Secretion Rates and Chemical Composition of Oviduct and Uterine Fluids in Ewes (1969)

Oviduct and uterine fluids were collected by cannulation for 33–57 days from three nonpregnant ewes during the breeding season. Secretion rates of oviduct fluids were 1.35± 0.08 ml/24 hr from both oviducts during the 4-day period following the onset of estrus, and 0.45 ± 0.04 ml/24 hr during the remainder of the estrous cycle. Secretion rates of uterine fluids during the same two periods were 3.43 ± 1.59 and 0.59 ± 0.31 ml/2 uterine horns/24 hr, respectively. Oviduct fluids contained lower (p < .05) concentrations of dry matter, lipid choline, and glycerophosphoryl choline (GPC) diesterase activity than uterine fluids. Concentrations of protein, glucose, lactate, citrate, and lipid aldehyde did not differ significantly between the two fluids. Concentrations of lipid choline and GPC diesterases increased (p < .05) near estrus in oviduct and uterine fluids. Concentrations of other components did not vary widely between the stages of the estrous cycle, even though secretion rates changed markedly.
Synthesis of 1-Isopropylamino-3-(pyrazolo[1,5-a]pyridyloxy)-2-propanols (1996)

Treatment of the 4-hydroxypyrazolo[l,5-alpyridine with glycidyl tosylate in the presence of base, followed by reaction with isopropylamine gave 1-isopropylamino-3-(pyrazolo[l,5-a]py-I.In a similar manner, 1-isopropylamino-3-(pyrazolo[l,5-alpyrid-6-and 1isopropylamino-3-(pyrazolo[l,5-a]pyrid-3-yloxy)-2-propanol were also prepared.Pindolol (I),' 3-(4-indoly1oxy)-1-isopropylamino-2-propano, is an important member of 3aryloxy-1-isopropylamino-2-propanol derivatives, which are known to possess a potent P-blocking activity.Pyrazolo[l,5-a]pyridine* is one of aza-analogue of indole but the chemical reactivity3 and biological activity4 of pyrazolo[l,5-alpyridine derivatives are not well studied comparing with those of indoles.1; Pindolol Pyrazolo[l,5-alpyridine 2 -CH(OH)CHzNHCH-), 4.0-4.2(3H, m, -OCHzCH(OH)-), 6.39 (lH, br d, J=7Hz, H-5), 6.62 (lH, dd, J=2.5, 1 Hz, H-3).6.64 (lH, t, J=7 Hz, H-6), 7.87 (lH, d, J= 2.5 Hz, H-2).8.14 (lH, dt, J=7, 1 Hz, H-7).Anal.Calcd for C13H19N302: C, 62.62; H, 7.68; N, 16.86.Found: C, 62.76; H, 7.58; l-Isopropylamino-3-@yr~~olo[l,5~pyrid-6-yoxy)-2-propanol(8b) Using a procedure similar to that described for the preparation of Sa, Sb (78%) was obtained from 7b, mp 122-123°C (from ethyl acetate).Ir (nujol): 3240 cm-1; l ~-n m r (CDC13) 6: 1.10 (6H, d, J=6 Hz, CH3x2).2.1-2.35(ZH, br s, NH and OH), 2.7-2.95(3H, m, -CH(OH)CH2NHCH-), 3.95-4.1 (3H.m, -OCHzCH(OH)-), 6.43 (lH, d, J=2.5 Hz, H-3), 6.96 (lH, dd, J=9.5, 2 HZ, H-5), 7.42 (lH, d, J=9.5 Hz, HA), 7.85 (lH, d, J=2.5 Hz, H-2), 8.1-8.15(lH, m, H-7).Anal.Calcd for C13H19N302: C, 62.62; H, 7.68; N, 16.86.Found: C, 62.67; H, 7.62; N, 16.89.l-Isopropylamino-3-@yr~~olo[l,5alpyrid-3-yo)-2-ppo (Sc)Using a procedure similar to that described for the preparation of 8a, 8c (94%) was obtained from 7c, mp 66-68°C (from n-hexane).Ir (nujol): 3260 cm-l; l ~-n m r (CDC13) 6: 1.10 (6H, d, J=6 Hz, CH3x2), 2.0-2.3 (ZH, br s, NH and OH), 2.75-3.0(3H, m, -CH(OH)CHzNHCH-), 4.05-4.2(3H, m, -OCH2CH(OH)-), 6.39 (lH, br d, J=7 HZ, H-5), 6.62 (lH, dd J=2.5, 1 Hz, H-3), 6.64 (lH, t, 5=7 Hz, H-6).7.87 (lH, d, J= 2.5 Hz, H-2).8.15 (lH, dt, J=7, 1 Hz, H-7).Anal.Calcd for
Fast Barriers for Scalable ccNUMA Systems (2005)

