Over the past three decades numerous numerical methods for solving the time-dependent Schr\"odinger equation within the single-active electron approximation have been developed for studying ionization of atomic targets exposed to an intense laser field. In addition, various numerical techniques for extracting the photoelectron spectra from the time-dependent wave function have emerged. In this paper we compare photoelectron spectra obtained by either projecting the time-dependent wave function at the end of the laser pulse onto the continuum state having the proper incoming boundary condition or by using the window-operator method. Our results for three different atomic targets show that the boundary condition imposed onto the continuum states plays a crucial role for obtaining correct spectra accurate enough to resolve fine details of the interference structures of the photoelectron angular distribution.

Objectives To determine the optimal cut-off points of handgrip strength (HGS) to identify the undernutrition risk among individuals older than 65 years of age in Bosnia and Herzegovina. Design Cross-sectional study. Setting Towns of Sarajevo, Foca, Rogatica, and Pale in Bosnia and Herzegovina. Participants 300 community-dwelling older adults and 146 nursing home residents. Comprehensive Geriatric multidimensional assessment (CGA) was carried out to evaluate general health, functional, and cognitive capabilities. Nutritional status and undernutrition risk were assessed by Mini Nutritional Assessment (MNA) and Seniors in the Community: risk evaluation for eating and nutrition, version II (SCREEN II). HGS was measured with a Smedley dynamometer. Results According to the classification of nutritional status by MNA, 42% of community-dwelling men and 39% of community-dwelling women were at undernutrition risk. The undernutrition risk was significantly higher among nursing home residing men (89%) and women (78%) (p < 0.001). When nutritional status was assessed by SCREEN II, 100% on nursing home residents, 86% of community-dwelling men and 80% of women were identified as having a high risk for undernutrition. Per MNA, HGS cut-off thresholds were 23.50 kgF (65–74 years) and 19.50 kgF (≥75 years) for men; 15.50 kgF (65–74 years) and 13.50 kgF (≥75 years) for women. Per SCREEN II, cut-points were 28.50 kgF (65–74 years) and 24.50 kgF (≥75 years) for men; 24.50 kgF (65–74 years), 19.50 kgF (≥75 years for women). Conclusion HGS can be a useful instrument to identify undernutrition risk among the elderly patients. This study provides threshold for men and women older than 65 years of age in Bosnia and Herzegovina.

Since the creation of football fan groups, music and fan practices have been inseparably linked everywhere in the world. This paper will highlight the importance of punk music and other content that personify this specific urban subculture for a particular group of Gravediggers, respectively fans of JSD Partizan. The research was inspired by the appearance of punk rock band Grupa JNA (JNA Group), whose music is solely dedicated to Partizan and Gravediggers, but also to the already developed tradition of fanzine making and graffiti drawing that has flourished over the past few years, thanks primarily to the multimedia group Grobarski Trash Romanticism. We will try to find an answer to how punk as an idea and practice fits into the abstract idea of Partizan as something that so tightly connects a large number of individuals and again among them evokes an unfamiliar “sublime emotion”, unknown to non-fans.

The effect of pH and initial concentration on the removal of Cu(II) and Ni(II) ions from their monocomponent and two-component aqueous solutions using Na2CO3 as a chemical precipitation agent was investigated in this paper. Monocomponent aqueous solutions  of Cu(II) and Ni(II)  ions with their initial concentrations of 50 and 500 mg/L and two-component aqueous solution with initial concentration of 500 mg/L were prepared. The precipitation was carried out by batch method at room temperature by stirring the solution at 300 rpm for 5 minutes, resulting in the formation of precipitates. The resulting precipitate was separated by filtration from the solution. The experiment proved that Na2CO3 is a good agent for removing Cu(II) and Ni(II) ions from their monocomponent water solutions of 50 and 500 mg/L concentration and two-component water solution with initial concentration of each metal 500 mg/L. The percentage of Cu(II) removal was higher at lower pH values compared to Ni(II) removal.

