Various materials, depending on the personality of the artist, are required for contemporary art. Thus, it is necessary to decipher the expressive intentions of the artist and characteristics of the materials required for the conservation of such art. The purpose of this study is to analyze the causes underlying the deterioration of sculptures made from soap and to determine the ideal hygrothermal environment required to stably exhibit and store these artworks. Furthermore, we aim to maintain the long-term structures of the artworks in accordance with the changing expressions and intentions of the artist. Our analysis confirmed that the extracts of the soap sculptures were composed of glycerin and that the sculptures were sensitive to humidity. Moreover, we determined that a relative humidity (RH.) of approximately 60~65% made for an appropriate hygrothermal environment required to preserve the sculptures. We also preserved each work in various ways by applying appropriate preservation treatment, and found that the optimum preservation environment for soap sculptures was a temperature of 20±2°C and a RH. of 60±5%.

Abstract Background: Long term venous catheters have been used to deliver specialized therapies since 1968. The ideal tip position of a central venous catheter provides reliable venous access with optimal therapeutic delivery, while minimizing short-and long-term complications. Ideal position limits have evolved and narrowed over time, making successful placement difficult and unreliable when depending exclusively on the landmark technique. Objective: To review and analyze contemporary literature and calculate an overall accuracy rate for first attempt placement of a PICC catheter in the ideal tip position. Methods: Key PICC placement terms were used to search the database PubMED-indexed for MEDLINE in June and October, 2009. The selection of studies required: a patient cohort without tip placement guidance technology; a documented landmark technique to place catheter tips; data documenting initial catheter placement and, that the lower third of the SVC and the cavo-atrial junction (CAJ) were included in the placement criteria. With few exceptions, articles written between 1993 and 2009 met the stated selection criteria. A composite of outcomes associated with tip placement was analyzed, and an overall percent proficiency of accurate catheter tip placement calculated. Results: Nine studies in eight articles met the selection criteria and were included for analysis. Rates of first placement success per study ranged from 39% to 75%, with the majority (7/9) being single center studies. The combined overall proficiency of these studies calculated as a weighted average was 45.87%.

The Ideal

Failure to follow prescribed treatment has devastating consequences for those who are seriously and persistently mentally ill. Nurses, therefore, try to get clients to take psychotropic medication on a long-term basis. The goal is either compliance or adherence. Although current nursing literature has abandoned the term compliance because of its implications of coercion, in psychiatric nursing practice with patients suffering from serious long-term mental illness compliance and adherence are in fact different goals. The ideal goal is adherence, which requires the patient to be an active participant in the team. This goal is consistent with nurses’ ethical values, but for such patients this is frequently unrealistic. If the person is severely psychotic, treatment may be involuntary and the goal compliance. Psychiatric nurses participate in involuntary treatment and thus should acknowledge the ethical implications of compliance as a goal and not obscure the issue by calling compliance adherence.

<p>IAGOS (www.iagos.org) is a European Research Infrastructure using commercial aircraft (Airbus A340, A330, and soon A350) for automatic and routine measurements of atmospheric composition including reactive gases (ozone, carbon monoxide, nitrogen oxides, volatile organic compounds), greenhouse gases (water vapour, carbon dioxide, methane), aerosols and cloud particles along with essential thermodynamic parameters. The main objective of IAGOS is to provide the most complete set of high-quality essential climate variables (ECV) covering several decades for the long-term monitoring of climate and air quality. The observations are stored in the IAGOS data centre along with added-value products to facilitate the scientific interpretation of the data. IAGOS began as two European projects, MOZAIC and CARIBIC, in the early 1990s. These projects demonstrated that commercial aircraft are ideal platforms for routine atmospheric measurements. IAGOS then evolved as a European Research Infrastructure offering a mature and sustainable organization for the benefits of the scientific community and for the operational services in charge of air quality and climate change issues such as the Copernicus Atmosphere Monitoring Services (CAMS) and the Copernicus Climate Change Service (C3S). IAGOS is also a contributing network of the World Meteorological Organization (WMO).</p> <p>IAGOS provides measurements of numerous chemical compounds which are recorded simultaneously in the critical region of the upper troposphere – lower stratosphere (UTLS) and geographical regions such as Africa and the mid-Pacific which are poorly sampled by other means. The data are used by hundreds of groups worldwide performing data analysis for climatology and trend studies, model evaluation, satellite validation and the study of detailed chemical and physical processes around the tropopause. IAGOS data also play an important role in the re-assessment of the climate impact of aviation.</p> <p>Most important in the context of weather-related research, IAGOS and its predecessor programmes provide long-term observations of water vapour and relative humidity with respect to ice in the UTLS as well as throughout the tropospheric column during climb-out and descending phases around airports, now for more than 25 years. The high quality and very good resolution of IAGOS observations of relative humidity over ice are used to better understand the role of water vapour and of ice-supersaturated air masses in the tropopause region and to improve their representation in numerical weather and climate forecasting models. Furthermore, CAMS is using the water vapour vertical profiles in near real time for the continuous validation of the CAMS atmospheric models. </p>

