Additive Manufacturing of Ti-6Al-4V with Carbon Nanotube Composite Material
Authors: Vevers A. , Kromanis A. 
Published: December 2023

Abstract
This research is dedicated to investigating whether mechanical properties of Ti-6Al-4V (Titanium Grade 5) base material for additive manufacturing processes can be improved by addition of carbon nanotubes in the base material. Based on other research results with other materials, the assumption was made that reinforcing Ti-6Al-4V material with carbon nano-tubes should improve mechanical properties of the base material by 15–20 % in the additive manufacturing process. The research was divided in two steps, the first one was to investigate pure Ti-6Al-4V material and find optimal additive manufacturing processing parameters, which could maintain necessary quality standards and achieve material density levels higher than 98 % and tensile strength higher than 1000 MPa. The second part was to mix base powder with carbon nanotubes and using previously obtained processing parameters print test samples to investigate how a carbon nanotube concentration in a base powder would influence mechanical properties of the base material.
Retropharyngeal calcific tendinitis in the neurological emergency unit, report of three cases and review of the literature
Authors: Filipovic Tatjana , Avsenik Jernej 
Published: December 2023

Abstract

Background
Retropharyngeal calcific tendinitis (RCT) is a relatively benign condition of calcination of the longus colli muscle tendon of unknown origin, which causes severe acute neck pain. However, it is often not recognised, which leads to delayed diagnosis and unnecessary treatment.

Patients and methods
We have searched PubMed and Google Scholar for publications which reported at least one patient with RCT and were published in the last 20 years. The literature was then analysed according to the PRISMA-S protocol. We also report three patients with RCT presenting at the Neurological Emergency Unit, University Medical Centre, Ljubljana, Slovenia, from 1 January 2020 to 1 June 2022. We discuss their clinical presentation and differential diagnosis, explain our decision-making process, and briefly describe the clinical course. Case reports have been performed according to the CARE protocol.

Results
We have analysed a total of 112 titles with 231 patients. The most frequent symptoms and signs were: neck pain, neck stiffness and odynophagia, as was the case in our reported cases.

Conclusions
RCT is a dramatic yet self-limiting condition, often not recognised in time. An effort should be made to increase neurologists’ awareness about this condition.

Abstract

Background
Cardioprotection is valued in radiotherapy for patients with left-sided breast cancer. Deep inspiration breath-hold (DIBH) technique can achieve cardioprotection well. However, during DIBH, the extent to which the heart enters the radiation field is affected by the movement of the thorax and diaphragm. The aim of this study was to analyze the correlation between the maximum distance of the heart entering the field (maximum heart distance, MHD) and thoracic diameter changes and diaphragmatic descent in left-sided breast cancer patients during DIBH.

Patients and methods
Ninety-eight patients with left-sided breast cancer were included in this retrospective study. They performed simulation in Sentinel-guided DIBH, and two sets of CT images were collected under both free breathing (FB) and DIBH, and diaphragm positions, anteroposterior thoracic diameter (ATD), transverse thoracic diameter (TTD), gating window level (GWL), and MHD were measured, and the change (Δ) of each parameter in DIBH relative to that in FB were calculated. Pearson or Spearman test were used to analyze the correlation between ΔMHD and the changes in other parameters.

Results
For all patients with DIBH, the average of ΔMHD was −8.3 mm, and the average of ΔATD and ΔTTD were 11.0 and 8.6 mm, and the median of both left diaphragmatic descent (LDD) and right diaphragmatic descent (RDD) were 35.0 mm, and the median of GWL was 11.1 mm. The correlation coefficients between MHD decrease (ΔMHD) and LDD, RDD, and ΔTTD were −0.430 (p = 0.000), −0.592 (p = 0.000) and 0.208 (p = 0.040), respectively, but not significantly correlated with ΔATD or GWL.

Conclusions
The MHD decrease showed a moderate correlation with diaphragmatic descent In Sentinel-guided DIBH for patients with left-sided breast cancer, while there was a weak or no correlation with thoracic diameter changes or GWL. Abdominal breathing can lower diaphragm more and may be more beneficial to the heart stay away from tangential field.

