Keberagaman Jenjang Kelas Untuk Meningkatkan Efisiensi Tempat, Hasil Dan Aktivitas Belajar Di Sekolah Indonesia Den Haag (SIDH) Belanda

Field: Social Sciences (Social Sciences)

Teaching and learning activities have standardization in accordance with the Regulation of the Minister of National Education of the Republic of Indonesia Number 24 of 2007 concerning Standard for Facilities and Infrastructure. In fact, the limited facilities and teaching staff are owned by the Sekolah Indonesia Den Haag (SIDH) so that it can affect the teaching and learning process for students. The purpose of this study was to determine the steps taken by the Sekolah Indonesia Den Haag (SIDH) in increasing student learning activities by combining small and large elementary class levels. The research method used is descriptive qualitative. The subjects of this study were the teaching staff and students of the Sekolah Indonesia Den Haag (SIDH) Elementary School with a total of nine regular level students. Combining class levels is a step to improve student learning outcomes and activities by looking at the limitations of class fitness, teaching staff, and students. Finally, the authors conclude that based on the above discussion, there has been a success. In other words, combining class levels in the grouping of small SD and large SD can improve the results and activities of students in classrooms with limited class space.
[Results of 52 operations for traumatic cataracts].

Field: Medicine (Health Sciences)

The authors are presenting the results of the traumatic cataract surgery in 52 patients (45 male, 7 female). The cataract was caused in 7 cases by blunt trauma, in 43 cases by penetrating trauma (in 16 cases with intraocular foreign body). The mean age of patients was 29 years, ranging from 4 to 73 years. In 2 cases was indicated the intracapsular extraction for the subluxation of the lens, in 2 eyes the discision was done and in 2 eyes the primary evacuation. In all other cases the extracapsular extraction was performed (19 with IOL implantation). Before the operation the visual acuity was 0.1 and worse in 90.4%, 0.16-0.33 in 7.7% and 0.5 and better in 1.9% of the patients. The visual acuity at the time of the last follow-up visit (3 months to 3.5 years after the operation-average 15.6 months) was 0.1 and worse in 16.7% of cases, 0.16-0.33 in 19% and 0.5 and better in 64.3%. The visual acuity 0.5 and better was in 85.7% of patients with IOL implantation. The most serious complication was the hypotony of the eye (in 3 cases) followed by the atrophy of the eye (1 eye was enucleated). Although we could expect more complications of the surgery of traumatic cataract it is possible to gain good visual acuity results. The IOL implantation is indicated in cases where it is not excluded by the condition of the eye.

Toxin production ability of Bacillus cereus strains from food product of Ukraine

Field: Immunology and Microbiology (Life Sciences)

Potential pathogens of foodborne toxic infections – bacterial contaminants Bacillus cereus isolated from plant raw materials and food products from the Ukrainian region were investigated. When determining of the proportion of isolated bacilli from the plant samples, it was established that the epidemiologically significant microorganisms of Bacillus cereus as agents of food poisoning are the second largest. The average value of contaminated samples of Ukrainian plant raw materials and processed products with Bacillus cereus is 36,2 %. The ability of Bacillus cereus strains identified by a complex of morphological, tinctorial, cultural and biochemical properties, to produce specific emetic and enterotoxins was studied. Molecular genetic diagnosis and detection of the toxin-producing ability of isolated 42 Bacillus cereus strains showed both the possibility of their rapid identification and the presence of specific toxicity genes. Multiplex polymerase chain reaction (PCR) was carried out with specific primers to detect toxicity determined of various bacilli genes: nheA, hblD, cytK, cesВ. The distribution of toxigenic genes is significantly different among the Bacillus cereus isolates from various sources. The nheA, hblD and cytK enterotoxin genes were detected in 100, 83,3 and 61,9 % of the investigated strains of Bacillus cereus, respectively. The cesB gene encoding emetic toxin was detected in 4,8 % of strains. Molecular-genetic PCR-method confirmed that all the isolated strains belong to the Bacillus cereus group, and the ability to produce toxins can be attributed to five groups. The main toxins that produce the investigated Bacillus cereus strains were nhe and hbl enterotoxins encoded by the corresponding genes of nheA and hblD. The enterotoxic type of Bacillus cereus was predominant in Ukrainian region. Studies of domestic plant food raw materials and products have confirmed the need to improve microbiological control of product safety by introducing accelerated specific diagnostics of contaminants by molecular genetics methods.

