口红颜色的心理效应及其选择情境性

化妆可以改变面部颜色信息,其中口红作用最显著。口红能提高面部对比度,红色本身也有性效应,两者皆可影响社会认知。本研究探索不同口红颜色对社会认知的影响(口红颜色心理效应),找出最能提高情境特质的优选色,并通过口红颜色的选择情境性验证心理效应。实验1在性吸引力、支配性、亲社会3种情境下对涂抹不同颜色口红的女性面孔进行评分。结果发现,红—绿维度(a)高以及亮度(L)高、蓝—黄维度(b)低的口红颜色更能提高冷白皮性吸引力;中高L、高b的口红颜色更能提高暖黄皮性吸引力;冷白皮优选色是粉色和朱红色;暖黄皮没有明显的优选色。L低、a高的口红颜色更能提高支配性;优选色是紫红色、砖红色和朱红色。L高、b低的口红颜色更能提高冷白皮亲社会性;中高L、高b的口红颜色更能提高暖黄皮亲社会性;冷白皮优选色是粉色;暖黄皮优选色是亮橙色和南瓜色。实验2通过指导语操纵3种情境的高低水平,在不同条件下评价情境优选色。结果发现,和低水平情境比,女性在高水平情境中更倾向于选择情境优选色。本研究定义并展现了口红颜色心理效应及其选择策略,具有理论和实践意义。

血中先锋霉素的分离与测定

先锋霉素类药物是广泛使用的抗菌药物,有过敏反应或与青霉素有交叉过敏现象.在工作中我们曾遇到过由于注射先锋霉素过敏致死的医疗纠纷案例.使用文献所报道的高效液相色谱方法和荧光法检案时发现,检血中加入不同沉淀剂离心后直接取样进行液相色谱分析,由于药浓稀释,不易检出而且不能准确定性.荧光法不仅操作繁杂,同样难以定性.我们应用薄层色谱扫描法对几种常见先锋霉素药物的分离、定性做了一些考察,并对最常应用的头孢噻吩钠(先锋霉素1号)在血中的检测作了较为详细的探索,取得了比较满意的结果.

见微知著,掌握色差很重要

设计人员的手头上都要备有一份色谱,设计人员用色谱,主要不是用来分辨色彩黑白的,而是用来区别色彩中的色差,掌握细微的色差对设计很重要.搞收藏裕定的人,对色差的辨别电很重要.例如北宋时期景德镇和景德镇周边窑口,都有用类似工艺烧制影青瓷器的,相同造型的影青釉产品,如何区别窑口,看胎骨是一个方面,主要还是看影青釉之间的色差.色差记载时光,色差也诉说真伪,许多鉴定专家,购买不同时期的瓷片,也是在鉴定时,作胎和色釉之间的对比.

1.1. HLA and other leucocyte and platelet alloantigens in paternity testing (introductory lecture)

The analysis of lipstick stains presented here is a combination of several techniques. In addition to colour comparison and thin-layer chromatographic (TLC) analysis, X-ray analysis in a scanning electron microscope and high-performance liquid-chromatographic (HPLC) analysis have been used. X-ray analysis may be performed directly on the material bearing the stain. For TLC and HPLC analyses a solvent extract of the stain was used.Guidance is given for practical examination of lipstick stains. When using all the methods described in this paper, all the 117 different lipstick samples examined in this study could be distinguished from each other.     

Luminous lip-prints as criminal evidence

Luminescence is specially a useful property for the search of invisible evidences at the scene of a crime. In the latent fingerprints particular case, there are at one's disposal fluorescent reagents for their localization. The study of latent lip prints (that is lip prints from protective lipstick, or permanent or long-lasting lipstick that do not leave any visible marks) is more recent than fingerprints study. Because of the different composition of both types of prints, different reagents have been tried out on their developing. Although, lysochromes are particularly useful reagents to obtain latent lip prints, it may occur on coloured or multicoloured surfaces, the developing is not perceived due to contrast problems between the reagent and the surface where the print is searched. Again, luminescence offers the possibility to solve this problem. Nile Red is being studied as a potential developer for latent lip prints. The results on very old prints (over 1year) indicate that this reagent is highly efficient to get latent lip prints.     

