Authors: Egbe N. E. , Ihediwa L. , Abdulsalami M. S. , Adebayo A.
Published: October 2022

This investigation was carried out to assess citric acid production by Aspergillus species isolated in some locations within Kaduna metropolis Nigeria using standard methods. Fungal isolates identified as Aspergillus niger were obtained from samples collected from four (4) different locations.  Isolates were subjected to substrate preference test using local substrates such as wheat straw, rice straw and potato peel powder. Wheat straw supported the highest growth value of 41%. Screening of A. niger isolates for the production of citric acid showed that the isolate from Kawo (Kw) gave the highest yield of citric acid (0.38g/100ml) on basal screening media. Optimization of pH and temperature were carried out and the optimum temperature and pH for citric acid production by isolate Kw was 30OC (0.65g/100ml) and pH 6.0. The wheat straw treated with 5 N HCl produced a high yield of citric acid with a value of 25.60g/kg while the untreated wheat straw produced a yield of 13.3g/kg. Molecular characterization to confirm the identity of the fungal isolates was carried out by the amplification and sequencing of the 5.8S gene of the ribosomal RNA and the two intergenic spacers ITS1 and ITS2 of the strains. By comparison (BLAST) of Aspergillus niger isolate to reference sequence in the gene bank, a sequence similarity of 99% to 100% of other Aspergillus niger strain was obtained. Various methods of strain improvement techniques could be adopted to increase citric acid production by the A. niger isolates obtained from this study.

Published: October 2022

The paper examined the ethnozoological study of wild bird species' body parts supply of eighty-three traditional medicine marketers in six traditional medicine markets in Abeokuta North and South Local Government Area, Ogun State, Nigeria using snowball and convenience sampling techniques through the administration of a set of structured questionnaire to 83respondents. The result showed that four-fifths of the total respondents were females (85.54%), two-thirds of the total respondents (68.68%) were less than 50 years and 91.56% of the total respondents had formal education. A total of 21 bird species had their body parts and products on sale in the different markets studied in the study area. Due to the belief and faith of the people, the respondents agreed that there were some bird species that are regarded as being sacred or forbidden and thus, the birds and their bird body parts are used and sold in traditional medicine to treat different ailments and for sacrificial activities of their clients. It was concluded that the existence of bird species cannot be over-emphasized because they are important in believed resources for curing specified types of ailments and sacrificial offerings in traditional medicine. It was recommended that since birds significantly contribute to the natural ecosystem, human health and nutrition, forest and wildlife conservation campaign should be strengthened.

Published: October 2022

Uapaca ambanjensis Leandri (Phyllanthaceae) is a largely un-researched plant whose crushed stem bark, leaf, and fruit infusions are ethno-medicinally claimed to cure typhoid fever, other fevers, skin diseases, and stroke. This work aimed at the isolation, characterization, and determination of antimicrobial potency of the methanol stem-bark extracts of Uapaca ambanjensis.  Phytochemical screening revealed the presence of alkaloids, glycosides, flavonoids, tannins, saponins, steroids and triterpenes in the methanol extract. The antimicrobial assessment of the extract against Salmonella typhi, Staphylococcus aureus, Streptococcus pyogenes, Klebisiela pneumoniae, Pseudomonas aeruginosa, Candida albicans, and Aspergillus niger showed the diameter of zones of inhibition (ZOI) ranging from 11 to 18 mm at a concentration of 12.5mg/mL to 100mg/mL, with most prominent activities against S. aureus, S. typhi and P. aeruginosa. Chromatographic fractionation and purification led to the isolation of a pentacyclic triterpenoid (friedelan-3-one) labeled G23f-9. The compound showed antimicrobial potency evidenced by zones of inhibition against S. aureus (20 mm), S. typhi (16 mm), S. pyogenes (14 mm), K. pneumoniae (13 mm), and P. aeruginosa (13 mm) at a concentration of 100 µg/mL while the values for the standard drug, Ciprofloxacin, at 10 µg/mL are respectively 24 mm, 20 mm, 27 mm`1,20mm and 18mm. The Minimum Inhibitory Concentrations (MIC) were 12.5 µg/mL for S. aureus, 25 µg/mL for S. typhi and 100 µg/mL for the rest while the Minimum Bactericidal Concentrations (MBC) were 50 µg/mL for S. aureus and 100 µg/mL for S. typhi. The isolated compound showed some antifungal activity against C. albicans with ZOI of 11 mm at 100µg/mL while the antifungal drug, Terbinafine, gave 30 mm at 30 µg/mL. Phytochemical and antimicrobial results lay credence to some ethnomedicinal claims on the plant including its use to treat typhoid fever and some skin diseases. The biological assessment of the methanol extract and isolated compound reveals that the plant could have antibacterial and antifungal potentials. The isolation of Friedelan-3-one is reported for the first time from the plant U. ambanjensis Leandri.

