Health Inspection Procedures Handbook MSHA HANDBOOK SERIES U.S. Department of Labor Mine Safety and Health Administration Mine Safety and Health Enforcement December 2020 Handbook Number: PH20-V-4 Health Inspection Procedures Handbook PREFACE Miners can be exposed to many health hazards in mining. This handbook sets forth general procedures for conducting mine health inspections consistent with Section 103(a) of the Mine Act. This handbook supersedes previously issued instructions included in separate Coal and Metal and Nonmetal (M/NM) handbooks. The guidance will be general, and persons should refer to title 30 of the Code of Federal Regulations (CFR) that govern coal and other mines for specifics. Compliance related instructions in the MSHA Program Policy Manual remain in effect. The following sets forth guidance for a mine inspector when conducting mine health inspections, and inspection procedures should be consistent with mine conditions and practices. Not all procedures and requirements are applicable for all mine types. Any deviation from the procedures outlined in this handbook should be based on the inspector’s sound discretion, and that of the inspector’s supervisor. Timothy R.

  • Clinical Handbook Health Care for Children Subjected to Violence Or Sexual Abuse
    KINGDOM OF CAMBODIA NATION RELIGION KING MINISTRY OF HEALTH CLINICAL HANDBOOK HEALTH CARE FOR CHILDREN SUBJECTED TO VIOLENCE OR SEXUAL ABUSE 2017 PREFACE Violence against children is a serious public health concern and a human rights violation with consequences that impact their lives in various ways. Violence and sexual abuse suffered in childhood adversely affects the body as well as the mind, which can lead to a broad range of behavioral, psychological and physical problems that persist into adulthood. Healthcare practitioners play a significantly important role in prevention and response to violence against children. They are often the first or only point of reference for children who have experienced violence, detecting abuse and providing immediate and longer-term care and support to children and families. In 2015, the Ministry of Health developed “the National Guidelines for Management of Violence Against Women and Children in the Health Sector”, which provides health care centers and referral hospitals with an overview of prevention and response in the health sector to violence against women and children. This “Clinical Handbook on Health Care for Children Subjected to Violence or Sexual Abuse” elaborates on knowledge and skills required to implement the National Guidelines. It aims to serve as a guide to ensure a prompt and adequate response to child victims of violence or sexual abuse for all healthcare practitioners. It provides further guidance on first line support, medical treatment, psychosocial support, and referral to key social and legal protection services. It can be also used as a resource manual for capacity development and training. Phnom Penh, 30th January 2017 Prof.

Block ~ ( Institute for Materials Research, National Bureau of Standards, Washington, D.C. 20234 I (May 23, 1966) BaGe[Ge30gl is trigonal, space group P3, with lattice constants a= 11.61, c=4.74 A, and Z =3. The structure was established by three·dimensional Patterson and electron density syntheses. Three·dimensional least·squares refinement resulted in a final R value of 6.8 percent (observed data only). The previously proposed structural relationship of this compound with benitoite, BaTiSbOg, has been confirmed. The structure can be considered as composed of Ge30g rings, in which the Ge is tetrahedrally coordinated, linked through octahedrally coordinated Ge atoms to form a three·dimen· sional Ge·O network. All Ge polyhedra are linked by corner sharing. The Ba ions occupy positions in channels of the network. Key Words: Barium tetragermanate, structure, benitoite, crystal, x·ray. 1.

Tis is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Native sulfur deposits on fumarolic felds at Ebeko volcano (Northern Kuriles, Russia) are enriched in chalcophile elements (As- Sb-Se-Te-Hg-Cu) and contain rare heavy metal sulfdes (Ag2S, HgS, and CuS), native metal alloys (Au2Pd), and some other low- solubility minerals (CaWO4, BaSO4). Sulfur incrustations are impregnated with numerous particles of fresh and altered andesite groundmass and phenocrysts (pyroxene, magnetite) as well as secondary minerals, such as opal, alunite, and abundant octahedral pyrite crystals. Te comparison of elemental abundances in sulfur and unaltered rocks (andesite) demonstrated that rock-forming elements (Ca, K, Fe, Mn, and Ti) and other lithophile and chalcophile elements are mainly transported by fumarolic gas as aerosol particles, whereas semimetals (As, Sb, Se, and Te), halogens (Br and I), and Hg are likely transported as volatile species, even ∘ at temperatures slightly above 100 C.

