Dark matter as one of the cosmos’ ingredients or constituents has been searched for in various experiments. This review presents some of the searches for dark matter while focusing on the LHC mainly. In order to present various searches, it describes theoretical models followed by experimental verification. Since there are three types of searches, among which most significant are direct and indirect ones, we will give an overview and short comparison between the two, with an emphasis on the advantages and disadvantages of collider and non-collider searches. This review brings an argumentative approach for the collider’s point of view since searches for dark matter in colliders are veritably ambitious regarding direct and indirect Dark Matter detection methods. LHC starts its Run 3 in 2021, and here we present results from the ATLAS experiment from Run 2 and bring some theoretical expectations from LHC in Run 3.

The present review paper provides a systematic insight into the studies published so far when it comes to the research on the cost and performance optimisation in the parcel delivery phase. Globalisation, as well as the new trends, such as selling online, directly influences the demands for the delivery of goods. Demand for the delivery of goods proportionally affects the transport prices. A great majority of deliveries is carried out in densely populated urban areas. In terms of costs, the greatest part in the courier organisations costs is observed in the technological phase of parcel delivery, which is at the same time the least efficient. For that reason, significant improvement of performance and cost optimisation in the very delivery phase is a rather challenging field for the researchers. New algorithm-based technologies, innovations in the logistics and outsourcing of individual technological phases are ways by means of which one strives to enhance the delivery efficiency, to improve performance and quality, but also to optimise the costs in the last phase of delivery. The aim of the present paper is to offer a systematic review into the most recent research in the field of technology, innovations and outsourcing models with the aim of reducing the cost and enhancing the productivity and quality in parcel delivery.

This research aimed to determine the differences between the junior (U20) water polo players of national teams of Montenegro, and Australia regarding their anthropometric characteristics and body composition. The first sub-sample of the subjects consisted of 18 water polo players of the Montenegrin national team, who occupied the sixth position on the FINA World Men’s Junior Water Polo Championship in Kuwait 2019. The second sub-sample consisted of 13 water polo players of the Australian national team, who occupied the eleventh position on the championship. The players were tested at the final preparations just before the World Championship. Anthropometric characteristics were evaluated using a battery of eight tests: body height, body weight, triceps skinfold, biceps skinfold, skinfold of the back, abdominal skinfold, upper-leg skinfold, lower leg skinfold; body composition was evaluated using a battery of three tests: body mass index, fat percentage, and muscle mass. The results of the t-test revealed that the water polo players of the two national teams do not have statistically significant differences in the variables. The results obtained in this research showed average team values for the estimated variables of water polo players of the two national teams (U20) who participated in the World Championship. That can serve as possible model parameters for all teams who want to participate in the U20 water polo World Championship. Differences in classification among water polo players may be related to the motor abilities, as well as technical and tactical parameters, as their anthropometric parameters were found to be similar.

Based on the computed tomography (CT) images it is not possible to see all the lymph nodes that belong to the stomach. In radiotherapy, for a clinical target volume (CTV) delineation based on CT images, it is necessary to determine the appropriate margin around the corresponding blood vessels to make sure that all the required lymph nodes will be irradiated. The larger margin will certainly cover all the lymph nodes but it can also produce an increase of the received dose in the normal tissues. While a smaller margin can eventually spare the normal structures as a consequence it brings a higher risk of missing the suspected lymph nodes. The aim of this study was to analyse the radiation doses received by some organs at risk (OARs) in the case of the three-dimensional conformal radiotherapy (3DCRT) treatment of the gastric cancer, for lymph node CTV margin sizes 5 mm, 7 mm and 10 mm. The study included 40 patients undergo the external beam radiotherapy (EBRT) treatment of gastric cancer. The one-way analysis of variance (ANOVA) with repeated measures test and Friedman’s nonparametric test have been used for testing the statistical significance of differences among the examined groups. The difference between the examined groups has been considered significant if p < 0.05. The statistically significant differences in the dose contributions to the observed OARs (spinal cord, heart, small bowel and colon), among the examined CTVs, were found.

Phishing is a network attack in which attacker generates a replica of current legitimate site to contrivance the users into submitting their personal and sensitive information. A good anti-phishing solution should have rapid access time and rapid detection rate, but most of the existing solutions fail to satisfy it. A new method is proposed to prevent phishing attack which evaluates the URL Characteristics and cross check with the white-list. The proposed method has higher access time and higher detection rate than other methods. Whenever the user opens a website for the first time which is not available in the white-list, the algorithm proposed here examines the webpage using URL characteristics. The experimental results depict the accuracy of proposed method having accuracy of 93.8% with less negative rate.

The paper describes the PyChart module (aimed at analysis and visual view of 2D/3D Charts), which was created with the help of free and Open Source resources, using Python as a programming language and wx.Python as a graphical user interface toolkit. The chart data is imported from a Excel/CSV file with a template structure and is drawn in the PyChart module as XY or XYZ curves similar with Excel scatter with smooth lines and markers style. The main functions of the charts are activated using the toolbar. The module is provided with zooming instruments (fit, pan, zoom in, zoom out), cubic spline curves interpolation, chart intersection with constant X, Y or Z values, visual follow of the 2D chart points to view coordinates, export of data in Windows Clipboard, Excel or Microsoft Word format and saving the chart as a image file.

