Statistical analysis of Hydrographs of the Fuji Lakes (2nd Report)
No full textWe have studied the statistical property of the water-level of the Fuji lakes. In this paper, the author explained that the changes of the waterlevel had some continuity, that is, the changes were more continuous than the stochastic expectation, and the distribution of water-level between Motosu and Saiko has much correlation, but between Yamanaka and the others there is no correlation
STATISTICAL ADJUSTMENT OF HYDROGRAPH OF THE FUJI LAKES
No full textSome of the five lakes around Mt. Fuji, it is said, are connected with other. The author made scatter diagrams, control charts and time series diagrams by means of the rate of amplitude with statistical method, and proved that the western three lakes and the other two make respective groups and between these two groups there is no connection but there is much correlation among the western three but there are few between the easten two. These results coincide with the traditional legends
<i>Journey to See Fuji</i> (1567) by Satomura Jōha: About the Author, Circumstances of Creation, and Main Features of the Diary
No full textAt a time when many provincial daimyō were at war with their neighbors, and Oda Nobunaga was gradually becoming a central figure in the political arena, the renga poet Satomura Jōha and his disciples made a journey to Suruga province to see Mt. Fuji. Jōha described this journey in his travel diary, Journey to See Fuji. The diary clearly shows both the features of medieval travel diaries, such as the inclusion of renga and some waka, the strong influence of Ise Monogatari, references to Genji Monogatari and the diaries of Jōha’s predecessors, other renga poets. Journey to See Fuji also bears the characteristics of early modern travel diaries: the absence of a sense of forcedness and hardness of the journey (instead, Jōha is enjoying his travel), a detailed listing of the names of people met on the way, realistic depiction of places he visited, and descriptions of military hostilities.It is curious that, despite stating seeing Mt. Fuji as the main reason for his journey, Jōha writes about it very little. This diary is interesting not only for its literary and poetic part but also as a historical source from which it is possible to reconstruct the network of relationships between famous figures of the sixteenth century
Characteristics of salt inclusions in polar ice from Dome Fuji, East Antarctica
No full textWe studied the depth profile of the chemical properties, number concentration and average diameter of micro-inclusions in Antarctic ice from Dome Fuji. Analysis of the data indicated that the distribution of inclusions was not significantly modified during ice sheet flow, although a main constituent Na2SO4 center dot 10H(2)O changed into another solid phase in the deep ice. In the chemical form, sodium sulfate and magnesium sulfate were dominant in the interglacial and early-glacial ice, but were not detected in the glacial-maximum ice. Instead, the sulfate in the glacial-maximum ice was mainly in the form of calcium sulfate. This is strong support for the hypothesis that the neutralization regime of acid aerosols in the atmosphere and snowpack dramatically changed from chemical reaction with sea salt to that with dust during glacial maxima

