Wire-Bonding Reliability Evaluationa
Authors: Hossein Akbari Schlumberger 
Published: January 2021

Abstract
In microelectronic devices, wire bonding is the most common first-level interconnection method between die and lead. Failure of wire bonding causes component failure. Component failure may lead to system or sub-system failures, which often have very expensive consequences. Such failures are even more severe in the harsh operating conditions of the Oil and Gas industry, where services such as rig charge are extremely expensive. We have developed a robustness-evaluation method for microelectronic components using construction analysis.

Abstract
Silicon-Carbide (SiC) power devices have become a promising option for traditional Silicon (Si) due to the superior material properties. To fully take advantage of the SiC devices, a high-performance power device packaging solution is necessary. This study proposes a cost-effective double-sided cooled (DSC) 1.2 kV SiC half-bridge power module using organic epoxy-resin composite dielectric (ERCD) substrates. The high mechanical and thermal performance of the power module is achieved by the low-modulus, moderate thermal conductivity, and relatively thin (120 μm) layer of ERCD material compared with traditional metal-clad ceramic approaches. This novel organic dielectric can withstand high voltage (5 kV @ 120 μm) and operate up to 250°C continuously, which is indispensable for high power applications. The thermal modeling results show that the equivalent thermal resistance junction-to-case (Rjc_eq) of the DSC power module using dual direct bonded copper (DBC) is 17% higher than the dual ERCD configuration. Furthermore, a non-insulated DSC power module concept is proposed for maximizing thermal performance by considering thermal vias in the ERCD substrate and direct-soldered heat sink. A thought process for optimization of thermal via design is demonstrated and it shows up to 24% of improvement on thermal performance compared with the insulated DSC power module.
Uptake Rate of Hydrogen Getter for Effectively Removing Outgassed H2 from Microelectronic Packages

Published: January 2021

Abstract
Hydrogen absorption kinetic properties of palladium foil-based getter elements have been studied by manometric method based pressure amplitude measurement. The getter H2 uptake rate can be simply converted by pressure amplitude change, and can be fairly described by a mixed gas sorption modeling analysis. It has been found that the sorption rate of Pd-based getter element has a maximum rate of 40 ppm/min at initial absorption stage but it gets slowly down to 0.5ppm/min when approaching maximum sorption capacity, determined by a getter foil thickness. Based on different H2 outgassing rates of metal and polymer based package materials, a safety factor based methodology has been proposed for down selecting an appropriate getter element that can effectively removing outgassed H2 from microelectronic packages.
CYBERCRIME: THEORETICAL DETERMINANTS, CRIMINAL POLICIES, PREVENTION & CONTROL MECHANISMS
Authors: Khalifa Nasser AL-Dosari 
Published: January 2021

Purpose: The research aimed to explore the theoretical determinants of cybercrime in Qatar and assess how it can be prevented and minimised.
Methodology: This was done using the mixed method research design through the survey strategy and semi-structured interviews with experts in the field of cybercrime in Qatar. Having adopted a mixed-method research methodology, the study had a target population of 200 participants for questionnaire survey, while expert interview had a target population of 11 experts. All these participants were purposively sampled in pursuit of engaging respondents who had knowledge, experience and expertise in cybercrime, such as IT experts and professionals working on cyber security solutions, Lawyers, police officers working in cybercrime department in Qatar, and lawyers who had dealt with cybercrime. The results of the survey were quantified using the Likert scale and analysed quantitatively by the factor analysis, and frequency tables. The results of the interviews were analysed qualitatively.
Findings: The results of the survey revealed that the most typical types of cybercrime in Qatar include website hacking, email cyberattacks, and online banking cyberattacks. The predominant motive for cybercrime in the country is monetary gains. However, the findings from the logistic regression analysis reveal that different types of cybercrime are associated with different determinants, and online banking crimes are predominantly driven by monetary gains. Moreover, the findings from IT experts interviewed revealed various measures can be adopted as control measures of cybercrime activities and hazards, such as development of stronger networks by commercial companies to protect their cyber assets and use of up-to-date protective software that detect and ensures complete data security.
Unique contribution to theory, practice and policy: Further, the findings, in relation to the effective methods and mechanisms for preventing cybercrime, suggest that it can be reduced through the spread of awareness among people and companies and through the adoption of preventive control mechanisms. Further, the study recommends that governments should formulate and implement legislations aimed at enhancing stringent measures of combating and dealing with cybercrime in convergence with international standards and practices. Besides, companies should adopt technological cybersecurity solutions to enhance effective protection of intellectual property, intrusion, and malicious damage of data as well as other cyber-related crimes.
Polarised Facebook Discourse on Anglophone Nationalism in Cameroon
Authors: Ngouo Herbert Rostand 
Published: January 2021

