New Approach to Identify the Most Sustainable Supplier Based on IFS
Authors:   National School of Applied Science, University Ibn Tofail, Kenitra, Morocco, Mariouli Oussama El , Abouabdellah Abdellah
Published: February 2022

To meet the expectations of consumers, who are increasingly demanding products that respect the concept of sustainable development (SD), companies are called upon to engage in an SD approach that begins with the selection of suppliers, taking into consideration the environmental, social and economic criteria. In this paper, we present a new model of selecting the best sustainable supplier. We have developed a hybrid model, which is built by extending the fuzzy set (FS) to the intuitionistic fuzzy set theory (IFS) and with the Decision Making Trial and Evaluation Laboratory (DEMATEL) method. Our model presented, allows us to measure the weight of the selected criteria of SD, to present an approach for defining the SD strategy within companies and finally to choose among the suppliers, the best supplier who respects the concept of SD by taking into consideration the links between the axe of SD. The results of the application of our approach have shown that our model can be easily used in all companies wishing to select sustainable suppliers. Keywords—Sustainable supplier selection; sustainable development; criteria; DEMATEL; intuitionistic fuzzy set; supply chain management.

— Network on chip (NoC) is a new method of interconnecting modules in system on chip (SoC). Now a day, it is believed that this new communication subsystem will replace the bus-based architecture and will become dominant in SoC design technology. The performance of NoC mainly depends on the router so it is considered as the crucial part in the NoC design. This paper describes the different factors which affect the NoC performance and provides solution to solve these problems. The proposed router has three architectural modifications which makes it dynamic and efficient as compare to generic virtual channel router. This paper introduced the dynamic buffer allocation scheme in which virtual channels and buffer slots are selected and allocated dynamically depending on the network traffic conditions in real time which in turn increases the throughput. In this paper, we have focused on optimizing the virtual channel arbitration (VA) unit design and switch allocation (SA) unit design as well as focusing the maximum utilization of buffer so that it will result in minimizing the latency, area and power. The source code of the router is written in VHDL hardware description language and the simulation and synthesizing the router is done in Xilinx ISE Design Suite 13.1. The parameters like area, frequency, delay, power, latency and throughput are calculated. The results of this modified virtual channel router are compared with the generic virtual channel router.

Crinóides da borda leste da bacia do Parnaíba (Formação Cabeças, Devoniano Médio)
Authors: Scheffler Sandro Marcelo , Silva Cleber Fernandes da , Fernandes Antonio Carlos Sequeira , Da Fonseca Vera Maria Medina
Published: February 2022

Este trabalho apresenta a descrição dos crinóides encontrados até o momento na Formação Cabeças (Givetiano da bacia do Parnaíba), coletados no afloramento km 305, no município de Picos, estado do Piauí. O material é constituído de colunais isoladas, dispostas esparsamente em amostras de arenito fino. Apesar dos espécimes não se encontrarem bem preservados, foram descritos três morfotipos (PB/Cb-01, PB/Cb-02 e PB/Cb-03). Dois deles (PB/Cb-01 e PB/Cb-02) estão representados apenas por um exemplar; o terceiro morfotipo (PB/Cb-03) é o mais comumente encontrado e, provavelmente, representa o crinóide mais abundante nos antigos ambientes de sedimentação do afloramento. A forma de ocorrência dos crinóides (provavelmente parautóctones) sugere a sua permanência, após a morte, na interface água-sedimento por tempo razoável antes do soterramento. Este fato é mais uma indicação a favor do modelo de um ambiente de barra de embocadura de sistema flúvio-deltaico influenciado por inundações, sugerido para a Formação Cabeças nessa região.
Distribuição espacial de vermetídeos (Mollusca: Gastropoda) no Atol das Rocas, Atlântico Sul equatorial
Authors: Soares Marcelo de Oliveira , Meirelles Carlos Augusto Oliveira de , Lemos Valesca Brasil
Published: February 2022

