“Estado/sociedad”: una anacronía regresiva
Authors: Saltalamacchia Homero Rodolfo
Published: October 2020

En el presente trabajo discutiré la pertinencia teórica y la convenien­cia política de seguir distinguiendo “estado” de “sociedad”. No creo que sea fácil supe­rar, en nuestro lenguaje, dicha dicotomía: como no lo es, por ejemplo, la que distingue cuerpo y alma. Pero, al menos, el intento servirá para saber qué afirmamos implícitamen­te al utilizarla. Por eso, al discutir la pertinencia actual de la misma sostendré que su uso ha conducido a  prosopopeyas que poco ayudan a la comprensión de la complejidad social: “El estado hizo…”, “El estado viola…”, “el estado está presente”, etcétera; pero que, más aún, es uno de los basamentos de la hegemonía capitalista, en tanto: a) muestra al estado como una entidad (“El Poder”, liberal dixit) que se distingue y domina a una sociedad ci­vil que se muestra como reservorio de asociaciones del más variado tipo, b) de ese modo, oculta que el estado es una relación que se dirime en todas las esferas de la vida y diluye la visualización de la principal forma de dominación, mostrándola como una simple sumatoria de productores que producen y/o intercambian mercancías junto otras asociaciones, que realizan diversas tareas de utilidad social; c) esa confusión permite a los sectores dominantes mostrarse como paladines de la sociedad civil y de la libertad frente al dominio estatal.Para dar algún soporte a esta interpretación, el trabajo se organiza del siguiente modo. En el primer apartado, haré una brevísima alusión a la literatura que hace del estado mo­derno una creación que emerge con las monarquías soberanas en Europa y que continúa hasta hoy; lo que me permitirá: 1) reclamar la necesidad de establecer las discontinuida­des correspondientes, a partir del cambio de la titulari­dad soberana; y, 2) mostrar el consecuente anacronismo de la oposición entre estado y sociedad, de origen iusnaturalista, cuando la soberanía pasó a los ciudadanos, borran­do las distancias existentes en la anterior formación estatal. Luego de esa discusión, el siguiente apartado promoverá el uso del concepto “estado” con referencia a las instituciones del estado/nación y, por ende yo proclamaré que el criterio principal de su tipologización debe el de las relaciones de fuerzas sociales que le dan forma en todas sus instituciones. Relaciones de fuerzas que se manifiestan, privilegiadamente, en la acción de los poderes electos (Ejecutivo y legislativo) y poderes no electos (Poder judicial y burocracias); pero también en las organizaciones no gubernamentales, cuyas principales corporaciones deberían ser consideradas dentro del derecho público, en aquellos aspectos de su actividad que impactan sobre la población.

Published: October 2020

Caulerpa racemosa merupakan salah satu jenis rumput laut yang memiliki prospek cerah untuk dikembangkan. Salah satu hal yang penting untuk diperhatikan dalam membudidayakan C. racemosa adalah kualitas air. Sehubungan dengan hal tersebut, diperlukan kajian terkait kualitas air pada tambak budidaya anggur laut selama masa pemeliharaan sebagai upaya untuk mengoptimalkan pertumbuhan anggur laut dan meminimalkan terjadinya kegagalan dalam usaha  budidayanya. Penelitian ini menggunakan metode survei, data primer dikumpulkan melalui observasi, dokumentasi, wawancara serta partisipasi langsung dalam kegiatan budidaya anggur laut (C. racemosa) di Balai Besar Perikanan Budidaya Air Payau (BBPBAP) Jepara, sedangkan data sekunder dikumpulkan melalui studi pustaka. Pengukuran kualitas air yang diukur selama masa pemeliharaan juga menunjukkan kondisi yang optimal bagi pemeliharaan anggur laut, hanya saja kadar nitrat terdeteksi dalam jumlah yang sangat kecil, namun hal ini tidak berpengaruh terhadap pertumbuhan C. racemosa. Hasil penelitian menunjukkan dengan suhu (30 - 31oC), DO (3.60 – 4.60 mg/L), pH (8.3 – 8.5), salinitas (39 – 40 ppt), NO3 (0 mg/L), PO4 (0,002 - 0,018mg/L). Laju pertumbuhan relatif pada anggur laut dengan metode sebar dasar didapatkan hasil 5 gr/hari. Untuk mengatasi kadar nitrat yang rendah, dalam masa pemeliharaan dapat dilakukan kegiatan pemupukan susulan dan peningkatan monitoring kualitas air agar menghasilkan anggur laut yang berkualitas dan mampu memaksimalkan produksi anggur laut.

