History of biological warfare and bioterrorism.

Bioterrorism literally means using microorganisms or infected samples to cause terror and panic in populations. Bioterrorism had already started 14 centuries before Christ, when the Hittites sent infected rams to their enemies. However, apart from some rare well-documented events, it is often very difficult for historians and microbiologists to differentiate natural epidemics from alleged biological attacks, because: (i) little information is available for times before the advent of modern microbiology; (ii) truth may be manipulated for political reasons, especially for a hot topic such as a biological attack; and (iii) the passage of time may also have distorted the reality of the past. Nevertheless, we have tried to provide to clinical microbiologists an overview of some likely biological warfare that occurred before the 18th century and that included the intentional spread of epidemic diseases such as tularaemia, plague, malaria, smallpox, yellow fever, and leprosy. We also summarize the main events that occurred during the modern microbiology era, from World War I to the recent 'anthrax letters' that followed the World Trade Center attack of September 2001. Again, the political polemic surrounding the use of infectious agents as a weapon may distort the truth. This is nicely exemplified by the Sverdlovsk accident, which was initially attributed by the authorities to a natural foodborne outbreak, and was officially recognized as having a military cause only 13 years later.

Evaluation of Machine Learning Classifiers for Mobile Network Intrusion Detection Systems

Mobile malwares are increasing with the growing number of Mobile users. Mobile malwares can perform several operations which lead to cybersecurity threats such as, stealing financial or personal information, installing malicious applications, sending premium SMS, creating backdoors, keylogging and crypto-ransomware attacks. Knowing the fact that there are many illegitimate Applications available on the App stores, most of the mobile users remain careless about the security of their Mobile devices and become the potential victim of these threats. Previous studies have shown that not every antivirus is capable of detecting all the threats; due to the fact that Mobile malwares use advance techniques to avoid detection. A Network-based IDS at the operator side will bring an extra layer of security to the subscribers and can detect many advanced threats by analyzing their traffic patterns. Machine Learning(ML) will provide the ability to these systems to detect unknown threats for which signatures are not yet known. This research is focused on the evaluation of Machine Learning classifiers in Network-based Intrusion detection systems for Mobile Networks. In this study, different techniques of Network-based intrusion detection with their advantages, disadvantages and state of the art in Hybrid solutions are discussed. Finally, a ML based NIDS is proposed which will work as a subsystem, to Network-based IDS deployed by Mobile Operators, that can help in detecting unknown threats and reducing false positives. In this research, several ML classifiers were implemented and evaluated. This study is focused on Android-based malwares, as Android is the most popular OS among users, hence most targeted by cyber criminals. Supervised ML algorithms based classifiers were built using the dataset which contained the labeled instances of relevant features. These features were extracted from the traffic generated by samples of several malware families and benign applications. These classifiers were able to detect malicious traffic patterns with the TPR upto 99.6% during Cross-validation test. Also, several experiments were conducted to detect unknown malware traffic and to detect false positives. These classifiers were able to detect unknown threats with the Accuracy of 97.5%. These classifiers could be integrated with current NIDS', which use signatures, statistical or knowledge-based techniques to detect malicious traffic. Technique to integrate the output from ML classifier with traditional NIDS is discussed and proposed for future work.

The influence of investigator disturbance on aggressive behaviour and breeding success of ring-billed gulls (Larus delawarensis) /

Increased losses of eggs and chicks resulting from human intrusion (investigator or other) into seabird colonies has been well documented. In 1990/91, I studied the effects of investigator disturbance on aggressive behaviour and breeding success of individual pairs of ring-billed gulls nesting at two colonies near Port Colborne, Ontario. The insular colony was on an artificial breakwall, associated with the Welland Ship Canal, approximately 1 km off the north shore of Lake Erie. The mainland colony was adjacent to the canal approximately 1 km east of the breakwall. The frequencies of adult threat and assault behaviours, chick movement and adult attacks on chicks were recorded by continuous scan sampling 30 min prior to, 30 min during and 60 (2 X 30) min after investigator disturbance. The frequency of threat and assault behaviours increased during the period of investigator activity in the colony while the duration of wingpulls and beakpulls decreased. Significantly more chicks ran ("runners") from their natal territories during disturbances and "runners" were more frequently attacked than "territorial" chicks. No chicks were fatally attacked during disturbance and "runners" returned to their natal territories quickly after disturbance. Breeding success was determined for pairs nesting in study plots subjected to two levels of disturbance (normal and moderate). The disturbance level of each plot differed in visitation frequency and activities performed on each visit. Investigator disturbance had no effect on the hatching success or fledging success (taken as 21 days of age) of ring-billed gull study pairs at either colony.

