Early Generation Selection within a Diploid Hybrid Solanum tuberosum Groups Phureja and Stenotomum Population for the Intense Yellow-flesh Creamer Potato Market
Authors: Haynes Kathleen G. , Zotarelli Lincoln , Christensen Christian T. , Walker Stephanie
Published: December 2019

Consumer demand for specialty market potatoes has been growing. Cultivated South American diploid potatoes possess great variation for skin and flesh colors, shape, and taste. A long-day adapted population of Solanum tuberosum groups Phureja and Stenotomum (phu-stn) was evaluated for characteristics associated with the type known as papa criolla or papa amarilla in South America. Tubers have intense yellow flesh and may be fried or roasted and eaten whole. A U.S. northern location (Maine), representative of a seed growing region, and two southern locations (Florida and New Mexico), representative of potato growing regions near large Hispanic populations, evaluated yellow-fleshed clones selected within a phu-stn population. Agreement between selectors at two locations was greater than 50%. Tuber skin color and shape were highly correlated between locations; flesh color and tuber dormancy moderately so; eye depth had low correlation between locations; and appearance and skin texture had low or no correlation between locations. Tuber dormancy was generally short, but a few longer dormant clones were identified. There were significant differences among clones for yields, with the highest yields occurring in Maine. More intense evaluations are planned for a subset of these clones before possible release as new varieties. Future breeding efforts will be undertaken to lengthen tuber dormancy in this population.

Published: December 2019

Excessive nitrogen (N) use in agriculture has been associated with increased severity of the damage caused by Phytophthora species. In this study, we investigated the impact in vitro and in vivo of N about Phytophthora cinnamomi. The preliminary in vitro assay showed the effect of different N sources on the mycelial growth of P. cinnamomi. This assay indicated that ammonium nitrate (NH4NO3) and ammonium sulfate [(NH4)2SO4] allowed for greater control of P. cinnamomi mycelia in comparison with calcium nitrate [Ca(NO3)2] and potassium nitrate (KNO3) when used with 1000 ppm N. The in vivo assay showed the severity of P. cinnamomi in 5-month-old Juglans regia saplings grown under greenhouse conditions. We selected NH4NH3 as the source for N for the greenhouse assay, considering the inhibitory effect on the ingrowth of P. cinnamomi and the intensive use of this fertilizer in agriculture. Walnut saplings were fertilized with 0, 35, 70, 140, 210, and 1050 ppm N and were inoculated with zoospores of P. cinnamomi 45 d after the application of nitrogen treatment (DAA). They were harvested at 90 DAA. We found that a 70-ppm N fertilization reduced the development of P. cinnamomi, resulting in lower root and canopy damage indices (DIs) than the unfertilized inoculated treatments and fertilized treatments greater than 140 ppm. The results of the in vitro and in vivo assay agree that increased N concentrations were associated with reduced mycelium growth of P. cinnamomi, providing further evidence that N fertilization can mitigate this disease. Greater root and canopy damage was observed in saplings fertilized with 1050 ppm N, regardless of whether they were inoculated with P. cinnamomi, as a result of N phytotoxicity (verified through foliar analysis). In contrast, inoculated and unfertilized saplings (N0) also showed high root and canopy DIs associated either with the inoculation with P. cinnamomi or the no fertilization treatment. We postulate that 70 ppm N is the best fertilization rate for J. regia saplings because the positive effects of N on growth are maximized and the damage caused by P. cinnamomi is mitigated.

Published: December 2019

Under high‐density planting, mixed cropping planting pattern can potentially optimize maize (Zea mays L.) canopy architecture and ultimately improve grain yield. The objectives of this study were to evaluate the effects of three plant patterns combined with three plant population densities (67,500, 82,500, and 97,500 plants·ha−1) on canopy architecture and grain yield. Zhengdan 958 (ZD958) and Denghai 605 (DH605) were used as experimental materials. Three different planting patterns were: mixture (M), random sowing after mixing seeds of the two hybrids in the same proportion; 1:1, one row of ZD958 and one row of DH605; and two monoculture systems, SZD958 and SDH605, as controls. A 3‐yr study demonstrated that the mixed cropping treatments (M and 1:1) at low density (LD) showed no significant difference on light transmission, leaf area index (LAI), canopy apparent photosynthesis (CAP), and canopy respiration (CR), compared with the two monocultures. However, at a medium and high density (MD and HD), mixed cropping was characterized with higher light transmission to the ear and lower layers of the canopy during grain filling than that of monoculture treatments, while no significant differences between M and 1:1 treatments. Moreover, mixed cropping treatments maintained a higher LAI, CAP, lower CR, and increased the whole and post‐silking dry matter accumulation. Grain yields were higher under mixed cropping at MD and high density (HD), while no significant differences between M and 1:1 treatments. Relative to SZD958 and SDH605, the grain yields in the M treatment were 10% and 8% higher at MD, and 7% and 5% higher at HD, respectively. Mixed cropping optimized the canopy structure, maintained higher LAI and CAP during the grain filling period, reduced respiration, and increased aboveground dry matter at maturity. These improvements also result in higher grain yield.

