Abstract
Background Cervical arthroplasty with artificial cervical disks has gained popularity as an alternative to anterior discectomy and fusion. The main advantages of disk arthroplasty include maintenance of the range of movement, restitution of disk height and spinal alignment, and reduction of adjacent segment degeneration (ASD). In this article, we aimed to assess the outcomes of the use of a keel-less prosthesis.
Material and Methods We included all the patients who underwent single-level cervical arthroplasties with the Discocerv Cervidisc Evolution for “soft” disk herniation. Clinical assessment included Neck Disability Index (NDI) and visual analog scale (VAS) for neck and arm pain. Radiologic studies investigated the occurrence of ASD and system failure or subsidence. The reoperation rate was also recorded.
Results The study included 35 patients (14 men and 21 women; mean age: 42.5 years; mean follow-up: 57.8 months). There was a significant decrease in VAS neck and VAS arm scores, which went from 7.2 and 6.9 preoperatively to 2.2 and 1.7 postoperatively, 2.2 and 1.6 at 6 months, 2.0 and 1.8 at 1 year, and 2.1 and 1.3 at the last follow-up, respectively. The mean NDI score was 58.0 preoperatively, 19.4 postoperatively, 17.0 at 6 months, 16.1 at 1 year, and 16.2 at the last follow-up. Radiologic studies revealed a preserved range of motion in 33 of 35 patients. No ASD occurred and no reoperation was required.
Conclusions Cervical disk arthroplasty with a keel-less prosthesis can be a safe and effective alternative to fusion for degenerative disk disease in selected patients, with a possible reduction of ASD.

Published: May 2021

AbstractNeonatal intra-abdominal hemorrhage has been rarely reported in the literature. We report a case of splenic injury in a neonate, highlighting the importance of a high-index suspicion in early recognition of this rare and potentially fatal injury. We report the first case of a neonate who had a splenic rupture and underwent successful endovascular treatment.

Abstract
Background Despite the use of vascularized intranasal flaps, endoscopic endonasal posterior fossa defects remain surgically challenging with high rates of postoperative cerebrospinal fluid leak.
Objective The aim of the study is to describe a novel surgical technique that allows complete drilling of the clivus and exposure of the craniovertebral junction with preservation of the nasopharynx.
Methods Two formalin-fixed latex-injected anatomical specimens were used to confirm feasibility of the technique. Two surgical approaches were used: sole endoscopic endonasal approach and transnasion approach. The sole endonasal approach was used in a patient with a petroclival meningioma.
Results In both anatomical dissections, the inferior clivectomy with exposure of the foramen magnum was achieved with a sole endoscopic endonasal approach. The addition of the transnasion approach helped to complete drilling of the inferior border of the foramen magnum and exposure of the arch of C1.
Conclusion This study shows the anatomical feasibility of total clivectomy and exposure of the craniovertebral junction with preservation of the nasopharynx. A more favorable anatomical posterior fossa defect for the reconstruction is achieved with this technique. Further clinical studies are needed to assess if this change would impact the postoperative CSF leak rate.

Published: May 2021

AbstractImage-guided prostate biopsies are changing the outlook of prostate cancer (PCa) diagnosis, with the degree of suspicion on multiparametric magnetic resonance imaging (mp-MRI) being a strong predictor of targeted biopsy outcome. It is important not only to detect these suspicious lesions but also to be aware of the potential pitfalls in mp-MRI prostate imaging. The aim of this pictorial essay is to show a wide spectrum of representative cases, which are frequently misdiagnosed as PIRADS ⅘ while reporting mp-MRI of the prostate. We provide some valuable recommendations to avoid these fallacies and improve mp-MRI of prostate evaluation.
Nutritional Considerations for Female Athletes in Weight Category Sports
Authors: Langan‐Evans Carl , Reale Reid , Sullivan Jordan , Martin Daniel 
Published: May 2021

