Theoretical Investigation of the CO2 Capture Properties of γ-LiAlO2 and α-Li5AlO4
Authors: Duan Yuhua 
Published: September 2019

Aim:
The aim is to develop effective CO2 sorbent materials for fighting global climate
change.

Background:
CO2 is one of the major combustion products which once released into the air can contribute
to global climate change. There is a critical need for the development of new materials that can
capture CO2 reversibly with acceptable energy and cost performance for these applications. Accordingly,
solid sorbents have been reported to be promising candidates for CO2 sorbent applications
through a reversible chemical transformation due to their high CO2 absorption capacities at moderate
working temperatures.

Methods:
By combining first-principles density functional theory with phonon lattice dynamics calculations,
the thermodynamic properties of the CO2 capture reaction by sorbent as a function of temperature
and pressure can be determined without any experimental input beyond crystallographic structural
information of the solid phases involved. The calculated thermodynamic properties are used to evaluate
the equilibrium properties for the CO2 adsorption/desorption cycles.

Results:
Both γ-LiAlO2 and α-Li5AlO4 are insulators with wide band gaps of 4.70 and 4.76 eV, respectively.
Their 1st valence bands just below the Fermi level are mainly formed by p orbitals of Li, O
and Al as well as s orbital of Li. By increasing the temperature from 0 K up to 1500 K, their phonon
free energies are decreased while their entropies are increased. The thermodynamic properties of CO2
capture reactions by γ-LiAlO2 and α-Li5AlO4 are calculated and used for comparing with other wellknown
sorbent materials.

Conclusion:
The calculated thermodynamic properties of γ-LiAlO2 and α-Li5AlO4 reacting with CO2
indicate that LiAlO2 could be used for capturing CO2 at warm temperature range (500-800 K) while α-
Li5AlO4 could be used for capturing CO2 at high-temperature range (800-1000 K), which are in good
agreement with available experimental data.
Reorientation for National Transformation: the Role of Literature
Authors: Nnabuihe Chigozie Bright 
Published: September 2019

At the formative period of any human society, certain relevant orientations are conceived, designed and actualized to create awareness of what should be acceptable and/or unacceptable in human relationships. There are core values, norms and morals aimed at guiding the behaviour of the native population and making them aware of their place, time and identity within their society. The sole aim of such orientations is to ensure cohesion and a peaceful harmonious existence. Oral literature as it is referred to in this paper points to those literary artistic creations composed in oral form for the purposes of entertainment, edification and education. In the paper, we limit our discussions to the oral version of literature, drawing most of the excerpts from the works of oral Igbo literary artists. A few instances are also drawn from the written version as the need arises.

Memorializing a Legendary Figure: Bajajidda the Prince of Bagdad in Hausa Land
Authors: Liman Abubakar Aliyu 
Published: September 2019

This paper examines the various ways in which the Bayajidda legend is memorialized. In its current manifestations, the legend can be seen as an important agency for the remembrance of the past in the context of rapid socio-historical change in Africa, under the influence of modernity, technology and globalization. The analysis begins by highlighting the interface between folklore and history in everyday cultural practices in postcolonial northern Nigeria. The signposts that give a coherent structure to the paper include the chronicles of the Bayajidda legend, the essential oral version circulating in its different forms in Hausa society. Over the years, reference to the legend of Bayajidda has always been made through the use of different modes of cultural expression such as song, dramatic performance, film and other forms of narration. This range has served the political and ideological interests of the dominant power elite who are consistently alluding to the Bayajidda legend. The survival of the essential oral narrative therefore depends solely on a strategy of alluding to the legend in its various guises, including the form of museum artifacts, drama, films and musical songs. However, the paper explores each of the specific historical periods from the pre-colonial down to the colonial and postcolonial epochs with a view to highlighting how specific forms of the legend are deployed by hegemonic structures for the purposes of legitimation.

Assessment of the clinical accuracy of serum and saliva assays for identification of adverse food reaction in dogs without clinical signs of disease
Authors: Lam Andrea T. H. , Johnson Lily N. , Heinze Cailin R. 
Published: September 2019

Abstract

OBJECTIVE
To assess the clinical accuracy of 2 serum-based assays and 1 saliva-based assay for detection of adverse food reaction (AFR) in dogs without clinical signs of disease.

