Authors: Samadi Hamid Reza
Published: January 2022

Ramsar area is located across and between Alborze Mountain and Caspine Sea in North of Iran. About 30 spas are located south of the Ramsar and Sadatshar town. They are almost in between 20 to 70 m elevation. Paleozoic, Mesozoic and Tertiary rocks and alluvial deposit are exposed around the Ramsar area. In tertiary, acidic Plutonism was active and intrusion into the Paleozoic and Cenozoic formations. Quaternary and Alluvium deposits are exposed and extending on the Jurassic formations in Ramsar plain and have thickness lower than 10 m in show springs. The annual precipitation in the Ramsar region is 976 mm. There has not any proper Thermal spring management in Ramsar area yet. This could post some serious problem on improper management of Thermal spring sites, where its environment has been put into jeopardy. This study aims to provide a way to classify the Thermal springs in Ramsar area. The result of this study help in the classification of Thermal spring sites for official planning improvement of administration and sustainable development of natural resources of the area. The study makes use of the Department of Applied Geosciences in Islamic Azad University. GIS data of a total of 9 Thermal springs in the attempt to set up a classification system of Thermal springs in Ramsar area. These data include surface temperature, conductivity, alkalinity, acidity, TDS, pH values, H2S, Ca, Cl, Fe, K, Mg, Mn, Na, SiO2, SO4 contents, their locations, usages and other relevant information. The surface temperature of Thermal springs are between 19oC – 65oC and Na-K-Cageothermometer shows estimated reservoir temperature range from 25 o C – 195 o C. Most of the water from these Thermal springs is relatively turbidness and their composition is sodium choloride. The Thermal springs in this area generally exhibit high SiO2 and Na content; strong smell of sulfur. In addition, there are 9 Thermal springs that show high concentration of Cl, Ca, Na, K and Mg. There are three major criteria used in the classification system in this study, temperature, pH and their usage. On the basis of temperature, there are three classes of Thermal springs in Ramsar area: hyper thermal spring (10 %, 50-99o C); thermal spring (80%, 30-50o C). There is one class achieved on the basis of pH values: all of Thermal springs exhibit weak acids. There are 4 types of usage classification: swimming pools, Tourism, space heating and drying of organic materials.
The Bounds of Time Lag and Chemotherapeutic Efficacy in the Control of HIV/AIDS
Authors: Titus Rotich K , Robert Lagat C
Published: January 2022

The current use of Highly Active Anti-Retroviral Therapy (HAART) strategy to control Human Immunodeficiency Virus (HIV) and Acquired Immune Deficiency Syndrome (AIDS) is inefficient in eradicating HIV/AIDS due to inadequate understanding of the dynamics relating to interaction between the immune system components and HIV. As a result, a pool of potential transmitters is continuously created and thus HIV has remained a pandemic. In this paper, we formulate a mathematical model using differential equations to study the effects of time lag τ>0 due to cellular latency and pharmacological delays and chemotherapy on the control strategy of AIDS epidemic. Equilibrium points of the model are computed and used to determine the reproductive ratio〖 R〗_0. This important threshold parameter is then used to determine the critical bounds of time lag τ∈[τ_min,τ_min] and therapeutic window C_p∈[MEC,MTC] that is, the bounds; above Minimum Effect Concentration (MEC) and below Minimum Toxic Concentration (MTC), where drug plasma concentration C_p should lie for effective maintenance of low levels of viral load and reduction of drug toxicity. The mathematical model gives qualitative understanding of HIV prognostic information which is a means of rejuvenating the existing Antiretroviral drugs (ARV’s). Numerical simulations show that a stable and persistent endemic equilibrium state of low viral load is achieved when these thresholds τ∈[0,25] and C_p∈[0.79,0.91] are satisfied. This persistent equilibrium state will lead to eventual eradication of HIV/AIDS.

The investigation was carried out using LiF TLD discs Reader, TLD model 4500 (Harshaw Radiation measurement product USA), 3-phase diagnostic X-ray machine and single a phase X-ray machine. The Mean testicular dose of the male patients investigated was found to be 0.0662±0.0034mGy. There is also a significant correlation between testicular dose and tube potential, in which higher tube potential delivered higher values of testicular doses. Results showed that, testicular doses are within acceptable limits, which is approximately 6.6% of the 1mGy reference dose level.
Does the Propolis Reinforce the Autoclaved Bone Allograft and Does it Have an Immunomodulation Effect?
Authors: Boudra Abdellatif
Published: January 2022

