    Description: "We’re going to build a wall.” Borders have been drawn since the beginning of time, but in recent years artificial barriers have become increasingly significant to the political conversation across the world. Donald Trump was elected President of the United States while promising to build a wall on the Mexico border, and in Europe, the international movements of migrants and refugees have sparked fierce discussion about whether and how countries should restrict access to their territory by erecting physical barriers. Virtual walls are also built and crushed at increasing speed. In the post-9/11 era there is a greater danger from so-called "transnational non-state actors”, and computer hacking and cyberterrorism threaten to overwhelm our technological barriers. In this timely and original book, Said Saddiki scrutinises the physical and virtual walls located in four continents, including Israel, India, the southern EU border, Morocco, and the proposed border wall between Mexico and the US. Saddiki’s detailed analysis explores the tensions between the rise of globalisation, which some have argued will lead to a "borderless world” and "the end of the nation-state”, and the rapid development in recent decades of border control systems. Saddiki examines both regular and irregular cross-border activities, including the flow of people, goods, ideas, drugs, weapons, capital, and information, and explores the disparities that are reflected by barriers to such activities. He considers the consequences of the construction of physical and virtual walls, including their impact on international relations and the rise of the multi-billion dollar security market. World of Walls: The Structure, Roles and Effectiveness of Separation Barriers is important reading for all those interested in the topics of immigration, border security, international relations, and policy.

    Description: Mowafa Said Househ’s family fled Palestine in 1948 and arrived in Canada in the 1970s. He spent his childhood in Edmonton, Alberta, where he grew up as a visible minority and a Muslim whose family had a deeply fractured history. In the year 2000, when Mowafa visited his family’s homeland of Palestine at the beginning of the Second Intifada, he witnessed the effects of prolonged conflict and occupation. It was those observations and that experience that inspired him not only to tell his story but to realize many of the intergenerational and colonial traumas that he shares with the Indigenous people of Turtle Island. His moving memoir depicts the lives of those who live on occupied land and the struggles that define them.

    Description: A mesophilic toluene-degrading consortium (TDC) and an ethylbenzene-degrading consortium (EDC) were established under sulfate-reducing conditions. These consortia were first characterized by denaturing gradient gel electrophoresis (DGGE) fingerprinting of PCR-amplified 16S rRNA gene fragments, followed by sequencing. The sequences of the major bands (T-1 and E-2) belonging to TDC and EDC, respectively, were affiliated with the family Desulfobacteriaceae. Another major band from EDC (E-1) was related to an uncultured non-sulfate-reducing soil bacterium. Oligonucleotide probes specific for the 16S rRNAs of target organisms corresponding to T-1, E-1, and E-2 were designed, and hybridization conditions were optimized for two analytical formats, membrane and DNA microarray hybridization. Both formats were used to characterize the TDC and EDC, and the results of both were consistent with DGGE analysis. In order to assess the utility of the microarray format for analysis of environmental samples, oil-contaminated sediments from the coast of Kuwait were analyzed. The DNA microarray successfully detected bacterial nucleic acids from these samples, but probes targeting specific groups of sulfate-reducing bacteria did not give positive signals. The results of this study demonstrate the limitations and the potential utility of DNA microarrays for microbial community analysis.

    Description: Oligonucleotide microarrays were used to profile directly extracted rRNA from environmental microbial populations without PCR amplification. In our initial inspection of two distinct estuarine study sites, the hybridization patterns were reproducible and varied between estuarine sediments of differing salinities. The determination of a thermal dissociation curve (i.e., melting profile) for each probe-target duplex provided information on hybridization specificity, which is essential for confirming adequate discrimination between target and nontarget sequences.

    Description: The discrimination between perfect-match and single-base-pair-mismatched nucleic acid duplexes was investigated by using oligonucleotide DNA microarrays and nonequilibrium dissociation rates (melting profiles). DNA and RNA versions of two synthetic targets corresponding to the 16S rRNA sequences of Staphylococcus epidermidis (38 nucleotides) and Nitrosomonas eutropha (39 nucleotides) were hybridized to perfect-match probes (18-mer and 19-mer) and to a set of probes having all possible single-base-pair mismatches. The melting profiles of all probe-target duplexes were determined in parallel by using an imposed temperature step gradient. We derived an optimum wash temperature for each probe and target by using a simple formula to calculate a discrimination index for each temperature of the step gradient. This optimum corresponded to the output of an independent analysis using a customized neural network program. These results together provide an experimental and analytical framework for optimizing mismatch discrimination among all probes on a DNA microarray.

    Description: The effects of single-base-pair near-terminal and terminal mismatches on the dissociation temperature (T(d)) and signal intensity of short DNA duplexes were determined by using oligonucleotide microarrays and neural network (NN) analyses. Two perfect-match probes and 29 probes having a single-base-pair mismatch at positions 1 to 5 from the 5' terminus of the probe were designed to target one of two short sequences representing 16S rRNA. Nonequilibrium dissociation rates (i.e., melting profiles) of all probe-target duplexes were determined simultaneously. Analysis of variance revealed that position of the mismatch, type of mismatch, and formamide concentration significantly affected the T(d) and signal intensity. Increasing the concentration of formamide in the washing buffer decreased the T(d) and signal intensity, and it decreased the variability of the signal. Although T(d)s of probe-target duplexes with mismatches in the first or second position were not significantly different from one another, duplexes with mismatches in the third to fifth positions had significantly lower T(d)s than those with mismatches in the first or second position. The trained NNs predicted the T(d) with high accuracies (R(2) = 0.93). However, the NNs predicted the signal intensity only moderately accurately (R(2) = 0.67), presumably due to increased noise in the signal intensity at low formamide concentrations. Sensitivity analysis revealed that the concentration of formamide explained most (75%) of the variability in T(d)s, followed by position of the mismatch (19%) and type of mismatch (6%). The results suggest that position of the mismatch at or near the 5' terminus plays a greater role in determining the T(d) and signal intensity of duplexes than the type of mismatch.
