Abstract:
The song Anoman Obong by Ranto Edi Gudel is a song that uses Javanese. The song was arranged into a choir format by V. Mangunsongs. The arrangement by V. Mangunsongs in the song Anoman Obong is unique, one of which is the combination of story and tragedy in the form of a SATB choir. This study aims to describe the form of the arrangement of the Anoman Obong song composed by Ranto Edi Gudel arranged for the choir by V. Mangunsongs. This study uses a qualitative approach with content analysis methods. Data collection was carried out through observation, interview and documentation methods. Interviews were conducted with competent speakers in this field as well as the aranger of Anoman Obong's song, namely V. Mangunsongs aka Eko Agus Kandung. The stages in analyzing data are data reduction, data presentation and conclusion. The validity of the data was obtained through the data source triangulation technique. Overall, the Anoman Obong song composed by Ranto Edi Gudel arranged for the choir by V. Mangunsongs has 111 bar rooms. The form of this arrangement is including free or group forms with Introductions (bar 1-24) - Part A (bar 25-35) - Part A '(bar 35-43) - Part B (bar 44-58) - Interlude (bar 58 -66) - Transition (bar 67-86) - Part B '(bar 87-101) - Postlude (bar 101-111). In this work, there are many changes in tempo and dynamic signs to support the atmosphere of Anoman Obong's story and tragedy. The results show that this work can transform a previously simple vocal song into a more complex choir.

Abstract:
SummaryBlossom-end rot, a non-parasitic disease, was found to occur widely on some oblong varieties of watermelon, causing much damage in the southern region of Oman (Dhofar). Fruit contact with soil surface seems to be the major agent of blossom-end rot of watermelon, especially in the early stage. Incidence of watermelon blossom-end rot was apparently reduced by mulch using a mixture of dried grasses or coconut leaves.

Abstract:
In this study, micromorphology of an involucral bract and inner and outer dimorphic cypselae of the relict Amphoricarpos elegans, endemic from western Caucasus, is examined using a scanning electron microscope (SEM) and presented here for the first time. The middle involucral bract is nearly glabrous, with a reticulate-rugulose surface and an oblong-obtusate mucro. Both cypselae exhibit similar features, viz., narrowly oblong-cylindrical or obovate shape with more or less conspicuous longitudinal ribs, an adaxial detachment area, an asymmetrical carpopodium, absence of a pericarp crown and a barbate-aristate pappus made up of narrow, subulate, basally smooth and apically barbate bristles. However, some differences are evident. The outer cypsela is glabrescent and flattened, with an obscure outline of epidermal cells lacking an end wall and with a sunken periclinal surface and striatereticulate structure. Also, the outer cypsela has two entire, narrow, lateral wings, rounded above; and less numerous pappus bristles in one row. In contrast to this, the inner cypsela has a distinct outline of the epidermal cells, which are rod-shaped with a short acute end wall, a swollen periclinal surface and reticulate structure. The pappus of the inner cypsela possesses many more bristles organised in two rows (a biseriate pappus). Also, slightly pentagonal or round nectary remnants are found in the centre of the upper part of the inner cypsela. The taxonomic value of the analysed characters is briefly discussed.

Abstract:
Individual rows of irrigated, multi-row plots in a cotton breeding trial were harvested, and seed cotton yields were measured. Intergenotypic competition had occurred between the neighbouring long sides of the oblong plots. A further trial was conducted to measure competition in three- and four-row plots and to establish which system gave the least biased genotype means for lint yield (kg/ ha). However, competition in this experiment was minimal and both systems gave comparable results. The effect of bare ground at the end of plots was investigated. When bare ground, as compared to a discarded border, was present during their growing season, then end plants, for seven out of eight genotypes, were larger and plot yields were inflated. These results provided no conclusive evidence that current practices for field trials with cotton should be changed.

