AN ANALYSIS OF STUDENTS’ ABILITY IN USING AUXILIARY VERB AT MTSN 1 BENGKALIS

ABSTRAK T.M Arkan Faisal (2022): Analisis Kemampuan Siswa dalam Menggunakan Kata Kerja Bantu di MTsN 1 Bengkalis Penguasaan siswa dalam menggunakan kata kerja bantu sangatlah penting. Unsur Bahasa inggris ini diperlukan untuk menunjang kemampuan Bahasa inggris. penelitian ini bertujuan untuk mengetahui kemampuan siswa dalam menggunakan kata kerja bantu dalam present perfect tense di kelas tiga MTsN 1 Bengkalis. Penelitian ini dilaksanakan pada bulan Maret saampai dengan bulan Mei 2022. Penelitian ini menggunakan penelitian deskriptif kuantitatif. Populasi dalam penelitian ini adalah siswa kelas tiga MTsN 1 Bengkalis dengan jumlah sampel 25% dari populasi. Untuk mengambil sampel, peneliti menggunakan teknik simple random sampling. Dalam mengumpulkan data, peneliti membagikan tes. Tes tersebut terdiri dari 30 soal, soal tersebut menunjukkan kemampuan menggunakan kata kerja bantu pada present perfect tense. Setelah dilakukan analisis data, terlihat bawa kemampuan siswa dalam menggunakan kata kerja bantu termasuk dalam kategori kurang dengan nilai rata-rata 55,2. Persentase masing-masing kategori sebagai berikut: tidak ada siswa pada kategori sangat baik, 15 (26,0%) siswa pada kategori baik, 19 (33,0%) siswa pada kategori cukup, 14 (25,0%) siswa pada kategori kurang, kemudian ada 8 (14,0%) siswa pada kategori gagal

Rancang Bangun Aplikasi Game Puzzle Berbasis Android Menggunakan Algoritma Decision Tree

The development of games today is very rapid and has become part of the lifestyle. A puzzle game is an application that can be used to hone thinking and memory skills where users have to find a way out and collect special items that have been provided at every level of the game . The player must collect all the white orb in each level to get the key to move to the next level but the player will be confronted by the constraints on how to find the key and retrieve it . The game is designed using decision tree and game algorithms designed using Game Maker Studio that is applied to Android devices

Status of 3.9 GHz superconducting RF cavity technology at Fermilab

Fermilab is involved in an effort to assemble 3.9 GHz superconducting RF cavities into a four cavity cryomodule for use at the DESY TTF/FLASH facility as a third harmonic structure. The design gradient of the cavities is 14 MV/m. This effort involves design, fabrication, intermediate testing, assembly, and eventual delivery of the cryomodule. We report on all facets of this enterprise from design through future plans. Included will be test results of single 9-cell cavities, lessons learned, and current status

Field quality of quadrupole R&D models for the LHC IR

Superconducting quadrupole magnets operating in superfluid helium at 1.9 K, with 70 mm bore and nominal field gradient of 205 T/m at collision optics, are being developed by the US LHC Accelerator Project for the Interaction Regions of the Large Hadron Collider (LHC). A magnet model program to validate and optimize the design is underway. This paper reports results of field quality measurements of four model magnets. (3 refs)

Quench performance of Fermilab high gradient quadrupole short models for the LHC Interaction Regions

Fermilab and LBNL are in the midst of superconducting magnet R&D program to test and optimize the design of quadrupoles to be used in the LHC Interaction Region inner triplets. The magnets are required to deliver a 215 T/m gradient across a 70 mm aperture. Five quadrupole short models have been fabricated and four of them have been tested. This paper describes the last model design details and reports the results of the magnet quench performance study. (5 refs)

IKKβ regulates essential functions of the vascular endothelium through kinase-dependent and -independent pathways

Vascular endothelium provides a selective barrier between the blood and tissues, participates in wound healing and angiogenesis, and regulates tissue recruitment of inflammatory cells. Nuclear factor (NF)-κB transcription factors are pivotal regulators of survival and inflammation, and have been suggested as potential therapeutic targets in cancer and inflammatory diseases. Here we show that mice lacking IKKβ, the primary kinase mediating NF-κB activation, are smaller than littermates and born at less than the expected Mendelian frequency in association with hypotrophic and hypovascular placentae. IKKβ-deleted endothelium manifests increased vascular permeability and reduced migration. Surprisingly, we find that these defects result from loss of kinase-independent effects of IKKβ on activation of the serine-threonine kinase, Akt. Together, these data demonstrate essential roles for IKKβ in regulating endothelial permeability and migration, as well as an unanticipated connection between IKKβ and Akt signalling
