Data yang disimpan dalam sebuah dokumen memiliki tingkat keamanan yang sangat rentan, terlebih lagi jika dokumen tersebut tidak memiliki sistem keamanan untuk melindungi kerahasiaan dan keaslian dokumen tersebut. Salah satu cara untuk menjaga keamanan dan kerahasiaan dokumen adalah dengan menggunakan kriptografi. Kriptografi dikenal sebagai ilmu yang mempelajari teknik penyandian menggunakan matematika yang berkaitan dengan aspek keamanan informasi. Keamanan informasi yang dimaksud dapat berupa keabsahan data, kerahasiaan data, kredibilitas data, integritas data, dan autentikasi data. Dalam kriptografi terdapat algoritma-algoritma yang dapat digunakan untuk meningkatkan keamanan dokumen, salah satunya adalah algoritma Advanced Encryption Standard (AES). Advanced Encryption Standard adalah salah satu jenis kriptografi simetris dimana kunci yang digunakan untuk proses enkripsi dan dekripsi sama. Aplikasi enkripsi dekripsi yang dibuat berbasis desktop dengan harapan aplikasi ini dapat menjadi alternatif dalam membantu meningkatkan keamanan dokumen. Pada aplikasi yang dibuat dokumen yang dapat dienkripsi adalah dokumen-dokumen dengan format yang paling sering dijumpai yaitu dokumen dengan format .docx, dan .pdf.

Published: April 2024

Background
Endometriosis is a condition of the female reproductive system associated with pelvic pain. Chronic pain can affect physical performance by limiting the functional activities, thus, it is hypothesized that women with endometriosis may also present decreased functional capacity, decreased strength, and mobility. The objective of this study is to compare physical performance in women with and without endometriosis.

Methods
This is a cross-sectional study composed of 115 women equally divided into two groups: the endometriosis group (EG), composed of women with a confirmed diagnosis of the disease by magnetic resonance imaging, and the comparator group (CG), consisting of women without suspicion of the disease. Physical performance (dependent variable) was assessed using hand dynamometry, the 6-min walk test (6MWT), gait speed, and the chair stands test. CG participants performed the tests during the luteal phase of the menstrual cycle. Descriptive statistics, unpaired t-tests, and chi-square tests were used to describe and compare the groups. Multiple linear regression tested the associations adjusted for covariates (age, income, education, age at menarche, and body mass index).

Results
The EG had worse gait speed (mean difference: −0.11; 95% CI: [−0.18 to −0.04]), weaker grip strength (mean difference: −3.32; 95% CI: [−5.30 to −1.33]), shorter distance covered in the 6MWT (mean difference: −83.46; 95% CI: [−121.38 to −45.53]), and a lower number of repetitions in the chair stands test (mean difference: −8.44; 95% CI: [−10.64 to −6.25]) than the CG, even after adjusting for covariates.

Conclusion
Grip strength, lower limb strength, mobility, and functional capacity were worse in women diagnosed with endometriosis. Women with endometriosis should be encouraged to engage in physical exercise, adopt healthy lifestyle habits, and participate in rehabilitation activities to control pain, with the aim of reducing functional impairments.

A field study was conducted during Kharif 2019-20 at Professor Jayashankar Telangana State Agricultural University (PJTSAU), Rajendranagar, Hyderabad, Telangana, India to evaluate different handheld decision support tools for precision nitrogen management in rainfed maize (Zea mays L.). The study utilized a randomized block design and was replicated three times. The eight treatments included applying nitrogen through the State-recommended dose of 200 kg ha-1 in three splits (RDN), using a leaf color chart (LCC) based on N at thresholds 3 and 4, using a soil plant analysis development (SPAD) chlorophyll meter based on N at thresholds 35 and 40, and using a Green Seeker based on N at NDVI 0.6 and 0.8 in comparison with RDN and absolute control. Based on Green Seeker NDVI at threshold 0.8, the results showed that applying nitrogen resulted in considerably greater yields for maize grain (8408 kg ha-1), stover (9923 kg ha-1), and harvest index (45.8%). with higher yield and growth parameter viz., test weight (36.3 g ), No. of grain rows row-1 (36.7), cob length (18.9 cm), plant height (223.7 cm), leaf area (6385.75 cm2) and dry matter accumulation (18193 kg ha-1) as compared to RDN. Similarly, Green Seeker based N at NDVI 0.8 also registered higher net returns (Rs. 118961 ha-1) and B: C ratio (4.05).