Published: December 2023

Abstract

Background
Computer-aided diagnosis (i.e., texture analyses) tools are becoming increasingly beneficial methods to monitor subtle tissue changes. The aim of this pilot study was to investigate short-term effect of platelet rich plasma (PRP) treatment in supraspinatus and common extensor of the forearm tendinosis by using texture analysis of ultrasound (US) images as well as by clinical questionnaires.

Patients and methods
Thirteen patients (7 male and 6 female, age 36–60 years, mean age 51.2 ± 5.2) were followed after US guided PRP treatment for tendinosis of two tendons (9 patients with lateral epicondylitis and 4 with supraspinatus tendinosis). Clinical and US assessment was performed prior to as well as 3 months after PRP treatment with validated clinical questionnaires. Tissue response in tendons was assessed by using gray level run length matrix method (GLRLM) of US images.

Results
All patients improved of tendinosis symptoms after PRP treatment according to clinical questionnaires. Almost all GLRLM features were statistically improved 3 months after PRP treatment. GLRLM-long run high gray level emphasis (LRLGLE) revealed the best moderate positive and statistically significant correlation after PRP (r = 0.4373, p = 0.0255), followed by GLRLM-low gray level run emphasis (LGLRE) (r = 0.3877, p = 0.05).

Conclusions
Texture analysis of tendinosis US images was a useful quantitative method for the assessment of tendon remodeling after minimally invasive PRP treatment. GLRLM features have the potential to become useful imaging biomarkers to monitor spatial and time limited tissue response after PRP, however larger studies with similar protocols are needed.

Published: December 2023

Abstract

Background
This study aimed to evaluate the predictive and monitoring role of somatostatin receptor (SSTR) positron emission tomography-computed tomography (PET/CT) and clinical parameters in patients with neuroendocrine liver metastases (NELM) from pancreatic neuroendocrine tumors (pNET) receiving capecitabine and temozolomide (CAPTEM).

Patients and methods
This retrospective study included twenty-two patients with pNET and NELM receiving CAPTEM who underwent pre- and post-therapeutic 68Ga-DOTATATE/-TOC PET/CT. Imaging (including standardized uptake value [SUV] of target lesions [NELM and pNET], normal spleen and liver) and clinical (Chromogranin A [CgA], Ki-67) parameters were assessed. Treatment outcome was evaluated as response according to RECIST 1.1, progression free survival (PFS) and overall survival (OS).

Results
The median PFS (mPFS) was 7 months. Responders had a significantly longer mPFS compared to non-responders (10 vs. 4 months p = 0.022). Median OS (mOS) was 33 months (mOS: responders = 80 months, non-responders = 24 months p = 0.182). Baseline imaging showed higher SUV in responders, including absolute SUV, tumor-to-spleen (T/S), and tumor-to-liver (T/L) ratios (p < 0.02). All SUV parameters changed only in the responders during follow-up. Univariable Cox regression analysis identified baseline Tmax/Smean ratio and percentage change in size of pNETs as significant factors associated with PFS. A baseline Tmax/Smean ratio < 1.5 was associated with a shorter mPFS (10 vs. 4 months, (p < 0.05)). Prognostic factors for OS included age, percentage change in CgA and in T/S ratios in univariable Cox regression.

Conclusions
SSTR-PET/CT can be useful for predicting response and survival outcomes in pNET patients receiving CAPTEM: Higher baseline SUV values, particularly Tmax/Smean ratios of liver metastases were associated with better response and prolonged PFS.
Imaging microvascular changes in nonocular oncological clinical applications by optical coherence tomography angiography: a literature review
Authors: Hren Rok , Sersa Gregor , Simoncic Urban , Milanic Matija 
Published: December 2023

Abstract

Background
Optical coherence tomography angiography (OCTA) is an emerging imaging modality that enables noninvasive visualization and analysis of tumor vasculature. OCTA has been particularly useful in clinical ocular oncology, while in this article, we evaluated OCTA in assessing microvascular changes in clinical nonocular oncology through a systematic review of the literature.