Core Ideas

Mixed cropping facilitated the formation of a high‐efficiency canopy structure.

Mixed cropping delayed the rate of leaf senescence, maintained higher LAI and CAP during the grain filling period.

Mixed cropping increased aboveground dry matter weight at physiological maturity, and ultimately led to higher grain yield, especially medium density.

Polyacrylic Acid Modified Cerium Oxide Nanoparticles: Synthesis and Characterization as a Peroxidase Mimic for Non-Enzymatic H2O2 Sensor
Authors: Rattu Gurdeep , Khansili Nishtha , Krishna Prayaga M.
Published: December 2019

Background:

Cerium oxide nanoparticles (nanoceria) are efficient free-radical scavengers
due to their dual valence state and thus exhibit optical and catalytic properties. Therefore, the main
purpose of this work was to understand the peroxidase mimic activity of polymer-stabilized
nanoceria for enzyme-less H2O2 sensing by fluorescence spectrometer.

Objective:

This research revealed the development of fluorescence hydrogen peroxide nanosensor
based on the peroxidase-like activity of polyacrylic acid stabilized nanoceria (PAA-CeO2 Nps).

Methods:

PAA-CeO2 Nps were synthesized by simple cross-linking reaction at a low temperature
and characterized by XRD, SEM, Zeta potential, TGA, FT-IR and UV-VIS spectroscopic analysis.
H2O2 sensing was performed by a fluorescence spectrometer.

Results::

The synthesized polymer nanocomposite was characterized by XRD, SEM, TGA, FT-IR
and UV-VIS spectroscopic analysis. The XRD diffraction patterns confirmed the polycrystalline
nature and SEM micrograph showed nanoparticles having hexagonal symmetry and crystallite size of
32 nm. The broad peak of Ce–O bond appeared at 508 cm-1. UV-VIS measurements revealed a welldefined
absorbance peak around 315 nm and an optical band-gap of 3.17 eV. As synthesized PAACeO2
Nps effectively catalysed the decomposition of hydrogen peroxide (H2O2) into hydroxyl radicals.
Then terephthalic acid was oxidized by hydroxyl radical to form a highly fluorescent product.
Under optimized conditions, the linear range for determination of hydrogen peroxide was 0.01 - 0.2
mM with a limit of detection (LOD) of 1.2 μM.

Conclusion:

The proposed method is ideally suited for the sensing of H2O2 at a low cost and this
detection system enabled the sensing of analytes (sugars), which can enzymatically generate hydrogen
peroxide.

Authors: Anban J. Deva , Kumar J. Sharmi , James C. , Pradhan Sayantan
Published: December 2019

Background:

Local anesthetics are widely used to decrease sensitivity to pain in specific regions of the body while performing medical tasks. Many studies have probed the mechanism of action of local anesthetics but still many questions remain. (2R - (-) 2 - (2, 6-dimethylphenylaminocarbonyl) - 1 – methyl piperidinium chloride (DAMP), is an extensively used amide-type local anesthetic.

Objective:

This study aims at revealing the various electrophysical and chemical properties of the title compound. This study will be useful for future research by pharmacologists.

Method:

Density Functional Theory (DFT) computations were executed using Gaussian’09 program package and were optimized with the B3LYP /6-311+G (d, p) basis set. Natural bond orbital (NBO) analysis was carried out with version 3.1. Normal Coordinate Analysis (NCA) was used to systematically calculate the harmonic vibrational wavenumbers. Molecular docking simulations were carried out to understand the pharmacokinetic behavior of the drug.

