AbstractAdditive manufacturing (AM) is a manufacturing process that allows for the creation of a physical object from a digital model. Additive manufacturing has a number of advantages over the conventional methods, inter alia the production of very complex machinery components, and a lower consumption of raw materials. Thanks to these advantages, the technology has been booming recently. The paper compares the advantages and disadvantages of additive technologies in the context of environmental impacts using Life Cycle Assessment (LCA). The paper describes the most important aspects of additive manufacturing, reviews the basic principles and phases of LCA method, including its application in AM, and outlines selected publications dealing with LCA and additive technologies. In conclusion, we recommend the most suitable methodologies to assess environmental impacts of additive technologies. To be specific, LCA is suitable to assess AM as for the material and energy flows, and in general, research in this field is considered highly promising.

Full textAbstract:
Multidimensional scaling was developed by psychometricians, namely R. N. Shepard (1962) and J. B. Kruskal (1964). Its purpose is to deduce indirectly the dimensions a respondent uses to evaluate alternatives. The reason for using the indirect approach is that, in many cases, the attributes may be unknown and respondents may be unable or unwilling to represent their reasons accurately. As already mentioned, multidimensional scaling requires an object-by-object similarity matrix as an input.
Initially popularized, however, multidimensional scaling relies on judged similarity. That is, respondents indicate how similar pairs of objects are directly rated (e.g. on a 1–10 scale). This can be a burdensome task since for p objects p(p-1)/2judgments are needed. Still, the use of similarity judgments is relatively easy for respondents, especially when they cannot or do not want to reveal the basis for their opinion.
The results of multidimensional scaling depend on (a) the sample chosen to judge similarity and (b) the objects whose similarity is judged and the quality of input data. Multidimensional scaling derives dimensions that appear to be used by those rating a particular set of objects.
The basic type of multidimensional scaling involves deducing graphical models of alternatives (e.g. brands) alone (simple space) from similarity data.
Some early applications of multidimensional scaling accepted apparent dimensions as “truth” without question or validation, which often proved to be disastrous. It is advisable to use multidimensional scaling as a generator of hypotheses rather than as a final model of the market. Any important result should be confirmed on a separate sample with a separate method, such as direct questioning, before the results are given too much credence.
Multidimensional scaling generates a configuration in which the relative positions of the brands are unique. The picture can be changed by several operations without changing the relationship among the interpoint distance in some of the algorithms (assuming the Euclidean distance is used, which it almost always is).
A major problem in data collection is the burden on respondents as the number of alternatives increases (e.g. 20 alternatives require 190 pairs). However, if respondents are “homogeneous”, it is possible to have different subjects rate a different pair.

Abstract Introduction In the last three decades, minimally invasive surgery (MIS) has been widely used in pediatric surgery. Meta-analyses (MAs) showed that studies comparing minimally invasive with the corresponding open operations are available only for selected procedures. We evaluated all available MAs comparing MIS with the corresponding open procedure in pediatric surgery. Materials and Methods A literature search was performed on all MAs listed on PubMed. All analyses published in English, comparing pediatric minimally invasive with the corresponding open procedures, were included. End points were advantages and disadvantages of MIS. Results of 43 manuscripts were included. MAs evaluating the minimally invasive with the corresponding open procedures were available for 11 visceral, 4 urologic, and 3 thoracoscopic types of procedures. Studies included 34 randomized controlled trials. In 77% of MAs, at least one advantage of MIS was identified. The most common advantages of MIS were a shorter hospital stay in 20, a shorter time to feeding in 11, and a lower complication rate in 7 MAs. In 53% of MAs, at least one disadvantage of MIS was found. The most common disadvantages were longer operation duration in 16, a higher recurrence rate of diaphragmatic hernia in 4, and gastroesophageal reflux in 2 MAs. A lower native liver survival rate after laparoscopic Kasai-portoenterostomy was reported in one MA. Conclusion In the available MAs, the advantages of MIS seem to outnumber the disadvantages. However, for some types of procedures, MIS may have considerable disadvantages. More randomized controlled trials are required to confirm the advantage of MIS for most procedures.

