In this work, the impact of various factors on the total ozone column and erythemal UV radiation (Qery) in the territory of Northern Eurasia for the period from 1979 to 2059 based on the calculations of the chemical-climate model INM-RHSU is analyzed. The sensitivity of ozone recovery to the setting of different input data on sea surface temperature (SST) is estimated. Depending on the SST datasets, there are significant differences in ozone trends. A possible mechanism that explains the reasons for these differences is examined. The numerical experiment with the only change in ozone depleting substances according to Montreal protocol showed the ozone recovery and, as a result, Qery reduction, but this recovery is not linear. During the 2016-2020 period we estimated the 2-5% increase in Qery values relative to the baseline period (1979-1983) with about 6% maximum over Russian polar region. During the 2035-2039 period the Qery change against 1979-1983 period is about zero, during the 2055-2059 period we obtained the decrease of about 4-6% over Northern Asia and 6-8% over Northern Europe These changes corresponded to the noticeable boundary location shift of UV resources, which determine UV radiation impact on human health. The most significant changes will be observed in spring and summer: the UV deficiency zone will be expanded in the north and the UV excess zone over northern seas will be reduced in the south.
Radiative instability of a barotropic jet flow in a stratified rotating atmosphere
Authors: Kalashnik M. V.
Published: June 2019

The problem of the stability of a jet flow with a piecewise linear velocity profile in a stratified rotating atmosphere is considered. The linearized system of equations for perturbations is reduced to a single equation with respect to the amplitude of the longitudinal velocity component containing the turning points. In terms of Airy functions, an asymptotic solution of the equation is constructed that is valid for small values of the Rossby number. It is shown that the flow becomes unstable due to radiation of inertial-gravitational waves. An analytical expression is obtained for the growth rate of perturbations.

Authors: Oganessian Yu. Ts.
Published: June 2019

Synthesis of superheavy elements predicted by microscopic nuclear theory is investigated. The heaviest elements with Z = 114–118 were synthesized by fusion reactions of actinide nuclei with 48Ca ions accelerated using the U-400 complex at the Flerov Laboratory of Nuclear Reactions (FLNR), one of seven laboratories that comprise the Joint Institute for Nuclear Research (JINR) located in Dubna, Russia. The experiments were carried out in collaboration with physicists and chemists working at the Livermore and Oak Ridge national laboratories in located in California and Tennessee, respectively. Discovery of these elements allowed completion of the seventh period of the periodic table. The microscopic nuclear theory’s fundamental predictions about the possible existence of superheavy elements received the experimental confirmation. A new laboratory, i.e., the "STE Factory" associated with the JINR FLNR, has been established to research superheavy nuclei.

The review of an exposition of the agricultural tractors presented at the international exhibition "Agrosalon 2018" which was taking place in Moscow from October 9 to October 12 is provided. Along with domestic manufacturers and the CIS countries: Petersburg Tractor Plant, the Rostselmash, the Bryansk tractor plant, the Minsk tractor plant), the products were exhibited and advertized by also leading global manufacturers of agricultural tractors: AGCO (USA) (Fendt, Challenger, Massey Ferguson, Valtra), Deere & Co (USA), Case New Holland (CNH) (USA). CLAAS (Germany). The Market of agricultural tractors of the Russian Federation is in a quantitative sense comparable to the markets of leaders of the European Union countries: Italy, Germany, France. The available qualitative differences are explained by features of agricultural production, the sizes of the agricultural enterprises and their infrastructure, a ratio in the park wheels and caterpillars tractors, solvent demand and other factors. In formation of the market of tractors the following directions gain development: accent shift towards tractors of high power with simultaneous strengthening of positions of tractors with driving wheels of the identical size (4k4b), special attention to caterpillars which are offered in options: traditional - two-caterpillar and nonconventional - four-caterpillar at which driving wheels of tractor 4k4b are replaced with the modules of triangular shape supplied with rubber-reinforced tracks .The following feature of the domestic market of tractors is existence of the real competition in segments: powerful tractors 4k4b, universal tractors of average power and also caterpillars of high power that is defined by a variety of offers and openness of the market of the agricultural equipment. The feature of the market is its heterogeneity on technological level of the offered machines that is explained first of all by different purchasing power of buyers. Studying of exhibits shows that the trends of development of designs of tractors, their units and systems noted by us when studying exhibitions "Agrosalon 2014" and "Agrosalon 2016" keep the actuality.