Elucidation of a mechanism of cell lysis by chorhexidine : a biophysical approach

Chlorhexidine is an effective antiseptic used widely in disinfecting products (hand soap), oral products (mouthwash), and is known to have potential applications in the textile industry. Chlorhexidine has been studied extensively through a biological and biochemical lens, showing evidence that it attacks the semipermeable membrane in bacterial cells. Although extremely lethal to bacterial cells, the present understanding of the exact mode of action of chlorhexidine is incomplete. A biophysical approach has been taken to investigate the potential location of chlorhexidine in the lipid bilayer. Deuterium nuclear magnetic resonance was used to characterize the molecular arrangement of mixed phospholipid/drug formulations. Powder spectra were analyzed using the de-Pake-ing technique, a method capable of extracting both the orientation distribution and the anisotropy distribution functions simultaneously. The results from samples of protonated phospholipids mixed with deuterium-labelled chlorhexidine are compared to those from samples of deuterated phospholipids and protonated chlorhexidine to determine its location in the lipid bilayer. A series of neutron scattering experiments were also conducted to study the biophysical interaction of chlorhexidine with a model phospholipid membrane of DMPC, a common saturated lipid found in bacterial cell membranes. The results found the hexamethylene linker to be located at the depth of the glycerol/phosphate region of the lipid bilayer. As drug concentration was increased in samples, a dramatic decrease in bilayer thickness was observed. Differential scanning calorimetry experiments have revealed a depression of the DMPC bilayer gel-to-lamellar phase transition temperature with an increasing drug concentration. The enthalpy of the transition remained the same for all drug concentrations, indicating a strictly drug/headgroup interaction, thus supporting the proposed location of chlorhexidine. In combination, these results lead to the hypothesis that the drug is folded approximately in half on its hexamethylene linker, with the hydrophobic linker at the depth of the glycerol/phosphate region of the lipid bilayer and the hydrophilic chlorophenyl groups located at the lipid headgroup. This arrangement seems to suggest that the drug molecule acts as a wedge to disrupt the bilayer. In vivo, this should make the cell membrane leaky, which is in agreement with a wide range of bacteriological observations.

Clendenan-Thompson family fonds

Daniel Clendenan (1793-1866) was the son of Abraham Clendenan, a private in Butler’s Rangers. He was married to Susan[na] [Albrecht ] Albright, daughter of Amos Albright. Daniel and Susan[na] had twelve children and belonged to the Disciple Church. In 1826 Daniel Clendenan purchased Part lot 14, Concession 6, Louth Township from Robert Roberts Loring. On this property he built a home and conducted the business of blacksmithing and along with William Jones operated a lumber mill. Volume 1 and the first part of Volume 2 are Daniel Clendenan’s account books. Daniel and his wife Susan are buried in the Vineland Mennonite cemetery. Daniel and Susan[na]’s youngest daughter, Sarah, married widower Andrew Thompson (1825-1901), son of Charles and grandson of Solomon. Andrew Thompson had settled in the Wainfleet area in 1854 and had owned a mill in Wellandport. Daniel Clendenan, in ill health, passed ownership of Lot 14, Concession 6, Louth Township to his son-in-law Andrew Thompson. Robert Roberts Loring, the original owner of lot 14, concession 6 in Louth was born in September of 1789 in England. He joined the 49th Regiment of Foot as an ensign in December of 1804 and arrived in Quebec the following July. He served with Isaac Brock and Roger Sheaffe. In 1806 he was promoted to lieutenant. Loring was hired by Lieutenant General Gordon Drummond and accompanied him to Ireland in 1811, but the outbreak of war in the States in 1812 drew Loring back to Canada. On June 26, 1812 Loring became a captain in the 104th Regiment of Foot. On October 29 of the same year, he was appointed aide-de-camp to Sheaffe who was the administrator of Upper Canada. During the American attack on York in April 1813, Loring suffered an injury to his right arm from which he never recovered. In December of 1813, Drummond assumed command of the forces in Upper Canada and he appointed Loring as his aide-de-camp, later civil secretary and eventually his personal secretary. Loring was with Drummond in 1813 at the capture of Fort Niagara (near Youngstown), N.Y. He was also with Drummond in the attacks on Fort Niagara, settlements along the American side of the Niagara River, and then York and Kingston. In July of 1814 he was promoted to brevet major, however he was captured at the Battle of Lundy’s Lane and he spent the remainder of the conflict in Cheshire, Massachusetts. One of his fellow captives was William Hamilton Merritt. Loring remained in the army and had numerous military posts in Canada and England. He retired in 1839 and lived the last of his years in Toronto. He died on April 1, 1848.