Technological advances have decentralised public communication through networked digital communication. The present paper seeks to critically analyze Facebook contradictory discourses and conversations on the future of the English-speaking regions of Cameroon. In November 2016, the Anglophone population engaged in civil disobedience against the Government of Cameroon over nonchalant attitude towards its predicament or refusal to address its grievances. Focus is on trolls and polarized conversations and discourses made by Anglophone activists on Facebook regarding the socio-political crisis troubling Cameroon since the end of the year 2016. Using Critical Discourse Analysis (CDA) as a methodological and theoretical approach, this study shows that there are two opposing views on Facebook: the separatists’ and the pro-unionists’ positions. On the one hand, the separatist activists through their Facebook posts discourse repudiate the pan-Cameroonian identity which they associate with francophonisation and cultural assimilation, and promote a separate Anglophone nationalism. On the other hand, the pro-unity Anglophone activists defend national unity and reject the secessionist discourse, thereby reproducing and expressing their adherence to the Pan-Cameroonian identity. This study will try to go beyond linguistic elements analysis to include a systematic construction of the historical and political, sociological and/or psychological dimension in the analysis and interpretation of specific texts/discourse.

Abstract. The Filter Inlet for Gases and AEROsols (FIGAERO) coupled with a time-of-flight chemical ionization mass spectrometer (ToF-CIMS) enables online
measurements of both gas-phase and particle-phase chemical constituents of ambient aerosols. When properly calibrated, the incorporated particle
filter collection and subsequent thermal desorption enable the direct measurement of volatility of said constituents. Previously published
volatility calibration results however differ from each other significantly. In this study we investigate the reason for this discrepancy. We found
a major source of error in the widely used syringe deposition calibration method that can lead to an overestimation of saturation vapour pressures
by several orders of magnitude. We propose a new method for volatility calibration by using atomized calibration compounds that more accurately
captures the evaporation of chemical constituents from ambient aerosol particles. For example, we found a difference of ∼ 15 ∘C
in observed Tmax⁡ values between the atomizer method and syringe method using the lowest solution concentration (0.003 g L−1). This
difference translates into a difference of up to 3 orders of magnitude in saturation concentration C∗ space. We justify our claim with evaporation
modelling and direct scanning electron microscopy imaging, while also presenting possible error sources of the atomizer method. We finally present
how typical calibration parameters derived with both methods impact the volatility basis set (VBS) derived from measurements of secondary organic
aerosols (SOAs).
Pedagogy and the Politics of Organizing in Mississippi
Authors: Nadasen Premilla 
Published: January 2021

This article reflects on a community-directed collaboration between students at a four-year liberal arts institution and a local organization in Mississippi to develop an index of women's economic security. It suggests that the collaborative nature of the course, as well as the relationship- and community-building witnessed in Mississippi offer counter-narratives to liberal individualism, southern conservatism, and the practice of social justice work.
Collective Visioning: Igniting the Radical Imagination
Authors: York Matt 
Published: January 2021

As the spaces which once existed within the university for the co-imagining of liberatory political praxes diminish, social movements are increasingly reverting to methods of collective visioning which have been developed on the streets to theorise radical social change. I argue that such methodologies provide important opportunities for a reappraisal of our hierarchical student/teacher relations, and make the case that we can collectively learn much more from within our movements than anyone might hope to teach us from outside. The article traces our current movement wave, and locates contemporary forms of collective visioning within a wider lineage of knowledge co-production in social movements. The neoliberal subversion of university education is examined, and proposals made for ways in which we might challenge these hegemonic conditions. I conclude that the liberatory epistemologies and forms of knowledge co-production explored in this article offer significant potential for developing new modes of praxis for our current wave of ecological and anti-capitalist activists both inside and outside the university.

Published: January 2021

The forest of Bissa is a Mediterranean ecosystem, characterized by a high floristic diversity. In order to assess the floristic diversity in this forest, 133 floristic readings were conducted in this area between 2013 and 2017. As a result, it was possible to identify 151 species, 125 genus and 54 botanical families, with a clear dominance of Asteraceae, Fabaceae and Poaceae. Biologically, this ecosystem was mainly dominated by therophytes (37%). Physiognomically, the phanerophytes were the most dominant types, whereas in term of phytogeography this forest was dominated by the Mediterranean type (50%). According to Shannon-Winner index, this area was characterized by a relatively low diversity (1.3 bit / ind), with a clear dominance of a few species. Finally this forest was relatively disturbed (42%) and under a strong anthropozoic influence.
Modelo de evaluación de la efectividad, continuidad y conectividad del sistema de áreas protegidas costeras mediante el análisis de su flora y vegetación

