Point Absorber Wave Energy Harvesters: A Review of Recent Developments

Even though ocean waves around the world are known to contain high and dense amounts of energy, wave energy harvesters are still not as mature as other forms of renewable energy harvesting devices, especially when it comes to commercialization, mass production, and grid integration, but with the recent studies and optimizations, the point absorber wave energy harvester might be a potential candidate to stand out as the best solution to harvest energy from highly energetic locations around the world’s oceans. This paper presents an extensive literature review on point absorber wave energy harvesters and covers their recent theoretical and experimental development. The paper focuses on three main parts: One-body point absorbers, two-body point absorbers, and power take-offs. This review showcases the high amount of work being done to push point absorbers towards technological maturity to eventually kick off commercialization and mass production. It should also provide a good background on the recent status of point absorber development for researchers in the field.
w M h l y, Immunophenotype and Cytogenetic Analysis of Childhood/ Adult Acute Lymphoblastic Leukemia in Omani Patients

Genetic changes associated with acute lymphoblastic leukemia (ALL) provide very important diagnostic and prognostic information with a direct impact on patient management. Detection of chromosome abnormalities by conventional cytogenetics combined with fluorescence in situ hybridization (FISH) play a very significant role in assessing risk stratification. Identification of specific chromosome abnormalities has led to the recognition of genetic subgroups based on reciprocal translocations, deletions and modal number in B or T-cell ALL. In the last twelve years 102 newly diagnosed childhood/adult ALL bone marrow samples were analysed for chromosomal abnormalities with conventional G-banding, and FISH (selected cases) using specific probes in our hospital. G-banded karyotype analysis found clonal numerical and/or structural chromosomal aberrations in 74.2% of cases. Patients with pseudodiploidy represented the most frequent group (38.7%) followed by high hyperdiploidy group (12.9%), low hyperdiploidy group (9.7%), hypodiploidy (<46) group (9.7%) and high hypertriploidy group (3.2%). The highest observed numerical chromosomal alteration was high hyperdiploidy (12.9%) with abnormal karyotypes while abnormal 12p (7.5%) was the highest observed structural abnormality followed by t(12;21)(p13.3;q22) resulting in ETV6/RUNX1 fusion (5.4%) and t(9;22)(q34.1;q11.2) resulting in BCR/ABL1 fusion (4.3%). Interestingly, we identified 16 cases with rare and complex structural aberrations. Application of the FISH technique produced major improvements in the sensitivity and accuracy of cytogenetic analysis with ALL patients. In conclusion it confirmed heterogeneity of ALL by identifying various recurrent chromosomal aberrations along with non-specific rearrangements and their association with specific immunophenotypes. This study pool is representative of paediatric/adult ALL patients in Oman. currently
Failures’ Study of a New Character Three - Phase High Voltage Supply for industrial Microwave Generators with one magnetrons per Phase

This article treats the development of one of the equivalent electrical models for a single phase power supply for one magnetron; in particular that of its own high voltage (HV) transformer newly dimensioned. This single phase system supplies a voltage doubler and current stabilizer circuit, which supplies a single magnetron. Then, by star connecting the three identical models of the single-phase power supply for one magnetron, we obtain a new character three-phase high voltage power supply for industrial microwave generators with one magnetron per phase. The simulation with EMTP (Electro Magnetic Transcients Program) in nominal operation has given the theoretical results close to the experimental measurements. Finally, the magnetrons’ failure of the microwave generator was also treated and allowed to observe the interaction’s influence between magnetrons; also the regulation of the anode current has been achieved successfully.
Effects of Labless Kits On Senior Secondary School Students’ Academic Performance in Physics in Osun State

This study examined the effects of Labless kits on senior secondary school students’ academic performance in Physics in Osun state. Specifically, the research determined which of Labless kits and conventional laboratory would provide better academic performance in Physics. The study adopted the quasi- experimental pre-test, post-test control group design. The sample consisted of 206 students drawn from six public secondary schools in Osun State. The selection of the sample was done using multistage sampling technique. Two Senatorial districts were randomly selected from the three senatorial districts in Osun. Three Local Governments were randomly selected from each of the two senatorial districts earlier selected, making a total of six Local governments selected. One public secondary school was randomly selected from each of the six local governments chosen for the study. An intact class from each of the six selected schools was used for the study. Purposive sampling technique was used to assign the schools into labless kits and laboratory groups respectively. Physics Achievement Test (PAT) was developed, validated and used to generate the data for the study. The research question raised was answered descriptively while the three hypotheses generated were tested using t- test and Analysis of Covariance (ANCOVA). The result of the study showed that the use of labless kits produced better students’ academic performance in Physics than using conventional laboratory. The use of labless kits helped the students to achieve maximally in Physics during teaching as this was revealed in their performance. Based on the findings, the use of Labless kits should be encouraged in the teaching of Physics in secondary schools. Physics teachers should be given adequate orientation through workshops and seminars to update their knowledge in the use of Labless kits strategy in teaching.
The Geometry of Large Rotating Systems