Weld Repair of C, Cr-Mo Cokedrums (and Pressure Vessels) Without PWHT

Field: Engineering (Physical Sciences)

Many of the Cr{1-1/4 to 2-1/4}-Mo{1/2 to 1} pressure vessels in the refining and petrochemical industries such as process reactors, distillation columns, separators, pressurized storage vessels, and heat exchangers are typically vertical columns, most often supported by a circular skirt. Typically, design considerations for these vessels and support skirts are for operating under continuous “steady-state” conditions, where temporary stresses due to short-term “transient” events such as start-up and shutdown are often ignored. Consequences of dynamic and cyclic loading play a very significant role in their life and performance. For Coke drums, survey data from API shows that the skirt-to-drum attachment weld and adjoining area appears to be the most problematic, frequently experiencing low-cycle fatigue cracking due to concentrated stresses. A methodology for repairing the skirt attachment weld of Cr-Mo pressure vessels is provided. When designing a repair approach, consideration should include material and aged condition, extent and location of defects, welding process and consumables, and codes, standards, and regulatory guidelines. When repair by weld metal buildup to rebuild a skirt-attachment weld configuration is considered, weld procedure qualification and adequate mock-ups should be performed in order to ensure a sound repair. Further, when invoking a code compliant repair without post-weld heat treatment by controlled deposition welding or temper bead techniques, proper training of welder operators should be conducted to ensure the techniques are implemented properly. A case study is provided for a Coke drum, where the original design and fabrication of the skirt attachment included an initial SAW weld metal buildup on the 2.25Cr (P5A) cone followed by an SMAW/GTAW attachment weld to the 1.25Cr skirt (P4). During a plant shutdown, a surface breaking crack was detected in the skirt to shell attachment weld by Dye Liquid Penetrant Testing (D-LPT) and confirmed with Magnetic Particle Testing (MPT). Subsequent examination by Phased Array Ultrasonic Testing (PAUT) discovered a large number of volumetric indications, oriented towards the knuckle section internally. The repair approach consisted of 1) Completely remove the existing skirt and the attachment weld (knuckle) in segments, 2) Inspect the cone for remaining flaws, 3) Excavate and repair flaws in cone using temper bead technique, 4) Rebuild knuckle area for skirt to cone attachment with an increased radius using temper bead welding techniques, 5) Install new skirt sections using controlled deposition welding technique. Temper Bead and Controlled Deposition repair welding techniques were utilized to avoid conventional post-weld heat treatment requirements, significantly improving the turn-around time in the field.
Rapid identification of single nucleotide polymorphisms by fluorescence-based capillary electrophoresis

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

We describe the application of two different fluorescence-based techniques (ddNTP primer extension and single-strand conformation polymorphism (SSCP)) to the detection of single nucleotide polymorphisms (SNPs) by capillary electrophoresis.The ddNTP primer extension technique is based on the extension, in the presence of fluorescence-labeled dideoxy nucleotides (ddNTP, terminators), of an unlabeled oligonucleotide primer that binds to the complementary template immediately adjacent to the mutant nucleotide position.Given that there are no unlabeled dNTPs, a single ddNTP is added to its 3' end, resulting in a fluorescence-labeled primer extension product which is readily separated by capillary electrophoresis.On the other hand, the non-radioisotopic version of SSCP established in this study uses fluorescent dye to label the PCR products, which are also analyzed by capillary electrophoresis.These procedures were used to identify a well-defined SNP in exon 7 of the human p53 gene in DNA samples isolated from two human cell lines (CEM and THP-1 cells).The results revealed a heterozygous single-base transition (G to A) at nucleotide position 14071 in CEM cells, proving that both fluorescence-based ddNTP primer extension and SSCP are rapid, simple, robust, specific and with no ambiguity in interpretation for the detection of well-defined SNPs.
Detecting Privacy Preferences from Online Social Footprints: A Literature Review

Field: Computer Science (Physical Sciences)

