description: Background Perivascular epithelial cell tumors (PEComas) are a family of rare mesenchymal neoplasms which share cellular, immunohistochemical and ultrastructural characteristics but are found in different visceral and soft tissue sites. PEComas of the pancreas are extremely rare neoplasms. Case report We describe a 49-year-old male who was incidentally diagnosed with a pancreatic mass. Endoscopic ultrasound-guided biopsy suggested a PEComa. An uneventful pylorus-preserving pancreaticoduodenectomy was thus performed. The tumor was a solid well-circumscribed mass in the pancreatic head with dilatation of the main pancreatic duct. Histopathology revealed a well-circumscribed and vascularized neoplasm, measuring 32x27x30 mm, composed of epithelioid smooth muscle cells with clear cytoplasm rich in glycogen. The tumor exhibited immunoreactivity to alpha-smooth muscle actin and to melanoma-associated antigen HMB-45. Conclusions Although rare, pancreatic PEComas should be included in the differential diagnosis of a pancreatic mass. Currently, the paucity of cases published makes it impossible to predict the behavior and prognosis of these tumors or to advocate an optimal therapy.

description: Abstract
Mikael P. Sitanggang. 2021. Dissertation of the Doctoral Study Program in Law, Diponegoro University, Semarang. Law Enforcement against Illegal Logging in Indonesia through efforts to increase the role of the Police. The purpose of this study is to analyze: 1) What is the role of the police in handling illegal logging in Indonesia? 2) What is the criminal law policy in handling illegal logging in Indonesia. The research method used is empirical juridical with a statutory approach, concept approach, and case studies. The results showed that: 1) The implementation of forest protection and management to prevent forest destruction from illegal logging practices by irresponsible humans requires guard and supervision by authorized officials, in this case the Forestry Police (Polhut). 2) In various legal literature, the crime of illegal logging is a criminal crime that has the nature of an extraordinary crime (extra ordinary crime). Illegal logging is classified as a crime that directly violates Law No. 23 of 1997, concerning Environmental Conservation. Thus, police firmness is needed in applying criminal justice to individuals or groups involved in Illegal Logging.

description: Transport measurements in ramp-type junctions of $YBa_2Cu_3O_y-SrRuO_3-YBa_2Cu_3O_y$ with $T_c$ values of either 80-90 K or 60-70 K are reported. In both type of junctions but without a barrier ("shorts"), the supercurrent densities at 4.2 K reached 7.5 and 3.5 MA/cm$^2$, respectively, indicating the high quality of the fabrication process. Plots of the critical current versus thickness of the ferromagnetic barrier at 4.2 K show exponential decays with decay lengths of 1.1 nm for the 90 K phase and 1.4 nm for the 60 K phase, which are much shorter than the relevant coherence lengths $ξ_F\sim 5-6$ nm or $ξ_N\sim$16 nm of $SrRuO_3$. We thus conclude that there is no dominant proximity induced triplet superconductivity in the ferromagnet in our junctions.

description: Abstract
Legal Problems of the Authority of the Ombudsman Institution in the Constitutional System of the Republic of Indonesia. The purpose of this study is to analyze: What is the position of the Ombudsman of the Republic of Indonesia in the constitutional system of the Republic of Indonesia? How is the Ombudsman of the Republic of Indonesia in the authority of law enforcement in Indonesia. The research method used is empirical juridical with a statutory approach, concept approach, and case studies. The results showed that: 1) The position of the Ombudsman of the Republic of Indonesia in the constitutional system of the Republic of Indonesia is that the Ombudsman is one of the additional  state institutions or secondary or extra auxiliary institutions, namely state institutions formed outside the constitution in this case the 1945 Constitution. Thus, the Ombudsman answers the demands of the community for the creation of democratic principles in every administration of government through an accountable, independent, trustworthy and free from political interference. 2)  The non-regulation of the Ombudsman in the constitution in this case the Constitution creates a loophole for the position of the Ombudsman in the constitutional system of the Republic of Indonesia that there is no guarantee that the Ombudsman institution as a state institution is permanent and not easily dissolved, except by amending the State Constitution of 1945. In relation to the duties and authorities of the Ombudsman, the Ombudsman's recommendations are more than ordinary advice to Government Officials or State Administrators on what should be done to improve the services complained by the community, both case-by-case and systematic. So  the Ombudsman's recommendation is not a legally binding court decision, it does not mean that it can be simply ignored, because there are other binding mechanisms that protect the Ombudsman's recommendation, besides moral binding, namely political attractiveness

