In modern times, young people strive to become diplomats, economists, artists, lawyers, noble professions but irrelevant to the development of industry, technology and technology. The innovative development of the industry requires saturation with highly qualified technicians, continuously guided, educated and improved. The paper addresses the issues related to their personality, factors determining personal development, criteria for assessing personal development, technological culture, philosophy, basic qualities, attitude and skills necessary for the mining engineer, starting from the principle "Deep in the bowels of the Earth you find the root of knowledge!". The paper indicates, without being limiting, the authors' vision on how to approach the training of specialists for the exploitation of useful mineral substances (solids, liquids and gases).
Locimetric authentication is a form of graphical authentication where users validate their identity by selecting predetermined points on a predetermined image. Its primary advantage over the ubiquitous text-based approach stems from users' superior ability to remember visual information over textual information, coupled with the authentication process being transformed to one requiring recognition (instead of recall). Ideally, these differentiations enable users to create more complex passwords, which theoretically are more secure. Yet, locimetric authentication has one significant weakness, hot-spots, that is, areas in an image that users gravitate towards and consequently have a higher probability of being selected. This paper investigates whether the hot-spot problem persists with high-resolution images, as well as whether user characteristics and password length play a role. Our findings confirm the presence of hot-spots in high-resolution images, thus influencing the locimetric authentication scheme's effectiveness. Furthermore, we find that neither user characteristics (such as age, gender, and income) nor password length radically influence their extent. We conclude by proposing strategies to mitigate the hot-spot phenomenon.
Adaptive servoventilation (ASV) has been reported to show improvement in patients with sleep-disordered breathing (SDB) and heart failure (HF); however, its role as a second-line or adjunctive treatment is not clear. We conducted a systematic review and meta-analysis of new existing data including cardiac mechanistic factor, geometry, and cardiac biomarkers. We systematically searched for randomized controlled trials (RCTs) and cohort studies that assessed the efficacy or effectiveness of ASV compared to conventional treatments for SDB and HF in five research databases from their inception to November 2018. Random-effects meta-analyses using the inverse variance method and stratified by study design were performed. We included 15 RCTs (n = 859) and 5 cohorts (n = 162) that met our inclusion criteria. ASV significantly improved left ventricular ejection fraction (LVEF) in cohorts (MD 6.96%, 95% CI 2.58, 11.34, p = 0.002), but not in RCTs. Also, the ASV group had significantly lower apnea-hypopnea index (AHI) in both cohorts (MD − 26.02, 95% CI − 36.94, − 15.10, p < 0.00001) and RCTs (MD − 21.83, 95% CI − 28.17, − 15.49, p < 0.00001). ASV did not significantly decrease the E/e′ ratio in RCTs or in cohorts. Finally, ASV significantly decreased brain natriuretic peptide (BNP) in the cohorts (SMD − 121.99, CI 95% − 186.47, − 57.51, p = 0.0002) but not in RCTs. ASV did not have a significant effect on systolic blood pressure, diastolic blood pressure, and cardiac diameters. ASV therapy is associated with improvements of AHI in comparison to alternative treatments in patients with SDB and HF. ASV did not improve LVEF or E/e′ ratios in randomized trials; other intermediate outcomes did not improve significantly.
Proses pengelolaan air limbah di industry pertambangan sangatlah penting karena dapat mempengaruhi kelancaran proses penambangan. Air limbah yang tidak dapat dikeluarkan dari area bukaan tambang secara optimal dapat menghambat bahkan menghentikan aktivitas penambangan. Namun, jika air limbah tersebut dikeluarkan tanpa proses pengelolaan yang baik maka dapat berpotensi mencemari lingkungan sekitar dan juga melanggar aturan terkait nilai baku mutu air pada Pergub Sumsel No 8 Tahun 2012. Dampak dari pencemaran air adalah adanya sanksi administrasi hingga penyetopan produksi dari Pemerintah. Air limbah yang ada di Tambang PT Bara Anugrah Sejahtera memiliki karakteristik unik yaitu mengandung kadar silika yang tinggi. Hal ini menyebabkan partikel Total Suspended Solid (TSS) sulit untuk diendapkan secara normal. Hal ini terlihat pada kondisi air di big sump yang tetap konsisten kadar TSS di atas 5000 mg/liter walaupun terendap dalam periode yang cukup panjang. Berbagai jenis chemical telah dicoba untuk menurunkan kadar TSS namun belum ada yang dapat menurunkan TSS hingga baku mutu secara efektif dan efisien. PT Bara Anugrah Sejahtera melakukan inovasi dan berinvestasi dengan membangun fasilitas Waste Water Treatment Plant (WWTP) dalam mengelola air limbah agar dapat memenuhi baku mutu air secara efektif dan efisien. Mekanisme WWTP adalah memompa air limbah ke dalam labirin baffle untuk dicampurkan bersama chemical tertentu yang terdiri dari Koagulan dan Flokulan untuk mengikat antar partikel TSS menjadi bentuk gumpalan yang disebut Floc sehingga terpisah dari air secara stabil. Floc ini yang akan terendap pada saluran air terbuka sebelum settling pond yang kemudian akan dikuras menggunakan pompa lumpur ke mud pond terpisah agar siklus pengelolaan air tidak terhambat karena pendangkalan. Instalasi WWTP yang dikombinasikan dengan chemical tertentu yang terdiri dari Koagulan dan Flokulan terbukti dapat mengelola air limbah tambang berkadar silika tinggi di atas 780 mg/liter untuk memenuhi baku mutu air pada TSS <300 mg/liter tanpa mempengaruhi tingkat keasaman pada air.