Published: April 2024

Zusammenfassung
Krankenhäuser und Ärzte sehen sich mit einer erhöhten justiziellen Sensibilität ihrer Patienten für ihre Behandlungsmaßnahmen konfrontiert, die oftmals mit einer gerichtlichen Überprüfung des Falles einhergeht. Aufgrund der zunehmenden Spezialisierung vieler Kliniken, aber z.B. auch im Zusammenhang mit dem demografischen Wandel und der Vielzahl altersspezifischer Krankheiten sind dabei oft unterschiedliche Behandler in die streitgegenständliche Behandlung involviert. Geklagt wird dennoch oft nur gegen einen Behandler, obwohl es möglicherweise auf unterschiedlichen Ebenen zu Versäumnissen gekommen ist. In diesen Fällen bietet die Streitverkündung auf Beklagtenseite die Möglichkeit, Folgeansprüche zu sichern. Zudem ist die Streitverkündung auch von Anwaltsseite aus nicht zu vernachlässigen, da Fehler hier haftungsrelevant sind. Vor diesem Hintergrund ist es lohnenswert, sich die Besonderheiten der Streitverkündung im Arzthaftungsprozess genauer vor Augen zu führen.
Steuerberater und Wirtschaftsprüfer: Möglichkeiten der Haftungsbegrenzung in AGB – Enthaftung bis zum Vorsatz?
Authors: Gräfe Jürgen 
Published: April 2024

Zusammenfassung
Haftungsfreizeichnungen sind bei Verwendern von AGB‘s gegenüber Verbrauchern und Unternehmen beliebt. Die schärfste Freizeichnung ist die für vorsätzliches und grobfahrlässiges Handeln. Allerdings ist sie gem. § 309 Nr. 7b BGB untersagt. Das Verbot gilt nach h.M. auch im Handelsverkehr. In der Praxis werden in den Allgemeinen Auftragsbedingungen von Steuerberatern und Wirtschaftsprüfern häufig Klauseln verwendet, die den Anschein erwecken, als ob diese Gesetzeslage nicht zur Kenntnis genommen werden soll. Der folgende Beitrag erläutert das Verhältnis der gesetzlichen Grundlagen für die Haftungsbegrenzung von Angehörigen der rechts- und steuerberatenden Berufe in AGB und zeigt auf, aus welchen Gründen alle nur eine einheitliche Enthaftung für leicht fahrlässiges Verschulden vereinbaren und diese mit einer dem Auftragsinhalt und den Vermögensinteressen angemessenen Höchsthaftungssumme unterlegen sollten.

AbstractSeveral lines of evidence suggest an important role of the S100B protein and its coding gene in different neuropathological and psychiatric disorders like dementia, bipolar affective disorders and schizophrenia. To clarify whether a direct link exists between gene and gene product, that is, whether S100B variants directly modulate S100B serum concentration, 196 healthy individuals were assessed for S100B serum concentrations and genotyped for five potentially functional S100B SNPs. Functional variants of the serotonergic genes 5‐HT1A and 5‐HTT possibly modulating S100B serum levels were also studied. Further, publicly available human postmortem gene expression data were re‐analyzed to elucidate the impact of S100B, 5‐HT1A and 5‐HTT SNPs on frontal cortex S100B mRNA expression. Several S100B SNPs, particularly rs9722, and the S100B haplotype T‐G‐G‐A (including rs2186358‐rs11542311‐rs2300403‐rs9722) were associated with elevated S100B serum concentrations (Bonferroni corrected P < 0.05). Of these, rs11542311 was also associated with S100B mRNA expression directly (Bonferroni corrected P = 0.05) and within haplotype G‐A‐T‐C (rs11542311‐rs2839356‐rs9984765‐rs881827; P = 0.004), again with the G‐allele increasing S100B expression. Our results suggest an important role of S100B SNPs on S100B serum concentrations and S100B mRNA expression. It hereby links recent evidence for both, the impact of S100B gene variation on various neurological or psychiatric disorders like dementia, bipolar affective disorders and schizophrenia and the strong relation between S100B serum levels and these disorders. © 2009 Wiley‐Liss, Inc.