The contributions of this paper are threefold. First, we identify and quantify the performance deficiencies of conventional barrier implementations when they are executed on real (non-idealized) hardware. Second, we propose a queue-based barrier algorithm that has effectively O(1) time complexity as measured in round trip message latencies. Third, we demonstrate how matching the barrier implementation to the way that modern shared memory systems operate can improve performance dramatically by exploiting a hardware write-update (PUT) mechanism for signaling. The resulting barrier algorithm only costs one serialized round trip message latency to perform a barrier operation across N processors. Using a cycle-accurate execution-driven simulator of a future-generation SGI multiprocessor, we show that with no special hardware support our queue-based barrier outperforms OpenMP's LL/SC-based barrier implementation by a factor of 7.9 on 256 processors. With hardware that supports a coherent PUT operation, our queue-based barrier outperforms OpenMP barriers by a factor of 94 and outperforms barriers based on SGI's memory controller-based atomic operations by a factor of 6.5 on 256 processors.
Photonic applications of snlphide glass optical fibres (1997)

Special Symposia Keynote Session and Announcement of the PhAST Innovation Award (2004)

Just as in Integrated Circuits, in Photonics, advances in semiconductor technology drive products to lower costs, higher reliability, increased performance and higher efficiency. However, it takes money to advance manufacturing technology and large sales volume is needed. Sales volume is, in turn, driven by applications. During the symposium, we will review advances in near-infrared detectors and imaging, as well as new applications. We will also discuss super-efficient lasers, tunable lasers and vertical-cavity lasers products and their applications.
Sampled Nonlinearly-Chirped Fiber-Bragg-Grating for the Tunable Dispersion Compensation of Many WDM Channels Simultaneously (1999)

We have fabricated and characterized a tunable dispersion compensator that utilizes a specially designed sampled nonlinearly-chirped FBG which is suitable for WDM channels. The dispersion can be tuned from -200 to -1200 ps/nm. We experimentally demonstrated tunable dispersion compensation using the sampled nonlinearly chirped FBG in a 10-Gb/s WDM system. All three channels achieve BER=10−9 after both 60 km and 120 km of SMF by tuning the dispersion of the grating between -550 and -1100 ps/nm.
Integriertes Organisch-Chemisches Praktikum (I.O.C.-Praktikum) (2007)

Das hier vorgestellte Praktikum basiert auf dem von S. Hünig, G. Märkl und J. Sauer aus dem Jahr 1979. Integriert bedeutet, dass es sich nicht um ein klassisches Kochbuch handelt. Alle Aspekte, die bei einem Experiment in wissenschaftlichem Neuland in Betracht gezogen werden müssen, sind bereits in den Praktikumsversuch integriert. Spektroskopie, Diskussion der relevanten Spektren im Hinblick auf mehrere denkbare Reaktionsprodukte, theoretische Durchdringung der verschiedenen Reaktionsabläufe, letztlich Formulierung der Reaktionsmechanismen. Das I.O.C.-Praktikum ist nach Reaktionstypen gegliedert, die Versuche in den Unterkapiteln sind - sofern möglich - zielführend zum Reaktionsmechanismus miteinander vernetzt. Dieser Aufbau soll ebenfalls forschungsnahe Bedingungen simulieren. Im ausgedruckten Text werden nach allgemeinen Kapiteln (Sicherheit, Standard-Reaktionsapparaturen, Musterversuch mit Betriebsanweisung, Musterprotokoll) die Titel der in den 7 Kapiteln mit 24 Unterkapiteln angebotenen 154 Versuche mit Formelbildern aufgelistet. Die einzelnen Kapitel werden in Übersichten theoretisch behandelt, in den Einführungen zu den Unterkapiteln wird die syntheseorientierte Chemie abgehandelt. Die Übersichten und Einführungen sind das Kernstück des gedruckten Textes, sie bieten ein Grobraster der organischen Chemie. Sie enthalten umfangreiche Literatursammlungen (Monographien, Übersichtsartikel, Primärliteratur), die deutlich über die Voraussetzungen für ein erstes organisches Praktikum hinausgehen, die aber dem Buch Nachschlagewert sichern. In den letzten Jahrzehnten haben der Schutz der Umwelt, die Sicherheit beim Umgang mit Chemikalien als Gefahrstoffen und beim Arbeiten im Labor immer größere Bedeutung erlangt. Chemische Praktika müssen dem Rechnung tragen. Versuche mit problematischen Chemikalien im Praktikum mussten ersetzt werden durch umweltfreundlichere, zugleich aktuelle und moderne Vorschriften. Zur Verringerung der Entsorgungsproblematik wurde die Zahl der eingesetzten Solventien auf wenige, nicht toxische verringert, die überdies durch Redestillation gereinigt und wieder verwendet werden können. Die Beschreibung der eingesetzten Reaktionsapparaturen wird durch einfache Symbole visualisiert, welche die Funktionstüchtigkeit der Apparaturen sicherstellen sollen. Am I.O.C.-Praktikum hat eine Gruppe um Prof. Sustmann (Essen) in Kooperation mit den Regensburger und Würzburger Autoren und mit finanzieller Unterstützung der BfU mitgearbeitet.
Synthesis and self‐assembly of amphiphilic macrocyclic block copolymer topologies (2011)

