Published: December 2019

History shows the development of human thinking patterns that are more advanced in understanding, utilizing and further knowing the causes and results of the findings obtained. Humans find strong material, with complex phenomena and unknown compilation yet, but they have felt of great benefit. And with the development of knowledge, conventional and modern processes are carried out to achieve the goal. Namely with the methods carried out, managing the metal has a different impact than before, then the metals change physically and non-physically. This study aims to learn more about the relationship of metals treatment to hardness and the vibration that occurs in metal material that is disputed. This research uses experimental methods on materials with treatment and un-treatment to study the correlation, which is supported by the method of testing the hardness test and vibration test. The results show that increased strain on hardness and vibration patterns of metal have full or correlated. In this study, un-load raw materials was obtained an average hardness value of 52.28 HRB with an average vibration of 1.448 mm / s. While the specimen with tensile load obtained an average hardness of 52.34 HRB with an average vibration pattern of 1.7388 mm / s. These results show an increase in hardness of 0.115% and vibration of 20.028%, which is an increase in stretching effect. It can be concluded, however that increasing strain loads increase the hardness and vibration of low carbon steel equivalent ST-37.

Authors: Tokur Bozkurt Yüksel , Taşpınar Necmi
Published: December 2019

The progression in technology
requires improved modulation techniques for wideband digital communication
systems. Orthogonal frequency division multiplexing is efficacious systems to
fulfill high-speed data transmissions needs. However, high peak-to-average
power ratio (PAPR) is one of the significant limitations on the performance and
power efficiency of OFDM systems. Due to industrial and scientific relevance,
the assessment of the PAPR reduction has become popular subject in the current
decade. This study presents the combination of bat algorithm with partial
transmit sequence scheme as an efficient PAPR reduction method with an
alleviated computational load. A set of simulations with different partial
transmit sequence schemes are performed to comparatively evaluate the PAPR
reduction performance of the partial transmit sequence based on bat algorithm
scheme in OFDM system. The simulation results elucidate that BA-PTS scheme can
provides better PAPR reduction performance with less computational load.

Published: December 2019

Constant-impedance, constant-current and constant-power ZIP models of electrical loads are commonly used in smart grid and residential load applications. Some of residential loads are of nonlinear nature such as LCD monitors and computers. In this study, first, equivalent ZIP model formulas of parallel-connected electrical loads are derived. Then, the ZIP models of an LCD monitor, a computer case and the computer case and the monitor connected in parallel have been obtained using experimental data and least-squares curve fitting method. Finally, the equivalent ZIP model formulas are tested with the experimental data. It has been found that for the rectifier nonlinear loads with different ZIP parameters, the formulas do not give acceptable errors. Therefore, for rectifier nonlinear loads, the measurement-based approach for load modeling must be performed.

Published: December 2019

The article discusses the methodology and technical solution of recycling fish farm waste using closed-water supply systems by means of a basin method, which ensures their use as a source of liquid fertilizer and the production of separate substrates for aqua- and hydroponics. Since currently applied systems for the purification of wastewater in closed water supply systems do not provide for the second-time use of waste in the form of solid particles and mineral components. It is worth noting that the present scientific work is regarded as a relevant technical solution. This technology is highly environmentally friendly and does not require waste disposal, as well as it helps to increase yield. In addition, as a biologically closed cycle, the waste recycling system will significantly reduce water consumption and create complex biological clean systems, as well as improve working conditions at minimal costs and reduce the service personnel through automation.

Jaw tumors are odontogenic and non-odontogenic. In all these types of tumors, the main treatment method is surgical treatment. Operations of the lower jaw are accompanied by severe cosmetic disorders and facial deformity. Surgery on the the lower jaw consists not only in the radical removal of the tumor, but also in the simultaneous restoration of the continuity of the mandibular arch to prevent possible functional and cosmetic disorders. In this case, the surgeon should solve two different tasks – to remove the tumorcompletely and close the defect as much as possible. The use of simultaneous plastic allows to obtain good functional and cosmetic results for various methods of reconstruction of the lower jaw. This, in turn, allows some patients to return to work, which they did before the onset of the disease. To prevent complications in various methods of reconstructive surgery on tumors of the lower jaw, the effect of radiation therapy and the localization of the tumor on the lower jaw should be taken into account.