Results:

The presence of strong N-H…Cl intra molecular hydrogen bonding was evidently revealed from the FT-IR spectrum due to the shifting of NH stretching wavenumber. Stability of the molecule arising from hyper conjugative interactions exhibits the bioactivity of the molecule by natural bond orbital analysis. The title molecule binds to the inner pore and blocks voltage - gated sodium channels in peripheral neurons.

Conclusion:

A detailed molecular picture of DAMP and its interactions were obtained by modeling analysis, IR, Raman, and UV-Vis spectroscopy. The geometrical parameters agree well with the XRD data. NBO analysis indicates the bioactivity of the molecule. The HOMO-LUMO energy gap indicates the possibility of intramolecular charge transfer of the molecule. From the ligand docking studies it is concluded that the title molecule binds to the inner pore and blocks voltage - gated sodium channels in peripheral neurons.
Nickel and Oxidative Stress: Cell Signaling Mechanisms and Protective Role of Vitamin C
Authors: Das Swastika , Reddy Rachamalla C. , Chadchan Kailash S. , Patil Arun J. , Biradar Mallanagouda S. , Das Kusal K.
Published: December 2019

Background:

Nickel activates the signaling pathways through the oxygen sensing mechanism and the signaling cascades that control hypoxia-inducible transcriptional gene expressions through oxidative stress. This review emphasizes on the recent updates of nickel toxicities on oxidant and antioxidant balance, molecular interaction of nickel and its signal transduction through low oxygen microenvironment in the in-vivo physiological system.

Discussion:

ickel alters intracellular chemical microenvironment by increasing ionized calcium concentration, lipid peroxidation, cyclooxygenase, constitutive nitric oxide synthase, leukotriene B4, prostaglandin E2, interleukins, tumor necrosis factor-α, caspases, complement activation, heat shock protein 70 kDa and hypoxia-inducible factor-1α. The oxidative stress induced by nickel is responsible for the progression of metastasis. It has been observed that nickel exposure induces the generation of reactive oxygen species which leads to the increased expression of p53, NF-kβ, AP-1, and MAPK. Ascorbic acid (vitamin C) prevents lipid peroxidation, oxidation of low-density lipoproteins and advanced oxidation protein products. The mechanism involves that vitamin C is capable of reducing ferric iron to ferrous iron in the duodenum, thus the availability of divalent ferrous ion increases which competes with nickel (a divalent cation itself) and reduces its intestinal absorption and nickel toxicities.

Conclusion:

Reports suggested the capability of ascorbic acid as a regulatory factor to influence gene expression, apoptosis and other cellular functions of the living system exposed to heavy metals, including nickel.

Authors: Gameaa Reham M. , Hawash Nehad , Badawi Rehab , Abd-Elsalam Sherief , Kasem Gamal K. , Wasfy El-Sayed A.
Published: December 2019

Background & Aim:

Simple hepatic steatosis is a benign condition, but it may cause serious liver damage as it may lead to steatohepatitis, fibrosis and cirrhosis. The Controlled Attenuation Parameter (CAP) of fibroscan assesses hepatic steatosis. The aim of this work was to assess hepatic steatosis in patients with chronic hepatitis B infection using FibroScan and to detect its relation to insulin resistance.

Methods:

Seventy-seven patients with chronic HBV were enrolled in this study. Body mass index, complete lipid profile, fasting insulin, HOMA-IR, pelviabdominal ultrasound and fibroscan were assessed in all patients.

Results:

According to the presence of significant steatosis, seventy-seven patients enrolled in this study were divided into different groups, such as group I 47 patients (61.04%) with CHB virus infection with non-significant steatosis and group II 30 patients (38.96%) with CHB infection with significant steatosis. There was a statistically significant increase in fasting insulin and HOMA-IR in group II (p-value <0.001). CAP results ranged from 100-396 db/m with no significant difference in liver stiffness measurements in two studied groups (P value= 0.886). There was a significant positive correlation between the degree of hepatic steatosis measured by fibroscan and fasting insulin blood level, HOMA-IR, serum cholesterol and LDL. At cutoff > 222 db/m steatosis measured by fibroscan had a sensitivity of 63.33% and specificity of 82.35% for the detection of insulin resistance.