O Atol das Rocas é um recife biogênico localizado a 266 km do litoral do nordeste brasileiro. Sua estrutura carbonática é constituída por corais, algas calcárias, vermetídeos e foraminíferos. As espécies de vermetídeos analisadas são indicadoras do nível do mar e de paleoambiente intermaré ou imediamente submaré, o que as torna aptas a auxiliar na elucidação da história geológica do único atol do Atlântico Sul. Apesar da sua importância como bioconstrutores, existem poucos estudos enfocando a sistemática e a distribuição destes moluscos neste recife oceânico. Foram obtidos dados sobre as espécies, além da densidade e distribuição da tafocenose incrustante nos setores a barlavento e sotavento. As espécies Dendropoma irregulare (d’Orbigny, 1842) e Petaloconchus varians (d’Orbigny, 1841) foram reconhecidas em diferentes setores do sistema recifal, principalmente no setor a barlavento (0,26 ± 0,04 ind/cm2 century). Nos sistemas deposicionais com forte impacto de ondas, existe menor densidade de bioacumulação das conchas fossilizadas desses organismos (0,11 ± 0,02 ind/cm2 century).

Published: February 2022

This paper describes the avifauna sampled at Reserva Extrativista Chico Mendes, Acre, Brazil, during October and November, 2008. We recorded 344 bird species of 17 orders and 57 families through point counts, mist-nets and general observations. The most prevalent families were Tyrannidae, Thamnophilidae and Thraupidae with 53, 36 and 22 species, respectively. We recorded some range restricted, little know, and habitat specialists birds exemplified by Crypturellus atrocapillus, C. strigulosus, Primolius couloni, Aulacorhynchus prasinus, Drymophila devillei, Simoxenops ucayalae, Cnipodectes superrufus, Hemitriccus flammulatus, Percnostola lophotes, Xiphorhynchus chunchotambo, and Conioptilon mcilhennyi. Although we surveyed only during the dry season, the rarefaction curves indicate a satisfactory sampling effort. The data show that the Chico Mendes reserve holds a unique Amazonian bird community, which is influenced by the presence of bamboo and second growth vegetation. The results of this paper reinforce the biological importance of the RESEX and highlight the need for more inventories and bird studies at this isolated and little known region of the Brazilian Amazon.

Published: February 2022

Em seis das cerca de cinquenta ocorrências até agora identificadas nos municípios de Apuí, Novo Aripuanã e Manicoré, na região SE do estado do Amazonas, o manganês ocorre ao longo de camadas, lentes e laminações em siltitos e argilitos avermelhados, em crostas lateríticas manganesíferas e na forma de acumulações coluvionares. Romanechita é o principal mineral de manganês nessas ocorrências, com manjiroita, litioforita, holandita, vernardita, criptomelana e pirolusita subordinadas. Há duas associações geoquímicas principais: 1) a dos materiais manganesíferos: a) Sr, Au, U, Cu, Pb e Hg na ocorrência do Zé Julião; b) CaO, K2O, Zn, Tl, Rb, Cd, P2O5 e As nas fazendas Silva e Floresta; c) MnO, Ni, Mo, Be, Co, Ga e Eu nas de Beneficente, Cotovelo e Holanda; 2) a das rochas sedimentares, matriz e solo: d) Y + ETR - Eu; e) SiO2, Al2O3, TiO2, Nb, Hf, Zr, Fe2O3, Sc, Th, V. A gênese dos óxi-hidróxidos de manganês está relacionada à deposição em ambiente sedimentar e ao posterior processo de intemperismo e evolução da paisagem na região.

Published: February 2022

Cyperus articulatus e C. prolixus são conhecidas, respectivamente, como priprioca e pripriocão. Nessas espécies, há discordâncias quanto à nomenclatura de seus caules, que recebem denominações diversas, provocando dificuldades na identificação dos taxa. O presente estudo objetivou caracterizar os caules das duas espécies por meio da morfologia, morfometria, funcionalidade, anatomia e histoquímica. Os espécimes foram coletados em experimentos do campus Belém da Universidade Federal Rural da Amazônia (UFRA), sendo sua procedência do município de Acará, estado do Pará. O material foi descrito, mensurado e fixado em FAA70 seguindo-se, posteriormente, as práticas usuais em anatomia vegetal e testes histoquímicos. Os caules são dos tipos rizoma e cormo, subterrâneos, ambos plagiotrópicos e revestidos por catafilos. O rizoma é monopodial e cilíndrico, já o cormo é intumescido. Os dois caules são perenes; o cormo possui a função de propagação e o rizoma de expansão caulinar. Quanto à anatomia, os caules apresentam meristema de espessamento primário ativo, porém, apenas os cormos possuem meristema de espessamento secundário e produzem raízes adventícias.