This study determined the concentration of trace metals in vegetables (lettuce, tomato and cabbage) from Gombe markets, Gombe State, Nigeria. A total of 60 samples of vegetables were analyzed for trace metals (Cd, Pb, Mn, Cr, Zn, Ni and Cu) using Atomic Absorption Spectrophotometer (AAS). The mean concentration of Cd in lettuce, tomato and cabbage samples ranged from (0.05 - 0.06 mg/kg), (0.03 - 0.07 mg/kg) and (0.08 - 0.90 mg/kg),  Pb ranged from (BDL - 0.02 mg/kg), (BDL - 0.03 mg/kg) and (0.01 - 0.02 mg/kg), Mn ranged from (0.27 - 1.02 mg/kg), (0.09 - 0.12 mg/kg) and (0.25 - 0.31 mg/kg), Cr ranged from (0.05 - 0.65 mg/kg), (0.04 - 0.05 mg/kg) and (0.03 - 0.05 mg/kg), Zn ranged from (2.67 - 3.32 mg/kg), (1.93 - 2.87 mg/kg) and (2.45 - 3.26 mg/kg), Ni ranged from (0.68 - 0.77 mg/kg), (0.23 - 0.26 mg/kg) and (0.73 - 0.86 mg/kg), and Cu ranged from (0.95 - 0.97 mg/kg), (0.76 - 0.83 mg/kg) and (0.94 - 1.00 mg/kg) respectively.  The abundance of trace metals was found in decreasing order: Zn > Cu > Ni > Mn > Cr > Cd > Pb in lettuce, tomato and cabbage samples. The concentration of trace metals in the different vegetables were below the World Health Organization/Food and Agriculture Organization (WHO/ FAO) standard, except Cd in all studied samples. Therefore, monitoring and strict regulation is recommended to control the safety of vegetables sold in these markets.
Effect of the Richardson Number on Flow and Heat Transfer in a Cylinder Filled with Cu-Water Nano-fluid at Different Nanoparticle Concentrations
Authors: Sangotayo E. O. , Ogidiga J. O.
Published: October 2022

Fluid circulation and thermal exchange properties via integrated natural and artificial convection within a container have attracted considerable interest due to its many industrial uses. This present work concentrates on determining the effect of the Richardson number on flow and heat transfer in a cylinder filled with Cu-Water nanofluid at different nanoparticle concentrations. The governing equations: continuity and Navier Stoke fields were discretized using the finite difference approach and simulated in C++ programming language. In this work, the Richardson parameter ranged from 2.6*104 to 2.8*104, while the concentration of Cu nanoparticles ranged from 1% to 10%, and the results are presented as Nusselt number, vorticity, and stream function profiles. The results reveal that the maximum Richardson value is 2.76 x 104 at the nanoparticle volume of 0.04, resulting in a considerable increase in the convective heat transfer rate. Furthermore, as the Richardson parameters increase, the Nusselt number in the nanofluid increases exponentially while the local drag coefficient decreases. The stream function, longitudinal velocity and circulation increase as the Richardson parameters grow. The technical design for air turbulence prediction involves an understanding of the Richardson-driven connection as a mix of wind speed and convective stability variables.