Full textAbstract:
The existence of contact angle hysteresis – the difference between the values of the advancing and receding contact angles – is evident in nature (e.g. sticking of rain drops to car windscreens and window panes) and many industrial processes (e.g. surface coating, spraying, and dyeing of fabrics). This phenomenon is often viewed as a nuisance, but it is advantageous in many processes including dip and spin coating, spraying, and painting. With the early theoretical framework of Thomas Young, Robert Wenzel, and A. B. D. Cassie and S. Baxter, describing the wettability of solid surfaces and by extension contact angle, contact angle hysteresis has been deeply investigated. We review here the various ways of measuring contact angle and, consequently, contact angle hysteresis as well as related theoretical models. The successes and limitations of these models are highlighted. We conclude with the advantages and disadvantages of contact angle hysteresis whose presence in many processes is often considered as a nuisance, especially when "coffee stain" forms from the evaporation of a volatile liquid drop containing nonvolatile components.

AbstractIn terms of monitoring the material and volume flow of pipe conveyors, the conveyor is considered to be a volumetric machine that does not have a "self-defence" function - in most cases, material needs to be dosed and monitored in the critical parts of the conveyor for smooth transportation and quick detection of deficiencies and errors. Appropriate attachment of the material flow sensor to the pipe conveyor structure plays an important role for efficient material monitoring on the pipe conveyor belt. The paper specifies and subsequently analyzes selected methods of mounting an optical material flow monitor - the Bulkscan LMS511, based on the ratio index method by analyzing the advantages and disadvantages of individual variants. The optimal variant is modelled in the PTC Creo Parametric program and the estimated costs for its implementation are evaluated.

The influence of local ground conditions on the parameters of seismic vibrations is the subject of study in seismic microzonation. This section of engineering seismology underwent radical changes at the end of the last century. The Commission on Seismic Safety of the National Institute of Building Sciences of the United States, as part of the implementation of the National Earthquake Damage Reduction Program, developed new NEHRP Recommendations, which are significantly different from all that has been used in the world practice of anti-seismic construction. The main provisions of this NEHRP classification have been adopted in many national building codes, including Eurocode 8 and Kazakhstan's seismic regulations. One of the essential features of the classification is the use of the average values of the velocities of transverse waves and the densities of the ground thickness with a thickness of 30 meters. In Russia, the provisions of the NEHRP norms have not yet been properly developed. Currently, the issue of extending the norms of Kazakhstan to the entire territory of the CIS countries is being considered. For this reason, the article examines in detail both the advantages and disadvantages of the NEHRP Recommendations in order to extract useful experience and adapt to the realities of Russian anti-seismic construction. In particular, the error in the representation of the parameters of the soil mass by average values is shown. The ways of overcoming the identified shortcomings of the description of the soil mass with the help of model representations are outlined

AbstractThere have been some hindrances in the process of programming learning. An adaptive learning system, such as ELaC, Java Guide, and Java Grader provides an adaptable learning content that can accommodate the learning styles as well as preferences of each learning individual. Moreover, an adaptive learning system can help students of different capabilities in learning programming. This study examined the outcomes of the implementation of an adaptive learning system in programming learning, as well as some finding results that were conducted according to the Systematic Literature Review framework. The research questions of this research were: problems faced during learning of programming as a background of system development, advantages and disadvantages of the system characteristics, technology, features, and effectiveness of the developed adaptive learning system. This research produced concepts that are summed up upon the related resources. The results of this study summarized whether the use of adaptive learning systems in learning programming could overcome the problems encountered during the learning process.

The paper presents the contemporary displacement measurement systems used in geotechnical laboratories during the determination of soil precise mechanical parameters, e.g., the shear modules G: initial and in the range of small and very small strains. In the laboratory, researchers use standard sensors for measuring deformation, pressure, and force as well as modern measuring systems such as linear variable differential transformers (LVDT), proximity transducers (PT), magnetic encoder sensors with fiber Bragg grating (FBG), or methods based on laser or X-ray measurement. None of the measurements are universal and their use depends on the type of soil (cohesive, non-cohesive), its condition (loose or dense, stiff or very soft), and its characteristic properties (e.g., organic soil, swelling soil). This study points out the interesting equipment solutions and presents the guidelines for selecting appropriate methods of deformation measurement.