description: In this paper we explicitly obtain the leading corrections to the SU(N) N=2 prepotential due to stringy instantons both in flat space-time and in the presence of a non-trivial graviphoton background field. We show that the stringy corrections to the prepotential are expressible in terms of the elementary symmetric polynomials. For N>2 the theory is not conformal; we discuss the introduction of an explicit dependence on the string scale α' in the low-energy effective action through the stringy non-perturbative sector.

description: Let A be an associative algebra with identity over a field k. An atomistic subsemiring R of the lattice of subspaces of A, endowed with the natural product, is a subsemiring which is a closed atomistic sublattice. When R has no zero divisors, the set of atoms of R is endowed with a multivalued product. We introduce an equivalence relation on the set of atoms such that the quotient set with the induced product is a monoid, called the condensation monoid. Under suitable hypotheses on R, we show that this monoid is a group and the class of k1_A is the set of atoms of a subalgebra of A called the focal subalgebra. This construction can be iterated to obtain higher condensation groups and focal subalgebras. We apply these results to G-algebras for G a group; in particular, we use them to define new invariants for finite-dimensional irreducible projective representations.

A millimeter-long waveguide is suspended and tapered on the chip over a length of 25 μm to evanescently couple to high Q optical whispering gallery modes of a GaAs disk. The critical coupling regime is obtained both by varying the disk/guide gap distance and the width of the suspended nanoscale taper. The experimental results are in good agreement with predictions from the coupled mode theory.

description: Context Pancreaticobronchial fistula is a rare complication of severe pancreatitis. Various diagnostic methods have been described previously. Case report The presentation, diagnostic methods, management and 5-year follow-up of a 40-year-old woman with severe gallstone induced pancreatitis complicated by a pancreaticobronchial fistula were reviewed. Diagnosis was made on the endotracheal intubation when amylase rich-fluid was drained via the tube and confirmed by CT scanning. Successful management was achieved by an open pancreatic necrosectomy, during which air bubbles were seen emerging from the pancreatic collection which supported the diagnosis of the fistula. Five-year follow-up did not reveal any complications. Conclusions Pancreaticobronchial fistulas have the potential to cause severe respiratory complications and mortality. Awareness of this condition is important in the treatment of complicated cases of pancreatitis.

description: Context Primary adenocarcinoma of the duodenum is a rare digestive malignancy which is commonly treated by radical surgical resection, pancreaticoduodenectomy being the technique of choice. Complete tumor resection obtaining free margins should be the standard of treatment for primary adenocarcinoma of the duodenum. Segmental duodenal resection is an appropriate operation for selected cases of primary adenocarcinoma of the duodenum of the 3rd and 4th portions of the duodenum. Case report We present the case of a 67-year-old woman suffering from an infra-ampullary large villous polypoid mass affecting the 3rd portion of the duodenum. Multiple endoscopic biopsies did not disclose any malignancy, and abdominal CT and endoscopic ultrasound found no extraduodenal involvement. A 3rd and 4th portion pancreas-sparing duodenectomy was carried out using a totally laparoscopic approach. Intra-operatory duodenoscopy was done to safeguard the papilla of Vater. Recovery was uneventful and the patient was discharged on the 7th postoperative day. The final diagnosis was primary adenocarcinoma of the duodenum (free resection margins). After forty-five months of follow-up, the patient is free of disease. Conclusions We recommend this procedure for treatment of an infra-ampullary benign and pre-malignant duodenal pathology; it can also be a treatment option and an alternative to a pancreaticoduodenectomy in very selected cases of tumors confined to the duodenum. Expertise in both pancreatic surgery and laparoscopic techniques is required.

