Konsistensi Dan Korelasi Antara UUD 1945 Dan Uupa 1960

UUPA 1960, as the first constitution created to unite the national agrarian law, was designed to manage agrarian matters. The constitution was made in accordance to Pancasila as its philosophical foundation and the 1945 Constitution as its constitutional base. In the current political agrarian dynamics, as a consequence of changes in facing globalisation era, UUPA 1960 is expected to be able to anticipate these changes and adjust to the ever developing aspirations

Topical Antibacterials and Global Challenges on Resistance Development

Purpose: The skin acts as the first line of defence against the invasion of microorganisms. Damage to the skin such as abrasion, bruises and trauma will expose underlying tissue to bacterial infection. Minor skin infections can be easily treated with topical antibacterial medication that is available over the counter or by prescription. On the other hand, serious bacterial skin infections can be life-threatening and may require complex  interventions such as medical or surgical methods to cure the disease. The treatments given have to be assessed according to the presentation, aetiology, chronicity of the wound (depth and size) and/or skin lesions. For skin bacterial infection, topical route of administration is preferred over systemic administration due to the delivery of a higher concentration of medication for the former into the desired area. It is also less likely to cause systemic side effects, toxicity, and bacterial resistance. There is ongoing controversy and debate regarding the likelihood of developing bacterial resistance with the usage of topical antibiotics as an antibacterial. This could be due to inappropriate  antibiotic use resulting from self-medication, over the counter availability, prescribing on demand and a lack of regulatory control.Keywords: Topical antibacterial, Bacterial resistance, Self-medication, Inappropriate antibiotic use, Dispensin

Technical-economic comparison of chemical precipitation and ion exchange processes for the removal of phosphorus from wastewater

Chemical precipitation with the addition of ferric chloride is commonly used to remove phosphorus from wastewater. However, since its application also involves several disadvantages, alternative solutions are required. The present paper shows the results of a full-scale experimental work aimed at evaluating the efficiency of the ion exchange process using a polymeric anion exchange resin impregnated with aluminum ions in the removal of phosphorus from wastewater. The study compared the results obtained through this process with chemical precipitation, considering both technical and economic issues. At the same dosage of 6 L/hour and influent concentration (about 6 mg/L), total removal efficiency of 95% and 78% (including also that occurring in the mechanical and biological processes) was achieved by means of the anion exchange process and chemical precipitation, respectively. However, in the latter case, this value was insufficient to ensure consistent compliance with the limit of 2 mg/L Ptot set on the effluent; to achieve this goal, the ferric chloride dosage had to be raised to 12 L/hour, thus increasing the related costs. Furthermore, the anion exchange process generated a lower sludge production. Therefore, the ion exchange process represents a valid alternative to chemical precipitation for P removal from wastewater

Perovskite CsPbBr3 Solar Cells With Novel Hole-Transporting Layer of Metal Complexes

For the first time, the novel application of Schiff-base copper complexes in all-inorganic perovskite CsBrBr3 solar cells has been explored and turns out they could be utilized as effective hole-transporting materials. Schiff-base copper complexes with halogen ligands (R=Cl and Br) are synthesized with an ease approach at a low cost, both of which exhibit decent power conversion efficiency of 4.55% and 5.71%, respectively, when being constructed into solar devices as hole transport layers. Thanks to high thermal/chemical stability of those Schiff-base metal complexes, the strengthened stability was achieved which is comparable to that of carbon-based CsBrBr3 solar cells. Although the power conversion efficiency is not as competitive as expected, the great potential exists for further optimizing the functionality of perovskite solar devices by finely tuning the photovoltaic properties of those Schiff-base metal complexes through coordinating ligands or replacing with other transition metals

Imaging stress and magnetism at high pressures using a nanoscale quantum sensor.

Pressure alters the physical, chemical, and electronic properties of matter. The diamond anvil cell enables tabletop experiments to investigate a diverse landscape of high-pressure phenomena. Here, we introduce and use a nanoscale sensing platform that integrates nitrogen-vacancy (NV) color centers directly into the culet of diamond anvils. We demonstrate the versatility of this platform by performing diffraction-limited imaging of both stress fields and magnetism as a function of pressure and temperature. We quantify all normal and shear stress components and demonstrate vector magnetic field imaging, enabling measurement of the pressure-driven [Formula: see text] phase transition in iron and the complex pressure-temperature phase diagram of gadolinium. A complementary NV-sensing modality using noise spectroscopy enables the characterization of phase transitions even in the absence of static magnetic signatures

Laboratory Evaluation of Flurox, a Chitin Synthesis Inhibitor, on the Termite, Microcerotermes diversus

Microcerotermes diversus (Silvestri) (Isoptera: Termitidae) is the most economically destructive termite in structures in southwest Iran. One sustainable control strategy that usually helps to reduce subterranean termite damage in buildings, is the use of insect growth regualtors in a suitable bait matrix that are safe to the user and the environment. In the laboratory assays described here, the delayed toxicity of Flurox, a chitin synthesis inhibitor, to M. diversus was evaluated under force-feeding and choice trials. Flurox induced worker and nymph mortality and incomplete ecdysis in nymphs of M. diversus under no-choice and two-choice feeding tests. These adverse effects may cause disruption of the caste balance in M. diversus, leading to the collapse of the colony. These assays determined concentrations of Flurox that can be used in bait formulations

Ab-initio study of electronic properties of a two-dimensional array of carbon nanotubes

This is the final version. Available from IOP Publishing via the DOI in this record. The equilibrium geometry and electronic band structure of a planar array of carbon nanotubes are studied with the use of the Quantum Espresso code - a plane-wave realisation of the density functional theory (DFT). The many-electron correlations and van der Waals corrections are taken into account. The optimal distance between nanotubes in the array corresponding to the minimum of the total energy of the system is found. A strongly anisotropic hyperbolic dispersion is demonstrated for low-energy charge carriers in an array of quasi-metallic (15,0) carbon nanotubes with the optimal inter-tube separation governed by van der Waals forces.Icelandic Research FundEuropean Union Horizon 2020Ministry of Education and Science of Russian FederationGovernment of Russian Federatio