In 2013, the Journal “Periodical of Engineering and Natural Sciences” was launched. By now, the journal achieved a global spread of authorship and Editorial Board. In this period, we have been publishing mainly original research articles, reviews, and case studies. In addition to the current article types, we are going to start publishing Book reviews, Minireviews, Short Communication, Commentaries, Methodology/Method starting from the next Issue. To familiarize authorship with the different types of articles we publish, here below each of them is particularly described, including the paper structure and length.

The rapid urbanization of cities creates a need for construction of new collective residential buildings in all major cities of Bosnia and Herzegovina. However, residential facilities are often built without any analyses, creating unsustainable architectural structures with a very high market price. The traditional monolith construction of residential units does not allow for any transformation or adaptation of the system. This paper aims to explore the possibility of the application of alternative solutions for the construction of sustainable collective residential buildings using shipping and prefabricated modular containers. Analyzing Bosnia and Herzegovinas market, it was found that there are no empty shipping container storages, but there are a few companies which produce prefabricated modular containers which are currently not planned for residential use. These prefabricated units could be transformed and used for the construction of sustainable residential buildings with the application of simple interventions suggested in this paper. The usage of prefabricated modular containers offers the possibility of transformation of space, simple assembly and disassembly, placement on existing structures, and the lower price of living area.

The study aimed to examine the quality of honey from the Middle Podrinje area (Bosnia and Herzegovina). The research included a total of 21 samples of honey from the Middle Podrinje area: 12 samples of honey florals (municipalities of Srebrenica and Milici), 9 samples of acacia honey (municipalities of Zvornik and Bratunac). Physico-chemical parameters were determined as the main composition criteria for quality assessment in honey samples: mass fraction of water, total acidity, electrical conductivity, and ash. Samples of honey florals are of poorer quality compared to acacia honey, two samples had values of water content and acidity above the values prescribed by the Regulation. Statistical analysis showed that there is a statistically significant difference between the arithmetic means of the water content for floral honey, the electrical conductivity of acacia honey, and the free acid content for both types of honey. Honey samples that met the criteria prescribed by the Regulation were sensory evaluated by experienced analysts. Two samples of floral honey that did not meet the criteria prescribed by the Regulation were not sensory evaluated. Based on sensory analysis, samples of floral honey from the municipality of Milici had better sensory characteristics compared to the same type of honey from the municipality of Srebrenica. Acacia honey from the municipality of Zvornik was rated better than honey from the municipality of Bratunac.

The aim of this randomized prospective study was to evaluate the quality of life (QoL) using the "Seattle Angina Questionnaire" (SAQ) in patients with chronic total occlusion (CTO) in coronary arteries treated with either percutaneous coronary intervention (PCI) or optimal medical therapy (OMT), or only with OMT.The potential benefits of recanalization of CTO by PCI have been controversial because of the scarcity of randomized controlled trials.A total of 100 patients with CTO were randomized (1:1) prospectively into the PCI CTO or the OMT group (50 patients in each group). There were no baseline differences in the SAQ scores between the groups, except for physical limitation scores (P = 0.03). During the mean follow-up (FUP) of 275 ± 88 days, patients in the PCI group reported less physical activity limitations (72.7 ± 21.3 versus 60.5 ± 27, P = 0.014), less frequent angina episodes (89.8 ± 17.6 versus 76.8 ± 27.1, P = 0.006), better QoL (79.9 ± 22.7 versus 62.5 ± 25.5, P = 0.001), greater treatment satisfaction (91.2 ± 13.6 versus 81.4 ± 18.4, P = 0.003), and borderline differences in angina stability (61.2 ± 26.5 versus 51.0 ± 23.7, P = 0.046) compared to patients in the OMT group. There were no significant differences in SAQ scores in the OMT group at baseline and during the FUP. There was a statistically significant increase in all five domains in the PCI group.Symptoms and QoL measured by the SAQ were significantly improved after CTO PCI compared to OMT alone.

Abstract Orbital metastatic lesions are rare entities1-3 best treated with radical surgical resection with preservation/improvement of neurological and visual function.1-9 Renal cell metastases, in particular, respond less favorably to radiation.9 To our knowledge, an operative video of microsurgical resection of a renal cell carcinoma metastasis to the superior orbital fissure and orbit has not been reported. A patient presented with worsening right eye vision as demonstrated on preoperative visual field testing and found to have a 3 × 1 × 1 cm lesion in the orbit and superior orbital fissure. The patient was placed supine and stealth neuronavigation was used to aid in tumor localization and extension. A cranio-orbital craniotomy and pretemporal exposure2,10,11 were performed to allow extradural dissection of the dura propria off the lateral wall of the cavernous sinus. Right-sided extradural cranial nerves II, III, IV, V1, and V2 were identified, and a high-speed diamond drill was used to perform extradural anterior clinoidectomy and optic nerve decompression. Microsurgical resection of the intraorbital tumor components was performed by the senior author (KIA) to delineate the plane between tumor and periorbita. An oval-shaped dural opening was made to resect the dura involved by tumor, confirmed on histological analysis, followed by closure via dural allograft. The patient's right-sided visual field improved markedly after surgery. Metastatic renal cell carcinoma of the orbit should be resected while preserving and improving preoperative neurological and visual function. The orbitocranial pretemporal approach offers wide visualization to achieve surgical resection. The patient provided written consent and permission to publish her image.
