SPATIAL POLICY DILEMMA: ENVIRONMENTAL SUSTAINABILITY AND ECONOMIC GROWTH
Authors: Budiman Haris , Suparman Eman , Mashdurohatun Anis
Published: August 2019

The regulation of spatial planning aims to meet the demands of the built-area and preserve the environment for sustainable urban development. Yet, the implementation of spatial planning for welfare and environmental sustainability faces various problems such as conflicts between sectors and regions. Similarly, the efforts to improve welfare through economic growth lead to land conversion that has an impact on environmental demage and land conflicts. The purpose of this study is to analyzethe factors inhibiting local governments in implementing the spatial planning. This research belongs to qualitative research with Socio Legal approach. The informants and respondents were chosen by applying purposive sampling technique, while the data validation used triangulation. The results showed that local governments have difficulties in implementing environmental-based spatial planning as well as increasing economic growth, especially for regions with small local revenues. Limited resources, inconsistenct policy, and weak regulation arrangements have become inhibiting factors in meeting the demands of environmental-based spatial planning and increasing economic growth. Therefore, commitment from local government is needed to solve the problem by increasing the capacity of government apparatus, enforcing the rules, and reconstructing the fair and prosperous spatial policy.
A review and updated classification of pollen gathering behavior in bees (Hymenoptera, Apoidea)
Authors: Portman Zachary M. , Orr Michael C. , Griswold Terry
Published: August 2019

Pollen is the primary protein and nutrient source for bees and they employ many different behaviors to gather it. Numerous terms have been coined to describe pollen gathering behaviors, creating confusion as many are not clearly-defined or overlap with existing terms. There is a need for a clear yet flexible classification that enables accurate, succinct descriptions of pollen gathering behaviors to enable meaningful discussion and comparison. Here, we classify the different pollen gathering behaviors into two main classes: active and incidental pollen collection. Active pollen collection is subdivided into six behaviors: scraping with the extremities, buzzing, rubbing with the body and/or scopae, rubbing with the face, tapping, and rasping. In addition to the active and incidental pollen gathering behaviors, many bees have an intermediate step in which they temporarily accumulate pollen on a discrete patch of specialized hairs. Each behavior is described and illustrated with video examples. Many of these behaviors can be further broken down based on the variations found in different bee species. Different species or individual bees mix and match these pollen collecting behaviors depending on their behavioral plasticity and host plant morphology. Taken together, the different behaviors are combined to create complex behavioral repertoires built on a foundation of simple and basic steps. This classification sets the groundwork for further research on various topics, including behavioral plasticity in different species, comparisons between generalists and specialists, and the relative effectiveness of different pollen gathering behaviors.

Published: August 2019

Fishes are a paraphyletic group composed by craniates except for the four-limbed clade Tetrapoda. This group was the only vertebrate representative until the Devonian but now comprises almost half of the vertebrate species, dominating nearly all aquatic environments. The fossil record is the key to understand the ancient paleobiodiversity and the patterns that lead the modern fish fauna, and paleontological collections play a fundamental role in providing accommodation, maintenance, and access to the specimens and their respective metadata. Here we present a systematic checklist of fossil fishes housed in the type collection of the Colección Nacional de Paleontología which is located at the Instituto de Geología of Universidad Nacional Autónoma de México. Currently housed in the type collection are 14 chondrichthyan specimens, belonging to two superorders, five orders, seven families, 10 genera, and five nominal species, and 361 osteichthyan specimens, belonging to eight orders, nine families, nine genera, and 26 nominal species. These fossils come from 32 localities and 15 geological units, which range temporally from the Jurassic to the Pleistocene. The paleoichthyofauna housed in the type collection of the Colección Nacional de Paleontología is remarkable for its singularity and reveals new insights about the origin and diversification of many groups of fishes. The recovery and curation of this fossil material indicates that knowledge of Mexican fossil fish diversity and its role in understanding lower vertebrate evolution are just emerging and reaffirms the importance of the biological and paleontological collections to the future biodiversity research.