Full textAbstract:
recent evidence in natural and semi-natural settings has revealed a variety of left-right perceptual asymmetries among vertebrates. these include preferential use of the left or right visual hemifield during activities such as searching for food, agonistic responses, or escape from predators in animals as different as fish, amphibians, reptiles, birds, and mammals. there are obvious disadvantages in showing such directional asymmetries because relevant stimuli may be located to the animal's left or right at random; there is no a priori association between the meaning of a stimulus (e.g., its being a predator or a food item) and its being located to the animal's left or right. moreover, other organisms (e.g., predators) could exploit the predictability of behavior that arises from population-level lateral biases. it might be argued that lateralization of function enhances cognitive capacity and efficiency of the brain, thus counteracting the ecological disadvantages of lateral biases in behavior. however, such an increase in brain efficiency could be obtained by each individual being lateralized without any need to align the direction of the asymmetry in the majority of the individuals of the population. here we argue that the alignment of the direction of behavioral asymmetries at the population level arises as an “evolutionarily stable strategy” under “social” pressures occurring when individually asymmetrical organisms must coordinate their behavior with the behavior of other asymmetrical organisms of the same or different species.

The soil seed bank is the primary source of regeneration in wetlands and has different assessment methods that vary according to the objective of the study. We evaluated the seed bank composition using three methods: seedlings emergence (EME), seedlings emergence with submersion trays in water (SUB) and screening and counting seeds (COU), and finally, we evaluated the applicability of COU to assess seed predation. The abundance and species richness were evaluated for two years at the end of the flood and dry seasons, in the Brazilian Pantanal. The abundance and species richness differed significantly between methods and seasons. The COU method showed the highest richness (84) and abundance (95.023) followed by EME and SUB. The SUB method reflected only the aquatic community. In the flood season, EME and COU methods showed similar species composition. There were no differences between COU and EME + SUB. The main advantage of COU method was the possibility to assess the seed predation, and we detected that Croton trinitatis had 32% of predated seeds. We consider that wetland ecosystems can be sampled by both methods COU and EME + SUB; however, the complete method that can be used for different purposes is COU, also, must be considered the infrastructure and objective of each study.

Abstract OBJECTIVE: To assess the advantages and disadvantages of the retrosigmoid intradural suprameatal approach by studying the microsurgical anatomy. This study was performed primarily to assess the advantages of the retrosigmoid intradural suprameatal approach by measuring the amount of increased exposure it provides for lesions of the cerebellopontine and petroclival region as well as to identify the disadvantages of the approach. METHODS: Twenty sides of 10 cadaver heads (embalmed and injected) were dissected under ×3 to ×40 magnification. A standard retrosigmoid craniotomy was made. The cerebellopontine cistern was entered to expose the neurovascular structures, and the internal auditory canal was opened by drilling the margin of the internal auditory meatus. After this, the suprameatal tubercle was drilled, followed by additional drilling to resect the petrous apex. The trigeminal root was mobilized completely after opening Meckel's cave. During drilling, care was taken to preserve the posterior and superior semicircular canals, petrosal sinus, and the internal carotid artery. RESULTS: The approach enhanced the exposure of the cerebellopontine cistern and Meckel's cave. There was an additional exposure of 10.7 ± 1.16 mm length of trigeminal nerve on the right side and an additional 10.7 ± 1.25 mm on the left. This helped to mobilize and further retract the trigeminal root. Although it facilitated the view of the neurovascular structures medial to the internal acoustic meatus, the depth of exposure did not vary much from a traditional retrosigmoid approach nor did it increase the angle of exposure or the visualization of the clivus and more medially located structures. CONCLUSION: This approach is suitable for lesions mainly in the posterior fossa with some extension into the middle fossa in the anterolateral direction. The key benefits of this approach are the length of trigeminal nerve exposure and the subsequent mobilization that improves visualization of the structures medial to the internal auditory canal, to the petrous apex, Meckel's cave, and the posterior end of the cavernous sinus.