description: Abstract
Legal Review of Coastal Waste Management in Improving Community Economy. How can current regulations on beach waste management not improve people's economies? How is the legal construction in coastal waste management in improving the economy? The research method used is empirical juridical with a statutory approach, concept approach, and case studies. The results showed that: 1) The government is responsible for adequate recollection and disposal of waste from settlements. However, because there are other things that must be prioritized in development in the regions and the lack of supporting funds for the operationalization of waste management, making in some areas this waste management activity is not as expected. This is further strengthened by the lack of application of the principle that those who produce goods must manage waste from these goods. Of course, in this case, public legal awareness related to waste management and utilizing waste into goods of economic value is needed. By doing so, it will help in encouraging economic improvement in the community. 2) According to Law Number 18 of 2008 concerning waste management, states that waste is a national problem so that its management needs to be carried out comprehensively and integrated from upstream to downstream in order to provide economic benefits, healthy for the community, and safe for the environment, and can change community behavior. Presidential Regulation of the Republic of Indonesia No. 97 of 2017 concerning National Policies and Strategies for Household Waste Management and Similar Household Waste, targets a 30% waste reduction by 2025 through 3R (Reduce, Reuse and Recycle). One solution in waste or waste management can be the existence of a waste bank. Through waste banks, waste management needs to be carried out in order to benefit the community economically. Not only in the economic sector, waste banks also aim to educate so that people become aware and more creative. The waste bank also aims to provide a pattern of good behavior in managing waste so that people do not easily dispose of waste anywhere.
Making sense of the bizarre behaviour of horizons in the McVittie spacetime

description: The bizarre behaviour of the apparent (black hole and cosmological) horizons of the McVittie spacetime is discussed using, as an analogy, the Schwarzschild-de Sitter-Kottler spacetime (which is a special case of McVittie anyway). For a dust-dominated "background" universe, a black hole cannot exist at early times because its (apparent) horizon would be larger than the cosmological(apparent) horizon. A phantom-dominated "background" universe causes this situation, and the horizon behaviour, to be time-reversed.

description: We present transverse momentum distributions of inclusive charged particles and identified hadrons in $pp$ and Pb--Pb collisions at $\rs= 2.76$ TeV, measured by ALICE at the LHC. The Pb--Pb data are presented in intervals of collision centrality and cover transverse momenta up to 50 GeV/$c$. Nuclear medium effects are studied in terms of the nuclear modification factor \raa. The results indicate a strong suppression of high-$p_T$ particles in Pb--Pb collisions, consistent with a large energy loss of hard-scattered partons in the hot, dense and long-lived medium created at the LHC. We compare the preliminary results for inclusive charged particles to previous results from RHIC and calculations from energy loss models. Furthermore, we compare the nuclear modification factors of inclusive charged particles to those of identified $π^0$, $π^{\pm}$, K$^0_s$, and $Λ$.

description: Objective: To know the feasibility of applying a model for predicting the risk of preeclampia in a second-level healthcare facility in Ecuador. Methods: Retrospective study of 304 patients with singleton pregnancy in which anthropometric, clinical and biophysical data from prenatal consultation were collected between 11 to 136 weeks from August 2018 to August 2019, to perform an external validation of the preeclampsia risk prediction algorithm of the Hospital Clinic de Barcelona. Results: A total of 26 patients with a high risk screening developed preeclampsia of which 24 (93%) were late-onset. The sample area under the model curve was 0.92 (95% CI). At the cut-off point 0.75 (3/4) of the late-onset preeclampsia risk prediction algorithm from hospital clinic in Barcelona, the detection rate obtained in patients at the Outpatient Surgical Clinical Center Hospital de Día Norte Tarqui, was 88.46%, with a false positive rate of 8.64%. In addition the specificity is 91.37%, the PPV 48.94% and the PNV 98.83%. Conclusion: The combination of clinical parameters, mean blood pressure and the average pulsat rate of the uterine arteries is useful for predicting preeclampsia in the first trimester. The use of the predictive algorithm of the Hospital Clinic of Barcelona is feasible to use it in this unit.

description: We report on a detailed study of the water maser kinematics and radio continuum emission toward the most massive and young object in the star-forming region AFGL 2591. Our analysis shows at least two spatial scales of multiple star formation, one projected across 0.1 pc on the sky and another one at about 2000 AU from a ZAMS star of about 38 Solar masses. This young stellar object drives a powerful jet- and wind-driven outflow system with the water masers associated to the outflow walls, previously detected as a limb-brightened cavity in the NIR band. At about 1300 AU to the north of this object a younger protostar drives two bow shocks, outlined by arc-like water maser emission, at 200 AU either side of the source. We have traced the velocity profile of the gas that expands along these arc-like maser structures and compared it with the jet-driven outflow model. This analysis suggests that the ambient medium around the northern protostar is swept up by a jet-driven shock (>66 km/s) and perhaps a lower-velocity (~10 km/s) wind with an opening angle of about 20 degrees from the jet axis.

