As faculty performance and feedback analysis are essential to facilitate educators find effectual teaching and learning in order to better engage students in classes. This system aimed at holding teacher's accountability for their performance. The proposed system is based on technologies like PHP, JavaScript, HTML, XAMPP server, MYSQL, and Google APIs. This system will help the institution bureaucrats to write confidential appraisal report. The proposed system analysis the feedback class wise as well as individual faculty wise and provide the analysis in the form of Google charts.
The Virtual Collaborator - A Definition and Research Agenda
Authors: Siemon Dominik , Strohmann Timo , Robra-Bissantz Susanne
Published: September 2019

The interdisciplinary research endeavor of computer-supported collaborative work has already investigated information technology that supports collaboration. With the rise of artificial intelligence (AI), new forms of collaboration need to be considered that involve AI as an active partner within a collaborative setting. Theories and design guidelines that support collaboration, considering cognitive and social group effects, need to be revised when team members are not solely human anymore. Within this exploratory study, the authors aim to provide insights of team members on their conception of a so-called virtual collaborator. A study with 144 participants was carried out to provide valuable information about collaboration principles, conceptual implementations and requirements. The results indicate that the participants are indecisive about a precise conception but expect an ideal collaborator that rather should not work on relevant tasks or make vital decisions. Based on the results, the authors compose new research questions and possible experiment settings.
An Innovative Air Purification Method and Neural Network Algorithm Applied to Urban Streets
Authors: Boumahdi Meryeme , El Amrani Chaker , Denys Siegfried
Published: September 2019

In the present work, multiphysics modeling was used to investigate the feasibility of a photocatalysis-based outdoor air purifying solution that could be used in high polluted streets, especially street canyons. The article focuses on the use of a semi-active photocatalysis in the surfaces of the street as a solution to remove anthropogenic pollutants from the air. The solution is based on lamellae arranged horizontally on the wall of the street, coated with a photocatalyst (TiO2), lightened with UV light, with a dimension of 8 cm × 48 cm × 1 m. Fans were used in the system to create airflow. A high purification percentage was obtained. An artificial neural network (ANN) was used to predict the optimal purification method based on previous simulations, to design purification strategies considering the energy cost. The ANN was used to forecast the amount of purified with a feed-forward neural network and a backpropagation algorithm to train the model.
Algorithms for Real-Time Endoscopy Image Processing Pipeline in Clinical Decision Support Systems
Authors: Pozdeev Alexandr A. , Obukhova Nataliia A. , Motyko Alexandr A.
Published: September 2019

A set of algorithms, taking in account endoscopic image features and computational cost for real-time realization is proposed. A noise reduction algorithm is based on determining the level of detail in an image fragment. For fragments with a different level of detail, different noise reduction filters are used. The enhancement algorithm is based on nonlinear contrast enhancement which highlights the contrast of vessels relative to the background without significant noise stressing, which is one of the main disadvantages of nonlinear enhancement algorithms. The custom color correction algorithm takes into account user preferences and provides a mean error less than 0.5% for each color coordinate. The “mosaic” synthesis algorithm gets panoramic images of low detail images with a mean stitching error less than 0.75 pix. The software realization of algorithms allows processing 4K endoscopic video with a speed of about 30 fps.

Published: September 2019

Time processing is a challenging issue for content-based video retrieval systems, especially when the process of indexing, classifying and retrieving desired and relevant videos is from a huge database. A CBVR system called bounded coordinate of motion histogram (BCMH) has been implemented as a case study. The BCMH offline step requires a long time to complete the learning phase, and the online step falls short in addressing the real-time video processing. To overcome these drawbacks, this article presents a batch-oriented computing based on Apache Hadoop to improve the time processing for the offline step, and a real-time oriented computing based on Apache Storm topologies to achieve a real-time response for the online step. The proposed approach is tested on the HOLLYWOOD2 dataset and the obtained results demonstrate reliability and efficiency of the proposed method.
Iterative Interference Cancellation for Coded Filter Bank Multicarrier Systems
Authors: Assaf Mohammad Razk , Assimi Abdel-Nasser
Published: September 2019

