Attachment, regulation, and competency framework in mental health services with youth experiencing homelessness: A qualitative study of clinician views

AimsAims were to 1) explore mental health clinicians’ experiences receiving training in the Attachment, Regulation, and Competency (ARC) framework, and 2) examine clinicians’ views of their own use of ARC when providing mental health services for youth experiencing homelessness (YEH). MethodParticipants included 10 clinicians with experience providing mental health services to YEH. Researchers collected data using a semi-structured interview guide and coded data following thematic analysis methods. ResultsClinicians described their ARC training and subsequent readiness to deliver ARC-informed services and provided feedback on how training could be improved. When reflecting on their use of ARC, they described the framework as inclusive, shared challenges and solutions to applying ARC in their work, and detailed how they promote attachment, regulation, and competency with YEH using this model. ConclusionClinicians emphasized the need for flexibility and creativity when using ARC-informed interventions in mental health care for YEH.

Improvement of technology of variable chemical composition layer formation on the product surface

The possibility of forming on the surface of the product by arc deposition a layer with variable chemical composition with a predefined distribution of properties is considered. With the arc deposition of a layer of variable chemical composition, there are some difficulties for obtaining its high quality realization caused by the influence of the molten base metal of the welding pool on the distribution of chemical elements along the length of the deposited layer. When surfacing such layers with the use of ceramic alloying fluxes, there is a limit on the number of alloys that are introduced into the welding pool from the flux without impairing of the surfacing quality. This problem is solved through the use of arc surfacing with a tape electrode, which provides a minimum share of the base metal in the weld, as well as the inclusion of arc spraying technology during the formation of the working layer by arc surfacing, which makes it possible to introduce additional alloying elements into the weld pool. Currently, the process of arc spraying is carried out at equal feed rates of the electrodes in the metallizer. The electrodes have the same chemical composition and the electric arc is supplied with direct or alternating current. A variant of the metallizer design is proposed, which allows controlling the chemical composition of the deposited metal through the use of two electrodes of different chemical composition, while the metallizer has the ability to separately control the feed rates of these electrodes. By adjusting the ratio of the feed rates, while ensuring at a constant level the total mass rate of their melting (feed), one can change the chemical composition of the sprayed layer. The paper presents schemes for the implementation of the metal arc spraying process of a layer with variable chemical composition

INFORMATION DIFFERENCES OF CORATAL ANATOMI MAGNETIC RESONANCE IMAGE ANTHOMY MAGNETIC RESONANCE (MRCP) IN T2 FRFSE (FAST RECOVERY FAST SPIN ECHO) SELECTION BETWEEN USE OF ARC WITH NO ARC

Background : MRCP is a biliary tract and pancreatic duct imaging technique, one technique that uses a breath hold. The technique speeds up acquisition time by using the Parallel Imaging ARC method so that it reduces the encoding phase on K-Space to reduce breath hold. Therefore it can increase image sharpness and reduce blurring image. The purpose of this study was to determine the differences in anatomical image information between using ARC and without using ARC on MRCP examination of coronal T2 FRFSE sequence pieces and to find better anatomical image information between using ARC and without using ARC on MRCP examination of FRFSE T2 sequences. Method : The type of research conducted by the author is quantitative research with an experimental approach. This research was carried out with 1.5 T MRI at Santo Borromeus Hospital, Bandung. Data in the form of 16 MRCP anatomical images of coronal chunks of T2 FRFSE sequences from 8 patients using ARC and without using ARC. Scores on the image are carried out in the gallbladder, cystic duct, common hepatic duct, intra-hepatic duct, common bile duct and pancreatic duct using questionnaires to 3 radiology specialists (respondents). The results of the respondents were analyzed using Wilcoxon statistical test to find out the differences in MRCP anatomical information on FR2E T2 sequences between using ARC and without using ARC and to find better anatomical image information from the two sequences seen from the mean rank value. Result : The results showed that there were significant differences in MRCP anatomical image information of coronal T2 FRFSE sequences between the use of ARC and without using ARC with a significance value of <0.05. Based on mean rank results, MRCP information on T2 FRFSE sequence coronal pieces using ARC has a mean rank value of 4.50 while MRCP T2 FRFSE coronal sequence sequences using without ARC have a mean rank value of 0.00, meaning FRFSE T2 sequences using ARC have better image information than FRFSE T2 without using ARC. Conclusion : Suggestion, the parallel imaging technique of the ARC method was applied on the MRCP examination of T2 FRFSE sequences and the data from this study could be used as baseline data to add ARC as the operational standard of the MRCP examination procedure.

