Finding the Silent Message: Nurses’ Experiences of Non-Verbal Communication Preceding a Suicide  [PDF]
Patrik Rytterstr?m, Mirja Lindeborg, Sari Korhonen, Tabita Sellin
Psychology (PSYCH) , 2019, DOI: 10.4236/psych.2019.101001
Abstract: Suicidal individuals often communicate their intention to commit suicide, but not necessarily verbally. Psychiatric nurses play a central role in the care of patients exhibiting suicidal behaviour or thoughts. Thus, the aim of this study was to explore nurses’ experiences of the indirect messages about forthcoming suicide from patients’ everyday life before they committed suicide. A qualitative design was used with a phenomenological hermeneutical approach. Seven nurses working in specialist psychiatric care were interviewed about their experience of the phenomenon communication about suicide. Results show how the nurses noticed changes in patients just before they committed suicide. These changes included rapid improvement, disguise of real feelings, and unreceptiveness to further treatment or encouragements. The nurses also described patients becoming aware of painful life conditions of losing hope and confidence in the future and experiencing feelings of powerlessness or an inability to influence the situation. Their last moments were characterised by a greater preoccupation with thoughts about death and finding ways to express farewells. This manifested itself in practical preparations and expressing gratitude to people, which was understood by the nurses as a way of saying goodbye. This study shows that it is possible for skilled staff to develop an understanding of a suicidal patient’s internal state and to recognise the non-verbal messages of someone who later committed suicide. The knowledge of how patients prepare and act before suicide could be used to complement a structural suicide risk assessment.
The dependence of water potential in shoots of Picea abies on air and soil water status
A. Sellin
Annales Geophysicae (ANGEO) , 2003,
Abstract: Where there is sufficient water storage in the soil the water potential (Ψx) in shoots of Norway spruce [Picea abies (L.) Karst.] is strongly governed by the vapour pressure deficit of the atmosphere, while the mean minimum values of Ψx usually do not drop below –1.5 MPa under meteorological conditions in Estonia. If the base water potential (Ψb) is above –0.62 MPa, the principal factor causing water deficiency in shoots of P. abies may be either limited soil water reserves or atmospheric evaporative demand depending on the current level of the vapour pressure deficit. As the soil dries the stomatal control becomes more efficient in preventing water losses from the foliage, and the leaf water status, in turn, less sensitive to atmospheric demand. Under drought conditions, if Ψb falls below –0.62 MPa, the trees' water stress is mainly caused by low soil water availability. Further declines in the shoot water potential (below –1.5 MPa) can be attributed primarily to further decreases in the soil water, i.e. to the static water stress. Key words. Hydrology (evapotranspiration · plant ecology · soil moisture).
A Qualitative Study of Males’ Perceptions about Causes of Eating Disorder  [PDF]
Karin Wallin, Gunn Pettersen, Tabita Bj?rk, Maria R?stam
Psychology (PSYCH) , 2014, DOI: 10.4236/psych.2014.515187
Abstract: Our knowledge about males’ perceptions about causes of eating disorder is very limited, but can be useful in the treatment planning for males. The aim of this study was to describe how male former patients perceived causes of onset of their eating disorder. Fifteen males previously treated for eating disorders and now considering themselves as recovered where interviewed at ages 19 - 52. All interviews were recorded and analyzed qualitatively using a phenomenographic approach. Three categories of perceived causes of onset of eating disorders were found. The first category: self-dissatisfaction, was presented with three conceptions: “High achievements and demands”, “Body-dissatisfaction” and “Low self-esteem”. The second category: family environment, comprised the two conceptions: “Difficulty in family interaction and communication” and “Excessive expectations from family members”. The third category was stressful events outside the family, and consisted of the three conceptions: “Bullying, bad situation at school”, “Moving to new places/separation from friends” and “Societal ideals”. Males’ perceptions of causes of onset of their eating disorder were in many aspects similar to those earlier described for women. In treatment, it is important that the clinicians show a sincere interest in perceived causes, since it may facilitate a good working alliance with the patient.