Authors: Reich Michelle , Francelino Marcio Rocha
Published: February 2022

Nas últimas décadas, o estado do Acre vem apresentando crescente desmatamento, concentrado principalmente na região próxima da capital Rio Branco. O objetivo deste estudo foi avaliar o potencial de recuperação de Áreas de Proteção Permante (APP) de cursos d’água no município de Rio Branco, Acre. Foram utilizadas imagens orbitais do sensor TM do Landsat 5 para a criação do mapa de cobertura do solo de 2009. Realizou-se a sobreposição do mapa de cobertura do solo dentro das APP’s com os mapas de tipos de solos e de distância de fontes de propágulos, para obter-se o mapa final do potencial de recuperação. Mesmo protegidas por lei, Rio Branco apresenta cerca de 17% de suas áreas de APP’s de cursos d’água alteradas. Dos aspectos avaliados neste trabalho para determinação da resiliência, o tipo de solo demonstrou ser mais limitante e a distância de fontes de propágulos a mais potencializadora. A metodologia utilizada possibilitou estimar qual o percentual das áreas alteradas nestas APP’s que apresentam maior resiliência, o que possibilitaria a implantação de programas de recuperação mais adequados e de menor custo para cada área.

Towards a Formal Treatment of Logic Locking
Authors: Beerel Peter , Georgiou Marios , Hamlin Ben , Malozemoff Alex J. , Nuzzo Pierluigi
Published: February 2022

Logic locking aims to protect the intellectual property of a circuit from a fabricator by modifying the original logic of the circuit into a new “locked” circuit such that an entity without the key should not be able to learn anything about the original circuit. While logic locking provides a promising solution to outsourcing the fabrication of chips, unfortunately, several of the proposed logic locking systems have been broken. The lack of established secure techniques stems in part from the absence of a rigorous treatment toward a notion of security for logic locking, and the disconnection between practice and formalisms. We seek to address this gap by introducing formal definitions to capture the desired security of logic locking schemes. In doing so, we investigate prior definitional efforts in this space, and show that these notions either incorrectly model the desired security goals or fail to capture a natural “compositional” property that would be desirable in a logic locking system. Finally we move to constructions. First, we show that universal circuits satisfy our security notions. Second, we show that, in order to do better than universal circuits, cryptographic assumptions are necessary.

El siguiente trabajo de investigación tiene por objetivo visualizar y analizar el desarrollo socioeconómico de la Parroquia Rural Pilahuín a partir de una perspectiva del Desarrollo Rural y Local, siendo este uno de los lugares económicamente más activos y con una población indígena que de acuerdo con los datos mostrados por El Heraldo (2018) “está conformada por 12.128 habitantes, según datos del último censo realizado en el 2010, de los cuales, el 90% son indígenas y el 10% son mestizos”. (Párrafo 3) Sin embargo, dada la extensión de la población tanto en barrios y comunidades, se consideró primordial delimitar el estudio a la zona centro de la parroquia Pilahuín, al ser el lugar en el que se desarrollan las actividades comerciales y permite un muestreo aleatorio a partir de la población total de familias que son 569. En este sentido, es de suma importancia realizar investigación a una parroquia rural que representa un alto índice de pobreza a nivel nacional, por lo cual, es fundamental revisar el desarrollo de las condiciones de vida de sus habitantes y cómo la falta de políticas públicas e intervención gubernamental afecta el desarrollo social y económico de las familias, para ello, se empleó un método mixto en el que se realizó una recopilación bibliográfica-teórica del Desarrollo Rural y Local y posteriormente se analizaron e interpretaron los datos de una encuesta en la que se evidenciara el desarrollo socioeconómico de la zona centro de Pilahuín.
A Role of Udumbara Ksheer Sutra in Ano Rectal Fistula: An Ayurvedic Review
Authors: Anup Kumar  , Suman Yadav  , Ashutosh Kumar Yadav
Published: February 2022

Acharya Sushrut has involved Bhagandara among the Ashtamahagad (8 dreadful diseases). At first it is present as Pidika (boil/abscess) in Apakwa (non-suppurated) state, become Bhagandara when it becomes Pakwa (suppurated). As defined in modern science, it is associated with fistula in ano. An anal fistula is an abnormal track having an external opening in the perianal region and internal opening in the anal canal and/or rectum.

