Faktor-Faktor Yang Berhubungan Dengan Pemanfaatan Penolong Persalinan Di Desa Moyongkota Baru Kecamatan Modayag Barat
Latar belakang : Persalinan merupakan hal yang sangat kompleks karena disatusisi terjadi kebahagiaan menjelang kelahiran anak tetapi di sisilain terjadi resiko-resiko yang mungkin mengancam keselamatan ibu dan bayi. Di desa Moyongkota Baru Kecamatan Modayag Barat sebagian besar ibu bersalin memanfaatkan dukun sebagai penolong persalinannya dibandingkan dengan pemanfaatan penolong persalinan oleh tenaga kesehatan.Tujuan : Penelitian ini bertujuan untuk mengetahui faktor - faktor yang berhubungan dengan pemanfaatan penolong persalinan pada ibu bersalin di desa Moyongkota Baru Kecamatan Modayag Barat.Metode : Penelitian ini menggunakan desain penelitian observasional analitik dengan rancangan penelitian cross sectional study. Populasi dalam penelitian ini yaitu seluruh ibu yang bersalin pada bulan September – Oktober 2013 di Desa Moyongkota Baru Kecamatan Modayag Barat. Sampel yang digunakan adalah Quota sampling yaitu sampel dikumpulkan sampai mencapai jumlah yang diinginkan, jumlah sampel yang diinginkan adalah 50 responden.Hasil Penelitian : Berdasarkan hasil uji chi square diketahui bahwa faktor pengetahuan (ρ=0,006) dan dukungan suami (ρ=0,001) berhubungan signifikan terhadap pemanfaatan penolong persalinan, sedang kanfaktor status ekonomi tidak berhubungan signifikan dengan pemanfaatan penolong persalinan dengan nilai ρ=0,206.Kesimpulan : 58% ibu bersalin di desa Moyongkota Baru Kecamatan Modayag Barat Kabupaten Bolaang Mongondow Timur memanfaatkan penolong persalinan oleh dukun/paraji dibandingkan ibu bersalin yang memanfaatkan penolong persalinan oleh bidan (14%) dan penolong persalinan olehdokter (28%)
A Novel Polyoxotungstate [Ni<sub>4</sub>(H<sub>2</sub>O)<sub>2</sub>(α-NiW<sub>9</sub>O<sub>34</sub>)<sub>2</sub>]<sup>16-</sup> Based on an Old Structure with a New Component
A novel hexanuclear Ni-substituted polyoxometalate [Ni4(H2O)2(α-NiW9O34)2]16- (1) has been synthesized through a
hydrothermal method. Polyoxoanion 1 exhibits a usual tetranuclear sandwich-type structure based on unprecedented [α-NiW9O34]12- building
units and represents the first polyoxotungstate with four-coordinate nickel centers as heteroatoms
Tetra-Transition-Metal Substituted Weakley-Type Sandwich Germanotungstates and their Derivatives Decorated by Transition-Metal Complexes
Four classic discrete Weakley-type sandwich germanotungstates, Na11H[Co4(H2O)2(α-GeW9O34)2]·31H2O (1), [Co(phen)3]4H3[Co3W(H2O)2(α-GeW9O34)2]·4H2O (2), (C6N2H18)4[Co(H2O)6]H2[Co4(H2O)2(α-GeW9O34)2]·5.5H2O (3), Na(H2O)2(C6N2H18)4.75H1.5[Ni4(H2O)2(α-GeW9O34)2]·1.5H2O (4), and two novel germanotungstates decorated by transition-metal complexes (C6N2H18)3H2[{Co(2,2′-bpy)}2Co4(H2O)2(α-GeW9O34)2]·4H2O (5) (2,2′-bpy = 2,2′-bipyridine), [Ag(phen)2]6H2[{Mn(phen)}2Mn4(H2O)2(α-GeW9O34)2]·3H2O (6) (phen = 1,10-phenanthroline) were synthesized hydrothermally and structurally characterized by elemental analyses, IR spectra, and single-crystal X-ray diffraction structural analysis. Compounds 1−4 show the classical tetra-transition-metal substituted Weakley-type sandwich structural frameworks, whereas 5 and 6 represent the new Weakley-type sandwich frameworks decorated by different transition-metal complexes. EPR studies at 110 K and room temperature reveal that the high-spin paramagnetic metal ions (Co2+, Mn2+) reside in octahedral geometry in 3 and 6, respectively

