Aggression in painting - painting as a means of release of aggression.

Painting is a primordial expression. It is not as rigidly defined, edited and criticized as verbal expression. On the other hand, society is more tolerant of painting, and subjects otherwise taboo, like sex, are not rejected. Through painting, aggression can be expressed in different ways, by using piercing and sharp forms; colors that clash; color can be put on the canvas with anger, used as a material. Aggression can also be expressed in the content of the painting, like in a story with an aggression plot. When we encourage individuals to channel their aggression in socially tolerated ways, we teach the aggressive person to release his aggression without jeopardizing his place in society and help him to accept socially approved values and attitudes. We can define this achievement as a step towards the social rehabilitation of the aggressive individuals. The paintings, 16 in all, of 8 mental patients are analyzed.

[Microbial settlement of paint- and building-materials in the sphere of drinking-water. 1. Information: long time observation of a bitumen paint in a drinking-water-reservoir (author's transl)].

In a drinking water reservoir with a freshly applied bituminous coating a microbial settlement was found on the walls. Its development was observed over a period of 23 months. The slime on the walls consisted of bacteria and fungi and was secondarily colonized by protozoa and nematodes. The quantities of the microbial coating decreased during a 12 months time. In the beginning of the time of observation a high number of bacteria was found in the water. The carbon fixed by the microbes came from fossile sources to an amount of 90%.

[Microbial settlement of paint- and building-materials in the sphere of drinking-water. 2. Information: experimental examination of bitumen paint under working conditions (author's transl)].

A bituminous coating material for drinking water reservoirs was applied on testing plates for a microbial examination. In function of the chlorine content of the water a microbial slime layer could be found on the testing plates. The amount of slime became less in course of the time or was not produced at all, when the plates were desiccated before the experiment for some months. A slime layer could never be observed on plates of asbestos cement and polyacryl as inert materials for comparison. Different microbial populations were observed.

Chromosome painting in plants: history and future perspectives.

Chromosome painting was developed in mammalian species nearly four decades ago and rapidly became a powerful tool for chromosome identification, comparative cytogenetics, and evolutionary genome analysis. Comparative chromosome painting among diverse mammals generated much of the foundational knowledge of chromosome structure, chromosomal rearrangements, and karyotype evolution before the advent of whole-genome sequencing. Although chromosome painting was first demonstrated in plants in 2001, its applications remained largely restricted to a few plant lineages until the development of oligonucleotide (oligo)-based chromosome painting in 2015. During the last decade, oligo-based chromosome painting has transformed plant cytogenetics, enabling many investigations that were previously impossible. These studies have provided new insights into meiotic chromosome pairing, crossover formation, chromosome fusion, karyotype stability, and chromosome evolution across diverse plant lineages. This review summarizes the history of technological development of chromosome painting in plants, highlights major discoveries enabled by oligo-based chromosome painting, and discusses future opportunities, particularly the integration of chromosome painting with three-dimensional chromosome and genome biology.

Airless paint gun injuries: an update.

The airless paint gun delivers paint at pressures approximating 3,000 psi. Paint accidently injected into the skin under this pressure causes a devastating injury which is a result of the paint material, the level of bacterial contamination, and the pressure at which the paint is delivered. The time interval between injury and treatment seems a critical determinant of outcome. Decompression of the closed vascular compartments of the hand must be begun immediately to release the underlying tissue distended by the injected paint. Judicious wound debridement must be performed. Immediate antibiotic treatment is indicated in all patients. Studies seem to indicate that steroids limit the severity of inflammatory response. A regimen of hydrocortisone sodium succinate, 100 mg IV, administered immediately before surgery should be followed by a seven-day tapering course of oral prednisone starting with 40 mg on the first postoperative day. Recent safety measures and consumer warnings through the Consumer Product Safety Commission may reduce the number of airless paint gun injuries.

The effects of hyalurodinase upon tumor formation in BALB/c mice painted with 7,12-dimethylbenz-(a)anthracene.

Experiments were performed to investigate the effects of hyaluronidase on chemical carcinogenesis. Two experiments were carried out using BALB/c mice. In the first experiment the mice were divided into three groups, viz. (1) painted with 7,12-dimethylbenz(a)anthracene (DMBA), (2) injected with hyaluronidase and painted with DMBA and (3) injected with saline and painted with DMBA. In the second experiment the mice were divided into three groups: (1) painted with DMBA, (2) injected with hyaluronidase and painted with DMBA and (3) injected with heat-inactivated hyaluronidase and painted with DMBA. The tumor incidence and size of tumors were significantly lower in the group treated with hyaluronidase than in the other groups. The latent period was increased. The mitotic index of the skin adjacent to the tumors at the end of the experiment was decreased. These studies show that hyaluronidase can act as an anticarcinogenic agent.

The distribution of 2,4-dinitrophenyl groups in lymphoid tissue of guinea-pigs following skin painting with 2,4-dinitrochlorobenzene.

