Acute uterine inversion – A complication revisited; a case series and review of literature
Authors: Kaur Amanjot , Singh Beant 
Published: June 2022

Abstract

Objectives
The objective of this case series is to discuss the various presentations of acute uterine inversion and to discuss how these varied presentations can cause a diagnostic confusion. Differences in acute uterine inversion following a vaginal delivery and a cesarean section are also discussed along with the management of acute uterine inversion, emphasizing the need for a rapid diagnosis and management.

Case presentation
Three such cases of acute uterine inversion – two after vaginal delivery (one second-degree inversion and one third degree inversion) and one during cesarean section have been discussed along with their management.

Conclusions
Uterine inversion is a potentially life-threatening complication which can be prevented by active and careful management of third stage of labor and avoiding cord traction prior to development of the signs of placental separation. Early stages of uterine inversion may be confused with a prolapsed fibroid or a cervical polyp. Prompt management can avert maternal mortality and morbidity.
Extreme fetal macrosomia at 42 gestational weeks: a case report and literature review
Authors: Kummer Julia , Callister Yvonne , Jebens Anja , Mihajlov Valentin , Pech Luisa Maria , Hellmeyer Lars 
Published: June 2022

Abstract

Objectives
Fetal macrosomia is a term to describe excessive fetal birth weight. Fetal macrosomia is strongly associated with adverse obstetrical outcome.

Case presentation
We report a rare case of excessive neonatal weight in a medically unsupervised pregnancy and give a literature review on this significant subject. A 38 year-old woman (Gravida 8 Para 7) presented herself at 42 2/7 weeks of gestation at the labor ward. The pregnancy had not been supervised medically. Labor induction was initiated. Due to failure to progress and suspicion of a disproportion of the fetal head and maternal pelvis an urgent caesarean section was performed. A morbidly macrosomic male infant was delivered (birth weight: 6,760 g [>99. percentile], length: 60 cm [>99. percentile]).

Conclusions
The morbidity for infants and women increases with a birth weight exceeding 4,500 g. Gestational diabetes mellitus, a high pre-pregnancy body mass index and excessive gestational weight gain have been independently associated as risk factors. The increase in pregnancies complicated by maternal obesity and gestational diabetes emphasizes the necessity of evidence-based clinical interventions to prevent or reduce these diseases. If prenatal care is not frequented by mothers-to-be there are no options open for obstetricians to detect fetal macrosomia and to intervene.

Published: June 2022

Abstract

Objectives
To describe the importance of comprehensive assessment to determine the underlying diagnosis and the role of physiological pulmonary measurements in the management of congenital bilateral eventration of the diaphragm.

Case presentation
A female infant born at 34 weeks gestation required intubation and ventilation at birth. Chest radiographical imaging revealed bilateral density to the bases of both lung fields with raised hemi-diaphragms. Ultrasound imaging showed focal diaphragmatic eventration with bulging of the dome of the liver into the right and left hemithoraces. Assessment of the electrical activity of the diaphragm during a spontaneous breathing trial demonstrated a mean amplitude consistent with that of ventilated infants of the same gestational age with intact diaphragms. Hence she was extubated which was successful. Chest radiographic thoracic area measured post extubation was 1,654 mm2, equivalent to that of a term infant with severe congenital diaphragmatic hernia. As the electrical activity of the diaphragm was normal this suggests replacement of the diaphragmatic muscle tissue with fibrous bands was likely to be only partial, and hence why extubation was successful. She had other abnormalities presenting in the neonatal period including dermal melancytosis, central hypotonia, hyperinsulinism and poor feeding. The infant underwent extensive investigation which revealed a KMT2D gene mutation associated with Kabuki syndrome.

Conclusions
Physiological pulmonary measurements may add clinical management in bilateratal diaphragmatic eventration.

Authors: Fankhouser Russell W. , Murrell Derek E. , Anane Yaa Y. , Hurley David L. , Mamudu Hadii M. , Harirforoosh Sam 
Published: June 2022

Abstract

Objectives
This study sought to identify potential pharmacogenetic associations of selected enzymes and transporters with type 2 diabetes (T2D). In addition, pharmacogenomic profiles, concentrations of asymmetric dimethylarginine (ADMA) or kidney injury molecule-1 (KIM-1), and several covariates were investigated.

