Analysis of weekly rainfall of different period during rainy season over Safdarjung airport of Delhi for 20th century – A study on trend, decile and decadal analysis

The analysis of weekly rainfall and of different period during rainy season of Safdarjang airport using techniques like trend and decile have been attempted. Decadal analysis is also attempted to see any changes during the entire period. Rainy season is defined as rainfall received from week no. 23rd to 38th. Weekly rainfall data for period 1901 to 2000 is utilized for this location. As week is a shorter period to analyze rainfall for the season groups of different periods consisting of 4 weeks such as 1-4 as ‘A’, 5-8 as ‘B’ and so on up to ‘D’ is formed. For study of progressive season combination of groups such as ‘A+B’, A+B+C and ‘A+B+C+D’ are also subjected to analysis as done for weekly as well for group. The average weekly rainfall distribution indicates very high positive value of coefficient of correlation (0.94) significant at 1% level. The coefficient variation (C.V.) of weekly average rainfall shows consistency from decade 5th to 8th and 10th. Profile of average C.V. of weekly rainfall for 100 years shows consistency from week 4 to 11. Week no. 8 shows peak of rainfall. Overall decile analysis of weekly rainfall shows increasing tendency from week no. 1 to 8 for all deciles and then decreasing tendency from week no. 9 on words for all decile values. Trend analysis of group ‘C’ shows significant positive tendency with correlation as +0.20 significant at 5% level. However trend analysis of deciles of all groups shows very high C.C. around +0.95 at 1% level. Trend analysis of combination of groups shows positive trend for A+B+C and for A+B+C+D with a C.C. of 0.25 and 0.20 at 5% level. Trend of deciles for these groups also shows very high C.C. values around +0.95 at 1% level. Average, excess and deficient rainfall seen at Safdarjung airport is 5th, 7th and 4th decile with values as 594, 708 and 472 mm respectively. Analysis of two halves of century, viz., 1901-50 and 1951-2000 shows no significant trend.

STRENGTHENING LAND REGISTRATION SYSTEM THROUGH IMPLEMENTATION OF DOMAIN APPROACH IN MANIFESTING LEGAL CERTAINTY AND COMMUNITY JUSTICE

As an implementation of welfare society, the government issued Law Number 5 of 1960 Article 19 paragraph (2) c, which provide the legal certainty of land rights for all Indonesians carried out through land registration. The land registration system adopted by Indonesia is negative land cadastre with positive tendency. The implementation of land registration provide the basis of state duty to produce land registration evidence, namely certificate, which is valid as a strong proof of rights. This certificate guarantees the correctness of physical data besides juridical data as long as it is not proven otherwise. Method: This legal research used Normative juridical method, with qualitative juridical data analysis. Results of the study: Negative land cadastre with positive tendency adopted by Indonesia currently does not guarantee legal certainty of land ownership and the community justice itself. This is indicated by the fact that there is still a phenomenon of land disputes, among the result of the issuance of overlapping. By using a legal cadastre-based domain approach, through an approach of extracting historical values of land and integrating the process of dialogue within the issuing of certificate; obtaining legal certainty and the community justice can be achieved. Conclusion: Negative land cadastre with positive tendency is still unable to manifest legal certainty of land ownership and community justice so it is appropriate that an adage states “the highest legal certainty, is the highest injustice”. Strengthening land registration system through the domain approach is an alternative option to manifest legal certainty and community justice.

Total ankle replacement

Introduction Total ankle replacement is definitely a tough issue for both orthopedic surgeons treating patients with ankle pathology and engineers who develop optimal implant constructs. Extreme short-time kinetic loads, complex motion biomechanics, anatomic features of the ankle result in high demands for ankle joint implants. In general, there is a positive tendency in an annual increase of the number of total ankle replacements. Alongside, a significant lagging in performing this procedure and the tendency for ankle arthrodesis has been observed in Russia. Aim To review the literature data about development and current status of total ankle replacement. To evaluate the use of modern implants for distal tibia replacement. Material and methods The given literature review includes analysis of foreign and domestic publications focused on issues of treatment of osteoarthritis of the ankle joint and tumors of the distal tibia. The information was searched for using GoogleScholar, PubMed, eLIBRARY, PubMedCentral in the Russian and English languages with the following keywords: total ankle replacement, ankle arthrodesis, ankle osteoarthritis, distal tibia replacement. Discussion Currently, there are controversies in selection of biomaterials and constructive parameters for ankle implants. Separately, there is an unsolved issue of selecting the optimal friction pair for bearing surfaces, as well as of operative technique features, such as implant fixation, surgical approach, modeling and restoration of the capsular-ligamentous complex. Conclusion Total ankle replacement is an effective alternative procedure to ankle arthrodesis and limb-sacrificing operations. To improve treatment results, optimal implant construction, fixation methods, selecting appropriate friction pair and capsular-ligamentous complex restoration should be further investigated in complex studies.

