local Boltzmann weights of integrable
interaction-round-a-face (IRF or face) models we express local operators
in terms of generalized transfer matrices. This allows for the
derivation of discrete functional equations for the reduced density
matrices in inhomogeneous generalizations of these models. We apply
these equations to study the density matrices for IRF models of various
solid-on-solid type and quantum chains of non-Abelian
\mathbold{su(2)_3}𝐬𝐮(2)3
or Fibonacci anyons. Similar as in the six vertex model we find that
reduced density matrices for a sequence of consecutive sites can be
‘factorized’, i.e. expressed in terms of nearest-neighbour correlators
with coefficients which are independent of the model parameters.
Explicit expressions are provided for correlation functions on up to
three neighbouring sites.

Imperfect competition in social and labour relations has no homogeneous effect on regional labour markets. There is a regional segmentation of the domestic labor market under the influence of imperfect competition. Government measures and measures to regulate the domestic labour market have different effects on regional labour markets. In this regard, the weakening of imperfect competition in social and labour relations is seen through the strengthening of the role of the regional labour policy of the population.

Features of brittle fracture of steels at low temperatures
Authors: Гущин С.Н. , Поярков М.С. 
Published: September 2021

В статье рассмотрены особенности хрупкого разрушения сталей в условиях низких температур. Разрушение стальных конструкций чаще всего начинается от концентраторов напряжения (производственные дефекты, сварные швы и т.д.) В результате понижения температуры влияние этих факторов резко усиливается. В этом случае требуется применение металла, способного к пластической деформации при низких температурах, поскольку хрупкое разрушение по своим последствиям значительно опаснее, чем пластичное. Пластическая деформация осуществляется за счет перемещения дислокаций, которые являются проявлением несовершенства кристаллический решетки. Под влиянием напряжений при отсутствии препятствий дислокации свободно перемещаются в решетке металла. Понижение температуры приводит к тому, что возрастающий предел текучести достигает значений хрупкой прочности. Существенное влияние на хладостойкость стали оказывают примеси. Влияние примесей связано в первую очередь с загрязнением границ зерен сплавов и уменьшением сил сцепления на плоскостях спайности. Кроме этого, границы зерен характеризуются значительными нарушениями кристаллического строения и являются участками скопления дефектов структуры и включений.
The article deals with the features of brittle fracture of steels at low temperatures. The destruction of steel structures most often begins from stress concentrators (manufacturing defects, welds, etc.) As a result of a decrease in temperature, the influence of these factors increases dramatically. In this case, the use of a metal capable of plastic deformation at low temperatures is required, since brittle destruction is much more dangerous in its consequences than plastic. Plastic deformation is carried out due to the displacement of dislocations, which are a manifestation of the imperfection of the crystal lattice. Under the influence of stresses in the absence of obstacles, dislocations move freely in the metal lattice. A decrease in temperature leads to the fact that the increasing yield strength reaches the values of brittle strength. Impurities have a significant effect on the cold resistance of steel. The influence of impurities is primarily associated with contamination of the grain boundaries of alloys and a decrease in the adhesion forces on the cleavage planes. In addition, the grain boundaries are characterized by significant violations of the crystal structure and are areas of accumulation of structural defects and inclusions.

Human Resource Procurement in Pesantren? Insight from Pesantren Sirojuth Tholibin
Authors: Sholihah Baqiyatush 
Published: September 2021

Human resource procurement is one of the essential stages of organizational decision-making. The scope of procurement consists of planning, recruitment, selection, placement, and orientation of new personnel. Human resources studied in this research are situated in Pesantren comprising of the committee or board; teachers of kitab kuning (classical Arabic Islamic textbook) either with sorogan or bandongan methods; teachers of reciting and memorizing Al-Qur’an; persons in charge of media such as website, Facebook, Twitter, Instagram, YouTube, magazines, and newsletters of Sirojuth Tholibin both. Sirojuth Tholibin commonly used a bottom-up approach in human resources planning. As a part of the planning process, The institution usually combines unstructured interview and observation methods in job analysis. In recruitment and selection, Sirojuth Tholibin pays more attention to behavioral competencies over technical competencies. Recruitment of committee and teachers usually carried out through the employee referral method. Those recruited and selected are recommendations from previous administrators who understand the background of potential candidates. The placement of new human resources is made based on their respective competencies. Orientation is the responsibility of each department, and the duration is according to the speed of each new individual in capturing new knowledge related to their jobs. The weakness of human resources procurement in Sirojuth Tholibin has no formal written job description and job specification. There is also a lack of management information systems of human resource procurement.