Published: October 2022

The growth of air traffic all over the world faces an increasing risk of aircraft collisions with birds. The Black Vulture (Coragyps atratus), being a large soaring species living across the Americas, presents a serious hazard to airplanes. The reduction of this threat without harm to birds is a complex task requiring thorough investigations of their behaviour. Various natural and anthropogenic factors can affect the distribution of soaring Black Vultures in the surrounds of airports. Here we focus on the impact of meteorological parameters (i.e. air temperature, relative humidity, wind speed and atmospheric pressure) on Black Vulture flight at two study sites. In the course of one year, from September 2012 to August 2013, we surveyed with binoculars the soaring activity of Black Vultures around Amarais and Presidente Prudente airports in the southeast of Brazil. The study areas were characterized by tropical climatic conditions with mild dry winter and hot rainy summer. We found that the frequency of soaring flights depended on the wind speed, a proxy of the strength of thermals (upward air flows). This finding is consistent with habits of Black Vultures using thermals for soaring. In contrast, air temperature, air humidity and atmospheric pressure did not affect their activity. We also showed that the different seasons affected the birds’ behaviour, but the degree of their influence depended on the level of anthropogenic pressure in the soaring terrain. Two contrasting types of daily soaring activity appeared: a plateau-like trend and a tendency of two peaks at morning and afternoon with a pronounced drop between them. Our findings can be used to inform methods to reduce the risk of collisions between aircraft and Black Vultures at our study sites, and our analytical approach could be applied elsewhere.

Vital Medications in the World According to Preliminary BCS Classification: Prognostication of Solubility and Permeability
Authors: Dudhat Kiran Rameshbhai
Published: October 2022

The Biopharmaceutical Classification System (BCS) has been used as a predictive method to evaluate potential formulation impacts on oral medication bioavailability in humans. The BCS can assist in the prediction of in vivo product performance and the construction of mechanistic models that enable formulation assessments through the generation of scenarios when used in conjunction with in vitro dissolution testing. The applicability of current human BCS standards has not yet been examined in dogs, which restricts its application in canine medication development. The BCS has had a significant impact on drug discovery, development, and regulation on a global scale and the BCS continues to receive much validation, discussion, and extension in the literature. Drug regulatory organizations from all across the world have fully deployed the BCS when establishing bioavailability/bio-equivalence requirements for the approval of oral drugs with instant release (IR). In this study, we examine the provisional BCS classification of the most popular medications sold worldwide and discuss the BCS scientific framework and its influence on regulatory exercise of oral medicinal products. Also mentioned is the Biopharmaceutical Drug Disposition Classification System and how it relates to the BCS.

Published: October 2022

Twitter and other social media platforms have emerged as popular channels for communication during emergencies. Social networks generate huge amounts of data due to the behaviour of their users. A wide range of topics is discussed on social networks, including politics, health issues, and natural disasters. Therefore, public data provides a wealth of information on many topics. Traditional methods of communication have been enhanced in many ways by the Internet. In disaster assessment, Machine Learning (ML) and Artificial Intelligence (AI) algorithms are becoming increasingly popular. The use of micro blogging platforms such as Twitter during natural catastrophes and emergencies generates an increasing number of posts on these platforms. In this paper, we examine natural disasters, including avalanches, tornadoes, hurricanes, droughts, earthquakes, landslides, tsunamis, floods, volcanoes, and wildfires. We extract data from Twitter Network and classify them as disaster and non-disaster tweets as target and non-targets using SVM, Word2Vec, TFIDF, and BERT model.

