Education - Abstract
This historical overview traces the history of IASSW through portraits of the sequence of its presidents. The history of this organisation is not only connected with major phases of the history of the 20th century but also partly with my own history as a member and teacher of a historically rooted profession and discipline. I was inspired to commission this series of portraits by my numerous encounters with international colleagues and their rich and diverse contributions to the continuous development of our discipline.

Education - Abstract
In their recently published literature review of international social work (Homfeldt/Schneider 2006) the authors observe that, in Germany, internationalism does not always play the role that it should, given the increasingly global nature of society’s problems and responsibilities. ‘Although in the last ten years educational perspectives have become more international (focusing particularly on Europe), professional discussion is still largely confined to the national level’ (ibid., p. 6). This observation holds true not only for Germany but, in varying degrees, also for other countries, despite international congresses and problem-orientated discussions at European level. On the other hand, reciprocal understanding and openness have grown through comparative analysis, to the benefit of all participants. A growing understanding is now becoming more evident, arising from the need to introduce regulations on a multiplicity of social issues, not all directly to do with social work. With others, Walter Lorenz in particular pushed for this, demanding critical European activity in this field. Of the publications that accompanied this process Walter Lorenz’s ‘Social Work in a Changing Europe’ stands out. It first appeared in 1994 and has since been translated into several other languages. In 2006 came a second theoretically more substantial publication this time with the title ‘Perspectives on European Social Work: From the Birth of the Nation State to the Impact of Globalisation’. In this book he points critically and evocatively to social work’s roots in nation states but shows at the same time that purely national foundations for social policy and social work fail, on their own, to offer viable solutions in increasingly trans-national social arrangements.

Zusammenfassung Das Ziel vorliegender Untersuchungen war, im Schrifttum angegebene geeignete Me-thoden fur die Bestimmung des Nitratstickstoffs in pflanzlichen Futtermitteln zu uber-priifen und miteinander zu vergleichen. Hierbei wurden folgende Ergebnisse erzielt: Fehler von ± 2 %. Dieser Mesbereich wird bei der Verwendung von 1-, 2-, 4-Xylenol auf 0,03 bis 0,100 mg N03-N in 5ml bei einem Fehler von ± 2 % ein-geengt. 1 Der Nitratstickstoff kann sowohl in der Frischsubstanz als auch nach der Trock-nung an der Luft bei 60 ° C in der lufttrockenen Substanz analysiert werden. Wahrend des Trocknungsprozesses treten keine Nitratverluste auf. 2 Die verschiedenen Extraktionsmittel und die Art des Pflanzenauszuges sind ohne Einflus auf die Analysenergebnisse. 3 Fur die Bestimmung des Nitratstickstoffs wurden drei Methoden uberpruft, miteinander verglichen und Arbeitsvorschriften aufgestellt. 4 Die beiden kolorimetrischen Verfahren beruhen auf der Nitrierung von Xylenol in schwefelsaurehaltiger Losung. Bei der Verwendung von 1-, 3-, 4-Xylenol wird das gebildete Nitroxylenol mit Wasserdampf in eine Vorlage von Natronlauge uberdestilliert. Die Wasserdampfdestillation muste bei der Benutzung von 1-, 2-, 4-Xylenol durch eine atherextraktion ersetzt werden, da das hierbei entstandene Dinitroxylenol nicht mit Wasserdampf quantitativ fluchtig ist. Die Nitroxylenole losen sich im alkalischen Medium unter Bildung einer gelben Farbe. 5 Die photometrische Messung erfolgt mit dem Zeis'schen Photometer Elko II bei einer Schichtdicke von 1 cm unter Verwendung des Filters S 47 E. 6 Der Mesbereich fur die Nitratbestimmung mit 1-, 3-, 4-Xylenol umfast Konzen-trationen von 0,010 bis 0,400 mg NO3-N in max. 5 ml Losungsmittel bei einem 7 Bei der polarographischen Nitratbestimmung konnen Konzentrationen von 0,5 bis 5 γ bzw. 5 bis 50 γ NO3-N/ml bei einem mittleren Fehler von ± 2 % gemessen werden. Das Nitrat-Ion wird nach einer Reinigung der Pflanzenextrakte mit Wo-fatit F oder KPS 200 mit Uranyl-Leitsalz als Katalysator an der tropfenden Quecksilberelektrode reduziert. Als Analysengerat stand der Radiometer-Polaro-graph Type PO 3 zur Verfugung. 8 Auf Grund der Untersuchungen konnen alle drei Nitratbestimmungsmethoden fur die Pflanzenanalyse empfohlen werden, da bei einem Vergleich an verschiedenen Substanzen keine unterschiedlichen Analysenergebnisse erzielt wurden. Bei nitrat-armen Pflanzen sind jedoch die Bestimmung mit 1-, 2-, 4-Xylenol und die polaro-graphische mit einer Empfindlichkeitseinstellung von 1:100 vorzuziehen.

