Optimal Quaternary Hermitian Linear Complementary Dual Codes for Entanglement-Assisted Quantum Error Correction

The objective of this thesis is to find suboptimal and optimal parameters from classical codes and import them into entanglement-assisted quantum codes. The thesis begins by introducing classical error correction, followed by a detailed introduction to quantum computing. Topics that are discussed in the introduction include qubits, quantum phenomena, such as superposition and entanglement, and quantum gates/circuits. The thesis then reviews the basics of quantum error correction and provides Shor's code to reinforce the reader's understanding. Subsequently, the formalism of stabilizer codes is thoroughly examined. We then explain the generalized concept of stabilizer codes which is entanglement-assisted quantum codes. They do not require generators to satisfy the commutativity property. Rather, they utilize the usage of ebits to resolve the anti-commutativity constraint. Next, the thesis explains quaternary field and then the Java program implemented to find the optimal parameters. Lastly, the thesis concludes with presenting the parameters of the new codes that were obtained throughout the research. We have found the suboptimal largest distance for quaternary hermitian linear complementary dual codes that can be imported as entanglement-assisted quantum error correction for parameters [22, 9, 9 or 10]₄, [22, 12, 7 or 8]₄, [23, 8, 11 or 12]₄, [23, 10, 9 or 10]₄, [23, 13, 7 or 8]₄, [24, 10, 10 or 11]₄, [24, 11, 9 or 10]₄, [24, 14, 7 or 8]₄, [25, 12, 9 or 10]₄, [25, 13, 8 or 9]₄, as well as the optimal largest distance for [17, 11, 5]₄ and [17, 13, 3]₄

EFEK LIKOPEN TERHADAP TIKUS PUTIH GALUR SD (Sprague Dawley) YANG DIINDUKSI PARASETAMOL DENGAN MELIHAT AKTIVITAS SGPT DALAM DARAH

Liver is one of the most important organ for drug metabolism in the body. Thedamage to the liver can be marked by increased activity of the enzyme alanineaminotransferase (ALT) in the blood. Lycopene is an antioxidant that has the ability toeliminate free radicals and detoxifies electrophilic compounds that damage can beprevented. The purpose of this research is to know whether lycopene can inhibit theincrease alanine aminotransferase activity of SD (Sprague Dawley) rats induced byparasetamol. This experiment using 20 male rats Sprague Dawley. They were dividedinto 4 groups. Group I is a healthy control (baseline) was only given aquadest, group IIwere given paracetamol as pain control, group III and IV are treatment group wereeach given lycopene with a dosage 15 µg/kg BW and 30 µg/kg BW for 21 days. On 19thday group II, as well as all treatment groups induced paracetamol. The blood samplingwas performed on orbital sinus on 19th day (before induced by paracetamol) and on 21thday or two days after induced paracetamol to know the difference alanineaminotransferase activity. The data were analyzed using non-parametric statisticalmethods with Kruskal-Wallis test followed by Mann-Whitney test with 95% confidencelevel. The result has showed that the lycopene doses 15 µg/kgBW had alanineaminotransferase activity of 130.10 ± 11.83 U/I and lycopene doses 30 µg/kgBW hadalanine aminotransferase activity of 106.46 ± 2.36 U/I. If compared with paracetamolcontrol had alanine aminotransferase activity of 92.53 ± 2.57 U/I, should take asummary that the lycopene doses 15 ìg/kg BW and 30 ìg/kg BW couldn’t decreasealanine aminotransferase activity on SD (Sprague Dawley) male rats

Petroleum Hydrocarbons Pollution o n the Sudanese Red Sea Coastal Water

The aim of this paper is to determine the extent of petroleum hydrocarbons pollution on the Sudanese Red Sea coast (Portsudan harbor and Bashayer Marine Terminal (BMT)), to achieve this goal laboratory work was conducted to determine hydrocarbons concentration. The highest concentration of Total Petroleum Hydrocarbons (TPH) in seawater was found at strip I (dockyard) with the average of 80.2 mg/l, the next to the highest concentration was generally occurred at strip IV (BMT), the ranges of concentrations were between 5.8 and 24.2 mg/l with mean value of 14.98 mg/l. Values of oil concentration at strip II (South port) are much lower than those of strip I (6.8 to 10 mg/l). Higher concentrations, ranging from nil to1320 mg/kg were detected in the sediment samples. It can be concluded on this basis that most of the Portsudan harbor and BMT suffers from oil pollution in different degrees according to UNEP and AIDMO. No oil contamination was observed at strip III (North port). The GC measurements proved those hydrocarbons contaminations were due to biologic and petrogenic origins, most oil samples light and middle fractions

