Application of pulverized-coal fuel (PCF) for coke saving is strategic direction of energy costs decreasing for iron smelting in PAO NLMK blast furnaces, which allows to change the structure of coals supply to the plant and to decrease their summarized consumption. Stages of the technology mastering considered, including period of adjusting the PCF preparation and their supplying to the blast furnaces and at the stage of charging system selection and blast regime adjustment ensuring the maximum degree of CO utilization and the specified performance. Analysis of the dynamics of coke consumption and fuel additives showed that the consumption of total carbon fuel remained almost unchanged, despite the difference in the amount of carbon supplied with natural gas and with the PCF. Calculations made by the mathematical model showed that with an increase in the PCF consumption and a decrease in the consumption of natural gas, the replacement rate of coke with natural gas increased by an average of 0.09 kg of coke per 1 cubic meter of natural gas. As a result of the iron smelting technology mastering, in the PAO NLMK BF № 2 a specific coke consumption decrease reached by more than 80 kg/t of iron and natural gas consumption decrease by more than 60 m3/t of iron. The conditions were revealed for the blast furnaces to operate as with minimum coke consumption and with maximum intensity. The blast furnaces operation in the determined regime parameters allow to decrease the fuel costs for iron production.

During the high hardness grinding balls production the following to the process parameters is the key requirement. The temperature and the deformation uniformity are main parameters at the high hardness grinding balls rolling. Reduction forces can be estimated by modeling, but in this case, they were determined analytically, based on the distribution of the real specific reduction force over the observed temperature fields on the surface of the ball. Revealed a significant increase in the temperature of ball during the cross-helical rolling from equator to the poles from 880 °С to 940 °С. Established temperature increase (up to 60 °C) was observed in the area of the roll flange penetration into the workpiece, where significant deformations occur. Maximum average power of rolling generated on the top of the roll flanges has been determined, which reaches 350 MPa and decreases linearly with the distance from the top of the flange of the deformation tool and is practically reduced to zero on the equator of the ball. It was shown that linear nature of the change of the specific power of rolling is in good agreement with the linear dependence of the mill roll flange growth when it is introduced into the workpiece.

ABSTRACTThe collapse of Minnesota Bridge number 9340 or I-35W bridge on August 1, 2007, is indeed surprising considering the maintenance of the bridge conducted regularly. The bridge was designed in the early 1960s using AASHO "Standard Specification for Highway Bridges" 1961 edition with the allowable stress method. Materials used HSLA (high-strength low-alloy) steel. The data on the I-35W bridge obtained from the NTSB (National Transportation Safety Board) report. The analysis to identify the cause of the collapse of the I-35W bridge derived from the results of a review of previous research.The method of analysis referred to is a simple method of Holt and Hartman (2008), FEM by Hao (2010), Liao (2010), and Lora (2013).The finding of the I-35W bridge indicates that the cause is due to the lack of U10 gusset plate capacity, because the thickness of the gusset plate at the joint is the other thinnest gusset plate and its failure due to buckling, and the condition of the gusset plate has been deformation in the construction period. The further adds a substantial buckling.The result of evaluation using simple and FEM method proves that the gusset plate capacity of the U10 joint is inadequate so that the gusset plate overstressed. The collapse pattern of the gusset plate at the U10 joint has similarities between the analysis with FEM and the damage of the real bridge.Keyword: Steel truss bridge, joint, gusset plateABSTRAKKeruntuhan jembatan Minnesota no. 9340 atau jembatan I-35W pada 1 Agustus 2007 sangat mengejutkan mengingat perawatan jembatan ini dilakukan teratur secara berkala. Jembatan ini didesain pada awal tahun 1960an menggunakan peraturan AASHO “Standard Specification for Highway Bridges” edisi 1961 dengan metode tegangan ijin. Material yang digunakan baja mutu tinggi HSLA (high-strength low-alloy). Data-data mengenai jembatan I-35W diperoleh dari laporan NTSB (National Transportation Safety Board). Sedangkan analisis untuk mengidentifikasi penyebab keruntuhan jembatan I-35W diperoleh dari hasil kajian dari penelitian terdahulu. Metode analisis yang diacu adalah metode sederhana dari Holt dan Hartman (2008), metode FEM oleh Hao (2010), Liao (2010), dan Lora (2013).Hasil analisis terhadap keruntuhan jembatan I-35W menunjukkan bahwa penyebab keruntuhan disebabkan kapasitas pelat buhul U10 yang kurang karena ketebalan pelat buhul pada sambungan tersebut paling tipis dibanding pelat buhul yang lain dan keruntuhannya akibat tegangan tekuk yang besar, serta kondisi pelat buhul sudah mengalami deformasi pada saat masa pengkonstruksian. Hal ini makin menambah tekuk yang besar.Hasil evaluasi dengan metode sederhana maupun FEM membuktikan bahwa kapasitas pelat buhul pada sambungan U10 tidak memadai sehingga pelat buhul mengalami overstress. Pola keruntuhan pelat buhul pada sambungan U10 mempunyai kesamaan antara analisis dengan FEM dengan kerusakan jembatan aslinya.Kata Kunci: Jembatan rangka baja, sambungan, pelat buhul