AGROEKOLOGI : MODEL PERTANIAN BERKELANJUTAN MASA DEPAN
Authors: Yulianto Kiki
Published: December 2019

Indonesia sebagai negara kepulauan yang terletak di daerah khatulistiwa termasuk wilayah yang sangat rentan terhadap perubahan iklim. Perubahan pola curah hujan, kenaikan muka air laut, dan suhu udara, serta peningkatan kejadian iklim ekstrim berupa banjir dan kekeringan merupakan beberapa dampak serius perubahan iklim yang dihadapi Indonesia.

Perubahan iklim akan menyebabkan: (a) seluruh wilayah Indonesia mengalami kenaikan suhu udara, dengan laju yang lebih rendah dibanding wilayah subtropis; (b) wilayah selatan Indonesia mengalami penurunan curah hujan, sedangkan wilayah utara akan mengalami peningkatan curah hujan. Perubahan pola hujan tersebut menyebabkan berubahnya awal dan panjang musim hujan. Di wilayah Indonesia bagian selatan, musim hujan yang makin pendek akan menyulitkan upaya meningkatkan indeks pertanaman (IP) apabila tidak tersedia varietas yang berumur lebih pendek dan tanpa rehabilitasi jaringanirigasi. Meningkatnya hujan pada musim hujan menyebabkan tingginya frekuensi kejadian banjir, sedangkan menurunnya hujan pada musim kemarau akan meningkatkan risiko kekekeringan. Sebaliknya, di wilayah Indonesia bagian utara, meningkatnya hujan pada musim hujan akan meningkatkan peluang indeks penanaman, namun kondisi lahan tidak sebaik di Jawa. Trend perubahan ini tentunya sangat berkaitan dengan sektor pertanian.

KARESIDENAN MANADO DALAM KANCAH PERDAGANGAN MARITIM DI HINDIA BELANDA, AWAL ABAD XIX – 1942
Authors: Purba Jhon Rivel
Published: December 2019

Penelitian ini mengkaji keterlibatan Karesidenan Menado dalam perdagangan maritim di Hindia Belanda pada abad XIX sampai 1942. Rumusan pertanyaan yang dijawab dalam penelitian ini yaitu, apakah letak geografis Karesidenen Menado turut memengaruhi keterlibatannya dalam jaringan perdagangan maritim di Hindia Belanda? dan bagaimana dinamika perdagangannya di bawah pemerintahan Hindia Belanda? Penulisan ini menggunakan metode kualitatif (studi pustaka). Hasil penelitian memperlihatkan bahwa keterlibatan karesidenan ini dalam perdagangan maritim tidak hanya didukung oleh potensi ekonomi, tetapi juga oleh letak geografisnya yang relatif memudahkan pelaku ekonomi untuk memasuki wilayah ini. Karesidenan Menado dikelilingi beberapa perairan yang bersentuhan langsung dengan beberapa kawasan, seperti Filipina di sebelah utara, Ternate di sebelah timur, Jepang di sebelah timur laut, dan pesisir barat wilayah Amerika. Selain Pemerintah Kolonial Hindia Belanda, KPM dan Cekumij-nya, aktor yang berperan dalam kegiatan ini yaitu penduduk lokal, Etnis Tionghoa, Orang Arab, dan negaranegara lain, seperti Inggris, Jepang, Jerman, Perancis, Norwegia, dan Amerika Serikat, melalui kapal-kapalnya. Potensi ekonomi dan keberadaan kapal asing mendorong pemerintah membuat sejumlah regulasi, yaitu pengangkutan komoditas perdagangan harus menggunakan kapal KPM atau Cekumij. Pemerintah juga mengalihkan rute distribusi komoditas tersebut ke Makassar. Kapal milik negara lain tidak lagi dapat menjemput komoditas secara langsung ke daerah penghasil, tetapi harus mengambilnya ke Makassar.
PERLAWANAN SAWITTO TERHADAP BELANDA DI SULAWESI SELATAN PADA 1905-1906
Authors: Amir Muhammad
Published: December 2019