Conclusion:

In CHB infected patients, steatosis measurement by fibroscan was a strong predictor of Insulin Resistance (IR) and vice versa.

In this paper, we have proved that the HDFS I/O operations performance is getting increased by integrating the set associativity in the cache design and changing the pipeline topology using fully connected digraph network topology. In read operation, since there is huge number of locations (words) at cache compared to direct mapping the chances of miss ratio is very low, hence reducing the swapping of the data between main memory and cache memory. This is increasing the memory I/O operations performance. In Write operation instead of using the sequential pipeline we need to construct the fully connected graph using the data blocks listed from the NameNode metadata. In sequential pipeline, the data is getting copied to source node in the pipeline. Source node will copy the data to next data block in the pipeline. The same copy process will continue until the last data block in the pipeline. The acknowledgment process has to follow the same process from last block to source block. The time required to transfer the data to all the data blocks in the pipeline and the acknowledgment process is almost 2n times to data copy time from one data block to another data block (if the replication factor is n).

Calibration of Digital Cameras for Mobile Mapping Purposes
Authors: Situmorang Parningotan Hasudungan
Published: December 2019

The development of the use of non-metric digital cameras in the form of action cameras for collecting geospatial data has become very useful and supports the work of mobile mapping for making three-dimensional (3D) models. Each lens has an error in the formation of a projection design and also an error during production. For example in a fisheye lens, which has a distortion model, namely radial distortion, tangential distortion, and shifting of the optical center point. The camera is considered to be calibrated if the principal distance, principal point offset, and lens distortion parameters are known. The preparation stage that needs to be done on the mobile mapping work in making 3D models is camera calibration. This research aims to determine the value of internal orientation parameters of a digital camera (action camera) that is used for mobile mapping purposes. Camera calibration in Photogrammetry aims to determine the geometric model of the camera described by Interior Orientation Parameters (IOP), including focal length, shifting principle point (PP), distortion, and other parameters. The calibration method used is the test field calibration. The calibration activities carried out on digital cameras are by measuring targets in the field using coded targets from Agisoft software. The calibration process is also carried out when processing photo data with Agisoft Photoscan Professional software. Camera calibration results using bundle adjustment on Agisoft Photoscan Professional software produce IOP (Interior Orientation Parameter) parameters, namely principal distance (C), principal point offset (Xp, Yp), and lens distortion parameters (K1, K2, K3, P1 , P2, B1, B2). Based on the results obtained, it can be concluded that Maximum Observational Radial Distance Encountered is 1 mm.
Development of Spatio-Temporal Database Prototype For Management of 4-Dimensional Cadastre Object In Indonesia
Authors: Sulistyawati Miranty Noor , Aditya Trias , Santosa Purnama Budi
Published: December 2019

The dynamics of the Indonesian population has increased causing the need for cadastral objects to increase. 2D and 3D cadastral objects change over time. Cadastral objects have spatial and juridical data changes every day. These changes can be caused by the transfer of rights, changes of rights, split and merging cadastral objects. Changes are recorded and stored as a history of cadastral objects (4-dimensional cadastre). Historical data on cadastral objects can be categorized as one of the big data in the cadastre sector, based on the frequency of recording data. The data can be used to track changes in cadastral objects so that they can avoid disputes. Spatial data in this case is very vulnerable data to cause disputes if the shape, position and size do not match the conditions in the field, and need special attention in integrating with the juridical data. This paper aims to identify methods for storing spatial data of 4D cadastral objects that are suitable for Indonesia. The importance of storing cadastral objects and their history causes researchers and cadastre experts in the world to formulate international standards in managing spatial and juridical data along with a history of cadastral objects (4D cadastre). LADM is an international standard conceptual model (ISO 19152) which can show the legacy of a cadastral object expressed in RRR (Rights, Restriction and Responsibility). In LADM, there is a VersionedObject class that represents various versions or a history of spatial units, object registration, owner and administration. Several studies conducted by researchers in the world were compared in this paper to find methods for applying LADM and VersionedObject classes. That methods were implemented in this paper to design a database of spatio-temporal 4D cadastre. Finally a prototype of spatial-temporal database will be produced to manage 4D cadastral objects.
Study of parcels-based Land Use Planning in Urban areas dan Rural Areas (Case Study of Mantrijeron Sub-district, Yogyakarta City and Bambanglipuro Sub-district, Bantul Regency)
Authors: Prabowo Hary Listantyo
Published: December 2019