Abstract We demonstrated the synthesis of miktoarm star block copolymers of AB, AB 2 , and A 2 B, in which block A consisted of linear poly( tert ‐butyl acrylate) (P t BA) and block B consisted of cyclic polystyrene. These structures were produced using the atom transfer radical polymerization to make telechelic polymers that, after modification, were further coupled together by copper‐catalyzed “click” reactions with high coupling efficiency. Deprotection of P t BA to poly(acrylic acid) (PAA) afforded amphiphilic miktoarm structures that when micellized in water gave vesicle morphologies when the block length of PAA was 21 units. Increasing the PAA block length to 46 units produced spherical core‐shell micelles. AB 2 miktoarm stars packed more densely into the core compared to its linear counterpart (i.e., a four times greater aggregation number with approximately the same hydrodynamic diameter), resulting in the PAA arms being more compressed in the corona and extending into the water phase beyond its normal Gaussian chain conformation. These results show that the cyclic structure attached to an amphiphilic block has a significant influence on increasing the aggregation number through a greater packing density. © 2011 Wiley Periodicals, Inc.

Habilidade competitiva de plantas de arroz com biótipos de capim-arroz resistente ou suscetível ao quinclorac (2009)

Objetivou-se com este trabalho avaliar a habilidade competitiva de plantas de arroz cultivar BRS Pelota com biótipos de capim-arroz resistente ou suscetível ao herbicida quinclorac. Para isso, foi instalado experimento em casa de vegetação, em delineamento completamente casualizado com quatro repetições, sendo os tratamentos dispostos em esquema fatorial 2 x 6. As unidades experimentais constaram de vasos plásticos contendo 10 dm³ de solo, cujo pH e nível de nutrientes foram previamente corrigidos. Os tratamentos consistiram na competição entre uma planta de arroz, cultivar BRS Pelota, com populações (0, 1, 2, 3, 4 ou 5 plantas por vaso) dos biótipos de capim-arroz resistente (ECH-13) ou suscetível (ECH-12) ao herbicida quinclorac. As avaliações foram realizadas aos 40 dias após emergência, sendo avaliados; massa seca da parte aérea (MSPA), taxa de crescimento (TC), área foliar específica (AFE), razão de massa foliar (RMF), razão de área foliar (RAF) e índice de área foliar (IAF). A interferência no desenvolvimento do cultivar de arroz BRS Pelota foi proporcionalmente maior com o aumento da população de ambos os biótipos de capim-arroz. Os biótipos apresentaram, em geral, habilidade competitiva similar.

Das Fragment ist oben und unten unvollständig, doch sind beide Kanten so geradlinig, daß man den Verdacht haben muß, daß sie in moderner Zeit, beispielsweise von einem Händler, beschnitten worden sind. Links und rechts fehlt vom Text bis auf zwei Ausbrüche an den unteren Ecken nichts; Freiränder sind aber auch hier nicht erkennbar. Die Schrift verläuft quer zu den Fasern, das Blatt war daher wohl transversa charta beschrieben. Die Rückseite ist leer.
Total Syntheses of Spidamine and Joramine, Polyamine Toxins from the Joro Spider, Nephila clavata. (1996)

In order to confirm the structures of spidamine and joramine, identified from the venom of a spider (Nephila clavata), we convergently synthesized both compounds, which have a common side chain of N-(L-asparaginyl)-N'-(3-aminopropyl-β-alanyl)-1, 5-pentanediamine. A synthon of the common side chain was synthesized by starting with n-propanolamine which was converted to 7-azido-N-benzyloxycarbonyl-4-azaheptanoic acid N-hydroxysuccinimidyl ester. The ester was coupled with tert-butyloxycarbonyl-L-asparaginyl-1, 5-pentanediamine to give the synthon of the common side chain. In the final synthesis of spidamine, the synthon of the common side chain was reacted with 2, 4-dibenzyloxyphenylacetic acid N-hydroxysuccinimidyl ester, obtained by Willgerodt-Kindler reaction of 2, 4-dihydroxyacetophenone. The protected spidamine was catalytically hydrogenated to remove protective groups, affording spidamine itself in 13% yield from n-propanolamine. In the final synthesis of joramine, the synthon of the common side chain was reacted with 4-benzyloxyphenyl acetic acid N-hydroxysuccinimidyl ester. The protected joramine was also catalytically hydrogenated to produce joramine itself in 11% yield.The conformations of both synthesized compounds were analyzed by 1H-NMR and 13C-NMR. Their blocking activities on glutamate receptors were examined using labster neuromuscular synapses.
Peptide and protein analysis with mass spectrometry (2002)

