Custom Made Fenestrated Stent Graft Collapse after Thoracic Endovascular Aortic Repair: A Case Report

We present a case of stent graft collapse after performing thoracic endovascular aortic repair with a custom-made fenestrated stent graft. The patient was a 70-year-old woman with an asymptomatic aneurysm of the distal aortic arch, and thoracic endovascular aortic repair was performed. The patient showed a blood pressure difference between the left arm and the right arm on postoperative day (POD) 17 prompting the performance of a chest computed tomography scan which revealed stent graft collapse. She then underwent staged debranching of thoracic endovascular aortic repair. Stent graft collapse is a rare but well-described complication of thoracic endovascular repair. Therefore, patients who undergo such a procedure should be carefully monitored for signs and symptoms, which suggest the possibility of stent collapse.

Computer-aided Design and Custom-made Guide in Corrective Osteotomy for Complex Femoral Deformity

Summary： Preoperative planning of corrective osteotomy with traditional radiography has limitations in regards to determining the ideal osteotomy location and orientation in three-dimensional femoral de- formities. Though a successful operation can be planned preoperatively, intraoperative contingencies might adhere to the procedural plan in the performance of operation. To efficiently perform a planned procedure, proposed is a design to implement three-dimensional reconstruction photography, based on computer-tomography （CT） scan. A custom-made guide was designed to navigate the osteotomy as planned, and additionally, a personalized intramedullary nail was used for fixation after osteotomy. Three-dimensional （3D） photography of deformed femur was established based on the CT dataset and transferred into 3D photography processing software for further planning. Osteotomy planes were de- signed and adjusted at deformity sites to correct the 3D deformities. The methodology of a custom-made osteotomy guide was introduced in femoral corrective osteotomy, for the first time, to navigate the op- eration as planned. After the virtual osteotomy and reduction of bone segments, the parameters of a custom-made intramedullary nail were measured for manufacturing. Findings Virtual operation in computer shows complete correction of the 3D deformity. The osteotomy guide, obtained by rapid-prototyping techniques, navigates mimicking surgery on rapid-prototyping model of the involved femur as planned. Internal fixation was achieved using the custom-made intramedullary nail. Interpreta- tion three-dimensional visualization introduces an advantage in preoperative planning for corrective os- teotomy of 3D femoral deformity, and the custom-made osteotomy guide is crucial to realize such a de- liberate plan during the actual procedures. The internal fixator, such as an intramedullary nail, can be modified or personalized for fixation in unique cases.

Numerical modeling of deep-seated landslides interacting with man-made structures

This paper describes the interaction between deep-seated landslides and man-made structures such as dams, penstocks, viaducts, and tunnels. Selected case studies are reported first with the intent to gain insights into the complexities associated with the interaction of these structures with deep-seated landslides(generally referred to as deep-seated gravity slope deformations, DSGSDs). The main features, which characterize these landslides, are mentioned together with the interaction problems encountered in each case. Given the main objective of this paper, the numerical modeling methods adopted are outlined as means for increase in the understanding of the interaction problems being investigated. With the above in mind, the attention moves to an important and unique case history dealing with the interaction of a large-size twin-tunnel excavated with an earth pressure balance(EPB)tunnel boring machine(TBM) and a deep-seated landslide, which was reactivated due to the stress changes induced by tunnel excavation in landslide shear zone. The geological and geotechnical conditions are described together with the available monitoring data on the landslide movements, based on the advanced and conventional monitoring tools used. Numerical modeling is illustrated as an aid to back-analyze the monitored surface and subsurface deformations and to assist in finding the appropriate engineering solution for putting the tunnel into service and as a follow-up means for future understanding and control of the interaction problems. The simulation is based on a novel time-dependent model representing the landslide behavior.

Tailor-Made Mesh for Pelvic Organ Prolapses: Correlation between Patient’s Height and Mesh Size

Tension-free vaginal mesh (TVM) surgery is a common and minimally invasive procedure for pelvic organ prolapses. Since commercial kits are not readily available in Japan, we have planned tailor-made mesh by information of each patient before every TVM surgery. The aim of this report is to inform methods to design mesh for individual patients with pelvic organ prolapses. We also investigated the correlations among mesh size and height, weight, and body mass index (BMI). Before the operation, we obtained a KUB (abdominal X-ray). Three factors were measured from this X-ray: the first was the distance between the bilateral ischial spine, the second was the distance between the obturator foramen, and the third was the length of the arcus tendineus fascia pelvis (ATFP). These three factors always should be considered for designing of mesh. The correlations among the bilateral ischial spine distance, obturator foramen distance, ATFP length, height, weight, and BMI were assessed using the Pearson correlation coefficient. Although these three factors described above are necessary to design a mesh for individual patients, the bilateral ischial spine and obturator foramen distance correlated with the height of the patient. On the other hand, since the length of ATFP differs in each patient and is not correlated with height, we should consider this length when we design the mesh. Well-designed, tailor-made mesh will probably fit each pelvic organ prolapsed patient very well.