ANIMALS
30 healthy client-owned dogs.

PROCEDURES
Dog owners completed an online survey to collect comprehensive information about their pets' diet history. From each dog, serum and saliva samples were obtained and submitted for AFR testing by means of 3 assays that assessed the immunoglobulin response to 24 foods. Assays A and B measured food allergen–specific IgE concentrations in serum, whereas assay C measured food allergen–specific IgA and IgM concentrations in saliva. Descriptive data were generated, and Fisher exact tests were used to assess the respective associations between positive test results and specific food ingredients to which dogs were exposed.

RESULTS
Assays A, B, and C yielded positive results for 26, 18, and 30 dogs, respectively. All dogs had positive results for at least 1 assay. The median (range) number of foods or ingredients to which dogs tested positive was 10.5 (0 to 24) for assay A, 1 (0 to 13) for assay B, and 12.5 (4 to 22; IgM) and 3 (0 to 24; IgA) for assay C. Positive test results were not significantly associated with prior food exposure.

CONCLUSIONS AND CLINICAL RELEVANCE
Saliva and serum assays for AFR often yielded positive results for apparently healthy dogs and are not recommended for clinical use. Elimination diet trials remain the gold standard for diagnosis of AFR in dogs.
Iatrogenic cortical pseudoaneurysm following ventriculoperitoneal shunt insertion presenting with intraventricular hemorrhage
Authors: Verhey Leonard H. , Elder Theresa A. , Adel Joseph G. 
Published: September 2019

Background:Cerebral pseudoaneurysm formation associated with ventricular catheterization is an exceedingly rare complication that results from direct catheter-induced injury to a vessel. We report a case of intracerebral pseudoaneurysm formation associated with ventricular catheterization in a patient with hydrocephalus following aneurysmal subarachnoid hemorrhage.Case Description:The patient presented with aneurysmal subarachnoid hemorrhage and underwent partial endovascular embolization of the offending wide-necked basilar tip aneurysm with the plan for a Stage 2 stent-assisted coiling after initial recovery. Before discharge, a ventriculoperitoneal shunt (VPS) was placed for postaneurysmal hydrocephalus. Three weeks later, she presented with intraparenchymal and intraventricular hemorrhage. Angiography revealed a cortical aneurysm contiguous to the ventricular catheter of the VPS. She underwent microsurgical excision of the aneurysm, and a new VPS was placed after resolution of the intraventricular hemorrhage. She later underwent the second stage of the treatment and had an excellent neurological recovery to an independent state.Conclusion:Iatrogenic intracerebral pseudoaneurysm formation is an exceedingly rare complication of ventricular catheterization but is associated with significant mortality. Identifying a pseudoaneurysm in this context warrants prompt and definitive treatment with microsurgical or endovascular treatment.

An Emphirical Study On The Influence Of Store Resonance And Shopping Motivation On The Purchase Behaviour Among Supermarket Shoppers In Chennai
Authors: RAMPRABHA K. , VINOTH A. VINOTH 
Published: September 2019

The concepts and theories of consumer purchase behaviour have drawn upon various areas such as social psychology,sociology,psychology,economics and cultural anthropology.Shopping is the examining of goods or services from retailers with the objective of purchase at that time. Different people have different perceptions while they go for shopping. Some just love to shop and think that’s the best thing to do, which gives them happiness also. Some just do shopping just to get the necessary items that are their daily use items and don’t find shopping that much fun. Shopping motivation can be described as consumer’s wants and needs as they communicate with the outlets at which to make a purchase.Store resonance is the ultimate relationship between a store and a customer. The proximity of that bond between the store and the customer can be made preciseby using four factors: loyalty, emotional bond, being a member of the store community and active store involvement.This paper aims at store resonance and shopping motives that has an influence over the gender differences of the shoppers and to study the relationship between the store resonance and shopping motives that influence the purchase behaviour of the shoppers. It is identified thatthere is a significant difference between the shopping motivation and store resonance at 1 percent and 5 percent level. Thus it is concluded that with the increase in the store resonance shopping motivation is also increased.