Methods
Whole blood was collected from 63 patients, with 32 individuals with T2D. A pharmacogenomic panel was used to assay genetic profiles, and biomarker ELISAs were run to determine subject concentrations of ADMA and KIM-1. Additive genetic modeling with multiple linear and logistic regressions were performed to discover potential SNPs-outcome associations using PLINK.

Results
Ten SNPs were found to be significant (p<0.05) depending on the inclusion or exclusion of covariates. Of these, four were found in association with the presence of T2D, rs2231142, rs1801280, rs1799929, and rs1801265 depending on covariate inclusion or exclusion. Regarding ADMA, one SNP was found to be significant without covariates, rs1048943. Five SNPs were identified in association with KIM-1 and T2D in the presence of covariates, rs12208357, rs34059508, rs1058930, rs1902023, and rs3745274. Biomarker concentrations were not significantly different in the presence of T2D.

Conclusions
This exploratory study found several SNPs related to T2D; further research is required to validate and understand these relationships.
Hydrodesulfurization of 4,6–Dimethyldibenzothiophene on NiMoP/γ–Al2O3 catalyst under reactive distillation conditions in a micro trickle bed reactor: solvent and temperature effect
Authors: García-Martínez Julio Cesar , Chávez-Esquivel Gerardo , Colín-Luna José Antonio , de los Reyes-Heredia José Antonio 
Published: June 2022

Abstract
In this work, the influence of pressure and temperature experimentally applied on reactive distillation (RD) under lower conditions than conventional hydrotreating (HDT) processes, the hydrodesulfurization (HDS) reaction of 4,6–dimethyldibenzothiophene (4,6–DMDBT) molecule and the experimental performance of a down-flow micro trickle bed reactor (micro-TBR) with n–dodecane and decalin were studied. Thermodynamic analyses to evaluate hydrogen solubility in liquid hydrocarbons and evaporation for n–dodecane and decalin as lineal and cyclic representative solvents, respectively, were considered. It was possible to define experimental conditions, producing a small deviation of the plug flow model (PFM) and diminished the gas–liquid (G–L) mass transfer limitation as determined from a reactor model at 2.5 MPa. The axial dispersion model (ADM) and PFM models adjust the experimental data at 2.5 MPa operational pressure and the 4,6–DMDBT conversion obtained was ca. 20–50% using n–dodecane; 1.5 times higher when decalin was using. This behavior was due to the liquid hydrogen fraction of n–dodecane was two times higher than for decalin for all operational pressures. In this sense, the use of n–dodecane as a solvent decreased the mass transfer resistance at the G–L and liquid–solid (L–S) interphases. The internal mass transfer resistance in the G–L interphase not only depends on the diffusivity of the solvent, but it also depends on both, the temperature and hydrogen pressure, finding that the RD conditions with n–dodecane are viable in the treatment of sterically impaired molecules in HDS processes.

Abstract
In this note we consider a parabolic evolution equation in a polygonal space-time cylinder. We show, that the elliptic part is given by a m-accretive mapping from L

q
(Ω) → L

q
(Ω). Therefore we can apply the theory of nonlinear semigroups in Banach spaces in order to get regularity results in time and space.
The second part of the paper deals with the numerical solution of the problem. It is dedicated to the application of the space-time discontinuous Galerkin method (STDGM). It means that both in space as well as in time discontinuous piecewise polynomial approximations of the solution are used. We concentrate to the theoretical analysis of the error estimation.
Updating risk model for SGTR accident based on success criteria analysis
Authors: Mohammadnia Meisam , Hoseyni Seyed Mohsen , Karimi Kaveh 
Published: June 2022

Abstract
Success criteria analysis plays a key role in the development of realistic probabilistic safety/risk assessment (PSA/PRA) model because it provides supporting information regarding the response of complex nuclear power plant systems to different accident conditions. The current paper performs plant specific success criteria analysis for steam generator tube rupture (SGTR) accident in a typical pressurized water reactor (PWR) and demonstrates implementation of the obtained best estimate results on a risk model which has been initially developed based on expert judgment and general plant design data. The modifications on the risk model include configuration of the safety systems as well as the event tree structure. The updated PSA model shows 50% reduction in the plant core damage frequency (CDF) in comparison to the base case risk model. This highlights the importance of success criteria analysis for the development of a realistic PSA model in risk informed applications.

