Published: October 2023

В представленій роботі розглянуто основні тенденції трансформації міграційних процесів та їх вплив на становлення та розвиток суспільних відносин. Так в ході дослідження доведно, що глобалізація розширює сферу міграційного впливу, залучаючи до цього явища все більше країн. Навіть країни, які раніше не були значними точками призначення або вихідними країнами міграції, тепер стають активними учасниками міграційних процесів. Це створює нові виклики та можливості для управління міграцією національними та міжнародними організаціями.
Також глобалізація має вплив на демографічну структуру країн, зокрема на зміну співвідношення між молодим та старим населенням, рівень народжуваності та смертності. Міграція може змінювати розмір та склад населення країни, що має важливі соціальні та економічні наслідки.
Основними методами дослідження є аналіз та синтез для представлення основних результатів дослідження, методи дедукції та індукції для виявлення основних трансформаційних процесів, що мають вплив на міграційні потоки.
Метою представленого дослідження є виявлення основних трансформаційних тенденцій, що мають місце в сучасних умовах глобалізації та пов’язані з міграційним процесом та його трансформацією.
Основними результатами дослідження можливо вважати наступне:
Обсяги міграції населення постійно зростають. Це пов'язано з різноманітними факторами, такими як геополітичні зміни, соціально-економічні нерівності, конфлікти та кризові ситуації. Зростає як міжнародна, так і внутрішня міграція в рамках країн.
Напрямки міграції також зазнають змін. Якісні зміни в економічному, політичному та соціальному контексті можуть призводити до зміни передпочитаних країн міграції. Такі зміни можуть бути викликані зміною ринкових умов праці, наявністю нових можливостей освіти та навчання, або наявністю соціальних зв'язків з певною країною.
Мігрантські групи стають все більш різноманітними за етнічною приналежністю, професійним складом, рівнем освіти та соціальним статусом. Це відображається в розмаїтості мотивацій та потреб мігрантів, а також впливає на їх інтеграцію в нові соціальні середовища.

Kecamatan Kedondong merupakan salah satu daerah yang berada di kabupaten Pesawaran yang memiliki luasan 67 km². Kecamatan Kedondong memiliki wilayah dengan sektor pertanian yang luas terdiri dari tanaman pangan dan hortikultura yang didonimasi oleh tanaman kakao. Selain itu, jumlah penduduk yang setiap tahun meningkat mengakibatkan terjadinya perubahan penggunaan lahan. Perubahan ini dapat mempengaruhi jumlah kawasan hijau di Kabupaten Pesawaran. Oleh karena itu perlu dilakukannya perhitungan perubahan lahan pada tahun 2002 hingga tahun 2020 dengan menggunakan citra landsat. Penelitian ini bertujuan untuk mengetahui perubahan tutupan lahan pada tahun 2002 hingga 2020 pada Kecamatan Kedondong. Penelitian ini menggunakan landsat 7 dan 8 yang diolah dalam metode Normalized Difference Vegetation Index (NDVI). Setelah dilakukannya pengolahan data kemudian dilakukannya pengamatan lapang terhadap 30 titik sampel yang telah diacak pada peta tahun 2020. Hasil analisis NDVI pada tahun 2020 terdapat peningkatan vegetasi kerapatan rendah (9,1%) dan sedang (27,9%) dari tahun 2002 hingga tahun 2020. Dan terjadi penurunan lahan terbuka sebesar 14,3%. Hal tersebut dikarenakan tanaman kakao sudah tumbuh besar dan juga terdapat banyak penambahan tanaman pepaya dan ubi kayu disela-sela tanaman kakao. Sehingga pola tanam tumpang sari mampu meningkatkan tutupan lahan. Hasil pengamatan lapang dan data hasil olahan menunjukan tingkat keakuratan sebesar 95%.
Kedondong subdistrict is one of the Pasewaran district areas, which has an area of 67 km². Kedondong subdistrict has an area with a large agricultural sector consisting of food and horticultural crops, which the cocoa plant dominates. In addition, the population that increases every year results in changes in land use. This change can affect the number of green areas in the Pasewaran District. Therefore, it is necessary to calculate land changes from 2002 to 2020 years using Landsat imagery. This study aims to determine changes in land cover from 2002 to 2020 in the Kedondong subdistrict. This study used Landsat 7 and 8, processed by the Normalized Difference Vegetation Index (NDVI) method. After data processing was carried out, field observations 30 randomized sample points on the map in 2020. The NDVI analysis results in 2020 showed an increase in the density of vegetation is low (9.1%) and moderate (27.9%) from 2002 to 2020 years. Moreover, there was a decrease in open land by 14,3%. This is because the cocoa plants had grown, and there are also many additions to papaya and cassava plants between the cacao plants. So that the intercropping cropping pattern can increase land cover. Infield observation has an accuracy level of 95%.

