Apple Fruit Growth and Quality Depend on the Position in Tree Canopy

Modern apple orchard systems should guarantee homogeneity of fruit internal and external qualities and fruit maturity parameters. However, when orchards reach productive age, a variation of these parameters takes place and mostly it is related to uneven light distribution within the tree canopy. The aim of the study was to evaluate the canopy position’s effect on fruit internal and external quality parameters. This is the first study where all the main fruit quality and maturation parameters were evaluated on the same trees and were related to the light conditions and photosynthetic parameters. Four fruit positions were tested: top of the apple tree, lower inside part of the canopy, and east and west sides of the apple tree. Fruit quality variability was significant for fruit size, blush, colour indices, total sugar content, dry matter concentration, accumulation of secondary metabolites and radical scavenging activity. Fruit position in the canopy did not affect flesh firmness and fruit maturity parameters such as the starch index, Streif index and respiration rate. At the Lithuanian geographical location (55°60’ N), significantly, the highest fruit quality was achieved at the top of the apple tree. The tendency was established that apple fruits from the west side of the canopy have better fruit quality than from the east side and it could be related to better light conditions at the west side of the tree. Inside the canopy, fruits were distinguished only by the higher accumulation of triterpenic compounds and higher content of malic acid. Light is a main factor of fruit quality variation, thus all orchard management practices, including narrow two-dimensional tree canopies and reflecting ground covers which improve light penetration through the tree canopy, should be applied.

Taking the Reins

The genesis of the present-day director-choreographer, starting with de Mille’s role as director-choreographer on Rodgers and Hammerstein’s ill-fated Allegro (1947), is explored. How she employed dance as a narrative and metaphorical device in support of the allegorical structure of the libretto, and how her artistic vision conflicted with her collaborators is investigated. De Mille’s directorial oeuvre is considered in the context of the male-dominated world of Broadway. Robbins’ ascendance as the most influential director-choreographer of twentieth-century musical theater is examined in a close analysis of his choreography for and direction of Pajama Game (1954 [co-directed with George Abbott, co-choreographer Bob Fosse]), Peter Pan (1954), Bells Are Ringing (1956 [in which he collaborated with Bob Fosse]), Gypsy (1959), and Fiddler on the Roof (1964). West Side Story (1957) will be discussed here as an anomaly in Robbins’ musical theater career. I argue that Robbins’ interest in movement innovation in relation to his choreography for the “Jets” in West Side Story (1957) differs from his previous musical theater works. In addition, I will examine Robbins’ West Side Story collaboration with co-choreographer Peter Gennaro.

Unique Lassoing Scene from the Mastaba of Akhmerutnisut at Giza (G 2184)

This article analyzes a unique scene from the Giza mastaba of Akhmerutnisut (G 2184), which shows a life-size depiction of the tomb owner holding a rope, ready to throw a lasso. The active participation of the tomb owner in a lassoing scene is unique in the iconographic program of Fifth Dynasty elite tombs. The location of this scene within the mastaba is also unparalleled: it is the first scene on the right (west side) encountered by visitors as they enter the mastaba. To understand this innovative decorative choice, this paper starts by discussing the iconography of lassoing in the Old Kingdom and its meaning in the elite tombs of the same period. The second part of this paper analyzes Akhmerutnisut’s lassoing scene with an analytical framework drawn from visual and material culture studies and focusing on the concepts of monumentality, identity and agency. This study provides a number of possible explanations—none of which are mutually exclusive—to understand why Akhmerutnisut had himself depicted as a monumental lassoer by the entrance of his funerary complex, highlighting the importance of visitor experience and participation in the design of the funerary complexes of the Old Kingdom elite.

Understanding of an Iceberg Breaking Off Event Based on Ice-Front Motion Analysis of Amery Ice Shelf, Antarctica

On 26 September 2019, a massive iceberg broke off the west side of the Amery Ice Shelf (AIS) in East Antarctica. Since 1973, the AIS calving front has steadily advanced at a rate of 1.0 km yr−1. However, the advancement rate of the central portion of the AIS increased dramatically during 2012–2015, which indicates a velocity increase prior to the calving event. Eight calving front locations from 1973 to 2018 were mapped to investigate the advancement rate of AIS over the entire observational period. Additionally, the propagation of rift A was observed unstable from 2012 to 2015. The westward propagation rate of rift A1 increased to 3.7 km yr−1 from 2015 to 2017, which was considerably faster than the other rifts near the AIS calving front. The increased advancement rate and the increasing propagation magnitude of at least one active rift appear to be precursors of this large calving event.