Filter bank multicarrier is one of the candidates for future communication systems. Simple equalization methods cannot be directly applied due to the high interference from adjacent channels. In this article, the authors derive a soft-input/soft-output (SISO) equalizer based on the minimum mean square error (MMSE) criterion for the bit-interleaved coded system using a filter bank multi-carrier scheme with offset quadrature amplitude modulation (FBMC/OQAM). The authors use this SISO-MMSE equalizer in a turbo-equalization scheme for each sub-carrier. The difficulty in this implementation comes from the required processing delay per turbo-iteration due to the non-causal nature of the interference in this system. Therefore, the number of turbo-iterations is limited in order to limit the processing delay. The authors evaluate the performance of the proposed turbo-equalizer over the International Telecommunication Union (ITU) Vehicular B channel by mean of numerical simulations. The obtained results show the effectiveness of the proposed equalizer in term of signal-to-noise ratio (SNR) gain.
Emotion Recognition Approach Using Multilayer Perceptron Network and Motion Estimation
Authors: Berkane Mohamed , Belhouchette Kenza , Belhadef Hacene
Published: September 2019

Man-machine interaction is an interdisciplinary field of research that provides natural and multimodal ways of interaction between humans and computers. For this purpose, the computer must understand the emotional state of the person with whom it interacts. This article proposes a novel method for detecting and classify the basic emotions like sadness, joy, anger, fear, disgust, surprise, and interest that was introduced in previous works. As with all emotion recognition systems, the approach follows the basic steps, such as: facial detection and facial feature extraction. In these steps, the contribution is expressed by using strategic face points and interprets motions as action units extracted by the FACS system. The second contribution is at the level of the classification step, where two classifiers were used: Kohonen self-organizing maps (KSOM) and multilayer perceptron (MLP) in order to obtain the best results. The obtained results show that the recognition rate of basic emotions has improved, and the running time was minimized by reducing resource use.

Published: September 2019

The innovation for the recent agriculture tractors have been widely developed. These tractors are used to enhance the harvesting activities in way to lowering the labour cost. However, the current system of infield collection of oil palm fresh fruit bunches (FFB) by using mini-tractor-trailer (MTT) has its limitation. This MTT have poor traction on soft ground such as coastal and peat areas which give the limiting factors that prohibit the usage of any mini-tractor. Thus, the aim of this project is to fabricate a functioning prototype vehicle consist of two-wheel steering (2WS) and four-wheel steering (4WS) in measuring its performance of tractive effort and steering radius for usage in palm plantation. The machine configuration consists of main chassis, compartment to carry oil palm bunches, a mechanism for loading purposes, operator cabin, and associated hydraulic system. The laboratory test of performance evaluation were conducted to the developed vehicle. The results show that under 4WD mode, the turning radius of the vehicle was found to be 42.9% lesser if the 4WS mode is engaged. For 6WD with 4WS active, the turning radius was 46% lesser while turning for 42.2% lesser compared to 2WS. The slippage ranges are recorded between 8.5% to 22.5% where the slippage for the left wheel is negative as the left wheel rotates slower than the right wheel on the left turning of circular motion and vice versa. In addition, the vehicle design could be considered optimum as the measured tractive effort of the vehicle was found to be 32% of the vehicle gross weight. This is within the recommended tractive effort which is within a range of 30% to 36% of the suggested vehicle gross weight.

Absolute determination of gravity from free fall measurements using spectral analysis and least squares fit
Authors: Jeudy L M A
Published: September 2019

A practical and accurate (within 10- 4 nm) free fall formula is derived for the purpose of determining absolute gravity from free fall measurements using least squares fit. Small correcting terms for air resistance and Coriolis force (Eotvos effect) are taken
into account. A procedure using spectral analysis, least squares fit and variance-ratio significance F test eliminates non-random noise and computes gravity. The present study shows from real data that perturbing frequencies may create systematic errors up to 50 ~Gal. A method of computing an
average set of data is suggested and the problem of computer expenses is considered.