Authors: Gupta Supriya , Kothainayagi B. , Pathak Avnish
Published: October 2020

Bhagandara (Fistula-in-ano) is well known cause of morbidity in all ages, gender and socio-economic status which has a promising treatment available with Ayurvedic practice of Ksharasutra (medicated setons). This is proven to have relatively lower rates of complications and recurrences. The standardised form of Apamarg Ksharasutra (Snuhi, Apamarg and Haridra churan) is been used for long and still considered the gold standard. However, difficulty in procurement, non-perennial availability of few of its constituents and challenging technique especially in complex cases has always encouraged the practitioners and researchers to come up with trial of other ingredients as per old literature like Sushruta Samhita and to modify the application techniques. This is an endeavour to venture into literature and compile such promising efforts.

Authors: Shanmugam Revathy Marimuthu , C Vinay , Gopalasamy Sathya , Shanmugam Chitra
Published: October 2020

BACKGROUND: Many noninvasive surrogate marker for Portal hypertension or for the presence or grade of esophageal varices were studied..Splenomegaly along with splenic congestion secondary to splenic hyperdynamic circulation is seen secondary to Portal hypertension in cirrhotic patients that can be quantified by elastography.
AIM:The aim of this study was to investigate whether spleen stiffness, assessed by TE, useful tool for grading chronic liver diseases and to compare its performance in predicting the presence and size of esophageal varices in liver cirrhosis patients.
METHODOLOGY:86 patients with cirrhosis and 80 controls underwent transient elastography of liver and spleen for the assessment of liver stiffness (LSM) and spleen stiffness (SSM) . Upper GI endoscopy done in all Cirrhotic patients.
RESULTS: Spleen stiffness showed higher values in liver cirrhosis patients as compared with controls: 58.2 kpa vs14.8 kpa (P < 0.0001) and also found to be significantly higher in cirrhotic patients compared with varices and those without varices (69.01 vs 42.05 kpa, P < 0.0001). Liver stiffness was also found to be higher in cirrhotic patients with varices when compared to patients without varices (38.5vs 21.2 kpa). Using both liver and spleen stiffness measurement we can predicted the presence of esophageal varices correctly.
CONCLUSION: Spleen stiffness can be assessed using transient elastography, higher value correlated well with liver cirrhosis and presence of esophageal varices although it couldn’t correlate with grade of Esophageal Varix. Combined assessment of spleen and liver stiffness had better prediction of presence of Esophageal Varix.

Published: October 2020

Background: About 70% of persons with mental illness (PWMI) live in their families, with elderly family members assuming the role of caregivers.
Aims: To screen for depression and associated sociodemographic and illness-related variables, among elderly caregivers of PWMI.
Materials: Caregivers above the age of 60 years of PWMI were assessed by Geriatric Depression Scale- Short Form (GDS-SF), Multiphasic Inventory for Perceived Social Support (MSPSS) and WHO – QOL Bref.
Results: 64% of the caregivers were screened positive for depression. Even though 92.5% had moderate to high PSS. Low PSS was significantly related to depression(p=0.001). The mean(SD) QoL score was 52.02(11.402). These two variables predicted 41.1% of the possibility of depression and PSS was more associated with caregiver depression.
Conclusion: Understanding the prevalence of depression and the various associated factors is important to plan for interventions that can have an indirect impact on the care of the PWMI.

Published: October 2020

Considerando a relação entre a festa e o espaço urbano e tendo como referencial empírico o Círio de Nossa Senhora de Nazaré, patrimônio cultural da humanidade, realizado em Belém do Pará, o presente artigo tem como objetivo discutir e propor uma análise acerca do Círio de Nazaré no processo de produção do espaço, observando os efeitos de sua mercantilização na dinâmica de apropriação urbana durante o período festivo. Para tanto, foi utilizado como procedimento metodológico o levantamento bibliográfico de obras que tratam da festa, cotidiano e produção do espaço na perspectiva lefebvreana, bem como sobre o Círio de Nazaré. A análise mostra que a festa interfere no espaço urbano, tanto temporária, quanto permanentemente, principalmente ao ser realizada segundo a lógica do mercado, em especial pela sua turistificação, podendo ampliar ou reduzir as possibilidades de exercício do direito à cidade dos habitantes e visitantes.
Interações Geomorfológicas e Ecológicas na Bacia Hidrográfica do Ribeirão Ubá (MG)
Authors: Silva Felipe Pacheco
Published: October 2020

