Introduction: Stature estimation from the skeletal remains bears immense importance for the anatomist, an­thropologist for the forensic experts. It is conventionally used long bones, the humerus, femur, tibia, etc. Ulna has also been used for the said purpose since 1952. An attempt was made to formulate a linear regression equation for the estimation of the stature of living adult population from the lengths of their ulna. Methods: This study was conducted in the M.B. Kedia Dental College Birgunj from January 2017 to December 2017and participants were chosen from among the patients and their attendants in the OPD. The height was measured from the crown to the heel and the length of the ulna was measured from the tip of the olecranon process to the tip of the styloid process. The documented data was calculated by the standard statistical software. Results: The parameters were tabulated and statistically analyzed. The correlation coefficient (r) was found to be 0.399 (p<0.001) for the left ulna with stature and it was 0.486 (p<0.001) for the right ulna with stature. Supportive regression equations and scatter-plot diagrams could successfully interpret the height from the ulna length of the adult male population. Conclusion: The ulna being almost a percutaneous bone, it can be used for the prediction of the height. The ulna length provides an accurate and reliable means in estimating the height of an individual. The regression formulae which were proposed in this study will be useful for clinicians, anatomists, archeologists, anthropologists and forensic scientists when such evidence provides the investigator the only op­portunity to gauge that aspect of an individual’s physical description.

Perairan Teluk Banten merupakan wilayah yang sibuk dengan aktivitas wisata bahari, industri, permukiman dan lain-lain. Kondisi tersebut dapat menimbulkan dampak-dampak negatif seperti pencemaran, erosi, dan masalah lingkungan lainya. Pemahaman mengenai kondisi hidro-oseanografi sangat penting sebagai langkah untuk pengelolaan dan perlindungan wilayah pesisir dan laut. Tujuan dari penelitian ini untuk mengetahui karakteristik hidrodinamika di Perairan Teluk Banten pada musim peralihan (Agustus - September) berdasarkan data primer (data satu bulan arus, pasang surut, suhu) dan data sekunder (batimetri, kualitas air dan nutrient). Simulasi model diolah menggunakan MIKE 21, didukung dengan penggunaan CD-Oceanography. Hasil pengolahan data menunjukkan bahwa pola arus di Perairan Teluk Banten didominasi arus pasut dengan kecepatan berkisar antara 0-0,41 m.s-1, ditunjukkan oleh hasil pengolahan dalam bentuk stick diagram dan scatter plot yang menunjukkan pergerakan arus cenderung teratur dan arah arus dominan menuju ke arah Tenggara dan Selatan, hal ini juga didukung dengan hasil Current rose dengan menggunakan software WR plot. Kecepatan arus di permukaan lebih besar dan menyebar dibanding kecepatan arus di dekat dasar perairan. Simulasi arus permukaan (nilai error MRSE 12,25 %) menunjukkan bahwa arus bergerak sesuai dengan pengaruh pasang dan surut dengan kecepatan berkisar antara 0-0,42 m.s-1. Simulasi juga memperlihatkan distribusi konsentrasi nutrient dan kualitas perairan dipengaruhi oleh karakteristik hidrodinamika Teluk Banten.

Purpose This paper aims to reduce and eliminate the abnormal peaks which, because of the reflection in the process of laser detection, make it easier to proceed with further analysis. Design/methodology/approach To solve the above problem, an abnormal data correction algorithm based on histogram, K-Means clustering and improved robust locally weighted scatter plot smoothing (LOWESS) is put forward. The proposed algorithm does section leveling for shear plant first and then applies histogram to define the abnormal fluctuation data between the neighboring points and utilizes a K-Means clustering to eliminate the abnormal data. After that, the improved robust LOWESS method, which is based on Euclidean distance, is used to remove the noise interference and finally obtain the waveform characteristics for next data processing. Findings The experiment result of liner tool mark laser test data correction demonstrates the accuracy and reliability of the proposed algorithm. Originality/value The study enables the following points: the detection signal automatic leveling; abnormal data identification and demarcation using K-Means clustering and histogram; and data smoothing using LOWESS.

Abstract: Patients with end-stage renal failure are unable to survive without dialysis or renal transplantation. To achieve effective dialysis using a double lumen catheter, placement of the catheter tip plays an important role because it may affect blood flow/Quick of Blood (QB). The selection of femoral vein access is more favorable in critical patients. This study was aimed to obtain the correlation between the tip position of the non-tunneling short-term femoral double lumen catheter (DLC) and QB at the time of hemodialysis. This was an analytical correlative and prospective study with a cross-sectional design in patients with end-stage renal failure undergoing hemodialysis using a non-tunneling short-term femoral DLC. This study was conducted at the Hemodialysis Installation of Prof. Dr. R. D. Kandou Hospital Manado. Data were analyzed by using the Pearson's r test. The results showed that there were 31 patients enrolled in this study. The Pearson’s r test obtained an r of 0.147 (statistically weak) and Sig (2-tailed) of 0.430 which showed no correlation but the scatter plot showed a tendency of a weak positive relationship. Conclusion: There was no significant correlation between Qb and the tip position of DLC, albeit, there was a tendency of a weak positive relationship. Increasing the number of samples will more accurately predict the presence or absence of the correlation between Qb and the tip position of the DLC.Keywords: DLC, QB, hemodialysisAbstrak: Pasien dengan penyakit ginjal stadium akhir tidak dapat mempertahankan hidup tanpa dukungan terapi pengganti ginjal yaitu dialisis atau transplantasi ginjal.

Abstract. Data-sparse zones in scatter plots of hydrological variables can be of interest in various contexts. For example, a well-defined data-sparse zone may indicate inhibition of one variable by another. It is of interest therefore to determine whether data-sparse regions in scatter plots are of sufficient extent to be beyond random chance. We consider the specific situation of data-sparse regions defined by a linear internal boundary within a scatter plot defined over a rectangular region. An Excel VBA macro is provided for carrying out a randomisation-based significance test of the data-sparse region, taking into account both the within-region number of data points and the extent of the region. Example applications are given with respect to a rainfall time series from Israel and to validation scatter plots from a seasonal forecasting model for lake inflows in New Zealand.

Cassava, a crop widely adapted in the tropics, has the important attribute of withstanding adverse environmental conditions better than do many other staple crops. The performance of an individual genotype, however, is influenced by the environment in which it grows. In Malawi, the heterogeneity of agro-ecologies requires the cumbersome and costly assessment of new cassava genotypes at many sites. This study was conducted, therefore, to test the feasibility of selecting only a few locations for cassava evaluation that would be representative of all the agro-ecologies in which cassava is grown in Malawi. Enormous environmental effects, largely contributed by the interaction between season and location, were manifested. Genotype×environment interaction, due largely to a third level interaction (genotype×season×location), was highly significant for all the traits studied. A principal component analysis scatter plot showed no particular grouping of environments, but a pair-wise comparison showed that some of the locations had limited genotype×environment interaction, indicating that it would be sufficient to use one of these sites for evaluating these traits. The value of the residual was often large, probably as an effect of environmental heterogeneity in the test sites. The authors conclude that cassava genetic improvement will continue to be slow if Malawi is used as a single breeding zone. They recommend a much finer grouping of the locations and the use of smaller plot sizes to allow more clones to be tested at more sites for the same cost. Locations may be selected for intensive cassava breeding work from those that give the best discrimination between genotypes while having insignificant genotype×environment interactions in a relatively large number of environments.