Published: January 2021

Los ecosistemas litorales están fuertemente amenazados por el aumento del nivel del mar, las inundaciones y la litoralización de la población. Aunque se ha intensificado el esfuerzo por declarar áreas protegidas costeras, estas quedan fragmentadas en teselas circundadas por territorios artificalizados. La conectividad entre estas áreas protegidas es por tanto la garantía de la continuidad de los servicios ecosistémicos que proveen. Se propone un modelo para la evaluación de la eficacia potencial del sistema continuo de las áreas protegidas costeras en base al conocimiento de su flora y vegetación. El grado de efectividad pretende ser un indicador para la adopción de medidas de planificación territorial conducentes al fortalecimiento de la red como medida de salvaguarda de la biodiversidad. Para probar el modelo propuesto se ha elegido la costa de Andalucía (S de España), territorio bañado por el Mediterráneo y el Atlántico, susceptible de importantes impactos. Este segmento de costa ha sido sometido durante los últimos 60 años a fuertes presiones de origen antrópico.que han fragmentado y alterado la estructura, composición y funcionalidad de los ecosistemas litorales. Todo ello pone en riesgo tanto los valores que sirvieron para la declaración de un status de protección como la conectividad entre ecosistemas que garanticen la persistencia de sus servicios ecosistémicos. La metodología propuesta para medir la eficacia potencial del sistema se sustenta en el grado de protección legal, el valor fitocenótico y el grado de artificialización. A partir de la integración de los valores obtenidos se ha calculado la consistencia de los nodos y en definitiva la efectividad en red. La aplicación de este método pone de relevancia cuales son las áreas protegidas más vulnerables ante las deficiencias de la red, en especial por las dificultades de conectividad.
Surgical Resection of a Parietal Osteoma in a Domestic Ferret Using Advanced Neurosurgical Techniques
Authors: Paushter Aaron , Early Peter , Perkins Tyler , Applegate Jeffrey 
Published: January 2021

ABSTRACTA 3.5 yr old male neutered ferret presented with progressive enlargement of a right dorsocaudal skull mass that had occurred over 18 mo. Computed tomography imaging revealed a large (2.4 × 2.7 cm), well-defined, pedunculated osseous mass arising from the right parietal bone. Cytology was inconclusive, and surgical biopsy was consistent with an osteoma. Further enlargement of the mass occurred over the next 3 mo, at which time surgical intervention was pursued. The patient recovered well, despite the persistence of a bony defect at the former mass site, and no mass regrowth occurred in the 14 mo following the surgical resection. This is one of only two reports in the literature to document the surgical removal of an osteoma in a ferret, and this is the sole case in which a custom apparatus was fabricated for head stabilization, a multiaxis adjustable surgical table was used to improve access to the surgical site, and an ultrasonic scalpel was used for the mass resection.
Geology, Structural Analysis, and Paragenesis of the Arrow Uranium Deposit, Western Athabasca Basin, Saskatchewan, Canada: Implications for the Development of the Patterson Lake Corridor
Authors: Hillacre Sean , Ansdell Kevin , McEwan Brian 
Published: January 2021

Abstract
Recent significant discoveries of uranium mineralization in the southwestern Athabasca basin, northern Saskatchewan, Canada, have been associated with a series of geophysical conductors along a NE- to SW-trending structural zone, termed the Patterson Lake corridor. The Arrow deposit (indicated mineral resource: 256.6 Mlb U3O8; grade 4.03% U3O8) is along this trend, hosted exclusively in basement orthogneisses of the Taltson domain, and is the largest undeveloped uranium deposit in the basin. This study is the first detailed analysis of a deposit along this corridor and examines the relationships between the ductile framework and brittle reactivation of structures, mineral paragenesis, and uranium mineralization. Paragenetic information from hundreds of drill core samples and thin sections was integrated with structural analysis utilizing over 18,000 measurements of various structural features. The structural system at Arrow is interpreted as a partitioned, strike-slip–dominated, brittle-ductile fault system of complex Riedel-style geometry. The system developed along subvertical, NE- to SW-trending dextral high-strain zones formed syn- to post-D3 deformation, which were the focus of extensive premineralization metasomatism (quartz flooding, sericitization, chloritization), within the limb domain of a regional-scale fold structure. These zones evolved through post-Athabasca dextral and sinistral reactivation events, creating brittle fault linkages and dilation zones, allowing for hydrothermal fluid migration and resulting uraninite precipitation and associated alteration (white mica, chlorite, kaolinite, hematite, quartz veins). This study of the structural context of Arrow is important as it emphasizes that protracted reactivation of deep-seated structures and their subsidiaries was a fundamental control on uranium mineralization in the southwestern Athabasca basin.