Considerando a importância de abordagens interdisciplinares no âmbito das ciências ambientais, esse trabalho busca estabelecer uma análise integrada de componentes ecológicos e geomorfológicos para a Bacia Hidrográfica do Ribeirão Ubá. Essa bacia reúne um quadro altamente ilustrativo para a gestão de rios, dispondo de uma rica diversidade de ambientes geomorfológicos e atividades antrópicas que direcionaram modificações no sistema fluvial. Desse modo, a análise integrada permitiu identificar as interrelações entre os aspectos ecológicos e geomorfológicos, sobretudo, para os segmentos próximo às cabeceiras e impactados pelo lançamento de efluentes não tratados. Os resultados expõem o peso das modificações antrópicas no leito e, desse modo, as relações com as recorrentes inundações que acometem o sítio urbano, assim como a degradação ambiental de nichos ecológicos ao longo do curso, resultando em um quadro de assoreamento, eutrofização e contaminação por efluentes urbano-industrias não tratados. Nesse sentido, a investigação permitiu identificar importantes desafios para a gestão hidrográfica da área, assim como a importância de se compreender os processos fluviais e ecológicos de maneira conjunta, assim como o potencial da análise desses processos como sólidos indicadores ambientais.

Published: October 2020

O artigo indicia hegemonias e resistências em pequenas cidades no Nordeste brasileiro, analisando o caminhar na franja urbana que separa/vincula as cidades Redenção e Acarape, na Região do Maciço de Baturité, no estado do Ceará, os nomes das cidades e a emergência de novas juventudes e conflitos no cotidiano urbano. Buscamos assim revelar indícios do urbano hegemônico, assim como resistências e práticas alternativas na produção social do espaço urbano. A implantação da UNILAB em Redenção e em Acarape, em 2011, incorporou ao cotidiano urbano, em larga escala, uma população residente jovem, negra, indígena, africana, quilombola e feminina que, a priori, não se encontra inserida na cidade hegemônica e, mais do que isso, tensiona as espacialidades e as práticas hegemônicas da/na cidade. O percurso metodológico trilhado originou-se de pesquisas que mobilizaram dados secundários e geraram dados primários, através de análise documental, entrevistas, questionários e observação de campo de caráter etnográfico.

Paulo Freire, a filosofia e a vida
Authors: Kohan Walter Omar
Published: October 2020

Muitos estudos destacam as influências filosóficas que teria recebido Paulo Freire no decorrer de sua vida. Ao mesmo tempo em que se discute se ele é um filósofo, inúmeros estudos, no Brasil, mas, sobretudo no exterior, procuram identificar “a filosofia de Paulo Freire”, entendendo por tal os pressupostos filosóficos que possam explicar melhor suas ideias. Neste artigo, fazemos diferentemente. A partir de uma leitura proposta por M. Foucault, inserimos Paulo Freire numa tradição filosófica iniciada por Sócrates e os antigos Cínicos, em que o problema central é a vida como “uma forma de ser e ao mesmo tempo como uma forma de ética e heroísmo” (FOUCAULT, 2011, p. 196). Como resultado, oferecemos um Paulo Freire cuja vida não pode ser separada de seu pensamento, e sua vida filosófica é, ela própria, sua principal força educadora.

Authors: Hussain Najah A. , Sabbar Amal A.
Published: October 2020

Carlson’s Trophic State Index (CTSI) was applied to assess the trophic status of two kind of southern Mesopotima marshes. Six stations were selected, three in non-tidal Chebiyesh marshes and other three in tidal East Hammer marsh. The results indicated that the values of CTSI of the six stations fluctuated between 47.59 - 61.96 ranged from mesotrophic to Eutrophic. The increase of salinity during 2018 drastically affect CTSI values in East Hammer marsh. In general, both tidal and non-tidal marshes were eutrophic mainly due to direct release of untreated domestic swage and agricultural drainage waters. Trophic status of southern Iraqi marshes potentially impacted by transparency of the marsh, chlorophyll a and phospharus concentrations.