-laplacian along a sequence of approximate maximum points, we obtain monotonicity of positive solutions in the whole space via the sliding method. In order to solve the difficulties caused by the gradient term, we introduce some new techniques which may also be applied to investigate the qualitative properties of solutions for many problems with gradient terms. Our results are extensions of Berestycki and Nirenberg [Monotonicity, symmetry and antisymmetry of solutions of semilinear elliptic equations, J. Geom. Phys. 5 (1988), 237–275] and Wu and Chen [The sliding methods for the fractional p-Laplacian, Adv. Math. 361 (2020), 106933].
Smear character recognition method of side-end power meter based on PCA image enhancement
Authors: Luo Peng , Hu Xuekai , Zhao Yuhao , Jiang Yi , Lu Fanglin , Liang Jifeng , Xu Liang 
Published: June 2022

Abstract
Since it is difficult for manual recording to track the rapid change of indication of the power meter, the power meter images are collected by the camera and automatically recognized and recorded to effectively overcome the disadvantages of manual recording. However, the complex scene lighting environment and smearing character shadows make it difficult to transfer captured images directly to convolutional neural networks for character recognition. A smear character recognition method of side-end power meter under complex lighting conditions is proposed in this article. First, the uneven illumination image enhancement algorithm is studied. Through the estimation of the illumination component of the image, the fusion weight is calculated by the principal component analysis for multiscale fusion, and the up-sampling and down-sampling are adopted to reduce the calculation of the algorithm and achieve the rapid image enhancement. A convolution neural network framework based on deep learning is proposed to realize the segmentation of smear characters, and the final segmented individual characters are fed into a network to identify the meter readings. The experimental results show that the proposed smear character recognition method has fast recognition speed, and the recognition rate of samples with the smear character and complex illumination reaches 99.8%, which meets the requirements of power meter character recognition and is better than other algorithms.

Authors: Yao Chengli , Ding Aimin , Li Hongying , Wei Yanxin 
Published: June 2022

Abstract
The traditional measurement methods of luminescent materials have some problems, such as low accuracy and large amount of calculation. Therefore, a new measurement method is proposed in this article. Taking molecular capture as the core, the molecular force field is established. According to the first law of hohber_Kong’s molecules captures molecular dynamics, it extracts dynamic simulation data information and takes this as the input to establish the Markov data analysis model. The molecular dynamics data were input, and the multi-index method was used to describe the characteristics of metal complex luminescent materials. According to the external shape of the material and the tightness of molecular blocks, the dynamic observation index of the current complex can be obtained to determine the characteristics of luminescent materials. The experimental data show that the method in this article has higher accuracy, lower amount of calculation and good overall error adjustment effect. It can effectively determine the characteristics of complex luminescent materials.

Published: June 2022

Abstract
The present study was developed to reinforce a thermoplastic matrix with carbonaceous material to improve its thermal and mechanical properties. Composite materials formed from the homogenization of polylactic acid (PLA) and reduced graphitic oxide (RGO) were synthesized and characterized, reinforcement of the polymer’s thermomechanical properties and the adequate homogeneity ratio in the dispersion of the composite material were studied. Graphitic oxide (GO) was synthesized by the modified Hummers method, followed by thermal exfoliation. The chemical composition and the structure of RGO were studied by infrared (FT-IR) and Raman spectroscopies, respectively. PLA composites with different RGO contents (2 and 3% by weight) were prepared and compared in terms of distribution of RGO in the matrix and morphology, using scanning electron microscopy. The thermal stability of the composites was determined through thermogravimetric analysis. Torque of the different composites was measured, which increased at 21%; the tensile test showed an improvement in the mechanical parameters of the composites because the RGO favors the rigidity of the composite. In addition, the oxygenated functional groups present in the RGO allowed a more significant interaction with the PLA matrix, which results in an effective reinforcement of the mechanical properties of the composite material.