Providing personalized content can be of great value to both users and vendors. However, effective personalization hinges on collecting large amounts of personal data about users. With the exponential growth of activities in social networking websites, they have become a prominent platform to gather and analyze such information. Even though there exist a considerable number of social media users with publicly available data, previous studies have revealed a dichotomy between privacy-related intentions and behaviours. Users often face difficulties specifying privacy policies that are consistent with their actual privacy concerns and attitudes, and simply follow the default permissive privacy setting. Therefore, despite the availability of data, it is imperative to develop and employ algorithms to automatically predict users’ privacy preferences for personalization purposes. In this document, we review prior studies that tackle this challenging task and make use of users’ online social footprints to discover their desired privacy settings.
A Comparison of White and Indian Student Attitudes Toward the Negro

Field: Social Sciences (Social Sciences)

It is important for students of race prejudice to know the attitudes of various racial groups towards other racial groups. Ideally, comparisons should be made between the attitudes of each group toward itself and toward each other group in the experiment, but this is not always feasible because of the lack of satisfactory techniques for study, or because comparable groups of subjects are not satisfactorily represented in any available population. For this last reason it is often impossible to determine the attitudes of various racial groups toward only one race, while the lack of comparable scales for measuring attitudes of each group toward each other group prevent satisfactory comparisons even where the problem of selection of subjects is not so formidable. The study reported here cannot claim to have overcome either of these difficulties, although a beginning in inter-race attitude studies has been made. Where the larger Indian boarding schools are found it is sometimes possible to make Indian and white comparisons, but even in such cases it is rarely possible to obtain a large group of Negroes of the same age and school background for comparison. In the present study of attitude toward the Negro data are available on more than one hundred Indian and more than one hundred white students in Lawrence, Kansas, but on only a few Negroes. The data were collected in 1934, the subjects being 105 students from Haskell Institute who were studying Problems in American Government, and 110 white students from the Lawrence High School who were taking Problems in Civil Government. The attitudes of the thirteen Negro high school students taking the same course as the white students were also obtained.' All students were in the same school grade and of very similar age. The Indian students came from various regions of the country; the other two groups were residents of the community and natives of a small territory in the Middle West. The Thurstone scale for measuring Attitude Toward the Negro was employed for the study. The statements composing the scale and their numerical values are as follows:
Molecular-scale substrate anisotropy and crowding drive long-range nematic order of cell monolayers

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

The ability of cells to reorganize in response to external stimuli is important in areas ranging from morphogenesis to tissue engineering. Elongated cells can co-align due to steric effects, forming states with local order. We show that molecular-scale substrate anisotropy can direct cell organization, resulting in the emergence of nematic order on tissue scales. To quantitatively examine the disorder-order transition, we developed a high-throughput imaging platform to analyze velocity and orientational correlations for several thousand cells over days. The establishment of global, seemingly long-ranged order is facilitated by enhanced cell division along the substrate's nematic axis, and associated extensile stresses that restructure the cells' actomyosin networks. Our work, which connects to a class of systems known as active dry nematics, provides a new understanding of the dynamics of cellular remodeling and organization in weakly interacting cell collectives. This enables data-driven discovery of cell-cell interactions and points to strategies for tissue engineering.
Marketing energy conservation options to Northwest manufactured home buyers

Field: Energy (Physical Sciences)

This study relies on extensive, existing survey data and new analyses to develop information that would help design a marketing plan to achieve energy conservation in new manufactured homes. Existing surveys present comprehensive information about regional manufactured home occupants and their homes that are relevant to a potential conservation marketing plan. An independent analysis of the cost-effectiveness of various efficiency improvements provides background information for designing a marketing plan. This analysis focuses on the economic impacts of alternative energy conservation options as perceived by the home owner. Identifying impediments to conservation investments is also very important in designing a marketing plan. A recent report suggests that financial constraints and the need for better information and knowledge about conservation pose the major conservation investment barriers. Since loan interest rates for new manufactured homes typically exceed site-built rates by a considerable amount and the buyers tend to have lower incomes, the economics of manufactured home conservation investments are likely to significantly influence their viability. Conservation information and its presentation directly influences the manufactured home buyer's decision. A marketing plan should address these impediments and their implications very clearly. Dealers express a belief that consumer satisfaction is the major advantage to selling energy efficient manufactured homes. This suggests that targeting dealers in a marketing plan and providing them direct information on consumers' indicated attitudes may be important. 74 refs.
Derivation of Stochastic Partial Differential Equations for Reaction-Diffusion Processes

Field: Mathematics (Physical Sciences)