Dry magnetic separation (DMS) enables to separate the non-magnetic fraction of iron ores at the initial stage of their concentration and therefore to decrease cost of their further processing. However, a considerable amount of metal is lost in DMS tails at that. The efficiency of DMS considerably depends on difference between the upper and lower limits of the ore coarseness) ore coarseness range), delivered for concentration. At the Magnitogorsk steel-works crushing and concentration plant No. 5 this range is from 50 mm up to 15 mm. To determine the optimal ore size, delivered to DMS, studies accomplished to determine the specific magnetic susceptibility of the magnetite and the burden for the magnetite ore of Maly Kuibas deposit. After the study of different size iron ore separation, a reasonability of the DMS feed size decreasing down to 30–7 mm shown. A possibility to obtain additional product of 7–0 mm size determined, suitable for sintering. It will enable to decrease the amount of material, delivered for crushing and wet magnetic separation, as well as to decrease expenses for transporting and storage of wet separation tails. Peculiarities of fine magnetite ore processing by DMS in a suspended state considered, optimal parameters of the separator determined and its high efficiency for magnetite ore of 7–0 mm size concentration shown.

Published: June 2019

Actuality of steel-making slags utilization is stipulated not only by the necessity to improve ecology situation at the sites of slag piles, but also by a possibility to obtain additional raw materials for metallurgical production. Increase of the domestic iron-containing raw materials at Magnitogorsky steel-works can be done by more effective processing of steel-making slags. To improve the technology of BOF slags processing, a work done to study their chemical and mineral composition. It was established, that primary and secondary BOF slags are attributed to basic and ultra-basic, since the SiO2 mass share is less than 25–40%. Petrographic study results and data of IR-spectroscopy showed, that larnite, alite, monticellite and oxide RO-phase (Fe2+, Mn2+, Mg2+)O are main mineral components of the BOF slags. In many cases, the structure of the secondary BOF slags has middle-size grains, and the structure of primary slags is fine-grained. The texture of the secondary and primary slag is more often massive. The BOF slags have globules of iron, the size of which varies from sub-millimeters up to 5 mm. Study of influence of various methods of BOF slag particles destruction on the degree of globules disclosure showed, that application of centrifugal-striking crushing facilities provides more selective globules disclosure comparing with other methods. It was proved, that dry magnetic separation in suspended state, due to its peculiarities, provides higher technological indices comparing with drum separator when separating fine slags even at increase material moisture up to 5%.
Das Gespenst der Care-Krise
Authors: Maier Friederike , Schmidt Dorothea
Published: June 2019

In den letzten Jahren diagnostizierten viele Sozialforscher eine schwere Care-Krise sowohl im Bereich der bezahlten als auch der unbezahlten personenbezogenen Dienstleistungen. Care bezieht sich auf die  Bereiche Bildung, Gesundheit, Kinderbetreuung, Altenpflege und anderen Bereichen definiert, aber die Grenzen des Sektors bleiben oft unklar. Es wird argumentiert, dass Sorgearbeiten im Allgemeinen unterbewertet, vernachlässigt, feminisiert und sozial marginalisiert werden. Im Gegensatz zu dieser Ansicht argumentieren wir, dass diese Verallgemeinerungen der Bedingungen in bestimmten Teilen der Sorgearbeit nicht überzeugend sind. Wir argumentieren, dass es sinnvoller ist, die Entwicklungen von Fall zu Fall zu analysieren, um die soziale und gesellschaftliche Dynamik der Sorgearbeit zu verstehen. Zu diesem Zweck vergleichen wir zwei exemplarische Fälle: die Entwicklung der Kinder- und Altenpflege in Deutschland in den letzten Jahrzehnten. Sie unterscheiden sich nach dem Niveau der beruflichen Qualifikation, dem Gehalt der Mitarbeiter, den allgemeinen Arbeitsbedingungen und der Qualität der Dienstleistungen. Diese Unterschiede sind auf soziale Bewegungen zurückzuführen, die zu dem Verständnis geführt haben, dass Kinderbetreuung eine Angelegenheit der öffentlichen Verantwortung ist, während die Seniorenbetreuung weitgehend im Bereich der Privatsphäre gefangen blieb. Wir halten Verbesserungen in beiden Bereichen für notwendig, aber wir halten es für wichtig, anzuerkennen, dass sie Errungenschaften, Sackgassen, Nachteile und Widersprüche auf unterschiedliche Weise erlebt haben und nicht allzu leicht unter einer Rubrik zusammengefasst werden sollten.