The genome‐centric concept: resynthesis of evolutionary theory
Authors: Heng Henry H. Q. 
Published: March 2009

AbstractModern biology has been heavily influenced by the gene‐centric concept. Paradoxically, this very concept – on which bioresearch is based – is challenged by the success of gene‐based research in terms of explaining evolutionary theory. To overcome this major roadblock, it is essential to establish new theories, to not only solve the key puzzles presented by the gene‐centric concept, but also to provide a conceptual framework that allows the field to grow. This paper discusses a number of paradoxes and illustrates how they can be addressed by the genome‐centric concept in order to further resynthesize evolutionary theory. In particular, methodological breakthroughs that analyze genome evolution are discussed. The multiple interactions among different levels of a complex system provide the key to understanding the relationship between self‐organization and natural selection. Darwinian natural selection applies to the biological level due to its unique genetic and heterogeneous features, but does not simply or directly apply to either the lower non‐living level or higher intellectual society level. At the complex bio‐system level, the genome context (the entire package of genes and their genomic physical relationship or genomic topology), not the individual genes, defines the system and serves as the principle selection platform for evolution.
A molecular thermodynamic approach to the prediction of phase equilibria in reservoir simulation
Authors: Lira‐Galeana Carlos , Ponce‐Ramirez Luis , Garcia‐Sanchez Fernando 
Published: March 2009

AbstractHighly asymmetric molecules interacting during miscible‐gas processes of oil recovery are responsible for the form of the reservoir fluid phase diagrams, from which feasible displacement conditions can be chosen. In order to fit the expermental fluid phase behavior, current reservoir models employ classical equations of state which cannot easily account for the polydisperse and asymmetric nature of such systems.Using a continuous thermodynamics extension of the Simplified Perturbed Hard‐Chain Theory (SPHCT) equation of state of Kim et al. (1986), an alternative molecular method for representing these equilibria in reservoir‐fluid systems is presented. The approach yields results which compare well with both experimental data and classical calculation procedures.
Distinctions between low density and high density circulating fluidized beds
Authors: Zhu J.‐X. , Bi H.‐T. 
Published: March 2009

AbstractWhile many fundamental studies have been carried out in relatively low density circulating fluidized beds (LDCFB), there has been little reported fundamental study of the high density (including high solids flux and/or high solids concentration) circulating fluidized bed (HDCFB), although many commercial CFB setups are operating under high density conditions. Catalytic gas‐phase reactions tend to require higher gas velocity and higher solids flux and/or concentration than gas‐solids reactions, and therefore it is necessary to make a distinction between the two types of operations. The study of hydrodynamics and other fundamentals of HDCFB will help in understanding the fundamentals and thus improving the design and operation of existing HDCFB reactors such as FCC risers, and may also lead to other applications requiring even higher solids/gas feed ratios and/or higher solids concentration in the riser. On the other hand, high density operation can only be achieved by properly choosing the gas blower, solids feeding system and CFB geometry to avoid the instabilities resulting from insufficient pressure head from the gas blower and downcomers.
Effects of pressure and temperature on flow regimes in gas—Solid fluidization systems
Authors: Bi H. T. , Grace J. R. 
Published: March 2009