Tastant-Evoked Arc Expression in the Nucleus of the Solitary Tract and Nodose/Petrosal Ganglion of the Mouse Is Specific for Bitter Compounds.

Despite long and intense research, some fundamental questions regarding representation of taste information in the brain still remain unanswered. This might in part be due to shortcomings of the established methods that limit the researcher either to thorough characterization of few elements or to analyze the response of the entirety of neurons to only one stimulus. To overcome these restrictions, we evaluate the use of the immediate early gene Arc as a neuronal activity marker in the early neural structures of the taste pathway, the nodose/petrosal ganglion (NPG) and the nucleus of the solitary tract (NTS). Responses of NPG and NTS neurons were limited to substances that taste bitter to humans and are avoided by mice. Arc-expressing cells were concentrated in the rostromedial part of the dorsal NTS suggesting a role in gustatory processing. The use of Arc as a neuronal activity marker has several advantages, primarily the possibility to analyze the response of large numbers of neurons while using more than one stimulus makes Arc an interesting new tool for research in the early stages of taste processing.

Acute Risk Change: An Innovative Measure of Operative Adverse Events and Perioperative Team Performance

Cardiac surgical risk models predict mortality preoperatively, whereas intensive care unit (ICU) models predict mortality postoperatively. Finding a large difference between the 2 (an acute risk change [ARC]) may reflect an alteration in the status of the patient related to the surgery. An adverse ARC was associated with morbidity and mortality in an Australian population. The aims of this study were to validate ARC in a UK population and to investigate the possible mechanisms behind ARC. This was a retrospective case-control study. Single, high-volume cardiothoracic hospital. Data from 4,842 cardiac surgical patients were collected between 2013 and 2015. None. EuroSCORE was recalibrated to each preceding year's data. ARC was defined as postoperative minus preoperative percentage mortality risk. Association among ARC, morbidity, and mortality was tested. Cases with large adverse ARC (greater than +15%) were compared with cases with large favorable ARC (less than -10%) with regard to intraoperative adverse events, unmeasured patient risk factors, and postoperative events. Adverse ARC was associated with hospital mortality, ICU stay, ICU readmission, renal support, prolonged intubation and return to the operating room (p < 0.001). Intraoperative adverse events occurred in 23 of 33 patients with adverse ARC; however, only 2 of 17 patients with favorable ARC reported adverse events (p < 0.001). Unmeasured risk factors were present in 48% of patients in the adverse ARC group. ARC is a readily available and sensitive marker that correlates strongly with morbidity and mortality. The use of ARC in local and national quality monitoring could identify areas for improvement of the quality of cardiac surgical care.

RANCANGAN ALAT PEMOTONG PAVING KAPASITAS 275 POTONG/JAM DILENGKAPI PENGUKUR SUDUT

Implementation of a project there are three main aspects which is an indicator of the sustainability of cost, schedule and quality. The project succeeds when the time and cost of the implementation are as planned. One of them is paving installation project. The average paving cut process takes 90 seconds for 1 paving d using a cutting grinder. Disadvantages of cutting grinding is a long time, but it also causes dust and noisy sound, resulting from knife blades with paving. The current tool is not equipped with an angle meter, for cutting with a certain angle only forecasting only. The use of arcs manually takes a longer time.The purpose of this plan is to accelerate the process of cutting paving according to the shape and size of the Pav- ing cutting will be more efficient when equipped with angle measurement. The planning of this tool using a mechanical system, work by clamping the object to be cut and only one press for cutting 1 paving. The result of the planning of the paving cutter with angle engraver is ob- tained by the difference of cutting time for paved rectangular paved 15o, 30 °, 40 ° 45o each 81 seconds, 75 seconds, 75 seconds, 83 seconds time difference for paving rectangle with cut length 10cm and 20cm are respectively 66 seconds and 86 seconds while the time difference for paving the hexagon with a length of 160m and 22 cm is 72 seconds respectively and To sec. The average time required for each cutting ± 13 seconds cut.

Exploring Curved Schematization of Territorial Outlines.

Hand-drawn schematized maps traditionally make extensive use of curves. However, there are few automated approaches for curved schematization; most previous work focuses on straight lines. We present a new algorithm for area-preserving curved schematization of territorial outlines. Our algorithm converts a simple polygon into a schematic crossing-free representation using circular arcs. We use two basic operations to iteratively replace consecutive arcs until the desired complexity is reached. Our results are not restricted to arcs ending at input vertices. The method can be steered towards different degrees of "curviness": we can encourage or discourage the use of arcs with a large central angle via a single parameter. Our method creates visually pleasing results even for very low output complexities. To evaluate the effectiveness of our design choices, we present a geometric evaluation of the resulting schematizations. Besides the geometric qualities of our algorithm, we also investigate the potential of curved schematization as a concept. We conducted an online user study investigating the effectiveness of curved schematizations compared to straight-line schematizations. While the visual complexity of curved shapes was judged higher than that of straight-line shapes, users generally preferred curved schematizations. We observed that curves significantly improved the ability of users to match schematized shapes of moderate complexity to their unschematized equivalents.