Facing one of the most challenging pandemics for organizational modus operandi (COVID-19), organizations are struggling for operational and strategic support. The adoption of remote work (RW) is increasing. For economic reasons, competitive advantage, or even as a pandemic response (business continuity plan), RW is a domain worth further investigation. However, the literature lacks insight regarding RW adoption. A design science research methodology was adopted, including a systematic literature review to elicit RW advantages, disadvantages, challenges and driving forces, as well as their relation. To evaluate and demonstrate findings, 129 qualitative interviews were performed with RW professionals. In the end, 57 decision factors were elicited, and 16 relations were validated. The authors concluded that cost-reduction and flexibility to promote work–life balance is the most positive outputs, while communication and technical problems, as well as management issues, are what most concerns professionals. Moreover, positive relations are more recognized among professionals over negative ones.

Aim: Our review evaluated both the effects of single-occupancy patient rooms (SPRs) on patient outcomes for hospitalized adults and user opinion related to SPRs. Background: In 2006, a requirement for SPRs in hospitals was instituted in the United States. This systematic literature review evaluates research published since that time to evaluate the impact of SPRs. Methods: The review adheres to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Databases searched included MEDLINE, CINAHL, and Scopus. Supplemental searches were performed. We included studies reporting patient outcomes or user opinion related to SPRs. Appraisal was conducted using a dual appraisal system of evidence levels and methodological quality. Results: Forty-three studies qualified for appraisal. Three were excluded due to methodological quality (no appraisal score). One study was appraised for three individual outcomes (i.e., falls, infections, and user opinion). Eleven studies with low methodological quality scores were not included in the narrative synthesis. Overall, 87% of studies reported advantages associated with SPRs (some a combination of advantages and disadvantages or a combination of advantages and neutral results). Outcomes with the best evidence of benefit include communication, infection control, noise reduction/perceived sleep quality, and preference/perception. Conclusion: SPRs seem to result in more advantages than disadvantages. However, healthcare is a complex adaptive system, and decisions for 100% SPRs should be reviewed alongside related issues, such as necessary workflow modifications, unit configuration and other room layout decisions, patient populations, staffing models, and inherent trade-offs (e.g., the advantages of privacy compared to disadvantage of isolation).

Full textAbstract:
Recent research has emphasized the effectiveness of excuses in protecting the self from the implications of failures and transgressions. The disadvantages of excuses have been relatively neglected. The triangle model of responsibility provides a conceptual framework to analyze how excuses disengage the self from events and the conditions under which advantages and disadvantages accrue. On the disadvantage side, excuse-makers risk being seen as deceptive, self-absorbed, and ineffectual; they are viewed as unreliable social participants with flawed character These undesired consequences result when excuses are used in ways that lower credibility (e.g., fail to receive corroboration), lower goodwill (e.g., blamefailures on team members), and produce long-term disengagement (e.g., lead to failures to correct personal deficiencies). It is proposed that excuses are effective in the long run only if they balance short-term disengagement of the self and long-term engagement. Excuses are especially problematic when used to disengage the self from important, recurring tasks.

Research background: Teleworking is becoming more current and more used. It is an instrument that allows and supports globalization. The corona crisis increased its use even more. Teleworking has advantages, but also disadvantages which are perceived and evaluated by its users. With its more intense penetration, the users’ perception will become an important factor in the implementation. Teleworking has effects both on the whole economy and on the employees - it affects their social life, their working relations, and their flexibility. Purpose of the article: The purpose of the article is to identify the students’ perception of advantages and disadvantages of teleworking and the development of this perception from the year 2018 to the year 2020. In 2020, the data were collected during and after the corona crisis, and so we can observe its effects. Methods: We used an electronic survey to monitor students’ opinion on teleworking and processed the data by methods of descriptive statistics and more advanced statistical methods to obtain their characteristics. Findings & Value added: We found out that the perception of teleworking’s advantages and disadvantages didn’t change much from the year 2018 and stayed relatively stable in spite of the crisis. Only some effects of teleworking were considered by our respondents a little differently, e.g., the social aspects. Our findings may be used in addressing the perceived disadvantages of teleworking and supporting its advantages.