Method
The inclusion criterion for the literature search in PubMed, Web of Science and Scopus electronic databases was the use of OCTA in nonocular clinical oncology, meaning that all ocular clinical studies and all ocular and nonocular animal, phantom, ex vivo, experimental, research and development, and purely methodological studies were excluded.

Results
Eleven articles met the inclusion criteria. The anatomic locations of the neoplasms in the selected articles were the gastrointestinal tract (2 articles), head and neck (1 article) and skin (8 articles).

Conclusions
While OCTA has shown great advancements in ophthalmology, its translation to the nonocular clinical oncology setting presents several limitations, with a lack of standardized protocols and interpretation guidelines posing the most significant challenge.

Published: December 2023

Abstract
Permeation grouting treatments can be considered a well-established ground improvement strategy in urban built environments, where an accurate fine-tuning of its components can lead to tailored and efficient interventions. However, how to improve its overall environmental impact remains an open question. Using the Life Cycle Assessment (LCA) approach emphasizing the construction phase, this research highlights the leverages that can improve the environmental performance of this geotechnical construction process. The alternative approaches in terms of materials and processes are identified, quantified, and compared using the standard output of the LCA analysis and represent the ideal input for the three-phased sustainability assessment method for geotechnical infrastructure developed by the authors.

Authors: Legrand Geoffrey 
Published: December 2023

L’usage de symboles dans l’éducation religieuse peut-elle servir la formation au dialogue interconvictionnel et interreligieux ? Pour répondre à cette question, l’auteur de ce livre examine plusieurs concepts – « expérience », « dialogue », mais aussi « Salut » et « Révélation » – du point de vue de la théologie chrétienne. Il présente divers modèles d’éducation religieuse, anciens ou contemporains, en portant une attention particulière à la place occupée par les symboles. L’enquête se veut un plaidoyer pour le développement d’une grammaire du symbolique et une invitation au développement des pédagogies interreligieuses, dans le but d’apprendre aux élèves à construire ensemble le monde de demain.

Стаття присвячена проблемі формування цінностей у студентів майбутніх технічних спеціальностей під час навчально-пізнавальної діяльності.
Формування ціннісних орієнтацій студентів відбувається лише у процесі навчальної діяльності, оскільки цей процес пов’язаний з системою відносин, до якої залучений суб’єкт. Тому формування ціннісних орієнтацій студентів треба розглядати як процес засвоєння ними суспільних цінностей, знань, соціальних норм і правил, що можливо лише при науково-організаційному забезпеченні аксіологічного підходу до професійної підготовки студентів технічних закладів. Власне психолого-педагогічний аспект теорії цінностей корелює з культурологічним аспектом у процесі формування майбутнього фахівця.

Published: December 2023

Compliance has become one important thing in implementing health protocol during the covid-19 pandemic period. It is the key of success for some schools or education institutions in applying the regulation of limited face-to-face learning (PTMT) during the pandemic. PTMT regulation has been implemented to support the teaching and learning process when the students were at schools. In the implementation of the program, there were some schools, Junior High School (SLTP) and Senior High School (SLTA), both public and private, where the students did not obey the health protocol regulation and there were incomplete supporting facilities available at the schools. This research aims at finding out the differences between health protocol implementation compliance in SLTP and SLTA during PTMT.
Methods: The design of the research was comparative descriptive utilizing quantitative technique. The sampling applied stratified random sampling technique. The total respondents were 100 students where 25 students were taken from each school. The data collection used observation, demographic data, and implementation of health protocol compliance questionnaire. The data analysis applied Mann-Whitney’s test. The differences in compliance level shows p-value score of 0.512 > 0.05 indicating that the compliance levels in SLTP students, both public and private, are not different. The p-value score of 0.274 > 0.05 means that there is no different compliance level in SLTA students, both public and private. The p-value score of 0.464 > 0.05 indicates that there is no different compliance level in SLTP and SLTA students. There is no different compliance level in public and private SLTP students during PTMT, there is no different compliance level in public and private SLTA students during PTMT, and there is no different compliance level in SLTP and SLTA students during PTMT.
"Slum Clearance" in 1890s Wellington
Authors: Cox Elizabeth 
Published: December 2023

