Recently, with the continuous evolution of new technology the world has faced unusual growth of multimedia data especially in document images. Huge quantities of documents are created and used in many important official organizations. The stamps assure the authenticity of the documents contents. The general objective of this dataset is enabling researchers in the field of pattern recognition to analyze, detect, localize and recognize different types of stamps. The size of the dataset is 48.9 MB. It contains a total of 1557 color stamps samples which are stored as BMP image format. The images of stamps were acquired from documents using a scanner and mobile camera. The cropping process was applied to capture only the stamp area of the whole document, using three applications which are paint, snip and sketch software. For each cropped stamp, eight stamp images are produced from rotating the original one at different angles clockwise. Rotation starts from 5 degrees and increases by 5 degrees until it reaches to 40 degrees. Note the orientation of the original stamp image is with the horizon line, which means that it is at an angle of zero. The stamps have different size, shape, complexity, position, directions and colors. For example, there are six categories of stamp shapes arranged as circle, oval, square, rectangular, triangular and some other irregular shapes. Its worth to mention that the collected dataset may be degraded in quality and resolution and the stamp can be located on a relatively complex background. The dataset was collected from various sources, including official documents from Iraqi educational institutions, documents from syndicates such as teachers, engineers, doctors, pharmacists, Iraqi hospitals, provincial councils, and most Iraqi institutions. The dataset also contains some stamps from other Arab countries.

Multi- and transgenerational effects of the insecticide Trebon 30 EC (active ingredient etofenprox) on life-history traits of the collembolan Folsomia candida was examined in a four-generation long laboratory study. The experimental set-up of both treatments was similar, except that in the multigenerational treatment all four generations were treated by the insecticide, and in the transgenerational treatment only the parent generation was treated, but the consecutive three generations not. If the generation was treated with insecticide, six sublethal concentrations of the Trebon 30 EC were applied to see dose-response effects. We concluded that the influence of both treatment methods is strong but appreciably distinct. In the multigenerational treatment, when all four generations were exposed to sublethal concentration of the insecticide, the population either become resistant, or it could compensate for the insecticide effect in the long term. According to our results, extinction could only arise if the Trebon 30 EC used repeatedly, and in five times higher concentration than the recommended field concentration. Moreover, a notable and apparent transgenerational effect was found as well. Whereas in the F1 and F2 generations a small number of life-history traits were changed, in F3 generation most of the measured parameters showed significant insecticide effect. This finding clearly indicates the long-term transgenerational effects, which are essential from ecological as well as environmental risk assessment point of view.

Determining how emotional experience influences attention is a long standing goal of cognitive psychologists. Emotion is often broken down into two main dimensions, arousal and valence. While many theories focus more on the influence of one dimension than the other, the systematic investigation of the independent influences of the two dimensions of emotion on attention has been slow in the coming. In order to examine the relevance of both aspects of emotion and their interplay on attention simultaneously, in the current experiment we induced low (satisfaction) and high (happiness) arousal positive emotions and low (sadness) and high (anger) arousal negative emotions in subjects before having them complete an inattentional blindness (IB) test. In line with theories that focus on the role of valence, we found that negative emotions led to more IB than did positive emotions, and that arousal did not influence attention. Data were from an extended version of the EMO 16 akt (Schmidt-Atzert & Hüppe, 1996), the Affect Grid (Russell, Weiss, & Mendelsohn, 1989), as well as an Inattentional Blindness task. The study comprised a one factorial design including the between-subjects factor “induced emotion” with the five levels happiness (positive valence, high arousal), satisfaction (positive valence, low arousal), neutral emotion (neutral valence, low arousal), sadness (negative valence, low arousal), and anger (negative valence, high arousal). The design can also be described as a 2 (valence: positive vs. negative) x 2 (arousal: high vs. low) design with an additional control group (neutral valence with low arousal). The dependent variables were detection rates of the critical stimuli in trial 3 (i.e., the critical trial) and trial 5 (divided attention trial). The extended EMO 16 akt as well as the Affect Grid were collected before emotion induction (_1), after emotion induction (_2), and after the inattentional blindness task (_3). The inattentional blindness task comprised six trials. The 3rd (critical trial, inattentional trial), 5th (divided attention trial), and 6th (full attention trial) included an unexpected stimulus.