This research is motivated by the existence of obstacles that occur in the online learning process. Obstacles that occur can lead to not achieving the competencies that must be possessed by students. The purpose of this study is to describe the teacher's perception of online learning, the implementation of online learning, the obstacles to online learning, and the inhibiting factors of online learning. This study uses a qualitative approach with a descriptive method. Data collection techniques used are observation, interviews, and documentation. Meanwhile, the data analysis techniques used are data reduction, data presentation, and drawing conclusions based on Miles and Huberman. The results show that teachers think online learning is the right strategy to use during the Covid-19 pandemic. The implementation is only in the form of assignments via whatsapp groups. The obstacles include decreased student enthusiasm for learning, students' difficulties in understanding learning material, and the lack of maximum learning provided. The inhibiting factor for online learning is in the learning device such as cellphone.
MAGNETOELECTRIC VALVE MOTORS WITH TOOTHED MULTI-POLE WINDINGS BASED ON 6DVM 300
Authors: Afanasyev Aleksandr A.
Published: October 2022

The paper considers valve motors with toothed windings with pole numbers 2, 4, 6, 8, the main dimensions of which correspond to the 6DVM 300 valve motor manufactured by JSC “Cheboksary electrical apparatus plant”. This approach allows us to evaluate the effect of the number of stator teeth on the electromagnetic moment and its harmonic composition. The three adjacent coils of the toothed windings in question belong to three different phases. The paper analyzes the MMF of the windings and magnets of the rotor. The distribution of magnetic induction in the gap, the EMF of the stator winding and the electromagnetic moment are found based on the method of the specific magnetic conductivity of the gap. It is shown that the MMF curve of the stator winding consists of two multipolar rectangles of unequal height and width. Due to the non-sinusoidal distribution of magnetic field sources and the jagged inhomogeneity of the air gap, the curves of the phase EMF of the stator winding are also significantly non-sinusoidal. It is found that with an increase in the number of poles (from 2 to 8 poles) of the stator winding, the maximum induction in the air gap decreases from level 1 to 0.75 Tl, the average value of the electromagnetic moment increases from 120 to 160 Nm, the amplitude of the phase EMF remains unchanged, and the maximum (height of the rectangle) of the MMF of the stator winding is reduced from 2000 to 500 A.

Published: October 2022

Associated grass-legume pastures have advantages over grass monoculture; in order to evaluate them the association of black oat (Avena strigosa Schreb) with winter vetch (Vicia villosa Roth) was analysed. The objective of the study was to evaluate forage yield, the botanical, morphological, and chemical composition of black oat in monoculture and in association with winter vetch, at different crop heights and residual stubble heights. Eighteen treatments were evaluated in randomized complete blocks with divided plots. In large plots, the culture type (monoculture or association); and in small plots, nine harvest management options (combinations) of three crop heights (Ch: 40, 50 and 60 cm) and three residual stubble heights (Rsh: 8, 14 and 20 cm). Forage yield was higher (p ≤ 0.05) in Ch50-Rsh8, Ch60-Rsh8 and Ch60-Rsh14 during the second crop cycle, with an average 8555 kg DM ha-1. In monoculture and in association, more cuts were made (three to four) with Ch40-Rsh14 and Ch40-Rsh20 and fewer cuts (one to two) with Ch60-Rsh8, Ch60-Rsh14 and Ch60-Rsh20. Crude protein concentration was 19 % higher (p ≤ 0.05) in monoculture than in association (19.2 and 16.2 %); the highest concentrations (p ≤ 0.05) of crude protein were obtained in Ch40-Rsh8, Ch40-Rsh14 and Ch40-Rsh20 (average 20.5 %), and the lowest was recorded in Ch60-Rsh8 (13.2 %). The forage with the least neutral detergent fibre (p ≤ 0.05) was harvested in Ch40-Rsh8, Ch40-Rsh14 and Ch50-Rsh14 (average 43.4 %), and the highest (49.3 %) was obtained in Ch60-Rsh20. In monoculture and in association, a greater amount of forage was harvested, distributed in at least two harvests, with Ch of 50 and 60 cm in combination with 8 and 14 cm of Rsh. However, the forage did not have the best composition, due to higher concentrations of neutral detergent fibre and lower crude protein concentration.