Full textAbstract:
The current studies investigated the processing and storage of lexical metaphors and metonyms by combining two existing methodologies from ambiguity research: counting the number of senses (as in e.g., Rodd, Gaskell, & Marslen-Wilson, 2002) and determining the relationship between those senses (as in e.g., Klepousniotou & Baum, 2007). We have called these two types of ambiguity ‘numerical polysemy’ and ‘relational polysemy’. Studies employing a lexical decision task (Experiment 1) and semantic categorization task (Experiment 2) compared processing of metaphorical and non-metaphorical words while controlling for number of senses. The effects of relational polysemy were investigated in more detail with a further lexical decision study (Experiment 3). Results showed a metaphor advantage and metonymy disadvantage which conflict with earlier findings of reverse patterns (e.g., Klepousniotou & Baum, 2007). The fact that both conventional lexical metaphors and metonyms can incur either processing advantages or disadvantages strongly suggests they are not inherently stored differently in the mental lexicon.

Purpose The purpose of this paper is to compare customer perceptions of hotel and peer-to-peer (e.g. Airbnb) accommodation advantages and disadvantages and examine their influence on customer satisfaction and repurchase intentions. The advantages of each accommodation type are conceptualized through perceived travel experience authenticity, whereas the disadvantages are evaluated through the risks associated with staying at each accommodation type, including product performance risk, time/convenience risk and safety and security risk. Design/methodology/approach A cross-sectional survey was designed and disseminated to gather the data necessary to fulfill the study objectives. A total of 391 usable responses were collected for a multi-group analysis of the structural model designed to test the proposed relationships. Findings The multi-group comparison revealed similarities between the peer-to-peer (Airbnb) and hotel guest structural models. Model testing revealed a strong positive relationship between satisfaction and repurchase intention. Perceived authenticity was identified as a statistically significant satisfaction predictor for both accommodation types. Time/convenience and product performance risks were found to be insignificant predictors of guest satisfaction, while safety and security risk appeared to be statistically significant only in the Airbnb sample. Research limitations/implications This study’s recruited sample represented a higher concentration of younger travelers, and, therefore, might only be generalized to the corresponding US traveler group population. Additionally, samples recruited via Amazon’s MTurk may be subject to self-selection bias as any other non-probability samples. Consequently, further research with a larger and more diverse sample is recommended. Practical implications It is recommended for both hotels and Airbnb to strengthen the authenticity of their accommodation offerings to provide a better guest experience and increase consumer satisfaction. Social implications To develop the authenticity component, Airbnb hosts and hotels may offer local experiences to their customers, where guests would be able to engage with the community and to see and feel how the city lives. Such partnerships may not only improve the traveler experiences but also support the local community and strengthen the ties between local businesses. Originality/value This study contributes to the literature by advancing understanding of peer-to-peer (Airbnb) versus hotel accommodation consumer preferences. This study offers relevant theoretical constructs for assessing both accommodation types’ advantages and disadvantages.

Purpose Little is known about actual price savings generated by cooperative purchasing and nonmonetary advantages, disadvantages and impediments for the cooperative purchasing of complex or high-risk purchases. This paper aims to explore these topics by studying joint purchasing of pacemakers in The Netherlands. Design/methodology/approach To evaluate the magnitude of price savings, data on individual and collective prices for 18 hospitals was analyzed. In addition, 16 interviews were carried out with representatives of hospitals that participated and did not participate in the joint purchase. Findings Based on quantitative and qualitative data, the authors found large differences in price savings which can be attributed to scale, but mostly to knowledge of the group and renewing a contract in a technology-driven and developing market. Limited product choice – because of an organization joining a cooperative – constrained the attractiveness of cooperative purchasing, as end users may have specific product preferences. The consideration of preferences of end users is important toward successful joint purchasing of complex items. Social implications The authors argue that price savings because of scale are about 7% for smaller organizations and 4% for larger organizations. For smaller organizations with low specific knowledge and capacity for buying complex products, economies of process and knowledge are more important reasons for joining a purchasing group than scale. For large organizations with high specific knowledge and capacity, scale is the most important reason. Originality/value This study combined qualitative and quantitative perspectives, using actual spend data, to investigate cooperative purchasing of high-risk or complex purchases. On the one hand, more insight into the magnitude and reasons for price savings is provided than in earlier literature. On the other hand, more insight is given in qualitative reasons for joining a group and challenges for cooperative purchasing of complex items.