Cellular localization of 2,4-dinitrophenyl (DNP) groups in the peripheral lymphoid system of guinea-pigs was studied at various times after painting the skin with 2,4-dinitrochlorobenzene (DNCB) by the immunofluorescent method using anti-DNP antibody. The cells taking up the stain (DNP cells) were shown to be mainly lymphocytes. At 1-6 h after painting the majority of DNP cells were found in the peripheral blood and the spleen but the maximum number was reached in the lymph node draining the site of DNCB application 12 h after painting. Injecting cyclophosphamide (CY) 3 days before painting with DNCB, heightened the number of DNP cells residing in the draining node. The animals treated with the tolerogen, 2,4-dinitrobenzene sulphonic acid sodium salt (DNBSO3Na), and then painted with DNCB, had fewer DNP cells than those animals which had simply been painted once with DNCB. The culture supernatants prepared from the draining nodes of both normal and tolerant animals partially blocked the anti-DNP antibody binding with DNP cells. It is suggested that the cells associated with DNP groups residing in the draining lymph node act as immunogens in the immunizing process of contact sensitivity.

A Kansei-mediated protocol for transforming painting palettes into product aesthetics.

To address users' increasingly diverse aesthetic and emotional needs, this study develops an innovative product color design framework based on Kansei. The proposed method transfers color from paintings (source) to consumer products (target) using Kansei as an intermediary, thereby enhancing the affective quality of color and the perceived design value. The framework initiates with cluster analysis to extract color feature groups (CFGs) from paintings. Subsequently, product color genomes (PCGs) are constructed through functional and structural analysis. Following this, subjective evaluation quantifies Kansei for both CFGs and PCGs, identifying representative groups linked to specific Kansei words. Finally, a Kansei-mediated mapping bridges painting CFGs and PCGs to execute the transfer. Validated using Chinese paintings and a coffee machine, the method effectively transfers painting color schemes, enriches product design, improves color quality, and supports culturally adaptive design within international marketing strategies.

Pyrolysis-gas chromatographic analysis of black paints.

Samples of 79 black paints from 27 manufacturers in the United States were examined to determine the extent to which paints can be distinguished by pyrolysis-gas chromatography. Evaluation by a Carbowax column showed some differences among paints from different manufacturers and among batches of paints from the same manufacturer. However, it was not possible to conclude that paints with identical chromatograms had a common origin.

Programmed energy dispersive X-ray analysis of top coats of automotive paint.

Elemental, qualitative, and semiquantitative analyses of 1974 U.S. automotive paints by a Finnigan Model 900F Energy Dispersive X-ray (EDX) Spectrometer are examined. This EDX analytical system incorporates a minicomputer to receive, store, and present data. The paint samples were received from the National Bureau of Standards (NBS) Law Enforcement Standards Laboratory as a collection representative of the top coats used on all U.S. manufactured automobiles in 1974. Aspects considered include EDX system stability, homogeneity of similarly catalogued samples from different NBS collections, categorization of paints by predominant constituents, and comparison of data on paint standards that were similar. Automated analysis represents an important application of forensic science to the characterization of paint samples and provides for the nondestructive analysis of a variety of materials in a large range of sample sizes and concentrations.

[Exposure to organic solvent vapors during production of lacquers for automobile painting].

This study was aimed at the development and improvement of the methods for determining solvent vapours to estimate occupational exposure in paint and varnish shops. Gas chromatographic method and mass spectrometry (GC-MS) were applied respectively for quantitative determination and identification of toxic substances in the work-room air in plants manufacturing carbamide car paints and commonly used phthalic paints. Particular attention was paid to aromatic hydrocarbon components of farbasol: ethyltoluenes, propylbenzene, isopropylbenzene, mesitylene, hemimelitene, pseudocumene, diethylbenzenes and cymene. These hydrocarbons constitute about 95% of farbasol. At present, the evaluation of exposure in paint and varnish factories and in paint shops in Poland is insufficient because of the lack of TLV values for the above solvents, as well as inadequate methods of determination used in majority of laboratories.

Suppression of antibody responses by cells from mice painted with picryl chloride.

T cells from mice painted with picryl chloride inhibit secondary IgG anti-TNP antibody responses of normal mice to the sensitizer. Like other suppressor T cells produced after painting which inhibit DNA synthesis and the generation of cytotoxic T cells, these cells could be produced in adult thymectomized mice but not by mice treated with high doses of cyclophosphamide (250 mg/kg). The cells had to be injected within 48 h of a primary painting to inhibit the response to challenge 2-3 weeks later. This associated with their ability to inhibit DNA synthesis in draining lymph nodes after a primary painting. Double transfer experiments using spleen and lymph node cells failed to show any further activation or induction of suppressor function after challenge with antigen. As judged by the ability of anti-theta treated cells from suppressed mice to function as anti TNP primed B cells in adoptive responses to TNP-KLH no defect in B-cell memory was found. When, however, the ability of painting with picryl chloride to prime for challenge with TNP-KLH was used as a measure of B-cell function in situ it was found that the cells could inhibit responses. Responses to primary and secondary injections of TNP-KLH were not inhibited.

