Primordial germ cells do not migrate along nerve fibres in marmoset monkey and mouse embryos
Authors: Wolff E , Suplicki M M , Behr R
Published: November 2018

Primordial germ cells (PGCs) are the embryonic precursors of spermatozoa and eggs. In mammals, PGCs arise early in embryonic development and migrate from their tissue of specification over a significant distance to reach their destinations, the genital ridges. However, the exact mechanism of translocation is still debated. A study on human embryos demonstrated a very close spatial association between migrating PGCs and developing peripheral nerves. Thus, it was proposed that peripheral nerves act as guiding structures for migrating PGCs. The goal of the present study is to test whether the association between nerves and PGCs may be a human-specific finding or whether this represents a general strategy to guide PGCs in mammals. Therefore, we investigated embryos of different developmental stages from the mouse and a non-human primate, the marmoset monkey (Callithrix jacchus), covering the phase from PGC emergence to their arrival in the gonadal ridge. Embryo sections were immunohistochemically co-stained for tubulin beta-3 chain (TUBB3) to visualise neurons and Octamer-binding protein 4 (OCT4 (POU5F1)) as marker for PGCs. The distance between PGCs and the nearest detectable neuron was measured. We discovered that in all embryos analysed of both species, the majority of PGCs (>94%) was found at a minimum distance of 50 µm to the closest neuron and, more importantly, that the PGCs had reached the gonads before any TUBB3 signal could be detected in the vicinity of the gonads. In conclusion, our data indicate that PGC migration along peripheral nerves is not a general mechanism in mammals.
A Gene Expression Screen inDrosophila melanogasterIdentifies Novel JAK/STAT and EGFR Targets During Oogenesis
Authors: Wittes Julia , Schüpbach Trudi
Published: November 2018

The Janus Kinase/Signal Transducer and Activator of Transcription (JAK/STAT) and epidermal growth factor receptor (EGFR) signaling pathways are conserved regulators of tissue patterning, morphogenesis, and other cell biological processes. During Drosophila oogenesis, these pathways determine the fates of epithelial follicle cells (FCs). JAK/STAT and EGFR together specify a population of cells called the posterior follicle cells (PFCs), which signal to the oocyte to establish the embryonic axes. In this study, whole genome expression analysis was performed to identify genes activated by JAK/STAT and/or EGFR. We observed that 317 genes were transcriptionally upregulated in egg chambers with ectopic JAK/STAT and EGFR activity in the FCs. The list was enriched for genes encoding extracellular matrix (ECM) components and ECM-associated proteins. We tested 69 candidates for a role in axis establishment using RNAi knockdown in the FCs. We report that the signaling protein Semaphorin 1b becomes enriched in the PFCs in response to JAK/STAT and EGFR. We also identified ADAM metallopeptidase with thrombospondin type 1 motif A (AdamTS-A) as a novel target of JAK/STAT in the FCs that regulates egg chamber shape. AdamTS-A mRNA becomes enriched at the anterior and posterior poles of the egg chamber at stages 6 to 7 and is regulated by JAK/STAT. Altering AdamTS-A expression in the poles or middle of the egg chamber produces rounder egg chambers. We propose that AdamTS-A regulates egg shape by remodeling the basement membrane.

Authors: Milet Beatriz , Chuo John , Nilan Kathleen , Warren Karen , McKenna Kristin , Carroll Jean M. , Evans Jacquelyn , Zhang Huayan
Published: November 2018

OBJECTIVES:

Immunizations provide important protection from serious childhood illnesses. Infant chronic lung disease (CLD) is a serious complication of prematurity and predisposes premature infants to respiratory morbidity, rehospitalization, and mortality. This high-risk group is especially vulnerable to infections, such as invasive pneumococcal disease, influenza, and bronchiolitis. Our purpose for this project was to increase 2-, 4-, and 6-month immunization rates in eligible infants with CLD in the NICU by 30% through December 2016.

METHODS:

A multidisciplinary team developed weekly targeted rounds to identify eligible patients with outstanding immunizations. Exclusion criteria included the following: (1) a fraction of inspired oxygen requirement of >80%, (2) pulmonary hypertensive crisis, (3) positive blood culture results or if within 48 hours of a sepsis evaluation, (4) if within 5 days of a surgical or interventional procedure, (5) receiving steroid treatment (not including a physiologic hydrocortisone dose for adrenal insufficiency), (6) a CLD team consensus of contraindication, and (7) parental refusal.

RESULTS:

The project managed 60 patients from March 2016 to December 2016. Immunization of eligible patients increased from 44% to 75% and was sustained for the next 6 months. The average number of days from admission to immunization record review decreased from 71 days at baseline to 27 days.