Background:Good outcome has been reported with the laparoscopic approach in uncomplicated appendicitis, but a higher incidence of postoperative intraabdominal abscesses has been reported after laparoscopic appendectomy in complicated appendicitis. Objective was to study the efficacy of laparoscopic appendectomy.Methods: A Hospital based cross sectional study was carried out among of 302 patients. The study duration was from June 2004 to December 2006. Institutional Ethics Committee permission was obtained. Informed individual consent was taken. Out of 302 subjects, 236 underwent open appendectomy and 66 underwent laparoscopic appendectomy.Results:It was observed that in both the groups majority patients had retrocecal position of the appendix. The amount of blood loss, adjacent organ injury and duration of surgery were similar in both the groups. The difference in the incidence of wound infection in both groups was not found to be statistically significant. But the antibiotic use was significantly less in the LA group compared to OA group. It was found that time to resumptions of oral fees, duration of hospital stay and time to return to normal duties were significantly lesser in LA group compared to OA group. (p < 0.001). As per the cosmetic end result, majorities were satisfied in LA group and rated the surgery as excellent as compared to patients in OA group.Conclusions:Laparoscopic appendectomy was better than open appendectomy with respect to wound infection, tackling co-existing pathology, duration of hospital stay, earlier return to normal activity, excellent cosmetic end result, lesser use of antibiotics and earlier resumption of oral feeds.

Full textAbstract:
A trend is visible in the food literature showing an increasing number of publications on studies that incorporate some form of participant engagement, such as citizen science and community-based participatory research. This “participation trend” will inevitably affect the scientific field of food behaviour research. This new trend is however not only associated with advantages, and a critical reflection on both the advantages and disadvantages is needed. The current article is a position paper that contributes to the literature in two main ways. First, participation is still in the developmental stage. Many different forms, methods and definitions are used. By providing a structured overview of a variety of participatory methods derived from a focused search of the literature on food behaviour, we aim to clarify the relationships between the various forms of participation methods. Second, the involvement of citizens in research is increasingly calling for novel research methods (e.g., voluntary recruitment and active involvement), which may be accompanied by both advantages and disadvantages. We add to the literature by developing a framework that indicates the advantages and disadvantages of participatory methods in food behaviour research. Our study highlights the relevance of differentiating the goal of the researcher (efficiency versus engagement) and the role of citizens (collecting versus creating), thus implying a trade-off between cost-effectiveness and involvement, as well as between data richness and data quality. Our work is a first effort to create structure and guidance within a new area. Our efforts could be used in future research aimed at developing more extensive protocols and tools for the application of participation in research, thereby offering a controlled manner to ensure that research stays abreast of our changing society.

This paper presents a prototype of high speed brushless synchronous generators (BSG) design for the application in autonomous electric power generation systems (e.g., airplane power grid). Commonly used salient pole field of the main generator part of BSG was replaced with a prototype non-salient pole field. The main objective of the research is an investigation into the advantages and disadvantages of a cylindrical field of the main generator part of BSG over the original salient pole field. The design process of the prototype generator is presented with a focus on the electromagnetic and mechanical finite element method (FEM) analysis. The measurements of prototype and commercial BSG were conducted for the nominal speed of 8 krpm. The advantages and disadvantages of the proposed solution were established based on measurements in load and no-load conditions.

Abstract The use of the cell block in the cytology laboratory can be a routine procedure, having an important role in establishing the diagnosis and also in performing additional tests without the need for additional sampling of biological material. Numerous attempts have been made to modify and improve the cell block over the years, however, obtaining a cell block from a fluid biological product is a current challenge because lack of cell adhesion to a tissue remains the most common reason for dissatisfaction among cytopathologists. Although various methods for obtaining cell blocks have been proposed and described in the literature, it is noted that each of them has a disadvantage, in addition to advantages. Thus, in this study we propose a new method that eliminates in turn the disadvantages of other methods, obtaining an increase in cell densities, can apply additional testing applications, while minimizing laboratory costs.