Mass spectrometry (MS) is rapidly becoming a fundamental tool for biologists and biochemists in their efforts to characterize cellular function. Recent advancements in MS technology and front‐end methodologies, along with the completion of the human genome have greatly popularized its use by researchers for protein identification and characterization. This paper is a general overview of how mass spectrometry is being used for the analysis of peptides and proteins, focusing on its application to molecular weight determination. Sample preparatory and cleanup techniques used in our laboratory for protein and peptide analysis are provided, along with a discussion of data interpretation. The utility of mass spectrometry for protein and peptide analyses lies in its ability to provide highly accurate molecular weight information on intact molecules. The ability to generate such accurate information can be extremely useful for protein identification and characterization. For example, a protein can often be unambiguously identified by the accurate mass analysis of its constituent peptides produced by either chemical or enzymatic treatment of the sample. Furthermore, protein identification can also be facilitated by analysis of the protein′s proteolytic peptide fragments in the gas phase; fragment ions generated inside the mass spectrometer via collision‐induced dissociation (CID) to yield information about the primary structure and modifications. This overview describes how electrospray ionization (ESI) and matrix‒assisted laser desorption/ionization (MALDI) mass spectrometry is being used for peptide and protein characterization focusing on its application to molecular weight determination.
Evaluation of a high-performance object reuse dynamic memory allocation policy for C++ programs (2000)

The importance of dynamic memory management has increased significantly as there is a growing number of developments in object-oriented programs. Many studies show that dynamic memory management is one of the most expensive components in many software systems. In C++ programs especially, it tends to have prolific object creation and deletion. These objects tend to have short life-spans. This paper presents a dynamic memory allocation strategy to reuse these objects to speed up the object management. This object reuse scheme is implemented through the overloading C++ operators, new and delete. The C++ allocation patterns are studied thoroughly in this paper. Over 90% of objects are not bigger than 512 bytes and allocated prolifically. The proposed scheme is made feasible by reuse of these small objects. Our allocation scheme is simple and fast because it requires no splitting and no coalescing, and reduces the number of malloc() calls. It maintains its own free-list which is used for object reuse. The experimented results, based on the proposed allocation scheme, show that allocation speed is increased up to four times compared to other well-known algorithms. Our scheme is purely source-code oriented and built on top of malloc. Therefore, this approach is portable for application to existing code and safe to use with different mallocs.

Reflex chronotropic and inotropic effects of calcium channel-blocking agents in conscious dogs. Diltiazem, verapamil, and nifedipine compared. (1983)

In chronically instrumented, conscious dogs, rapid injection of equihypotensive doses of three calcium channel-blocking agents, verapamil (250 micrograms/kg), diltiazem (200 micrograms/kg) and nifedipine (50 micrograms/kg), produced disparate chronotropic and inotropic responses. Although they all decreased mean arterial pressure by about 10%, heart rate (93 +/- 4 beats/min) was markedly increased to 175 +/- 12 with nifedipine, to 163 +/- 15 with verapamil, and only slightly increased to 118 +/- 7 with diltiazem. Contractile responses measured before (left ventricular dP/dtmax, 2749 +/- 131 mm Hg/sec) and during left ventricular ejection (endocardial dimension dD/dtmax, 57 +/- 4 mm/sec) were increased by 24% and 14% with nifedipine, decreased by 26% and 22% with verapamil, and were unchanged with diltiazem. These chronotropic and inotropic responses to rapid intravenous administration of the three drugs were increased in a dose-dependent manner. Similar results also were observed after slow infusion of these drugs. To determine the extent to which autonomic reflexes participated in these cardiac responses, propranolol (0.5 mg/kg) or propranolol plus atropine (0.1-0.2 mg/kg) was administered prior to injection of each calcium channel-blocking agent. Propranolol abolished the positive inotropic response to nifedipine and potentiated the negative inotropic response to verapamil. Positive chronotropic responses to verapamil, nifedipine, and diltiazem were attenuated by propranolol plus atropine. These results suggest that equihypotensive doses of the three prominent calcium channel-blocking agents exert different degrees of autonomic reflex activation in awake, unsedated dogs. These reflexes, which modulate the direct effects of calcium channel-blocking agents on chronotropic and inotropic variables of the heart, may have important clinical implications.