ABSTRACTWeight making can be described as the process of reducing body mass in events where aesthetics, propulsion or the requirement to meet a specific weight category limit, are considered to be of competitive importance. Cross sectional research specifically focussed on weight category sports, has highlighted behaviours and practices that are similar in athletes of both sexes. Regardless of this and despite parallel participation in weight category sporting events, females are drastically underrepresented in studies examining body mass loss interventions across both chronic and acute timeframes. However, it has been well characterised that these types of body mass loss strategies can be causative of low energy availability, leading to consequences of female athlete triad and relative energy deficiency in sports. Furthermore, female‐specific body composition and physiological systems modulated by the anterior pituitary and ovarian hormones within the menstrual cycle or use of hormonal contraception, can lead to potential outcomes which need to be considered carefully, particularly when employing acute weight loss strategies that are often utilised by weight making athletes. Therefore, the aim of this article serves to review the aforementioned issues, whilst offering practical recommendations via initial assessment, chronic/acute interventions and refeeding/recovery plans to help support the implementation of body mass loss strategies in the context of weight making specifically with female athletes.
Traceable reference dosimetry in MRI guided radiotherapy using alanine: calibration and magnetic field correction factors of ionisation chambers
Authors: Billas Ilias , Bouchard Hugo , Oelfke Uwe , Duane Simon 
Published: May 2021

Abstract
Magnetic resonance imaging (MRI)-guided radiotherapy (RT) (MRIgRT) falls outside the scope of existing high energy photon therapy dosimetry protocols, because those protocols do not consider the effects of the magnetic field on detector response and on absorbed dose to water. The aim of this study is to evaluate and demonstrate the traceable measurement of absorbed dose in MRIgRT systems using alanine, made possible by the characterisation of alanine sensitivity to magnetic fields reported previously by Billas et al (2020 Phys. Med. Biol.
65 115001), in a way which is compatible with existing standards and calibrations available for conventional RT. In this study, alanine is used to transfer absorbed dose to water to MRIgRT systems from a conventional linac. This offers an alternative route for the traceable measurement of absorbed dose to water, one which is independent of the transfer using ionisation chambers. The alanine dosimetry is analysed in combination with measurements with several Farmer-type chambers, PTW 30013 and IBA FC65-G, at six different centres and two different MRIgRT systems (Elekta Unity™ and ViewRay MRIdian™). The results are analysed in terms of the magnetic field correction factors, and in terms of the absorbed dose calibration coefficients for the chambers, determined at each centre. This approach to reference dosimetry in MRIgRT produces good consistency in the results, across the centres visited, at the level of 0.4% (standard deviation). Farmer-type ionisation chamber magnetic field correction factors were determined directly, by comparing calibrations in some MRIgRT systems with and without the magnetic field ramped up, and indirectly, by comparing calibrations in all the MRIgRT systems with calibrations in a conventional linac. Calibration coefficients in the MRIgRT systems were obtained with a standard uncertainty of 1.1% (Elekta Unity™) and 0.9% (ViewRay MRIdian™), for three different chamber orientations with respect to the magnetic field. The values obtained for the magnetic field correction factor in this investigation are consistent with those presented in the summary by de Pooter et al (2021 Phys. Med. Biol.
66 05TR02), and would tend to support the adoption of a magnetic field correction factor which depends on the chamber type, PTW 30013 or IBA FC65-G.

Abstract
In the next decades, ultra-high-energy neutrinos in the EeV energy range will be potentially detected by next-generation neutrino telescopes. Although their primary goals are to observe cosmogenic neutrinos and to gain insight into extreme astrophysical environments, they can also indirectly probe the nature of dark matter. In this paper, we study the projected sensitivity of up-coming neutrino radio telescopes, such as RNO-G, GRAND and IceCube-gen2 radio array, to decaying dark matter scenarios. We investigate different dark matter decaying channels and masses, from 107 to 1015 GeV. By assuming the observation of cosmogenic or newborn pulsar neutrinos, we forecast conservative constraints on the lifetime of heavy dark matter particles. We find that these limits are competitive with and highly complementary to previous multi-messenger analyses.