Hard and soft wheat flours, which were used in the study, resulted in good and poor quality chapatis respectively. Gluten was isolated and interchanged among the two whole wheat flours and studied by scanning electron microscopy for its influence on structural characteristics of dough and its relation to chapati-making quality. Microscopic observations clearly indicated that larger gluten strands covered starch granules in hard wheat flour dough, while gluten was short and starch granules exposed in dough prepared from soft wheat flour. Greater film forming ability of gluten in hard wheat flour dough manifested in long and bulky starch strands interwoven with protein matrix in its chapati crumb. Higher moisture retention and starch gelatinization as a consequence of greater film forming ability of gluten in hard wheat flour resulted in pliable and soft textured chapati.

A formal approach for the mission planning and control of unmanned aircraft is described. Linear hybrid automata are used to model the chosen aircraft, the resources needed to perform a mission and the environment in which the aircraft will operate. This mission model can be verified with respect to safety criteria, like not running out of fuel, or used to perform parametric analysis, allowing the instantiation of symbolic parameters in flight plans for specific missions. Later, during mission execution, an on-board flight controller is used to control the progress of the mission by reacting to relevant external and internal events.

Twenty flours from 16 different barley varieties cultivated in 1990 and 1992, and a Swedish reference flour, were fermented by Lactobacillus plantarum Al to sour doughs. Barley breads (40% barley/60% wheat flour) from each flour type were baked with and without an admixture of barley sour dough in order to investigate how the sour dough admixture would affect the baking properties. A trained panel carried out sensory evaluation by conventional profiling on breads made from three of the barley varieties and the Swedish reference flour, made with and without sour dough admixture. The barley varieties influenced both the sour dough properties and the properties of the barley bread. The PH of bread with sour dough ranged from 4.6 to 4.8 as compared to 5.4 to 5.6 in. bread without sour dough. The acidity of the breads with sour dough ranged from 4.1 to 5.0 mi NaOH/10 g bread crumb as compared to 2.4 to 3.6 in breads without sour dough. In 14 of the twenty bread types an addition of sour dough lowered the bread volume. Breads with a sour dough admixture scored higher for total taste and acidulous taste than breads without sour dough. The beta-glucan content of the flours had no significant influence on the sour dough or the sensory characteristics of the bread, except for the breadcrumb colour.

Zusammenfassung Die auswirkungen von Hydrokolloiden und Emulgatoren bein de Herstellung von Weizen-kastenbrot wurden bei zwei unterschiedlichen Mehlqualitaten wahrend der Tein- und Backphase, sowie bei der Brotlagerung verfolgt. Die Versuche wurden mathematisch durch einen erweiterten Faktorenversuchsplan uber multipolynomische Regressions-gleichungen unterstutzt. Insgesamt gingen von den Emulgatoren starkere Auswirkungen aus als von den Hydro-kolloiden. Emulgatoren verlangerten die Endgarzeit, verbesserten die Teigelastizitat und den Teigstand und erhohten den Ofentrieb und die Gashaltung, wobei sich der DAWE-Ester stets starker als die anderen Emulgatoren auswirkte. Hydrokolloide erhohten die Teigausbeuten und verringerten die Endgarzeiten, Gartoleranz und Gashaltevermogen wurden durch Hydrokolloide, auch in Kombination mit DAWE-Ester, vermindert. Nur Guarmehl erhohte den Ofentrieb und das Brotvolumen. Insgesamt erwies sich die Kombination Hydrokolloide/DAWE-Ester den anderen Kombinationen uberlegen.