Published: August 2019

Consecuencia de una profunda reforma decimonónica inacabada, la capilla de los Tocino había perdido su uso y relación espacial original con el ábside de la iglesia de San Juan de los Caballeros de Jerez de la Frontera al que se adosa. La degradación que sufrió la capilla desde ese momento fue enorme. La interpretación de sus lesiones estaba muy condicionada por el devenir del mismo, siendo necesaria una serie de trabajos previos y paralelos a la intervención para reconocer esta complejidad y determinar los valores patrimoniales sobre los que fundamentar el proyecto. Se planteó así una estrategia de acciones de investigación cuyo alcance debía ser proporcional a los recursos económicos disponibles y los enfoques analíticos que pretendíamos integrar. Entre ellas se programó una intervención arqueológica que incorporaba el análisis del subsuelo y estudio paramental. Se expondrá el resultado de un trabajo integrado que se prolongó hasta finalizar su consolidación material, espacial y funcional.
Resurrection of the sea pen genus Ptilella Gray, 1870 and description of Ptilella grayi n. sp. from the NE Atlantic (Octocorallia: Pennatulacea)
Authors: García-Cárdenas Francisco J. , Drewery Jim , López-González Pablo J.
Published: August 2019

The order Pennatulacea covers a group of specialized and morphologically distinct octocorals found in all oceans from intertidal areas to more than 6000 m in depth. Sea pens constitute an important structural component in marine soft-bottom communities by increasing the complexity of these environments. Despite being both morphologically distinctive and ecologically important, the taxonomy and systematics of sea pens is still poorly understood. Recent molecular studies have shown the existence of convergent morphological features, making the current familial distribution of genera unstable. The genus Pennatula Linnaeus, 1758 was one of the first described octocoral genera. It is the type genus of its family, Pennatulidae. Colonies of this genus have a characteristic morphology. Recent sampling efforts in the northeastern Atlantic have provided a number of colonies initially attributable to the genus Pennatula. Both morphological and molecular (mtMutS, Cox1 and 28S genes) study of this material supports the polyphyletic nature of this genus and the need to resurrect the genus Ptilella Gray, 1870 to accommodate these and other species. A new species, Ptilella grayi n. sp., is described and illustrated. The species Pennatula bayeri is proposed to be a junior synonym of Pennatula bellissima (here also considered in the genus Ptilella).
Stony corals (Anthozoa: Scleractinia) of Burdwood Bank and neighbouring areas, SW Atlantic Ocean
Authors: Schejter Laura , Bremec Claudia S.
Published: August 2019

The presence of ten species of stony corals was recorded at a total of 19 out of 48 sampling stations at Burdwood Bank and neighbouring areas. Scleractinians were recorded only at three stations inside the marine protected area (MPA) Namuncurá I, while the majority of them were recorded deeper than 200 m. Burdwood Bank slope (MPA Namuncurá II + NW slope) was the richest sub-area, with ten species recorded in the present study and another two species mentioned from the literature. For the majority of the species the results here presented represent the only available data in the study area after 50 years (or more), comprising updates of latitudinal and bathymetric ranges. Stony corals were recorded as basibionts of a variety of organisms. Mainly dead skeletons were found providing a suitable settlement substrate for sessile species such as primnoid corals. The presence of a high richness of stony corals on the southern slope of Burdwood Bank, as components of the marine animal forests recorded, also supported the conservation efforts made to create the new MPA named “Namuncurá/Burdwood Bank II” in this region.

Published: August 2019

Drilling is a chip machining process widely used in manufacturing .The term drilling includes all methods for making cylindrical holes in a work piece with chip cutting tools. There are many applications where drilling is used, such as drilling holes in PCBs. Robotic systems are used today to perform the drilling process. A problem that affects the use of these systems is the drilling sequence, as there are usually a number of points to visit. The determination of the drilling sequence is similar to the problem of synchronization of movement and travel time. The main objective is to optimize the time and trajectory of the three axes robot equipped with an automatic drill that seeks the best performance. In this paper, we have built a genetic optimization and problem solving algorithms to shorten the machining time to drill a given group of holes and reduce machining costs in order to improve the efficiency of the machining process as well robotic machining with three axes without degradation of the precision of the movement. The results of the experiments show that the proposed approach is feasible and practical. It is particularly useful in planning and scheduling systems for real-time manufacturing processes.

