Grandidierite, (Mg,Fe)Al3O2(BO3)SiO4, was found in a garnet-clinopyroxene-ilmenite-rich mafic granulite from Austhovde in the Late Neoproterozoic to Early Cambrian Lützow-Holm Complex (LHC), East Antarctica, the first reported occurrence of this borosilicate in a mafic granulite. It occurs in one of the many nanogranitoid inclusions (NIs) in garnet. Quartz, sodic plagioclase, myrmekite, K-feldspar, epidote and biotite are also found only as inclusions in garnet. Garnet porphyroblasts show marked compositional zoning: Ca increases and Mg decreases from the core to rim with little change in Fe and Mn contents except for the outermost rim. Anorthite content of inclusion plagioclase increases from core to rim of host garnet in parallel with increase in garnet Ca towards the rim. This together with the distinctly different mineral assemblages within and exterior to garnet porphyroblasts suggests that partial melting took place and produced melts were extracted leaving a mafic and calcic restite. Partial melting also occurred locally in garnet porphyroblasts consuming different hydrous mineral inclusions to produce various NIs ranging from K-feldspar-rich to K-feldspar-free. Subsequent decompression at high temperatures resulted breakdown of garnet to orthopyroxene + calcic plagioclase with further consumption of quartz, such that none remained in the matrix of the granulite. Grandidierite may have formed by a reaction between a trapped boron-bearing aluminous granitic melt and host garnet upon cooling.

In this study the validity of an accreditation system that applies a uniform standard to measure various early childhood education facilities in Indonesia was examined. Accordingly, recommendations for future accreditation systems are proposed.  The subjects of the study included formal and non-formal early childhood education facilities under the jurisdiction of the Ministry of Education and Culture. The Ministry’s policy documents, statistics, and related laws and regulations were analyzed to determine the establishment criteria for early childhood education in Indonesia, and the characteristics and results of the accreditation system.  The analysis revealed that many formal and non-formal education Facilities were rated inadequate TT because of the flexible criteria for establishing early childhood education and varying services in the facilities. However, these Facilities were reviewed uniformly with similar criteria in the accreditation process. Furthermore, parents did not base their selection of early childhood education facilities on accreditation results because TT-rated facilities were still operating post-accreditation.

Growing industrialization and urbanization are seriously polluting the environment with hazardous heavy metals. Heavy metal pollution has caused major consequences on human health and the environment on a global level. Economically effective and environmentally friendly methodologies and technologies are utilized globally to remediate heavy metal-contaminated soils and wastewater. Phytoremediation is one of the potential technologies for the in-site treatment of heavy metal-contaminated soil and water. Over 163 plant species with the ability of metal concentration and tolerance have been discovered in the world as possible phytoremediators. Among the plant species used for phytoremediation, Cyprus rotundus is a safe and inexpensive phytoremediation agent that has a high capacity to accumulate heavy metals in its plant parts. This review provides a general overview of the phytoremediation potential of Cyperus rotundus through reviewing relevant originally published research articles. For the study, a literature survey was conducted by using articles from top academic research databases including ScienceDirect, JSTOR, Google Scholar, and PubMed. A total number of 71 originally published articles related to phytoremediation and heavy metal phytoremediation of Cyperus rotundus were selected for the review. According to previous studies, Cyperus rotundus is capable of extracting and accumulating As, Cd, Pb, Rb, Sn, and Zn in its roots and shoots when the soil is highly polluted with the aforementioned heavy metals. Moreover, Cypreus rotundus indicate a considerable value of bioconcentration factors and translocation factors to different heavy metals, whereas it emphasizes the possible remediation of heavy metals through this plant species. Consequently, Cyperus rotundus could be identified as a possible hyperaccumulator and Phytostabilizer for most heavy metals for upcoming phytoremediation studies.

Observations of the geomagnetic total intensity have been carried out from time to time in a possible seismic gap region in the western part of the North Anatolian Fault Zone (NAFZ), in an attempt to trace faultlines through magnetic characteristics and also to relate the characteristics to fault activity. Here we report the results of profile measurements made across the Iznik-Mekece fault as well as our interpretation. The anomalies which we found near Iznik City are similar with the ones that have been found along the eastern part of the Iznik-Mekece fault and hence they could be interpreted in terms of a dike-like structure in the andesite zone adjacent to the fault. In this area the northern edge of the dike-like structure turns out to correspond to the faultline, providing a piece of evidence for the location of faultline. In addition, the dip angle of the dike-like structure provides information on the dip-slip constituent of the primarily right-lateral Iznik-Mekece fault.