Published: October 2020

Introduction: Diabetes Mellitus has become one of the common metabolic disorders characterized by hyperglycemia, associated with deficiency or resistance to insulin and shows abnormality in exocrine activity of pancreas. Pancreas is mixed gland that is both an endocrine and an exocrine gland with clusters of endocrinal, islet cell dispersed among exocrine acinar cells. Defects in islets cells in diabetes effect the exocrine secretion of the pancreas.

Methods: Hospital based case-control study was conducted. Total sample size was 388. Out of which 194 were known cases of type 2 diabetic patients attending Manipal Teaching Hospital for medical checkup whereas 194 were Non Diabetic individuals with age and sex matched. Self-administer question was used to collected data from case and control. Three ml fasting blood samples were collected and centrifuged. Serum amylase was analyzed by using a semi automated analyzer. All estimates data were analysis statistically by using SPSS 22.0 full version.

Results: Serum amylase levels were found significantly low in diabetic patients as compared to the Non-Diabetic

(r = -0.313, p-value <0.001). Similarly, present study also showed negative correlation between serum amylase levels and duration of diabetes with Non-Diabetic (r = -0.388, p <0.001). Status of serum amylase and fasting sugar level was found to different among age groups, sex and ethnic groups.

Conclusions: The increasing in duration of diabetes decreases the level of serum amylase which suggests a possible exocrine-endocrine relationship in this disease. Similarly, the level of serum amylase and fasting blood sugar vary among age group, sex and ethnicity. Thus, measurement of serum amylase can be an additional informative parameter for the assessment of chronicity and progress of the illness as well as the response to therapy.

The hydrofluorocarbon 245 isomers, 1,1,1,3,3-pentafluoropropane, 1,1,1,2,2- pentafluoropropane, and 1,1,1,2,3-pentafluoropropane (HFC-245fa, HFC-245cb, and HFC-245eb) were activated through C–F bond activations using aluminium chlorofluoride (ACF) as a catalyst. The addition of the hydrogen source Et3SiH is necessary for the activation of the secondary and tertiary C–F bonds. Multiple C–F bond activations such as hydrodefluorinations and dehydrofluorinations were observed, followed by hydroarylation and Friedel–Crafts-type reactions under mild conditions.

The electronic properties of carbenes including thermodynamic parameters such as new electronic philicity indices Ie, Ph, and for comparizon chemical hardnesses η, proton affinities (РA) calculated by DFT method (B3LYP5/6-31G*/RHF for definition of electronic indices and B3LYP5/3-21G/RHF, B3LYP5/3-21G/UHF for definition of chemical hard¬nesses) have been discussed in the paper. With their help, the estimation of philicities, electron-donating and electron-withdrawing abilities of a wide range of carbenes of both nucleophilic and electrophilic type was carried out. It was established that the philicities of carbenes according to electronic indices Іе, Ph depend on the carbenic structure (the backbone of the molecule and steric effects of substituents) and also on the reagent structure, particularly its steric effect. For typical nucleophilic carbenes, the Ph is in the range of 1–3,0, for neutral carbenes 1–1,5, IeH 8,5–22,2 eV, for neutral carbenes IeH 8,5–10,5, for typical electrophilic – in the intervals of PhH –0,3–0,5, IeH –3,4–3,4 eV. The intermediate values (Ph 0,5–1,0, IeH 3,4–8,5 eV) are characteristic for typical ambiphilic carbenes. In the evaluation of electron-donating and electron-withdrawing properties, the values of ED and EA should be taken into account (maximal EDH values were found for neutral carbene 20 (13,8 eV) and for superbasic anionic carbenes (for 22 18,4 eV)). The highest electron acceptability EAH was found for cationic carbene 29 (11,8 eV). In the reactions with carbon ions, the values of the IeH, PhH indices decrease significantly, and the electron acceptability increases. Increasing the steric effects leads to «inversion» of philicities for nucleophilic carbenes (Ph up to 0,1), and the properties of electrophilic carbenes become even more pronounced (Ph up to –2,7). The found dependences of the electronic properties of carbenes allow regulating the structure of carbenes to achieve certain characteristics, which together with stability factors can be used in the design of structures for synthesis and practical application.