Engevista , 2012,
Abstract: : In this work, the managment of class II solid waste, classified according ABNT NBR10.004, was performed from diagnosis applied in the processes of Resin Transfer Molding (RTM) and Sheet Moulding Compound (SMC) used in the manufacture of composite parts formed from unsaturated polyester resin reinforced with glass fibre, applying cleaner production activities, giving priority to source reduction, reuse and recovery. The diagnosis in the survey consisted of waste quantification and identification of the generating area before and after application of waste management. With the actions taken, there was a reduction of 67.3 kg of class II solid waste per ton of products produced, representing a reduction of 24.81%. In absolute terms during the period analyzed, a minimization of 22,079.64 kg was obtained, representing a savings of more than R$ 2,800.00 per month with only the final disposal of waste to landfills. With the measures taken and the proposals to minimize, over a year, that revenue would be more than R$ 55,000.00.
Durable Effect of Radioactive Iodine in a Patient with Metastatic Follicular Thyroid Carcinoma
Aubrey A. Carhill,Rena Vassilopoulou-Sellin
Case Reports in Endocrinology , 2012, DOI: 10.1155/2012/231912
Abstract: Objective. Thyroid cancer is the most common endocrine malignancy and fastest increasing of all cancers in both men and women in the United States. Traditionally, differentiated thyroid cancer (DTC) carries a good prognosis when diagnosed early, but increasingly patients are presenting with late-stage disease and bone metastasis which carries a poor prognosis. Treatment of DTC involves surgical resection followed by radioactive iodine (RAI), which conventionally is thought to reach maximal effectiveness between 6 and 12 months following treatment. We report a case and review the literature surrounding long-term effect of radioactive iodine treatment in metastatic thyroid carcinoma. Methods. Patient clinical encounter and the literature review. Results. We describe a 49-year-old woman with symptomatic metastatic follicular thyroid cancer (FTC) to the spine and radiographic evidence of spinal cord compression who was effectively treated with RAI. Her initial serum thyroglobulin (Tg) levels following total thyroidectomy were 1,343 ng/mL which dramatically dropped to less than 100 ng/mL following RAI. Forty-three months following treatment with RAI, she has experienced complete resolution of her symptoms and continues to maintain persistently low-thyroglobulin levels of less than 100 ng/mL. Conclusions. RAI is believed to reach peak efficacy within 6–12 months; however, little has been reported regarding the long-term duration of benefit. This case demonstrates that the benefits of RAI therapy may be enduring, even in patients with widely metastatic thyroid cancer. It suggests in clinically stable patients with declining thyroglobulin after treatment, that there may not be an immediate need for additional therapy as RAI treatment may provide lasting effects.

Abstract: in step-conditioning (etching) of acrylonitrile-butadiene-styrene (abs) terpolymer, use is generally made of sulfuric/chromic acid solutions resulting in the generation of highly toxic, environmentally polluting waste. the present work reports the results of a study of reduction and replacement of chromic acid from the etching solution. the samples conditioning was carried out in baths containing solutions of chromic and sulfuric acids, potassium permanganate and phosphoric acid, and sulfuric acid, phosphoric acid and potassium dichromate, varying concentration, etching time and temperature. the morphology and structure of the samples surface were analyzed by scanning electron microscopy (sem), roughness and infrared spectroscopy (fitr/atr) and the adhesion quality of the metallized samples was evaluated by visual inspection, adhesion test and corrosion by a salt spray. the results show that chemical conditioning causes removal of abs components of the samples surface, causing changes such as increased roughness and formation of pores and microcavities, which influenced the metallic adhesion and were dependent on the solution and the conditions employed. chromic acid can be used in concentration smaller than 400 g.l-1 and less aggressive solutions were effective in changing the surface and promoting metallic adhesion.

Introduction An estimated 56,000 new cases of thyroid cancer will be diagnosed in the United States in 2012 [1]. Although the incidence of tumors <1.0?cm has risen with improved detection techniques, the incidence of tumors of any size, especially tumors >4?cm with distant metastases, has also risen [2]. Increasingly, patients are presenting with late-stage disease, particularly aggressive-differentiated thyroid cancer (DTC) with bone metastases [3, 4]. DTC is the most common form of thyroid cancer and includes papillary thyroid cancer (PTC; >85%) and follicular thyroid cancer (FTC; 5–10%). Most patients with DTC undergo surgical resection followed by treatment with radioactive iodine (RAI) and thyroid hormone suppression [5]. Although RAI is believed to reach maximum effect at 6–12 months,

First order phase transition and tricritical point in multiband U(1) London superconductors
Karl A. H. Sellin,Egor Babaev
Physics , 2015,
Abstract: The order of the superconducting phase transition is a classical problem. Single-component type-2 superconductors exhibit a continuous "inverted-XY" phase transition, as was first demonstrated for U(1) lattice London superconductors by a celebrated duality mapping with subsequent backing by numerical simulations. Here we study this problem in multiband U(1) London superconductors and find evidence that by contrast the model has a tricritical point. The superconducting phase transition becomes first-order when the Josephson length is sufficiently large compared to the magnetic field penetration length. We present evidence that the fluctuation-induced dipolar interaction between vortex loops makes the phase transition discontinuous. We discuss that this mechanism is also relevant for the phase transitions in multicomponent gauge theories with higher broken symmetry.