Data_Sheet_1_Differentially Amplified Repetitive Sequences Among Aegilops tauschii Subspecies and Genotypes.zip
Genomic repetitive sequences commonly show species-specific sequence type, abundance, and distribution patterns, however, their intraspecific characteristics have been poorly described. We quantified the genomic repetitive sequences and performed single nucleotide polymorphism (SNP) analysis between 29 Ae. tauschii genotypes and subspecies using publicly available raw genomic Illumina sequence reads and used fluorescence in situ hybridization (FISH) to experimentally analyze some repeats. The majority of the identified repetitive sequences had similar contents and proportions between anathera, meyeri, and strangulata subspecies. However, two Ty3/gypsy retrotransposons (CL62 and CL87) showed significantly higher abundances, and CL1, CL119, CL213, CL217 tandem repeats, and CL142 retrotransposon (Ty1/copia type) showed significantly lower abundances in subspecies strangulata compared with the subspecies anathera and meyeri. One tandem repeat and 45S ribosomal DNA (45S rDNA) abundances showed a high variation between genotypes but their abundances were not subspecies specific. Phylogenetic analysis using the repeat abundances of the aforementioned clusters placed the strangulata subsp. in a distinct clade but could not discriminate anathera and meyeri. A near complete differentiation of anathera and strangulata subspecies was observed using SNP analysis; however, var. meyeri showed higher genetic diversity. FISH using major tandem repeats couldn’t detect differences between subspecies, although (GAA)10 signal patterns generated two different karyotype groups. Taken together, the different classes of repetitive DNA sequences have differentially accumulated between strangulata and the other two subspecies of Ae. tauschii that is generally in agreement with spike morphology, implying that factors affecting repeatome evolution are variable even among highly closely related lineages.</p

The
[HPMo<sub>6</sub>O<sub>21</sub>]<sup>2–</sup> units and carboxylate
linkers can be combined to build novel polyanions by a carefully designed
complementary system in self-assembly processes depending only on
the number of carboxyl groups and the nature of carboxylic acids.

which play the important templated role in assembly processes. The
stability of these clusters was explored using electrospray ionization

Novel Isopolyoxotungstate [H<sub>2</sub>W<sub>11</sub>O<sub>38</sub>]<sup>8–</sup> Based Metal Organic Framework: As Lewis Acid Catalyst for Cyanosilylation of Aromatic Aldehydes
A novel polyoxometalate-based metal
organic framework (POMOF) constructed
from isolated isopolyoxotungstate [H<sub>2</sub>W<sub>11</sub>O<sub>38</sub>]<sup>8–</sup> cluster, {[Cu<sub>2</sub>(bpy)(H<sub>2</sub>O)<sub>5.5</sub>]<sub>2</sub>[H<sub>2</sub>W<sub>11</sub>O<sub>38</sub>]·3H<sub>2</sub>O·0.5CH<sub>3</sub>CN} (<b>1</b>, where bpy = 4,4′-bpydine), has been synthesized under solvothermal
conditions and charaterized by elemental analysis, infrared spectroscopy,
and single-crystal X-ray diffraction. In <b>1</b>, {W<sub>11</sub>} clusters are alternately linked by two [Cu(2)(H<sub>2</sub>O)<sub>1.5</sub>(O<sub>t</sub>)<sub>3</sub>(N)]<sup>2+</sup> cations in
an unexpected end-to-end fashion leading to a one-dimensional (1D)
chain. Adjacent 1D chains are linked through Cu(1)–bpy–Cu(2)
in an opposite direction to form a two-dimensional (2D) wavelike sheet
along the <i>ab</i> plane. These 2D sheets are further stacked
in a parallel fashion giving rise to the 1D channels with copper(II)
cations aligned in the channels. The resulting POMOF acted as a Lewis
acid catalyst through a heterogeneous manner to prompt cyanosilylation
with excellent efficiency