Stochastic partial differential equations are derived for the reaction-diffusion process in one, two, and three dimensions. Specifically, stochastic partial differential equations are derived for the random dynamics of particles that are reacting and diffusing in a medium. In the derivation, a discrete stochastic reaction-diffusion equation is first constructed from basic principles, that is, from the changes that occur in a small time interval. As the time interval goes to zero, the discrete stochastic model leads to a system of It stochastic differential equation. As the spatial intervals approach zero, a stochastic partial differential equation is derived for the reaction-diffusion process. The stochastic reaction-diffusion equation can be solved computationally using numerical methods for systems of It stochastic differential equations. Comparisons between numerical solutions of stochastic reaction-diffusion equations and independently formulated Monte Carlo calculations support the accuracy of the derivations.
Avoiding the Landau-pole in perturbative QCD

Field: Physics and Astronomy (Physical Sciences)

We propose an alternative perturbative expansion for QCD. All scheme and scale dependence is reduced to one free parameter. Fixing this parameter with a fastest apparent convergence criterion gives sensible results in the whole energy region. We apply the expansion to the calculation of the zero flavor triple gluon vertex, the quark gluon vertex, the gluon propagator and the ghost propagator. A qualitative agreement with the corresponding lattice results is found.
PERFORMANCE OF CONCRETE WITH MINERAL ADMIXTURES UNDER CARBONATION EXPOSURE: AN EXPERIMENTAL APPROACH

Field: Engineering (Physical Sciences)

This study investigates the effects of carbonation on the durability and performance of concrete incorporating various mineral admixtures. Mineral admixtures such as fly ash, rice husk ash, ground granulated blast furnace slag (GGBS), and silica fume were used as partial replacements for cement to enhance sustainability and modify the microstructure of the concrete matrix. A series of concrete mixes were prepared with different proportions of these admixtures and subjected to accelerated carbonation conditions. The influence of carbonation on compressive strength, pH variation, and depth of carbonation was systematically analyzed. Results indicated that the inclusion of mineral admixtures influenced the rate of carbonation and the residual strength of concrete, depending on their chemical composition and pozzolanic activity. The study highlights the trade-off between enhanced durability and carbonation susceptibility in modified concrete and provides insights into the optimal use of mineral admixtures for long-term performance in CO₂-rich environments. The incorporation of mineral admixtures significantly enhanced the mechanical properties of concrete compared to conventional mixes. This study investigates the influence of mineral admixtures—Fly Ash (FA) and Rice Husk Ash (RHA)—on the compressive strength of concrete and its enhancement under controlled CO₂ exposure. A total of sixteen concrete mixes were prepared, incorporating varying percentages of FA and RHA, both individually and in combination. The compressive strength was evaluated before and after 40 hours of CO₂ exposure to assess the effect of accelerated carbonation. The control mix exhibited a strength of 34.56 N/mm², which increased to 42.12 N/mm² upon CO₂ exposure. Notably, the mix with 20% FA showed a strength improvement from 39.40 N/mm² to 46.49 N/mm², while the mix with 20% RHA achieved the highest strength enhancement, rising from 42.64 N/mm² to 48.25 N/mm². Dual replacement mixes, such as 10% FA + 30% RHA and 30% FA + 20% RHA, also showed improved strength performance after carbonation. The results demonstrate that both FA and RHA are effective in enhancing concrete strength, particularly under CO₂ curing conditions. Furthermore, the utilization of these industrial and agricultural by-products contributes to environmental sustainability by reducing cement usage and minimizing waste disposal. This study supports the use of dual mineral admixtures in concrete production as a viable strategy for improving performance and addressing ecological concerns.
Krull Dimension and Reflexivity in some Noetherian Rings

Field: Mathematics (Physical Sciences)

In this paper we study Noetherian prime rings R which satisfy the formula \R\ = sup{|/**//|:/ is an essential left ideal of R} + 2, where | | denotes left Rrull dimension.If further Q/R is \R\ -1 unmixed, where Q is the simple Artinian quotient ring of R, we characterize R using torsion theories cogenerated by the injective hulls of |Ä| -1 dimensional critical modules.Also equivalent statements are established, linking homological properties with dimension theory, for Ä-modules to be reflexive.A similar result holds for right submodules.Identifying /* with /"' we have Ici** and /* = I***.Further / is reflexive if and only if / = I**.All rings have a 1 and all modules are unital.Unless otherwise specified, all properties are left properties.A regular ideal is a left ideal with a regular element.The Krull dimension is denoted by I I. _