The gelatinization characteristics of a cassava/corn starch based blend with relatively high moisture content during cooking extrusion were studied. The study was carried out by using Response Surface Methodology. The results showed that the die temperature Td (°C) was the main influencing factor for the starch gelatinization, and the feed rate of the materials Vf (g/min) was another minor one. Because of the high material moisture content during extrusion the moisture content Mc (%) influenced the gelatinization degree not so obviously. The residence time distribution of the mass during extrusion were studied as well as discussed as a influencing factor on the gelatinization results. Verkleisterungseigenschaften einer auf Cassava-/Maisstarke basierenden Mischung wahrend der Koch-Extrusion unter Anwendung der Response Surface Methodologie. Die Verkleisterungseigenschaften einer auf Cassavastarke basierenden Mischung mit relativ hohem Wassergehalt wahrend der Koch-Extrusion wurden untersucht. Die Forschung wurde nach der Theorie “Response Surface Methodology” durchgefuhrt. Die Ergebnisse zeigen, das die Dusen-Temperatur Td (°C) der Haupt-Einflusfaktor fur die Starkeverkleisterung war und die Dosierungsmenge Vf (g/min) ein zweiter. Aufgrund des hohen Wassergehaltes wahrend der Koch-Extrusion beeinflust der Wassergehalt Mc (%) die Verkleisterungseigenschaften nicht so stark. Die Verteilungen der Verweilzeit wurden untersucht und als Einflusfaktor auf die Verkleisterungsergebnisse diskutiert.

In the August of 2002, the Consumer Healthcare Products Association (CHPA) member companies were asked to assist the healthcare industry in addressing the lack of stability guidelines that were directly applicable to Over-the-Counter (OTC) monograph drug products. A Stability Working Group (SWG) was formed in May 2003 with experts from the following companies: Johnson & Johnson, Colgate-Palmolive Company, Novartis Consumer Health, Inc., McNeil Consumer Healthcare, Schering- Plough HealthCare Products, Inc., Bayer HealthCare, LLC, Purdue Pharma, The Procter & Gamble Company, Perrigo Company, and a CHPA facilitator. The SWG set out to develop a “white paper” document that would provide a science-based, industry recommended, best practice and minimum requirements for the development of OTC monograph drug products in the United States that are not regulated by an NDA/ANDA.

The modern consumer is very much interested in healthy food. The reason is that a special group of consumers is focusing more and more attention on health and nutrition problems. Further, there is increased emphasis on education in food science at universities as well as polytechnics. For some years worldwide dietary goals are published with the intention to reduce nutrition-based sickness. For the first time in our nutrition report 1988, clear proposals for optimal nutrition were formulated.