This paper presents an analytical solution to the geometry of large rotating systems which reconciles the peculiar rotation profiles of distant galaxies with Einstein's principle of General Relativity. The resulting mathematical solution shows that large rotating systems are distorted in the space of a non-rotating observer into a spiral pattern with tangential velocities that behave in agreement with those observed in distant galaxies. This paper also demonstrates how the scale of the spiral structure of rotating systems can be used to determine its distance from the observer. The authors' proposed equations for the rotation pro le and the distance measure are compared with the observed rotation pro les and Cepheid distance measurements of several galaxies with strong agreement. A formal error analysis is not included however the authors suggest a method for better qualifying the accuracy of the theorums.
University of Birmingham Delivery of anthropogenic bioavailable iron from mineral dust and combustion aerosols to the ocean

Atmospheric deposition of anthropogenic soluble iron (Fe) to the ocean has been suggested to modulate primary ocean productivity and thus indirectly affect the climate. A key process contributing to anthropogenic sources of soluble Fe is associated with air pollution, which acidi-ﬁes Fe-containing mineral aerosols during their transport and leads to Fe transformation from insoluble to soluble forms. However, there is large uncertainty in our estimate of this anthropogenic soluble Fe. In this study, for the ﬁrst time, we interactively combined laboratory kinetic experiments with global aerosol modeling to more accurately quantify anthropogenic soluble Fe due to air pollution. Firstly, we determined Fe dissolution kinetics of African dust samples at acidic pH values with and without ionic species commonly found in aerosol water (i.e., sulfate and oxalate). Then, by using acidity as a master variable, we constructed a new empirical scheme for Fe release from mineral dust due to inorganic and organic anions in aerosol water. We implemented this new scheme and applied an updated mineralogical emission database in a global atmospheric chemistry transport model to estimate the atmospheric concentration and deposition ﬂux of soluble Fe under preindustrial and modern conditions. Our improved model successfully captured the inverse relationship of Fe solubility and total Fe loading measured over the North Atlantic Ocean (i.e., 1–2 orders of magnitude lower Fe solubility in northern-African- than combustion-inﬂuenced aerosols). The model results show a positive relationship between Fe solubility and water-soluble organic carbon (WSOC) / Fe molar ratio, which is consistent with previous ﬁeld measurements. We estimated that deposition of soluble Fe to the ocean in-creased from 0.05–0.07 Tg Fe yr − 1 in the preindustrial era to 0.11–0.12
Integration of Thermoelectric Generator and Wireless Sensor Node Simulators

Collaborative research among Idaho National Laboratory, Boise State University, and the University of Houston under the Nuclear Energy Enabling Technologies Program’s Advanced Sensors and Instrumentation Pathway aims to develop efficient and reliable thermoelectric generators (TEGs) for self-powered wireless sensor nodes (WSNs) for nuclear applications. The power harvesting technology has crosscutting significance to all U.S. Department of Energy Office of Nuclear Energy research and development programs, because the technology will enable self-powered WSNs in multiple nuclear reactor designs and spent fuel storage facilities using thermal energy available in a nuclear power plant or spent fuel storage facility. This project will address the technology gap that exists in realizing truly wireless sensor nodes due to the need for cables to connect to external power supplies and develop thermoelectric (TE) power harvesting devices to deliver sufficient power to drive the WSNs. The outcomes of the project will lead to significant advancement in sensors and instrumentation technology, reducing cost, improving monitoring reliability, and therefore enhancing safety. The self-powered WSNs could support the long-term safe and economical operation of all reactor designs and fuel cycle concepts, as well as spent fuel storage and many other nuclear science and engineering applications.
Transcription Factors in the Intertwining of Adipogenesis and Osteoclastogenesis

A key finding in the field of osteoclast development was that among all the hematopoietic stem cell and progenitor populations in bone marrow, those that express PPARγ are specifically endowed with the ability to commit into the osteoclast lineage [1]. Using in vivo lineage tracing strategies with PPARγ-tTA TREH2BGFP reporter mice, Wei et al. (2011) demonstrated that osteoclasts are derived from PPARγ-expressing cells of the hematopoietic lineage [1]. The GFP+ PPARγ+ but not the GFPPPARγbone marrow cells derived from the PPARγ-tTA TRE-H2BGFP reporter mice differentiated into mature osteoclasts when cultured under osteoclastogenic conditions indicating that the osteoclastogenic precursor population lies within the PPARγ+ bone marrow subpopulation. Further, the impact of PPARγ-expressing hematopoietic subsets on bone homeostasis was confirmed by selective depletion of PPARγ+ cells in mice [1]. This was achieved using a novel transgenic mouse model generated by crossing transgenic mice expressing Cre recombinase under the control of the PPARγ promoter driven tetracycline-controlled transactivator protein (tTA) combined with a tetracycline-responsive promoter element (TRE)-Cre transgene (PPARγ-tTA TRE-Cre) with a second line of transgenic mice that exhibited conditional expression of diphtheria toxin (DTA) in the presence of Cre (DTA-floxed). This resulted in the selective ablation of PPARγ progenitors, ablation of osteoclast differentiation and an osteopetrotic (abnormally dense bone) phenotype in the offspring [1]. Furthermore, specific activation of Notch in the PPARγ progenitor cell populations by breeding the PPARγtTA TRE-Cre mice with a constitutively active Notch Intracellular Domain (NICD)-floxed mice suppressed osteoclast differentiation. This is consistent with a role for Notch activation in the suppression of PPARγ signaling in osteoclastogenic cells [1] that is analogous to the suppression of adipogenesis in MSCs by Notch [2,3–6]. Taken together, these studies indicate that PPARγ activation can induce adverse effects on skeletal homeostasis through the combined effects of reduced bone formation due to suppression of MSC osteoblastogenesis on one hand, and exacerbated bone resorption due to increased HSC osteoclastogenesis on the other.
Renoprotective Effects Of Isoliquiritin Against Cationic Bovine Serum Albumin-Induced Membranous Glomerulonephritis In Experimental Rat Model Through Its Anti-Oxidative And Anti-In ﬂ ammatory Properties

Background: Membranous glomerulonephritis (MGN) is a nephrotic syndrome which shows the symptoms of heavy proteinuria and immune complex deposition in glomerular subepithelial space and ﬁ nally leads to chronic kidney disease. Isoliquiritin (ILQ) is a ﬂ avonoid with a wide range of pharmacological properties, including antioxidant and anti-in ﬂ ammatory activity. The present study was undertaken to investigate the possible mechanisms by which ILQ ameliorates cationic bovine serum albumin (C-BSA) induced MGN in rat model. Methods: The MGN condition was con ﬁ rmed by the 24 hr proteinuria and ILQ (10 mg/kg/bw/ day) or TPCA-1 (10 mg/kg/bw/day; IKK β inhibitor) was administered to successfully induce rats for 4 weeks. Results: The present study revealed that MGN rats treated with ILQ showed signi ﬁ cantly ameliorated kidney dysfunction and histopathological changes in kidneys. ILQ treated MGN rats alleviated the oxidative stress and were presented with increased anti-oxidative status in kidneys. Furthermore, ILQ treatment to MGN rats showed anti-oxidative effects through the prominent stimulation of Nrf2 signaling pathway and inhibition of Keap1, which conse-quently increases the Nrf2 nuclear translocation and thereby induces expression of NQO1 and HO-1. In addition, ILQ-treated MGN rats demonstrated anti-in ﬂ ammatory effects by inhibiting NF- κ B signaling pathway through decreased mRNA and protein expressions of NF- κ B p65, IKK β , COX-2, iNOS, p38-MAPK, p-p38-MAPK, TNF- α , IL-1 β , IL-8, ICAM-1, E-selectin and VCAM-1 and reduced the nuclear translocation of NF- κ B p65. Conclusion: The protective effect of ILQ on MGN can be explained by its anti-oxidative and anti-in ﬂ ammatory activities, which in turn due to the activation of Nrf2 and downregulation of NF- κ B pathway.
How age of initiation of alcohol use influences severity of alcohol consumption: An observation from Nepal

Introduction: With the ever -increasing prevalence of AUD in Nepal, there arises an increasing need to better understand the complexities of factors that influence alcohol use. The objective of this paper is to evaluate the association between several alcohol use characteristics and severity of alcohol use disorder.Methods: A cross-sectional study was conducted in 8 alcohol and drug rehabilitation centers (residential treatment centers) of Kathmandu, Nepal, involving 225 male patients. The AUDIT test was used to screen patients with AUD. A self-report questionnaire was developed to measure socio-demographic characteristics and alcohol use characteristics (which included age of initiation of alcohol use, previous admission at rehabilitation centers/hospitals for alcohol-related problems, and previous abstinence attempts). Results: Among the patients screened positive for AUD, 75% were screened to have alcohol dependence while 25% were screened to have harmful use. Thirty- two percent of the patients initiated alcohol use before the age of 18, 90% had previous abstinence attempts and over 50% had previous admission at rehabilitation centers or hospitals due to alcohol-related problems. A statistically significant association was found between the age of initiation of alcohol use and severity of alcohol use disorder where those who initiated alcohol use before the age of 18 were assessed to be more likely to develop severe AUD (alcohol dependence). Discussion: Early age of initiation of alcohol use is associated more severe AUD later on in life. However, further studies may be needed to consolidate the findings from this study.
Survival of the fittest: the impact of fit between warehouse management structure and warehouse context on warehouse performance

Warehouse operations are vital for the success of a supply chain. This paper explores fit among warehouse management structure and the context in which the warehouse operates as an important driver of warehouse performance. Warehouse management structure has been operationalised as the extensiveness by which warehouse operations are planned and controlled, and the complexity of the decision rules used for optimisation of the operations. Warehouse performance is measured using data envelopment analysis (DEA). Hypotheses are developed and tested in a survey study among 111 distribution warehouses in the Netherlands and Belgium. Our results show that indeed warehouse management structure should be adapted to context. In order to obtain high warehouse performance more complex warehouse tasks require more and more complex decision rules, and warehouses with more unpredictable demand require fewer tactical plans. These results can help warehouse managers to structure their warehouse management contingent on the context in which the warehouse operates.
(2018). How Culture Influences the Perception of Online Consumer Reviews. (9),

Online Consumer Reviews (OCRs) developed to an important and influential online-tool over the past years. While previous research focused on OCRs´ influence on purchase intention and sales, little attention was paid on how consumers´ cultural value orientation might influence the perception of these reviews. Addressing this important research gap this study investigated how consumer’s cultural value orientation along Hofstede´s dimensions influence the perceived importance of OCRs. Using a cross-sectional online survey, the study finds that cultural value orientation partly moderates the relationship between OCRs´ attributes and the perceived importance of OCRs significantly. These results might indicate a shrinking influence of cultural values on consumer behaviour when using online shopping websites, which was suggested by previous studies. These findings have significant implications for the theory and practice of international retail management .
Computational Prediction of Isolated Performance of an Axisymmetric Nozzle at Mach Number 0.90

An improved ability to predict external propulsive performance was incorporated into the three-dimensional Navier-Stokes code PAB3D. The improvements are the ability to account for skin friction and external pressure forces. Performance parameters for two axisymmetric supersonic cruise nozzle configurations were calculated to test the improved methodology. Internal and external flow-field regions were computed using a two-equation kappa-epsilon turbulent viscous-stress model. The computed thrust-minus-drag ratios were within 1 percent of the absolute level of experimental data and the trends of data were predicted accurately. The predicted trend of integrated nozzle pressure drag matched the trend of the integrated experimental pressure drag over a range of nozzle pressure ratios, but absolute drag levels were not accurately predicted.
A RELATION BETWEEN HOCHSCHILD HOMOLOGY AND COHOMOLOGY FOR GORENSTEIN RINGS

The paper [5] contains an error in the sense that Theorem 1 (the “duality theorem”) is false in the generality stated. As a result the same is true for its corollaries: Proposition 3 and Corollary 6. The main conclusion, which is an affirmative answer to a question by Patrick Polo, remains valid however (see below). That Theorem 1 is false as stated was pointed out in [2]. In general it can be seen as follows. If the conclusion of Theorem 1 is true, then the Hochschild dimension (the cohomological dimension of HH∗) of the ring A is finite. So Theorem 1 must be false for every ring of infinite Hochschild dimension, and hence in particular for every ring of infinite global dimension. Thus to save Theorem 1 we must assume that A has finite Hochschild dimension (let us say that A is smooth in this case). It is easy to see that in that case the proof becomes valid. The smoothness hypothesis is automatically satisfied in Proposition 2 (see [4]) but it must be added in Proposition 3 and Corollary 6. The following lemma shows that smoothness is a reasonable condition.

How Digital Information Transforms Project Delivery Models

This study articulates how increasingly pervasive digital information transforms project delivery models. It builds on and extends the literature on innovation and knowledge codification, analyzing London’s evolving digital innovation ecosystem across 15 years of industry/government initiatives and infrastructure megaprojects. Findings suggest profound and ongoing changes in digitally enabled project delivery models. Novel contributions are: first, to identify new generations of integrated solutions; second, to articulate changes in supply chains and relationships with owners, operators, and end users; and third, to recognize the growing importance of digital workflows and analytics, rather than documents. There are implications for project management practice and scholarship.
