Tha Chin River Project: A solution for salt intrusion in the Tha Chin River mouth
No full textThe Tha Chin River is a river in central Thailand, which starts in Chainat province as a branch of the Chao Phraya River and flows into the Gulf of Thailand at about 35 km southwest of Bangkok. The Tha Chin is one of Thailand’s most important rivers and it plays a vital role for the lives of over two million people living in this basin. Near the river mouth, it serves as a traffic route for about 4000 ships, mostly used for fishing, located in the area. More upstream, the river is used for both shrimp farms and fisheries, as well as fruit and flower farming and paddy fields. Al these fields are irrigated using a vast and complex network of increasingly smaller irrigation channels, controlled by water gates. The use of river water is however not limited to irrigation only. Besides the agricultural users, the industrial and domestic users are two other major consumers of water from the Tha Chin. Currently the river basin is experiencing serious problems regarding water quality. One of these problems is the high amount of pollution in the river. Multiple factors (e.g. waste water dump from several sources, oil spillage and water hyacinths) contribute to lower dissolved oxygen levels, higher levels of chemicals and algae blooms. Resulting in considerable damage to the ecosystem in the last decades. Another major water problem is salt intrusion. The tide in the Gulf of Thailand brings saline water into the river. Currently this water is pushed back by increasing the river discharge, which is controlled by the Pho Praya water gate in the Suphanburi Province. However, during the dry season the river discharge is often too low to effectively push back salt water and therefore salinity in the Tha Chin becomes too high. The salt water threatens the agricultural production, it decreases the amount of yearly grown crops or even destroys them complete, causing major economic damage. Additionally, it decreases the river capacity with respect to its function to provide fresh water. One of the major institutions involved in managing and controlling the Tha Chin River is the Royal Irrigation Department (RID). This is a department of the Thai Ministry of Natural Resources \& Environment. The RID is responsible for the development and maintenance of the main irrigation systems. As such, it controls the irrigation network in the Tha Chin Basin. Part of their mission is developing water resources and in their search for solving the salt intrusion problem in the Tha Chin, they asked the TU Delft project team to find with a solution. Two solutions are proposed. The first solution is building a barrier in the river at 12 km upstream from the river mouth. This solution is the only one that can solve the salt intrusions problem, however due to negative experiences in other rivers this solution is likely to encounter much opposition. The second solution is the construction of Balance Islands in front of the river mouth. The principal of this solution is to alter the tidal flow such that saline water flows less into the river while the river discharge is not obstructed. In order to implement this solution further research is needed. Also this solution is not able to solve the salt intrusion problem entirely, but will make the problem less severe.Civil Engineering and GeosciencesHydraulic Engineering / Structural EngineeringMultidisciplinary Project CIE4061-0

The role of the femoral component orientation on dislocations in THA: a systematic review
No full textIntroduction: Dislocation remains a major complication in total hip arthroplasty (THA), in which femoral component orientation is considered a key parameter. New imaging modalities and definitions on femoral component orientation have been introduced, describing orientation in different planes. This study aims to systematically review the relevance of the different orientation parameters on implant stability. Methods: A systematic review was performed according to the PRISMA guidelines to identify articles in the PubMed and EMBASE databases that study the relation between any femoral component orientation parameters and implant stability in primary THA. Results: After screening for inclusion and exclusion criteria and quality assessment, nine articles were included. Definitions to describe the femoral component orientation and methodologies to assess its relevance for implant stability differed greatly, with lack of consensus. Seven retrospective case–control studies reported on the relevance of the transversal plane orientation: Low femoral- or low combined femoral and acetabular anteversion was statistical significantly related with more posterior dislocations, and high femoral- or combined femoral and acetabular anteversion with anterior dislocations in two studies. There were insufficient data on sagittal and coronal component orientation in relation to implant stability. Conclusion: Because of incomparable definitions, limited quality and heterogeneity in methodology of the included studies, there is only weak evidence that the degree of transverse component version is related with implant stability in primary THA. Recommendations about the optimal orientation of the femoral component in all three anatomical planes cannot be provided. Future studies should uniformly define the three-dimensional orientation of the femoral component and systematically describe implant stability.Biomaterials & Tissue Biomechanic
Accuracy of Positioning Custom Triflange Acetabular Components in THA Revision and Tumor Resection Surgery – A 3D-CT Assessment Stud