Kajian ini mengungkap dan menjelaskan perlawanan Kerajaan Sawitto terhadap pemerintah Hindia Belanda pada tahun 1905-1906. Metode penelitian yang digunakan adalah metode sejarah, yang menjelaskan suatu persoalan berdasarkan perspektif sejarah. Prosedurnya terdiri atas heuristik, kritik sumber, interpretasi, dan historiografi dalam bentuk kisah. Hasil kajian menunjukkan bahwa perlawanan Kerajaan Sawitto terhadap pemerintah Hindia Belanda, bukan hanya dilatari oleh kepentingan ekonomi yang berkaitan kebijakan pelabuhan wajib pajak, melainkan juga kepentingan politik yang berkaitan dengan campur tangan pemerintah Belanda terhadap urusan dalam negeri Kerajaan Sawitto, bahkan ingin menguasai Sawitto secara langsung. Hal tersebut ditandai dengan diajukannya suatu tuntutan terhadap Kerajaan Sawitto agar tunduk, taat, dan patuh sepenuhnya kepada pemerintah Belanda dengan menandatangani pernyataan pendek (korte verklaring). Karena menolak tuntutan itu, pemerintah Belanda memutuskan untuk melancarkan serangan militer terhadap Kerajaan Sawitto, namun serangan tersebut mendapat perlawanan dari laskar Sawitto di bawah pimpinan La Sinrang. Pada akhirnya, pasukan Belanda berhasil mengalahkan laskar Sawitto.

Kegiatan nelayan setelah melaut adalah melakukan kegiatan rutin, seperti membenahi peralatan tangkap dan menjual hasil tangkapannya di pinggir pantai atau koperasi TPI. Diversifikasi usaha untuk membantu keadaan ekonomi nelayan, memberikan peran anggota keluarga untuk ikut berpartisipasi atau pola nafkah ganda, dan jaringan sosial dimanfaatkan untuk memberi ruang ekonomi agar dapat bertahan, seperti kegiatan utang piutang melalui peran modal sosial yang telah tertanam pada masyarakat Desa Sumare.
TARSKY DISTRICT AND HIS EMPLOYEES IN THE FIRST THIRD OF THE XVIII CENTURY
Authors: Puzanov V. D.
Published: December 2019

The article examines the situation of Tara uyezd and service people who lived in the town of Tara in the first third of the 18th century. The research relies on such archival materials as responses of officials of Tara uyezd who completed to Prof. G.F. Miller’s questionnaire, books and tables of Siberian prikaz on the servitors in Siberia, and materials from the Senate fund. The article provides data on the town of Tara and Tara uyezd in the 1730s. Tara had a near-border position. A large Oirat state -Dzungar Khanate - was located to the south of Tara, and noble Oirat nomads collected tribute from the Turkic population of the uyezd. The reforms of Peter I made profound changes in the social world of Siberia. In the first third of the 18th century, the composition of the uyezd’s population was significantly altered. A new social group raznochintsy was formed of the relatives of servitors and clergy, and a large part of Tara’s service people were transferred to the garrison regiments of Siberia and the Orenburg governorate. The conflict between Tara’s horse Cossacks and captain Yakov Cheredov is indicative and important for understanding the service in favor of the state at that time. The Cheredovs were a deep-rooted clan of Russian service people who had lived in Tara since its founding. The Cheredovs held a number of important offices in Tara, and many of them became Boyar scions and nobles. After the 1722 Tara Rebellion, in which the Cheredovs played a significant role, they lost their privileged position and became raznochintsy . The ‘old’ service people who were nobles, Boyar scions and Cossacks remained the main military force in Siberian uyezds after the reforms. However, their dependence on the state increased. New garrison regiments in the region were formed in the 1730s, mostly of ‘old’ service people.

Досліджено перспективи впровадження нових інструментів матеріальної та персоніфікованої нематеріальної мотивації для зростання капіталізації торговельного підприємства. Запропонована методика інтегрованого застосування матеріальних і нематеріальних інструментів мотиваційного впливу на працівника якісно оновлює розуміння всіх елементів мотиваційної програми торговельної організації. Розрахунок конкретних показників матеріальної складової мотивації запропоновано узгодити зі стратегічними цілями капіталізації підприємства. Основна новація полягає в інтегруванні показників якості людського капіталу зі синтетичними показниками економічної спрямованості. Врахування критичних факторів успішності забезпечує динамічний взаємозв'язок цілей бізнесу і мотиваційних очікувань персоналу. Показано, що система матеріальної мотивації має ґрунтуватись на індикативному оцінюванні ефективності досягнення результатів кожним працівником на всіх рівнях організації. Запропонована методика визначення граничних розмірів матеріального стимулювання передбачає уніфіковане ранжування посад відповідно до їх функціональної значущості і реального внеску працівника у зростання капіталізації. Водночас ця методика поєднує в собі врахування особистісних мотиваційних очікувань персоналу і персоніфікацію їх відповідальності за капіталізацію організації.

