Studies have been made on the morphology of the microfilariae of Onchocerca gibsoni Cleland & Johnston, and 0. gutturosa Neumann. Examinations were initially made on larvae emerging from dissected female worms, and later, on larvae recovered from the skin. No differences in either morphology or body length measurements were detected between the skin-inhabiting and freshly emerged larvae of each species. The form, size, and arrangment of the caudal and cephalic nuclei were found to vary widely within each species. Of the many measurements investigated only that of body length had any taxonomic value. Skin-inhabiting microfilariae of 0. gibsoni had a body length of 240- 280 � (mean 266 �), whereas those of 0. gutturosa measured only 200-260 � (mean 224.5 � ), the difference between the means being highly significant.

AbstractWe present the results of a large-scale corpus-based comparison of two German event nominalization patterns: deverbal nouns in -ung (e.g., die Evaluierung, ‘the evaluation’) and nominal infinitives (e.g., das Evaluieren, ‘the evaluating’). Among the many available event nominalization patterns for German, we selected these two because they are both highly productive and challenging from the semantic point of view. Both patterns are known to keep a tight relation with the event denoted by the base verb, but with different nuances. Our study targets a better understanding of the differences in their semantic import.The key notion of our comparison is that of semantic transparency, and we propose a usage-based characterization of the relationship between derived nominals and their bases. Using methods from distributional semantics, we bring to bear two concrete measures of transparency which highlight different nuances: the first one, cosine, detects nominalizations which are semantically similar to their bases; the second one, distributional inclusion, detects nominalizations which are used in a subset of the contexts of the base verb. We find that only the inclusion measure helps in characterizing the difference between the two types of nominalizations, in relation with the traditionally considered variable of relative frequency (Hay, 2001). Finally, the distributional analysis allows us to frame our comparison in the broader coordinates of the inflection vs. derivation cline.

abstract The European records from distances 36°-50° of the deep Hindu Kush earthquake of March 4, 1949 were studied. The many clearly recorded deep-focus reflections lend to the records a characteristic appearance which is repeated in many other shocks from the same focal region. The ratios of the amplitudes of these phases vary somewhat from one shock to another. In the shock here considered sP and sPP are exceptionally large at most stations; in the Italian stations they are not so large, while pP is a clear phase. pP is not very well defined at most other stations. Most of the 1949 records were from the old type long-period instruments having their highest magnification for periods from about 5 sec to 12 sec. Present day instruments of quite short or of very long proper period while admirable for many purposes do not record waves in this period range very well and therefore do not produce a satisfactory picture of the forerunners of earthquakes. The difference between the records obtained on different instruments is illustrated. It is shown in examples that the amplitude ratio PP:P may differ strongly at the same epicentral distance and also that pP may vary greatly with azimuth. The deficiency of station readings is noted. Travel times and their residuals are tabulated and travel times plotted versus epicentral distances.

It is now over 15 years since Hilary Putnam first urged that we take the “narrow path” of internal realism as a way of navigating between “the swamps of metaphysics and the quicksands of cultural relativism and historicism” (1983, p. 226). In the opening lines of the Preface to Realism with a Human Face, a collection of Putnam's recent papers edited by James Conant, Putnam reaffirms his allegiance to this narrow path, unmoved by Realist murmurings from the swamps and laconic Rortian suggestions that only the quicksands are a proper metaphilosophical abode for those willing to confront our lack of epistemological and metaphysical foundations. If there are changes to be discerned in these writings, Putnam avers, they pertain only to the burden allotted to different considerations in the overall economy of his argument: “It might be said that the difference between the present volume and my work prior to The Many Faces of Realism is a shift in emphasis: a shift from emphasizing model-theoretic arguments against metaphysical realism to emphasizing conceptual relativity” (p. xi).

This paper is about my latest book on Heidegger’s non-public writings on the event. It begins with a discussion of Contributions to Philosophy (Of the Event) and ends with The Event, spanning roughly the years 1936 to 1941. I pay primary attention to shift of attunements, concepts, and movement of thought in these volumes. Thereby a narrative emerges that traces a shift from a more Nietzschean pathos emphasizing the power of beyng to a more mystical approach in which Heidegger thinks “the beingless,” “what is without power,” and speaks of originary thinking as a thanking rather than a questioning. The shift begins to happen in 1939, the year World War II broke out but becomes clearly visible in 1940 in the volume On Inception (GA 70). Heidegger’s path of thinking is one of downgoing into the most concealed dimension of the truth of beyng and an attempt at thinking more radically without primacy of the human being. Among the many questions my book engages, I am focusing especially on the articulation of both the difference and simultaneity of beyng and beings in relation to attunement, body, history, and Heidegger’s errancies.

