The paper investigates the effectiveness of the privacy mode feature in three widely used Web browsers, and outlines how to investigate when these browsers have been used to perform a criminal or illegal act. It performs an identical test on a privacy mode session for each of the three Web browsers and investigates whether traces are left behind. The analysis is done in three phases. First, common places where history and cache records are usually stored are examined. Then, other locations on the local machine are examined using special forensic tools. Also, the physical memory (RAM) is captured and examined for traces. Index Terms-Private browsing, artifacts left by private browsing, incognito, in-private and Firefox private browsing.

Database technologies are a core component of computing technology curricula. Their importance will only continue to expand as more and more data are retained in database systems. An effective database system is predicated on a good data model. Database design is the conceptualization of an underlying data model that progresses from identifying user requirements to graphically depicting those requirements and finally mapping the graphical models to a set of tables implemented in a physical database system. The abstract nature of much of database design makes it challenging to teach. This paper presents a set of software animations designed to support the teaching of database design concepts. Topic areas covered include mapping problem descriptions to Entity Relationship (ER) diagrams, mapping ER diagrams to tables, normalization and denormalization and comparison of various ER notation sets. The animations are fairly intuitive to use and are independent of any specific database text or product. They are intended to provide supplemental instructional support and also provide students with additional learning opportunities.

O presente estudo foi conduzido no período de julho a dezembro de 1998, em galpão coberto, no DSER/CCA/UFPB, município de Areia, PB, com o objetivo de se avaliar o efeito dos níveis de água disponível no solo (AD) (20, 40, 60 e 80%) sobre a emissão/abscisão de estruturas reprodutivas do algodoeiro herbáceo, cv. CNPA 7H; utilizou-se delineamento experimental inteiramente casualizado, com quatro tratamentos e três repetições, em três épocas de amostragem. O crescimento vegetativo e o reprodutivo, aumentaram com os níveis de AD no solo, sendo a menor média de altura de plantas (34,5 cm), área foliar (633,05 cm²), acumulação de fitomassa da parte aérea (9,04 g), botões florais (4,67), flores (3,50), maçãs (2,33) e capulhos (1,33) por planta, observada no tratamento com o nível de 20% da AD e a maior, 74,33 cm, 2.634,81cm², 24,86 g, 9,67, 7,0, 6,0 e 4,3 por planta, respectivamente, no tratamento com o nível de 60% da AD. Apesar do estresse hídrico ter afetado (p<0,05) quantitativamente o aumento da emissão e abscisão de estruturas reprodutivas do algodoeiro, existe uma inter-dependência entre essas estruturas, independente do nível de estresse hídrico a que foi submetido; assim, o aumento ou redução do número de botões florais retidos culmina com o de flores, maçãs e capulhos de forma sucessiva, mantendo uma proporcionalidade padrão.

Traditional Database Security has focused primarily on creating user accounts and managing user privileges to database objects. The wide spread use of databases over the web, heterogeneous client-server architectures, application servers, and networks creates an urgent need to widen this focus. This paper will provide an overview of the new and old database security challenges.Section one provides an overview of the Database Security concerns. It emphasizes Database Applications as the greatest concern and describes the SQL Slammer Worm, an example of not patching the Database Management System (DBMS)The second section explains in detail three Database topics: SQL injection [1], Multilevel Security [2] and Data Warehouse/Data Mining/Statistical security. The reason for focusing on these topics is because they are new Database Security issues (at least not taught in traditional database courses) and they are not topics that student will learn in any other course.