Published: June 2019

Background. The main problems in nutrition among elderly people are insufficient consumption of high energy protein and deficiencies in vitamins and minerals. Obesity or malnutrition in this age group is also common. The character of the diet of the elderly is affected by many factors, including the place of residence.
Objective.The aim of this work was to compare the diet and nutritional status of elderly people living in nursing homes and in their family homes in West Pomeranian Voivodeship region.
Material and methods.The study was performed among 48 citizens of Drawsko Pomorskie (DP) and 79 residents of Nursery Home (NH) in Żabów. For the study we used a questionnaire containing questions about anthropometric data which served to assess nutritional state. The assessment of diets of the citizens of Drawsko Pomorskie was performed based on the menus collected using a 24-hour diet recall. Energy and nutritional value of the diets of NH residents were assessed on the basis of decade menus. Obtained results were compared to current recommendations.
Results.Two examined groups comprised of both underweight and obese people. The residents of NH in Żabów consumed more energy, protein, fat, cholesterol and carbohydrates, whereas people from DP – more dietary fibre. Diets of the citizens of DP were characterized by excessive consumption of sodium, phosphorus, iron, zinc, copper and vitamins: A, B2, B6, B12 and niacin, and insufficient consumption of potassium, calcium, magnesium and vitamins: D, E, C and folates. The diets of people living in family homes were excessive in sodium, phosphorus, iron, copper and vitamins: A, B1, B6, C and niacin, and contained too little calcium, magnesium and vitamins D, E and folates.
Conclusion. It was shown that the place of residence of examined people affected their diets and nutritional status. Both in case of people living in NH and in family homes there was a risk of underweight and obesity, which could be affected by improper way of nutrition.

Objective: To present a case of arteriovenous malformation of the mandible in a young postpartum woman and discuss the diagnostic and therapeutic dilemmas involved.

Methods:

          Design: Case Report

          Setting: Tertiary Private Teaching Hospital

          Participants: One 

Result: A 27-year-old woman with left mandibular swelling two weeks after tooth extraction was diagnosed and managed as a case of arteriovenous malformation. The extent of the lesion prevented surgical intervention and bleeding recurred despite three embolization attempts. Ultimately, the left external carotid artery and contralateral dorsal contributory vessel were sacrificed causing necrosis of the anterior tongue and its eventual detachment. Three sessions of stereotactic radiosurgery eventually controlled the bleeding with no recurrence to date.

Conclusion: On her second month following stereotactic radiosurgery, there appeared to be no complete resolution of the AVM but there was also no recanalization or regrowth of the lesion. Uncertain about whether her arteriovenous malformation will revascularize and how we may be able to help her in the event that it does, the waiting game continues for our patient.

Solitary Fibrous Tumor of the Larynx and Anterior Neck
Authors: Pabayos Guinevere S. , Chiong Armando M.
Published: June 2019

Whether benign or malignant, laryngeal and neck masses may involve the upper airway and obstruct breathing. While surgically-resectable malignancies are generally extirpated with adequate margins of normal tissue, benign lesions are usually excised conservatively. However, even benign masses may behave malignantly, necessitating more aggressive surgical resection. We present one such case.