Avaliação do Uso do Tecimento sobre o Nível de Diluição e Geometria do Cordão de Solda na Soldagem TIG com Alimentação Automática de Arame Frio

ResumoEste trabalho tem por objetivo estudar a influência do tecimento na soldagem TIG com alimentação de arame frio em único passe visando à aplicação futura em revestimento de ligas de níquel, considerando a análise das características geométricas e diluição, de forma a adequar estes revestimentos para as indústrias do Setor de Petróleo e Gás Natural. A baixa diluição é necessária para evitar a redução das propriedades de resistência à corrosão dos revestimentos. As soldagens foram realizadas utilizando um robô industrial e um alimentador automático de arame frio. A liga usada como metal de adição foi a AWS ER NiCrMo-3 (Inconel 625) e o substrato foi o aço ASTM A516 Gr. 60. Foram realizadas soldagens com alimentação automática de arame frio na condição sem tecimento e com tecimento tipo triangular, variando a energia em três níveis. Os resultados mostraram que o uso do tecimento influencia consideravelmente a geometria do cordão de solda e o nível de diluição. Com uso do tecimento o reforço do cordão de solda reduziu e a largura aumentou, proporcionando uma melhor distribuição de material sobre a peça, reduzindo com isso a razão reforço/largura (R/L), parâmetro este que indica o grau de convexidade do cordão de solda. Uma razão R/L alta, indica que o grau de convexidade pode ser excessivo, dificultando com isso uma adequada sobreposição de passes para soldagem posterior de revestimentos, com a possibilidade de formação de vazios entre os mesmos. Quanto a penetração e a diluição, ambas apresentaram comportamentos similares, com redução de forma significativa nas condições em que o tecimento é empregado. Estes resultados mostram que o uso do tecimento garante uma combinação de baixa razão R/L com baixa diluição, condição esta desejável para soldagem de revestimentos.

Plasma arc cutting torch tracking control

The present paper is concerned with a tracking system for cutting torch height in the plasma arc process. The computer based control system consists of the sensing and detection unit, controller, and servo actuator. The use of arc and laser sensors to detect the torch height is presented, and their applied characteristics are investigated in detail. A feedforward compensation of workpiece position is introduced to improve tracking properties. Moreover, to address the non-linear characteristics of the arc sensor, deviation classification and adaptive control approaches are also proposed. Tracking experimental results show acceptable tracking precision and strong noise restraining capability for the system. These demonstrate the effectiveness of the sensing and detection, and the proposed control algorithms. It is also shown that the arc sensing approach is more attractive, owing to its merits of synchronous sensing, high reliability, and low cost.

Optimum departure times for commuters in congested networks

We propose an algorithm to compute the optimum departure time and path for a commuter in a congested network. Constant costs for use of arcs, cost functions of travel time depending on exogenous congestion and schedule delay are taken into account. A best path for a given departure time is computed with a previous algorithm for the generalized shortest path problem. The globally optimal departure time and an optimal path are determined by adapting Piyavskii's algorithm to the case of one-sided Lipschitz functions.

Commuters' Paths with Penalties for Early or Late Arrival Time

We formulate the choice of a best path for a commuter leaving his/her home at a given time and willing to arrive at his/her destination within a given time interval. The objective function integrates constant costs for use of arcs, travel times and schedule delay. The travel times along arcs, which depend on exogenous congestion, are represented by functions of the arrival time at the origin node of the arc. The schedule delay is taken into consideration by penalizing arrival time at the destination outside the desired time interval. The problem is shown to be NP-hard, polynomial subcases are determined and a pseudo-polynomial algorithm is provided for the general case.

The Development of My Sculpture and Stained Glass

The author describes the five stages of the development of her work ranging from still-life oil paintings to faceted stained glass and free-standing sculpture in fibreglass-reinforced polyester or in bronze. She traces factors that have affected her work throughout. These are: her interest in philosophy, the use of arcs and ellipses in her works, a quest for ways to achieve a sense of depth and her fascination with transparency and surface reflections. She believes that her theistic view of life is expressed in her constructed designs and balanced compositions, whether she depicts nonfigurative subjects or Christ figures or sculpted forms derived from nature, and, particularly, in the continuity of their lines. Skiing, sailing and gliding appeal to her, because they involve finding and following a ‘right’ line or curve. Her works sometimes recall wakes in water, ski tracks in snow and the shapes of trees. But she regards her interior, mental images as an equally meaningful influence that she wishes to share. She attempts, in her article, to resolve present-day conflicts and paradoxes confronting some visual artists, such as protest or acceptance, art or nature, expert opinion or personal choice, to arrive or to move on, and illustrates her approach to them through her work.