Objective: The aims of this study were to: 1) quantify the weekly volume of sets prescribed for each muscle group of the lower limbs in recreationally-trained women; 2) assess the association between resistance training experience and the weekly volume. Design and Methods: The training programs of 1019 recreationally-trained women subjects were analyzed. Data was ana lyzed for the following lower limb muscle groups: quadriceps femoris, knee flexors, hip adductors, gluteus medius, gluteus maximus, triceps surae, and tibialis anterior. A k-cluster analysis was performed to subdivide the weekly volume of sets into 3 groups (low, medium, and high). Results: A significant difference in RT experience (years) and weekly frequency was observed between the 3 groups. For relative (%) weekly volume of sets, a larger number was noted for quadriceps femoris (34.29%), followed by gluteus maximus (28.57%), knee flexors (11.43%), and hip adductors, gluteus medius and triceps surae (all 8.57%). A moderate correlation was observed between RT experience and AVS (rs = 0.56; 95% CI = 0.50 to 0.59; p = 0.001) and a strong correlation between weekly frequency and AVS (rs = 0.73; 95% CI = 0.69 to 0.75; p = 0.001). Conclusion: In conclusion, strength coaches usually prescribe high weekly volumes of sets for lower limb muscle groups. Additionally, a higher weekly volume of sets was prescribed for the quadriceps femoris and gluteus maximus muscles when compared to the knee flexors. This results suggest that training experience positively correlates with to the absolute weekly volume of sets.

インド産のクビワスナバシリ Jerdon's Courser Rhinoptilus bitorquatus は一時絶滅と考えられていたが(1952~1982),Bhushan(1986)によって再発見された。本種に近縁のアフリカとインドの8種を19の形質(形態特徴と昼夜行性)についてPAUP分岐分析法(相対形質を0と1または2,3と置く)で比較したところ,アフリカ産のウロコクビワスナバシリR.cinctusと近い姉妹種であることが証明された。これは生物地理学的に東アフリカからアラビアを介してインドに連なる乾燥帯があったことを示唆し,このアフリカーインド動物相(Afro-Indian fauna)は他の鳥類約40種や獣類でも立証される(一般にはアジアーインド系の湿性林が重視されるが)。この希種の保護には姉妹種 R.cinctus を人工繁殖させ本種 R.bitorquatus の卵を孵化させる方法をとれば,生息地保護や教育に加えて効果があると思う。

Background: Lower respiratory tract infections (LRTIs) are a cause of inpatient and outpatient care among children. Although orofacial clefts seem to be associated with LRTIs, epidemiological studies are scarce on this topic. This study aimed to examine whether infants with orofacial clefts were associated with LRTIs.Methods: This prospective cohort study used data from the Japan Environment and Children’s Study, for which baseline recruitment was conducted during 2011–2014. This study included 81,535 participants. The number of infants with cleft lip and palate (CLP), cleft lip (CL), and cleft palate only (CP) was 67, 49, and 36, respectively. We defined history of LRTIs until 12 months’ age reported by their mothers as the dependent variable. Accumulated breastfeeding duration was used as a potential mediator.Results: The incidence proportion of LRTIs among the control group was 6.0%. The incidence proportion among infants with CLP, CL, and CP were 11.9%, 14.3%, and 5.6%, respectively. After adjusting for covariates, compared with the control group, infants with CLP and CL were associated with risk of LRTIs (incidence risk ratio [IRR] of CLP, 2.38; 95% confidence interval [CI], 1.30–4.36 and IRR of CL, 2.73; 95% CI, 1.40–5.33), but not ones with CP (IRR 1.08; 95% CI, 0.28–4.15). Accumulated breastfeeding duration decreased the IRR of CLP only (IRR of CLP, 2.16; 95% CI, 1.19–3.93).Conclusion: Infants with orofacial clefts aged 1 year have a potentially high incidence proportion of LRTIs. Accumulated breastfeeding duration might mediate the associations of CLP.

Background: The Japan Environment and Children’s Study (JECS) is a nationwide birth cohort study investigating environmental effects on children’s health and development. A Sub-Cohort Study has begun, conducting extended exposure and outcome measurements by targeting a subgroup randomly selected from the JECS Main Study. We report the Sub-Cohort Study methodology and participants’ baseline profiles.Methods: Of 100,148 children in the JECS Main Study, children born after April 1, 2013 who met eligibility criteria ([1] all questionnaire and medical record data from children and their mothers collected from the first trimester to 6 months of age, [2] biospecimens [except umbilical cord blood] from children and their mothers collected at first to second/third trimester and delivery) were randomly selected for each Regional Centre at regular intervals. Face-to-face assessment of neuropsychiatric development, body measurement, paediatrician’s examination, blood/urine collection for clinical testing and chemical analysis, and home visits (ambient and indoor air measurement and dust collection) are conducted. Participants are followed up at 1.5 and 3 years old for home visits, and 2, 4, 6, and 8 years old for developmental/medical examination. The details of protocols after age 10 are under discussion.Results: Of 10,302 selected children, 5,017 participated. The profiles of the participating mothers, fathers and children did not substantially differ between the Main Study and Sub-Cohort Study.Conclusion: The JECS Sub-Cohort Study offers a platform for investigating associations between environmental exposure and outcomes.