The diachrony of Dutchhoeven‘need’

This paper presents a diachronic investigation into the semantic and grammatical evolution of the Dutch negative polarity modal auxiliaryhoeven(‘need’). The study is corpus-based, working with representative samples of occurrences of the verb and of its predecessor, the (originally) full verbbehoeven(‘need’), from different stages of Dutch, from Old Dutch until today. It shows how, after the initiation of a tendency to auxiliarize inbehoevenin Early New Dutch (which largely ends again after that period), the short formhoevensplits off from the latter in that same time period and takes the lead as the auxiliary variant from then onwards. It also reveals, however, that in the course of New Dutchhoevenstarts to develop new autonomous uses, in a way comparable to what has happened in the other central modal auxiliaries in Dutch (a case of collective degrammaticalization). Moreover, it shows how, from its emergence onwards, this modal auxiliary develops a wide range of modal and related meanings in a very short time, no doubt due to a strive for (semantic) analogy with the other (and much older) central modals.

Published: September 2019

Abstract. Aerosol iodine isotopes are pivotal links in atmospheric circulation of iodine in both atmospheric and nuclear sciences, while their sources, temporal change and transport are still not well understood. This work presents the day-resolution temporal variation of iodine-129 (129I) and iodine-127 (127I) in aerosols from Xi'an, northwest China during 2017/2018. Both iodine isotopes have significant fluctuations with time, showing highest levels in winter, approximately two to three times higher than in other seasons, but the correlation between 129I and 127I reflects they have different sources. Aerosol 127I is found to be noticeably positively correlated with air quality index and five air pollutants. Enhanced fossil fuel combustion and inverse weather conditions can explain the increased concentrations and peaks of 127I in winter. The change of 129I confirms that source and level of 129I in the monsoonal region were alternatively dominated by the 129I-enriched East Asian winter monsoon and 129I-poor East Asian summer monsoon. The mean 129I/127I of (101 ± 124) × 10−10 provides an atmospheric background level for the purpose of nuclear environmental safety monitoring. This study suggests that locally discharged stable 127I and externally input 129I are likely involved into fine particles formation in urban air, shedding insights into long-range transport of air pollutants and iodine's role in particulate formation in urban atmosphere.
Incremental improvements of 2030 targets insufficient to achieve the
Paris Agreement goals

Published: September 2019

Abstract. Current global mitigation ambition as under the Paris Agreement as reflected in the National Determined Contributions (NDCs) up to 2030 is insufficient to achieve the Agreement's 1.5 °C long term temperature limit. As governments are preparing new and updated NDCs for 2020, the question as to how much collective improvement is achieved is a pivotal one for the credibility of the international climate regime. The recent Special Report of the Intergovernmental Panel of Climate Change on Global Warming of 1.5 °C has assessed a wide range of scenarios that achieve the 1.5 °C limit. Those pathways are characterized by a substantial increase in near-term action and total greenhouse gas (GHG) emission levels about 50 % lower than what is implied by current NDCs. Here we assess the outcomes of different scenarios of NDC updating that fall short of achieving this 1.5 °C benchmark. We find that incremental improvements in reduction targets even if achieved globally, are insufficient to align collective ambition with the goals of the Paris Agreement. We provide estimates for global mean temperature increase by 2100 for different incremental NDC update scenarios and illustrate climate impacts under those scenarios including for extreme temperature, long-term sea level rise and economic damages for the most vulnerable countries. Under the assumption of maintaining ambition as reflected in current NDCs up to 2100 and beyond, we project a reduction in the Gross Domestic Product (GDP) in tropical countries of about 50–60 % compared to a no-climate change scenario and long-term sea-level rise of close to 2 m in 2300. About half of these impacts can be avoided by limiting warming to 1.5 °C, or below. Scenarios of more incremental NDC improvements do not lead to comparable reductions in climate impacts. An increase in 2030 of the aggregated NDC ambition of big emitters by 33 % does not deliver more than about half the potential reduction in climate impacts compared to limiting warming to 1.5 °C. Our results underscore that a transformational increase in 2030 ambition is required to achieve the goals of the Paris Agreement and avoid the worst impacts of climate change.
River channel width controls blocking by slow-moving landslides in California's Franciscan mélange