The study aimed to assess the long-term population dynamics of questing Rhipicephalus appendiculatus and Rhipicephalus zambeziensis in two landscape zones of the Kruger National Park (KNP). Ticks were collected by dragging the vegetation monthly in three habitats (grassland, woodland and gully) at two sites in the KNP (Nhlowa Road and Skukuza) from August 1988 to March 2002. Larvae were the most commonly collected stage of both species. More R. appendiculatus were collected at Nhlowa Road than at Skukuza, with larvae being most abundant from May to August, while nymphs were most abundant from August to December. Larvae were most commonly collected in the gullies from 1991 to 1994, but in the grassland and woodland habitats from 1998 onwards. Nymphs were most commonly collected in the grassland and woodland. More R. zambeziensis were collected at Skukuza than at Nhlowa Road, with larvae being most abundant from May to September, while nymphs were most abundant from August to November. Larvae and nymphs were most commonly collected in the woodland and gullies and least commonly in the grassland (p < 0.01). The lowest numbers of R. appendiculatus were collected in the mid-1990s after the 1991/1992 drought. Rhipicephalus zambeziensis numbers declined after 1991 and even further after 1998, dropping to their lowest levels during 2002. The changes in numbers of these two species reflected changes in rainfall and the populations of several of their large herbivore hosts, as well as differences in the relative humidity between the two sites over time.

The paper is oriented on the hygrothermal microclimate of residential interiors in reconstructed building. The questionnaire survey has showed significant increase in number of allergies, respiratory diseases and occurrence of fungi after reconstruction. In order to find causes, experimental measurements of hygrothermal microclimate were carried out. The long term high values of relative humidity were found out and the link with number of efficient natural ventilation was searched for. Ventilation once a day was usual, what was proved as insufficient. Dwellers were informed about right way and number of ventilation. Furthermore, measurements proved decrease of air humidity, but not sufficiently. It was proved that nobody was able to achieve recommended number of ventilation and almost all of them considered it annoying and unreal to sustain. The biggest problem was proved night 7 hour interval. Therefore allergic and respiratory problems were significant in the morning. In conclusions of paper is suggestion for solution of researched problem.

Context. Historical Ca II K spectroheliograms (SHG) are unique in representing long-term variations of the solar chromospheric magnetic field. They usually suffer from numerous problems and lack photometric calibration. Thus accurate processing of these data is required to get meaningful results from their analysis. Aims. In this paper we aim at developing an automatic processing and photometric calibration method that provides precise and consistent results when applied to historical SHG. Methods. The proposed method is based on the assumption that the centre-to-limb variation of the intensity in quiet Sun regions does not vary with time. We tested the accuracy of the proposed method on various sets of synthetic images that mimic problems encountered in historical observations. We also tested our approach on a large sample of images randomly extracted from seven different SHG archives. Results. The tests carried out on the synthetic data show that the maximum relative errors of the method are generally <6.5%, while the average error is <1%, even if rather poor quality observations are considered. In the absence of strong artefacts the method returns images that differ from the ideal ones by <2% in any pixel. The method gives consistent values for both plage and network areas. We also show that our method returns consistent results for images from different SHG archives. Conclusions. Our tests show that the proposed method is more accurate than other methods presented in the literature. Our method can also be applied to process images from photographic archives of solar observations at other wavelengths than Ca II K.

There are two constraints in the process of economic recovery in Indonesia. First, investment rate is decreasing in the last five years. This matter happens due to the bad investment climate in Indonesia. Second, slow growth of export rate in Indonesia. At the present, investment rate in Indonesia is only 22 percent of GDP, while the ideal rate is 30 percent of GDP. Another problem, which may be interrupting the economic recovery, is de-industrialization. The sign of de-industrialization occur by relocation phenomena of FDIfrom Indonesia. This research analyze the effects of direct investment and export to GDP. The tool of analyses of this research is econometric model known as Error Correc­tion Models. The results shows that in a long term and short term, export and direct investment do not have a significant effect to GDP. It shows that Indonesia do not have a clear policy about export and investment. The policy implications of this research are government should have a deregulation policy in the industry and recover investment climate.