Friedrich W. Seibel, Walter Lorenz, and Günter J. Friesenhahn
- Abstract
Die europaische bzw. die internationale Dimension war fur die Soziale Arbeit schon von Anfang an von groβer Bedeutung, sowohl in theoretischer als auch in professioneller Hinsicht. Man konnte sagen, dass ohne Internationalisierung sich die Soziale Arbeit weder zu einer anerkannten wissenschaftlichen Tatigkeit, noch zu einer Profession hatte entwickeln konnen. Dies war vor allem wahrend der Zeit der Etablierung von Studiengangen in den 20er Jahren des vergangenen Jahrhunderts in Europa aktuell, als zumindest die treibenden Krafte in dieser Bewegung die Bedeutung internationaler Zusammenarbeit erkannten und in einer Serie von entsprechenden Kongressen und in der Grundung internationaler Organisationen zur Forderung sozialer Innovationen zum Ausdruck brachten. Das Werk, das diese erste Phase auf einen Hohepunkt brachte, die umfassende Studie aller Bildungseinrichtungen der Sozialen Arbeit weltweit von Alice Salomon (1937), verfehlte aber aufgrund der von Hitlerdeutschland ausgehenden nationalistischen Anfeindung und personlichen Verfolgung fuhrender Vertreterinnen der Sozialen Arbeit seine Wirkung. Diese Phase war von Respekt gegenuber der existierenden Vielfalt und den unterschiedlichen Entwicklungsstufen und Entwicklungstempi der Sozialen Arbeit in den entsprechenden Landern gekennzeichnet, gleichzeitig aber vom Willen, aus dieser Vielfalt ein gemeinsames Projekt zu gestalten.

The comparison of starch granule deformation and extent of starch gelatinization in a few common Indian unleavened flat breads (Chapati, Parontha and Poorie) was made. The starch granule swelling was evaluated by scanning electron as well as polarized light microscopy. The peak viscosity in Haake rotary viscosimeter and hydration capacity were used for comparing the extent of starch gelatinization in crust and crumb of these baked products. Although a few of the starch granules on the outside of crust, maintained a weak outline those in the crumb area gave only a matrix of gelatinized starch. The extent of starch gelatinization was reflected by the related increase in hydration capacity of these products. However, the peak viscosity values were found to be inversely related to the extent of starch gelatinization. As compared to crumb, a higher extent of browning was observed in the crust. Water absorption, type of cereal, mode and efficiency of heat transfer were found to control the extent of starch gelatinization in these baked products. Verkleisterung der Starke wahrend der Herstellung von ungesauerten indischen Flachbroten. Es wurden vergleichende Untersuchungen uber die Deformierung der Starkekorner und den Grad der Starkeverkleisterung in einigen nicht gelockerten indischen Flachbrotsorten (Chapati, Parontha und Poorie) durchgefuhrt. Das Quellen der Starkekorner wurde mit Hilfe der Rasterelektronenmikroskopie und Lichtmikroskopie beobachtet. Zum Vergleich des Grades der Starkeverkleisterung in der Kruste und Krume der Flachbrote wurden die maximale Viskositat im Haake-Roationsviskosimeter und das Wasserbindevermogen herangezogen. Obgleich die Starkekorner im auseren Teil der Kruste noch deutlich sichtbar waren, zeigten sie in der Krume eine 100% ige Verkleisterung. Der Grad der Starkeverkleisterung zeigte sich auch im Anstieg der Wasserbindung der gebackenen Produkte. Die maximale Viskositat zeigte eine entgegengesetzte Relation zur Starkeverkleisterung. In der Kruste wurden deutlichere Braunungsreaktionen festgestellt. Der Grad der Starkeverkleisterung in diesen indischen Flachbrotsorten hangt sowohl von der Wasseraufnahme und der Getreideart als auch von der Art und Wirkung der Temperaturubertragung beim Backen ab.