ABSTRACTReclaimed Asphalt Pavement (RAP) material as a result of road maintenance by Scrapping-Filling-Overlay method is a waste material which had potential to be recovered as a surface layerof road. The maintenance in highway road of Indonesia used hot mix asphalt in general. But, hot mix asphalt are not environmentally friendly and makes energy wasting because it needs burning process at mixing. Those things are the main causes of this research. This asphalt concrete with RAP with cold mixing is expected to fulfill the requirements of asphalt concrete for heavy traffic. In this research is asphalt content variations at 6,5; 7,0; 7,5; 8,0; and 8,5% to total mixture. The results of this research shows that the highest Marshall stability could not reach minimum value of heavy loaded traffic, that is at emulsion asphalt content 7% only for 711 kg. Besides, the percentage of void in mixture (VIM), void filled with bitumen (VFB) and flow couldn’t fulfill the specification of SNI 8198:2015. With the result that optimum asphalt content cannot be obtained. Result of wheel tracking test could not be obtained too because the specimens collapse during the test.Key words : Emulsion asphalt, Reclaimed Asphalt Pavement, stability, Wheel Tracking MachineABSTRAKMaterial Reclaimed Asphalt Pavement (RAP) hasil dari pemeliharaan dengan metode Scrapping-Filling Overlay merupakan limbah yang berpotensi untuk dimanfaatkan kembali menjadi lapis permukaan.

The study results of lung volume seasonal changes in skiers of mass categories in the conditions of European North are presented. Respiratory system study was carried out in September, January, April and July in the same group of 38 men skiers aged 18-22 (middle age: 19,6 (19,2; 21,7)), born and permanently residing in Arkhangelsk (64°32'n.l., 40°32'e.l.) and Severodvinsk (64°34'n.l., 39°51'e.l.). Survey sample had experience in cross-country skiing for 3-5 years and 1-2 senior degree. Spirograph «Dinamit-С» (Complex КМ-АР-01) was used for pulmonary function test. Lung volume was esteemed: respiratory volume (RV), inspiratory (IRV) and expiratory (ERV) reserve volume, inspiratoty capacity (IC), lung capacity (LC), as well as indices of lung ventilation: respiratory rate (RR) and respiratory minute volume (RMV). It is stated that skiers have seasonal functional alternation in the external respiration system. Thus, LC maximum was in winter, LC minimum - in spring, with difference 1,21 l. RV minimum was in summer, maximum - in winter, with difference 0,58 l. IRV was maximum in autumn, ERV and IC - in winter. Not only statistic lung volumes indices, but their nature of communication change in seasonal dynamic in surveyed sportsmen skiers. Percentage ratio calculation from RV to LC showed that breathing in rest conditions skiers use from 17 % in autumn and summer to 21-23,5 % LC in winter and spring. Comparison of the results obtained in skiers and people not engaged in sport activities revealed that seasonal changes of lung volume in skiers are more evident.