Some Examples of Applications of a Microthermal Desorption Device in the Forensic Laboratory

Abstract:  Several applications of a microthermal desorption device for analysis of small forensic samples are presented. The method uses a solid phase microextraction holder with the fiber removed. In addition to samples of inks on paper, this device was successfully used for analysis of toners, various stains on bank notes, and lipstick stains on paper. Other small items encountered in a forensic science laboratory were also analyzed: particles of smokeless powder, particles of coffee, and automotive clear topcoat layer. The desorbed compounds were analyzed by gas chromatography with a flame ionization detector or by gas chromatography–mass spectrometry. This device can be used in connection with any kind of gas chromatograph. By selection of different injector temperatures, fractionated thermal desorption of samples is achieved. The procedure was demonstrated on samples of ballpoint pen ink of various age.     

Criminalystic: effectiveness of lysochromes on the developing of invisible lipstick-contaminated lipmarks on human skin. A preliminary study

Latent prints are an important evidence for identification. Nowadays, the technical means, the implementation of image processing techniques and the use of database makes it possible to detect and get information from some prints that seem to be useless at first sight. On the other hand, the possibility of using the print as a DNA source has to be considered, so as to double its identifying value. Human skin is a particularly difficult surface for developing this kind of evidences. Although different methods for locating and developing latent fingerprints on the skin have been already described, it has not been found any method, at the revised bibliography, to obtain and develop invisible lipmarks, that is, lipmarks from protective lipstick, or permanent or long-lasting lipstick. The aim of the work that follows is to determine the effectiveness of several reagents for developing invisible lipmarks on the corpses' skin. Preliminary results show that, under the described experimental conditions, the reagents used, Sudan III, Oil Red O and Sudan Black, are effective for obtaining recent latent lip prints on corpse's skin.     

Rapid and nondestructive analysis of lipstick on different substrates using ATR-FTIR spectroscopy and chemometrics

Lipstick can be an important piece of evidence in crimes like murders, rapes, and suicides. Due to its prevalence, it can be an important corroborative evidence in crime reconstruction. The analysis of such evidence can provide an evidentiary link between the suspect, the victim, object, or the crime scene. We report the use of nondestructive ATR-FTIR spectroscopy combined with chemometrics for the classification of 10 brands of lipsticks with nine samples each. Chemometric method of partial least square-discriminant analysis (PLS-DA) has been employed to interpret the data and classify the samples into their respective classes. The PLS-DA model provides an AUC figure above 0.99 in all brands except one; for which it is slightly less at 0.94. We have also tested the traces of these lipstick samples on different substrates treating them as unknowns in the already trained PLS-DA model. 100% of the samples on nine substrates viz. a cotton, nylon, plastic, dry tissue, denim (blue jeans), wet tissue, nitrile gloves, white paper, and polyester were correctly attributed to their source brand. In conclusion, the results suggest that ATR-FTIR combined with the chemometrics is a rapid, nondestructive, and accurate method for the discrimination and source attribution of lipstick. This study has potential for use in actual forensic casework conditions.     

Morphologic patterns of lip prints in a portuguese population: a preliminary analysis

Lip prints are thought to have the ability to distinguish individuals and, hence, have a potential use in human identification purposes. However, questions remain regarding their utility for sex determination. This study aimed to classify lip prints for different individuals in a Portuguese population and to determine whether sex differences exist. Lip prints of 25 females and 25 males were obtained using dark-colored lipstick and cellophane tape. Lip prints were analyzed using a magnifying lens and classified according to the Suzuki and Tsuchihashi classification. A Type II pattern was found to be most common. A comparison of lip-print patterns between males and females showed results with a statistically significant difference: Type III pattern was most common in males, and a Type II pattern in females. This study corroborates the hypothesis that lip prints are able to distinguish individuals and may be useful in sex determination.

Immunochemical studies on blood group A substance from human hair

Blood group A-active substance was extracted from urea-treated human hair uith methanol-ethyl ether 1:1, v/v) or chloroform-methanol (1:1, v/v). The serological activity of blood group A substance in the hair was destroyed by A-decomposing enzyme from Clostridium tertium with concomitant development of blood group H activity. It is concluded therefore that the extract from the hair of group A contained blood group A-active glycolipid with N-acetylgalactosamine as the non-reducing sugar.