Published: May 2021

Abstract
In the present study, the linear analysis of electrodynamic Rayleigh-Taylor instability(ERTI) in a thin layer of an incompressible two fluids with a poor conducting fluid confined above by an interface with heavier fluid and below with a rigid boundary subjected to boundary roughness is analyzed. A dispersion that accounts for the growth rate is derived using the approximations defined by Rudraiah et al.,[(1996) and stability is discussed theoretically as well as numerically. The influence of the combined effect of electromagnetic fields, surface tension, power-law fluid, boundary roughness and layer thickness on the ERTI is investigated and shown graphically for above various physical parameters on the stability of the system. It is observed that electric field, magnetic field, power-law fluid, porous parameter and boundary roughness have stabilizing effect on the system whereas Bond number and layer thickness destabilizes the interface.

Abstract
Marine waste, especially plastic waste, is a complex problem faced by areas close to the beach/coastal area. This problem also occurs in Kendari Bay which has a unique character because of its position stretching in the middle of Kendari City, its shape is like a horse’s footprint and as a mainstay tourist attraction in Southeast Sulawesi. This study aims to analyze the distribution of microplastic abundance in sediments and marine biota, analyze water quality in the microplastic abundance distribution area, and determine efforts to mitigate pollution of plastic waste in Kendari Bay. A sampling of sediments and biota from 2 stations (settlement and port) using paralon pipes at depths of 0-5 cm and 5-10 cm. Seawater quality parameters are parameters related to solid waste pollution based on UNESCO-WHO-UNEP and the method for water quality analysis refers to APHA-AWWA-WEF. The results showed that the types of microplastics found were film, fragment, and fiber. The average abundance of microplastics in Station I (Mata Village, Kendari City) and Station II (Kendari Archipelago Harbor) at a depth of 0-5 cm range from 426.82-424.92 particles/kg. This value is higher than the microplastic abundance at 5-10 cm depth, which is between 276.50 to 363.74 particles/kg. The average abundance of film-type microplastics and fragments at 0-5 cm depth was higher at Station I (203.75 particles/kg and 359.90 particles/kg). The microplastic category of fragments/debris at a depth of 5-10 cm, was found at Station II (409.06 particles/kg). Biota found in Station I sediments were blood shells (AnadaraSp) With microplastic fragment type (1 particle) and fiber type (2 particles) with an average abundance of 0.12 particles/Ind. Fiber-type microplastics are found in tofu skin (Maretrixmaretrix) of 5 particles with an average abundance of 0.5 particles/Ind. and Violin Crab (Uca), 1 particle with an average abundance of 0.04 particles/Ind. Water quality in the area of microplastic abundance found NH3, BOD, Phosphate (PO43-), Nitrate (NO3−), Phenol (C6H5OH), detergent and fat oil content have exceeded the quality standard. Mitigation efforts that can be done are 6R, separating the types of waste from the beginning, encouraging the role of government through education and regulation, research and technology support as well as bay cleaning measures so as to beautify the bay and improve the comfort of the local community and visitors so that the function of Kendari Bay as a tourist area the mainstay coast of Southeast Sulawesi remains sustainable.

Abstract
Remote sensing is a technique that can be applied for observing oceanographic paramaters such as content of sea surface temperature and chlorophyll-a. The study aims to analyze the parameters of Sea Surface Temperature and Chlorophyll-a by using Aqua Modis Satellite to see the spatial and temporal distribution of the two paramaters on the distribution of CPUE of Mackerel (Scomberomorus commerson).Conducted for 2 months from May-June 2019 this study was held in the waters area of Naukenjerai District, Merauke Regency. The results showed the concentration of sea surface temperature in May was warmer in the range of 26.56 – 28.42 °C compared to June, where the temperature was cooler in the range of 25.43 – 26.94 °C. Meanwhile the concentration of chlorophyll-a in May was seen to be low around 0.3-1.73 mg/m3 which compared to June the concentration was relatively high around 1.45-2.36 mg/m3. The highest distribution of CPUE of Mackerel was found in June, which was 89 kg and the lowest CPUE Mackerel in May was around 22 kg. Therefore in June there is a great potential for capturing Mackerel.