In 1892, a remarkable map of Wellington was completed. Stretching from Thorndon in the north to Berhampore to the south, and taking in the teeming inner-city areas of Te Aro and Newtown, the remnants of Māori kāinga, the town belt, the Basin Reserve, the prison, "lunatic asylum" and hospital, reclamations and every street in between. The map, drawn by engineer and surveyor Thomas Ward, is actually 103 maps, drawn on A1 sheets. On the map, the exact footprint of every single building in Wellington is recorded every commercial building and house, every garden shed and outdoor toilets. Bay windows and verandahs are carefully drawn. Data is recorded for every building, including how many rooms it contains, what the roof and walls are made of and how many storeys it has. Legal titles are exactly mapped, as are the city's streams and even the street lights. Once complete, one full pristine set of the maps was set aside and preserved intact. Another set of the maps was updated regularly, for approximately the next ten years. For that decade, we can follow every change in the city, down to the smallest detail such as the replacement of slate rooves with corrugated iron, but also bigger-scale work such as the reconfiguration of whole streets.
The Thomas Ward map is a touchstone for the history of our city. It is used every day by Wellington's archaeologists and historians. Wellington City Council provides the map online as an digital overlay over modern satellite images of the city, allowing us to compare the city of 1892 to the city of today. A well-known feature of the history of Wellington in the 1890s was the outbreak of typhoid and other diseases in the inner-city, a result of overcrowding and lack of clean water. To combat this, a number of "slum clearances" were ordered by the city council, resulting in whole streets of working-class houses being demolished. This paper, a part of a much larger project, will examine some of the stories shown in the two sets of maps, with a particular focus of the changed landscape of the inner-city brought about by this "slum clearance" work of the 1890s.

Published: December 2023

Salah satu sumber masalah lingkungan yaitu limbah kaca baik itu dari industri maupun rumah tangga. Kaca merupakan salah satu sampah inorganik yang sangat berbahaya karena kaca tidak dapat membusuk. Pada penelitian ini akan difokuskan pada pemanfaatan limbah kaca yang berbentuk botol sirup berwarna putih yang dihaluskan menjadi tepung kaca sebagai material substitusi semen dalam pembuatan beton normal. Penilitian ini dilakukan dilaboratorium Universitas Malikussaleh. Botol kaca yang digunakan berasal dari Krueng Mane Aceh Utara, kemudian dihaluskan sehingga lolos saringan no.200. Kuat pantul dan kuat tekan dilakukan terhadap sampel benda uji berbentuk silinder dengan ukuran 15cm x 30cm sebanyak 12 benda uji, dengan faktor air semen yang digunakan 0.435. Semen yang digunakan adalah produksi Andalas Tipe I. Substitusi tepung kaca dengan semen dilakukan sebesar 0%, 10%, 15%, 20% yang masing-masing sampel tersebut diuji pada umur 28 hari. Dari hasil pengujian kuat pantul beton normal (BN) didapat 34.58 Mpa, untuk beton BK1 (10%), BK2 (15%), BK3 (20%) didapat hasil kuat pantul masing-masing 29,44 Mpa, 30,24 Mpa, 31,08 Mpa. Sedangkan dari hasil pengujian kuat tekan untuk sampel BN didapat 26,23 Mpa, dan untuk sampel BK1, BK2, BK3 didapat hasil kuat tekan masing-masing 25,85 Mpa, 25,48 Mpa, 24,53 Mpa. Hubungan kuat pantul dengan kuat tekan dapat dinyatakan dengan persamaan: untuk sampel BN, y = 2.1088x – 46.885 (R2= 0.8414), untuk sampel BK1, y = 1.1645x – 8.4059 (R2= 0.9635), untuk sampel BK2, y = 1.1917x – 10.385 (R2 = 0.9994), untuk sampel BK3, y = 0.924x - 4.1922 (R2 = 0.9293). Hasil pengujian kuat pantul dan kuat tekan beton menunjukkan penurunan yang tidak signifikan. Kuat pantul mengalami penuruannya sebesar 11% - 15%, sedangkan untuk kuat tekan penurunannya sebesar 2% - 7%.