The loss of bone substance in diaphyseal region of long bones is a common problem faced by veterinarian orthopedic surgeon. In order to recover from cortical bone defect our study proposes to implant an autoclaved orthotopic allograft of one centimeter length and compares effects of covered and uncovered bones with propolis in the femoral diaphysis under general anesthesia and sterile condition. The experiment involved eight adult dogs, from local breed and different sex; split into two groups. An autoclaved allograft without propolis was implanted for the first animals group (control group ) then the same graft has been implanted to the second animals group. The aim of our study is to determine whether the propolis resin can diminish the fragility of autoclaved allografts that was confirmed by the resistance of the graft covered with propolis even once the osteosynthesis material is removed and if the autoclaved grafts covered by the propolis used in our experiments have not suffered resorption despite the intensity of the immune response during the first month.The results show that all grafts covered with propolis remained unbroken and have not suffered of the resorption problems.

Published: January 2022

Recent progress of chromium complex pre-catalysts in ethylene oligomerization and polymerization is reviewed herein. As well as the well-established trimerization of ethylene by chromium catalytic systems, such pre-catalysts have more generally been explored for ethylene oligomerization. Furthermore, chromium complex pre-catalysts have been found to exhibit high activity during ethylene polymerization. The catalytic activities can be influenced by the nature of ligands present, which can provide useful knowledge in determining structure-activity relationships. This review provides collective references concerned with the design of complex pre-catalysts with a view to ethylene reactivity.

Published: January 2022

The demand for goat milk has gradually increased in Turkey in recent years and dairy goat breeding began to be seen as an alternative investment area. The aim of the study is to create the data that will contribute to policy formulation in the stockbreeding industry by making a 10-year forecast of output pertaining to the goat milk production in Turkey. In the study, the annual data of the goat milk production in Turkey during the time period 1961 and 2016 obtained from Turkish Statistical Institute and Food and Agriculture Organization was utilized. Box-Jenkins estimation models and artificial neural networks model were used to forecast the production of goat milk. It was identified that artificial neural networks model gave the best result and prospective estimations were made through this model. As a result of the study, the projected value of milk production for 2026 was found to be 495,536.1 tons. Following the forecasts, it was calculated that the average rate of increase in the goat milk production will be 0.12%.

Published: January 2022

Bovine livestock is one of the most important economic and social sectors for many countries. In this sense, the development of strategies to improve reproductive bull fertility and reproduction rates is relevant. It's highlighted the role of seminal plasma proteins (SPP) in reproductive fertility, so it has found close relationships among studies on the structure and biological activity of SPP, with seminal quality, including viability, sperm motility, and morphology. In addition, they have been found to regulate sperm functions such as capacitation, acrosome reaction, and they are even related to protecting sperm against thermal and oxidative stress. Moreover, the methods of separation and protein identification and their contribution to characterizing the bovine SP proteome should be also highlighted. In this sense, the most recent studies have been directed towards developing supplements with SPP that improve quality sperm subjected to cryopreservation processes. Research has begun and should forward to establish how the networks or sets of proteins are related to the functioning and fertility of sperm, the search for biomarkers of fertility, and the use of proteins in biotechnological processes, to increase efficiency reproductive.

In vitro embryo production (IVEP) is used to develop high-quality genetics associated with intergenerational genetic gain. It is characterized by acquisition (in vivo or post-mortem) and maturation (MIV) of oocytes from donors, followed by fertilization (FIV) of matured oocytes and culture (IVC) of embryos, which are then sent to transferred or cryopreserved. Even with extensive knowledge on IVEP, some biochemical and hormonal regulations that involve embryonic development are still unknown, leading to a low overall efficiency of the biotechnological process. Although in vitro developed embryos have a lower quality than that produced in vivo, in terms of resistance to challenging events, IVEP presents itself as a potential biotechnology. In cattle breeding, reproductive biotechnologies are key to increase and improve the genetic improvement of the herd, associated with productive and reproductive efficiency. In this article, the steps and strategies of IVEP and its contribution to reproduction in the cattle sector are discussed.