Hazardous substances. Determination of pentachlorophenol in toy paints.

A simple procedure is described for the routine determination of pentachlorophenol (PCP) in various types of toy paints. PCP can be determined in water colors, body colors, showcard paints, gouache paints, and colored inks. PCP is extracted from the sample with acetone, followed by quantitative gas chromatographic analysis of the concentrated acetone extract on stainless steel columns containing 15% Carbo-wax 20M on 60-80 mesh Chromosorb P (AW). As little as 1 ppm PCP can be determined with recoveries ranging from 50 to 100%, depending on the type of paint. The presence of PCP in samples is confirmed by thin layer chromatography, using dansyl chloride as a fluorescent labeling compound. By this method as little as 4 ppm can be determined. The results of PCP determinations in 65 commerical samples are presented.

Effect of ULV malathion on automotive paint finishes.

The relationship between malathion droplet size (VMD) and degree of damage to 1990, 1K and 2K General Motors paint standards was investigated in the laboratory and field. Laboratory tests indicated a positive correlation between malathion droplet VMD and damage spot size. Laboratory settling chamber tests revealed that size-thresholds of droplets too small to cause visible damage averaged 8 and 11 mu on washed 1K and 2K paints, respectively. Field tests indicated malathion caused no visible damage to 1K or 2K paint panels under routine operating conditions, although droplet sizes (VMD) sampled on the automobile surface averaged 10.2 +/- 4.5 and 11.7 +/- 5.7 mu. Microscopic damage was found on paint panels placed on the hood, roof, trunk and doors of the automobile when parked parallel or perpendicular to the course of the spray truck and when driven through the spray of a stationary spray truck.

Portable X-ray fluorescence instruments for the analysis of lead in paints.

In a study in the laboratories of the Chicago Board of Health, the results from determination of lead in paint films by X-ray fluorescence were compared with results from determination by atomic absorption. Portable instruments of three suppliers were used for X-ray fluorescence measurements. An improved version of one of these instruments was also tested. The results of X-ray fluorescence readings on painted card stock panels with one of these instruments compared satisfactorily with the results as determined by the atomic absorption method at levels below 10 mg of lead per square centimeter. Readings on multiple layers of these panels were additive and independent of the order of these panels. All four instruments were tested in the laboratory on painted surfaces from the walls of condemned buildings. The most recent version of each instrument gave a correlation coefficient of 0.96 or better for the linear regression of lead values in milligrams per square centimeter by atomic absorption against instrument readings. It was calculated that a reading of 3.2 or greater on any of the instruments would indicate with greater than 95 percent confidence that 1 mg or more of lead per square centimeter would be found when a sample of the paint was analyzed by atomic absorption. When the readings of one of the instruments showed lead to be absent, that result would inidcate with better than 95 percent confidence that less than 1 mg of lead per square centimeter would be found by the atomic absorption method. Portable X-ray fluorescence instruments can be used in situ to determine whether the walls of a building give readings for lead above the range of 0 to 3.2. Walls with readings above this range can be considered to have 1 mg or more of lead per square centimeter and would not be in conformance with the code of the City of Chicago. Samples would need to be taken for analysis in the laboratory by atomic absorption only from those walls with readings within the range of 0 to 3.2.

Tumors and amyloidosis in mice painted with crude oil found on bathing beaches.

Oil lumps collected on the beaches of Israel in 1970, 1971 and 1973 were extracted with pure acetone and the extracts were used to paint the skin of mice twice weekly for 12 months. The oil lumps originated from crude oil spilled from tankers. The less recently collected oils induced papillomata and lymphomata in some animals. They were also more active than the recent oil in the induction of generalized amyloidosis. Mice painted for 12 months with acetone alone developed amyloidosis to a similar extent as those painted with the oldest oil. In previously reported experiments, however, acetone was much less active than the oil in producing amyloidosis after 5 months of painting. The possibility that acetone and oil might act both synergistically or to be antagonistic at different phases of amyloidogenesis is discussed.

Arthritis in Flemish paintings (1400-1700).

A close examination of the hands of people depicted in paintings of the Flemish school showed that in five paintings there were figures with hand lesions resembling those of rhematoid arthritis. Although none of the deformities or swellings are indisputable examples of rheumatoid arthritis, they do at least suggest that the painters must have been confronted with rheumatoid-like lesions in their models. In two other paintings there were signs of rheumatic fever and of temporal arteritis. No arthritic lesions were found in the works of painters of the Italian Renaissance, probably because they are less detailed. The finding of rheumatoid deformities in the Flemish paintings does, however, question the general belief that rheumatoid arthritis is a condition that has arisen relatively recently.