Background: Wound management in open pelvic fractures has used fecal diversion, debridement, and closure by secondary intention to prevent pelvic sepsis. Colostomy care and takedown adds to the morbidity and resource utilization of this approach. We reviewed our experience to determine if a selective approach to fecal diversion based on wound location was possible. Methods: Retrospective analysis of patients admitted to a Level I trauma center during an 8-year period. Fractures were classified as open if the fracture was in continuity with the wound. Wounds were classified as perineal if they involved the rectum, ischiorectal fossa, or genitalia, and as nonperineal if they involved the pubis anteriorly, iliac crest, or anterior thigh. Pelvic sepsis was defined as cellulitis, fasciitis, or infection of a pelvic hematoma. Diversion consisted of loop or end colostomy. Results: Eighteen patients with open fractures were identified. Four died from closed head injury and blood loss. The remaining 14 were treated as follows. Five patients with perineal wounds had diversion of their fecal stream. Their Injury Severity Score was 34 ± 8.3 and their Revised Trauma Score was 7.69 ± 0.15. No patient developed pelvic sepsis. Nine patients with nonperineal wounds did not undergo diversion. Their Injury Severity Score was 28.6 ± 5.3 and their Revised Trauma Score was 7.36 ± 0.45. No patients developed pelvic sepsis in the nondiverted group. Conclusion: No patients with anterior wounds and an intact fecal stream developed pelvic sepsis. Colostomy may not be necessary in all patients with open pelvic fracture. Protocols using fecal diversion based on wound location appear to be safe and may decrease resource utilization and subsequent morbidity related to colostomy closure.

A method for the measurement of human parathyroid hormone fragment 1-34 (PTH1-34) in dog plasma was developed by modification of a commercially available immunodiometric assay (IRMA) designed for the determination of rat PTH1-34 in serum. Major modifications were made to the assay in order to circumvent significant problems encountered during the validation of the IRMA. PTH1-34 was found to be highly unstable in both rat serum and dog serum and plasma at room temperature, in contrast to literature reports. The addition of a protease inhibitor cocktail to serum or plasma samples was necessary to prevent in-vitro proteolytic degradation of human PTH1-34 prior to analysis. Additionally, plasma was chosen over serum as the sample matrix to expedite the separation of samples from cells, minimizing proteolytic degradation prior to the addition of cocktail. Finally, the reported 100% cross-reactivity between rat and human PTH1-34 was found to be only 65%; therefore, a human PTH1-34 standard was substituted for the rat standard. These modifications allowed the accurate measurement of human PTH1-34 in plasma obtained from dogs dosed intravenously and subcutaneously with human PTH1-34 using a commercially available kit.

It is believed that the Egyptians discovered bread baking.1 Mural paintings show that sourdough was already used in Egypt as early as the 13th century bc. Findings from eastern Mediterranean regions suggest that bread baking was already known around 1800bc. From Egypt, the art of breadmaking came to Israel and then to Greece. Around 776bc the conclusion of the Olympic Games was celebrated with a feast that included bread made from wheat and barley. In Greece leavening of the bread was achieved with sourdough or soda; a special bread cult existed and Demeter, the goddess of bread, was revered.

Im Feldversuch wurde C-14 Chlorcholinchlorid Weizenpflanzen appliziert und dessen Schicksal wahrend der Kornreife untersucht. Radioaktivitat wurde teilweise im Lecithin und Lysolecithin gefunden. Daneben fand sich auch radioaktives Cholin. Anhand von Keimungsversuchen wurde gezeigt, das CCC zwar eine Erhohung der Chlorophyllmenge bewirkt, sonst aber keinen Einflus auf die Bildung von β-Carotin, Lutein, Lutein-epoxid, Violaxanthin und Neoxanthin sowie Galaktosyldiglyceriden und Phosphatiden hat. Somit kann eine Beeinflussung der Photosynthese durch CCC in den fruhen Stadien des Pflanzenwachstums ausgeschlossen werden. Studies on the Action of 2-Chlorotrimethyl Ammoniumchloride (CCC) on the Wheat Plant In field trials C-14 chlorocholinechloride was applied to wheat plants and its fate was studied during ripening of wheat. Radioactivity was found partly in lecithin and lysolecithin. In addition, radioactive choline was found. Based on germination studies, it was shown that CCC increases the amount of chlorophyll, however it has no influence on the formation of β-carotene, lutein, luteinepoxide, violaxanthine and neoxanthine as well as galactosyl diglycerides and phosphatides. Therefore, in the early stages of plant growth CCC does not appear to influence the photosynthesis.