Percy Carruthers Band fonds, 1857-2005, n.d. (non-inclusive)

Percy Carruthers Band was born on November 27, 1892 in Toronto, Ontario to Charles Walter Band, a grain merchant and Jessie Camp Shaw Band. He graduated from Upper Canada College and became a broker. He worked at the Dominion Bank and then at Maple Leaf Milling Company. He was stationed at Port Colborne for a while. Before leaving for the front, he was with Bankers Bond Company of Toronto and is also listed as working with the firm of Bailey, Wood and Cross. Lieutenant Band received a Certificate of Military Qualifications on Dec. 24th, 1914. He received his Certificate of Military Instruction on Nov. 30, 1915. He received these certificates while with the 48th Regiment (Highlanders). He enlisted in 1914 and went overseas in August of 1915 as an officer in the 35th Battalion. By August 26, 1915, he is listed as being with the 23rd Reserve Battalion. A year later, in August of 1916 Lieutenant Band arrived in France and was posted to the 2nd Battalion – “The Second Iron”. In 1916, Band was the victim of shell shock received during a charge. He was wounded in April of 1917 at Vimy Ridge yet he remained on duty. At this time he received a gunshot wound to his right jaw. He earned a promotion to Captain on September 16th, 1917. He was wounded again in November of 1917 at Passchendaele where he suffered a gunshot wound to the ear. For his courage and determination Percy Band received the Military Cross on February 18, 1918. He led his company under difficult circumstances even though he was wounded. He was awarded a bar to the Military Cross for gallantry during a successful attack on two villages on December 2nd, 1918. During this attack he led his company against enemy machine guns. It is said that he displayed exceptional leadership qualities and skill during this time. On the 30th of August in 1918, he made a daring reconnaissance to the front under heavy fire in an attack on Upton Wood. He was also commended on his gallantry during attacks on Cagnicourt and the Canal du Nord in September of 1918. He was awarded the second bar to the Military Cross on February 1, 1919. The award of the Croix de Guerre was conferred on Captain Percy Carruthers Band by the President of the French Republic on December 15th, 1918 for distinguished service rendered during the course of the campaign. His general demobilization took place on April 25, 1919. Percy Band married Margaret Julia Woodruff on November 25, 1919, and they had three children: Charles Woodruff Band (1921), Margaret Elizabeth Band (1924) and Robert DeVeaux Woodruff Band (1927). After the war, Mr. Band was a manager at Geo. Weston Bread and Cakes Limited, St. Catharines. Percy Band was also an avid collector. His collections included antique toys and art. He died suddenly on May 19, 1961. The Toronto Telegram published this about him: “Captain Percy Carruthers Band, M.C. with two Bars, Croix de Guerre with Palm – was an officer whose buoyant spirit and gallantry mirrored the vibrant soul of the Battalion. Blythe of heart, yet endowed with a fine sense of responsibility, he gave inspired leadership of No. 3 Company.”