The Land Use Planning (LUP-Neraca Penatagunaan Tanah/NPGT) is a balance between land availability and the needs of tenure, use and utilization of land according to the Regional Spatial Plan (RTRW) function area. LUP is arranged sectorally and regionally. Examples of sectoral LUP are rice field planning and plantation field planning. While regional LUP is arranged at a certain administrative level. So far LUP has been prepared based on zones/ regions that are adjusted to the RTRW functions area. The LUP at the sub-district administrative level began to be initiated and to be implemented after almost all of district/ city LUPs were implemented. Sub-district LUP was supported by the availability of the Subdistrict Spatial Detail Plan (RDTR) on a 1:5.000 scale which became a reference in the permittance of space utilization, so that the subdistrict LUP was arranged on the same scale. In this paper an assessment of sub-district LUP was made based on the Parcels Map (PBT) that available in the land office. PBT displays land parcels based on land ownership and land tenure. LUP is carried out in urban areas and rural areas. Location of urban areas in Mantrijeron Sub-District, Yogyakarta City, while rural areas in Bambanglipuro Sub-District.The stages of sub-district LUP consist of : data collection/ inventory; processing and analysis of data; and compilation of results and discussion. The data collection/ inventory phase includes activities for preparing work maps and collecting primary data and supporting data. The processing and analysis stage includes data processing on sub-district LUP compilation with GIS application (ArcGIS) and LUP analysis. LUP analysis consists of : analysis of land use changes, analysis of land use suitability and analysis of land availability. The stage of result preparation and discussion includes the preparation of the result of the analysis, a comparison between two regions that were studied, conclusions and recommendations. The result of the parcels-based sub-district LUP shows that land tenure and ownership information is very detailed; the information of land use and utilization in one parcel of land can consist of more than one type. In urban areas, the size of land parcels is relatively small with more varied types of land use and utilization than rural areas. As a note, that the coverage of parcels map in rural areas still needs to be improved because there are still empty areas.
[Book Review] Homegoing
Authors: Edwards Louise Ling
Published: December 2019

In Yaa Gyasi’s debut novel Homegoing, two sisters separated by circumstance are born in 18th-century Ghana not far from the Cape Coast Castle.  One sister, Effia, marries a white officer employed at the Castle and lives a comfortable life there with her husband and son.  The other sister, Esi, is captured during a raid on her village, marched to the Castle, and held in appalling conditions in its dungeons.  They reside in the castle together, yet without knowledge of the other’s presence or situation. The two sisters’ stories diverge when Esi is shipped to the southern plantations of the United States as part of the Trans-Atlantic Slave Trade.  The rest of the novel follows the two branches of the family through seven generations in portrait-like chapters that alternate between describing the descendants of Effia and those of Esi.  Not only does the story illustrate how the legacy of slavery impacts the two lineages generations after emancipation, but it describes an expansive scope of Black history and the relations between Africans and African-Americans through personal narrative. What is impressive about the tale is that it utilizes thorough and complex character development to move forward the histories of two nations over the span of 300 years.  The shortness of each characters’ individual story builds the intensity of each chapter packing every paragraph with emotion.  Understanding Gyasi’s deep personal connection to the story makes it clear why Gyasi was able to depict each character with such nuanced detail.  She is telling a fictionalized version of her own family history, based off of her experience straddling Ghana’s and America’s two histories.
Religious Leaders and Elections in the Polarizing Context of Indonesia
Authors: Ahnaf M. Iqbal , Lussier Danielle N.
Published: December 2019

Studies of elections in young democracies point to the risk of elections intensifying existing social conflicts, a process observed in Indonesia in recent years. The 2017 mayoral election in Yogyakarta contradicts this trend, presenting an empirical puzzle. Despite the fact that local conditions might encourage electoral mobilization along sectarian lines, we find evidence of restraint. Based on analysis of the contents of sermons in 12 mosques and churches in the month before the election we identify three factors that discourage religious leaders from exercising opportunities to intensify religious tension. These include (a) elites were not motivated to exacerbate communal tension because they do not feel the election will bring about reform or change that would seriously affect their established position, (b) even though sectarian messaging is possible, the elites did not believe masses could be easily persuaded by sectarian political messaging, and (c) political outbidding by using sectarian messages would risk confronting the local dominant culture of harmony. These findings suggest that several factors need to be activated for religious leaders to exercise their moral authority over worshippers for political purposes. The presence of an opportunity structure for intensifying sectarian conflict is not sufficient for that conflict to emerge.
Ethnic Identity: A Study of Construct Equivalence
Authors: Supratiknya Augustinus
Published: December 2019