Medicine (miscellaneous) ,Biochemistry ,Food Science - Abstract
Unter Verwendung eines Creusot-Loire Doppelschnecken-Extruders (Typ BC 45) wurden Sojaschrot und Roggenvollkornschrot bei unterschiedlichen Prozesparametern (12 % und 18 % Wassergehalt im Rohmaterial, 129 °C und 165 °C Massetemperatur bei Sojaschrot, 12 % und 18 % Wassergehalt im Rohmaterial und 165 °C Massetemperatur bei Roggenvollkornschrot, Schneckenumdrehungsgeschwindigkeit fur alle Proben 150 U/min) zu Extrudaten verarbeitet. Die ernahrungsphysiologische Proteinqualitat (scheinbare Proteinverdaulichkeit PV, Nettoproteinverwertung NPU und Biologische Wertigkeit BW) der Extrudate wurde im Stickstoffbilanzversuch an wachsenden Ratten gepruft. Im Vergleich zum unbehandelten Ausgangsprodukt wurde keine Verminderung der PV und der NPU in Sojabzw. Roggenvollkornschrotextrudaten beobachtet. Die Extrusion von Sojaschrot bei 165°C und 18 % Wassergehalt bewirkte eine geringe, aber signifikante Herabsetzung der BW von 68 % auf 64 %. Ein geringerer Wassergehalt in der Rohware (12 %) bewirkte eine leichte Erhohung der PV in Sojaextrudaten und der NPU und BW in Roggenvollkornschrotextrudaten.

Wheat starch was liquefied to DE 25–30 employing heat stable α-amylase and twin-screw Werner & Pfleiderer Continua 58 HTST-extruder. Most significant reduction in batch saccharification time was obtained when starch was liquefied as a slurry containing 60% water at 120°C mass temperature, feed rate 1 500 g min−1, screw rotation rate 250 min−1, and 0.9% (w/w, d.s.) Novo Termamyl 120 L α-amylase was added immediately after initiation of gelatinization in the extruder. Saccharification was carried out at 60°C employing 0.36% (w/w, d.s.) Novo glucoamylase 150 L to reach a DE 96 in 22 h. Best total conversion was, however, obtained when also saccharification was initiated in the extruder by adding glucoamylase just before the die element, after lowering mass temperature to 60°C, and by allowing the saccharification to continue at 60°C after extrusion processing to reach a DE 94 in 5 h and DE 97 in 21 h. Enzymatische Starkekonversion in einem Twin-Screw HTST-Extruder. Weizenstarke wurde bis zu einem DE-Wert von 25–30 DE verflussigt, unter Verwendung hitzestabiler α-Amylase und unter Einsatz eines kontinuierlich arbeitenden Doppel-Schnecken-Extruders deutscher Bauart. Die im Behalter-Verfahren durchgefuhrte Starkeverzuckerung ergab eine signifikante Reduktion der Verzuckerungszeit, besonders dann, wenn die Starke als Starkemilch mit 60% Wassergehalt bei 120°C Massetemperatur, eine Einspeisungsrate in den Extruder von 1 500 g/min und einer Umdrehungszahl der Doppelschnecken von 250 U/min verflussigt wurde und man Novo-Termamyl 120 L-α-Amylase in einer Menge von 0,9% (w/w, TS) so hinzufugte, das der Eintritt des flussigen Termamyls direkt nach Beginn der Starkegelatinierung im Extruder erfolgte. Die Verflussigung der Starke wurde bei 60°C und bei Anwendung von 0,36% (w/w, TS) Novo-Glucoamylase 150 L bis zum Erreichen eines DE-Wertes von 96 in 22 h durchgefuhrt. Die beste Starkeverflussigung bzw. -verzuckerung wurde jedoch dann erreicht, wenn man die Verzuckerung durch Zugabe von Glucoamylase unmittelbar vor die Scherelemente vor der Extruderduse einpumpte und auserdem die Massetemperatur bis auf 60°C absenken konnte und Vorsorge dafur traf, das die Verzuckerung bei 60°C nach dem Extrusionsprozes kontinuierlich fortlaufen konnte, bis ein DE-Wert von 94 in 5 h und ein DE-Wert von 97 in 21 h erreicht war.