 

CASE REPORT

 

A 35-year-old man from Cotabato City consulted due to difficulty of breathing.  He had a six-year history of progressively enlarging anterior neck mass with intermittent dyspnea, foreign body sensation, progressive dysphagia and hoarseness over the last three months. Physical examination revealed a well-defined, 5 x 6 cm smooth, firm, non-tender anterior neck mass that moved with deglutition.  Rigid endoscopy showed a right supraglottic mass with bulging of the right glottic and subglottic area, with a less than 10% airway opening. (Figure 1A) Both arytenoids were visibly mobile, but glottic closure was impaired. (Figure 1B) Tracheostomy and suspension laryngoscopy with biopsy yielded inconclusive results (fibromuscular tissue) and fine needle aspiration cytology (FNAC) of the anterior neck mass only revealed blood and colloid. Contrast computed tomography of the neck showed a well-marginated, hypodense, thick-walled, heterogeneously enhancing mass in the right laryngeal fossa measuring 2.86 x 1.78 cm with a larger extension anteriorly measuring 4.66 x 2.52 cm.  Effacement of the epiglottis and aryepiglottic fold was noted.  The hyoid and thyroid cartilage were intact, and the thyroid gland was normal.  (Figure 2A, B)

 

Because of inconclusive histopathological and cytological results, an incision biopsy of the anterior neck mass was performed.  Histopathological evaluation revealed spindle cell mesenchymal proliferation, and immunohistochemical stains showed positive immunoreactivity for CD34, with a weakly positive S-100 and negative SMA, favoring a solitary fibrous tumor.

The system introduces an intelligent facial emotion recognition using arti?cial neural network (ANN). The concept ?rst takes modi?ed local binary patterns, which involve horizontal vertical and neighborhood pixel comparison, to produce initial facial representation. Then, a microgenetic algorithm(mGA) embedded Particle Swarm Optimization(PSO), is proposed for feature optimization. It incorporates a nonreplaceable memory, a small-population secondary swarm, a new velocity updating strategy, a sub dimension based in-depth local facial feature search, and a cooperation of local exploitation and global exploration search mechanism to mitigate the premature convergence problem of conventional PSO. Arti?cial Neural Network is used as a classi?er for recognizing seven facial emotions. ANN is implemented as classi?er for pattern recognition. Based on a comprehensive study using within- and cross-domain images from the extended Japanese database. The empirical results indicate that our proposed system outperforms other state of-the-art PSO variants, conventional PSO, classical GA, and other related facial expression recognition models reported in the literature by a significant margin.

Ade Mulyana PEMBENTUKAN MAJLIS SYURA’ OLEH UMAR BIN KHATHTHAB UNTUK MENYELENGGARAKAN PEMILIHAN KHALIFAH
Authors: Mulyana Ade
Published: June 2019

Sejak Umar bin Khaththab ditikam oleh Abu Lu’lu’ah (Fairuz) kaum Muslimin dicekam oleh rasa ketakutan, khawatir akan nasib mereka sendiri kelak. Terpikir oleh mereka siapa yang akan menggantikannya jika dengan takdir Allah, Umar meninggal. Beberapa orang ada yang membicarakan masalah ini kepadanya. Mereka meminta Khalifah mencalonkan pengganti.

Pada mulanya Umar bin Khaththab ragu, dan ia berkata: “Kalaupun saya menunjuk seorang pengganti, karena dulu orang yang lebih baik dari saya juga menunjuk pengganti, atau kalaupun saya biarkan, karena dulu orang yang lebih baik dari saya juga membiarkan.” Tetapi sudah dipikirkan matang-matang, bahwa kalau dibiarkan begitu saja ia khawatir keadaan akan menjadi kacau. Dalam berperang dengan Persia dan Rumawi semua orang Arab sudah ikut serta sehingga setiap kabilah mengaku dirinya seperti kaum Muhajirin dan Anshar, berhak memilih khalifah. Malah di antara mereka ada yang mengaku  berhak mencalonkan pemimpinnya sebagai khalifah. Jika Umar bin Khaththab tidak memberikan pendapat, pengakuan seperti itu akan sangat membahayakan kedaulatan yang baru tumbuh itu.

            Karenanya, ia membentuk Majlis Syura’ yang terdiri dari enam orang dengan tugas memilih di antara mereka seorang khalifah sesudahnya. Keenam orang itu Utsman bin Affan, Ali bin Abi Thalib, Zubair bin Awwam, Thalhah bin Ubaidillah, Abdur-Rahman bin Auf dan Sa’d bin Abi Waqqas. Setelah menyebutkan nama-nama itu Umar berkata:”Tak ada orang yang lebih berhak dalam hal ini daripada mereka itu; Rasulullah Saw. wafat sesudah merasa puas terhadap mereka. Siapa pun yang terpilih dialah khalifah sesudah saya.”