Abstract:
Sexual morph of Phaeoacremonium aureum was collected from a mangrove in Krabi Province, southern Thailand. It was linked to P. aureum based on the analysis of sequence data. The sexual morph is characterized by ascomata with relatively long conical necks and suballantoid to oblong, slightly curved ascospores, with rounded ends and small guttules at each end. Sexual morph of P. aureum differs from other species of Phaeoacremonium by having ascomata with relatively long (300–380 μm) conical necks and being saprobic on Rhizophora mucronata. This is the first record of Phaeoacremonium species from a mangrove habitat. We also provide a key to sexual morphs of Phaeoacremonium species.

Full text
Abstract:
The XMAP215 (Xenopus microtubule-associated protein 215) and CLASP [CLIP-170 (cytoskeletal linker protein 170) associated protein] microtubule plus end tracking families play central roles in the regulation of interphase microtubule dynamics and the proper formation of mitotic spindle architecture and flux. XMAP215 members comprise N-terminally-arrayed hexa-HEAT (huntingtin, elongation factor 3, the PR65/A subunit of protein phosphatase 2A and the lipid kinase Tor) repeats known as TOG (tumour overexpressed gene) domains. Higher eukaryotic XMAP215 members are monomeric and have five TOG domains. Yeast counterparts are dimeric and have two TOG domains. Structure determination of the TOG domain reveals that the six HEAT repeats are aligned to form an oblong scaffold. The TOG domain face composed of intra-HEAT loops forms a contiguous, conserved tubulin-binding surface. Nested within the conserved intra-HEAT loop 1 is an invariant, signature, surface-exposed tryptophan residue that is a prime determinant in the TOG domain–tubulin interaction. The arrayed organization of TOG domains is critical for the processive mechanism of XMAP215, indicative that multiple tubulin/microtubule-binding sites are required for plus end tracking activity. The CLASP family has been annotated as containing a single N-terminal TOG domain. Using XMAP215 TOG domain structure determinants as a metric to analyse CLASP sequence, it is anticipated that CLASP contains two additional cryptic TOGL (TOG-like) domains. The presence of additional TOGL domains implicates CLASP as an ancient XMAP215 relative that uses a similar, multi-TOG-based mechanism to processively track microtubule ends.

Full text
Abstract:
In Emlyn Williams's play,The Corn is Green(1938), an Englishwoman arriving in Wales is asked an important question: ‘Are you Church or Chapel?’ Since the seventeenth century, when non-Anglican places of worship made their appearance, this question has indeed been important, sometimes momentous. ‘Church’ has had one kind of resonance in religion, politics and society; ‘chapel’ has had another. Even in unreligious households, people may still opt for ‘church’ when the bread is cut (the rounded end) or ‘chapel’ (the oblong part). The distinction is far older than the seventeenth century, however, by at least five hundred years. There were thousands of chapels in medieval England, besides the parish churches, when religion is often thought of as uniformly church-based. Although these chapels differed in some ways from those of Protestant nonconformity, notably in worship, they also foreshadowed them. Locations, architecture, social support and even religious diversity are often comparable between the two eras. Arguably, the creation of chapels by non-Anglicans after the Reformation marked a return to ancient national habits.