Abstract
The application of biological agents can be done singly or in combination to increase its effectiveness. Trichoderma sp. fungi, Bacillus sp. and fluorescent psudomonads bacteria has been widely used as a biological control agent for plant pathogens. The purpose of this study was to determine the growth and reproduction of Trichoderma sp. in the presence of Bacillus sp., or fluorescent psudomonads. The research was carried out in vitro by dual and double layer culture method. The variables observed were the inhibition zone, the total and, viability of conidia of Trichoderma sp. The data obtained were compared using the two free sample T test and analysis of variance was continued with Duncan’s multiple range test. Based on the results of this study concluded that the growth and reproduction of Trichoderma sp inhibited by the presence of Bacillus sp. or fluorescent psudomonads, but does not reduce the viability of conidia. This shows that in Trichoderma sp. with Bacillus sp. or fluorescent psudomonads can be applied simultaneously.

Published: May 2021

Abstract
The study aimed to determine the effect of ratio zeolite and TiO2 toward the particle size of zeolite/TiO2 composites. The raw material used was natural zeolite of South Sulawesi. Zeolite acts as a support catalyst of TiO2 synthesized using impregnation method. The ratio of zeolite:TiO2 (w/w) was 3:1; 3:1.5; 3:2; 3:2.5 and 3:3 mixed with ethanol, then calcined at 500 oC for 5 hours. The powder of zeolite/TiO2 composites characterized by X-Ray Diffraction (XRD) and calculated the particle size using Debye Scherer equation. The results showed that the zeolite phase contained in zeolite/TiO2 composite is modernite and TiO2 catalyst phase is anatase with a tetragonal structure. The average particle size of composites increased with the increasing amount of catalyst impregnated. The smallest average size occur at zeolite:TiO2 of 3:1with 42.86 nm and the largest average size occur at 3:3 with 52.98 nm.

Abstract
Few previous studies show pharmacological potencies of Xestospongia sp. and have not been explored further about its antibacterial activity. Thus, this study aims to isolate and identify the isolates from Xestospongia sp. and testing their antibacterial activity. Xestospongia Sp. was macerated with methanol then isolated and was purified by using vacuum liquid chromatography (VLC), radial chromatography (RC) and thin-layer chromatography (TLC). Isolated compounds then analyzed, identified, and determined their structures using 1H-NMR Spectrophotometer and by comparising data to references and ChemDraw 8.0. Compounds obtained with various concentrations (1000; 500; 100 μg/mL) then tested against Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 35218 using agar well-diffuse method. According to the study, two compounds isolated which were Saringosterol (isolate X1) and predicted-compound halenaquinone (isolate X2). The antibacterial test showed that isolate X1 was unable to inhibit bacteria‘s’ growth at each concentration, and isolate X2 showed antibacterial activity against S. aureus ATCC 25923 and E. coli ATCC 35218 at concentration 1000 and 500 μg/mL. In conclusion, 2 compounds successfully isolated from methanolic extract of Xestospongia sp. which were Saringosterol and predicted-compound halenaquninone, and only predicted-compound halenaquinone showed antibacterial activity at concentration 1000 and 500 μg/mL.
Implementation of the Simple Multi Attribute Ranking Technique Method as a Model for Decision Making in Determining the Talents and Interests of Children in Continuing Education
Authors: Lintang M , Pandiangan N , Zubaedah R 
Published: May 2021

Abstract
Talent and interest are very influential on students in the process of their development and learning. This is because every child needs an education program that matches their talents and interests. Many problems occur due to mistakes of parents or teachers in determining talent and asking students so mistakes in determining education still tend to be incorrect. So students find it difficult to adapt to the education they face because it is not in accordance with their abilities and potential. Therefore, we need a modeling of decision making based on the criteria of talent and interests of children using the Simple Multi Attribute Ranking Technique modeling. The implementation of the SMART method in this study is able to provide solutions to the problem of decision making talents and interests of children. This study uses a sample of 15 student data which is then entered into the computation of the SMART calculation method. The result is that 3 students who were sampled were able to have grades above the standard or scores above 70 points that have been set based on predetermined rules. While the other 12 students have the final result below the standard that has been set which is below the value of 70 points.
