Published: November 2021

Abstract
The main aim of this study is to examine the effect of incorporating limestone fines (LF) on chemical shrinkage of pastes and mortars. For this purpose, five paste and five mortar mixes were prepared with 0, 5, 10, 15 and 20% (by weight) LF as replacement of cement. The water to binder ratio (w/b) was 0.45 for all mixes. The sand to binder (s/b) ratio in the mortar mixes was 2. Testing included chemical shrinkage, compressive strength, density and ultrasonic-pulse velocity (UPV). Chemical shrinkage was tested each hour for the first 24 hrs, and thereafter each 2 days until a total period of 90 days. Furthermore, compressive strength and UPV tests were conducted at 1 day, 7, 28 and 90 days of curing. The results show that the long-term chemical shrinkage of pastes was found to increase with the increase in LF content up to 15%. Beyond this level of replacement, the chemical shrinkage started to decrease. However, the chemical shrinkage for mortars increased with the increase in LF content up to 10% LF and a decrease was observed beyond this level. It was also noticed that compressive strength for pastes and mortars attained the highest value for mixes containing 10 and 15% LF. The trend in the UPV results is somewhat similar to those of strength. Density for pastes and mortars increased up to 15% LF followed by a decrease at 20 % replacement level. Correlations between the various properties were conducted. It was found that an increase in chemical shrinkage led to an increase in compressive strength.
A search for a stochastic archetype of quantum probability
Authors: Jenkins Tim C 
Published: November 2021

Abstract
Superposed wavefunctions in quantum mechanics lead to a squared amplitude that introduces interference into a probability density, which has long been a puzzle because interference between probability densities exists nowhere else in probability theory. In recent years, Man’ko and coauthors have successfully reconciled quantum and classic probability using a symplectic tomographic model. Nevertheless, there remains an unexplained coincidence in quantum mechanics, namely, that mathematically, the interference term in the squared amplitude of superposed wavefunctions gives the squared amplitude the form of a variance of a sum of correlated random variables, and we examine whether there could be an archetypical variable behind quantum probability that provides a mathematical foundation that observes both quantum and classic probability directly. The properties that would need to be satisfied for this to be the case are identified, and a generic hidden variable that satisfies them is found that would be present everywhere, transforming into a process-specific variable wherever a quantum process is active. Uncovering this variable confirms the possibility that it could be the stochastic archetype of quantum probability.

Abstract
Aims: The purpose of the current study is to explore the prognostic factors of the renal cell carcinoma (RCC) in People living with HIV (PLWH), and to evaluate the postoperative factors associated with the survival in PLWH with RCC.Methods: PLWH with RCC who underwent surgical treatment were retrospectively studied. A single-center analysis was conducted from January 2012 to January 2021. General and postoperative clinical data, including age, gender, smoking and drink history, active antiretroviral therapy (ART), cancer histology, clinical and pathological stage, surgical result, Glasgow Prognostic Score (GPS), the Charlson comorbidity index(CCI), the Karnofsky performance status (KPS）, CD4+ T cell count, CD4/CD8 ratio and survival time were collected.Results: A total of 67 patients were included in our study. The Creatine (77.1±18.8 vs 85.7±12.9, P value=0.032), HGB(mg/dL) (113.6±12.6 vs 139.3±20.8, P value=0.694), the CD4/CD8 ratio (0.68±0.40 vs 0.86±0.33, P value=0.006) and overall survival time (months) (74.93±5.249 vs 96.47±3.28, P value=0.009), the progression free survival time (months) (66.47±6.56 vs 90.65±4.82，P value=0.011). The Cox regression analysis showed that the tumor size and the CD4/CD8 ratio were prognostic factors for survival time.Conclusion: In our retrospective analysis, the survival prognosis of negative group was better than that of PLWH with RCC. The risk factors for overall survival in PLWH with RCC was tumor size and CD4+/CD8+ ratio. The lower CD4/CD8 ratio was a significant predictive factor for shorter overall survival.
Combining agriculture, social and climate indicators to classify vulnerable regions in the Indian semi-arid region
Authors: Kalli Rajesh , Jena Pradyot Ranjan 
Published: November 2021

AbstractClimate change vulnerability is highly counter-productive for agriculture among the arid and semi-arid regions. The study constructs the agriculture vulnerability index for Karnataka, a south Indian state. The state has faced frequent climate-related shocks in the last decade. The district-wise vulnerability index is estimated using longitudinal data considering exposure, sensitivity and adaptive capacity as sub-indices. The results show that the districts in the north interior region of Karnataka are highly vulnerable to the climate change followed by the districts in the south interior and coastal regions. There is an urgent need to prioritize the most vulnerable districts while formulating the development policies to minimize the risk of climate change on agriculture. Specific technical knowledge and support need to be made available to the farmers for informative climate resilience action.