Published: January 2022

This study aimed to evaluate population parameters, genetic diversity and identify the ancestors with the highest genetic contribution of an open population of Silla Argentino horses in Colombia using pedigree data. 508 horses born between 1998 and 2018 were evaluated, called reference population (RP). The ancestors of the RP were added, defining the total population (TP) whit 1,861 horses born since 1905. Population parameters were estimated, including inbreeding coefficient (F), effective population size (Ne), effective number of founders (fe), ancestors (fa), and founder genomes (fg) and generation interval (GIN). The GIN was 10.1 (TP) and 7.7 (RP) years. The estimate of F for the RP was 0.3%, indicating control in mattings. The Ne was 317 (RP) and 179 (TP). The probability of genes origin indicated values for fe, fa and fg of 386, 187 and 351 (TP), and 161, 64 and 56 (RP), respectively, evidencing a reduction of genetic variability in the RP. Half of the genetic variation in the equine population studied was explained by 40 ancestors. The results show loss of genetic diversity in the RP and the genetic contribution of the ancestors suggests the need to increase the number of stallions for breeding and guide mating to increase genetic diversity in the new generations of Silla Argentino horses of the Colombian National Police

Published: January 2022

Background. Biodegradable polymers are one of the most promising groups of materials suitable for creating tissue-engineered scaffolds. The high interest in biopolymers is associated with the possibility of creating scaffolds with desired properties, through the use of mixtures and copolymers. The determination of the key parameters of biocompatibility is the basic purpose for testing created materials.

Objective. To perform the comparative in vitro study of biocompatibility properties of biopolymer scaffolds produced using polycaprolactone, polylactic acid, their mixtures and copolymers by electrospinning technology.

Design and methods. The adhesion properties and cytotoxicity of scaffolds made from polycaprolactone, polylactic acid, copolymer of L- and D-isoforms of lactic acid, their mixtures and co-polymers with the addition of polyglycolic acid were investigated after scaffolds co-cultivation with human mesenchyme stem cells (MSC).

Results. The largest number of spread spindle-shaped MSCs was on the surface of polymers containing polyglycolic acid. Besides, the cells on the surface of the copolymer with polyglycolic acid had the morphology closest to the control. The lowest number of living cells was found on the surface of polylactic acid scaffolds, and the highest on the surface of samples from of polycaprolactone and polylactic acid blend.

Conclusion. Thus, all tested polymers had good adhesion properties in experiments with human mesenchyme stem cells were possessed by biodegradable polymers with the addition of polyglycolic acid.

Published: January 2022

Background. Application of a biomarker panel during the acute period of the ischemic stroke (IS) can contribute to a more accurate and prompter diagnostics and verification of the optimal approach to a patients’ management.

Objective. We aimed to clarify values of neuron-specific enolase (NSE), glial fibrillar acidic protein (GFAP) and antibodies for NMDA receptor’s NR2-subunit (NR2-antibodies) in the acute period of IS, to compare with such values in patients without IS, to assess their relationship with severity of neurological deficit and short-term outcome and also to establish sensitivity and specificity of the biomarker panel.

Design and methods. 63 patients with IS and 31 people (11 with chronic brain ischemia and 20 healthy individuals) as controls were included. Results. NSE and GFAP values in IS group exceeded reference values at the onset of disease, lowering significally by 10-14 day, while NR2-antibodies’ values were lower at the onset of the disease compared with controls, rising by 10-14 day. In patients with unfavourable short-term outcome higher levels of NSE, GFAP and NR2-antibodies were found. A panel of such biomarkers has higher sensitivity and specificity than each of them individually.

Conclusion. Researched substances can be used in a biomarker panel for IS diagnostics, brain damage monitoring, patient’s condition evaluation and short outcome prognosing.
A Biographic Researcher in Pursuit of an Aesthetic: The use of arts-based (re)presentations in “performative” dissemination of life stories
Authors: Jones Kip
Published: January 2022

The (re)presentation of biographic narrative research benefits greatly from embracing the art of its craft. This requires a renewed interest in an aesthetic of storytelling. Where do we find an aesthetic in which to base our new “performative” social science? The 20th Century was not kind to 18th Century notions of what truth and beauty mean. The terms need to be re-examined from a local, quotidian vantage point, with concepts such as “aesthetic judgment” located within community. Social Constructionism asks us to participate in alterior systems of belief and value. The principles of Nicolas Bourriaud’s Relational Aesthetics offer one possible set of convictions for further exploration. Relational Art is located in human interactions and their social contexts. Central to it are inter-subjectivity, being-together, the encounter and the collective elaboration of meaning, based in models of sociability, meetings, events, collaborations, games, festivals and places of conviviality. Bourriaud believes that Art is made of the same material as social exchanges. If social exchanges are the same as Art, how can we portray them? One place to start is in our (re)presentations of narrative stories, through publications, presentations and performances. Arts-based (re)presentation in knowledge diffusion in the post-modern era is explored as one theoretical grounding for thinking across epistemologies and supporting inter-disciplinary efforts. An example from my own published narrative biography work is described, adding credence to the concept of the research report/presentation as a “dynamic vehicle”, pointing to ways in which biographic sociology can benefit from work outside sociology and, in turn, identifying areas of possible collaboration with the narrator in producing “performances” within published texts themselves.
Benefic organisms in agricultural crops: Towards a safety and healthy food in response to COVID-19 and future syndemics
Authors: Samaniego-Gaxiola José Alfredo
Published: January 2022