MICROFINANCE AND GENDER DISCRIMINATION IN CREDIT ALLOCATION: AN ECONOMIC ANALYSIS OF INCENTIVE CONTRACTS
Authors: RATSIMALAHELO Zaka , FOUNANOU Mathurin , HOUNWANOU Didier
Published: October 2022

In this paper, we develop a model of discrimination by effort between women and men in credit markets. The specificity of our model compared to the current literature consists in the level of effort effected by the agents who benefited of a microcredit is endogenous. We assume that borrowers have financial constraints and that they want to obtain funds to carry out their projects whose success depends on costly and unobservable efforts. Assuming that women exert a higher level of effort than men, we show that when information is perfect, all projects are financed and the collateral is completely eliminated. Women benefit of a lower interest rate than men and at the same time receives a loan of the same amount as men. In a situation of imperfect information, when the level of the project manager’s effort is private information, we show that in a competitive credit market where risks are not mixed, the riskier borrower obtains the same contract as in a perfect situation. When the state can guarantee highrisk borrowers (low efforts), their welfare improves. On the other hand, when government can provide guarantees for lowrisk borrowers (high efforts), it reduces collective welfare.
Litter size and reproductive condition of small mammals in southern Goiás, Brazil
Authors: Parreira Claro Hermes Willyan , Hannibal Wellington
Published: October 2022

Litter size and reproductive conditions are important in natural history. However, this information is scarce in scientific literature. Here, we presented litter size data for eight small mammal species (four marsupials and four rodents) and investigated the reproductive conditions of three small rodent species in the transition between the Atlantic Forest and Cerrado in central Brazil. We counted the number of young born, the number of embryos found in the uterus, and recorded the presence of well-developed teats and evident scrotum to evaluate the reproductive condition. The litter sizes ranged from one (Oecomys bicolor) to 11 (Gracilinanus agilis and Marmosa murina). We did not find evidence of reproductive seasonality. The pattern found here is similar to other studies carried out in different locations of South America.

Published: October 2022

Regional development through the tourism sector is not only related to the provision of employment and regional investment. However, it is also related to the availability of public facilities. Good management of public facilities and friendly to children and the environment is directly a part of tourism development. This study uses a qualitative approach in an effort to explain the availability of public facilities in open spaces to support tourism programs in Manado City. Research findings that public open spaces in Manado City have not met the needs in terms of the amount of space and functions and facilities that have not taken into account social, economic, environmental, and educational aspects. The management of very limited facilities has resulted in public open space that should be used as a medium for promoting tourism objects in supporting tourism programs through the smart city concept.

Synovial haemangioma is a rare clinical condition which refers to abnormal proliferation of blood vessels in the synovia membrane of a joint. This usually arises in tendon sheaths, synovial membranes of joints or bursae. The lesion is a benign vascular neoplasia was first described by Bouchut in 1856 that occur most frequently around the knee. Trauma has been reported as an Aetiological factor in the formation of post traumatic synovial haemangioma in young adults. The granulation tissues formed following minor trauma to muscle and joint may cause proliferation and infiltration endothelial tissues and subsequently enlarges and grows into vascular tumours. Post traumatic Synovial haemangioma of the elbow usually mimics other lesions as bursitis. This case was an incidental finding of synovial haemangioma of the elbow following trauma in a young adult.
The blood brain barrier and Lina Solomonovna Stern (Shtern)
Authors:   Hull Royal Infirmary, Hull, UK, Pearce JMS
Published: October 2022

The blood–brain barrier (BBB) regulates the transport of molecules between the central nervous system (CNS) and blood. It consists of two components: the vascular endothelial cells forming so–called tight junctions, and the blood–cerebrospinal fluid barrier. It plays an important role in the pathogenesis and in recovery from many cerebrospinal disorders. Paul Ehrlich was the first to observe in mice that intravenously injected acidic dyes stained the tissues of the body but not the brain. He deduced there was a barrier between systemic blood and nervous tissues. His pupil Lewandowsky visualised a capillary wall that blocked the entrance of certain molecules. And, Edwin Goldman injected trypan blue into the CSF and observed that the brain but no peripheral organs was stained — indicating the dye could not cross from CSF to the systemic bloodstream, but could leave the blood vessels of the choroid plexuses within the ventricles to enter the brain tissues. Experiments of the heroic Russian Lina Solomonova Stern (Shtern), persecuted by Stalin, formulated the rule that every substance contained in the blood must penetrate the cerebrospinal fluid before it can exercise its effects on the nerve elements; she named the blood–brain barrier: barrière hémato–encéphalique.