Ayurveda has a special approach to fistula management. All anal fistulas counter well to different forms of Kshar and Ksheer Sutra therapy. They are nothing but the medicated seton. The Ksheer sutra mechanical and chemical action of drugs coated on the thread work jointly to cut, cure, drain and clean the fistulous tract, thereby promoting track/wound healing. Though Bhrihattrayi, (chief three texts of Ayurveda) stated the use of Kshar Sutra, there is no proper description of their method of preparation. In eleventh century, Chakrapani Datta mentioned the preparation method of Ksheer sutra in his book Chakradatta for the first time which is indicated in Arsha and Bhagandara.

Apamarga Kshar Sutra is the standard Kshar Sutra, and but it has some disadvantages. A variety of other Kshar Sutra, as well as Ksheer Sutra, have been prepared to resolve these inconveniences of Apamarga Kshar Sutra. One of them is Udumbara Ksheer Sutra which was founded by Prof. P.J Deshpande and M.K Jalan in 1984. Udumbara is one among the Nyagradhadi Gana Dravya mentioned by Acharya Sushrut. He described in Bhagandara Chikitsa that the Nyagradhadi Gana Dravyas are Bhagandaranashak.
Pelvic Inflammatory Diseases- An Ayurvedic Perspective.
Authors: Matangee Pandya  , Shilpa Donga
Published: February 2022

Pelvic Inflammatory Disease (PID) is responsible for a considerable disease burden and represents an important healthcare issue in worldwide. PID is the clinical syndrome associated with upper genital tract infection and inflammation caused by the spread of micro-organisms from the lower to upper genital tract. Prevention of PID and recurrent PID is also a public health priority in the present scenario. Clinical signs and symptoms are relayed by clinician to diagnose PID, mainly due to the lack of a minimally or non-invasive diagnostic test that reliably identifies women with upper genital tract inflammation. Aim and objectives: The search for an Ayurveda equivalent of PID in Ayurveda classics doesn’t yield any one disease entity that entirely matches the clinical picture of this condition. Material and Methods: Diagnosis of PID is based on centers for disease control and prevention 2015 PID guideline. Considering it as ‘Anukta Vyadhi’ (unexplained disorder), this review attempts to understand the disorder by deriving its Vikaraprakriti (nature of disease), Adhishtanantarani (structures and sites affected), and Samutthanavishesha (specific etiological factor) based on a detailed analysis of the clinical features and other findings regarding the disease available in various textbooks and articles in the light of related references in Ayurvedic classics. Discussion and conclusion: PIDs are established in terms of Nidana Panchaka (five components of understanding a disease). Pittala and Paripluta Yonivyapad can be implied as pelvic inflammatory diseases

Published: February 2022

Tamaka shwasa is a Pitta Sthana Samudbava Pranavaha srotovikara in which the aggravated Kapha and Vata doshas plays a major role in causing Sthanasamshraya in the Pranavaha srotas, where Udrita kapha gets accumulated and causes obstruction to the normal movement of Prana Vata, which ends up in Pratiloma Gati of Vata producing the Lakshanas of Shwasa. This pathology is similar with that explained in modern i.e., bronchial asthma, where the inflammation of the airway is produced by broncho-constriction. The peak incidence of bronchial asthma is seen in 5 to 10 years of age group. Its prevalence range is 4 to 32% for 6 to 7 years old children. In childhood, there is a 2:1 male/female preponderance but the sex ratio gets equalizes by age 30. The prevalence of bronchial asthma is increasing by age worldwide. Nayopayam Kashayam and Vyaghryadi Kashayam having Vatakaphahara and Shawasahara property, mentioned in Arogya Raksha Kalpa Drumam and Ashtanga Hrdayam respectively are the formulations taken for the study