Thrombophilia-related Mutations
Authors: Oz Ozlem , Gonel Ataman 
Published: November 2021

Background:
Alterations in erythrocyte morphology parameters have been identified
and associated with hematological disorders and other chronic and cardiovascular diseases. Erythrocytes
are abundant in thrombus content. Their hemoglobin density and differences in the ratio of
macrocytic and microcytic cells may be associated with hypercoagulopathy in those with a history
of thrombosis.

Objective:
This cross-sectional study aimed to investigate the relationship between hemogram parameters
and thrombophilia genetic parameters.

Method:
A total of 55 patients whose thrombophilia panel was reviewed due to the diagnosis of
thrombosis were included in the study. % MIC, % MAC, % HPO, % HPR and all hemogram parameters
were measured using Abbott Alinity HQ. Prothrombin G20210A, MTHFR C677T, MTHFR
A1298C, Factor V Leiden G169A and PAI-1 4G/5G mutations were studied using Real Time-
PCR.

Results:
The MTHFR C677T mutation was detected in 58.2% of the patients. The Factor V Leiden
mutation was detected in 5.5% of the patients. The MTHFR A1298C mutation was detected in
58.2%, The PAI mutation was detected in 74.5%, and the Factor 13 mutation was detected in 29%
of the patients. Prothrombin G20210A mutation was not detected in any of the patients. Red blood
cell (RBC) and hematocrit (Hct) values were higher in Factor 13 mutant group; the Hgb and Htc
values were higher in the MTHFR C677T mutant group. The plateletcrit (PCT) and platelet (PLT)
values were lower in MTHFR C677T mutant group.

Conclusion:
The MTHFR C677T and Factor 13 mutations may be associated with high Hct and
Hgb, RBC, Hgb, and Htc values, respectively and coagulation tendency in patients with a history
of thrombosis.

Published: November 2021

Introduction:
Noise is increasingly becoming pervasive in occupational health concerning practicing dentists as well as patients. A stimulus such as noise from dental equipment compared to anxiety is often multifactorial and can result from a combination of fear of pain, dental instruments noise, or even upcoming negative events and future threats.

Aim:
This study aimed to assess fear and annoyance levels among adolescents attending a rural dental health centre and compare the acoustic noise levels of dental equipment and its association with fear and annoyance levels among adolescents.

Methods:
The acoustic noise spectra originating from different tools/equipment in a rural dental health centre is assessed using an application named sound meter of a standard mobile android phone (Samsung galaxy grand 2). Following a 15-minute treatment, a questionnaire was filled by a professional investigator through personal interviews with all subjects. The data is subjected to analysis by Statistical Package for Social Sciences version 22.0.

Results:
61.5% of the subjects felt anxious about the anticipatory dental visit, and there was a significant difference observed between genders. Chi-square analysis revealed no significant differences in the fear and annoyance with increasing noise levels in various treatment groups. (p> 0.05).

Conclusion:
In the present study, fear and annoyance levels increased with increasing noise levels of equipment. Annoyance was found to be significantly higher in females.

Authors: Alqahtani Ali R. , Gufran Khalid , Alqahtani Abdulaziz M. , Alazemi Faisal N. , Alzahrani Khaled M. 
Published: November 2021

Background:
Recently, implants have been widely considered as an option for replacing missing teeth. There are several biological conditions that must be considered for the success of an implant. Failure to satisfy any of these factors may result in complications, such as peri-implantitis or failure of the implant.

Aim:
The aim of this study was to evaluate the general dentist's attitude towards the management of peri-implant diseases in Saudi Arabia.

Methods:
A multicenter cross-sectional electronic-based questionnaire was formulated based on the validated questionnaire from a previous study. It was targeted towards the general dental practitioners in Saudi Arabia. The study sample consisted of 721 general dental practitioners. The questionnaire consisted of 17 questions divided into five sections. Pearson's chi-square test was used for inferential statistical analysis with Holm's correction, for adjusted p-value, the alpha at 95% confidence interval was 0.05, and all values below alpha were considered statistically significant.