Authors: Li Jun , Liu Chunye , Tang Li 
Published: September 2021

Abstract
Regional water demand is an important basic data for regional engineering planning, design and management. Making full use of multi-source data and prior knowledge to quickly and economically obtain high-precision regional water demand is of great significance to the optimal allocation of regional water resources. In order to accurately predict the regional water demand, this study took Yulin City as a research area to predict the water demand of the city from 2017 to 2019. Aiming at the oscillating characteristics of the regional water demand sequence and the over-fitting problem of traditional prediction models, this study proposed the non-dominated sorting genetic algorithm II-fractional order reverse accumulative grey model (NSGAII-FORAGM). The regional water demand oscillation sequence was transformed into a monotonically decreasing non-negative sequence. Based on the transformation sequence, an optimization model was constructed according to the two objective functions of ‘maximum (or minimum) order’ and ‘best fit to historical data’, and the NSGAII method was adopted to solve the model. The three model structures of ‘fractional order’, ‘reverse accumulation’ and ‘obtaining order through multi-objective optimization model ‘ were tested based on the water use sequence of the three sectors (industry, tertiary industry and domestic) in Yulin City, and the performance of the method is compared with NSGAII-IORAGM, NSGAII-FOFAGM and SOGA-FORAGM. The results showed that the average relative error of the model established in this study for the simulation of industry, tertiary industry (the tertiary industry is a technical name for the service sector of the economy, which encompasses a wide range of businesses), and domestic was 15.54%, 11.20%, 9.98% respectively. The average relative error of the model established in this study for the prediction of industry, tertiary industry and domestic was 9.46%, 7.9%, and 1.8%, respectively. For the simulation of water demand sequences in three sections, the simulation average relative errors of the other three models were not absolutely dominant except for the SOGA-FORAGM model. The average relative predicted error by the model in this study was the smallest (the relative errors of the three sequence predictions for industry, tertiary industry and domestic were lower than the relative errors of the optimal results of the comparison model, which were 0.97%, 0.72% and 4.5%, respectively), indicating that the model had certain applicability for the water demand prediction of various sectors (industry, tertiary industry and domestic) in the region compared with other models, and can improve the accuracy of the prediction results.

Authors: Iltchenco Janaina , Peruzzo Vanessa , Eva Magrini Flaviane , Marconatto Letícia , Paula Torres Ana , Luiz Beal Lademir , Paesi Suelen 
Published: September 2021

Abstract
The vinasse is a residue of ethanol production with the potential for methane production, requiring an allochthonous inoculum. Several microorganisms act in the different phases of anaerobic digestion, and the identification of these microbial communities is essential to optimize the process. The characterization of the microbiota involved in the biodigestion of vinasse was observed in the initial stage (IS), at the peak of methane production (MS) and the end of the process (FS) of the best performance assay by high-throughput sequencing. The highest methane production was 0.78 mmolCH4.gVS.h−1 at 243.7 h in the substrate/inoculum ratio of 1.7, with consumption partial of acetic, propionic and isobutyric acids and an 82% reduction of chemical oxygen demand. High microbial diversity was found. The genera Clostridium, Acinetobacter, Candidatus Cloacamonas, Bacteroides, Syntrophomonas, Kosmotoga, the family Porphyromonadaceae and the class Bacteroidia were the most abundant in the maximum methane production. Methane production was driven by Methanobacterium and Methanosaeta, suggesting the metabolic pathways used were hydrogenotrophic and acetoclastic.
Production and modification of hydrochar from anaerobically digested cattail for adsorbing ammonium and phosphorous in wastewater
Authors: Ghimire Sanjaya , Wang Lijun , Zhang Bo , Li Xin , Shahbazi Abolghasem 
Published: September 2021