Full textAbstract:
At the level of the gastrointestinal (GI) tract exists a consortium of living microorganisms like bacteria, fungi, protozoa and viruses, which represent the intestinal microbiota. This term, microbiota, comes from Greek, where ‘bios’ means ‘life’ and nowadays this is the right word to use, even if in the older literature the authors used the term microflora with the same meaning (Suchodolski, 2016). In order to describe the intestinal microbiota, there are more methods available, each of them having advantages and disadvantages. The aim of this literature study was to compare the data available regarding each method used for assessing the intestinal microbiota. Among the five methods available in the present to assess the intestinal microbiota, none of them is considered a gold standard. There are available cultural and non-cultural methods, each of them having the purpose to describe the intestinal resident bacterial populations. The most commonly used methods for characterization of the intestinal microbiota are represented by FISH- Fluorescence in situ hybridization, qPCR- quantitative real-time PCR, NGS- next-generation sequencing (e.g. 454- pyrosequencing, Illumine) and Metagenomics (shotgun sequencing of genomic DNA). In this review we made a comparison between the methods available for assessing the intestinal microbiota, showing that in the present there is not a golden standard for this and that the methods used have advantages and disadvantages.

Full textAbstract:
Time pressure is not usually seen as an advantage in front end innovation (subsequently referred to as “FEI”), but rather it is believed that ideas should be left to develop freely without a tight schedule. Instead of strictly formalized operations, creating ideas generally necessitates a certain level of freedom. The starting point for this research was to challenge this general view by imposing severe time pressure in FEI. The FEI process was reviewed from recognizing problems/creating ideas up until the selection of the best concept for further development. The research was executed as a qualitative in-depth investigation of a case. In the case, FEI took place over a three-week period, and the target for the FEI was to generate concepts of digital jewelry with business potential. The time pressure was seen as appropriate – with certain conditions – in FEI. The results also present the advantages and disadvantages of time pressure, combining it to the stress theory.

The article shows the problems with information flow in the case of bridge objects located on mining areas and the advantages of proper information management, e.g. the possibility of automatic monitoring of structures, improvement of safety, optimization of maintenance activities, cost reduction of damage removal and preventive actions, improvement of atmosphere for mining exploitation, improvement of the relationship between the manager of the bridge and the mine. Traditional model of managing bridge objects on mining areas has many disadvantages, which are discussed in this article. These disadvantages include among others: duplication of information about the object, lack of correlation in investments due to lack of information flow between bridge manager and mine, limited assessment possibilities of damage propagation on technical condition and construction resistance to mining influences.

Full textAbstract:
The UK student loans system is in crisis and the government plans to sell off student loans to corporate purchasers. Such loan sales disadvantage government, the taxpayer and student borrowers. The government should give student borrowers the ‘right to buy’ their own loans for the same price the government is prepared to sell those loans to corporate purchasers. If borrowers purchased their own loans, disadvantages of loan sales would transform into advantages. The ‘right to buy’ can fairly be extended to all borrowers, regardless of whether their loans are being sold; this is done by extending the ‘right to buy’ as a ‘right to reduce’ student loans. The ‘right to reduce’ also provides a solution to the problem of how to ‘deal with’ existing student debt. Because the ‘right to buy’ and the ‘right to reduce’ both follow government’s pricing for loan sales, they should be universally acceptable; moreover, government, taxpayers and borrowers would be better off.

Embedded passive components have certain advantages over surface mount components. These advantages include: Increased circuit density through real-estate savings, decreased end product weight, improved electrical properties through additional termination and filter layout options, shortening of electrical connections, increased product quality through elimination of incorrectly attached devices and improved reliability through the reduction of solder joints [1]. The disadvantages to their current implementation include a limited range of resistance values and broader resistance tolerances [2]. In this paper, we discuss an additive print technology for custom embedded resistors with tolerances better than 10% and feature size geometries below 1 mil (25 μm). This technology produces a wide range of custom resistance values on typical PCB substrate materials thus combatting the noted disadvantages. The resistors are printed in-line on the signal layer eliminating the need of additional PCB resistor layers. Manufacturing challenges and design rules of this process are discussed and the DC and RF performance extrapolated to 15 GHz are presented.

