Prolog and inductive reasoning: a logic programming language

This following research presents the design and development of a diagnostic medical system. The proposed system provides an interactive and adaptive environment through which symptoms are linked with illness. Each new patient is asked a yes/no question concerning his or her symptoms, and responses are recorded. The diagnosis works by matching symptoms of known illness with recorded responses in decreasing order of complexity. Inductive reasoning (in the form of generalization) is used to update illness symptoms. The system is implemented in Prolog SWI- Version 6.0.0.Includes bibliographical references (pages 66-69)California State University, Northridge. Department of Computer Science

Tailoring porosity and rotational dynamics in a series of octacarboxylate metal-organic frameworks

Modulation and precise control of porosity of metal-organic frameworks (MOFs) are of critical importance to their materials function. Here we report the first modulation of porosity for a series of isoreticular octacarboxylate MOFs, denoted MFM-180 to MFM-185, via a strategy of selective elongation of metal-organic cages. Owing to the high ligand connectivity, these MOFs show absence of network interpenetration, robust structures and permanent porosity. Interestingly, activated MFM-185a shows a record high BET surface area of 4734 m2 g-1 for an octacarboxylate MOF. These MOFs show remarkable CH4 and CO2 adsorption properties, notably with simultaneously high gravimetric and volumetric deliverable CH4 capacities of 0.24 g g-1 and 163 v/v (298 K, 5-65 bar) recorded for MFM-185a due to selective elongation of tubular cages. Dynamics of molecular rotors in deuterated MFM-180a-d16 and MFM-181a-d16 were investigated by variable-temperature 2H solid state NMR spectroscopy to reveal the reorientation mechanisms within these materials. Analysis of the flipping modes of the mobile phenyl groups on the linkers, their rotational rates and transition temperatures, paves the way to controlling and understanding the role of molecular rotors through organic linker design within porous MOF materials

A robust binary supramolecular organic framework (SOF) with high CO2 adsorption and selectivity

A robust binary hydrogen-bonded supramolecular organic framework (SOF-7) has been synthesized by solvothermal reaction of 1,4-bis-(4-(3,5-dicyano-2,6 dipyridyl)dihydropyridyl)benzene (1) and 5,5’-bis-(azanediyl)-oxalyl-diisophthalic acid (2). Single crystal X-ray diffraction analysis shows that SOF-7 comprises 2 and 1,4-bis-(4-(3,5-dicyano-2,6-dipyridyl)pyridyl)benzene (3), the latter formed in situ from the oxidative dehydrogenation of 1. SOF-7 shows a three-dimensional four-fold interpenetrat-ed structure with complementary O−H···N hydrogen bonds to form channels that are decorated with cyano- and amide-groups. SOF-7 exhibits excellent thermal stability and sol-vent and moisture durability, as well as permanent porosity. The activated desolvated material SOF-7a shows high CO2 sorption capacity and selectivity compared with other po-rous organic materials assembled solely through hydrogen bonding

Analysis of high and selective uptake of CO2 in an oxamide-containing {Cu2(OOCR)4}-based metal-organic framework

The porous framework [Cu2(H2O)2L].4H2O.2DMA ((H¬4¬L = oxalylbis(azanediyl)diisophthalic acid; DMA = N,N-dimethylacetamide), denoted NOTT-125, is formed by connection of {Cu2(RCOO)4} paddlewheels with the isophthalate linkers in L4-. A single crystal structure determination reveals that NOTT-125 crystallises in monoclinic cell with a = 27.9161(6) Å, b = 18.6627(4) Å and c = 32.3643(8) Å, space group P2 (1)/c. The structure of this material shows fof topology, which can be viewed as the packing of two types of cages (Cage A and Cage B) in 3-dimensional space. Cage A is constructed by twelve {Cu2(OOCR)4} paddlewheels and six linkers to form an ellipsoid-shaped cavity approximately 24.0 Å along its long axis and 9.6 Å across the central diameter. Cage B consists of six {Cu2(OOCR)4} units and twelve linkers with a spherical diameter of 12.7 Å taking into account the van der Waals radii of the atoms. NOTT-125 incorporates oxamide functionality within the pore walls, and this, combined with high porosity in the desolvated NOTT-125a, is responsible for excellent CO2 uptake (40.1 wt% at 273 K and 1 bar) and selectivity for CO2 over CH4 or N2. Grand canonical Monte Carlo (GCMC) simulations show excellent agreement with the experimental gas isotherm data, and a computational study into the specific interactions and binding energies of both CO2 and CH4 with the linkers in NOTT-125 reveals a set of strong interactions between CO2 and the oxamide motif, which are not possible with a single amide