A population with an adequate immunity is key to reduce the effects of COVID-19. Moreover, a healthy diet and an innocuous environment are factors for an adequate immunity. Healthier and more innocuous foods could be obtained with the extensive use of beneficial organisms on agricultural crops, helping reduce the use of agrochemicals and increasing the tolerance of plants to stress caused by abiotic and biotic factors. Nitrogen-fixating bacteria or free-living bacteria, mycorrhizae, endosymbiotic microorganisms, endophytes, entomopathogenic fungi and bacteria, pest predators and parasitoids, hyper parasitic viruses of pests and pathogens are some of the organisms that can induce the natural suppression of parasites, fixate nitrogen and optimize the capture of nutrients and water, among other ecosystemic benefits. This revision presents functions and properties of beneficial organisms and proposals are made for their use to benefit farmers and consumers, with the intention of contributing to the productive processes towards a sustainable agriculture.

Published: January 2022

COVID-19, a pandemic disease caused by SARS-CoV-2, changed the production schemes and supply chains in all spheres of the world’s economy. The agricultural sector in Mexico was no exception, although it has been so essential during the pandemic that its growth was higher than the other sectors of the Mexican economy and it stood out as a food supplier in the world in 2020. Farmers’ vocations and the integration of productive food chains led to a surplus of 1.2 billion dollars, with an annual increase of 39.92%. The pandemic is a challenge and an opportunity for the Mexican countryside in terms of digital and technological innovation derived from border investigation. However, it is crucial to establish public agricultural planning policies to help optimize this area of opportunity by focusing on new production and national and international trade models, responding efficiently to national visions to benefit  producers-consumers and guaranteeing food security in the framework of the UN’s international policies for sustainable development, the IPCC’s reduction of climate impact and ensuring human health by the WHO.

Authors: Raihing Pinky , Vijayalakshmi A.
Published: January 2022

Background: Composting is the process of breaking down of organic matter using living organisms which can be used as manure for soil conditioning. Vermicomposting is the rapid decomposition of biowastes using earthworm species which will enhance the growth and yield of plants. Methods: The vermicomposting of vegetable and fruit wastes was carried out during summer season (May-July) and by using the vermicompost a pot culture experiment was conducted in black gram for three months from August to October, 2019. The treatments consist of combinations of vermicomposted wastes and cowdung along with bioinoculants, Soil served as control. The biometric parameters such as root length, shoot length, fresh weight and dry weight on 15, 35, 55 DAS and yield characters like number of pods/plants, number of seeds/pods, pod length, weight of seed/pod, pod fresh weight and pod dry weight were recorded and statistically analysed. The present study has been attempted to convert the vegetables and fruit waste into compost as manure and analyse its effect on vegetative growth and yield parameters of Black gram (Vigna mungo L.). Result: The highest value of shoot length, root length, fresh weigh and dry weight were noted in fruit waste + cow dung + Pleurotus eous (APK1) + Trichoderma asperelloides + Eudrilus eugeniae on 15, 35 and 55 day after sowing (DAS) and the least was reported in control (only soil). The application of T8 treatment reported the highest yield characters which were followed by other treatments and control on 15, 35 and 55 DAS. The study concluded that T8 (F.W + cow dung + P. eous + T. asperelloides + Eudrilus eugeniae) is an effective biocompost for the growth and yield of black gram (Vigna mungo L.) which is eco-friendly.
L’ENSEIGNEMENT DU FRANÇAIS LANGUE ÉTRANGÈRE DANS UN CONTEXTE DE PANDÉMIE : ASPECTS TECHNOLOGIQUES ET CULTURELS
Authors: Manić-Matić Vanja
Published: January 2022