No full textIntroduction In recent years, there has been an increasing interest in custom triflange acetabular components (CTAC) for revision and oncological surgery. The aim of this study was to evaluate the surgical accuracy of positioning CTACs in patients receiving either total hip arthroplasty (THA) revision or tumor resection surgery, using a novel 3D analyzing technique. Method This retrospective cohort study included 35 patients (27 tumor and 8 THA revision cases), between February 2017 and March 2021. All patients received a CTAC. The planned and achieved implant position were assessed by means of a developed semi-automatic 3D-CT assessment method. The primary outcomes were the cup angles described as inclination, anteversion and cup rotation, and the translation of center of rotation (COR), pubic flange, ischial flange and ilium flange in three planes. Results The mean deviation, between planned and achieved, in inclination was 0.5° (SD: 3.9°), in anteversion 1.2° (SD: 6.1°) and in cup rotation 0.6° (SD: 3.2°). The mean deviation in COR in the sagittal plane was -0.8 mm (SD: 3.2), in the coronal plane -0.4 mm (SD: 6.3) and in the axial plane 0,6 mm (SD: 6,1). Translation of the ischial flange showed the largest aberration (median absolute value: 7.0 mm), followed by the pubic flange (6.4 mm) and the ilium flange (5.3 mm). Discussion A semi-automatic method to analyze the 3D position of CTAC was presented in this study. The results show good agreement between the planned and achieved implant position in patients receiving THA revision or tumor resection surgery. 89% of the components in this study were accurately positioned according to our criteria.Technical Medicine | Imaging and Interventio
Shook one anxiety playing tricks on me
No full text"Charlamagne Tha God, New York Times bestselling author of Black Privilege and cohost of Power 105.1's The Breakfast Club, reveals his blueprint for breaking free from your fears and anxiety to reach that elusive next level of success. Fear is holding you back. It's time to turn the tables and channel your fears to actually fuel your success. Being "shook" is more than a rap lyric for Charlamagne, it's his mission to overcome. While it may seem like he is ahead of the game and should have nothing to worry about, he is still plagued by anxieties...fear of being weak; fear of being a bad dad; fear of being a worse husband; and ultimately, fear of failure. Shook One chronicles his journey to beat back those fears and empowers you to no longer be held back from your potential. Shook One details the ways anxiety has been a driving force in Charlamagne's life since childhood. For many years, he stressed over what he thought were personal shortcomings: being unpopular in school, potential rejection by women, being ugly, and worst of all, falling into the life of stagnation or crime that caught up so many of his friends and family in his hometown of Moncks Corner, South Carolina. Even after achieving national prominence as a radio personality, Charlamagne still found himself paralyzed by thoughts that he wouldn't be able to take his career to the next level. But now, in Shook One, he is working through these problems with help from mentors, guests on his show, and therapy. He knows therapy and showing weakness are anxiety producing in the black community, but this is one of the reasons he wants to own his truth...to clear a path for others in hopes that they won't feel shame while dealing openly with their mental health"..."Charlamagne Tha God, New York Times bestselling author of Black Privilege and cohost of Power 105.1's The Breakfast Club, reveals his blueprint for breaking free from your fears and anxiety to reach that elusive next level of success"..
Current Evidence for Spinopelvic Characteristics Influencing Total Hip Arthroplasty Dislocation Risk
No full textBACKGROUND: Decreased pelvic mobility and pelvic retroversion may result from spinal degeneration and lead to changes in the orientation of the acetabular implant after total hip arthroplasty (THA). While multiple patient and surgery-related factors contribute to THA dislocations, there is increasing evidence that sagittal spinopelvic dynamics are relevant for THA stability. The aim of this systematic review was to assess the relationship between previously described sagittal spinopelvic characteristics and implant dislocations after primary THA. METHODS: A comprehensive literature search in the PubMed and Embase databases was conducted for studies reporting on spinopelvic morphology, alignment, pathology, or surgery and THA dislocations. Risk of bias was assessed using the MINORS criteria. Because of high heterogeneity in study methodology, a synthesis of best evidence was performed. Odds ratios (ORs), relative risks (RRs), and effect sizes (g) were calculated. RESULTS: Fifteen studies (1,007,900 THAs) with quality scores of 15 to 23 out of 24 were included. Nine different spinopelvic alignment parameters (8 studies, g = 0.14 to 2.02), spinal pathology (2 studies, OR = 1.9 to 29.2), and previous spinal fusion surgery (8 studies, OR = 1.59 to 23.7, RR = 3.0) were found to be related to THA dislocation. Conflicting results were found for another sagittal pelvic morphology parameter, pelvic incidence. CONCLUSIONS: Several sagittal spinopelvic patient characteristics were found to be related to THA dislocation, and the associated risks were greater than for other patient and surgery-related factors. Future research is needed to determine which of those characteristics and parameters should be taken into account in patients undergoing primary THA. LEVEL OF EVIDENCE: Prognostic Level III.