When modeling myeloablation cytostatic chemotherapy with cyclophosphamide in rats fulminant hyperammonemia was observed accompanied by an increase in the content of ammonia and glutamine, a decrease in the content of pyruvic and lactic acids in brain tissue. A positive correlation between the indicators of azotemia and the content of ammonia and glutamine in brain tissue was established. In loading test with ammonium acetate changes in the chemical composition of blood and brain tissue were more pronounced. The data obtained indicate the intensification of the intake of gastrointestinal ammonia into the brain from the blood, which leads to the depletion of the tissue pool of pyruvate with the introduction of cyclophosphane in doses used for myeloablation. Such changes create the conditions for disruption of energy supply of neurological functions during myeloablative cytotoxic chemotherapy using cyclophosphamide.
Cathodoluminescence and trace-element chemistry of quartz from Sudbury offset dikes: Observations, interpretations, and genetic implications
Authors: Wehrle Elliot A. , McDonald Andrew M.
Published: December 2019

Offset dikes, radial and concentric fractures infilled with quartz diorite, are important hosts of Ni-Cu-PGE mineralization in the Sudbury area. To better understand their emplacement and evolution, the cathodoluminescence (CL) and trace-element chemistry of quartz were examined in quartz diorite from the Foy, Trill, Whistle, Hess, Parkin (North Range), and Copper Cliff (South Range) offsets. Although the potential causes of the CL response in quartz are considered, the primary focus was the qualitative textures and patterns, as these can provide valuable paragenetic information. Quartz from the North Range displays a strong blue luminescence dominated by homogenous and sharply zoned CL patterns, while that from the Copper Cliff offset displays a weak CL response. Locally recrystallized granoblastic quartz shows diffuse concentric zoning and other heterogeneous CL patterns. Trace-element EPMA-WDS analyses indicate that quartz from the Foy, Trill, and Whistle offsets is enriched in Al (30–600 ppm) and Ti (50–520 ppm) as compared to Fe (<25–490 ppm), while quartz from the Parkin and Hess offsets is enriched in Fe (270–700 ppm) as compared to Ti (44–211 ppm) and Al (95–250 ppm). In contrast to the North Range offsets, quartz from Copper Cliff has low Al concentrations (30–85 ppm) and very low Ti concentrations (<25 ppm). Application of the Ti-in-quartz geothermometer indicates that quartz from the North Range offsets crystallized above 600 °C, while that from the Copper Cliff offset crystallized below 600 °C. The CL responses and trace-element compositions of anhedral quartz from the North Range offsets are consistent with primary crystallization of quartz from magmatic quartz diorite, while those of the granoblastic quartz record dynamic recrystallization and Ostwald ripening. Copper Cliff quartz is anomalous in its CL response, trace-element content, and crystallization temperature, which may reflect overprinting during regional metamorphism of the South Range of the Sudbury Igneous Complex. Quartz CL is demonstrated to be an important tool for discerning and discriminating between paragenetic processes related to the formation of the offset dikes and has clear applications to the study of other quartz-bearing igneous rocks in the Sudbury area.
Identifying Atmospheres on Rocky Exoplanets through Inferred High Albedo

The upcoming launch of the James Webb Space Telescope means that we will soon have the capability to characterize the atmospheres of rocky exoplanets. However, it is still unknown whether such planets orbiting close to M dwarf stars can retain their atmospheres, or whether high-energy irradiation from the star will strip the gaseous envelopes from these objects. We present a new method to detect an atmosphere on a synchronously rotating rocky exoplanet around a K/M dwarf, by using thermal emission during secondary eclipse to infer a high dayside albedo that could only be explained by bright clouds. Based on calculations for plausible surface conditions, we conclude that a high albedo could be unambiguously interpreted as a signal of an atmosphere for planets with substellar temperatures of T
sub = 410–1250 K. This range corresponds to equilibrium temperatures of T
eq = 300–880 K. We compare the inferred albedos of eight possible planet surface compositions to cloud albedo calculations. We determine that a layer of clouds with optical depths greater than τ = 0.5–7, would have high enough albedos to be distinguishable from a bare rock surface. This method of detecting an atmosphere on a rocky planet is complementary to existing methods for detecting atmospheres, because it provides a way to detect atmospheres with pressures below 1 bar (e.g., Mars), which are too tenuous to transport significant heat but thick enough to host high-albedo clouds.
Comparison of the Scaling Properties of EUV Intensity Fluctuations in Coronal Hole and Quiet-Sun Regions