Depuis l’apparition du virus COVID-19 et de la crise sanitaire globale, nous vivons dans une nouvelle époque qui nous a imposé de nouvelles habitudes et de nouveaux comportements. La pandémie s’est reflétée dans tous les domaines de la vie, sur le plan de l’enseignement/apprentissage du français langue étrangère (FLE), aussi bien que sur le plan culturel. Les interactions entre les humains ont considérablement changé la manière de penser et de réagir. D’une part, dans l’enseignement/apprentissage du FLE en contexte universitaire aussi, la méthodologie et l’approche pédagogique ont dû être adaptées et sont, par conséquent, devenues virtuelles. D’autre part, les échanges culturels ont trouvé un nouveau biais pour se manifester et pour se développer. L’objectif de ce travail est d’attirer l’attention sur les importants changements liés à la pandémie et enfin développer les consciences autour de ces nouveaux enjeux en vue d’une amélioration et d’un approfondissement de l’enseignement/apprentissage du FLE. En se basant sur notre propre expérience et sur la méthodologie descriptive, nous en donnerons les résultats les plus importants de la recherche : des changements méthodologiques de l’enseignement/apprentissage du FLE en contexte universitaire, ainsi que des changements interculturels où les frontières s’effacent en pandémie.
LA LECTURE FRANÇAISE DE MILUTIN MILANKOVIĆ

Published: January 2022

Il y aurait eu peu de chance que les œuvres de Milutin Milanković, mathématicien, astronome et climatologue qui, pour les non-initiés, portent des titres énigmatiques et parlent des phénomènes thermiques et de la radiation solaire attirent l’attention des littéraires, si parmi elles on n’avait pas trouvé quelques œuvres de vulgarisation scientifique, destinées au grand public. L’une d’elles, intitulée Kroz vasionu i vekove (À travers l’univers et les siècles) de 1928, roman épistolaire de vulgarisation, dévoile assez rapidement la lecture française de l’auteur. L’influence de Bernard Le Bovier de Fontenelle et de son livre Entretiens sur la pluralité des mondes de 1686 paraît évidente. Ni les historiens des sciences, ni les historiens de la littérature n’en disent pas grand-chose. L’analyse comparative de ses deux ouvrages qui, utilisant des procédés semblables, explorent des zones frontalières entre la science et la fiction du XVIIe et du XXe siècle, fait l’objet de ce travail. Nos objectifs dans cet article étaient de replacer les ouvrages présentés dans le contexte scientifique et culturel de l’époque, puis de jeter un regard nouveau sur des textes littéraires à forte teneur scientifique, analyser le phénomène de vulgarisation scientifique et enfin de mettre en évidence les rapports souvent méconnus entre littérature et science.
L’ESPACE DANS LES PIÈCES HÔTEL DES DEUX MONDES D’ÉRIC-EMMANUEL SCHMITT ET HUIS CLOS DE JEAN-PAUL SARTRE
Authors: Bjelić Nikola , Cvetković Vanja
Published: January 2022

Dans notre article, nous nous proposons d’analyser le rôle de l’espace dans la pièce Hôtel des Deux Mondes (1999) d’Éric-Emmanuel Schmitt en la comparant avec la pièce Huis clos (1944) de Jean-Paul Sartre. La pièce sartrienne nous servira de repère et de point de départ à l’analyse de l’espace chez Schmitt vu les nombreuses relations intertextuelles qui les relient. Cette intertextualité est visible sur le plan du contenu ainsi que sur le plan des idées exposées : l’existence humaine et la mort, la condition humaine, Dieu, le mysticisme. L’espace y joue un rôle essentiel. Il s’agit d’un espace fermé, clos, mais actif : dans Huis clos c’est un salon style Second Empire qui représente l’enfer, dans Hôtel des Deux Mondes une clinique qui se trouve entre la vie et la mort. À partir de différentes classifications de l’espace théâtral d’Hélène Laliberté, nous chercherons à déterminer la fonction mimétique de l’espace, c’est-à-dire le rôle de l’espace figuratif dans le déroulement de l’action. Pour mieux comprendre le rôle que joue l’espace fermé dans les deux pièces, nous utiliserons dans notre analyse les recherches de l’espace théâtral d’Anne Ubersfeld, surtout les deux types d’espace : le lieu scénique, ce même espace scénique « en tant qu’il est matériellement défini » (Ubersfeld, 1996a : 37), et l’espace dramatique, une abstraction qui  « comprend non seulement les signes de la représentation, mais toute la spatialité virtuelle du texte, y compris ce qui est prévu comme hors scène » (Ubersfeld, 1996a : 37). Le but de notre article sera d’analyser ces deux types d’espace dans la pièce de Schmitt, leurs points communs et différences avec ceux de la pièce sartrienne.
DIONYSOS À NEW YORK : LES FRAGMENTS DU MYTHE DIONYSIAQUE DANS ONYSOS LE FURIEUX DE LAURENT GAUDÉ
Authors: Vlaškalić Nebojša
Published: January 2022