AbstractThe effects of operating temperature and pressure on the flow regimes of gas—solids fluidization are predicted based on the recently published flow regime diagram of Bi and Grace (1995b). The predictions are consistent with the evidence available in the literature. At constant superficial gas velocity, increasing system pressure and decreasing system temperature shift the behaviour toward higher velocity flow regimes. The opposite trends are realized if, instead, the gas mass flowrate is held constant.
The mean flow field generated by a pitched blade turbine: Changes in the circulation pattern due to impeller geometry
Authors: Mao De‐Ming , Feng Lian‐Fang , Wang Kai , Li Yu‐Ling 
Published: March 2009

AbstractThe mean flow field in a tank stirred with a pitched blade turbine was measured using a two‐component Laser Doppler Anemometer system (LDA). The effects of impeller clearances and impeller geometries (number of blades, blade angle and blade size) on the mean flow field have been studied. The primary pumping number, induced pumping number of the primary circulation loop and the induced pumping number of the secondary circulation loop, which often has been ignored, are reported. The flow patterns and circulation loops are more complex than those traditional ones, which vary with the geometries of the PTD and the clearances.
Measurement of the local intensities of segregation with the tomographical dual wavelength photometry
Authors: Buchmann Mathias , Mewes Dieter 
Published: March 2009

AbstractThe newly developed tomographical dual wavelength photometry enables the measurement of the local intensity of segregation at a multitude of points inside the stirred vessel. This is done by injecting a mixture of an inert and a reacting dye into the vessel. The inert dye serves as a tracer for the macromixing, whereas the vanishing of the reacting dye shows the micromixing. The concentration fields of the dyes are measured simultaneously by transluminating the vessel from three directions with superimposed laser beams of different wavelength. The light absorption by the dyes is measured with CCD‐cameras and these projections are used for the tomographic reconstruction of the concentration fields. Low Reynolds number measurements with a Rushton turbine show better macro‐ and micromixing for a dye injection closer to the stirrer shaft compared to a position closer to the main vortex.
Tuning digital PI controllers for minimal variance in manipulated input moves applied to imbalanced systems with delay
Authors: Kelly Jeffrey Dean 
Published: March 2009

AbstractDetermining the discrete‐time proportional plus integral (PI) controller tuning parameters to achieve the smallest possible variance in the manipulated input moves, for a given variance in the controlled output, is the subject of this article. Previous researchers have developed tuning rules for PI and PI permutated nonlinear controllers to achieve what is commonly referred to as “level‐flow smoothing”, or “averaging level control”, on imbalanced or integrating processes with delay, such as liquid level and gas pressure systems. The intent of this note is to demonstrate a new and simple technique of tuning digital PI controllers which utilizes either open or closed‐loop historical data to estimate the process gain, dead‐time and expected flow disturbance magnitude from which the digital PI tuning constants can be easily derived. By parameterizing the closed‐loop system as a function of the PI tuning constants, we can simultaneously minimize the expected variation in the process input move and output responses while at the same time ensuring nominal stability of the overall system. In order to demonstrate the technique, an illustrative example is included which highlights the new procedure on an oil refinery liquid surge drum level process.

AbstractAdsorption equilibrium constants of ethanol, methanol, isobutylene, isoamylenes (2M2B, 2M1B), MTBE and TAME on Amberlyst 15 catalyst were evaluated from the packed bed moment technique. Adsorption equilibrium constants of alcohols were found to be two orders of magnitude greater than the adsorption equilibrium constants of i‐olefins and the corresponding tertiary ethers. However, their apparent heat of adsorption values are quite low (‐6,7 kJ/mol and −8.3 kJ/mol for methanol and ethanol, respectively). Among the i‐olefins, isobutylene gave the highest adsorption equilibrium constant and the heat of adsorption (‐54.2 kJ/mol The adsorption equilibrium constant of 2M2B on a catalyst, which was pretreated with ethanol, was about three times greater than the corresponding value obtained on fresh catalyst. Second moment analysis indicated that diffusion resistance in both macropores and microspheres of the catalyst are equally significant.