Published: December 2019

Using detrended fluctuation analysis and rescaled range analysis, we investigate the scaling properties of extreme ultraviolet (EUV) intensity fluctuations of low-latitude coronal holes (CHs) and neighboring quiet-Sun (QS) regions in signals obtained with the Solar Dynamics Observatory (SDO)/Atmospheric Imaging Assembly instrument. Contemporaneous line-of-sight SDO/Helioseismic and Magnetic Imager magnetic fields provide a context for the physical environment. We find that the intensity fluctuations in the time series of EUV images present at each spatial point a scaling symmetry over the range ∼20 minute to ∼1 hr. Thus we are able to calculate a generalized Hurst exponent and produce image maps, not of physical quantities like intensity or temperature, but of a single dynamical parameter that sums up the statistical nature of the intensity fluctuations at each pixel. In QS regions and in CHs with magnetic bipoles, the scaling exponent (1.0 < α ≤ 1.5) corresponds to anticorrelated turbulent-like processes. In CHs, and in QS regions primarily associated with (open) magnetic field of dominant polarity, the generalized exponent (0.5 < α < 1) corresponds to positively correlated (persistent) processes. We identify a tendency for α ∼ 1 near CH boundaries and in other regions in which open and closed magnetic fields are in proximity. This is a signature of an underlying 1/f type process that is characteristic for self-organized criticality and shot-noise models.

One of the curious observations from the Voyagers is that the intensity of anomalous cosmic rays (ACRs) did not peak at the heliospheric termination shock (HTS) but instead a short distance (within ∼1 au) downstream of the HTS. One possible explanation is that the interaction of the wavy heliospheric current sheet with the HTS enhances magnetic reconnection and generates numerous small-scale magnetic flux ropes in the heliosheath immediately downstream of the HTS. Charged particles are accelerated in this region due to Fermi acceleration and the reconnection electric field. In this work, we provide observational evidence of the presence of magnetic flux ropes in the heliosheath region just downstream of the HTS using a wavelet analysis of the reduced magnetic helicity and Grad–Shafranov reconstruction techniques. The Zank et al. kinetic transport theory for particles propagating through the magnetic islands region is employed to fit the observed energetic proton intensities in the post-HTS region. Our modeling results agree reasonably well with the observations, which suggests that stochastic acceleration via reconnection processes can explain the ACR proton peak beyond the HTS.
A new subspecies of African fire salamander Salamandra algira (Urodela, Salamandridae) from the Middle Atlas Mountains, Morocco
Authors: Hernandez Axel , Escoriza Daniel
Published: December 2019

A new subspecies within the Salamandra algira species complex from north-western Africa is described. Previous molecular analysis showed that the populations of S. algira splendens from north-western Morocco consisted of two well supported clades: clade 1 distributed in the Rif Mountains, from Chefchaouen (type locality) to Al Hoceima, and clade 2, located southern from clade 1 being isolated in the northern and central Middle Atlas Mountains. Clade 2 is herein described as a distinct subspecies: Salamandra algira atlanticassp. nov. based on morphological data, allopatric range and molecular divergence. This new subspecies shows an uncorrected pairwise distance of 0.0265 from clade 1 based on cytochrome b DNA sequences. Salamandra algira atlanticassp. nov. is a slender and large sized salamander with a highly variable colouration pattern. It can be distinguished from S. algira splendens by the greater proportion of coral red in the background colouration, being the only known subspecies of S. algira in which coral red can exceed the proportion of black. Variable number (0–5) of yellow to golden yellow dorsal blotches, but usually in lower numbers than the nominotypical subspecies. Salamandra algira atlanticassp. nov. inhabits subhumid to humid forests and karstic systems at mid to high elevations. We briefly discuss the phylogenetic and taxonomic issues among the genus Salamandra which encompasses more valid species than currently recognised.

Objective.

To examine the risk of type 1 diabetes (T1D) associated with juvenile idiopathic arthritis (JIA).

Methods.

Using the IBM MarketScan database, we compared JIA patients with asthma patients and healthy individuals for the risk of incident T1D.

Results.

We included patients with 15,210 JIA, 76,050 patients with asthma, and 76,050 healthy individuals matched 1:5 on age, sex, and index date. After adjustment for confounders, the multivariable HR of T1D associated with JIA was 1.48 (95% CI 0.86–2.56) versus asthma and 1.81 (95% CI 1.03–3.17) versus healthy individuals.

Conclusion.

JIA appears to be associated with an increased risk of T1D compared to patients with asthma and healthy children.