    Geochemical Journal, Vol. 41, pp. 149 to 163, 2007 Boron isotope fractionation accompanying formation of potassium, sodium and lithium borates from boron-bearing solutions MAMORU YAMAHIRA, YOSHIKAZU KIKAWADA* and TAKAO OI Department of Chemistry, Sophia University, 7-1 Kioi-cho, Chiyoda-ku, Tokyo 102-8854, Japan (Received March 18, 2006; Accepted June 22, 2006) A series of experiments was conducted in which boron minerals were precipitated by water evaporation from solutions containing boron and potassium, sodium or lithium at 25°C, and boron isotope fractionation accompanying such mineral precipitation was investigated. In the boron-potassium ion system, K2[B4O5(OH)4]·2H2O, santite (K[B5O6(OH)4]·2H2O), KBO2·1.33H2O, KBO2·1.25H2O and sassolite (B(OH)3) were found deposited as boron minerals. Borax (Na2[B4O5(OH)4·8H2O) was found deposited in the boron-sodium ion system, and Li2B2O4·16H2O, Li2B4O7·5H2O, Li2B10O16·10H2O, LiB2O3(OH)·H2O and sassolite in the boron-lithium ion system. The boron isotopic analysis was con- 11 10 ducted for santite, K2[B4O5(OH)4]·2H2O, borax and Li2B2O4·16H2O. The separation factor, S, defined as the B/ B isotopic ratio of the precipitate divided by that of the solution, ranged from 0.991 to 1.012. Computer simulations for modeling boron mineral formations, in which polyborates were decomposed into three coor- dinated BO3 unit and four coordinated BO4 unit for the purpose of calculation of their boron isotopic reduced partition function ratios, were attempted to estimate the equilibrium constant, KB, of the boron isotope exchange between the boric – acid molecule (B(OH)3) and the monoborate anion (B(OH)4 ).

  • PABSTITE from the DARA-I-PIOZ MORAINE (TADJIKISTAN)
    New data on minerals. M.: 2003. Volume 38 UDC 549.6 PABSTITE FROM THE DARA-i-PIOZ MORAINE (TADJIKISTAN) Leonid A. Pautov Fersman Mineralogical Museum of the Russian Academy of Science. Moscow, [email protected] Pabstite was discovered in the moraine of the Dara-i-Pioz glacier (Garmsky district, Tadjikistan) in a leuco- cratic rock mainly composed of microcline, quartz, and albite. Subordinated minerals are aegirine, titanite, astrophyllite, bafertisite, galena, sphalerite, ilmenite, pyrochlore, fluorite, zircon, fluorapatite, and calcite. Pabstite forms grains and well-faced crystals (0.1-0.5 mm), growing on quartz crystals in small cavities abun- dant in the rock. Its composition is close to the final member BaSnSi:P9 in the series pabstite-benitoite. Microprobe analysis has shown: SiO, - 37.43; Ti02 - 0.19; Zr02 - 0.16; Sn02 - 30.05; BaO - 32.41; total 100.24. The empirical formula is Balo2(Sno96Tio.01Zroo,)o98Si3o,09'Refraction parameters of pabstite are no = 1.668(2); 1.657(2), which is much lower than cited figures for pabstite from the type locality. Strong n" = dependence of pabstite optical properties on titanium contents is shown. The find of pabstite at Dara-i-Pioze is the first find of pabstite in alkaline rocks and, apparently, the second find of this mineral in the world. 2 tables, 3 figures and 13 references. Pabstite BaSnSi30g, the tin analogue of beni- aegirine syenites and foyaites.

Stenstrom, Chair Many parts of the world are experiencing severe water drought and it affects societies both economically and environmentally. Therefore, conservation practices are essential to balance water supply and demand. Greywater or wastewaters from showers and luandries, if treated well can be a reliable source for activities such as irrigation, toilet flushing and car washing. Greywaters are not as contaminated as sewage but still may require treatment before reuse. The application of insufficiently treated water for irrigation can cause harm to plants and animals. Pollutant such as boron in greywater is of particular interest because many plants are sensitive to even low concentrations. High concentrations of boron can induce toxicity, reduce growth rate and yield in plants. Therefore, proposed greywater treatment systems need to consider the sensitivity of plant species and boron concentrations and potential removal. This thesis reviews boron chemistry, its effect on plants and currently available boron removal technologies.