Published: October 2022

Four samples of the compound (Bi₂Ba₂Ca₂Cu₃O₁₀₊δ) were prepared by solid-state reaction method, using annealing method, at a temperature of 800 ℃ and under hydraulic pressure of 8 tan/cm² by partial substitution of the nanoparticle lead by 0.5 from bismuth, strontium and titanium nanoparticles at a ratio of (0.1,0.3,0.5) of the element barium Ba of the compound. Electrical tests showed an increase in the value of the critical temperature Tc when compensation the material with a value of X = 0.5 for the Pb nanoparticle values of Bi and y = 0.1 compensation for the values of Sr,Ti, and from the element Ba, where the critical temperature Tc reached a value of 144.5 k and When compensation the substance with a value of x = 0.5 for the values of pb nanoparticle from the element Bi and y = 0.3 for the values of Sr,Ti from the element Ba, the highest increase in the value of the critical temperature Tc was 152.2 k, but it decreased when compensation the substance with x = 0.5 for the values of the Pb nanoparticle From the Bi element and y = 0.5 compensation for the values of Sr,Ti, from the Ba element to k 145.5. The structural properties of the X-ray diffraction of the models showed the presence of a certain phase in the three values with varying differences in the dimensions of the network a, b, c with a clear increase in the dimension c. When examining the samples with a fesem device with a magnification rate of 500kx ---100.00kx, it was found that the average particle size of the best samples was 38.28 nm at the sample X=0.5 and y=0.5. The images of the four models show very high-resolution images and are very detailed, and it appears that light structures belong to the light elements and dark areas belong to the heavy elements. The study under consideration showed the magnetic properties through the hysteresis curve of the samples and the relationship between the saturation magnetism Ms and the remanence magnetization Mr and the coercive force Hc that the hysteresis rings formed in the superconducting samples are narrow and there is an inverse relationship between the tightness of the rings and the improvement of the critical temperature Tc.

A person obtaining the nationality of a particular country is the criterion for distinguishing between the original national or the emergency national and the foreigner. The rights and conditions of individuals in society and the extent of submission to the state’s law or not are determined. And the foundation and launch of the legal authorities build on the foundation stone laid by the foundation stone of the concepts, concepts and principles adopted by the legislator, the national legislator, seeing the goals of political and social goals, the constituents of the society he rules, its tribes, and its adoption. A nationality law is one of the national legislation that is considered a national legal, political and social association that expresses a person's relationship with a particular state. Attempting to achieve gender equality is one of the important goals that states seek in all areas of life to which a person is associated. From a legal point of view, national and international legislation seeks to supplement and strengthen the role and rights of the Iraqi family with legislation that contributes to reducing the differences between women and men and achieving A degree of real equality between the two, especially in matters of modern nationality, which led to a trend in law to achieve the principle of equality in granting nationality, whether through the mother as a woman in the first place or through the father and not to distinguish between the two. However, we find that this equality has not been achieved in many aspects.

THE CRIME OF HUMAN TRAFFICKING IN LIGHT OF THE PROVISIONS OF ISLAMIC SHARIA AND INTERNATIONAL CONVENTIONS - A COMPARATIVE STUDY
Authors: HURAISH Ammar Hamad , ALI Senaa
Published: October 2022