Considering and comparing regeneration in natural and man-made stands in northern Iran

In this study the regeneration diversity of Syahkal forests afforestated and natural stands in north of Iran was studied and compared from the point of view of evenness and diversity index. In order to accomplish this study two natural and man-made stands that almost are located in the same height above the sea level were chosen. The area of each stand was 30 ha and the inventory was done by the random-systematic method with a 5R land measurement （500 m2） selected. Also, in order to study the regeneration in the center of each sample piece 125 square meters micro plots were formed. The results show that regeneration diversity index in natural stands is more than that in man-made stands which in this case Mc-Arthur index with 2.41 has the most amount while Simpson index with 0.543 has the least amount. But the evenness indexes in man-made stands are more than that in natural stand which the main reason is the purity of the man-made stand.

Effectiveness of a Custom-Made Temporary Obturator after Bilateral Total Maxillectomy

Large oro-antral communication, associated with total maxillectomy, may lead speech and/or swallowing dysfunction. These surgical defects are packed with obuturator or prosthesis following surgery;however, achieving retention and stability is dependent on anatomical conditions. A 68-year-old Japanese female with large oro-antral communication arising because of bilateral total maxillectomy was referred for evaluating application of obturator. The temporary obturator was constructed as underlying 3 mm thick and covereing 1.5 - 2 mm thick ethylene vinyl acetate sheet (EVA). These two sheets formed the flexible hollow bulb portion, which aided retention and stability by engaging the undercut portion of the surgical defect. For the patients who have difficulty anatomical features for conventional prosthesis, this type of temporary obturator made with EVA sheets could be an effective solution in the early postoperative period.

Simultaneous removal of cesium and strontium using a photosynthetic bacterium, <i>Rhodobacter sphaeroides</i>SSI immobilized on porous ceramic made from waste glass

This study investigated practical and simultaneous removal of cesium (Cs, initial concentration of 5 mg/L) and strontium (Sr, initial concentration of 5 mg/L) using a photosynthetic bacterium, Rhodobacter sphaeroides SSI, immobilized on recovery-type porous ceramic made from glass waste. When 4 - 8 pieces /L of SSI immobilized ceramic were added to synthetic sewage wastewater containing glucose, almost 100% of Cs and 57% - 61% removal of Sr was observed after 3 day’s aeration treatment. The high potassium (K) concentration in wastewater suppressed Cs removal, but did not affect Sr removal. Other substrates such as lactic, acetic, and propionic acids were useful for Cs and Sr removal. But, removal efficiencies were lower than about 50%. When the practical outdoor removal experiment carried out using1 m3 vessel, almost 100% of Cs and 51% of Sr were removed like a laboratory experiment after 3 day’s aerobic treatment. After treatment, the SSI immobilized ceramic was recovered easily from water using an electromagnet. This SSI immobilized ceramic seem to remove radioactive Cs and Sr from water environments of Fukushima,Japan.

Implementation of Corporate Social Responsibility in the Ready-Made Garment Industry of Bangladesh in Order to Achieve Sustainable Development Goals: A Study on Bangladeshi Garment Manufacturers

The Ready-Made Garment (RMG) sector has played the most momentous role for the economic development of Bangladesh. To achieve the culmination, this labor-intensive industry needs to go through sustainable practices with the adoption of Corporate Social Responsibility (CSR) in its garment manufacturing chain. CSR, being a fast-developing phenomenon in industrial arena, is drawing the attention of world-renowned apparel buyers working with Bangladesh. After a few tragic occurrences, for instance, Rana Plaza collapse & Tazreen Fashion fire, the reputation of the RMG sector of Bangladesh has been somewhat blemished. Presently, this scenario is being changed since a considerable number of Bangladeshi garment producers have adopted CSR practices spending a huge sum of money. This study shows the current status of sustainable development through the implementation of CSR practices in the RMG industry of Bangladesh.

Cranioplasty of Calvarial Skull Defects: A Comparative Study between Using Three Dimensional Custom-Made Cranioprostheses versus Hand-Made Bone Cement in Restoring Skull Configuration

Introduction: Cranioplasty is the surgical repair of a bony defect or deformity in the skull that is caused after cranial surgery or trauma. It carries cosmetic and protective benefits. Many types of materials are allowed. The subject of this study is to compare the outcome of two different manufacturing processes in reconstruction of calvarial skull defects by using 3D custom-made cranioprostheses versus hand-made bone cement implants. Patient and Methods: This is a prospective comparative study conducted on 20 patients of calvarial skull defects of different etiologies, sites and sizes, admitted in the neurosurgical departments of Cairo and Fayoum Universities in the period from August 2017 to February 2018. Patients are divided into two study groups: (group 1) 10 patients operated upon by 3D custom-made implant;(group 2) operated upon by hand-made bone cement implant. Statistical Analysis Used: Mann-Whitney test and Chi-square test. Results: Craniotomy using 3D custom-made implants gives better results than using bone cement in the functional restoration of skull shape and cranial protection with shorter operative time and less rate of postoperative complications. There is no statistically significant difference between the two study groups regarding cosmetic outcome. Conclusion: 3D custom-made implant is recommended for large and complex skull defects. Further and large studies might be needed.