Assessing attitudes of patient-centered care among chiropractic students at a South African university

Objective Patient-centered care (PCC) is acknowledged globally as a foundation of quality patient care and key to doctor–patient rapport. Student attitudes toward PCC have been assessed in some health professions and some international chiropractic institutions but is lacking in the South African chiropractic student context. This study explores this concept and compares these attitudes to other student groups. Methods A cross-sectional survey was conducted on chiropractic students (years 1, 3, 5, and 6) at a South African institution. The 18-item Patient–Practitioner Orientation Scale (PPOS), with scoring 1–6 on a Likert scale, was used to evaluate the attitude toward PCC by students. Higher scores were representative of more patient-centeredness. Variables were analyzed to assess for associations between variables. Mean PPOS scores were calculated, and reliability and validity were tested using Cronbach α and factor analysis. Results There were 100 respondents (68% response rate). The PPOS showed unsatisfactory reliability in our sample. The mean scores for the overall PPOS were 3.64 (SD = 0.46), the sharing subscale was 2.99 (SD = 0.61), and the caring subscale was 4.29 (SD = 0.58). There were small but suggestive trends noticed in PPOS scores based on age, sex, and year of study. Conclusions Chiropractic students from our university showed a general positive tendency toward PCC with no association between age and year of study. Sex showed some suggestive descriptive trends contrary to findings in other studies. The PPOS showed poor reliability in this study, warranting consideration with its use in similar contexts.

Effects of short-term salinity exposure on haemolymph osmolality, gill morphology and Na+/K+ - ATPase activity in Solenaia oleivora

In order to explore the physiological reaction to hyperosmotic environment, Solenaia oleivora were exposed to 2.23‰ salinity. In 48h, the hemolymph osmolality kept increasing, and the hemolymph protein concentration increased in the first 6h and then decreased significantly, while the free amino acid content increased in the first 24h and then kept stable (P < 0.05). The activity of Na+/K+-ATPase at 0h was significantly higher than other times in most organs except intestine, which was highest at 3h (P < 0.05). The ions concentration were also influenced. The concentration of Na+ rose in haemolymph, axe foot and intestine, but decreased in gill and hepatopancreas. In hemolymph, gill, hepatopancreases and adductor muscle, the K+ concentration was the highest at 0h, while in axe foot and intestine, it showed a positive tendency. The concentration of Cl- in haemolymph, adductor muscle, intestine and axe foot were positively correlated with treatment time, while hepatopancreas showed opposite tendency. High salinity stress caused a difference in the gill histological structure, the gill structure shrunk, the gill lamellas space and shrinking degree showed an enlarging trend with salinity treatment time.

EDUCATIONAL EFFECTIVENESS OF A VIRTUAL DESIGN STUDIO ON ZERO-ENERGY BUILDING DESIGNS: THE CASE OF THE U.S. SOLAR DECATHLON DESIGN CHALLENGE

ABSTRACT Ongoing global architectural agendas span climate change, energy, a carbon-neutral society, human comfort, COVID-19, social justice, and sustainability. An architecture studio allows architecture students to learn how to solve complicated environmental issues through integrated thinking and a design process. The U.S. Department of Energy’s Solar Decathlon Design Challenge enables them to broaden their analytic perspectives on numerous subjects and strengthen their integrated thinking of environmental impacts, resilience, sustainability, and well-being. However, the unprecedented impact of the global COVID-19 pandemic transformed the physical studio-based design education system into an online-based learning environment. Mandatory social distancing by the global COVID-19 pandemic restricted interactive discussions and face-to-face collaborations for the integrated zero-energy building design process, which requires features of architecture, engineering, market analysis, durability and resilience, embodied environmental quality, integrated performance, occupant experience, comfort and environmental quality, energy performance, and presentation. This study emphasizes the educational effectiveness of virtual design studios as a part of the discourse on architectural pedagogy of zero-energy building (ZEB) design through integrated designs, technological theories, and analytic skills. The survey results of ten contests show educational achievement with over 90% of the highest positive tendency in the categories of embodied environmental quality and comfort and environmental quality, whereas the positive tendency of educational achievement in the categories of integrated performance, energy performance, and presentation were lower than 70%. The reason for the low percentage of simulation utilization and integrated performance was the lack of a proper understanding of and experience with ZEB simulations and evaluations for undergraduate students. Although VDS is not an ideal pedagogical system for the iterative design critique process, it can support the learning of the value of architectural education, including integrative design thinking, problem-solving skills, numerical simulation techniques, and communicable identities through online discussions and feedback during the COVID-19 pandemic.