This research aimed to examine the Multigroup Ethnic Identity Measure’s (MEIM 1992) adequacy to explore Indonesian youth’s ethnic identity. Hence MEIM 1992 was adapted into MEIM Indonesia through translation-back-translation method. Involving 448 (179 or 40% male and 269 or 60% female) students aged 17 – 28 years (Mean = 19.87; SD = 1.30) with different ethnic backgrounds in a private university in Yogyakarta as respondents, EFA with SPSS showed that the MEIM Indonesia measured one factor as MEIM 1992 does, CFA with R- studio showed that the one factor model fitted the data (factor loadings ranged from 0.323 to 0.750), its items had r it -s that ranged from 0.32 to 0.64, as a scale had a Cronbach’s alpha of 0.84, showed a concurrent validity coefficient r =0.23 (p < 0.01) with the RSeS Indonesia as a criterion, and was able to differentiate the levels of ethnic identity of sample pairs of Javanese, Bataks, Dayaks, Chinese, Florinese and a mixture of two or three ethnic groups. Hence, the MEIM Indonesia was conceptually and empirically proven to have construct equivalence with the 1992 MEIM as well as to show adequacy and was coined Skala Identitas Suku Bangsa (SISB).

Heidegger y el olvido de la retórica
Authors: Xolocotzi Yáñez Ángel
Published: December 2019

Este artículo se enfoca en la revisión de la Retórica de Aristóteles que Martin Heidegger ofreció durante el semestre de verano de 1924. Mi objetivo es destacar algunos aspectos de esa revisión que, a pesar de no haber repercutido mucho en el horizonte de la pregunta por el ser, contribuyen al redescubrimiento y revalorización del papel de la retórica no sólo para el planteamiento heideggeriano, sino en el ámbito filosófico contemporáneo en general. En concreto, se trata de la caracterización de la retórica como hermenéutica, como posibilidad, como escucha y, sobre todo, como la primera investigación acerca del λόγος entendido como lenguaje. El artículo busca destacar aspectos que no enfatizan otras interpretaciones en torno a las contribuciones de Heidegger respecto del llamado “giro retórico”.
Argumentos anticirenaicos en el programa cultural de la República de Platón
Authors: Mársico Claudia
Published: December 2019

Platón proyecta en la República un programa cultural que supone la redefinición del papel de la poesía tradicional en razón de su asociación con los regímenes democrático y tiránico. Esto, según pretendo mostrar, puede vincularse de manera legítima con la polémica anticirenaica de Platón contra Aristipo. Para ello, por un lado, exploraré los rasgos del biotipo tiránico y su régimen concomitante en la República VIII–IX y, por otro, analizaré sus vínculos con los planteamientos anticirenaicos en el Gorgias. Este examen permitirá ofrecer claves de análisis para dos pasajes muy discutidos de la República IX: el símil del ascensor y el número del tirano, que cobran una nueva luz a partir de la consideración de esta polémica intrasocrática.
Horkheimer, lector del positivismo. Un análisis crítico de la interpretación horkheimeriana del positivismo en sus textos tempranos
Authors: Gonzalo Adriana , García Cherep Paula
Published: December 2019

Este trabajo reconstruye la caracterización de “positivismo” en tres obras centrales de Horkheimer. Se afirma que, en el uso del término, Horkheimer incurre en una doble equivocidad, pues lo utiliza indistintamente para referirse al positivismo decimonónico y al del siglo XX; además, no reconoce las diferencias internas entre las posiciones de los positivistas contemporáneos. Asimismo, se muestra que muchos rasgos que se consignan como propios del positivismo del siglo XX no tienen justificación en los textos de esa tradición, de manera que la categoría horkheimeriana de “positivismo” se convierte en una entidad interpretativa respecto de la cual la Escuela de Fráncfort se considera antagónica. A partir de lo anterior se realiza una crítica a las interpretaciones del autor.