Published: September 2019

Abstract. To explore the sensitivity of rivers to blocking from landslide
debris, we exploit two similar geomorphic settings in California's
Franciscan mélange where slow-moving landslides, often referred to as
earthflows, impinge on river channels with drainage areas that differ by a
factor of 30. Analysis of valley widths and river long profiles over
∼19 km of Alameda Creek (185 km2 drainage area) and
Arroyo Hondo (200 km2 drainage area) in central California shows a
very consistent picture in which earthflows that intersect these channels
force tens of meters of gravel aggradation for kilometers upstream, leading
to apparently long-lived sediment storage and channel burial at these sites.
In contrast, over a ∼30 km section of the Eel River (5547 km2 drainage area), there are no knickpoints or aggradation upstream
of locations where earthflows impinge on its channel. Hydraulic and
hydrologic data from United States Geological Survey (USGS) gages on Arroyo Hondo and the Eel River, combined
with measured size distributions of boulders input by landslides for both
locations, suggest that landslide derived boulders are not mobile at either
site during the largest floods (>2-year recurrence) with field-measured flow depths. We therefore argue that boulder transport capacity is
an unlikely explanation for the observed difference in sensitivity to
landslide inputs. At the same time, we find that earthflow fluxes per unit
channel width are nearly identical for Oak Ridge earthflow on Arroyo Hondo,
where evidence for blocking is clear, and for the Boulder Creek earthflow on
the Eel River, where evidence for blocking is absent. These observations
suggest that boulder supply is also an unlikely explanation for the observed
morphological differences along the two rivers. Instead, we argue that the
dramatically different sensitivity of the two locations to landslide
blocking is related to differences in channel width relative to typical
seasonal displacements of earthflows. A synthesis of seasonal earthflow
displacements in the Franciscan mélange shows that the channel width of
the Eel River is ∼5 times larger than the largest annual
seasonal displacement. In contrast, during wet winters, earthflows are
capable of crossing the entire channel width of Arroyo Hondo and Alameda
Creek. In support of this interpretation, satellite imagery shows that
immobile earthflow-derived boulders are generally confined to the edges of
the channel on the Eel River. By contrast, immobile earthflow-derived
boulders jam the entire channel on Arroyo Hondo. Our results imply that lower drainage area reaches of earthflow-dominated catchments may be particularly prone to blocking. By inhibiting the upstream
propagation of base-level signals, valley-blocking earthflows may therefore
promote the formation of so-called “relict topography”.
Hydrological signatures describing the translation of climate seasonality into streamflow seasonality
Authors: Gnann Sebastian J. , Howden Nicholas J. K. , Woods Ross A.
Published: September 2019

Abstract. Seasonality is ubiquitous in nature, and it is closely linked to water quality, ecology, hydrological extremes, and water resources management. Hydrological signatures aim at extracting relevant information about hydrological behaviour, and they can be used to better understand hydrological processes and to evaluate hydrological models. Commonly used seasonal hydro-climatological signatures consider climate or streamflow seasonality, but not how climate seasonality translates into streamflow seasonality. We propose and test hydrological signatures based on the attenuation of the seasonal climate input by a catchment. We approximate the seasonality in the input (precipitation minus potential evapotranspiration) and the output (streamflow) by sine waves. A catchment alters the input sine wave by reducing its amplitude and by shifting its phase. We use these quantities, the amplitude ratio and the phase shift, as seasonal hydrological signatures. We present analytical solutions describing the response of linear reservoirs to periodic forcing to interpret the seasonal signatures in terms of configurations of linear reservoirs. Using data from the UK and the US, we show that the seasonal signatures exhibit hydrologically interpretable patterns and that they are a function of both climate and catchment attributes. Wet, rather impermeable catchments hardly attenuate the seasonal climate input. Drier catchments, especially if underlain by a productive aquifer, strongly attenuate the input sine wave leading to phase shifts up to several months. Finally, we test whether two commonly used hydrological models (IHACRES, GR4J) can reproduce the observed ranges of seasonal signatures in the UK. The results show that the seasonal signatures can aid model building and evaluation.
Worldwide lake level trends and responses to background climate
variation
Authors: Kraemer Benjamin M. , Seimon Anton , Adrian Rita , McIntyre Peter B.
Published: September 2019