Perpustakaan sekolah merupakan salah satu sumber belajar mengajar yang penting dalam proses pembelajaran di tingkat sekolah. Keberadaan jasa layanan  perpustakaan sekolah dibutuhkan untuk memenuhi kebutuhan informasi bagi seluruh sivitas akademik di sekolah.  Penelitian ini bertujuan untuk mengetahui kepuasan pemustaka terhadap kualitas layanan perpustakaan di Pondok Pesantren Asshiddiqiyah Jakarta Barat. Metode yang digunakan dalam penelitian ini adalah LibQual+TM yaitu suatu metode untuk mengukur kualitas layanan perpustakaan berdasarkan empat dimensi yaitu Affect of Service (kemampuan dan sikap pustakawan dalam melayani pengguna), Library as Place (perpustakaan sebagai sebuah tempat), Personal Control (petunjuk dan sarana akses), dan Information Access (akses informasi). Hasil penelitian ini menunjukkan secara umum kualitas layanan perpustakaan memuaskan dengan Adequacy Gap menunjukan hasil positif yaitu 1.7 yang berarti pemustaka cukup puas dengan layanan yang diberikan perpustakaan. Dan hasil Superiority Gap menunjukan hasil negatif yaitu -1.2 yang berarti kualitas layanan yang diberikan perpustakaan dalam batas toleransi. Sedangkan untuk evaluasi layanan koleksi kitab Islam, keberagaman koleksi memerlukan perhatian khusus, karena sekitar 79% responden menganggap jika perpustakan Asshiddiqiyah kurang memiliki keberagaman koleksi.

Wakaf merupakan salah satu instrumen penting yang menopang kemajuan ekonomi umat Islam. Uang sendiri belum banyak diketahui dan diterima masyarakat sebagai salah satu instrumen dalam wakaf. Padahal wakaf uang memiliki potensi yang luar biasa, khususnya bagi Indonesia sebagai negara dengan jumlah penduduk muslim terbesar di dunia. Penelitian ini bertujuan untuk memberikan gambaran pelaksanaan wakaf uang di Indonesia, mengidentifikasi permasalahan yang terjadi, serta memberikan solusi alternatif dari permasalahan tersebut dari sudut kepustakawanan. Penelitian ini merupakan penelitian deskriptif yang dilakukan dengan studi literatur. Penelitian ini menunjukkan bahwa wakaf uang di Indonesia masih jauh dari potensi yang ada. Permasalahan ini terjadi antara lain karena masih minimnya literasi hukum wakaf uang di masyarakat. Untuk mengatasi hal tersebut, salah satu solusi alternatif yang dapat dilakukan adalah dengan melakukan kemas ulang informasi hukum wakaf uang.Kata kunci: Kemas ulang informasi; Literasi hukum; Wakaf uang.
ANALISIS PELAKSANAAN MIGRASI SISTEM OTOMASI DI PERPUSTAKAAN KEMENTERIAN KOMUNIKASI DAN INFORMATIKA RI

Migrasi sistem otomasi merupakan suatu hal yang penting untuk dilakukan oleh perpustakaan ketika sistem otomasi yang lama dirasa sudah tidak lagi bisa mendukung kegiatan operasional perpustakaan. Tujuan dari penelitian adalah untuk menjelaskan tentang pelaksanaan migrasi sistem otomasi Perpustakaan Kementerian Kominfo RI. Penelitian ini menggunakan pendekatan kualitatif dengan metode penelitian studi kasus. Subjek dari penelitian adalah pustakawan dan kepala perpustakaan Kemkominfo dan objek penelitian ini adalah pelaksanaan migrasi sistem otomasi di perpustakan Kemkominfo. Hasil penelitian menunjukan bahwa migrasi sistem otomasi di Perpustakaan Kemkominfo RI dilakukan dengan cara menginput ulang data koleksi buku yang sebelumnya sudah ada pada sistem otomasi yang pertama kali digunakan, yakni Sistem Pustaka ke sistem yang baru, SLiMS. Terdapat beberapa faktor penting yang mempengaruhi pelaksanaan migrasi sistem otomasi tersebut, yakni dalam hal kepemimpinan, komunikasi, pelatihan, dan perencanaan. Di perpustakaan Kemkominfo, ke-empat faktor tersebut tidak berjalan dengan baik sehingga hal tersebut menjadi hambatan bagi perpustakaan Kemkominfo dalam melakukan migrasi sistem otomasi. Selain itu, pelaksanaan migrasi sistem otomasi ini, memberikan dampak yang kurang baik terhadap layanan sirkulasi di Perpustakaan Kemkominfo. Oleh sebab itu, pihak perpustakaan Kemkominfo sebaiknya perlu untuk membuat perencanaan yang lebih baik, secara tertulis, terkait pelaksanaan migrasi sistem otomasi perpustakaan agar pelaksanaan migrasi sistem otomasi dapat terselesaikan dengan cepat dan tepat sehingga dapat meningkatkan kualitas layanan perpustakaan.Kata kunci: Sistem Otomasi, Migrasi sistem otomasi, Perpustakaan Kemkominfo, Sistem Pustaka, SLiMS