Praise be to God, Lord of the Worlds, and prayers and peace be upon the most honorable of the prophets and messengers, our master Muhammad and all his family and companions, and after: The crime of human trafficking in light of the provisions of Islamic Sharia and international conventions (a comparative study) given the seriousness of this heinous crime. As it is one of the serious and heinous crimes that have been forbidden by the heavenly religions and combated by international conventions, and texts and rules have been laid down for them that prohibit them and punish those who violate them. The evil one, which enjoys satanic inflections, has made this human element a commodity that is sold and bought to satisfy their sick souls and their sick satanic instincts in a terrible trade in which they are anxious to bring money. Undoubtedly, the relationship has become a direct relationship between a victim who falls into the clutches of a beneficiary, and this beneficiary wants to exploit it to the fullest extent. Without pity or mercy. The real challenge to these groups has begun in all parts of the world in its various categories, through the development of international agreements to ban, prevent and protect the world from these crimes, and issues that do not prevent these crimes, and the countries - for their part - have issued laws criminalizing human trafficking, and crimes are affected - usually - natural, geographical and economic factors. In this study, I dealt with the crime of human trafficking between Islamic Sharia and international conventions, and the crime of human trafficking is one of the crimes that haunt the contemporary world. Because of its violation of human rights, and Islamic law did not neglect to explain the provisions of this emerging and contemporary crime, as it proved beyond any doubt that Islamic Sharia is valid for every time and place, so it prohibited it in its many forms; Proceeding from the principle of God Almighty’s honoring of human beings, and ways of treatment have been developed for them through two aspects: preventive, through the establishment of educational procedures that distance the crime from society, and that committing it is a disobedience to God Almighty’s command, and my punishment through the penalties I set to combat this crime, which may reach in some Images to the penalty of limitation, or reprimand. The crimes of human trafficking are also considered one of the most dangerous criminal phenomena on humanity because of the affront to human dignity and its transformation into a cheap commodity, in addition to the wide spread of this crime and its link to organized crime and gangs. And through this study, we tried to identify the conceptual framework of the crime of human trafficking, in terms of its definition and statement of its forms, as well as the legal structure of this crime, based on what was stated in international conventions.‎

Em edições anteriores, falei sobre o unpacking de binários comprimidos por packers - os compressores de executáveis. Na edição número 15, mostrei como vencer a técnica anti-engenharia reversa de redirecionamento de IAT (Import Address Table). Antes de cobrir cenários mais avançados, vou explorar um pouco mais a reconstrução da IAT, a fim de te dar a oportunidade de fundamentar bases mais sólidas que serão muito úteis em desafios mais complexos de unpacking.
Lecturas y relecturas sobre el territorio. Una interpretación histórica.
Authors: Girbal-Blacha Noemí , Cerdá Juan
Published: October 2022

Este trabajo aborda el concepto de territorio, sus posibles interpretaciones y cómo fue utilizado por la historiografía regional argentina en la última mitad del siglo XX, así como su redefinición constante. En los últimos años, se fueron definiendo más claramente los límites de los conceptos de región, territorio y espacio pero persisten las dificultades para determinar los niveles de análisis y sus articulaciones con las particularidades económicas, sociales y culturales que se producen en cada una de las regiones. Por otro lado, este mayor nivel de precisión de los conceptos ha resultado en una pérdida de la dimensión del ambiente natural, que aleja al hombre del medio en el cual se desarrolla. Entendemos entonces que, la historia regional necesita un abordaje que tenga en cuenta dichos cambios teóricos y metodológicos –con el mayor nivel de complejidad posible- poniendo el acento en el estudio de casos particulares, que enriquezcan el análisis micro para explicar los procesos macro del heterogéneo y complejo mundo de los territorios

Industrialization and landscape: gum resin pinewoods of France, Spain and United States in the 19th and 20th centuries
Authors: Delgado Juan
Published: October 2022