Abstract. Lakes provide many important benefits to society including drinking water, flood attenuation, nutrition, and recreation. Anthropogenic environmental changes may affect these benefits by altering lake water levels. However, background climate oscillations such as the El Nino Southern Oscillation, and the North Atlantic Oscillation can obscure long-term trends in water levels, creating uncertainty over the strength and ubiquity of anthropogenic effects on lakes. Here we account for the effects of background climate variation and test for long-term (1992–2019) trends in water levels in 117 globally-distributed large lakes using satellite altimetry data. On average, 27 % of water level variation in individual lakes was associated with background climate variation. The relative influence of specific axes of background climate variation on water levels varied substantially across and within regions. After removing the effects of background climate variation on water levels, long-term water level trend estimates were lower (+1.0 cm year−1) than calculated from raw water level data (+1.4 cm year−1). However, the trends became more statistically significant in 76 % of lakes after removing the effects of background climate variation (the median p-value of trends changed from 0.12 to 0.02). Thus, robust tests for long-term trends in lake water levels which may or may not be anthropogenic will require prior isolation and removal of the effects of background climate variation. Our findings suggest that background climate variation often masks long-term trends in environmental variables, but can be accounted for through more comprehensive statistical analyses.
Miocene basement exhumation in the Central Alps recorded by detrital garnet geochemistry in foreland basin deposits
Authors: Stutenbecker Laura , Tollan Peter M. E. , Madella Andrea , Lanari Pierre
Published: September 2019

Abstract. The Neogene evolution of the European Alps was characterized by the
exhumation of crystalline basement, the so-called external crystalline
massifs. Their exhumation presumably controlled the evolution of relief,
distribution of drainage networks, and generation of sediment in the Central
Alps. However, due to the absence of suitable proxies, the timing of their
surficial exposure and thus the initiation of sediment supply from these
areas are poorly constrained. The northern Alpine foreland basin preserves the Oligocene to Miocene
sedimentary record of tectonic and climatic adjustments in the hinterland.
This contribution analyses the provenance of 25 to 14 Myr old alluvial fan
deposits by means of detrital garnet chemistry. Unusually grossular- and
spessartine-rich garnet is found (1) to be a unique proxy for identifying
detritus from the external crystalline massifs and (2) to occur abundantly
in ca. 14 Myr old deposits of the foreland basin. In contrast to previous
assumptions, we therefore propose that the external massifs were already
exposed to the surface ca. 14 Myr ago.

Can gapping be embedded? Experimental evidence from Spanish
Authors: Bîlbîie Gabriela , de la Fuente Israel
Published: September 2019

This paper discusses the No Embedding Constraint, considered to be a strong syntactic constraint on gapping and a diagnostic for this ellipsis type. As shown by two acceptability judgments tasks in Spanish, the assumptions related to the No Embedding Constraint are not borne out by our experimental results. Embedded gapping is acceptable in Spanish, and seems to be governed by a (more general) semantic constraint. Specifically, some predicates embed more easily than others, confirming, on the one hand, the asymmetry between non-factive and factive predicates, and, on the other hand, the dichotomy between semi-factive and true factive predicates. Embedded gapping and embedded coordinated clauses in general are thus sensitive to the semantic class of the embedding predicate. We argue that our data on embedded gapping in Spanish constitute a challenge for any Small Conjunct Gapping approach (in terms of subclausal/low coordination) and give support to a Large Conjunct Gapping approach (in terms of clausal/high coordination). In this paper, we adopt a constructional fragment-based analysis of gapping, which treats non-embedded and embedded gapping uniformly. More generally, this paper suggests that gapping is more similar to other ellipsis types than has been traditionally assumed.