Ahmad Zaini PENGATURAN PEMUTUSAN HUBUNGAN KERJA (PHK) MENURUT PERATURAN PERUNDANGAN-UNDANGAN KETENAGAKERJAAN
Authors: Zaini Ahmad
Published: June 2019

Salah satu bidang diantara bidang hukum perburuhan yang sangat penting jika dihubungkan dengan masalah perlindungan pekerja adalah bidang pemutusan hubungan kerja (PHK), terutama PHK yang dilakukan oleh majikan.Persoalan PHK menjadi mengemuka jika pengusaha ingin memutuskan hubungan kerja, padahal pekerja masih ingin tetap bekerja.Mengemukanya persoalan ini terletak pada keinginan pengusaha yang lazimnya serba kuat berhadapan dengan keinginan pekerja yang lazimnya serba lemah.

Masalah pemutusan hubungan kerja selalu menarik untuk dikaji dan ditelaah lebih mendalam. Tenaga kerja selalu menjadi pihak yang lemah apabila dihadapkan dengan piak pemberi kerja Tidak jarang para pekerja selalu mengalami ketidakadilan apabila berhadapan dengan kepentingan perusahaan.Tujuan utama  hukum perburuhan adalah untuk melindungi kepentingan buruh/pekerja. Tujuan tersebut dilandasi oleh filosofis dasar  bahwa buruh  selalu merupakan subordinasi dari pengusaha. Oleh karena itu, hukum perburuhan dibentuk untuk menetralisir ketimpangan tersebut. Dengan demikian, ketika undang-undang tidak mampu menyeimbangkan subordinasi tersebut, maka hal tersebut  terjadi karena kegagalan secara substansi dan kepentingan di lapangan yang lebih berpihak kepada para pengusaha.

Adanya wawasan Nusantara, wawasan kebangsaan dan wawasan bhineka tunggal ika maka idealnya Hukum Positif yang berlaku, baik yang tertulis, maupun yang tidak tertulis, tidak boleh membedakan golongan, keturunan, suku bangsa dan agama yang dianut-nya karena pembangunan hukum nasional juga harus memperhatikan wawasan kebangsaan dan wawasan bhineka tunggal ika. Asas hukum adalah ide yang mewakili sekalian bahan kultural yang dimasukkan ke dalam hukum sebagai landasan operasionalisasi nilai-nilai yang bersumber pada pandangan hidup bangsa yang diperlukan dalam pembentukan, penerapan, pelayanan, penegakkan maupun pengembangan akademik suatu tata hukum nasional, yang terdiri dari hukum tertulis maupun hukum tidak tertulis. Asas hukuk menyerap ide dan mewadahi ide dan pengalaman dan kekayaan kultur suatu bangsa. Maka asas Hukum Nasional (Indonesia) ditarik dari kekayaan kultural serta pengalaman  bangsa Indonesia.

Hukum Adat adalah Hukum Indonesia Asli, yang tidak tertulis dalam bentuk perundang-undangan Republik Indonesia, yang disana sini mengandung unsur agama.Hukum Pidana Adat adalah Hukum Indonesia Asli yang tidak tertulis dalam bentuk perundang-undangan yang disana-sini mengandung unsur agama, diikuti dan ditaati oleh masyarakat secara terus menerus, dari satu generasi ke generasi berikutnya.Pelanggaran terhadap aturan tata tertib tersebut dipandang dapat menimbulkan kegoncangan dalam masyarakat, karena dianggap mengganggu keseimbangan kosmis masyarakat.Oleh sebab itu bagi pelanggaran diberikan reaksi adat, koreksi adat atau sanksi/kewajiban adat oleh masyarakat melalui pengurus adatnya.

Sebagaimanan halnya bidang hukum yang lain, Hukum Pidana Adat juga memiliki sumber hukumnya, baik yang tertulis maupun yang tidak tertulis. Sumber hukum yang tidak tertulis adalah kebiasaan-kebiasaan yang timbul, diikuti dan ditaati secara terus menerus dan turun temurun oleh masyarakat adat yang bersangkutan. Sedangkan sumber tertulis dari Hukum Pidana Adat adalah semua peraturan-peraturan yang dituliskan baik diatas daun lontar, kulit,batu atau bahan lainnya. Hukum Adat akan terus tetap berlaku selama masyarkat hukum adat masih tetap ada dan tetap mempertahankannya.