Full textAbstract:
A high water to cement ratio in concrete produces excessive porosity in the paste, thereby increasing the concrete’s susceptibility to sulfate attack and subsequent premature deterioration. Widely used as a building material, concrete experiences physical and chemical deterioration whose extent and nature may be determined by polarized light microscopy (PLM) and scanning electron microscopy (SEM). New software innovations allow exact image relocation in PLM and SEM, thereby producing complementary information which aids in analyst recognition and increases the effectiveness of each analytical technique.Although overlapping information may be derived using both PLM and SEM, each technique has inherent advantages and disadvantages which complement the other. The advantages of PLM include a color image, good low magnification resolution providing a bridge between macro/micro analysis, and the ability to distinguish polymorphs and materials of nearly identical composition (e.g., solid-solution series components). Disadvantages of PLM include limited high magnification potential, mineralogical identification based on the analyst’s knowledge of optics, and the need for photographic attachments.

Background Digital technologies are increasingly becoming an integral part of our daily routine and professional lives, and the healthcare field is no exception. Commercially available digital health technologies (DHTs – e.g. smartphones, smartwatches and apps) may hold significant potential in healthcare upon successful and constructive implementation. Literature on the topic is split between enthusiasm associated with potential benefits and concerns around privacy, reliability and overall effectiveness. However, little is known about what healthcare professionals (HCPs) have experienced so far with patients and what they perceive as the main advantages and disadvantages of adoption. This study therefore aims to investigate current perceptions of HCPs towards self-tracked health-related outputs from devices and apps available to the public. Methods Nine HCPs volunteered to take part in semi-structured interviews. Related data were thematically analysed, following a deductive approach with the construction of a framework based on expected themes from the relevant literature, and themes identified from the first two interviews. Findings The following main themes in relation to DHTs were identified and explored in detail: HCPs’ experience, knowledge and views; advantages and disadvantages; barriers towards healthcare implementation and potential solutions; future directions. While most participants were adopters of DHTs and held positive views about them, their overall experience with patients and the technology was limited. Potential reasons for this were explored, including factors such as time/resources; colleagues’ mindset; lack of evidence of effectiveness for practice; data security concerns. Conclusions The potential advantages of DHTs’ adoption in healthcare are substantial, e.g. patient autonomy, time/resources saving, health and behaviour change promotion, but are presently premature. Therefore, future research is warranted, focussing on addressing barriers, minimising disadvantages, and assessing the clinical value of commercially available DHTs.

In this discussion, I wish to outline the basic methods of analyzing the paleoenvironmental occurrence of palynomorphs and how this occurrence can be used in paleoecologic interpretation. (Unless otherwise stated, environment as used in this discussion means sedimentary environment.) Palynomorphs have advantages and disadvantages relative to using megafloral remains for the same purpose. Advantages of palynomorphs include their occurrence in large numbers extractable from small volumes of sediment; the usefulness of these large populations for statistical analysis; their occurrence in strata lacking megafossils; and the occurrence of palynomorphs of plants whose preservation potential as megafossils is poor (e.g., fungi, herbaceous plants, algae). Disadvantages of palynomorphs include potential for long-distance transport and reworking; uncertain affinities of many palynomorphs; and bias against zoophilous plants or plants whose pollen contains little sporopollenin (e.g., Populus). Palynomorphs do provide a complementary view of the vegetation which can be of great value if properly used, and whose potential should not be ignored. The best possible analysis would combine megafloral and palynological data at the same level of resolution. Variation of palynology with depositional environment, furthermore, can provide information on individual evolution, community evolution, biostratigraphy, and local variability within depositional environments as well as paleoecology.

Full textAbstract:
This paper deals with the problem of multiple inference in psychiatric research, an issue which arises whenever a researcher has to make more than one statistical inference in a single research study. It frequently arises in psychiatric research because of multivariate study designs, with subjects being measured on more than one dependent variable with the intention of studying differences between groups in mean scores. The disadvantages of the commonly adopted strategy of using multiple univariate tests (e.g. multiple t-tests) are outlined. Two broad strategies — Bonferroni-adjusted univariate tests and multivariate statistical analysis — are introduced. Their advantages and disadvantages are discussed in terms of their usefulness in confirmatory and exploratory research in psychiatry.