description: In order to perform high resolution astrometry of the solar diameter from the ground, through the observations of eclipses, the study of the limb darkening profile is described. Knowing the profile of the solar limb is useful both to monitor the solar radius over time, and to define the oblateness, which is interesting for the classical tests of general relativity. The Limb Darkening Function (LDF) is studied in order to find the inflexion point, to which the measurements of the solar diameter are referred. The proposed method is applied to the videos of the annular eclipse in January, 15, 2010. This new method might solve the ambiguity of some eclipse obervations made with different instruments, where the measured solar diameter was clearly dependent on the aperture of the telescope and on the density of the filter used.

description: Pancreas cancer has the worst prognosis of any solid tumor but is potentially treatable if it is diagnosed at an early stage. Thus there is critical interest in delineating clinical and molecular markers of incipient disease. The currently available biomarker, CA 19-9, has an inadequate sensitivity and specificity to achieve this objective. Diabetes mellitus, tobacco use, and chronic pancreatitis are associated with pancreas cancer. However, screening is currently only recommended in those with hereditary pancreatitis and genetic syndromes which predispose to cancer. Ongoing work to identify early markers of pancreas cancer consists of high throughput discovery methods including gene arrays and proteomics as well as hypothesis driven methods. While several promising candidates have been identified none has yet been convincingly proven to be better than CA 19-9. New methods including endoscopic ultrasound are improving detection of pancreas cancer and are being used to acquire tissue for biomarker discovery.

description: Abstract
The basic construction of the legal relationship between the parties in leasing financing is viewed from the level of regulation and theory. The purpose of this study is to analyze: a. To what extent is Leasing financing able to provide benefits as an alternative to company financing in the form of providing capital goods?; b. How far is the government's attention in providing regulations in the field of corporate financing in the form of Leasing?; c. How is the basic construction of the legal relationship between the parties built with practical regulations made by the government, how is it studied in theoretical aspects? The research method used is empirical juridical with a statutory approach, concept approach, and case studies. The results showed that: a) in general, leasing means financing equipment/capital goods to be used in the production process of a company, either directly or indirectly. Leasing is a financing activity through the provision of capital goods to be used by a company (debtor or lessee) for a certain period of time, and Leasing is also based on periodic financing accompanied or without the right of choice from the company to buy the capital goods concerned to extend the Leasing  periodIt is based on a mutually agreed residual value. b) Leasing has received attention from the Indonesian government. This is evidenced by the issuance of the Civil Code and the Joint Decree of Three Ministers: Minister of Finance, Minister of Trade and Minister of Industry in 1974 concerning Leasing activities. C) The legal relationship between the lessor, supplier and lessee is that the lessor provides the cost of purchasing goods in cash to the supplier. The supplier delivers the goods to the lessee. After the lessee acquires the goods, he makes a lease payment to the lessor. Meanwhile, regarding the mechanism so that legal relations occur between the parties, namely lessors, lessees, and suppliers

The electrons' properties are calculated by a Green's function's equation of motion approach while the magnetization of the local moments is determined by a minimization of the free energy. As results we present magnetic phase diagrams and the interlayer exchange over a broad parameter range. Additionally we can calculate the transition temperatures for different alignments of the ferromagnetic layers' magnetizations.