The effect of various processing methods used for the production of dry flatbread from ground whole rye on the nutritional protein quality were investigated by means of the nitrogen balance method in growing rats. The following products were tested: untreated ground whole rye, baked crisp bread, extruded flatbread without and with the addition of 2.5% and 5.0% of saccharose. The apparent protein digestibility (PD) of the 5 samples varied between 69% and 72% and was neither affected by the method of processing nor by the difference in sugar content. Compared to the untreated raw material (NPU = 41%; BV = 59%) net protein utilization and biological value in crisp bread baked by the traditional method (NPU = 35%; BV = 48%) and in extruded flat bread with 5% sugar (NPU = 35%; BV = 51%) were significantly reduced (P less than 0.05). In extruded flatbread without and with 2.5% sugar, NPU and BV of the raw material were essentially maintained. The results indicate that in comparison with the baking process the extrusion of flatbread is more suitable to protect the protein quality. The addition of more than 2.5% sugar caused protein damage in extruded flatbread, presumably as a result of Maillard reactions.

5′-nucleotidase was demonstrated at the fine structural level in the stratum intermedium and ameloblasts of the first mandibular molars of CD-1 mice. The enzyme was localized with the Wachstein & Meisel (1957) method along the plasma membranes of the cells of the stratum intermedium and ameloblasts. While 5′-nucleotidase was present throughout the stratum intermedium, only the proximal region of the plasma membranes of ameloblasts was demonstrably active for this enzyme. 5′-Nucleotidase has been implicated in transport of metabolites across cell membranes, and its localization in the present study supports this implication as well as the transport functions of the stratum intermedium and the stratum intermedium-ameloblastic interface.

ATPase activity in the developing first mandibular molar of the mouse was demonstrated at the electron microscopic level with the method of Wachstein & Meisel (1957). It was localized along the cell surfaces of the ameloblast and stratum intermedium interface, the stratum intermedium and the stellate reticulum. The ATPase final reaction product was also present at the cell membranes of the proximal region of adjacent ameloblasts and extended to the level of the nuclei. The demonstration of ATPase mainly on the plasma membranes was similar to the observations by other investigators of various non-odontogenic cell types involved in the exchange of materials across plasma membranes.

The sticking probability of sputtered Cu, Ag and Au at collector foils was studied at 400 keV primary ion energy. It was observed (i) that a sizable fraction of the impinging material is reemitted, and (ii) that this fraction depends on the amount of material accumulated on the collector for Au, and Ag, but not for Cu. Interesting effects were observed for sputtering of a multicomponent target (Cu-Ag-Au). It is suggested that resputtering by reflected primary ions and selfsputtering by sputtered particles arriving at the collector play a major role for the reemission effect.

This paper presents some of the results from a survey of the use of standardized tests in junior colleges. Testing practices and problems related to the use of tests for guidance purposes are emphasized. The findings suggest that junior colleges are making substantial use of a variety of standardized tests primarily for guidance purposes. Problems in using the tests are being experienced, however, because of the inappropriateness of many tests, the scarcity of research evidence indicating how best to use the test results, the unavailability of tests designed to meet the specialized needs of junior colleges, and the lack of personnel with sufficient measurement training or experience.

C. W. Seibel
- Abstract
The production of helium for commercial use is of particular interest at this time since it had its inception in the State of Texas and has been carried on chiefly in that state ever since. The development of helium production is an excellent example of how American engineers attempt the seemingly impossible—and win. It also demonstrates the rapidity with which an almost hopeless undertaking can be completed when a determination really has been made to do so and the necessary funds are available. In this paper are outlined the early history of helium production, the steps in the necessary preliminary research, and how the data were applied. Early repurification plants are described, and facts given concerning the present Amarillo plant.