Published: October 2023

Penggunaan batubara sebagai sumber energi masih belum tergantikan hingga saat ini, sehingga kajian mengenai pemanfaatan abu batubara masih sangat perlu untuk dikembangkan. Abu batubara merupakan limbah hasil proses pembakaran batu bara yang komposisinya akan berbeda sesuai dengan jenis batubara yang digunakan dan proses pembakaran yang dilakukan. Salah satu komposisi penyusun utama dari abu batubara ini adalah silika. Silika memiliki potensi untuk dimanfaatkan dalam berbagai tujuan seperti untuk pengolahan limbah, untuk bahan aditif dalam pertanian, hingga sebagai nanosilika. Paper ini berisi informasi mengenai pemanfaatan silika dari abu batubara yang sudah ada serta metode yang efektif untuk mendapatkan silika dari limbah abu batu bara ini. Dari pembahasan diketahui bahwa studi pemanfaatan silika saat ini umumnya berfokus ke arah sintesis zeolite. Penelitian pemanfaatan silika sebagai nanosilika baru mulai dikembangkan baru-baru ini. Sementara itu, pemanfaatan silika tidak terlepas dari metode ekstraksi silika dari coal fly ash tersebut. Dari pembahasan diketahui NaOH masih menjadi pilihan utama dalam proses leaching silika. Studi ini diharapkan dapat memberikan informasi bagi kemajuan riset dalam rangkapengolahan dan pemanfaatan limbah.
The use of coal as an energy source has not been replaced until now, subsequently the studies on the utilization of coal fly ash still need to be developed. Coal fly ash is waste from the coal combustion process whose composition will differ according to the type of coal used and the combustion process carried out. One of the main constituents of coal ash is silica. Silica has the potential to be used in various purposes such as for waste treatment, for additives in agriculture, to nanosilica. This paper contains information on the utilization of silica from existing coal fly ash and an effective method for obtaining silica from the coal fly ash. Based on the discussion, it is known that the current study of the use of silica generally focuses on the synthesis of zeolite. The research on the use of silica as nanosilica has only recently been developed. Meanwhile, the role of silica is related to the method of extracting silica from the coal fly ash. It is known that NaOH is the main leaching solution in the case of silica leaching process. This study is expected to provide information for research progress in the context of processing and utilizing waste.