Published: August 2019

Development of small hydropower plants depends on its economic and financial feasibility, which must be evaluated by cost estimates before construction. Cost of electromechanical (EM) equipment represents the major portion of the total plant budget. The paper presents new cost estimation approach for EM equipment of hydropower plants. Compared to the literature approaches, the proposed cost correlation is elaborated basing on dataset of hydropower plants located in different continents. Furthermore, the transport cost has been considered of continental factors. Mono-and multi-objective genetic algorithm (GA) optimization have been both applied and compared to determine the best cost correlation. The accuracy of this best cost correlation is validated by using statistical analysis tools to compare it with the equation deduced from the best model reviewed in the literature. The results have shown that the bivariate correlation, viz., the Pearson Product Moment Correlation Coefficient (PPMCC), is slightly improved from 98 % to 99 %. The Mean Square Relative Error (MSRE) is substantially improved from 4.47 % to 1.82 %, and the Utmost Square Relative Error (USRE) from 45.2 % to 11.4 %. Indeed, the proposed cost correlation gives a more accurate estimate of EM equipment cost of hydropower plants in different continents.

Persea Americana is well known for its short shelf life while the seed is widely considered a waste material by domestic consumers and industry processors. This paper presents the results of the study carried out to evaluate the possibility of using three parts of the Persea Americana namely: its seed, a combination of the Persea Americana seed and its pulp and the Persea Americana pulp as filtration loss control additives in a non-aqueous drilling fluid while using Sodium Asphalt Sulfonate as a control. The evaluation was conducted under high pressure, high temperature (HPHT) static filtration test conditions (at 250°F and 500 psi) based on American Petroleum Institute Standard. From the study, the result showed that all three samples from the Persea Americana fruit showed good potential to control filtration loss when used to formulate a synthetic oil based mud. The filtration control capacity increased as their concentration in the mud was increased. However, in comparison, the pulp was 2.5 times and 1.5 times more efficient in controlling filtration loss when compared to the seed only and the seed and pulp combination respectively. Also, in terms of filtrate volume and filtered cake thickness, an equal concentration of Sodium Asphalt Sulfonate and the proposed additive gave good results; but the existing filtration loss control additive is slightly better than the proposed one. The low fluid loss volumes recorded with Persea Americana as fluid loss additives at HPHT conditions is an indication of its stability at elevated temperature conditions. The cake thickness was thin, impermeable and 1mm in size for all the samples of the Persea Americana. This meets the API requirement of mud cake thickness of less than 2mm.

Modified coconut oil (MCO) has been reported as a promising material for eradication of various fungi which are the primary causes of tinea capitis. The antifungal shampoo is reported as an effective adjuvant therapy for fungi infection. In order to develop MCO as an active ingredient in antifungal shampoo, formulation factors affecting the physical and antifungal properties of shampoo including type and amount of surfactants were investigated. The results indicated that formula containing triethanolamine lauryl sulfate (TLE), ranging from 40-70% w/w, showed the most transparency and stable among the primary surfactants used, suggesting the good compatibility with MCO. An addition of polyoxyethylene 20 sorbitan monolaurate (PSL), an auxiliary surfactant, in the range from 5-40%w/w could enhance the clearness of shampoo while the suitable amount of PSL is also depended on TLE concentration. Various surfactant mixtures of TLE ranging from 40-60%w/w and 20-40% w/w of PSL were selected to formulate MCO shampoo. All formulations of shampoo showed high transparency, effective cleaning action, good stability and Newtonian flow behavior. Moreover, all formulations could inhibit T. rubrum and M. canis both before and after temperature cycling test. Therefore, this study revealed good feasibility of MCO shampoos for tinea capitis treatment.

Andrographolide (AG) is a diterpenoid lactone found in Andrographis paniculata leaves and stems. It has excellent activity against various cancer cells, for example, skin cancer cells. However, application of AG for skin cancer treatment in clinical trials is limited due to its poor water solubility. To overcome this problem, oil in water AG-loaded nanoemulsion (AG-NE) would be prepared. The objectives of this study were to investigate physicochemical properties of AG-NE and to determine its activity against non-melanoma skin cancer cells. Nanoemulsion (NE) without AG (NE base) and NE containing AG (0.1%w/w) were prepared by high-pressure homogenization technique. They contained a mixture of Tween 80 and Span 80 (5:1) (10% w/w) as an emulsifier. Their droplet size, zeta potential and physical stability were evaluated. Cytotoxicity of AG and AG-NE to non-melanoma skin cancer cells (A-431 cells) and normal skin fibroblast cells (HFF-1 cells) were investigated. The results showed that NE base and AG-NE had droplet size in a nanometer range. They had low viscosity with the flow behavior consistent with Newtonian liquids. Although their zeta potential values were slightly low, they showed good physical stability against centrifugal force. AG and AG-NE were not toxic to HFF-1 cells, but they could induce apoptosis of A-431 cells with IC50 of 25.83 μg/ml and 58.32 mg/ml, respectively. Therefore, AG-NE has become possible to use for investigation of its efficacy and safety in animal models and clinical trials.