The Effects of Periodic Quotas Limiting the Stock of Imports of Durables

Analyses of trade quotas typically assume that the quota restricts the flow of some nondurable good. Many real-world quotas, however, restrict the stock of durable imports. We consider the cases where (1) anyone is free to export against such quotas and where (2) only those allocated portions of the total quota are free to export against such quotas. Recent econometric investigations of such quotas have focused on the price of the durable as an indicator of tightness induced by the quota. We show why this is an inappropriate indicator and suggest alternatives.

The Uneasy History of Lotteries

While the Present Popularity of Lotteries and the Ferocious Attacks They Are the Object of Would Induce One to Think They Are a Novelty, Lotteries Already Existed At the Dawn of History. in This Paper, We Will Give a Brief Historical Survey of Games of Chance, with Special Emphasis on Lotteries. This Survey Serves As a Background for Forthcoming Studies Where We Examine Why They Were Frequently Popular And, At the Same Time, the Object of the Scorn of a Number of Would-Be Reformers.

El extranjero y el derecho a la justicia en Canadá tras el 11 de septiembre

After the events of September 11, the fear of terrorism led to the adoption of new anti-terrorist measures (elimination of appeals available to foreigners, reduction of legal aid, increased powers of detention, easier use of security certificates…). But in Canadian Charter of Rigths and Freedoms only the right to vote and be elected, the right to enter and remain in the country and the minority language educational rights specifically protect citizens. The protection of Canadian citizens cannot be based on the denial of foreigner´s rights. The same rights are at stake: The violation of a foreigners´s rights is a violation of citizen´s rights.

Le processus d'adhésion à l'Union Européenne est-il en mesure de contribuer davantage que la Convention européenne à la protection des droits de l'homme en Turquie?

La Turquie va-t-elle adhérer à l'Union européenne? Sa candidature a toujours été sujette à critiques: droits de l'homme non respectés, restrictions des droits et libertés, notamment de la liberté d'expression, de religion et des droits politiques. Les dossiers sensibles comme le problème kurde et la question chypriote sont à l'origine des multiples plaintes contre l'État turc devant la Cour européenne des droits de l'homme. Dotée des caractéristiques essentielles d'un État moderne et laïque, le pays dispose de structures formellement démocratiques, mais sa démocratie se révèle fragile: ses politiques tant internes qu'externes sont décidées par un Conseil national de sécurité composé pour l'essentiel de militaires. En outre, l'armée qui a pris le pouvoir à maintes reprises a donné au régime une dimension autoritaire. Cela non seulement en vertu des principes fondateurs de la République (tradition centralisatrice de l'État turc), mais aussi de la priorité que l'institution militaire accorde à la sécurité, à l'unité et à l'identité nationales. En effet, les mesures d'exception (état d'urgence, cours de sûreté de l'État, loi anti-terroriste) ont contribué aux violations des droits de l'homme, d'où l'opposition entre le droit conventionnel et le droit national. De plus, le système judiciaire et administratif instauré par les militaires en 1982 n'est pas conçu dans l'intérêt des justiciables. Certes, l'accès à la modernité n'a pu se faire que sous la contrainte et le contrôle de l'armée, mais le régime en Turquie peut-il continuer à s'appuyer sur les«piliers de l'ordre» que sont l'armée, la police et la justice ? L’État semble cependant se réorganiser progressivement pour permettre au pouvoir politique d'assurer un contrôleur les forces de sécurité et pour donner une meilleure indépendance à la justice. Le processus mis en route et les critères imposés pour l'adhésion à l'UE devraient contribuer à mettre en œuvre les réformes institutionnelles capables d'harmoniser la démocratie à l'État de droit, à l'image des pays européens. En effet, les changements récents sont liés à l'agenda européen. Le gouvernement turc semble être déterminé et ambitieux dans sa vocation européenne. Les progrès réalisés pour intégrer l'UE lui sont un moteur de propulsion devant servir au pays et à sa population.