The increase of health and environmental consciousness has motivated the effort of technology improvement on lubrication by finding and exploring another potential alternative to replace mineral-based metalworking fluids. Due to this concern, vegetable-based oils have been recognised as an ideal lubricating base oil in machining due to low toxicity, biodegradable, and renewable energy sources. Moreover, nanofluids have attracted enormous attention in the field of lubrication due to excellent physical and chemical properties that can enhance tribological characterisation. The objective of the current work is to develop a new formulation of nanofluids in modified jatropha oil (MJO) by adding hexagonal boron nitride (hBN) and graphene nanoparticle additives at the lowest concentration (0.01, 0.025. and 0.05 wt. %). The physicochemical tests in terms of kinematic viscosity and viscosity index were conducted and compared with synthetic ester (SE). Tribology testing was conducted through four-ball test to determine the coefficient of friction, mean wear scar diameter, and friction torque. The result shows a significant improvement of MJO samples by adding nanoparticle additives compared to the SE. MJOg2 (MJO + 0.025 wt. % of graphene) exhibited excellent tribological behaviour by providing the lowest coefficient of friction and friction torque. Meanwhile, MJOh1 (MJO + 0.01 wt. % of hBN) provided with a smaller mean wear scar diameter among other lubricant samples. Conclusively, the addition of nanoparticle additives significantly enhanced the tribological characteristics and is highly suitable as a substitute for SE.

A linear stability evaluation is conducted to explore the effect on the onset of Marangoni-Bénard convection in a ferrofluid layer system. The system is heated from below with treatment of both the lower and upper boundaries to completely insulate the temperature disturbance. The eigenvalue problem is solved by using regular perturbation technique to obtain the critical number of Marangoni and also the critical number of Rayleigh. It is observed that the increase in the value Crispation, the magnetic number of Rayleigh and also the magnetic number will destabilize the system while the increasing number of Bonds will delay the convection.
Estimating the Ages of FGK Dwarf Stars through the Use of GALEX FUV Magnitudes

Published: October 2020

Stellar age cannot be directly measured, yet age determinations are fundamental to understanding the evolution of stars, planets, and galaxies. The work presented here builds upon the idea of a stellar-activity age. We utilized far-ultraviolet (FUV) photometry acquired by the Galaxy Evolution Explorer (GALEX) space telescope as an indicator of chromospheric activity to infer ages of late-F, G, and K type dwarf stars. We derived a purely empirical correlation between FUV magnitudes and stellar age in conjunction with (B − V) color. Our attention is restricted to Sun-like stars with color range

and absolute magnitude range 4.3 ≤ M
V ≤ 5.3. The correlation is defined in terms of a FUV-excess parameter

. We related stellar age, τ, to Q through the relation

, where a and b are fit parameters and functions of (B − V). This correlation is functional up to 6 Gyr for FGK dwarfs. With such a correlation, one only needs Johnson (B − V) and FUV measurements to estimate the stellar age for Population i dwarf stars of solar-like temperature and metallicity. Such a calibration has utility in population studies of FGK dwarfs for further understanding of the chemical evolution of the Milky Way. As an illustration of one such application, we have constructed activity and FUV–age distributions for a sample of thin and thick disk stars, as distinguished by their chemical abundances. Considerable overlap is found between the activity distribution and age range of the two populations. We discuss the possibility that some high-[α/Fe] thick disk stars were formed as a result of the accretion of dwarf galaxies as recently as 4 Gyr ago.
Swift/BAT and RXTE/ASM Observations of the 35 day X-Ray Cycle of Hercules X-1
Authors: Leahy Denis , Wang Yuyang
Published: October 2020

Swift/BAT and RXTE/ASM observations have monitored the X-ray binary system Her X-1 for approximately 14.5 yr each, and both were monitoring Her X-1 for a period of ∼5.5 yr. Here we study the 35 day cycle using these observations. Using a cross-correlation method we find the times of peaks of the 35 day cycles for ∼150 cycles observed by Swift/BAT and ∼150 cycles observed by RXTE/ASM. These cycles include ∼60 observed with both instruments. The noise level of the RXTE/ASM measurements is larger than that of Swift/BAT, resulting in larger uncertainty in peak times. The distribution of 35 day cycle lengths can be fit with a Gaussian with mean 34.79 days and σ of 1.1 days. The distribution of orbital phases of 35 day cycle peaks is well fit by a uniform distribution, with 76% of the cycles, plus a Gaussian distribution peaked at orbital phase ∼0.5, with 24% of the cycles. We construct the long-term average 35 day lightcurve in the 15–50 keV band from Swift/BAT, and in the 2–12 keV band from RXTE/ASM. The high-energy band shows more variability in the short high state and the low-energy band shows more variability in the main high state. This is consistent with a precessing accretion disk model as the cause of the 35 day cycle.