Aim of study: To determine the effects of white shrimp (Litopenaeus vannamei) and tilapia nilotica (Oreochromis niloticus var. Spring) in monoculture and co-culture on water quality variables and production in earthen ponds during dry and rainy seasons.Area of study: A shrimp farm (total area 20 ha) at Chiripa, San Blas Nayarit, Northwest coast of Mexico (21° 37' 34.53 " N; 105° 18' 16.31" W).Material and methods: Two production cycles were performed in a completely randomized design consisting of two treatments and three replications each during rainy season (September-December) and dry season (February-May). Shrimp was the main crop and tilapia the secondary species.Main results: White shrimp (10 org/m2) can be co-cultured with Nile tilapia at a stocking high density (4 org/m2), leading to improved water quality and better utilization of nutrients in dry season than in rainy season. However, the shrimp’ highest weight was recorded in the tilapia-shrimp co-culture ponds during rainy season due to higher water temperature and better quality of live food. The mean individual weight, biomass and survival of the shrimp, in co-culture ponds were greater than those of the shrimp monoculture, in the two seasons studied.Research highlights: There was a trend towards greater concentration of nutrients in the water of the monoculture ponds and, lower dissolved oxygen and higher BOD5 in co-culture ponds in the dry season than in the rainy season.

Published: September 2019

The micro-spectrometer Argus 1000 being in space continuously monitors the sources and sinks of the trace gases. It is commonly believed that among other gases CO_2 is the major contributor causing the greenhouse effect. Argus 1000 along its orbit gathers the valuable spectral data that can be analyzed and retrieved. In this paper we present the retrieval of CO_2 gas in the near infrared window 1580 to 1620 nm by using line-by-line code GENSPECT. The retrieved Argus 1000 space data taken over British Columbia on May 31, 2010 indicates an enhancement of CO_2 by about 30%.

New evidence builds upon the Student Engagement IndexTM and Teacher Engagement IndexTM research (Scott-Webber, Konyndyk, & French, 2019; Scott-Webber, Konyndyk, French, & French, 2018; Scott-Webber, Konyndyk, French, Lembke, & Kinney, 2017) determining post-occupancy answers to, “Can we demonstrate that the design of the built environment for grades 6–8 impacts student academic engagement levels post-occupancy?” The early studies used respondents from grades 9–12. This one is from users in grades 6–8 (‘alpha’ pilot). All studies were conducted in the USA as convenience samples. Engagement performance is a high predictor of student success across multiple domains and learning/work experiences. Specifically, “Research that shows that engagement, the time and energy students devote to educationally purposeful activities, is the best single predictor of their learning and personal development” (Anonymous, NSSE, 2010, p. 2), and thus our research focus. From both the students and educators perspectives, design of the built space impacts engagement performance (p < .0001).
Does the Fatigue Index Induced in Athlete’s Affect Static Balance?
Authors: Soslu Recep
Published: September 2019

Balance is the process of maintaining the body center of gravity vertically over the base of support and relies on rapid, continuous feedback and integration of afferent information coming from three sensory components, that is somatosensory, visual, and vestibular systems, resulting in smooth and coordinated neuromuscular actions. To investigate the effects of fatigue index on the static balance of sportsmen. A total of 51 male elite sportsmen from 4 different sports branches (Football players: 19, Volleyball players: 13, Skiers: 10 and Athletes: 9) participated in the study. The Wingate anaerobic power and capacity test was applied to induce fatigue. The Technobody isokinetic balance meter (Pro-Kin. CSMI) was used to measure pre- and post-fatigue static balance. There was a significant interaction between dependent (pre and post test balance) and independent (test statue and sport branches) variables were observed (F(63,1031.14) = 1.59, η2 = .07, p ˂ .05). Main effect results showed that pre-fatigue balance values were significantly different than post-fatigue balance values in all groups (F(1.14, 213.91) = 177.99, η2 = .49, p ˂ .05).Moreover, significant differences were identified between pre- and post-fatigue test results in sport branches (F(3.188) = 4.12, ƞ2 = .06, p < .05) and test statue (eyes open and closed) (F(3.188) = 3.32, ƞ2 = .05, p < .05). Bonferonni follow-up test indicated that there was a significant increase from footballers’ average static balance to the athletes’ average static balance (p ˂ .05). In test statue, pre fatigue eyes closed values were significantly different than post fatigue eyes opened values (p ˂ .05). Static balance training should be included in the training to be performed, fatigue static balance training should be performed in team and individual sports and the content of the training should be reorganized in line with the results obtained.