Onysos le furieux est le premier texte théâtral de l’écrivain contemporain français Laurent Gaudé. Écrit en 1997 et publié en 2000, ce monologue au souffle épique propose une nouvelle lecture du mythe dionysiaque. Assis sur le quai d’un métro new-yorkais, Onysos prend la parole et nous emmène dans un voyage à travers le temps et à travers son histoire, qui est, en réalité, celle de Dionysos – un peu moins dieu, un peu plus homme. Le dessein de l’écrivain n’est pas de réécrire ou d’adapter une des nombreuses variantes classiques du mythe de Dionysos, mais de tisser un nouvel espace mythologique, sa propre antiquité imaginaire, à partir de particules mythiques hétérogènes et amalgamées. En nous appuyant sur la mythocritique de Philippe Walter, nous analyserons dans ce travail les mythèmes, les plus petites unités de discours significatives sur le plan mythique, qui constituent le puzzle du mythe dans Onysos le furieux. Nous tâcherons de retracer les mythèmes empruntés aux différentes variantes classiques du mythe de Dionysos (la naissance tragique, le démembrement, la descente aux Enfers, l’épisode avec Proscumnos, Dionysos travesti, etc), ainsi que les mythèmes construits, auctoriaux.

This chapter examines interactions of dietary fibre components of pig diets with GIT microbiota, emphasizing cereals and legumes fed to pigs. Carbohydrate composition of these feedstuffs are described, and their relationship to metabolic activity of the porcine intestinal microbiota and interactions with the host. Fermentable carbohydrates which act as substrates for microbial metabolism are described, followed by an assessment of cereals and legumes as potential modulators of intestinal microbiota. Past work focussed on purified extracts, but attention is now focussing on whole grains or their fractions such as brans, in terms of effects on microbial populations. Such studies are showing the positive consequences of mixtures of DF in the form of complex plant cellular structures, rather than single refined ingredients, to achieve beneficial health outcomes. Further work is also needed to define appropriate quantities and types of DF to achieve desired effects whilst minimising negative outcomes.

Dietary and endogenous protein that become available for the microbiota in the hindgut can be metabolized via different routes. They can become building blocks for the microbial cells or enter different catabolic pathways. Protein degradation via fermentation pathways is seen as a non-preferred route as it results in the formation and release of metabolites that can interfere with biological systems in the host and can have deleterious outcomes. Reducing protein fermentation and guiding the metabolism towards less toxic end-products might be possible targets for improving host health. To do so, more knowledge on factors manipulating the process of microbial protein metabolism, including on substrate availability, microbial composition and segmental differences in the hindgut, is required.

This article explores moderate and eclectic traditionalism beyond Kiai Haji Muhammad Hashim Ash’ari’s contribution in the shariah and Islamic jurisprudence of social politic (Fiqh al-Siyâsah al-Ijtimâ’iyah) in Indonesia. It is conceptual research referring to some of his works as well as discussion about his thought among Islamic scholars. Based on definition of moderation from the Qur’an, hadith, and some scholars’ opinion, Hashim can be best categorized as Islamic traditionalist figure who enforced both moderation and eclecticism. However, he maintained distinctive features compared to both traditionalist and modernist Islamic figures. It is mainly clear from both his thought and movement which rely on the Ahlus Sunnah wal Jama’ah in theology, four fiqh school leaders (Hanafiyah, Malikiyah, Syafi’iyah dan Hambaliyah), and thariqah sufiyah mu’tabarah. Additionally, he showed appreciation and promoted for adaptation to both local and foreign idea that later inspired distinctive religiosity in Indonesia. This particularly applies in the concept of relation between Islamic law and nationalism, jihad, political fiqh and governmental system in Islam.

Se utilizaron cajas de poliuretano para la incubación artificial de nidos. Se obtuvo una eclosión promedio de crías del 75.2% (± 19.3). Para evitar la depredación de huevos es importante mantener la incubación artificial en cajas de poliuretano. Por la mayor incidencia de nidos en las playas Malecón (75.5 ± 12.4 nidos playa año) y Cerritos (51.3 ±26.5 nidos playa año), y por 11.5 y 8.3 nidos km−1, respectivamente, es necesario incrementar su vigilancia.