AbstractWater contamination by nitrogen and phosphorus ions has a direct consequence of eutrophication to the ecosystem. The objective of this study is to investigate the production of hydrochars by acetic acid or sodium hydroxide assisted hydrothermal carbonization (HTC), various activation methods, and the potential of hydrochar as an adsorbent to remove NH4+-N and PO43−-P from wastewater. The results showed that acetic acid or sodium hydroxide assisted HTC and activation with magnesium chloride or air could improve the surface properties of hydrochar. Acetic acid modification generated extensive oxygenated functional groups, while sodium hydroxide modification produced hydrochar with a high N/C ratio and surface aromaticity. Treating hydrochar with magnesium chloride could impregnate nano-magnesium particles on the hydrochar, thereby improving the ability to remove N and P. Air activation of hydrochar resulted in more oxygen containing functional groups. The NH4+-N and PO43−-P adsorption capacities of these hydrochars ranged from 92.6 to 122.4mg/g and 1.6 to 15.8mg/g, respectively. The adsorption capacity of hydrochars in swine wastewater is similar to the results of artificial wastewater. The results suggested that Mg-nanoparticle dispersion and oxygen-containing functional groups played a major role in adsorption than ion exchange and physisorption.

Published: September 2021

:
Candida albicans is one of the main agents responsible for opportunistic pathogenic infections. The
progressive emergence of fungal resistance to conventional antibiotics and its side effects, as well as treatment
costs, are considered major limitations for antifungal drugs. It has drawn scientists' attention to the search for
potential substitution and reliable therapeutic alternatives for the antifungal compounds from sources like medicinal
plants, which contain numerous bioactive compounds such as essential oils. Essential oils (EO), apart
from having lower toxicity and better biodegradability, are eco-friendly in nature as compared with conventional
antibiotics. Furthermore, extracted essential oils have been reported to possess potent antimicrobial, antiinflammatory,
and antioxidant properties that nominate them as promising natural candidates to combat numerous
fungal ailments. Thus, the determination of antifungal efficacy of essential oil-bearing plants on Candida
spp. will provide miscellaneous knowledge for future clinical studies that are required for the development of
new formulations as alternative therapeutic agents to control the growth of Candida species. Therefore, this review
summarizes the gist of major essential oils that have been investigated for their anti- Candida potential
with some recommendations for further study.
Frequency of Cardiac Arrhythmias in Children with Cardiological Consulting and Containing Electrocardiogram
Authors: Nezami Alireza , Heidari Ghobad , Tarhani Fariba , Oliaee Fatemeh 
Published: September 2021

Background:
Heart diseases are the leading causes of mortality and Congenital Heart
Disease (CHD) is the most common birth defect reported worldwide.

Objective:
The aim of this study was to evaluate the incidence of arrhythmias and CHD and the association
between the two, among infants and children reported to our center.

Methods:
This cross-sectional study included infants and children who were referred to Shahid Madani
Hospital, Khorramabad. Electrocardiogram (ECG) was performed in these children to determine
the type of arrhythmia and records were used to obtain demographic data and the data regarding
CHD.

Results :
Of 200 children enrolled in the study, 10 children had arrhythmias, 12 had tachycardia, 5
had bradycardia, and 31 had congenital disease. Among children with arrhythmias, 1 had atrial fibrillation,
4 patients had paroxysmal supraventricular tachycardia, 1 person had right bundle branch
block, 1 had ventricular tachycardia, 2 had premature ventricular contractions and 1 had junctional
ectopic tachycardia. Of the 31 children with CHD, 9 patients were presented with small ventricular
septal defect, 4 children had patent foramen ovale, 2 had pulmonary stenosis and 1 of the children
had tetralogy of fallout, arterial and ventricular septal defects and transposition of greater arteries,
respectively.

Conclusion:
We reported a positive correlation between the arrhythmias and CHD. A larger number
of studies collecting focusing on different age groups are therefore required to verify our findings.