Uvod: Iako je plasiranje centralnog venskog katetera rutinska procedura koju izvode anesteziolozi, ono nosi određeni rizik od komplikacija. Jedna od komplikacija je malpozicija, odnosno neadekvatna pozicija katetera. Prikaz slučaja: Predstavljamo slučaj pacijentkinje koja je primljena u jedinicu intenzivne nege zbog povrede glave i povraćanja sveže krvi. Plasiran joj je centralni venski kateter kroz desnu unutrašnju jugularnu venu. Zbog hemodinamske nestabilnosti i potrebe za ordiniranjem tečnosti i krvi, nije odmah urađen RTG snimak grudnog koša radi procene položaja katetera. Nakon stabilizacije pacijentkinje, urađen je RTG snimak koji je pokazao da se vrh katetera ne nalazi u gornjoj šupljoj veni već u desnoj veni subklaviji. Zaključak: Ovaj slučaj je pokazao da vrh centralnog venskog katetera ne završi uvek u gornjoj šupljoj veni. Kada se nalazi u venskom sistemu, čak i kada nije u gornjoj šupljoj veni, može u urgentnim situacijama poslužiti za inicijalnu nadoknadu tečnosti i aplikovanje lekova, a po stabilizaciji pacijenta treba razmotriti repoziciju ili plasiranje novog katetera. Ključne reči: unutrašnja jugularna vena, vena subclavia, malprezentacija, venski kateter AUTORI SUMARY SRPSKI Introduction: Although placement of the central venous catheter is a routine procedure carried out by anesthesiologists, it carries a certain risk of complications. One of the complications is malposition, or inadequate catheter position. Case report: We present a case of the patient who was admitted to an intensive care unit due to head injury and blood vomiting. The central venous catheter was inserted through the right internal jugular vein. Due to haemodynamic instability and the need for fluid and blood infusion, a chest x-ray examination was not immediately performed to evaluate the position of the catheter. After the patient was stabilized, the test was performed and revealed that the tip of the catheter was not located in the superior vena cava but in the right subclavian vein. Conclusion: This case has shown that the misplacement of the central venous catheter tip is not unusual. Once in the venous system, even when it is not located in the superior vena cava, it can be used for initial fluid replacement and drug administration, and after the patient is stabilized, the repositioning or placement of a new catheter should be considered.

Background Mastectomy in male transgender patients is an important (and often the first) step toward physical manhood. At our department, mastectomies in transgender patients have been performed for several decades.

Methods Recorded data were collected and analyzed for all male transgender patients undergoing mastectomy over a period of 24 years at our department.

Results In total, 268 gender-reassigning mastectomies were performed. Several different mastectomy techniques (areolar incision, n=172; sub-mammary incision, n=96) were used according to patients’ habitus and breast features. Corresponding to algorithms presented in the current literature, certain breast qualities were matched with a particular mastectomy technique. Overall, small breasts with marginal ptosis and good skin elasticity allowed small areolar incisions as a method of access for glandular removal. In contrast, large breasts and those with heavy ptosis or poor skin elasticity often required larger incisions for breast amputation. The secondary correction rate (38%) was high for gender reassignment mastectomy, as is also reflected by data in the current literature. Secondary correction frequently involved revision of chest wall recontouring, suggesting inadequate removal of the mammary tissue, as well as scar revision, which may reflect intense traction during wound healing (36%). Secondary corrections were performed more often after using small areolar incision techniques (48%) than after using large sub-mammary incisions (21%).

Conclusions Choosing the suitable mastectomy technique for each patient requires careful individual evaluation of breast features such as size, degree of ptosis, and skin elasticity in order to maximize patient satisfaction and minimize secondary revisions.

Background The mandible is an important structure that is located in the lower third of the face. Large mandibular defects after tumor resection cause loss of its function. This study assessed the outcomes and tumor recurrence after immediate mandibular reconstruction using a free fibula osteocutaneous flap following radical resection of ameloblastoma.