Results:
The majority of participants had attended an implant training course (51.2%) while the rest had not (48.7%). The majority of the participants (67.3%) thought they need special instruments for the detection of peri-implantitis but only 29.5% thought they do not need any special instruments for the intended purpose. Most participants (79.3%) said they can identify and differentiate between normal and abnormal soft tissue around an implant, while 6.5% of the respondents could not. More than half of the participants (54.8%) could differentiate between peri-implant mucositis and peri-implantitis, and 19.4% had no idea about this. Amoxicillin & metronidazole was considered as the best and most effective antibiotic by the majority of respondents (76%), while only (5%) of dentists selected ciprofloxacin.

Conclusion:
This study concludes by suggesting that most of the participants have adequate knowledge about peri-implant soft tissue assessment, mechanism of periodontitis and peri-implantitis, its initiation and progression along with its management. Most of the participants found the training courses on peri-implantitis to be efficient. It is recommended to conduct more courses and studies that would aim at understanding the pathogenesis, etiology, diagnosis, and treatment of peri-implant diseases so as to increase awareness among general dentists.

Published: November 2021

Objective:
This study aimed to determine the knowledge and attitudes of pregnant Thai women regarding modes of birth.

Methods:
A cross-sectional study was conducted at Songklanagarind Hospital. A total of 605 women with a singleton pregnancy and gestational age >20 weeks who attended an antenatal clinic from September 2018 to June 2019 were recruited. Women having a history of cesarean section, or any condition associated with indications for cesarean section, having a fetus with an obvious anomaly, could not read or write in the Thai language, or could not complete the questionnaire were excluded. Their knowledge and attitudes regarding modes of birth were evaluated through self-administered questionnaires.

Results:
Most women (69.4%) had poor knowledge scores (<5), with a median score of 3 (range, 0-9). Only 14.5% of women knew about serious complications of cesarean section in future pregnancies(placental adherence). Multivariate logistic regression analysis showed that factors associated with adequate knowledge scores (>5) were high educational levels (OR 2.06; 95% CI 1.23-3.47), high incomes (OR 1.96; 95%CI 1.32-2.90), and multiparity(OR 1.73; 95%CI 1.18-2.52). Most women had positive attitudes towards vaginal birth. Only 10.2% of women had a preference for cesarean birth. Factors associated with the preference for cesarean birth were advanced maternal age (OR 3.10; 95%CI 1.72-5.60), having an underlying disease (OR 3.61; 95% CI 1.79-7.25), and poor knowledge scores (OR 2.43; 95% CI 1.21-4.91).

Conclusion:
Most pregnant Thai women had poor knowledge of the modes of birth. However, the majority of women had positive attitudes towards vaginal birth.

Yogyakarta selain dikenal sebagai kota pendidikan, juga dikenal sebagai kota pariwisata. Dewasa ini, wisatawan mancanegara yang berkunjung ke DIY tidak hanya didominasi oleh wisatawan mancanegara dari Eropa, tetapi juga wisatawan dari negara di Asia Timur, khususnya wisatawan China, Korea Selatan, dan Jepang. Perlu diketahui, ketiga negara ini mempunyai karakter yang sangat mencintai budaya sendiri dan sulit untuk menerima budaya orang lain. Akan tetapi, meningkatnya jumlah kunjungan wisman dari Negara Asia timur ini mengindikasikan bahwa daya tarik wisata di DIY sudah bisa masuk dan diterima oleh pasar wisman Asia Timur. Dengan mengetahui karakteristik wisatawan Asia Timur, diharapkan ke depan dapat berguna bagi pengembangan pariwisata DIY khususnya untuk menarik wisman Asia Timur. Teknik pengumpulan data dilakukan dengan menyebarkan kuesioner kepada pemandu wisata berbahasa China, Korea, dan Jepang, wawancara, dan studi kepustakaan. Setelah itu, data dianalisis menggunakan analisis deskriptif kualitatif. Berdasarkan hasil penelitian, wisman Asia Timur yang berwisata ke DIY dalam rentang usia dewasa dan lansia. Mereka menyukai DIY karena keramahan penduduk dan daya tarik wisata budaya. Wisman Asia Timur banyak berkunjung pada musim liburan (peak season). Mereka mendapat rekomendasi dari teman atau agen perjalanan wisata dan melakukan perjalanan seorang diri atau bersama keluarga. Wisatawan merasa puas dengan akomodasi dan fasilitas yang disediakan. Namun, wisatawan juga menyampaikan beberapa keluhan, seperti mahalnya tiket masuk destinasi, masakan lokal yang kurang cocok, minim toilet bersih dan masih banyak sampah. Secara garis besar, DIY berpotensi besar menarik wisman dari Asia Timur karena DIY mempunyai warisan budaya dan alam yang otentik yang tidak dapat ditemukan di negara asal.