description: Context Non-operative strategies are gaining preference in the management of patients with severe acute pancreatitis. Objective The present study was undertaken to evaluate the efficacy of a non-operative approach, including percutaneous drainage, in the management of severe acute pancreatitis. Design Prospective study. Setting Tertiary care centre in India. Patients Fifty consecutive patients with severe acute pancreatitis were managed in an intensive care unit. Interventions The patients were initially managed conservatively. Those with 5 cm, or more, of fluid collection having fever, leukocytosis or organ failure underwent percutaneous catheter drainage using a 10 Fr catheter. Those not responding underwent a necrosectomy. Depending on the outcome of their supportive care, the patients were divided into three groups: those responding to intensive care, those needing percutaneous catheter drainage and those requiring surgical intervention. Twelve patients were managed conservatively (Group 1) while 24 underwent percutaneous catheter drainage (Group 2), 9 of whom were not operated (Group 2a) and 15 of whom underwent necrosectomy (Group 2b). Fourteen patients were operated on directly (Group 3). Main outcome measures Hospital stay, intensive care unit stay, and mortality. Results Among patients requiring surgery, the patients in Group 2b had a shorter intensive care unit stay (22.1±11.1 days) as compared to the patients in Group 3 (25.0±15.6 days) and a longer interval to surgery, 30.7±8.9 days versus 25.4±8.5 days. However, these differences did not reach statistical significance (P=0.705 and P=0.133, respectively). The two groups did not differ in terms of mortality (5/15 versus 3/14; P=0.682). Conclusion The use of percutaneous catheter drainage helped avoid or delay surgery in two-fifths of the patients with severe acute pancreatitis.

description: Context Individuals with suspected malignant biliary obstruction commonly undergo ERCP for drainage and tissue sampling via biliary brushings. EUS with EUS-FNA facilitates staging and potentially more accurate tissue sampling. Objective The aim is to compare the diagnostic performance of EUS-FNA and ERCP with biliary brushings (ERCP-BB) in the diagnosis of pancreatobiliary carcinoma and the utility of combining the two procedures under conscious sedation. Design Retrospective analysis of a prospectively maintained database. Patients Thirty-seven patients with suspected malignant obstructive jaundice underwent 39 paired procedures, either combined (n=22) or within a few days (n=17). Results Using strict cytological criteria the sensitivity of EUS-FNA in the diagnosis of malignancy was 52.9% (95% CI: 35.1-70.2%) versus 29.4% (95% CI: 15.1-47.5%) for ERCP-BB. Combining the two tests improved sensitivity to 64.7% (95% CI: 46.5-80.3%) which was significantly better than ERCP-BB alone (P=0.001) but not EUS-FNA alone (P=0.125). When both procedures were performed under the same conscious sedation, there was a significant difference (P=0.031) between the sensitivity of EUS-FNA (52.6%; 95% CI: 28.9-75.6%) and that of ERCP-BB (21.1%; 95% CI: 6.1-45.6%). When both procedures were performed together the mean±SD in-room time was 79±14 min (range: 45-105 min). Two of the patients (9.1%) had a complication. Conclusions In patients undergoing EUS-FNA and ERCP-BB under the same sedation, EUS-FNA was significantly more sensitive in diagnosing malignancy. Combining the results of both tests improved diagnostic accuracy. Combining therapeutic ERCP and EUS-FNA under the same conscious sedation is feasible, with a complication rate similar to that of ERCP alone.

description: Context Palliative procedures play an important role in the treatment of malignancies of the pancreatic head/distal biliary tree, as only 20-30% can be cured by surgical resection. Objective We sought to determine if surgical or non-surgical management was the most appropriate therapy for the treatment of obstructive jaundice in the palliative setting. Setting High volume center for pancreatic surgery. Patients Analysis of 342 palliatively-treated patients with adenocarcinoma of the pancreatic head or the distal biliary tree. Main outcome measures We studied the outcomes with regard to treatment, complications and survival times. Design The patients were divided into three groups. Group 1: endoscopic bile duct endoprosthesis (no. 138, 56%); Group 2: preoperative stenting followed by laparotomy (if patients were found to be unresectable, palliative hepaticojejunostomy was performed) (no. 68, 28%); Group 3: hepaticojejunostomy without preoperative stenting (no. 41, 16%). We also determined the frequency of re-hospitalization for recurrent jaundice. Results Two hundred and sixty-one (76%) patients showed obstructive jaundice. Mortality in Groups 1, 2, and 3 was 2.2%, 0%, and 2.4%, respectively and morbidity was 5.1%, 17.6%, and 14.6%, respectively. The mean interval between stent exchanges was 70.8 days. Median survival for patients treated only with an endoscopic stent (Group 1) was significantly shorter than that of patients who were first stented and subsequently treated with hepaticojejunostomy (Group 2) (5.1 vs. 9.4 months; P<0.001). Conclusions Hepaticojejunostomy can be performed with satisfactory operative results and acceptable morbidity. Considering that biliary stents can occlude, a hepaticojejunostomy may be superior to endoscopic stenting; hepaticojejunostomy should be especially favored in patients whose disease is first found to be unresectable intraoperatively.