This study was designed to determine the geotechnical parameters and stability of soils in the Abbottabad region of Khyber-Pakhtunkhwa, Pakistan. The seven major sites with high population density were selected, covering the entire city, which includes Kalapul, Mandian, Jhangi, Nawanshehr, Cantonment, Abbottabad Courts and Jinnahabad. A total of thirty-two (32) boreholes were drilled to a depth of 5 m for standard penetration assessment and thirty two (32) field densification tests were performed at the designated sites. The standard penetration tests were carried out at every meter depth of the bore hole for recording penetration resistance, bearing potential and sample collection. Laboratory tests consisting of Grain-size analysis, Atterberg limits, California Bearing Ratio (CBR), Unconfined Compressive Strength (UCS), Direct Shear Box, and Proctor Compaction were conducted according to the ASTM standards on the accrued samples. The values of the performed tests were utilized for soils characterization and inspecting the Liquidity Index, Consistency Index, and Foundation evaluation for quite a number of footings. The results showed that most of the soils of the area belong to the Clay category (CL and A6 class) with excessive values of Plasticity Index (16.9%–18.6%), Liquidity Index (−47.33% to −23.07%) and Lower CBR (3%–6%), Angle of Internal Friction (15°–20°), UCS (79 kPa–121 kPa), Dry Density (15.13 kN/m3–17.66 kN/m3), Consistency Index (123.07%–147.33%) and Bearing Capacities, except the parts of Kalapul area, which belonged to the GP (poorly graded gravels) category with significant geotechnical properties. Based on the obtained results, we found that the land in the vicinity needs significant improvement before construction. For this purpose, various concentrations of limestone (12.5% and 25%), which is heavily mined in the area, were used as an additive. The results showed that the addition of limestone powder produced a significant improvement in all investigated properties and made the soft soil suitable for construction, in addition to any extended stabilization measures. The main reason for this improvement is the presence of more dense and lower water-absorbing minerals in the limestone than in the ground, or mineralization reactions between them.
Regulation of SPDEF expression by DNA methylation in advanced prostate cancer

Published: October 2023

IntroductionProstate cancer (PCa) presents a significant health challenge in men, with a substantial number of deaths attributed to metastatic castration resistant PCa (mCRPC). Moreover, African American men experience disproportionately high mortality rates due to PCa. This study delves into the pivotal role of SPDEF, a prostate specific Ets transcription factor, and its regulation by DNA methylation in the context of PCa progression.MethodsWe performed Epigenetic reprogramming using daily treatment with non-toxic dose of 5Aza-2-deoxycytidine (5Aza-dC) for two weeks to assess its impact on PDEF expression in prostate cancer cells. Next, we conducted functional studies on reprogrammed cells, including cell migration (wound-healing assay), invasion (Boyden-Chamber test), and proliferation (MTT assay) to comprehensively evaluate the consequences of altered PDEF expression. We used bisulfite sequencing (BSP) to examine DNA methylation at SPDEF promoter. Simultaneously, we utilized siRNA-mediated targeting of key DNMTs (DNMT1, DNMT3A, and DNMT3B) to elucidate their specific role in regulating PDEF. We measured mRNA and protein expressions using qRT-PCR and immune-blotting techniques, respectively.ResultsIn this report, we observed that: a) there is a gradual decrease in SPDEF expression with a concomitant increase in methylated CpG sites within the SPDEF gene during prostate cancer progression from lower to higher Gleason grade; b) Expression of DNMT’s (DNMT1, 3a and 3b) is increased during prostate cancer progression, and there is an inverse correlation between SPDEF and DNMT expression; c) SPDEF levels are decreased in RC77/T, a line of PCa cells from African American origin similar to PC3 and DU145 cells (CRPC cells), as compared to LNCaP cells , a line of androgen dependent cells,; d) the 5′ CpG island of SPDEF gene are hypermethylated in SPDEF-negative CRPC ( PC3, DU145 and RC77/T) cell lines but the same regions are hypomethylated in SPDEF-positive castrate sensitive (LNCaP) cell line ; (e) expression of SPDEF in PCa cells lacking SPDEF decreases cell migration and invasion, but has no significant effect on cell proliferation, and; (f) treatment with the demethylating agent, 5-aza-2′-deoxycytidine, or silencing of the DNMT’s by siRNA, partially restores SPDEF expression in SPDEF-negative PCa cell lines, and decreases cell migration and invasion.DiscussionThese results indicate hypermethylation is a prevalent mechanism for decreasing SPDEF expression during prostate cancer progression. The data demonstrate that loss of SPDEF expression in prostate cancer cells, a critical step in cellular plasticity, results from a potentially reversible process of aberrant DNA methylation. These studies suggest DMNT activity as a potential therapeutic vulnerability that can be exploited for limiting cellular plasticity, tumor progression, and therapy resistance in prostate cancer.