Today, countries that focus more on economic development considers the tourism industry as a major contributor to it. As one of the major field of tourism, ecotourism is seriously promoted. Estimating monetary value of environmental resources of ecosystem function is a method for understanding if the investments for conservation, improvement or revival of the environmental resources earned social welfare improvements. In this study, The recreational value of Bamo National Park (BNP) was estimated and measured using two methods of Contingent Value Method (CVM) and Travel Cost Method (TCM). The variables, inhabitance, distance from park, first visit, number of visit, deontologist, education, travel cost, visitors income, museum existence and existence of animal species were the effective variables on willingness to pay (WTP) of visitors in 2015. Monthly expected willingness to pay of Consequentialist and Deontologist visitors was US$ 2.08 and 2.47, respectively. Finally, the recreational value of Bamu Park, which were estimated in two methods was equivalent US$ 43940.47 and 79959.25, respectively, in 2015. The travel cost method used the market price information and it revealed there is willingness to pay and 90.7% of visitors have zone inhabitance. Further, travel cost function was ideal for the econometrics theoretical aspect and preferred using the travel cost method instead of contingent value method to valuating the Bamo National Park.

Contamination of lead in fishes from Laguna de Bay was previously recorded to have the highest concentrations that may pose a hazard to human health. However, no previous study was conducted on its biomagnification. This research is the first exploratory study that examined lead biomagnification in a food web of the lake. Water quality, aquatic communities, trophic levels and lead concentrations were analyzed during the dry and wet seasons. Lead concentrations were analyzed using Atomic Absorption Spectrometry. Levels of lead in the water were 0.05 mg L-1 and 0.03 mg L-1for dry and wet seasons, respectively. Lead concentrations increased in phytoplankton with 3.87 and 9.66 mg kg-1 lead during wet and dry season, respectively. Furthermore, lead levels increased in zooplankton with 2.92 and 14.31 mg kg-1 during wet and dry seasons, respectively. In fishes, the highest lead concentration in dry season was detected in Hypophthalmichthys nobilis with 0.38 mg kg-1 while the highest during wet season was observed in Oreochromis niloticus with 0.67 mg kg-1. Lead biomagnification was observed in this study in the following order: water < phytoplankton < zooplankton. However, this increasing trend did not continue up to fishes.

This study examined the involvement of women in agricultural decision-making among farming households in Ligao City, Albay, Philippines and related this to enhancement or decline of their adaptive capacity to extreme weather events. Data were collected through a household survey in the three selected barangays representing coastal, lowland and upland communities. More than 50% of husbands solely made decisions on choice of food crops, cash crops, tree species, and farm production. This parallel findings in the Philippines showing male dominance in agricultural production. Nevertheless, women still participated in decision-making in a limited way as 13-16% of them singly decided on behalf of the household while 30-38% made decisions together with the husband. Following the Sustainable Livelihood Framework, an adaptive capacity index was developed for the households. The analysis revealed that 96.17% of the respondents had low (<0.5) and 3.83% had medium adaptive capacity (>0.5), with all scores ranging from 0.0982 to 0.6171. Age and choice of trees species by husband positively influence adaptive capacity, while choice of cash crops by husband has negative relationship. Farm decision-making is gendered, and giving authority to the person with more capabilities to make effective decisions based on his/her relationship to this resource-based livelihood should be considered despite prevalent notion of the dominance of one gender.

Published: February 2022

Benthic marine macrophytes produce secondary metabolites which when released to the environment could potentially influence the immediate surroundings to the detriment of their competitors (i.e., other species of algae or phytoplankton). The response of the phytoplankton, Nanochlorum sp. to crude extracts (1% and 4% concentration) of the intertidal macrophytes Gracilaria salicornia, Chaetomorpha linum and Sargassum polycystum was investigated. On the average, there was a significant decrease (40-61% decrease at 4% conc. and 11-40% decrease at 1% conc.) in cell densities three days after the addition of the extracts relative to the control. Crude extracts of some common intertidal macrophytes may contain allelochemicals that could inhibit the growth of phytoplankton. The potential applications of these allelopathic effects in controlling phytoplankton blooms in small ponds and tanks have been suggested and needs further investigation.