description: Context The pancreas is an infrequent site of hydatid disease. Objective This study aims at giving better insight into the diagnostic and managerial approach to the disease. Patients Six patients with hydatid cysts of the pancreas. Design Retrospective review of the clinical records. Results The six patients (four men, two women) ranged in age from 18 to 68 years. Five of the cysts were primary while one had an associated cyst in the liver. Abdominal pain, vomiting, abdominal mass and dyspeptic symptoms were seen in cysts involving the body and tail. Two patients having cysts in the head of the pancreas presented with obstructive jaundice. An indirect hemagglutination test and an enzyme-linked immunoabsorbent assay were positive for the presence of specific hydatid antibodies in four patients. Abdominal ultrasonography, computed tomography and magnetic resonance cholangiopancreatography (MRCP) successfully imaged the cysts and also defined the relationship of the lesion with the pancreatic duct. All patients underwent surgical exploration. Three patients had intraoperative fine needle aspiration cytology of the cystic lesion for microscopic and electrolyte analysis. A preoperative diagnosis was possible in two patients and, in the other four, the diagnosis was made intraoperatively and confirmed on histopathological examination. Patients with cysts located in the tail underwent a distal pancreatectomy with a splenectomy while those with cysts in the body had a pericystectomy or central pancreatectomy. Cysts of the head were treated with evacuation, partial cystectomy and tube drainage. There were no postoperative complications, and no evidence of cyst recurrence was observed during the follow-up period. All the patients were followed up at three-month intervals with a mean follow-up time of 58.7 months (rang: 4-120 months); no patient had cyst recurrence or dissemination. Conclusion A hydatid cyst is an uncommon cause of cystic lesions in the pancreas and should be included in the differential diagnosis of cystic lesions of the pancreas, especially in endemic areas. Intraoperative fine needle aspirate for microscopic and electrolyte estimation seems to be an effective method for establishing a proper diagnosis. MRCP, which can depict the communication of the cystic lesion with the pancreatic duct, helps in defining the type of surgical treatment. Cysts in body and tail are best treated by resectional methods whereas, for those in the head region, a cystectomy with simple drainage is a simple, quick and effective solution.

description: The Durand Line (DL), which separates Pakistan from Afghanistan, is home to the Pashtuns on both sides of the border. Afghanistan has continuously rejected the Durand Line and upheld the right to self-determination for Pashtuns included within Pakistan by that line since 1947. Pakistan denies this claim, upholding the legality of the Durand Line, and considers the Afghan claim illegal under international law. Although it has been the official border between the two countries for more than a century, the Durand Line has been controversial for the local people. Pakistan has been pursuing an ambiguous policy towards Afghanistan and the international community for a long time. This article examines the implications of the Durand Line and highlights the strategies of both Pakistan and Afghanistan. The present study employs doctrinal research and is limited to the positions of Afghanistan and Pakistan over the Durand Line.

description: Context Recent studies have shown high amplitude K-ras gene mutation and allelic imbalances are predictive of malignancy in pancreatic cysts. Objective Our purpose is to determine the added benefit of molecular testing in diagnosing small pancreatic cysts. Design Retrospective, single-institution study. Patients Patients with pancreatic cysts (less than, or equal to, 3 cm) who presented for EUS evaluation. Intervention EUS-guided pancreatic cyst aspiration cytology, carcinoembryonic antigen (CEA) level determination, and detailed DNA analysis including K-ras gene mutation and allelic imbalance. Main outcome measurements Ability of cyst fluid DNA analysis to render a diagnosis compared with cytology and CEA level determination. Results Diagnostic agreement was seen in 55.6% (35/63) of cases. In 10 cases (15.9%), there was disagreement between cytology and molecular. Molecular testing provided a diagnosis in 20 cases (31.7%) when either cytology was unsatisfactory, or CEA not elevated (less than 192 ng/mL). Elevated CEA levels were seen in 16 cases (25.4%), each diagnosed as a mucinous lesion with molecular analysis. Conclusions Molecular analysis of pancreatic cyst fluid adds diagnostic value in scant specimens when cytology may be unsatisfactory and CEA unreliable.