The phenomenon of the increasing number of ageing people in the world is arguably the most significant economic, health and social challenge that we face today. Additionally, one of the major epidemiologic trends of current times is the increase in chronic and degenerative diseases. This paper tries to deliver a more up to date overview of chronic diseases and other limitations associated with old age and provide a more detailed outlook on the research that has gone into this field. First, challenges for seniors, including chronic diseases and other limitations associated with old age, are specified. Second, a review of seniors’ needs and concerns is performed. Finally, solutions that can improve seniors’ quality of life are discussed. Publications obtained from the following databases are used in this scoping review: Web of Science, PubMed, and Science Direct. Four independent reviewers screened the identified records and selected relevant publications published from 2010 to 2017. A total of 1916 publications were selected. In all, 52 papers were selected based on abstract content. For further processing, 21 full papers were screened.” The results indicate disabilities as a major problem associated with seniors’ activities of daily living dependence. We founded seven categories of different conditions - psychological problems, difficulties in mobility, poor cognitive function, falls and incidents, wounds and injuries, undernutrition, and communication problems. In order to minimize ageing consequences, some areas require more attention, such as education and training; technological tools; government support and welfare systems; early diagnosis of undernutrition, cognitive impairment, and other diseases; communication solutions; mobility solutions; and social contributions. This scoping review supports the view on chronic diseases in old age as a complex issue. To prevent the consequences of chronic diseases and other limitations associated with old age related problems demands multicomponent interventions. Early recognition of problems leading to disability and activities of daily living (ADL) dependence should be one of essential components of such interventions.

This article describes the process of competence-based curriculum development in nursing education at Western Balkan (WB) universities. Nursing education in the WB has been noncompliant with the standard educational approaches of the European Union's directive on regulated professions. The overall aim of the TEMPUS project "Competency-Based Curriculum Reform in Nursing and Caring in Western Balkan Universities" was to bring curricular reform for bachelor's nursing education in the WB region in line with competence-based education and professional standards to demonstrate compliance with all member countries of the European Union.

Automated detection of asphalt pavement distresses is a very popular computer vision and image processing problem. In recent years, automated detection is an essential part of every pavement management system, since it allows very fast detection of distresses on the road. This is important because timely detection can prevent many road accidents, and hence it has potential to save lives. In this paper, we presented a new unsupervised image processing method for segmentation of the most common road distresses-pavement cracks. The method first performs slicing of an image into M×N sub-images, and then removes sub-images without cracks based on empirically defined threshold. Analysis is then carried out only on a small number of sub-images, which significantly reduces computation time. Then, a series of images processing tasks are performed to select only pixels with pavement cracks. The method is suitable as a pre-processing step in a number of computer vision tasks, and can provide rough estimation of damaged area in an image.

Visual impairment severely constraints the ability to independently conduct many everyday tasks that we usually do not consider challenging. Although some types of visual impairment can be treated efficiently there is still a considerable number of visually impaired persons, especially among aging population, which depend on help of others or assistive technology to sustain their life quality. Visually impaired person cannot perceive the full extent of surrounding information due to the lack of visual details. However great progress can be achieved if surrounding information can be somehow visually transformed to the subset of visual information that visually impaired person can perceive. To certain extent every impairment has individual characteristics, as different individuals may better respond to different subsets of visual information. Thus any assistive solution aiming to visually transform surrounding information to accommodate broad range of impairment conditions must be personalized in order to be effective. Virtual reality enables individuals to experience imaginary surroundings by tricking their visual senses and such virtual surroundings can be personalized to any extent desired. We use virtual reality, image processing, and RFID to create a test setup able to simulate visual impairment and visually transformed surroundings suitable for visual Impairment studies. The test setup enables gathering information and conducting studies on both healthy and visually impaired individuals in a controlled environment enabling reliable assistive technology development and testing.

Visually impaired person might find it very difficult to locate an object that has been even slightly misplaced from its usual position. Unfortunately this is very common situation in a shared environment where multiple individuals can affect object’s position and where visually impaired person cannot rely on object’s position remaining unchanged since the last interaction with the object. In order to independently localize the object of its interest visually impaired person must rely on assistive technology. It is yet very unlikely that any single wearable assistive device will encompass the whole range of object localization scenarios and be universally adoptable to a broad range of environments. In this paper we propose indoors test setup for visually impaired persons by creating RFID based assistive environment – Visual Impairment Friendly RFID Room. The test setup can be used to evaluate RFID object localization and its use by visually impaired persons.