Implementation of sustainability in the food and catering supply chains of UK HE institutions

Both organisations and customers are becoming more aware of the current economic, environmental and social challenges that the world faces today. In this context, it can be argued that universities are amongst the most important organisations that could contribute effectively in sustainability development in any society through producing and teaching sustainability related knowledge. This puts an ethical obligation upon these organisations to introduce and implement sustainability within their premises and operations. The procurement function is one of the main functions that can contribute effectively in the overall sustainability agenda of any university due to the large variety of products and services that this type of organisation procures and the related supply chain issues that they manage. However, the extant literature on Sustainability in Higher Education (SHE) suffers from a significant dearth of studies that specifically address Sustainable Procurement (SP) and Sustainable Supply Chain Management (SSCM) in universities. Thus, this thesis contributes to filling this particular gap through conducting exploratory research in order to investigate the implementation of SP initiatives in the current buying practices of UK based HE Institutions (Universities) and their supply chains, with a particular focus on the food and catering procurement area. This thesis, therefore, has two main overarching research questions, which are: “How are sustainability issues incorporated into the current food and catering procurement practices of UK based HE Institutions?” and “How are food and catering SP practices extended to multiple actors and multiple tiers across the existing supply chains of UK based HE Institutions?”. These two questions have been answered through three inter-related papers that tackle the following three topics: the implementation of SP initiatives through different implementation modes employed by universities (i.e., in-house catering vs outsourced catering); local sourcing as one of the main sustainability initiatives within universities’ sustainability agendas; and the impact of institutional pluralism on the implementation of sustainability initiatives within the university food and catering supply chain. The thesis uses three well-established theoretical lenses, (i.e., Transaction Cost Economics, Legitimacy Theory, and Institutional Theory), in the three papers respectively. Beside their own findings and contributions, the three papers collectively provide important contributions to both the SHE literature and the SSCM literature. In terms of the SHE literature, they: provide insights into the implementation of SP in HE institutions and their food supply chains; compensate for the dearth of studies on SSCM in HE; and enhance the theoretical authentication of the SHE literature. In terms of the SSCM literature, they: provide a new context for three theories; include a real supply chain perspective by including multiple tiers in the data collection and analysis; include the TBL in studying SSCM; and provided a theoretical generalisation of the results for the wider SSCM context

The Relationship Between Vocabulary Mastery and Reading Comprehension: An Assessment Prespective

In reading comprehension has some factors that influence the skill. One of the factors is vocabulary mastery. The objective of this research is to know whether there is any correlation between vocabulary mastery and reading comprehension and the degree of correlation. The total of the participants of this research was 30 students in VII A of the seventh grade students of SMPN 7 Metro. Cluster random sampling technique was used to get the sample. A correlatinal analysis was employed to know the relationship between scores in the reading comprehension and vocabulary mastery test. Based on the research calculation by using correlation product moment, it was obtained that  is 0,462, and  is 0,367 in significant 5% and 0,470 in significant 1%. The average of vocabulary mastery was 61,6. The finding also indicate that the students’ achievement in the vocabulary was poor. The average score of reading comprehension was 62,4. It means that the students’ achivement in the reading comprehension was fair. Therefore, the findings provide that there was a positive correlation between vocabuary mastery and reading comprehension of the seventh grade students of SMP N 7 Metro

Working with Latinos

For this article, our topic was “Working with Latinos/Hispanics”. We used social media, search engines such as google, worldly news, and other scholarly articles to research this topic. What we concluded was that many people had a stereotypical idea of what working with latinos was like. Many people don’t realize the cultural difference that America has in the workplace compared to other countries. As well as, the stereotyped idea of what jobs Latino/Hispanics work, how they carry out those jobs, and the struggles they face in those workplaces. In this paper we will discuss more, in detail, about what it means to work with latinos