This chapter discusses how social psychology can offer theoretical contributions for a better understanding of the relations between the institutional and public spheres and how this may impact change in ecological matters. First, it introduces the difference between natural and agreed—or chosen—limits to human action and draws on Sophocles’s Antigone to illustrate this and discuss how legitimacy has roots in the many heterogeneous values of the public sphere/consensual universe, while legality arises from the institutional/reified sphere. Recalling some empirical research in the area of social studies of sustainability, it then shows how a social representations perspective can help us understand the dynamic and interdependent relations between the institutional or reified sphere and the consensual or common sense universe—and their implications for social change and continuity.

The study was conducted to know the diversity of Chiropterans as well as their status and morphometric measurements in Jahangirnagar University campus between July, 2014 and April, 2015. Eight species of bats from three families were identified where Common Pipistrelle (Pipistrellus pipistrellus) and Pouch Tomb Bat (Saccolaimus saccolaimus) were recorded for the first time in Bangladesh. A total of 31bat individuals of 8 species were captured during 15 netting nights for morphological studies. Skull preparation was carried out for taking cranial measurements to identify the Pipistrelle species. No roosting colony of Pteropus gigantius was found in the study area but it visits the area only for foraging while the other species roost permanently. The old buildings in the study area provide suitable habitats for a significant number of insectivore bats. Indian Flying Fox (Pteropus gigantius) was the largest (mean head body length 23.33±1.86cm) and Least Pipistrelle (Pipistrellus tenuis) was the smallest (mean head body length 39.45±1.66 mm) species observed from the study area.Bangladesh J.

We present a mechanism that can explain the growth direction of the carbon nanotubes (CNT), based on the observation of the catalyst particle's shape, that is present along with the CNT. We claim the mechanism holds good for the tip growth as well as the base growth model for CNTs formation. The morphological studies performed using simple geometry show that for encapsulated catalyst, (i) the contact angle is less along the forward direction than that of backward direction, (ii) the growth direction of CNT is along the flow direction of the catalyst particle in the fluid state, (iii) the distance between the centre of two imaginary spheres (circles in 2D) drawn at the front and back of the catalyst particle, qualitatively predicts the difference in growth rate of the CNT and flow of the catalyst particle inside the CNT. In order to support the above claims, a generalized model is proposed, irrespective of the position of the catalyst.

Strauss's historical investigation of the use of exoteric writing in Farabi, Maimonides, Halevi, and Spinoza, is in fact his history of the philosophers' exoteric accommodations to the permanent difference in human natures, the difference between the many who require a categorical moral teaching and the few who are capable of ordering their own lives in the face of the hypothetical status of all moral commands. The men of the Enlightenment aspired to render the moral law superfluous for all by constructing a machinery of government powerful enough to compel all to live justly. Strauss critiques this aspiration by leading his reader to face the permanency of the difference between the few and the many. Strauss uses historical scholarship to force the reader to rethink the possibility of contemplation of the eternal or permanent, the possibility that the Enlightenment's historicist epigones have sought to foreclose.

The question to be explored is that of how far a Christian identity can be stretched and yet still remain “Christian” and who determines the limits and for what reasons. This question is explored in light of the kakure kirishitan (hidden Christians) studies in Japan. More precisely, the question is that of how the historically singular epistemology embodied in the “one-God” understandings of Christianity has played out in multiple readings of reality, a “many gods” epistemology, in Japan. This is an exploration of the “meaning of divine revelation of Christ” set within the context of ecclesia semper reformanda. I would claim that the “character of love” as defined by Ernst Troeltsch’s notion of the revelation of Christ (“In our earthly experiences the Divine Life is not One, but Many. But to apprehend the One in the Many constitutes the special character of love”), which is a distinct Christian faith paradigm, contrary to the popular paradigm in the academic and civic discourse of “one in many,” takes on the character of “the sounding of the heart.” Even when the historical identity of Christ is extensively eroded, the “sounding” speaks to people beyond the difference of the worlds with a language that is so intimate that it profoundly grasps the heart.