Published: February 2022

Agroecosystem health refers to the extent to which a healthy agroecosystem can meet socioeconomic and biophysical needs of all residents over time. According to the attempts at assessing agroecosystem health, agroecosystem health depends on both functional and structural characteristics at regional level. However, both functional and structural characteristics have been altered from their natural state by industrialization and urbanization. Thus, this study reports a system-based assessment index to evaluate the health statue of agroecosystem in Guangzhou, South China. Agroecosystem health index (AHI) of Guangzhou decreased from 0.78 in 2000 to 0.71 in 2010. It indicated that this agroecosystem was at relatively healthy state. However, functions of both cultural service and economic sustainable development were not successful as they represented ‘worst’ and ‘sub-healthy’, respectively. With the decreased values between 0.7 and 0.9, the other indices also revealed the need for caution. Particularly, both habitat structure index and provisioning service index exhibited well defined declines during this study period. This study suggests that AHI can be potentially employed to monitor the temporal change in agroecosystem health status, although AHI has some certain limitations and needs further improvement for the complexity of agroecosystems.

Published: February 2022

Water samples collected from abandoned mining sites in Itogon, Benguet, Philippines were screened for metal resistant microorganisms, in particular yeasts that will be used to remove toxic metals such as Zn, Cu, Pb, Cr and Ni from aqueous media. Among the five yeast strains selected and five heavy metals tested, Nodulisporium sp. exhibited the highest removal efficiency of 80% and biosorption capacity of 56.7 mg g-1 for Pb. This was based on the model equation for each metal that was generated to derive optimum response for removal efficiency. The metal accumulation potential for all selected yeast isolates was generally higher at the lower initial metal concentration of 25 mg L-1, indicating rapid metal absorbing ability of the isolate and that adsorption sites in the biomass are taking up available metal ions more quickly. An increased removal capability was observed when the best isolate was applied in a semi-continuous treatment system thru an Aerobic Cascading Filter Bed Baffled Reactor (ACFBBR). The reactor design including the packing material remarkably enhanced the contact between the yeast biomass and Pb contaminated wastewater resulting in a much greater biosorption capacity of 170.14 mg g-1 as compared to the biosorption of 56.7 mg g-1 achieved during the batch adsorption experiment.

Influência do cordão de contorno no volume e qualidade da água de escoamento superficial em plantio de Eucalyptus sp.
Authors:   , Barbosa Sergio Guedes
Published: February 2022

A qualidade da água de uma bacia hidrográfica pode ser afetada por vários fatores antrópicos ou naturais, bem como da interação entre eles. O estudo das práticas de uso da terra no escoamento superficial e seus efeitos na carga de sedimentos do escoamento na perda de solo é essencial para a adoção de estratégias adequadas para controlar a erosão do solo e melhorar a qualidade das águas da microbacia. Áreas degradadas promovem, condição pra que ocorra maior escoamento superficial e erosão do solo em comparação ao ecossistema natural. Na ausência da cobertura vegetal natural as plantações florestais comerciais podem contribuir para a redução do escoamento da água e consequentemente, da erosão hídrica. O cultivo de espécies florestais com práticas de conservação do solo vem se constituindo em excelente aliado sob ponto de vista ambiental além de incorporar benefícios para a mitigação dos impactos causados pelo desmatamento e melhora dos parâmetros hidrológicos. As florestas plantadas têm importância econômica e ambiental. O estudo monitorou durante 8 anos em parcelas com diferentes declividades a distribuição de água de chuva e o uso de um método de conservação de solo em um plantio de eucalipto sob uma microbacia degradada, desde o plantio até a colheita, utilizando como parâmetro o coeficiente de escoamento superficial, turbidez, condutividade e pH da água. O método avaliado é o uso de cordão de contorno, o qual é amplamente utilizado em manejo de bacias hidrográficas. A combinação entre a cobertura vegetal proporcionada pela cultura do eucalipto e as práticas de terraceamento reduziu os percentuais de escoamento superficial em ambas as declividades estudadas e nos parâmetros físicos da água avaliados. Essa técnica pode ser divulgada para os produtores ruais da Zona da Mata Mineira. Palavras-chave: Hidrologia. Florestas plantadas. Áreas degradadas.