Ecology and Fish Biodiversity of Man-Made Lakes of Southern Benin (West Africa): Implications for Species Conservation and Fisheries Management

Man-made lakes are alternative and potential habitats for biodiversity conservation, fisheries and extensive aquaculture. We investigated the ecology and the fish community structure of two (2) sand-dragged man-made lakes, Lake Ahozon and Lake Bewacodji of Southern Benin, with implications for species conservation, fisheries management and aquaculture valorization. From August 2014 to July 2015, habitats conditions were evaluated and fishes were sampled monthly with seine, cast net, experimental gill net and hooks in the open water and aquatic vegetation habitats of both lakes. Overall, the water quality of Lake Ahozon was globally favorable for the growth and the survival of the fish resources whereas Lake Bewacodji exhibited a poor water quality indicated mainly by an acid pH (mean: 6.32 ± 0.58) and low dissolved oxygen concentrations (mean: 3.52 ± 1.25 mg/l) caused by dense floating plants, Nymphea sp mainly and huge daily dumping of domestic wastes. The study revealed low species richness, d = 5.89 and d = 3.87, and low species diversity, H’ = 0.76 and H’ = 0.48 for Lakes Ahozon and Bewacodji, respectively, with Lake Ahozon more diverse than Lake Bewacodji. The fish community of Lake Ahozon comprised six (6) species, 3 cichlids Sarotherodon galilaeus, Oreochromis niloticus and Tilapia guineensis, the silver catfish, Chrysichthys nigrodigitatus (Claroteidae), the African bonytongue, Heterotis niloticus (Osteoglossidae), and the African catfish, Clarias gariepinus (Clariidae). Numerically, S. galilaeus dominated Lake Ahozon and made 85.21% of the sample. In Lake Bewacodji, the fish composition comprised four (4) species, Sarotherodon galilaeus multifasciatus, the dominant species making numerically 91.58% of the total sample, T. guineensis, C. gariepinus and C. nigrodigitatus. With regard to trophic structure, the fish assemblages of both lakes were numerically dominated by planktinovores/ detritivores, mainly S. galilaeus, O. niloticus, T. guineensis and C. nigrodigitatus making together 99.46% of Lake Ahozon fish community, and S. galilaeus multifasciatus, T. guineensis and C. nigrodigitatus accounting together for about 98.59% of Lake Bewacodji. In Lake Ahozon, standard length (SL) frequencies histograms showed an unimodal size distribution for H. niloticus, the nile tilapia O. niloticus and C. gariepinus whereas the two cichlids, S. galilaeus and T. guineensis exhibited a bimodal size distribution. In Lake Bewacodji, S. galilaeus multifasciatus, C. nigrodigitatus and C. gariepinus exhibited an unimodal size distribution. A sustainable exploitation of both man-made lakes requires the implementation of an integrated management scheme which should include habitat restoration and protection plan, fisheries/aquacultural valorization, ecological sound agriculture/ecotourism and environmental monitoring.

Study of Decoherence of Entangled States Made up of Two Basic States in a Linear Chain of Three Qubits

Using Lindblad approach to study decoherence of quantum systems, we study the decoherence and decay of entangled states, formed by two basic states of a chain of thee qubits. We look on these states for a possible regular dependence on their decay as a function of their energy separation between the basic states under different types of environments. We didn’t find regular or significant dependence on this energy separation for the type of environment considered.

WATER QUALITY STUDIES IN MALAYSIAN DISUSED MAN MADE LAKES FOR SUITABILITY OF AN AQUACULTURE PROJECT

A study has been conducted on the status of water quality in two disused man made lakes, which have potential for cage aquaculture project. This study highlights the quality of water analyzed with reference to various physical-chemical parameters in two selected lakes and their suitability for fish farming. A number of parameters were measured including the amount of NH_ 3 -N, NO_ 3 -N, NO_ 2 -N and total phosphorus while in-situ measurement including DO, pH, temperature, conductivity, TDS and Secchi disk visibility. Beside the physical-chemical of water, the location, morphometry and climate conditions were also investigated. The chemical data analyzed for six months indicated that Lake A and Lake B are characterized by relatively high DO, slightly neutral pH and low TSS. The concentration of NH_ 3 -N and NO_ 2 -N was very low (0.058 mg/L and 0.04 mg/L, respectively) and total phosphorus was usually in low concentration and sometimes would seem negligible. Besides, NO_ 3 -N occurred in slightly higher concentration ( 1.75 mg/L ). Results obtained indicated that the study site has high potentiality for development of inland fisheries practices.