On the existence of rigid arcs

By an arc we mean a nondegenerate simply ordered set which is compact and connected in its order topology. A space X is rigid if the only homeomorphism of X onto itself is the identity map. Examples of rigid totally disconnected compact ordered spaces may be found in [1], [2], and [3]. It is the purpose of this note to prove the existence of an arc such that no two of its subarcs are homeomorphic. The proof makes use of arcs of large cardinality and the technique of inverse limit spaces.

R. L. Moore’s axiom 1′ and metrization

Let S be a Hausdorff space for which there exists a simple sequence G1, G2, -of open coverings such that (1) for each n, GnDG1+,, and (2) if H and K are nonintersecting closed subsets of S one of which is compact, then for some n no element of G. intersects both H and K.2 At the 1957 Summer Meeting of the Society the question arose in connection with M1r. Armentrout's paper, A study of certain plane-like spaces without thve use of arcs,3 as to whether or not S when satisfying certain rather complicated axioms was metric. I remarked that there did exist such nonmetric spaces. This observation was incorrect.

The Use of Arcs and other Fluctuating Sources in Photoelectric Photometry

IN his paper on the registering microphotometer, P. P. Koch (Annalen der Physik, iv. 39, p. 705, 1912) describes an arrangement consisting of two similar photoelectric cells connected to an electrometer, both illuminated by the same source, but through different optical paths. The arrangement described has the advantage of being independent of intensity fluctuations in the source (provided that these are uniform over the area of the source), since the electrometer reading depends only upon the ratio of the intensities falling on the two cells. An example is given in which a change from 10 to 100 in the light intensity of the source produced only a 1 per cent, change in the electrometer deflexion. However, it remained impossible to use arcs, or other light sources which not only fluctuate in intensity but also flicker or change their position; for since the two beams come from different parts of the source, and traverse different optical paths, flickering changes the ratio of their intensities, as well as the absolute values.

Concerning approachability of simple closed and open curves

Schoenfliest was the first to formulate the converse of the fundamental theorem of C. Jordant that a simple closed curve? lying wholly within a plane decomposes the plane into an inside and an outside region. The statement of this converse theorem is as follows: Suppose K is a closed, bounded set of points lying in a plane S and that S K = Sl +-S2, where Si and S2 are point-sets such that (1) every two points of Si (i = 1, 2) can be joined by an arc lying entirely in Si (2) every arc joining a point of Si to a point of S2 contains at least one point of K (3) if 0 is a point of K and P is a point not belonging to K, then P can be joined to 0 by an arc that has no point except 0 in common with K. Every point-set that satisfies these conditions is a simple closed curve. Schoenflies used metrical hypotheses in his proof. Lennes gave a proof of this converse theorem using straight lines. R. L. Moore pointed out that a proof similar in large part to that of Lennes can be carried through with the use of arcs and closed curves on the basis of his system of postulates 23, thus furnishing a non-metrical proof of the converse theorem.? In all these proofs the condition numbered three, the condition of approachability (erreichbarkeit) plays a fundamental role. It is the purpose of the present paper to study the effect of substituting for the condition of approach-

The converse of the theorem concerning the division of a plane by an open curve

In his paper, On the foutndations of plane analysis situs,t R. L. Moore proved that if 1 is an open curvet and S is the set of all points, then S 1 = Si + S2, where Si and S2 are connected point sets such that every arc from a point of Si to a point of S2 contains at least one point of 1.? Clearly the sets Si and S2 are non-compact.11 Professor Moore's theorem is proved on the basis of his set of axioms 13. Thus the theorem is true in certain spaces which are neither metrical, descriptive, nor separable. This theorem for open curves is analogous to the theorem of Jordan,? that a simple closed curve lying wholly within a plane decomposes the plane into an inside and an outside region. The converse of this theorem for simple closed curves was first formulated by Schoenflies,** who makes use of metrical properties in his proof. A different proof has been given by Lennes,tt who uses straight lines. R. L. Moore has pointed out that, on the basis of 13, an argument similar in large part to that of Lennes can be carried through with the use of arcs and closed curves. The object of the present paper is to show that the converse of the open curve theorem holds in spaces satisfying 13. The statement of the converse theorem is as follows:
