EVALUATION OF A NOVEL ALLOPLASTIC BIOMATERIAL IN A RAT CALVARIAL DEFECT MODEL: A PILOT STUDY
Creators: name: Gohel, Vishal
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Aim: To evaluate bone regeneration using two novel alloplastic biomaterials in a “critical” size, rat calvarial defect model using microcomputed tomography (µCT).      Methods and Materials: Fifty-six, adult, male, Sprague-Dawley rats, 11-12 weeks old, weighing 310-510g were randomized into 8 groups of 7 animals. An 8-mm “critical” size calvarial defect was created, and each group received one of the following treatments: sham surgery (negative control), deproteinized bovine bone mineral (DBBM) + collagen membrane (CM) (positive control), PLGA coated pure phase β-tricalcium phosphate (TCP), PLGA coated 60% hydroxyapatite (HA):40% β-TCP composite. The groups were divided into two- and six-week healing intervals. µCT was used to evaluate mineralized tissue inside the defect and biomaterial displacement.      Results: Significantly greater mineralized tissue volume was observed in the biomaterial groups when compared to the sham controls at both time points; no significant differences were observed among biomaterials. There was an increase in mineralized tissue from two to six weeks. Biomaterial vertical displacement was greatest at two weeks, and decreased by six weeks. Vertical displacement could largely be explained by hematoma formation under the biomaterial. Lateral displacement was minimal for the candidate biomaterials, but significantly greater for the DBBM group, despite the use of a membrane.       Conclusions: Within the limits of this study, biomaterials yielded significantly higher mineralized tissue volume, a proxy for bone regeneration, when compared to an unfilled control in a “critical” size rat calvarial defect. PLGA coated β-TCP and PLGA coated HA/β-TCP showed comparable bone formation to DBBM covered by a collagen barrier membrane. These biomaterials also demonstrated less lateral displacement than the DBBM group, and were able to maintain their form throughout the duration of the study. PLGA coated β-TCP and PLGA coated HA/β-TCP can be considered viable alternatives to DBBM for bone augmentation procedures, and appear to function well without the need for a barrier membrane. Histological analysis is needed to qualify the nature of the mineralized tissue observed.

description: A proper edge $k$-colouring of a graph $G=(V,E)$ is an assignment $c:E\to \{1,2,\ldots,k\}$ of colours to the edges of the graph such that no two adjacent edges are associated with the same colour. A neighbour sum distinguishing edge $k$-colouring, or nsd $k$-colouring for short, is a proper edge $k$-colouring such that $\sum_{e\ni u}c(e)\neq \sum_{e\ni v}c(e)$ for every edge $uv$ of $G$. We denote by $χ'_{\sum}(G)$ the neighbour sum distinguishing index of $G$, which is the least integer $k$ such that an nsd $k$-colouring of $G$ exists. By definition at least maximum degree, $Δ(G)$ colours are needed for this goal. In this paper we prove that $χ'_Σ(G) \leq Δ(G)+1$ for any graph $G$ without isolated edges and with ${\rm mad}(G)<3$, $Δ(G) \geq 6$.

Anisotropic cosmology and inflation from tilted Bianchi IX model

description: The dynamics of the tilted axisymmetric Bianchi IX cosmological models are explored allowing energy flux in the source fluid. The Einstein equations and the continuity equation are presented treating the equation of state $w$ and the tilt angle of the fluid $λ$ as time dependent functions, but when analysing the phase space $w$ and $λ$ are considered free parameters and the shear, the vorticity and the curvature of the spacetime span a three-dimensional phase space that contains seven fixed points. One of them is an attractor that inflates the universe anisotropically, thus providing a counter example to the cosmic no-hair conjecture. Also, examples of a realistic though fine-tuned cosmologies are presented wherein the rotation can grow significant towards the present epoch but the shear stays within the observational bounds. The examples suggest that the model used here can explain the parity-violating anomalies of the cosmic microwave background. The result significantly differs from an earlier study, where a non-axisymmetric Bianchi IX type with a tilted perfect dust source was found to induce too much shear for observationally significant vorticity.

Year: 2020

description: Despite lakes being key part of the global water cycle and a crucial water resource, there is limited understanding of how water storage in small lakes varies over time. Here, we study change in lake water storage over time in clusters of small natural lakes in North Carolina, Washington, Illinois, and Wisconsin, using lake level measurements gathered by citizen scientists and lake surface area measurements taken from optical satellite imagery. We compare the change in lake water storage between pairs of lakes within regional clusters. On average, water storage variations in lakes across all study regions are moderately positively correlated (rho = 0.49) with substantial spread in the degree of correlation. Overall, there is a weak, but statistically significant, negative relationship between distance and paired lake correlations. This study addresses a gap in understanding about small lakes and provides a baseline about regional patterns of change in lake water storage.

description: In order to improve the production of acarbose, the fermentation medium of acarbose-producing strain Actinoplanes sp. KCTC 9161 – L14 mutant was optimized in this internship. Fractional factorial design was employ to investigate the influences of glucose, maltose and corn power on acarbose production (by a-glucosidase inhibitory ability). Two significant factors: glucose and maltose have significant and positive effects on acarbose amount. In addition, a model was obtained from the regression results of fractional factorial experiment. Other success, we demonstrated that chromatography by active charcoal column can used to purify acarbose from fermentation broth. Acarbose amount in purification solution was 191.5 g/L and an acarbose - purification process was inducted. Nhằm mục đích nâng cao khả năng sinh tổng hợp hoạt chất acarbose từ chủng đột biến Actinoplanes sp. KCTC 9161-L14, môi trường lên men của chủng dùng để sản xuất acarbose đã được tối ưu hóa. Một phần mềm thiết kế đã được thiết lập để khảo sát ảnh hưởng của glucose, maltose và bột ngô đến khả năng sản xuất acarbose (thông qua hoạt tính ức chế -glucosidase). Kết quả đã cho thấy, hai yếu tố glucose và maltose có ý nghĩa quan trọng và ảnh hưởng trực tiếp đến khả năng sinh tổng hợp acarbose. Một phương trình đã được hình thành từ kết quả tối ưu. Bên cạnh đó, chúng tôi đã chứng minh được cột sắc ký sử dụng than hoạt tính có thể tinh sạch acarbose từ dịch lên men. Hàm lượng acarbose trong dung dịch tinh sạch đạt 191,5 g/l và một quy trình tinh sạch acarbose được đề xuất.

description: We study the common ancestor type distribution in a $2$-type Moran model with population size $N$, mutation and selection, and in the deterministic limit regime arising in the former when $N$ tends to infinity, without any rescaling of parameters or time. In the finite case, we express the common ancestor type distribution as a weighted sum of combinatorial terms, and we show that the latter converges to an explicit function. Next, we recover the previous results through pruning of the ancestral selection graph (ASG). The notions of relevant ASG, finite and asymptotic pruned lookdown ASG permit to achieve this task.

description: We consider the conformal blocks in the theories with extended conformal W-symmetry for the integer Virasoro central charges. We show that these blocks for the generalized twist fields on sphere can be computed exactly in terms of the free field theory on the covering Riemann surface, even for a non-abelian monodromy group. The generalized twist fields are identified with particular primary fields of the W-algebra, and we propose a straightforward way to compute their W-charges. We demonstrate how these exact conformal blocks can be effectively computed using the technique arisen from the gauge theory/CFT correspondence. We discuss also their direct relation with the isomonodromic tau-function for the quasipermutation monodromy data, which can be an encouraging step on the way of definition of generic conformal blocks for W-algebra using the isomonodromy/CFT correspondence.

description: This thesis analyzes the 2016 EU-Turkey Statement and, in particular, the ways in which externalization manifested as a primary means of coping with the Refugee Crisis. It then positions this response in context of the European Union’s historical approach toward migration policy beginning with the Barcelona Process in 1995. Specifically, I analyze the 2016 EU-Turkey Statement, the 1995 Barcelona Declaration, the 2005 Turkey National Action Plan for Adoption of the EU Acquis and subsequent 2006 Progress Report, as well as the Law on Foreigners and International Protection and its by-law the Temporary Protection Resolution.  It then considers the extent to which the externalization mechanisms found in the 2016 EU-Turkey Statement were either a singular response to a particular crisis, or a long-practiced mechanism in European Union migration governance.

description: The embryogenic calli were grown on MS medium containing NaCl with concentrations from 50 to 300 mM. After 2 weeks of culture, salinity tolerance threshold was identified at 150 mM NaCl. Higher concentrations of NaCl stimulated a significant reduction in the calli survival rate and the highest rate was 78.67% at 50 mM. After subculturing callus to the embryo culture medium con- taining NaCl, the growth and embryogenesis were not affected at the concentrations of 50 – 100 mM. Especially, at 50 mM NaCl the embryogenesis rate reached 83.33%. In contrast, 150 mM NaCl inhibited the somatic embryogenesis. After 4 weeks, culturing somatic embryos on medium MS with addition of 0.07 mg/l spermidin at 50 – 100 mM NaCl, the embryogenesis was considered good and embryos developed through several stages: globular, heart, torpedo and cotyledonary. However, at 150 mM NaCl the globular stage appeared in the culture process. The process of morphohistology and using dye carmine – iod and acridine orange observed the structure of generative callus and embryos at several stages.

Sau 2 tuần nuôi cấy, chúng tôi xác định được ngưỡng chịu mặn của mô sẹo có khả năng sinh phôi cây Cọc rào là 150 mM. Nồng độ muối NaCl càng cao thì tỷ lệ sống của mô sẹo giảm dần và đạt giá trị cao nhất là 78,67% tại nồng độ 50 mM NaCl. Khi chuyển mô sẹo sang môi trường phát sinh phôi có chứa muối NaCl với nồng độ thay đổi, chúng tôi thấy ở nồng độ muối NaCl 50 – 100 mM không ảnh hưởng đến khả năng sinh trưởng và phát sinh phôi, đặc biệt là tại nồng độ 50 mM NaCl giúp kích thích sự hình thành phôi từ mô sẹo với tỷ lệ hình thành phôi đạt 83,33%. Ngược lại, nồng độ từ 150 mM NaCl gây ức chế quá trình hình thành phôi soma từ mô sẹo. Tiếp tục khảo sát ảnh hưởng của muối đến khả năng phát triển và nảy mầm của phôi soma. Ghi nhận kết quả sau 4 tuần nuôi cấy phôi soma trong môi trường MS có bổ sung 0.07 mg/l spermidin, tại nồng độ 50 – 100 mM NaCl khả năng hình thành phôi tốt và phôi phát triển qua các giai đoạn phôi hình cầu, hình tim, hình thủy lôi và hình lá mầm. Đặc biệt ở nồng độ 50 mM số lượng phôi lá mầm đạt giá trị cao với 13,33 phôi. Nồng độ muối NaCl 150 mM chỉ xuất hiện phôi hình cầu trong suốt thời gian nuôi cấy. Quá trình giải phẫu hình thái phôi và sử dụng thuốc nhuộm 2 màu carmin – iod và acridine orange đã cho thấy rõ hơn về cấu trúc mô sẹo có khả năng sinh phôi và phôi hình thái.

Das gilt besonders für Schulleitungen, wo der Frauenanteil in den meisten Schulformen über 50 % beträgt. Dies hat sicherlich viele Gründe, zeigt aber auch, dass die vereinbarten Maßnahmen greifen und der angestrebte Wandel „in den Köpfen“ Realität geworden ist. Dennoch ist der Prozess noch nicht beendet: Auch wenn viele Frauen in Leitungspositionen angekommen sind, ist ihr Anteil in diesem Bereich niedriger als ihr Anteil an allen Stellen insgesamt. Gendergerechte Sprache, Vereinbarkeit von Beruf und Familie und der Umgang mit sexueller Belästigung am Arbeitsplatz sind Themen, die im Rahmen des Gleichstellungsgebots weiter verfolgt werden müssen.

description: Advanced driver assistance systems (ADAS) present promising benefits in mitigating road collisions. However, these benefits are limited when risky drivers continue engaging in distraction events. While there is evidence that real-time warnings help improve driving behaviour, the sustained benefits of warning-based ADAS on reducing driving distraction in light commercial vehicle (LCV) drivers remain unclear. This research determines the effect of receiving instant distraction warnings over two years using a naturalistic driving dataset comprising around one million trips from 373 LCV drivers in the Republic of Ireland. Furthermore, the study applies Association Rule Mining (ARM) to find the contextual variables (e.g., speed limit, road type, traffic conditions) that increase the likelihood of distraction events. The results show that warning-based ADAS providing real-time warnings helps reduce distraction events triggering driver inattention, forward collision, and lane departure warnings. Over half of the studied fleet reduced these warnings by at least 50% – lane departure after two months and driver inattention and forward collision after six months. It is found that both passive and active monitoring systems, coupled with coaching and rewards, significantly reduce aggressive driving behaviours tied to harsh acceleration (by 76%) and harsh braking (by 65%). The results of ARM show that the driving context introduces explanatory information for road safety programs. Low-speed urban roads and the summer season increase the likelihood of driver inattention and forward collision warnings. In contrast, high-speed rural roads increase the likelihood of lane departure warnings. These research findings support road safety stakeholders in developing risk assessments based on warning-based ADAS, targeted campaigns to reduce driving distraction, and driving coaching programs

description: Our theoretical study unfolds the topological phase transitions (within bands of the Moiré super-lattice) in small angle twisted double bilayer graphene (tDBLG) under the influence of external gate voltage and intrinsic spin-orbit coupling (SOC) for both AB-AB and AB-BA stacking configurations. Utilizing a low-energy continuum model, we investigate the band structure and perform a comprehensive topological characterization of the system by analysing the direct band gap closing as well as various Chern numbers. In the absence of SOC, the tDBLG exhibits characteristics of a valley Hall insulator. However, in the presence of SOC, we observe a transition to a quantum spin Hall insulator state and band topology emerges in the parameter spaces of non-topological regime without SOC. Furthermore, we conduct a comparative analysis between untwisted double bilayer graphene and tDBLG to assess the impact of twisting on the system's properties. Our findings reveal the construction of topological phase diagrams that showcase distinct phases arising from changes in the twist angle compared to the untwisted case. These phase diagrams provide valuable insights into the diverse topological phases achievable in tDBLG with SOC. Our findings contribute to the understanding of the interplay between small twist angle, SOC, and external electric field on the topological band properties of twisted multilayer graphene systems.

description: We present the results of the spectroscopic, photometric and orbital period variation analyses of the detached eclipsing binary \astrobj{V482~Per}. We derived the absolute parameters of the system (M$_{1}$ = 1.51 M$_{\odot}$, M$_{2}$ = 1.29 M$_{\odot}$, R$_{1}$ = 2.39 R$_{\odot}$, R$_{2}$ = 1.45 R$_{\odot}$, L$_{1}$ = 10.15 L$_{\odot}$, L$_{2}$ = 3.01 L$_{\odot}$) for the first time in literature, based on an analysis of our own photometric and spectroscopic observations. We confirm the nature of the variations observed in the system's orbital period, suggested to be periodic by earlier works. A light time effect due to a physically bound, star-sized companion (M$_{3}$ = 2.14 M$_{\odot}$) on a highly eccentric (e = 0.83) orbit, seems to be the most likely cause. We argue that the companion can not be a single star but another binary instead. We calculated the evolutionary states of the system's components, and we found that the primary is slightly evolving after the Main Sequence, while the less massive secondary lies well inside it.

description: We construct rotating boson stars and Myers-Perry black holes with scalar hair (MPBHsSH) as fully non-linear solutions of five dimensional Einstein gravity minimally coupled to a complex, massive scalar field. The MPBHsSH are, in general, regular on and outside the horizon, asymptotically flat, and possess angular momentum in a single rotation plane. They are supported by rotation and have no static limit. Such hairy BHs may be thought of as bound states of boson stars and singly spinning, vacuum MPBHs and inherit properties of both these building blocks. When the horizon area shrinks to zero, the solutions reduce to (in a single plane) rotating boson stars; but the extremal limit also yields a zero area horizon, as for singly spinning MPBHs. Similarly to the case of equal angular momenta, and in contrast to Kerr black holes with scalar hair, singly spinning MPBHsSH are disconnected from the vacuum black holes, due to a mass gap. We observe that for the general case, with two unequal angular momenta, the equilibrium condition for the existence of MPBHsSH is $w=m_1Ω_1+m_2Ω_2$, where $Ω_i$ are the horizon angular velocities in the two independent rotation planes and $w,m_i$, $i=1,2$, are the scalar field's frequency and azimuthal harmonic indices.

“I Did All This to Talk”: Picturing the Spiritual and Artistic Landscape of Joe Minter’s African Village in America
Creators: name: White, Tanner Reid
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: This thesis documents the phenomenon of Joe Minter’s African Village in America, a sprawling artistic creation that Mr. Minter employs as a vehicle for spreading the linked messages of the Gospel and the plight of African Americans. The African Village, in essence, becomes the stage through which Mr. Minter can physically engage the public in dialogue. Though Mr. Minter rejects the label of “preacher,” he nonetheless insists that he created the African Village to enable him to talk. This thesis thus treats Mr. Minter as much more than an artist; it presents him as an evangelist, an educator, and an activist. Additionally, it views the African Village not merely as another example of a yard art installation, but as a materialized sermon that Mr. Minter created with the assistance of the divine. For Mr. Minter, the African Village fulfills its purpose only when visitors come into the space, for only when they visit can Mr. Minter spread his—and God’s—message.

description: Lakes in Hanoi play an important role in local human life. However, along with the economic and social development, some urban lakes have been polluted, especially organic pollution. This paper presents the monthly survey results for organic pollution assessment of ten selected lakes in Ha Noi city: the Ho Tay, Truc Bach, Thien Quang, Ba Mau, Bay Mau, Hoan Kiem, Ngoc Khanh, Giang Vo, Thanh Cong and Thu Le lakes during the period from March 2014 to February 2015. The survey results showed that the Ba Mau lake was organic polluted at level IV whereas other lakes were contaminated by organic matters at level III. Organic pollution may come from both autochthonous and allochthonous sources. Compared with the results of previous studies, the water quality of 10 lakes in the period from March 2014 to February 2015 has been improved thank for the recent application of some positive solutions for lake environmental protection. Hệ thống hồ ở Hà Nội đóng vai trò quan trọng trong đời sống của người dân. Tuy nhiên, cùng với sự phát triển kinh tế xã hội, nhiều hồ trong nội đô đã và đang bị ô nhiễm, đặc biệt là ô nhiễm hữu cơ. Bài báo này trình bày kết quả khảo sát ô nhiễm hữu cơ tại 10 hồ trong thành phố Hà Nội: hồ Tây, Trúc Bạch, Thiền Quang, Ba Mẫu, Bảy Mẫu, Hoàn Kiếm, Ngọc Khánh, Giảng Võ, Thành Công và Thủ Lệ trong thời gian từ tháng 3 năm 2014 đến tháng 2 năm 2015. Kết quả khảo sát cho thấy hồ Ba Mẫu bị ô nhiễm hữu cơ ở mức IV, các hồ còn lại bị ô nhiễm hữu cơ ở mức III. Ô nhiễm hữu cơ tại các hồ có thể do cả hai nguồn cung cấp chất hữu cơ, ngoại lai và nội sinh. So với kết quả quan trắc trước đây, chất lượng nước 10 hồ Hà Nội đã được cải thiện do gần đây đã áp dụng một số biện pháp bảo vệ môi trường cho các hồ.

description: Many insects are considered as potential sources of food for humans because of their high content of protein, fat, minerals and vitamins. Tessaratoma papillosa Drury, a stink bug of longan tree has long been consumed by many people in Vietnam as a supplemental source of nutrition. This insect is one of the most severe pests of longan tree. The use of this insect as supplementary nutrient could actively reduce the pests on longans, contributing to increase productivity and quality of longan fruit. The aim of this paper is to estimate the volume of mature and young Tessaratoma papillosa on longan trees in Son La Province, Vietnam.

description: The interaction between nuclei and a strong zeptosecond laser pulse with coherent MeV photons is investigated theoretically. We provide a first semi-quantitative study of the quasiadiabatic regime where the photon absorption rate is comparable to the nuclear equilibration rate. In that regime, multiple photon absorption leads to the formation of a compound nucleus in the so-far unexplored regime of excitation energies several hundred MeV above the yrast line. The temporal dynamics of the process is investigated by means of a set of master equations that account for dipole absorption, stimulated dipole emission, neutron decay and induced fission in a chain of nuclei. That set is solved numerically by means of state-of-the-art matrix exponential methods also used in nuclear fuel burnup and radioactivity transport calculations. Our quantitative estimates predict the excitation path and range of nuclei reached by neutron decay and provide relevant information for the layout of future experiments.

description: The interaction of a free-electron-laser pulse with a moderate or large size cluster is known to create a quasi-neutral nanoplasma, which then expands on hydrodynamic timescale, i.e., $>1$ ps. To have a better understanding of ion and electron data from experiments derived from laser-irradiated clusters, one needs to simulate cluster dynamics on such long timescales for which the molecular dynamics approach becomes inefficient. We therefore propose a two-step Molecular Dynamics-Hydrodynamic scheme. In the first step we use molecular dynamics code to follow the dynamics of an irradiated cluster until all the photo-excitation and corresponding relaxation processes are finished and a nanoplasma, consisting of ground-state ions and thermalized electrons, is formed. In the second step we perform long-timescale propagation of this nanoplasma with a computationally efficient hydrodynamic approach. In the present paper we examine the feasibility of a hydrodynamic two-fluid approach to follow the expansion of spherically symmetric nanoplasma, without accounting for the impact ionization and three-body recombination processes at this stage. We compare our results with the corresponding molecular dynamics simulations. We show that all relevant information about the nanoplasma propagation can be extracted from hydrodynamic simulations at a significantly lower computational cost when compared to a molecular dynamics approach. Finally, we comment on the accuracy and limitations of our present model and discuss possible future developments of the two-step strategy.

description: Quang Ninh province, Vietnam has a rich wind power resources. This type of energy will be soon utilized for generating power to supply all industrial sites including mining corporations. Because of geological characteristics, wind power stations are located near the 6kV grid of mining areas, therefore it needs to make the analysis about the connection ability of wind power generators to the grids. The paper presents the connection model of a wind turbine and 6kV grids. Based on this model, the simulations of system’s possible operating mode are implemented. The conclusions about the suitable operating modes of wind turbine are pointed out to give the operators and grid managers a general observation for the possibility of connecting a wind turbine to 6kV grid. Tỉnh Quảng Ninh là một trong những địa phương giàu tiềm năng về năng lượng gió. Theo phân tích, loại năng lượng này sẽ sớm được đưa vào cung cấp điện năng cho các khu công nghiệp trong đó có các công ty than. Do đặc thù địa lý, các trạm phát phong năng được đặt khá gần các lưới điện 6kV của mỏ, vì thế cần tiến hành phân tích khả năng kết nối trực tiếp các máy phát điện gió với lưới điện này. Bài báo giới thiệu mô hình kết nối máy phát điện gió với lưới 6kV. Các mô phỏng về các chế độ vận hành có thể có của lưới cũng được thực hiện. Các kết luận về chế độ vận hành thích hợp của tua bin gió được đúc rút để giúp người vận hành, các nhà quản lý lưới điện có được cái nhìn tổng quan về khả năng kết nối tua bin gió với lưới điện 6kV.