Abstract:
Kein anderes Thema hat die nigerianische Literatur so dominiert wie der nigerianische Bürgerkrieg, in dessen Verarbeitung sich verstärkt auch Autorinnen einmischen. Die Dissertation evaluiert 34 Texte von 16 nigerianischen Autorinnen - 12 Romane und 22 Kurzgeschichten - und analysiert sie als Gesamtkorpus, in dem die Texte miteinander und mit der Männerliteratur einen Dialog um den Bürgerkrieg führen. Die Autorinnen wenden bei ihrem "war talk" literarische Strategien wie "re-reading" und "re-writing" an, das Neu-Lesen, Fort- und Umschreiben der Texte und Diskurse des "Zentrums", durch die nicht nur die Blindstellen eines von Männern dominierten literarischen Diskurses sichtbar werden, sondern durch die auch der Prozess des Aushandelns der Geschlechterverhältnisse sowie des Krieges selbst erfolgt, seiner Ursachen, Auslöser und Folgen. Die Autorinnen stellen den Krieg als "sexuelle Unordnung" dar, als Geschlechterkrieg. Die Untersuchung zeigt, dass bei der Verortung der Perspektive der Autorinnen neben Geschlecht, ethnischer Zugehörigkeit auch andere Faktoren, wie Alter, Race, Grad der Distanz oder Nähe etc. berücksichtigt werden müssen, um vorschnelle Festschreibungen zu vermeiden. Hierbei spielen die Paratexte eine wichtige Rolle, in denen die Autorinnen sich persönlich zum Krieg äußern. Die Arbeit bewegt sich an den Schnittstellen mehrerer Disziplinen: Literatur, Historiographie und Geschlechterstudien. In der Einleitung werden die theoretischen Prämissen im Kontext von Krieg, Geschlecht und literarischer Repäsentation behandelt. Das 1. Kapitel ist dem historischen Kontext des Bürgerkrieges, einschließlich der Rolle der Frauen darin gewidmet. Im 2. Kapitel geht es um die Darstellung des Krieges, des Selbst- und Feindbildes sowie der Zukunft. Das dritte Kapitel handelt von der Beziehung zwischen Bürger- und Geschlechterkrieg, vermittelt durch das Medium literarischer Text. Die Zusammenfassung der Ergebnisse und der Ausblick auf zukünftige Forschung erfolgt im Schlussteil. Der Anhang enthält ein vorläufiges Verzeichnis der gesamten Frauenliteratur über den nigerianischen Bürgerkrieg.
No other topic has dominated the Nigerian literature as much as the Nigerian Civil War and female authors increasingly interfere in its literary representation. The thesis evaluates 34 literary texts by 16 female Nigerian authors - 12 novels and 22 short stories - and analyses them as distinctive corpus whose individual texts are in a state of dialogue both with each other and with texts from male authors. The female authors use, in their "war talk", literary strategies like "re-reading" and "re-writing" of texts from the "Centre". On the one hand, these strategies enable them to make the blind spots of a male dominated literary discourse apparent/visible on the other hand, they facilitate the negotiation of gender relations and of the war itself, its causes, trigger points and consequences. The female authors represent war as "sexual disorder", as gender war. The study shows that in order to be able to locate an author''s perspective (and to avoid rash conclusions) it is essential to consider the different factors determining it - besides ethnicity and gender, also age, race, the grade of emotional involvement or distance etc. It is in this regard, where the paratexts play an important part, as in these authors express their personal views and comments on the war. The thesis is located at the interfaces of several disciplines: literary, historical and gender studies. The introduction deals with the theoretical backgrounds in the context of war, literary representation and gender. The first chapter is dedicated to the historical context of the Nigerian Civil War including the role of women. The second chapter looks at the paratexts, different representations of the war''s causes, the self-image, the enemy''s image and the future. The third chapter finally deals with the question how the relationship between Civil War and gender war is negotiated/conveyed through the medium of the literary texts. In the conclusion the results are summarized and prospects for future research are discussed. The appendix contains a preliminary bibliography of all literary texts on the Nigerian Civil War written by female authors.

Abstract:
He is indeed a familiar personality in classical literature and frequently appears in literary epigraphic and papyrological sources. His duties are fairly well defined and have been competently described on a number of occasions. Likewise, we know him from Rabbinic sources, in which he appears under the guise of different spellings and even different names. Here I shall try to sum up Rabbinic evidence on the subject and thus define the office and duties of the agoranomos in Roman Palestine. The notion of authoritative supervision of the weights and measures in use in a market is ancient and is found in Biblical law. Deuteronomy 25:14-15 prescribes that “Thou shalt not have in thine house diverse measures, a great and a small. But thou shalt have a perfect and a just weight, a perfect and just measure shalt thou have. . . .” Although this is formulated as a direct injunction upon the individual, clearly the practical implementation of such a commandment posits some kind of controlling authoritative framework. Tannaitic law (i.e., up to ca. 220 C.E.) exegetically expounds this latter verse as follows (Sifrei Deuteronomy, sec. 294): “[But] thou shalt have [a perfect and just weight]. . . .”—appoint an agoranomos for this (or according to some readings: for measures). Although this ruling is based upon the Biblical verse, the actual institution of the agoranomos is clearly Hellenistic in origin; the use of a Greek loanword, as apposed to some local (Hebrew or Aramaic) term, is ample testimony. From the Sifrei we learn of the agoranomos’ duty to control the standards of weights and measures in the market. Indeed, T. H. Dyer reminds us in his Pompeii (London, 1871) that in Pompeii “in a recess at the northeast end of the temple under the colonnade of the Forum stood the public measures for wine, oil, and grain. These consisted of nine cylindrical holes cut in an oblong block of tufa: There are five large holes for grain and four smaller ones for wine. The former had a sliding bottom that the grain when measured might easily be removed. The latter are provided with tubes to draw off the liquid. These measures were placed near the horrea or public granaries”.