L’apolipoprotéine A-I interagit avec l’adhésine impliquée dans l’adhérence diffuse (AIDA-I) d’Escherichia coli : rôle lors du processus d’adhésion et d’invasion

L’adhésine impliquée dans l’adhérence diffuse (AIDA-I) est une adhésine bactérienne présente chez certaines souches d’Escherichia coli qui, associée aux toxines Stx2e ou STb, contribue à l’apparition de la maladie de l’œdème ou de la diarrhée post-sevrage chez les porcelets. AIDA-I est un autotransporteur qui confère des capacités d’autoaggrégation, de formation de biofilms et d’adhésion. L’objectif principal du projet de recherche consistait en la recherche de récepteur(s) potentiel(s) d’AIDA-I. Les bactéries pathogènes adhèrent aux cellules-cibles soit en liant directement des molécules à la surface cellulaire ou en utilisant des molécules intermédiaires qui permettent de diminuer la distance séparant la bactérie de la cellule-cible. Puisque le sérum est un fluide qui contient de nombreuses molécules, celui-ci a été utilisé comme matériel de départ pour l’isolement de récepteur(s) potentiels. Nous avons isolé un récepteur potentiel à partir du sérum porcin : l’apolipoprotéine A-I. L’interaction entre l’apolipoprotéine A-I et AIDA-I a été confirmée par ELISA et microscopie à fluorescence. La capacité à envahir les cellules épithéliales offre aux pathogènes la possibilité d’établir une niche intracellulaire qui les protègent contre les attaques du milieu extérieur. La présente étude a démontré que la présence d’AIDA-I en tant que seul facteur de virulence chez une souche de laboratoire permet de conférer la capacité d’envahir les cellules sans promouvoir la survie intracellulaire. L’étude de la souche sauvage 2787, exprimant AIDA-I en association avec d’autres facteurs de virulence, a démontré une différence significative pour les phénotypes d’invasion et de survie intracellulaire face à la souche de laboratoire exprimant AIDA-I.

Der Literaturskandal: Symbolisches Kapital und Selbstbezug am Beispiel Thomas Bernhards

Ce mémoire analyse la réception de l’auteur autrichien Thomas Bernhard (1931-1989) au regard des scandales qui ont marqué sa carrière. Tantôt identifié comme l’imprécateur de l’Autriche, tantôt comme écrivain exceptionnel, il aura remis en question le rôle de son pays dans le national-socialisme et multiplié les attaques ad hominem. Il aura tenu un rôle ambigu dans l’espace public. Tout en insistant sur le caractère fictif de ses œuvres, il se mettait en scène de façon provocatrice dans le discours public ainsi que dans sa fiction. Ce mémoire s’intéresse au fonctionnement du scandale en tant qu’événement social complexe ayant lieu dans l’espace public. Les chercheurs s’entendent pour considérer le scandale comme un trouble ou une irritation résultant d’une transgression, apparente ou avérée. Il s’agit en outre d’un phénomène intégré dans l’ordre social et géré par les médias, caractérisé par l’actualisation des valeurs morales. Dans la présente étude, il est postulé que le capital symbolique (cf. Bourdieu) joue un rôle d’a priori et de catalyseur dans les scandales. Une accumulation initiale de capital symbolique assure une visibilité médiatique automatique. Le capital d’identité de Thomas Bernhard – soit la personnalisation du capital symbolique – est hybride et complexe, de sorte qu’il est difficilement appréciable. La difficile appréciation du capital de l’auteur se traduit par l’incertitude des journalistes et du public quant à son message : réactions dispro-portionnées, critique du particulier perçue comme mise en cause de l’universel. Toute dé-claration, toute œuvre de Bernhard est assujettie à ses prestations « scandaleuses » antérieu-res. Ce mémoire insiste sur le caractère autoréférentiel du scandale et s’intéresse aux actes de langage performatifs (cf. John L. Austin). Le corpus comporte des romans de Bernhard, leurs recensions, des articles de quotidiens, des lettres de lecteurs, des documents juridiques ainsi que la correspondance entre Bernhard et Siegfried Unseld.