Methods This is a retrospective non-randomized study of outcomes and tumor recurrence of all patients diagnosed with mandibular ameloblastoma from August 1997 until August 2017 (20 years) requiring free fibula osteocutaneous flap reconstruction at a single institution. The patients were identified through an electronic operative database; subsequently, their medical records and photo documentation were retrieved.

Results Twenty-seven patients were included in this study. Eighteen patients were male, while nine were female. The majority of the patients (48.1%) were in their third decade of life when they were diagnosed with ameloblastoma. All of them underwent radical resection of the tumor with a surgical margin of 2 cm (hemimandibulectomy in cases with a large tumor) and immediate mandibular reconstruction with a free fibula osteocutaneous flap. Two patients required revision of a vascular anastomosis due to venous thrombosis postoperatively, while one patient developed a flap recipient site infection. The flap success rate was 100%. There was no tumor recurrence during a mean follow-up period of 5.6 years.

Conclusions Mandibular ameloblastoma should be treated with segmental mandibulectomy (with a surgical margin of 2 cm) to reduce the risk of recurrence. Subsequent mandibular and adjacent soft tissue defects should be reconstructed immediately with a free fibula osteocutaneous flap.

Background Various surgical management methods have been proposed for ischial sore reconstruction, yet it has the highest recurrence rate of all pressure ulcer types. A novel approach combining the advantages of a perforator-based fasciocutaneous flap and a muscle flap is expected to resolve the disadvantages of previously introduced surgical methods.

Methods Fifteen patients with ischial pressure ulcers with chronic osteomyelitis or bursitis, who underwent reconstructive procedures with an inferior gluteal artery perforator (IGAP) fasciocutaneous flap and a split inferior gluteus maximus muscle flap from January 2011 to June 2016, were analyzed retrospectively. The split muscle flap was rotated to obliterate the deep ischial defect, managing the osteomyelitis or bursitis, and the IGAP fasciocutaneous flap was rotated or advanced to cover the superficial layer. The patients’ age, sex, presence of bursitis or osteomyelitis, surgical details, complications, follow-up period, and ischial sore recurrence were reviewed.

Results All ischial pressure ulcers were successfully reconstructed without any flap loss. The mean duration of follow-up was 12.9 months (range, 3–35 months). Of 15 patients, one had a recurrent ulcer 10 months postoperatively, which was repaired by re-advancing the previously elevated fasciocutaneous flap.

Conclusions The dual-flap procedure with an IGAP fasciocutaneous flap and split inferior gluteus maximus muscle flap for ischial pressure ulcer reconstruction is a useful method that combines the useful characteristics of perforator and muscle flaps, providing thick dual padding with sufficient vascularization while minimizing donor morbidity and vascular pedicle injury.

Background The objectives of this study were to design polycaprolactone nanofibers with a radial pattern using a modified electrospinning method and to evaluate the effect of radial nanofiber deposition on mechanical and biological properties compared to non-patterned samples.

Methods Radially patterned polycaprolactone nanofibers were prepared with a modified electrospinning method and compared with randomly deposited nanofibers. The surface morphology of samples was observed under scanning electron microscopy (SEM). The tensile properties of nanofibrous mats were measured using a tabletop uniaxial testing machine. Fluorescence-stained human bone marrow stem cells were placed along the perimeter of the radially patterned and randomly deposited. Their migration toward the center was observed on days 1, 4, and 7, and quantitatively measured using ImageJ software.

Results Overall, there were no statistically significant differences in mechanical properties between the two types of polycaprolactone nanofibrous mats. SEM images of the obtained samples suggested that the directionality of the nanofibers was toward the central area, regardless of where the nanofibers were located throughout the entire sample. Florescence images showed stronger fluorescence inside the circle in radially aligned nanofibers, with significant differences on days 4 and 7, indicating that migration was quicker along radially aligned nanofibers than along randomly deposited nanofibers.

Conclusions In this study, we successfully used modified electrospinning to fabricate radially aligned nanofibers with similar mechanical properties to those of conventional randomly aligned nanofibers. In addition, we observed faster migration along radially aligned nanofibers than along randomly deposited nanofibers. Collectively, the radially aligned nanofibers may have the potential for tissue regeneration in combination with stem cells.