Dairy Farming System on the West Slope Area of Mt. Fuji with Reference to Pasture Utilization
No full textAt the 15th International Grassland Congress held in 1985, the author presented a paper on the production and utilization of pasture and forage crops and land development programs currently in effect on the west slope of Mt. Fuji. Import of large amounts of concentrate and roughages from foreign countries was pointed out as a major problem. In the present study, farming was surveyed and analyzed to determine how dairy farming should best be conducted in the future. Particular attention is directed to pasture productivity and feed self-supply expressed in terms of UTDN for the conduct of farm business
Metamorphism of stratified firn at Dome Fuji, Antarctica : A mechanism for local insolation modulation of gas transport conditions during bubble close off
No full textThe evolution of the structure of a 112.59-m-long firn core recovered at Dome Fuji, East Antarctica, was investigated in order to improve understanding of firn densification and bubble formation processes, which are important for interpreting local insolation proxies used for astronomical dating of deep ice cores. Using selected samples, we measured physical properties including (i) the relative dielectric permittivities in both the vertical and horizontal planes, (ii) the bulk density at a resolution of millimeters, (iii) the three-dimensional geometric structure of pore space, and (iv) crystal orientation fabrics. We found that the firn at Dome Fuji contains horizontal strata with thicknesses of several centimeters. Near the surface of the ice sheet, these strata are characterized by contrasting bulk density. Earlier field studies suggest that summer insolation causes densification of surface firn. Down to ～30 m, density maxima exhibited a clear positive correlation with the strength of structural anisotropy and c-axis clustering around the vertical. In contrast, the correlation is negative in deeper firn, confirming previous findings that initially less dense firn became denser than initially dense firn. In addition, numerous examples of textures indicating that deformation preferentially occurred in weaker layers were found. Moreover, the initially dense firn layers were more permeable for air near the bottom of firn. We propose a model linking firn properties with conditions for the gas transport processes near the bottom of firn. The model explains how stronger insolation can lead to bulk ice with a lower O2/N2 ratio and smaller total gas content
Shelf-life estimation of 'Fuji' apples: Sensory characteristics and consumer acceptability
No full textApple texture can deteriorate during cold storage, resulting in softness and mealiness. The purpose of this work was to estimate shelf-life and to study the behavior of 'Fuji' apples kept at 20°C in a normal atmosphere until consumption following 7 months refrigerated storage (1°C) in a controlled atmosphere (2% O2, 2% CO2). Survival analysis methodology was used to estimate shelf-life. Its key concept is to focus the shelf-life hazard on the consumer rejecting the product rather than on the product deteriorating. The shelf-life estimated of 'Fuji' apples was 23 days with a 50% rejection probability and 17 days with a 25% rejection probability. Consumer acceptability and descriptive sensory analyses for storage periods of up to 28 days at 20°C indicated that the greatest quality loss was associated with increased mealiness, ripe taste and alcoholic taste and odor. Texture instrumental compression measures reflected the loss of rigidity of the apple tissue. The Thiault index and acceptability test results showed that the quality of the apples recently removed from cold storage was barely acceptable.The authors are indebted to the Comisiòn Interministerial de Ciencia y Tecnologia for financial support (Project AGL 2003-09208-C03-02) and to the Ministerio de Educaciòn y Ciencia (Spain) for the grant awarded to author P.

Effectiveness of Small Onshore Seawall in Reducing Forces Induced by Tsunami Bore: Large Scale Experimental Study
No full textTsunami force and pressure distributions on a rigid
wall fronted by a small seawall were determined experimentally
in a large-scale wave flume. Six different
seawall heights were examined, two of which were exposed
to a range of solitary wave heights. The same
experiment was done without a seawall for comparison.
The measured wave profile contained incident
offshore, incident broken, reflected broken, and transmitted
wave heights measured using wire resistance
and ultrasonic wave gauges. Small individual seawalls
increased reflection of the incoming broken bore front
and reduced force on the rigid landward wall. These
findings agree well with published field reconnaissance
on small seawalls in Thailand that showed a correlation
between seawalls and reduced damage on landward
structures.This is the publisher’s final pdf. The published article is copyrighted by the author(s) and published by Fuji Technology Press.

Dicarboxylic acids, oxocarboxylic acids and alpha-dicarbonyls in atmospheric aerosols from Mt. Fuji, Japan: Implication for primary emission versus secondary formation
No full textAerosol samples were collected at the summit of Mt. Fuji in July-August 2009 and analyzed for diacids and related compounds together with major ions to decipher the sources and formation process of organic aerosols in the free troposphere. Molecular distributions of diacids showed the predominance of oxalic acid (C-2) followed by succinic (C-4) and malonic (C-3) acids. The average concentration of total diacids is ten times higher in whole-day samples than night-only samples due to the uplift of planetary boundary layer in daytime, suggesting the day-time formation of diacids in the uplifted ground-level air mass along the mountain slope. A strong correlation is found between C-4 and levoglucosan in whole-day and nighttime samples. Liquid water content (LWC) shows strong correlations in nighttime with anthropogenic and biogenic secondary organic aerosol (SOA) tracers (e.g., adipic (0.90, p < 0.05) and phthalic acids (0.93, p < 0.05) and 3-methyl 2,3,4-trihydroxy-1-butene (0.95, p < 0.05), suggesting that aqueous-phase chemistry is important for the formation of water-soluble organic aerosols in the free troposphere. In whole-day samples, LWC is strongly correlated with organic carbon (r = 0.97, p < 0.05), and isoprene-SOA tracers such as methylthreitol (0.96, p < 0.05), methylerythritol (0.97, p < 0.05), 2-methylglyceric acid (0.94, p < 0.05) and glycolic acid (0.98, p < 0.05), suggesting that daytime SOAs are mainly from the oxidation of isoprene emitted from the regional forests on the foothill of Mt. Fuji. A strong correlation between LWC and glycolic acid further suggests that isoprene is the main precursor for the production of oxalic acid via glycolic acid as intermediate. This study supports the heterogeneous formation of diacids in the free troposphere