Para rehabilitar terrenos degradados en zonas áridas, es necesario superar limitaciones bióticas y abióticas con metodologías de bajo costo que permitan lograr reforestaciones exitosas. Este trabajo abordo cómo mejorar el crecimiento y supervivencia de plantas, y mitigar las condiciones de temperatura y herbivoría en la reforestación de terrenos degradados. Fueron construidos refugios protectores reutilizando desechos de poda y envases plásticos. Durante un año, 264 plantas de palo verde (Parkinsonia microphylla) fueron sometidas a tratamientos diferenciales de protección contra herbívoros (sin protección, y con protección por refugios de ramas, PET o ambos), y se monitoreó su supervivencia y altura. La supervivencia de plantas con el uso de refugios protectores fue mayor que la de las plantas sin protección (34.9-56.7 vs. 1.8%, χ2 = 63.5; p < 0.0001); asimismo, las alturas de las plantas protegidas fueron mayores. El uso de refugios es una alternativa efectiva, para la reforestación de terrenos degradados.

El estado de San Luis Potosí cuenta con ecosistemas boscosos que tienen limitada investigación en el ámbito forestal. Los estudios sobre la estructura y diversidad arbórea se realizan para generar información necesaria para efectuar un manejo conveniente en estos ecosistemas. El objetivo de la investigación fue evaluar y comparar la estructura y diversidad de especies forestales para dos condiciones de bosque templado bajo manejo forestal en San Luis Potosí. Se realizó un muestreo aleatorio para lo cual se establecieron tres parcelas de muestreo de 2 500 m2en cada localidad. Se obtuvo información dasométrica de individuos mayores de 7.5 cm de diámetro normal y se determinó la composición de especies, densidad por hectárea, abundancia, dominancia, frecuencia, índice de valor de importancia (IVI) e índice de distribución vertical (A). Para la UMA San Rafael se registraron 323 individuos, de cuatro familias, cuatro géneros y 10 especies; la abundancia fue de 430 árboles ha-1; siendo Pinus teocotela especie con mayor IVI (71.02%). En el Predio San Joaquín se registraron 277 individuos, que pertenecen a tres familias, tres géneros y ocho especies; la abundancia fue de 369 árboles ha-1; P. devonianafue la especie de mayor IVI (98.92%). La riqueza específica fue de 10 y 8 especies, con índice de Margalef de 1.55 y 1.24. En relación con la diversidad del área, el índice de Shannon (H’) tuvo un valor de 1.91 y 1.51, respectivamente. P. devoniana es la especie con mayor dominancia en ambas localidades con 4.04 y 6.62 m2ha-1.

El frijol caupí (Vigna unguiculata(L) Walp) es un cultivo importante en varias regiones del mundo, pero en México no es muy explotado. La caracterización de variedades agrícolas se ha basado en descriptores morfológicos, en los que se incluyen: forma, color y tamaño de semilla, además de atributos cuantitativos como el contenido mineral. El objetivo del trabajo fue evaluar las características morfológicas y nutricionales de genotipos de frijol caupí de la Península de Yucatán, México. Se realizaron 15 colectas de octubre 2017 a enero 2018, a las que se evaluaron tres variables morfológicas cualitativas, 10 variables cuantitativas y se determinó el contenido de potasio, calcio, manganeso, hierro y zinc, mediante μ-fluorescencia de rayos-X. A los datos se les realizó un análisis de varianza y de componentes principales. El 80% de las colectas tienen forma ovoide, 73% textura suave a áspera y el 80% son de color negro. En las variables morfológicas cuantitativas, 53% de las colectas se consideran pequeñas, 40% medianas y 7% semillas grandes. La longitud, ancho y espesor de los genotipos fue de 6.26 a 9.56, 3.64 a 7.48 y de 2.86 a 5.56 mm, respectivamente, la colecta PET15 fue la de menor dimensión. Para el contenido mineral, la colecta OXC04 tuvo la mayor concentración de Ca, Mn, Fe y Zn, mientras que la colecta PET07 presentó mayor contenido de K. Hay altos niveles de diversidad fenotípica en las colectas estudiadas y se agrupan con base en sus características físicas y no al lugar de origen.

