Perfusion of onion root xylem vessels: a method and some evidence of control of the pH of the xylem sap
No full textWe describe a method for perfusing the xylem in the stele of excised onion roots with solutions of known composition under a pressure gradient. Tracer studies using [14C] polyethylene glycol 4000 and the fluorescent dye, Tinopal CBSX, indicated that perfusing solutions passed exclusively through the xylem vessels. The conductance of the xylem was small over the apical 100 mm of the root axis but increased markedly between 100 and 200 mm. Unbuffered perfusion solutions supplied in the range pH 3.7–7.8 emerged after passage through the xylem adjusted to pH 5.2–6.0, indicating the presence of mechanisms for absorbing or releasing protons. This adjustment continued over many hours with net proton fluxes apparently determined by the disparity between the pH of the perfusion solution and the usual xylem sap pH of about 5.5.

Mapping the Landscape: A Bibliometric Analysis of CALIBER 2022 Convention Publications
No full textThe present study examines the authorship patterns, collaboration levels, and various other parameters such as gender, author designation, institutional affiliation, and geographical distribution of the conference papers presented at CALIBER 2022 by employing an array of bibliographic analysis techniques. The analysis is based on a dataset consisting of 45 papers authored by 100 individuals and found that authors hailing from Uttar Pradesh emerged as the foremost contributors. The study also found that universities emerged as the most prolific contributors, responsible for the publication of 71.00 per cent of the articles within the designated time frame

The perfect three: ontology as trinity
No full textThe Ontological Argument fo r the existence of God is briefly examined with particular reference to its basic premise, the assumption of the perfection of God. Despite some problems with the idea, it is believed that perfection is a valid concept. The thrust of the article is that if a perfect God exists, such perfection requires at least the basic concepts of the doctrine of the Trinity . The author therefore believes th a t the idea of the Trinity is derivable in a rudimentary form without reference to either revelation or to the "vestigia" (the supposed reflection of the Trinity in the creation), but simply from the idea of perfection. Some authors, both medieval and modern are cited in support of the argument
Eastern Iran in the Achaemenid Period
No full textThe author deals with the archaeological evidence of the Achaemenid period in eastern Iran. This evidence is limited, rare and contradictory with regard to the historical importance of the eastern provinces of the Empire. The territorial extent of the Achaemenid Empire is ambiguous too and in this regard the cultural background of the different provinces, as well as relationships between center and periphery, were crucial factors affecting the visibility of the Achaemenid empire in its eastern-most regions. Similarly, the geographic definition of ‘eastern Iran’ requires clarification as well because, as a geomorphological unit. Thus at least four different aspects of interpretation should be considered when considering the evidence of the Achaemenid empire in the east:
1. the dynastic - identifiable by inscriptions, coins and seals
2. the ethnic - possibly detectable on both physical anthropological and cultural grounds
3. the political/imperial - recognizable both in macroscopic architectural and art historical remains and in the material traces of settlement patterns and economic investments, e.g. to secure the water supply
4. the chronological - interpretable in the differing horizons connected to the period of Achaemenid political-dynastic dominion in the area
The Zen-inflected Cosmological Imaginations of William Carlos Williams and Alan Watts
No full textThe effervescent cultural scene of the West Coast in the 1950s—particularly regarding movements such as the San Francisco Renaissance and the Beat Generation—was influenced by Eastern thought and religious practices. These were disseminated by figures such as the Japanese scholar D.T. Suzuki and the Bay Area-based and self-proclaimed “philosophical entertainer” Alan Watts. Along with Watts, another influential figure for the West Coast poets—having even served as mentor to Allen Ginsberg—was William Carlos Williams. This essay argues that, influenced by Zen Buddhist principles, both Williams and Watts propose a vision of the imagination as a cosmological force capable of merging the material and transcendental dimensions of reality. This essay suggests that Williams’s and Watts’s concepts and their understanding of Zen Buddhist ideas deeply affected the works of the West Coast poets and laid the foundations for their cross-cultural interests as well as their experimentation with poetics and spirituality