PERANAN AGEN SOSIALISASI IBU BAPA TERHADAP PENGETAHUAN POLITIK MAHASISWA MELAYU DI UNIVERSITI AWAM
Authors: Mazli Mamat  , Ramli Rahimi 
Published: June 2022

Abstract - The voting age restriction has been lowered to 18 years old, and the removal of Section 15(2)(c) of the AUKU has made it the country's responsibility to prepare young people to become mature voters. Some of these groups are made up of university students. The socialization process of students who are knowledgeable as voters in elections is closely tied to their socialization process. As a result, the purpose of this study is to analyze students' political knowledge levels as well as the role of parents as the earliest and most organized political socialization agents in influencing students' political knowledge. Malay students from four public universities in the Klang Valley were asked to participate in this study. The research uses a quantitative approach, and the information was gathered through questionnaires collected during a field survey. The study's sample included 441 Malay students who were chosen using stratified and simple sampling methods. The study's findings revealed that, despite their high level of political knowledge, the students' political information was not received directly from their parents' agents. As a result, these students learned knowledge from other socialization agents, particularly in relation to politics, but the values and beliefs that parents socialize remain their consideration and reference, as parents are more stable socialization agents than other socialization agents.

Abstrak - Had umur minimum kelayakan pengundi diturunkan kepada usia 18 tahun dan pemansuhan Seksyen 15(2)(c) AUKU telah menjadi tanggungjawab besar negara untuk mempersiapkan golongan muda menjadi pengundi yang matang. Sebahagian mereka ini terdiri dalam kalangan mahasiswa universiti. Siap siaga mahasiswa yang berpengetahuan sebagai pengundi dalam pilihan raya berkait rapat dengan proses sosialisasi yang dilalui oleh mereka. Oleh itu, makalah ini bertujuan untuk membincangkan tahap pengetahuan mahasiswa serta peranan ibu bapa sebagai agen sosialisasi politik terawal dan berstruktur dalam menyumbang kepada pengetahuan politik mahasiswa. Responden yang terlibat dalam kajian ini ialah mahasiswa berbangsa Melayu di empat buah Universiti Awam terpilih sekitar Lembah Klang. Kajian ini menggunakan pendekatan kuantitatif dan data kajian diperoleh melalui borang soal selidik yang dikumpul semasa tinjauan dilakukan di lapangan. Sampel kajian terdiri daripada 441 orang responden mahasisiwa Melayu yang dipilih berdasarkan pensampelan berstrata dan persampelan mudah. Hasil kajian mendapati pengetahuan politik responden mahasiswa bukanlah diperolehi daripada agen ibu bapa secara langsung walaupun mereka mempunyai pengetahuan yang tinggi tentang aspek politik. Oleh itu, mahasiswa ini mendapat pengetahuan khususnya berkaitan politik adalah daripada agen sosialisasi lain namun aspek nilai dan kepercayaan yang disosialisasikan oleh ibu bapa tetap menjadi pertimbangan dan rujukan mereka kerana ibu bapa merupakan agen sosialisasi yang lebih stabil berbanding agen sosialisasi lain.

Authors: Shamsuddin Solehah , Abdul Karim Asar , Omardin Mohammad Affendy 
Published: June 2022

Abstract - The term Islāmic marriage counseling among the Muslim community in Malaysia was first introduced along with the implementation of Islamic family law in the early 80’s. Marriage counseling at State Islamic Religious Office [Pejabat Agama Islām Negeri (PAIN)] in Malaysia is a thing that has been going on for a long time. Yet to date, there is still no standard guidelines for the marriage counseling at PAIN. Each Islāmic marriage counselor has his/ her own interpretation about the guidelines that need to be practiced. Therefore, this study has come up with some suggestions of the guidelines needed to be practiced in the process of Islāmic marriage counseling to ensure it achieves the stated desired objectives.

Abstrak - Istilah runding-cara di kalangan masyarakat Islam di Malaysia mula diperkenalkan dengan perlaksanaan undang-undang keluarga Islam di awal tahun 80an. Runding-cara perkahwinan di Pejabat Agama Islām Negeri (PAIN) adalah suatu perkara yang telah lama dijalankan. Namun sehingga kini, masih tidak terdapat garis panduan yang seragam di setiap PAIN masing-masing. Para perunding, masing-masing mempunyai interpretasi tersendiri tentang garis panduan yang perlu diamalkan. Oleh itu, kajian ini telah mendatangkan beberapa cadangan garis panduan yang perlu diamalkan dalam proses runding-cara perkahwinan bagi memastikan runding-cara tersebut mencapai objektif yang dikehendaki.