Images of Homelessness: The Home of the Needy Aged

Homelessness in 1880s New Zealand, as reported in the press, appears to be more intimate and less melodramatic than overseas examples. House fires, such as that of William Beals' eight-roomed house in Epsom, the destruction by fire of Mr Keogh's seven-roomed dwelling on the north-west side of Mount Pukekaroro, and the 1884 fire which broke out "on the grounds of St. Mary's Orphanage, Ponsonby" are examples. Chronic homelessness, when it appears, occurs via the reporting of institutional and architectural support structures. The paper will examine a specific example of an architecture for the homeless: the Home for the Needy Aged in Newtown, Wellington.

Harmful algal blooms and their impact on fish mortalities in Lampung Bay: an overview

The first disaster caused by harmful algal blooms in Lampung Bay was reported in 1991, where mass mortality of cultivated shrimp occurred in the brackish water ponds due to a Trichodesmium bloom. After this incident, the phenomenon reoccured in the following years continuously. Around nine species bloom makers in this bay are namely Pyrodinium sp., Noctiluca sp., Phaeocystis sp., Dinophysis sp., Trichodesmium sp., Ceratium sp., Prorocentrum sp., Pseudonitzhia sp., and Cochlodinium sp. The most frequent causative species, such as green Noctiluca and Trichodesmium, co-occurring during blooms and causing fish mortalities in the fish farming floating nets (KJA). Two species are known as the most potentially harmful species, namely Pyrodinium sp. and Cochlodinium sp. Cochlodinium blooms happened at the end of 2012, and since then, this species has continuously reappeared in the following years. The outbreak of Cochlodinium sp. still appeared in 2017 and 2018, but no fish-killing occurred. Phytoplankton bloom events occur at specific locations, mainly at fish farming floating nets on the west side of the bay, next to Hurun Cove. This paper discusses the occurrence of algal blooms in Lampung Bay and the triggering factors for increasing phytoplankton populations that cause harmful algal blooms.

Arduino-based night return mechanism for passive solar trackers

<p>Solar trackers are support platforms that keep photovoltaic panels facing the sun by following the sun from dusk to dawn. There exist active solar trackers that make use of motors and gears to orientate the photovoltaic panels towards the sun; and passive solar trackers that operate through the differential heating of the fluid in the tracking rack to follow the sun. Passive solar trackers suffer from the lack of a night return mechanism and a slow wake-up response in the mornings due to the limitations on the surface inclination angle of the rack. This paper seeks to address these issues by proposing an Arduino-based night return mechanism for passive solar trackers. An energy-saving heating element such as the ultra heating fabric manufactured by WireKinetics Co. is installed on the west-side canister of the tracker. Before dawn, the fabric is automatically heated and this will force the refrigerant in the west-side canister to vaporize and cool in the east- side canister, forcing the tracker to return and face eastward before sunrise. The night return mechanism is designed and simulated using Proteus profesional. Simulation results show that this system can significantly optimize the function of passive solar trackers.</p>

First person: West side (teaching) story

A white, midwestern teacher reflects on the lessons he learned from his Latinx students while teaching Romeo and Juliet on the Upper West Side of Manhattan in the 1990s. While Romeo and Juliet was an easier sell than he expected, the class had a different reaction to West Side Story.

Redesigning space layout by considering thermal comfort and prevention of COVID-19 transmission in campus building

Lecture building is one of the important facilities in supporting the success of the teaching and learning process. The lecture room should be thermally comfortable and has a low risk of disease transmission. In adapting to the Covid-19 pandemic, attention to prevent disease transmission is necessary to the safety of students and lecturers while staying on campus. This study aims to propose a new concept design related to the arrangement of indoor layouts that minimize the crowds and reducing indoor air temperatures due to exposure to solar radiation on the east-west side of the building. The research was conducted by observing human movement patterns and measuring indoor air temperature and surface façade temperature adjacent to the outside environment. The results obtained that the average indoor air temperature was in the range between 28.8 - 33.2 °C, with a surface temperature on the east-west side, reaching 39.1 °C. The new design proposed the concept of one-way access by separating vertical and horizontal circulation, additional corridors, and rearranging the layout of lecture rooms to distinguish in-out access to minimize contact physical contact between building users.
