On the digital forensic analysis of the Firefox browser via recovery of SQLite artifacts from unallocated space
A technique and supporting tool for the recovery of browsing activity (both stored and deleted) from current and recent versions of the Firefox web-browser is presented. The generality of the technique is discussed: It is applicable to any software that uses the popular SQLite embedded database engine such as the Apple Safari web-browser and many Android apps

Chemosensory Behavior and Development of African Male Elephants (Loxodonta Africana)
African elephants are a polygynous species that raise offspring in a matriarchal society. Males disperse, spend time in male groups, and search for mates when mature. Urinary chemical signals play an important role in detecting reproductively active females. African male elephants develop movement, social and chemosensory behaviors over four major life changes. The first goal of this study was to compare behavior among four classes of wild African male elephants in Addo Elephant National Park, South Africa. The second goal was to determine if adult captive African male elephants distinguish between urine from conspecific females in receptive and non-receptive estrous stages. Behaviorally, younger male elephants were more investigative, while older males exhibited more physical social interactions. The development of chemosensory behavior appeared to parallel general behavioral patterns in this polygynous species. Captive male elephants discerned between the two urine types, bolstering the pursuit to identify the estrous pheromone in African elephants
Less Is More: The Physiological Basis for Tapering in Endurance, Strength, and Power Athletes
Taper, or reduced-volume training, improves competition performance across a broad spectrum of exercise modes and populations. This article aims to highlight the physiological mechanisms, namely in skeletal muscle, by which taper improves performance and provide a practical literature-based rationale for implementing taper in varied athletic disciplines. Special attention will be paid to strength- and power-oriented athletes as taper is under-studied and often overlooked in these populations. Tapering can best be summarized by the adage “less is more” because maintained intensity and reduced volume prior to competition yields significant performance benefits
Growth states of catalytic reaction networks exhibiting energy metabolism
All cells derive nutrition by absorbing some chemical and energy resources
from the environment; these resources are used by the cells to reproduce the
chemicals within them, which in turn leads to an increase in their volume. In
this study, we introduce a protocell model exhibiting catalytic reaction
dynamics, energy metabolism, and cell growth. Results of extensive simulations
of this model show the existence of four phases with regard to the rates of
both the influx of resources and the cell growth. These phases include an
active phase with high influx and high growth rates, an inefficient phase with
high influx but low growth rates, a quasi-static phase with low influx and low
growth rates, and a death phase with negative growth rate. A mean field model
well explains the transition among these phases as bifurcations. The
statistical distribution of the active phase is characterized by a power law
and that of the inefficient phase is characterized by a nearly equilibrium
distribution. We also discuss the relevance of the results of this study to
distinct states in the existing cells.Comment: 21 pages, 5 figure
Feasibility Study of Establishing a Water Rights Banking/Brokering Service in Utah
Changes in water use patterns are an inevitable consequence of relentless social transformations taking place. Especially where waters have been fully appropriated, the needs of a dynamic society must be met through transfers in water ownership. Yet, there are a variety of factors that may operate as impediments to the shifting of water according to social preferences as expressed through water markets. As a mechanism for facilitating water transfers, exchagnes, or rentals, the concept of water banking and water brokering may be fruitful. This repot appraises the potential for initiating and operating such a service within the legal, institutional, and organizational framework prevailing in Utah. Questions addressed are: What are the special characteristics of water rights and water right owners that constitute important elements of the market arena? How would a banking and/or brokering service effectively deal with the mix of marketable water right equities ranging from the general corporate right (exercised in satisfying an unlimited variety of individual uses at the pleasure of the corporation, i.e. municipality, conservancy district, etc.); the individual proportion of share of a mutally owned right; to the individually owned water right? However would the water banking operation be coordinated with the State Engineer who must approve all changes in use? What are the organizational alternatives for establishing a water bank? Should such a service be sponsored and operated as a public or private activity? What are the legal considerations that must be addressed? Are there constitutional, statutory, or procedural consideratiosn taht seriously constrain the operation of a water banking/brokering service? Can such a service be made to complement present institutional structures and whatever forms of banking and brokering they may currently provide? What are the economic considerations in the creation of a water banking/brokering service? It is concluded that a water bank could be effective in facilitating cost-effective and resource efficeint matchups of buyers and sellers of water. There are no constitutional, statutory, or regulative elemetns in Utah water administration that would seriously hinder the operation of a water banking/brokering system. However, there are some institutional peculiarities and debt encumbrances that may limit the market potential of particular water right equities. The protection of third party interests to any water rights transaction is a central consideration in arranging water transfers, exchanges, or rentals. Therefore, the water bank must be staffed by individuals having technical understanding of the hydrologic and legal impacts and the economic externalities that accompany particular water use changes. An appraisal of existing Utah organizations capable of assuming a water banking/brokering service suggest the Office of the State Engineer (public) and the Utah Water Users Association (private) as the two most liekly candidates. It is recommended that the evaluation of these two organizations now be made in more detail with respect to suitability of the new banking/brokering service to basin mission, current operating policies and programs, organizational structure, and fiscal and budgetary framework. Decision to initiate the concept should probably begin with a limited level of service, adding more comprehensive and more professional elements as justified by oeprating experience
