In this letter to the British Medical Journal, Winnicott discusses how good citizenship comes from the life of the child in his own home, including the first relationship between infant and mother. On the basis of this relationship, more complex relationships are developed at home and in the wider world. If these things fail, citizenship (or something else) has to be taught. Among other issues, he insists that professionals should refrain from interference with infants and small children, that avoidable physical treatment should not be undertaken, nor should infants and small children be taken from home except in case of dire necessity. He reminds the reader that no-one can tell a mother how to be a mother or a teacher how to teach; parents and teachers have to carry on intuitively.

In the recent past, two dimensional gel electrophoresis has emerged as a powerful molecular biology tool for the comparative expression profiling of complex protein sample. It involves the separation as well as the resolution of diverse proteins sample on the basis of isoelectric points and molecular mass of protein in two dimension ways. In this way, it reflects the view of overall proteome status including differentiation in protein expression levels, post-translational modifications etc. Moreover, this allows the identification of novel biological signatures, which may give a particular identity of pathological background to cells or tissues associated with various types of cancers and neurological disorders. Therefore, by utilizing such tools, one can clearly investigate and compare the effects of particular drugs on cells of tissues and also one can analyze the effects of disease on the basis of variations in protein expression profile at broad spectrum. Recently, to get more error-less and accurate proteome profile, conventional 2-D gel electrophoresis has been enhanced with the inclusion of different types of protein labeling dyes which enables a more comparative analysis of diverse protein sample in a single 2-D gel. In this advanced technique (2-D-DIGE), protein samples are labeled with three different types of CyDyes (Cy2, Cy3, and Cy5) separately and combined and further resolved on the same gel. This will facilitate the more accurate spot matching on a single gel platform and will also minimize the experimental variations as commonly reported in the conventional 2D-gel electrophoresis. Therefore, in the present proteomic research era, 2D-DIGE has proved to be an extremely powerful tool with great sensitivity for up to 125 ng of proteins in clinical research volubility especially, neurological and cancer related disorders.

Due to the long lifespan of the cemetery, the pottery discovered in Żelazna Nowa is relatively diversified. Unfortunately, the majority of the graves have been partly damaged, and some have been completely destroyed. In many cases only grave bottoms were recorded, while the furnishings were scattered over a large area. Sometimes (e.g. in feature 56) one cannot be certain whether fragments of vessels uncovered in a grave pit indeed belonged to the burial urn. A few graves from the Younger Pre-Roman period were relatively well furnished in vessels, but the state of preservation rarely makes it possible to determine the actual number of vessels in particular graves. The same holds true with respect to Early Roman period pottery. Graves dated to this period often survived only in their bottom parts. Hand-made vessels prevail by far in the ceramic material. The only few wheel-made sherds were found in the cultural layer in the vicinity of the groove feature. Vessels used as burial urns were those representing Liana types II.2, II.3, and group III. The predominant vessel forms among Younger Pre-Roman period pottery were cups of Dąbrowska types I.2, 3, 4, 5, and 7, bowls II.13, and bulbous vessels. Roman period pottery is primarily represented by vessels of types II.2 and 3; group III; and small bowls of group VI.1 and 2. Some unique forms were identified as well, including a jug with a canal in feature 56 and a small bowl imitating glass vessels. A total of 490 small finds (including those from the modern period) were discovered in the cemetery. Due to severe damage to the cemetery, only some of them have been recovered from features (204), while 181 small finds have been found outside the context of features. Surface surveys were performed several times in the site, and these produced another 105 small finds, most of them found in the western and northern parts of the cemetery. With 54 items discovered, brooches prevail among the small finds. They include four Late La Tène brooches of type N, fragments of A.II or mixed A.II/IV brooches; A.III brooches; a significant number of A.IV brooches, including a few specimens of A.67 and A.68, trumpet brooches, and derivatives of strongly profiled brooches; brooches of series A.V, including A.96, A.120, and A.137; fragments of A.VI brooches; A.VII brooches; a fragment of a Gallic brooch of Rih’s variant 2.2.4; a brooch of Riha’s variant 5.17.5; and a Norico-Pannonian brooch of type A.236. Belt pieces included a clasp of type Kostrzewski 49, seven buckles (most of them of type D.1), two profiled group I variant 6 belt finials, and a set of belt fittings found inside the urn in grave 37, consisting of a buckle, a finial, and a ring. Ornaments are represented by fragments of a knotenring from feature 33, fragments of Kamieńczyk type bracelets and a bar bracelet, several appliques, among them a fragment of a silver plaque, and many fragments of melon beads and glass beads. Weapons are rare in the cemetery: surviving are primarily fragments of shield grips, rivets from shield bosses (fts. 6 and 7), complete spearheads (fts. 41, 48, stray find), and fragments of spearhead sockets (ft. 41, stray find). The finds included two sets of two spearheads each, found in graves, and uncontexted finds of a sword scabbard chape and a spur. Tools and objects of everyday use are relatively well-represented: 19 knives, 8 awls, 1 awl-like tool, 2 needles, 16 clay spindle-whorls, 2 whetstones, a polishing plate, iron fittings of the box, chest locks, fragments of key (?), a massive rim fitting, 2 fragments of combs, 2 fragments of dice, a fragment of an E.139–144 glass vessel, and an immense number of unidentified artefacts made of bronze and iron.

Tube hydroforming (THF) is an innovative method with a potential to form parts of various geometric complexities from tubular materials using pressurized fluid as a soft die. The process has numerous advantages over stamping: a) high strength to weight ratio, b) part consolidation, c) accuracy, d) improved stiffness, e) reduced scrap rate, and f) design flexibility. Optimal utilization of this method, particularly for hydoforming of complex parts, could be realized if better lubrication systems are devised. In an attempt to develop robust lubrication system for THF, the influence of textured d

Most stroke victims undergo muscular disorders leading to weakening of muscles and inability to perform normal hand activities. An exoskeleton device is therefore needed to aid in performing basic hand movements to improve the quality of life of the victims. Most of the available devices in literature are controlled using electrical motors with a rigid structure and complex design. This paper discusses the design and performance of an inexpensive and lightweight 3D printed orthotic device featuring a wrist mechanism. The design is simple and utilizes twisted and coiled polymeric (TCP) muscles

This paper presents an experimental investigation carried out to study the performance of electrical discharge machining (EDM) using water as dielectric. This experimentation was performed using different types of water as dielectric, several electrode materials and two different workpiece materials. The electrode materials used in the experimentation were bronze, brass, copper, aluminium and steel; and the workpiece materials used were ASTM A36 mild (low-carbon) steel and D-2 tool steel. A new desktop size EDM machine to perform the experiments was designed and is presented in this paper. Aft

Flip-chip technology has been introduced in recent years which accommodate the ever increasing demands for higher performance and I/O density, while achieving smaller form factor and offering a cost effective solution. As the industry moves toward the 65nm and 45nm technology node, die sizes require a significant reduction while accommodating the need for tighter and finer pitches. For decades, the C4 process has served as the main interconnect method in the flip-chip package. But with bump pitches shrinking, the solder bump based C4 process is facing challenges in terms of reducing pitch and