Oceanic Drivers and Empirical Prediction of Interannual Rainfall Variability in Late Summer Over Northeast China

Northeast China (NEC) is located between the subtropical monsoon and temperate-frigid monsoon regions and exhibits two successive rainy seasons with different natures: the northeast cold vortex rainy season in early summer (May–June) and the monsoon rainy season in late summer (July–August). Summer rainfall over NEC (NECR) has a fundamental influence on society, yet its successful seasonal prediction remains a long-term scientific challenge to current dynamical models. The poor NECR prediction skill is partly attributed to the large NECR variability at both the interannual and interdecadal time scales. Here, we focus on the oceanic drivers of the late summer NECR variability and associated physical processes at interannual time scale. Then, we establish an empirical prediction model to predict the interannual variability of summer NECR at one-month lead time (in June). The analysis of observations spanning 40 years (1963–2002) reveals three physically and synergistically influencing predictors of the late summer NECR interannual variability. Above-normal NECR is preceded in the previous spring by (a) warm sea surface temperature (SST) anomalies in the tropical northern Indian Ocean, (b) a positive thermal contrast tendency in the tropical West–East Pacific SST, and (c) a positive tendency of the North Atlantic tripolar SST. These precursors enhance the anomalous low-level anticyclone over the Northwest Pacific and southerly anomalies over NEC in late summer, which are beneficial to enhancing NECR. An empirical prediction model built on these three predictors achieves a forecast temporal correlation coefficient (TCC) skill of 0.72 for 1961–2019, and a 17-year (2003–2019) independent forecast shows a significant TCC skill of 0.70. The skill is substantially higher than that of five state-of-the-art dynamical models and their ensemble mean for 1979–2019 (TCC=0.24). These results suggest that the proposed empirical model is a very meaningful approach for the prediction of NECR, although the dynamical prediction of NECR has considerable room for improvement.

Effects of heterogeneous reactions on tropospheric chemistry: a global simulation with the chemistry–climate model CHASER V4.0

This study uses a chemistry–climate model CHASER (MIROC) to explore the roles of heterogeneous reactions (HRs) in global tropospheric chemistry. Three distinct HRs of N2O5, HO2, and RO2 are considered for surfaces of aerosols and cloud particles. The model simulation is verified with EANET and EMEP stationary observations; R/V Mirai ship-based data; ATom1 aircraft measurements; satellite observations by OMI, ISCCP, and CALIPSO-GOCCP; and reanalysis data JRA55. The heterogeneous chemistry facilitates improvement of model performance with respect to observations for NO2, OH, CO, and O3, especially in the lower troposphere. The calculated effects of heterogeneous reactions cause marked changes in global abundances of O3 (−2.96 %), NOx (−2.19 %), CO (+3.28 %), and global mean CH4 lifetime (+5.91 %). These global effects were contributed mostly by N2O5 uptake onto aerosols in the middle troposphere. At the surface, HO2 uptake gives the largest contributions, with a particularly significant effect in the North Pacific region (−24 % O3, +68 % NOx, +8 % CO, and −70 % OH), mainly attributable to its uptake onto clouds. The RO2 reaction has a small contribution, but its global mean negative effects on O3 and CO are not negligible. In general, the uptakes onto ice crystals and cloud droplets that occur mainly by HO2 and RO2 radicals cause smaller global effects than the aerosol-uptake effects by N2O5 radicals (+1.34 % CH4 lifetime, +1.71 % NOx, −0.56 % O3, +0.63 % CO abundances). Nonlinear responses of tropospheric O3, NOx, and OH to the N2O5 and HO2 uptakes are found in the same modeling framework of this study (R>0.93). Although all HRs showed negative tendencies for OH and O3 levels, the effects of HR(HO2) on the tropospheric abundance of O3 showed a small increment with an increasing loss rate. However, this positive tendency turns to reduction at higher rates (>5 times). Our results demonstrate that the HRs affect not only polluted areas but also remote areas such as the mid-latitude sea boundary layer and upper troposphere. Furthermore, HR(HO2) can bring challenges to pollution reduction efforts because it causes opposite effects between NOx (increase) and surface O3 (decrease).