Abstract:
Abstract The conventional gurneys used in hospitals to move patients from room to room have one main disadvantage: they are difficult to control. A typical gurney has a form of an oblong table moving on four castor wheels. The vehicle is difficult to maneuver, especially on corridor turns, and usually requires two operators — each at one end. Dr. J. Bleicher from the St. Joseph’s Hospital in Omaha, Nebraska suggested a new type of a self-propelled gurney which would be a cross-breed of a motorized wheelchair and a gurney. A new type of a gurney would have two additional wheels in the center of the gurney, each connected to a separate DC motor. The torques developed by the motors would be controlled by one operator using a joystick. Applying opposite torques to the controlled wheels would rotate a stationary gurney in place, or would curve the path of a moving gurney. The position of two additional wheels can be changed, so that the gurney can move sideways, translate in chosen direction or move along a curvelinear path. The work presented in the paper contains an analysis of the dynamics of such a gurney. A mathematical model of the vehicle was developed to check how much effort is needed on the part of the operator in straight path motion and during negotiating a corner. The most difficult part of the modelling was a proper description of forces and torques exerted by the ground on the wheels. The differential equations of motion of the gurney have been numerically integrated, and the dynamical response of the vehicle studied. The results of the computer simulation show a transient oscillatory response of the castor wheels (shimmying) which can be controlled by a proper choice of design parameters of the vehicle.

Abstract:
A variety of devices that help to prevent drops of spayed pesticides from getting into places that are difficult to reach (e. g. under the leaves of cultural plants of on the stem), is offered. Special devices Lechler DroplegUL are designed in a way that nozzles that are embedded in the end of the spraying pipe which is bended backwards, spray diagonally upwards. Data of the quality of spraying fluid by using various sprinklers in special devices Lechler DroplegUL is provided in the article. Two hydraulic flood nozzles Lechler 684.356.30X, mounted in a special holder TwinSprayCap were examined: pneumohydraulic twin flat spray air-injector nozzle Lechler DF 120-03 and hydraulic twin flat spray nozzle Lechler DF 120-02. A transverse repartition and a process of the formation of fluid drops, sprayed using different nozzles were examined. The results revealed that while spraying with a lower working pressure (e.g. 1.5 bar) with two hydraulic flood nozzles Lechler 684.356.30X that are placed in a special holder TwinSprayCap and embedded on a device Lechler DroplegUL, a majority of drops (evenly around 40 ml) get into stand trays that are in a setting place situated 70–110 cm behind the device Lechler DroplegUL, whereas at the approximate 40 cm area away from the setting place there are no drops of sprayed fluid at all. Having the working pressure increased to 3–4 bar, majority of drops (around 60 ml) get into the stend trays that are in a setting place situated 70–110 cm behind the device Lechler DroplegUL. Having the working pressure increased, an unsprayed area, which is situated around the setting place of the device Lechler DroplegUL, gets narrowed: a width of unsprayed area when spraying at the pressure of 2 bar was around 60 cm, whereas when the pressure was 3 bar and 4 bar, the area appeared to be only 20 cm. Circularly sprayed drops, depending on the working pressure, spread around in two strips of width from 1.4 to 1.8 m. An oblong flat flow of the sprayed fluid forms nearby the deflector and the maximum height of the rise of sprayed drops reaches 1.3–1.4 m.