Nanofibers have been widely used for tissue engineering. Using charged polymers for the preparation of nanofibers can be useful for the loading of substances or macromolecules. Dual charge nanofiber mats are expected to be able to immobilize both positively charged and negatively charged substances in one versatile nanofiber mat. The purpose of this study was to prepare and characterize dual-charge nanofibers generated from poly (vinyl alcohol) (PVA)/poly-(acrylic acid-co-maleic acid) (PAMA) and chitosan (CS)/PVA. The polymer solutions of PAMA/PVA (1:1.63 w/w) and CS/PVA (1:2.33 w/w) were electrospun to form the nanofibers using dual-jet electrospinning process. The obtained dual-charge nanofibers were thermally crosslinked by leaving the nanofibers in the oven at 110-130 °C for 0.5, 1, 3, 5 h. The appearance of the nanofiber mat was characterized by a scanning electron microscope (SEM), and the diameter of nanofibers were determined by an image analysis software (J-micro vision®). The percentage water insolubilization and FT-IR spectra were also determined. The dual-size nanofiber mats with smooth and bead-free fibers were obtained. The diameter of the PAMA/PVA and CS/PVA fibers was 574.54 ± 142.98 nm and 225.69 ± 41.92 nm, respectively. The desirable temperature and time for the crosslink of the dual-charge nanofiber mats was 130 °C for 1 h which could provide a high insolubilization with water capacity of 93.22 ± 2.23%.

Niosomes are a lipid nanoparticle which have been widely used as non-viral carrier for therapeutic DNA or siRNA. They are formulated from non-ionic surfactant and other helper lipids. The aim of this study were to formulate niosome containing spermine-based cationic lipid with different linkers and to evaluate the efficiency of siRNA delivery in cervical cancer cell (HeLa cell). The niosomes were formulated from cholesterol (Chol), Span 20 and different cationic lipid (Ay, By, Cy and Dy) at various molar ratios. The properties of niosomes and ability of niosome to complex with siRNA were characterized. The cellular uptake, gene silencing efficiency and cytotoxicity were also determined. From the results, niosomes formulated at Chol:Span20:lipid molar ratio of 2.5:2.5:2 showed positive zeta potential and they were in nanosize (<200 nm). The binding ability of cationic niosomes to siRNA depended on types of cationic lipid. Among niosome/siRNA complexes, the niosome By/siRNA complex provided the highest gene silencing efficiency at weight ratio of 20. The highest cellular uptake also obtained by using niosome By as a carrier. The cytotoxicity revealed that cationic niosomes had low toxicity (cell viability > 80%). In conclusion, the cationic niosomes prepared from Chol, Span 20 and spermine-based cationic lipids are able to complex with siRNA and suitable for siRNA delivery with low toxicity.

Pueraria mirifica (PM) extract is locally used to promote hair growth. However, the effective transdermal delivery system should be prepared to deliver the extract through the skin barrier. The objective of this study was to develop solid lipid nanoparticles (SLN) containing PM ethanolic extract for hair growth promotion. The cell viability and proliferation of human follicle dermal papilla cells (HFDPCs) treated with PM extract were evaluated by MTT assay. SLN formulations were developed as a transdermal delivery system of the PM extract, compared with liposomes. The physicochemical properties of these nanoparticles were determined. The in vitro skin permeation study was also evaluated by Franz type diffusion cells. For the result, PM extract was a good safety herbal extract, which no cytotoxicity at the concentrations from 1 to 1,000 μg/ml. The cell proliferation of PM extract treated HFDPCs significantly increased in a dose-dependent manner, indicating the possibility to promote hair growth at the concentrations from 10 to 100 μg/ml. For formulation development, 5% (w/v) PM extract-loaded SLN exhibited small particle size (93.83 ± 0.32 nm) with narrow size distribution and negatively charged. This formulation had the highest percent entrapment efficiency (42.64 ± 0.47%), followed by SLN containing 1% (w/v) PM extract (8.84 ± 0.24%) and undetectable in liposomes. For the skin permeation result, SLN containing 5% (w/v) of PM extract could penetrate through the skin more than solution form. Therefore, the small particle size and high PM extract entrapped in SLN exhibited higher PM extract penetrated through the skin barrier and hair follicles than PM ethanolic extract solution. PM extract-loaded SLN might be an effective formulation for hair growth disorders treatment.