Oxidative stress markers are usually measured in plasma, a stable environment for biomarkers. Blood collection is invasive, but the use of alternative biofluids is limited, due to high variability. In this study, we aimed to establish reference values for oxidative stress markers in plasma, urine and saliva of adult, healthy mice and to identify some sources of variability. Samples were obtained from 41 female and 37 male adult, healthy mice of the CD-1 strain, aged 95-480 days, weighing 21-55 grams. Reference ranges of TBARS (thiobarbituric acid reactive substances), AOPP (advanced oxidation protein products), fructosamine, GSH/GSSG (reduced and oxidized glutathione) ratio, TAC (total antioxidant capacity), and FRAP (ferric reducing antioxidant power) were measured in plasma and urine, and TBARS, GSH/GSSG ratio, TAC and FRAP in saliva, using standard spectrophotometric and fluorometric methods. Salivary GSH/GSSG and urinary AOPP were higher in females. Urinary fructosamine, GSH/GSSG and FRAP were higher in males. Urinary TAC and FRAP negatively correlated with age, and urinary GSH/GSSG positively correlated with weight. We determined that urine and saliva can be obtained non-invasively from mice, in sufficient amounts for reliable oxidative status assessment. Further studies are needed to uncover whether these biofluids reflect systemic oxidative status in diseases.

Prenatal exposure to caffeine can cause developmental problems. This study determined chronic influence of prenatal caffeine at relatively higher doses on cognitive functions in the rat offspring. Pregnant Sprague-Dawley rats (4-month-old) were exposed to caffeine (20 mg/kg, twice a day) for whole pregnancy from gestational day 4. Fetal and offspring body and brain weight was measured. Learning and memory were tested in adult offspring with Morris water maze. Learning and memory-related receptors were measured. The exposure to prenatal caffeine not only caused fetal growth restriction, but also showed long-term effects on learning and memory in the offspring. The caffeine offspring exhibited longer escape latency and path length in navigation testing. The number of passing the target was significantly reduced in those offspring. The expression of adenosine A1 and A2A receptors, nuclear PKA Cα, Cβ subunits, and pCREB were significantly increased in the fetal and neonatal brain, and suppressed in the hippocampus of the adult offspring. The expression of BDNF and TrkB were reduced regardless of various ages. The results suggest that intrauterine programming dysfunction of adenosine receptors and the down-stream of cAMP/PKA/pCREB system may play an important role in prenatal caffeine induced cognition disorders in the adult offspring.

The geometry of the distal anastomosis of a femoropopliteal bypass influences local hemodynamics and formation of intimal hyperplasia. We hypothesized that the distal anastomosis of an above-knee femoropopliteal bypass undergoes remodeling that results in displacement of the original course of the popliteal artery and change in the anastomosis angle. We identified 43 CT angiography examination with proximal femoropopliteal bypass and either a preserved contralateral popliteal artery or previous CTA before construction of the bypass for comparison. In these examinations, we measured the displacement distance and angle at the level of the distal anastomosis and compared these measurements with clinical and imaging data. The displacement distance was 8.8±4.9 mm (P<0.0001) and the displacement angle was -1° (IQR=44°). The angle between the inflow and outflow artery was 153±16° (P<0.0001). There was a negative association between the displacement angle and the angle between the bypass and the outflow artery (r=-0.318, P=0.037). Patients with reversed venous grafts had a greater displacement of the anastomosis (14.7±3.0 mm) than patients with prosthetic grafts (8.0±4.5 mm, P=0.0011). We conclude that construction of a distal anastomosis of proximal femoropopliteal bypass results in displacement of the original course of the popliteal artery towards the bypass and this effect is more pronounced in reversed venous grafts.