El cultivo de chile, además del uso culinario posee actividad antimicrobiana, debido a la acción de antioxidantes. Por lo que es de interés en la producción agrícola, como alternativa en el manejo de enfermedades en plantas. El objetivo del estudio fue evaluar la capacidad antioxidante de cuatro variedades de chile y su efecto antifúngico contra Fusarium andiyaziy Cochliobollusspp., ambos son patógenos severos en el cultivo de espárrago y albahaca. A partir de muestras de frutos de chile habanero, jalapeño, serrano y morrón, se obtuvieron extractos etanólicos, donde se determinó su capacidad antioxidante. La acción antifúngica, se evaluó mediante dos técnicas; la prueba de zona de inhibición en PDA y la germinación de esporas en caldo de papa-dextrosa. La actividad de los extractos se evaluó mediante la medición del halo de inhibición, a los cinco días después de la siembra y la germinación de esporas a través de la cuantificación de las mismas a las 48 h. Los resultados indican que el extracto de chile habanero presentó mayor capacidad antioxidante (11.9 mg g-1) y porcentaje de inhibición contra F. andiyaziy Cochliobollusspp., (55.61 y 82.29%), al tener respuesta similar al fungicida. La acción de inhibición de los patógenos en el resto de los extractos, varió entre éstos independiente de su capacidad antioxidante, donde posiblemente actúen otros compuestos. El extracto de chile habanero es eficaz para controlar Cochliobollusspp. y Fusarium andiyazi, y puede ser una alternativa para el control de estos fitopatógenos en la agricultura orgánica.

Dormitator latifrons habita en un amplio intervalo de salinidades producto de su ciclo migratorio y reproductivo. Nuestro objetivo fue evaluar el tiempo de respuesta fisiológica y la sobrevivencia al cambio salino en condiciones de laboratorio. Se midió la frecuencia ventilatoria branquial basal de organismos que se encontraban en 33 ups (AS) y en agua dulce 0.3 ups (AD). Se contabilizo la frecuencia ventilatoria branquial de organismos que fueron transferidos AD-AS e inversamente AS-AD (15, 25, y 33 ups), por triplicado, durante 1 minuto, 1, 4, 24 y 48h. Se encontraron diferencias estadísticas (p<0.05) en los peces transferidos de AD-AS y AS-AD al primer minuto con respecto a FVB basal. En todos los tratamientos una hora después de ser expuesto al cambio salino regresaron a la FVB basal. Se registro un 100% de sobrevivencia en todos los tratamientos. D. latifrons presenta una rápida respuesta fisiológica a cambios bruscos de salinidad.

La mayoría de los suelos de la Mixteca Alta presentan altos niveles de degradación. Una estrategia para su manejo y conservación es a través de integrar el conocimiento local y el análisis espacial para delimitar zonas aptas para la producción de café. El objetivo fue evaluar la aptitud de las tierras para cultivar café en la Mixteca Alta, del estado de Oaxaca considerando el conocimiento local y sistemas de información geográfica. Se desarrolló un modelo de aptitud de tierras para el cultivo de café con base en el análisis de la altitud, la inclinación de la pendiente y el suelo. Los cafetales no aptos se localizan en las zonas con menor altitud, la cuales también fueron las más cálidas y con la mayor presencia de roya. También la altitud del terreno mayor a 2 200 msnm no es apta para el cultivo del café debido a la presencia de heladas. La inclinación de la pendiente del terreno mayor a 80o no es apta para el cultivo del café. Las tierras muy aptas ocupan solo 258.1 ha; las aptas 2 030.4 ha; las medianamente aptas 3 162.3 ha; marginalmente aptas ocupan 2 558.8 ha; y las no aptas 5 123.9 ha. Las tierras aptas para el cultivo del café tienen suelos profundos con texturas franco-arcillo-arenosas y un espesor de hojarasca promedio de 5 cm. Este trabajo puede servir de referencia para la evaluación de tierras en zonas con escases de información geográfica del medio físico.

La enfermedad del permanente del tomate o zebra chip cau- sada por “Candidatus Liberibacter solanacearum” (Ca. L. solanacearum), es de gran importancia en las regiones productoras de tomate en México, la cual causa pérdidas de entre el 60 y 100% de la producción. El objetivo del trabajo fue evaluar el efecto de seis fosfitos (FOS), ácido salicílico y acibenzolar s-metil sobre el crecimiento del cultivo de tomate y la severidad de Ca. L. solanacearum. Las plantas de tomate se infectaron con Ca. L. solanacearum mediante el confinamiento con adultos de B. cockerelli portadores de esta bacteria. Como respuesta se evaluaron la disminución de la severidad de la enfermedad y nueve parámetros agronómicos. La aspersión de fosfitos redujo la severidad de los síntomas de la enfermedad ocasionada por Ca. L. solanacearum, mejorando las variables altura de planta, peso del fruto, peso de planta y peso de raíz. En cambio, la aspersión de ácido salicílico y acibenzolar s-metil no redujeron los efectos de la enfermedad en el cultivo de tomate.
