Hawking Radiation via Tunneling from Hot NUT-Kerr-Newman-Kasuya Spacetime

We study the Hawking thermal spectrum in dragging coordinate system and the tunneling radiation characteristics of hot NUT-Kerr-Newman-Kasuya spacetime. The tunneling rates at the event and cosmological horizon are found to be related to the change of Bekenstein-Hawking entropy. The radiation spectrum is not pure thermal and thus there is a correction to the Hawking thermal spectrum.Comment: To appear in Class. Quant. Gra

The Hiring Entity’s Usual Course of Business

The ABC test has increasingly become a tool to differentiate employees from independent contractors. Companies and counsel throughout the nation have grappled with Part B of this test, which requires a determination of the hiring entity’s “usual course of business.” Adjudicators have provided little guidance on how to conduct this analysis and are admittedly frustrated with this “elusive concept.” Yet a thorough treatment of the analytical framework and guiding principles of Part B of the ABC Test has not been put forth. This article fills this void in scholarship. By tracing the relevant concepts to the common law control test, and more importantly, a lesserknown framework analyzing skill and integration to determine liability, in addition to articulating the genesis and proliferation of the ABC Test within unemployment insurance legislation, this article answers a call from the judiciary to locate the origins of the ABC Test. Assessing decisions from state supreme courts and intermediate appellate bodies, this article then examines three methods courts use to determine whether work was done outside the usual course of the hiring entity’s business. The principal insight of this article is that work which is in the hiring entity’s usual course of business is work which provides regular aid to the business. This article concludes by analyzing two related questions within the Part B framework: (1) whether the Part B test is work-specific or worker-specific, a question of salience given the use of class actions, and (2) how to describe the hiring entity’s business, a question of import due to the rise of the gig economy

Utilization of Agro-Residual Ligno-Cellulosic Substances by Using Solid State Fermentation: A Review

Agro-residual wastes contain many usable substrates of high value such as carbohydrates and fi bers. Direct disposal of these wastes as burning or landfill will cause serious environmental problems. Thus, designing new methods for exploitation and treatment of these wastes to produce useful products with great economic advantages are substantial. Solid state fermentation (SSF) has become an attractive method in recent years due to its features of using these wastes directly as raw materials or substrates. Thus, SSF is considered as an environmentally-friendly technique for waste treatment. This paper reviews the exploitation of the agro-residual wastes through SSF technology

Evaluation of Hepcidin Hormone and Some Biochemical Parameters in Iraqi Children Patients with β-Thalassaemia Intermedia Before and After Blood Transfusion

Background:"thalassaemia" refers to a group of blood diseases characterized by low or absent synthesis of normal globin chains. Depending on the chain whose synthesis is impaired, the thalassaemias are called α‒, β‒,ɣ‒ ,σ‒ or ԑɣσβ-thalassaemias . Most thalassaemias are inherited as recessive traits.Objective: the aim of this study is evaluated hepcidin levels, transferrin, ferritin, serum iron and total iron bending capacity [TIBC] before and after blood transfusion of thalassaemia patients.Methods: In this study, we take 80 persons the age of them were mean±SD (9.68±2.08), 40 patients with β-thalassaemia intermedia, and 40 healthy persons as control. We take blood 5ml from thalassaemia's patients before blood transfusion and after transfusion of blood by 3 days. The total number of the samples we taken are 120, 40 samples before blood transfusion, 40 samples after blood transfusion and 40 control samples. Then we separated each sample into two tubes.Result: increase iron absorption of thalassaemia patient after blood transfusion due to decrease level of hepcidin.Conclusion: from this study was appear iron absorption meanly affect by hepcidin level, so that hepcidin was highly significant change in thalassaemia patient after blood transfusion and that lead to iron overload. So conclude high levels of ferritin after blood transfusion due to blood uptake lead to increase iron storage (ferritin). Keywords: β-thalassaemia intermidia, hepcidin, serum iron and ferritin (iron storage)