Gum resin as natural resource has a long history. In regard to landscape transformation has been quite decisive in numerous pinewoods, however, it is barely known outside places of production and consumption. In the last two centuries the demand of its main by-products, spirit of turpentine and rosin, grew exponentially while chemical industries such as paint and varnish, paper, rubber, soap, etcetera, were increasing its production. Considering that was necessary to keep the forest standing in order to get the gum resin I am going to compare the situation of pinewoods in France, Spain and United States, to show the consequences in the landscape of this industrial activity in different contexts and backgrounds. The most important cause in pinewoods transformation into «organic machines» was forestry, and politics; nevertheless, its application depended upon regional and national trajectories. The case of gum resin pinewoods is a good example of how industrialization had to deal with nature to obtain organic chemical products, studying intensely the mechanisms of the forest and the pine with the economical and ecological idea that preserve them was the aim, and so, transforming them into a crop of pines with its socio-environmental consequences.
El uso de los montes vecinales en mano común gallegos. El antes y después de su devolución a las comunidades vecinales.
Authors: Freire Cedeira Araceli
Published: October 2022

Los montes vecinales en mano común gallegos, que habían sido intervenidos por el Patrimonio Forestal del Estado durante el franquismo para la producción forestal, fueron devueltos a las comunidades tras la Ley de Montes de 1968. En el momento de su devolución muchos continuaron con un uso forestal pero en otros, se ha producido una transformación completa del mismo. El objetivo de este trabajo es realizar un análisis comparativo de varios casos que siguieron caminos diferentes en el aprovechamiento del espacio tras su devolución. Pretendemos analizar tanto las causas como los efectos del conjunto de transformaciones económicas, sociales y de relación con el medio ambiente que se han producido en cada uno de los lugares de ubicación de los espacios analizados.
Discurso y política forestal en el peronismo histórico. Entre la protección al ambiente y el productivismo, 1946-1955
Authors: Carreras Doallo Ximena
Published: October 2022

En el presente trabajo se analiza la utilización y el manejo discursivo sobre la cuestión forestal en tanto recurso por parte del gobierno peronista (1946 - 1955). Esta temática se materializó a través de políticas ligadas a la legislación y los planes de acción del gobierno. Aunque también emerge en los medios de comunicación. La Chacra es una publicación mensual comercial de divulgación, de tirada nacional que se centró en el agro argentino.
En la extensión territorial argentina, lo forestal es relevante para la economía nacional por el perfil productivo que desarrolla la nación. Se plantea este trabajo entonces desde perspectivas de la historia ambiental y el estudio de fuentes para registrar cambios y continuidades en el discurso y su co-relato en la gestión política peronista.
Así, se observará y analizará la interrelación entre el recurso, su representación en las áreas gubernamentales, legislativas, sociales en tanto y cuanto impactan en el ciudadano y en el territorio. Se parte de la idea de nación conformada por leyes, cultura y Estado junto los ciudadanos y territorio. En este marco, las ideas acerca de la naturaleza son claves en los procesos históricos y en su interpretación.
Interpretación geográfica vidaliana de la Argentina de comienzos del siglo XX. La valorización del territorio según Pierre Denis.
Authors: Carballo Cristina
Published: October 2022

La Geografía vidaliana, o conocida también como la geografía regional francesa, tuvo un papel central en la producción del conocimiento geográfico para la compresión del mundo de fines del siglo XIX y comienzos del siglo XX. En ese contexto espacio-temporal la disciplina adquirirá un rol central para la consolidación del Estado Moderno en pleno auge del capitalismo industrial y financiero que no reconocerá fronteras. Esta expansión generará una configuración espacial periférica en el que se introducirá al territorio rural de Argentina a los ritmos del modelo agroexportador. El presente trabajo tiene como propósito plantear la construcción del espacio rural argentino y su imagen durante el auge la Argentina moderna. Para ello se propone: en primer término, reconstruir un marco interpretativo de la ciencia y el papel de los viajeros y de las exploraciones territoriales. Luego, analizar desde la geografía vidaliana los principales aportes que nos dejó la Geographie Universelle, desde la forma de concebir y reconstruir el continente americano como una realidad legitimada por la ciencia. Y por último, revisar la escritura como lectura de la Argentina de 1920 realizado por Pierre Denis, geógrafo francés que pondrá el acento en las contradicciones socio-espaciales que expresará territorialmente el heterogéneo mundo rural.
