Abstract Travelling with harmonical actions about the referential line, the moment the photon qubit emits form the atom as a packet, not only embedded by the envelopes of quadratic nature overlap but also by the non-quadratic overlap effect as well in concurrent. This paper followed on by the subsistence of both ways of overlapping, focuses mainly on the induced metric of photon qubit, which concluded to be in 3-sphere by the local parameterization so called as Hopf coordinates. The protruded photon qubit in the induced Riemannian metric, for different points of the Bloch sphere, are in a manner that the stereographic projection of volume enveloped in 3-sphere determines the circular geometry in 2-sphere with the cross-sectional function in perpendicular to the continuum line of travel.

This paper deals with the loss of FL-vocabulary in French and German learned in formal secondary Dutch education ("VWO). Using a cross-sectional design, we investigated the development of FL-vocabulary from the end of grade 4 - the moment at which pupils can drop one or two FLs - up to the end of grade 6 - the moment when they take their final exams in the seven subjects they did choose. We compared pupils from grades 4, 5, and 6 who had either dropped the FL, or had chosen it as an exam subject. A French and a German translation task were administered in which pupils had to fill in the target word in a meaningful, but noncoercive context. The tests consisted of a productive part (translation into the FL) and a receptive part (translation from the FL). Either part consisted of 48 equivalent items, 24 high-frequent and 24 low-frequent target words. The main finding was that there was a loss of 16% for French in the second year of non-use, and a comparable loss for German in the first year of non-use. However, the loss for German was entirely redressed in the second year of non-use. It was concluded that this may have been due to the cross-sectional design, and that, therefore, longitudinal designs are to be preferred in this kind of research.

For an extensible cable with a free end, the exact nonlinear differential equations that describe the final shape of the cable present difficulties when one tries to integrate them to find the angle of inclination in the vicinity of that free end. To circumvent these difficulties, a method is proposed wherein the cable is replaced by a flexible rod. The moment of inertia of the cross-section of the rod is then allowed to approach zero while the cross-sectional area and the length of the rod remain finite. In that process, the rod approaches the cable as a limiting case, but since the rod has a proper differential equation on the inclination, no singularity occurs. To establish the validity of the method, two cases without a free end are considered first. For these, cable solutions previously obtained by the author are used for comparison. After that, the method is used to solve two cases involving a cable with a free end. In each of these two cases, the cable is suspended in a moving fluid, but they differ in the assumptions made about the drag force. The results obtained appear reasonable and suggest that this method, tantamount to removing the idealization of perfect flexibility from the cable, shows promise as a method of analyzing cables with a free end.

The only form of cellulose which could unequivocally be ascribed to the animal kingdom is the tunicin that occurs in the tests of the tunicates. Recently, high-resolution solid-state l3C NMR revealed that tunicin belongs to the Iβ form of cellulose as opposed to the Iα form found in Valonia and bacterial celluloses. The high perfection of the tunicin crystallites led us to study its crosssectional shape and to compare it with the shape of those in Valonia ventricosa (V.v.), the goal being to relate the cross-section of cellulose crystallites with the two allomorphs Iα and Iβ.In the present work the source of tunicin was the test of the ascidian Halocvnthia papillosa (H.p.). Diffraction contrast imaging in the bright field mode was applied on ultrathin sections of the V.v. cell wall and H.p. test with cellulose crystallites perpendicular to the plane of the sections. The electron microscope, a Philips 400T, was operated at 120 kV in a low intensity beam condition.

The Moment

Breast feeding is giving milk to be drunk to the baby from the breast. Uterus involution is a process how the uterus return to the condition back, before pregnanting after bearing. At the moment of suckling, happens a stimulus and brings the hormones out, such as oksitosin uses not only to stimulate some muscles constraction but also to stimulate the uterus, so that the process of uterus involution happens foster. According to the explanations above, the research aimed to know about the correlation between breast feeding and uterus involution. This research’s design was, cross sectional by the population of all childbirth mothers approximately 50 persons / month. By using accidental sampling technique we got 21 sample respondents. The place of research in RSIA Aura Syifa in Kediri Regency on 16th until 22nd of June 2009. From this research’s result, we got 14 persons (66,67%) with normal uterus involution, suckled in a good way, one person (4,67%) with normal uterus involution, suckled in a wrong way, 2 persons (9,52%) with abnormal uterus involution, suckled in a good way and 4 persons (19,05%) with abnormal uterus involution, suckled in a wrong way. Statistic test which used chi-square test, counted the probability frequency in advance, from that we got 3 columns with the score, less than 5, so that chi-square can not be continued and by doing exact fisher test, the score was 0,001. Because P with the grade mistake 0,05 smaller, so the conclusion was “Ho” is rejected, it meant “there was correlation between suckling and uterus involution”. Key Word : Breast feeding, uterus involution

Abstract The cross-sectional and planar analysis of current generation 3D device structures can be analyzed using a single Focused Ion Beam (FIB) mill. This is achieved using a diagonal milling technique that exposes a multilayer planar surface as well as the cross-section. this provides image data allowing for an efficient method to monitor the fabrication process and find device design errors. This process saves tremendous sample-to-data time, decreasing it from days to hours while still providing precise defect and structure data.