The properties of galaxy clusters as a function of redshift can be utilized as an important cosmological tool. We present initial results from a program of follow-up observations of the Sunyaev–Zeldovich effect (SZE) in high-redshift galaxy clusters detected by the Massive and Distant Clusters of WISE Survey (MaDCoWS) which uses infrared data from the Wide-field Infrared Survey (WISE) instrument. Using typical on-source integration times of 3–4 hr per cluster, MUSTANG2 on the Green Bank Telescope was able to measure strong detections of SZE decrements and statistically significant masses on 14 out of 16 targets. On the remaining two, weaker (3.7σ) detections of the SZE signal and strong upper limits on the masses were obtained. In this paper we present masses and pressure profiles of each target and outline the data analysis used to recover these quantities. Of the clusters with strong detections, three show significantly flatter pressure profiles while, from the MUSTANG2 data, five others show signs of disruption at their cores. However, outside of the cores of the clusters, we were unable to detect significant amounts of asymmetry. Finally, there are indications that the relationship between optical richness used by MaDCoWS and SZE-inferred mass may be significantly flatter than indicated in previous studies.
Empirical Test for Relativistic Kinetic Theories Based on the Sunyaev–Zel’dovich Effect
Authors: Molnar S. M. , Godfrey J.
Published: October 2020

We propose a new method to determine the electron velocity (EV) distribution function in the intracluster gas (ICG) in clusters of galaxies based on the frequency dependence of the Sunyaev–Zel’dovich (SZ) effect. It is generally accepted that the relativistic equilibrium EV distribution is the one suggested by Jüttner. However, there is an ongoing debate on the foundation of relativistic kinetic theory, and other distributions have also been proposed. The mildly relativistic ICG provides a unique laboratory to test relativistic kinetic theories. We carried out Monte Carlo simulations to generate SZ signal from a single-temperature gas assuming the Jüttner EV distribution assuming a few percent errors. We fitted SZ models based on nonrelativistic Maxwellian, and its two relativistic generalizations, the Jüttner and modified Jüttner distributions. We found that a 1% error in the SZ signal is sufficient to distinguish between these distributions with high significance based on their different best-fit temperatures. However, in any line of sight (LOS) in a cluster, the ICG contains a range of temperatures. Using our N-body/hydrodynamical simulation of a merging galaxy cluster and assuming a 1% error in the SZ measurements in an LOS through a bow shock, we find that it is possible to distinguish between Jüttner and modified Jüttner distributions with high significance. Our results suggest that deriving ICG temperatures from fitting to SZ data assuming different EV distribution functions and comparing them to the temperature in the same cluster obtained using other observations would enable us to distinguish between the different distributions.
Evolution of the Density PDF in Star-forming Clouds: The Role of Gravity
Authors: Jaupart Etienne , Chabrier Gilles
Published: October 2020

We derive an analytical theory of the PDF of density fluctuations in supersonic turbulence in the presence of gravity in star-forming clouds. The theory is based on a rigorous derivation of a combination of the Navier–Stokes continuity equations for the fluid motions and the Poisson equation for the gravity. It extends previous approaches, first by including gravity and second by considering the PDF as a dynamical system, not a stationary one. We derive the transport equations of the density PDF, characterize its evolution, and determine the density threshold above which gravity strongly affects and eventually dominates the dynamics of turbulence. We demonstrate the occurrence of t
wo power-law tails in the PDF, with two characteristic exponents, corresponding to two different stages in the balance between turbulence and gravity. Another important result of this study is to provide a procedure to relate the observed column density PDFs to the corresponding volume density PDFs. This allows us to infer, from the observation of column densities, various physical parameters characterizing molecular clouds, notably the virial parameter. Furthermore, the theory offers the possibility to date the clouds in units of t
coll, the time since a statistically significant fraction of the cloud started to collapse. The theoretical results and diagnostics reproduce very well numerical simulations and observations of star-forming clouds. The theory provides a sound theoretical foundation and quantitative diagnostics to analyze observations or numerical simulations of star-forming regions and to characterize the evolution of the density PDF in various regions of molecular clouds.