Epidemiology Of Dengue Fever, Role Of Pharmacist, Nursing, Paramedics, Physiotherapist And Respiratory Therapist In Applying Prevention Measures

Dengue virus (DENV) is a contagious illness that is spread by Aedes mosquitoes. The extensive proliferation of these mosquitoes has contributed to a significant public health concern, as this virus transmitted by mosquitoes is prevalent in numerous locations, particularly in tropical and subtropical climates. Contracting dengue fever can result in severe symptoms that have the potential to be life-threatening. Dengue infections can manifest as asymptomatic, mild-to-moderate, or severe, contingent upon the characteristics of the individual. Dengvaxia is authorized for immunization in vulnerable children who have already contracted dengue. Pharmacists have the ability to support and promote immunization efforts, offer guidance on safe travel practices, and help in the care of patients with dengue. Understanding the clinical appearance and proper care of dengue is crucial in reducing the severity of symptoms in patients. Healthcare professionals, such as pharmacists, nurses, paramedics, physiotherapists, and respiratory therapists, can play a role in the effort to enhance patient outcomes for those infected with D

Enhanced CO 2

A new NbO-type metal-organic framework ZJNU-40 incorporating highly polarized benzothiadiazole moieties exhibits a high CO2 uptake of 108 cm(3) g(-1) at 296 K and 1 atm, as well as good adsorption selectivities of CO2 over CH4 and N-2 at room temperature, which is superior to that of the analogous MOF NOTT-101

The purpose of this study is to investigate how unaccompanied children have contributed to or affected Swedish society, and how society's reception has affected these children in 2015. This study investigates the situation of unaccompanied children in Sweden in 2015, a year marked by an increased flow of asylum seekers and concerns that came with receiving and integrating these children. The project aims to shed light on the complicated variations in reception of unaccompanied children as well as their impact and contribution on Swedish society. The study conducts interviews with unaccompanied children and representatives from Swedish society using qualitative semi-structured interviews.   The result showed that unaccompanied children in 2015 have influenced and contributed to Swedish society. By working, paying taxes and also participating in society's various social systems. It turned out that society has influenced the children both positively and negatively. Freedom affected them positively and authorities such as the Swedish Migration Agency have affected them negatively. Unaccompanied children have shown gratitude to Swedish society despite several shortcomings that existed since their arrival in 2015. The children had been given great opportunities for development such as education, freedom and a safe life

Optimized sandwich wall in prefabricated concrete

As part of the work in this project, a literature review is conducted to determine the optimal thickness of the outer concrete layer in prefabricated concrete sandwich elements. These elements are used as exterior walls in buildings and consist of a load-bearing inner concrete layer, an intermediate insulation layer, and an outer concrete layer that forms the building's facade. The focus is on optimizing the sandwich wall in precast concrete by reducing the thickness of the outer skin compared to the current standard thickness of 80 mm. This could potentially reduce the weight of the elements by approximately 1.5-2 tons by reducing the thickness from 80 mm to 30 mm. This weight reduction can have a significant impact, for instance, on the crane capacity in large construction projects, allowing a crane to handle all the elements on a construction site without the need for relocation. Additionally, this optimization of the sandwich wall will result in cost savings by using less material in the elements, as well as impacting other aspects of the construction process, such as energy consumption and transportation costs. In this project, test specimens of size 400mm x 400mm have been used, and to draw comprehensive conclusions, full-scale experiments are required to account for factors such as temperature variations and shrinkage in the outer skin. In this work, compressive strength tests have also been conducted to determine the strength of the concrete used in the outer skin of the tested sandwich walls. The concrete used in the tests was a fiber-reinforced concrete from Finja, and the reinforcing mesh was a hot-dip galvanized plaster mesh. Initially, samples were cast to test the laboratory equipment and evaluate the testing methods. Subsequently, the remaining samples were cast and tested according to a predetermined schedule to ensure relevant testing conditions. Samples on the wall elements were made with both diagonal and straight anchoring and were tested under tensile load parallel to the outer layer as well as tensile load perpendicular to the outer layer. In total, 20 samples were conducted in the study, testing various combinations of anchoring systems, loads, reinforcement, and recesses. Samples 1-10 were tested with diagonal anchoring and parallel load, while samples 11-20 were tested with perpendicular anchoring and perpendicular in combination with parallel load. The samples exhibited a variation in failure types, such as grain failure in the outer layer, anchor pull-out, adhesion, and outer layer failure. The highest load values were observed in sample 2 (8.7 kN) and 6 (7.6 kN) for samples 1 to 10, and sample 12 (10.6 kN) and 15 (9 kN) for samples 11 to 20. In summary, it can be stated that the trials have yielded initially positive results regarding the practical use of a thinner outer panel for prefabricated concrete sandwich elements