Hak asasi manusia yang dipahami sebagai natural right merupakan suatu kebutuhan dari realitas sosial yang bersifat universal. Berdasarkan sudut pandang ini, sangat wajar sekali apabila hak asasi manusia telah berkembang sebagai suatu tatanan yang semula hanya sebatas negara tertentu saja, sekarang telah mendunia dan merupakan cerminan dari bermacam-macam norma perilaku yang diterima secara khusus oleh sebagian besar negara-negara di dunia. Asumsi inilah sebenarnya yang dijadikan sebagai dasar dari diterimanya pernyataan hak asasi manusia sedunia pada tahun 1948 oleh suatu badan internasional yaitu PBB. Namun harus disadari pula, salah satu masalah pokok yang dihadapi setiap upaya untuk melembagakan ide-ide pemajuan dan perlindungan hak asasi manusia adalah soal penegakan berbagai instrumen hak asasi manusia dalam praktek di negara-negara yang beranekaragam, baik dalam kondisi-kondisi sosial ekonomi dan budayanya maupun dalam tingkat perkembangannya masing-masing. Karena itu, sering muncul perbedaan yang kerap kali diawali dari adanya perbedaan pandangan, baik mengenai universalitas konsep hak asasi manusia itu maupun mengenai relativitas prosedural upaya-upaya untuk mengimplementasikan prinsip-prinsip hak asasi manusia yang universal

ASSOCIATION OF E-CADHERIN EXPRESSION TO CLINICAL STAGE OF NASOPHARYNGEAL CARCINOMA
Authors: Triastuti Felicia Melani , Asnir Rizalina A. , Yudhistira Ashri , Eliandy Sutoyo
Published: June 2019

Background: Nasopharyngeal carcinoma (NPC) has a high incidence rate in southern China and Southeast Asia and a high rate of metastasis in head and neck cancer. NPC is a squamous cell carcinoma that grows from the surface of the lateral wall of the nasopharynx. E-cadherin is known as a tumor suppressor protein and the loss of this expression in tumor cells is related to epithelial-mesenchymal transition that occurs during tumor development and metastasis.

Objective:To determine the relationship between E-cadherin expression and clinical stage in patients with nasopharyngeal carcinoma.

Methods: An analytical study with a cross-sectional study design, the number of samples was 30 patients with NPC who underwent immunohistochemical examination on KNF paraffin block.

Result: Overexpression of E-cadherin was found in T1 and T2 of 15 subjects (100%). The overexpression of E-cadherin was found in lymph node N2 and N3 of 19 subjects (95%). The overexpression of E-cadherin was found in the histopathological type of Non-Keratinizing Squamous Cell Carcinoma of 24 subjects (96%). The overexpression of E-cadherin was found at an advanced stage of 26 subjects (100%).

Conclusion: No significant association was found between E-cadherin expression and tumor size (p = 1,000), lymph node metastasis (p = 1,000), histopathological type (p = 1,000) and tumor stage (p = 0.133).

Published: June 2019

A reversed-phase HPLC method to determine total plasma warfarin was developed and validated. Warfarin was extracted from human plasma using a two-step liquid-liquid extraction method. The residue was reconstituted with a phenylbutazone standard solution, which was used as the internal standard. The analytical column was a Purospher STAR RP-18e (4 x 4mm I.D., 5m particle size). The mobile phase consisted of acetonitrile: potassium dihydrogen orthophosphate buffer solution at pH 6.5 [30:70 (v/v)] with a flow rate of 1mL/min. Both warfarin and phenylbutazone were detected using a photodiode array detector. The lower limit of quantification was 100ng/mL, while the limit of detection was 20ng/mL. The linearity of the assay was good (r2=0.992) in the concentration range from 0.1 - 6.0µg/mL. The extraction recovery of warfarin was 93.53 ± 12.40%. Both the intraday and interday quality control assay for warfarin demonstrated good precision and accuracy, with all of the percentage coefficients of variation being less than 15%. Warfarin was stable in human plasma for up to three months of storage. The validated method was successfully applied to four human samples for a pharmacokinetics study.