CONCLUSIONS:

The implementation of (1) an in-hospital immunization record review, (2) an e-mail reminder, (3) a weekly multidisciplinary eligibility discussion, and (4) an updated rounding tool was successful in increasing and sustaining immunization rates in this population of infants with CLD. The multidisciplinary CLD meeting was a novel opportunity to discuss immunization eligibility and safety monitoring.
Involving Youth With a Chronic Illness in Decision-making: Highlighting the Role of Providers
Authors: Miller Victoria A.
Published: November 2018

Decision-making is important in the context of pediatric chronic illness because children and families need to make decisions about burdensome and complex treatments on a regular basis, and children must eventually learn how to make such decisions independently. Research related to children’s decision-making in medical settings has been focused primarily on cognitive aspects of decision-making, such as understanding and capacity. The concept of decision-making involvement (DMI) recognizes that children can be involved in decision-making in multiple ways, regardless of capacity, and that parents and health care providers play a critical role in supporting children as they learn to make decisions on their own. Providers can facilitate DMI during medical encounters by asking for the children’s opinions and concerns, encouraging turn-taking, soliciting questions, asking for information directly from the children, and checking that the children understand what has been said. Efforts to involve children send the message that the youth perspective is important and set the expectation for increased participation over time. Providers can also support parent-child decision-making about illness management at home by guiding parents as to how best to involve children in decisions about illness management, identifying areas in which more or less parental guidance and support are needed, and assisting youth in planning ahead for decision-making about illness management in high-risk situations. Additional research is needed to identify why children’s DMI in medical settings remains low, develop and evaluate strategies to enhance DMI, and test the effects of DMI on health-related behaviors and outcomes over time.
Pragmatic Strategies for Shared Decision-making
Authors: Walter Jennifer K. , Hwang Jennifer , Fiks Alexander G.
Published: November 2018

Shared decision-making (SDM) is a process that brings together clinical expertise and families’ values to arrive at a treatment choice. The process is especially useful for situations with >1 reasonable option, a condition of equipoise. However, for pediatricians who want to adhere to SDM best practices, there is limited practical guidance regarding how to communicate with parents and patients. With the following text, we describe pragmatic strategies to support SDM around both high-stakes decisions in the acute setting as well as in the ongoing management of chronic conditions in settings such as primary care.

This Policy Statement was reaffirmed January 2024.

This is a revision of the previous joint Policy Statement titled “Guidelines for Care of Children in the Emergency Department.” Children have unique physical and psychosocial needs that are heightened in the setting of serious or life-threatening emergencies. The majority of children who are ill and injured are brought to community hospital emergency departments (EDs) by virtue of proximity. It is therefore imperative that all EDs have the appropriate resources (medications, equipment, policies, and education) and capable staff to provide effective emergency care for children. In this Policy Statement, we outline the resources necessary for EDs to stand ready to care for children of all ages. These recommendations are consistent with the recommendations of the Institute of Medicine (now called the National Academy of Medicine) in its report “The Future of Emergency Care in the US Health System.” Although resources within emergency and trauma care systems vary locally, regionally, and nationally, it is essential that ED staff, administrators, and medical directors seek to meet or exceed these recommendations to ensure that high-quality emergency care is available for all children. These updated recommendations are intended to serve as a resource for clinical and administrative leadership in EDs as they strive to improve their readiness for children of all ages.
Phraseology, argumentation and identity in the Supreme Court of Ireland's judgments on language policy
Authors: Mazzi Davide
Published: November 2018

The Irish judiciary's approach to bilingualism as the constitutional guarantee of the right to use either Irish or English for any official purpose has proved highly flexible. However, while emphasis has been laid on principles of constitutional interpretation from the practitioner's perspective, the discursive dimension of cases involving language policy has yet to be fully elucidated. This paper combines quantitative analysis with a qualitative perspective to focus on phraseological and argumentative patterns in Supreme Court judgments on language policy, based on a small corpus. First, the ten most frequent lexical bundles of the corpus were extracted to study the main discourse functions of phraseology in context. Second, a manual text analysis was conducted of the two cases where recurrent phraseological patterns were most widely attested. This allowed for the isolation of the argument schemes underlying the structure of the Justices’ opinions. While phraseology points to a shared institutional identity of Irish Justices as gatekeepers of the Constitution, the use of argumentative patterns suggests that they may forge heterogeneous professional identities, by shifting from a rigouristic view of language rights to forms of judicial pragmatism.
The joint production of confession in qualitative research interviews
Authors: Aarsand Liselott , Aarsand Pål
Published: November 2018

Uncovering the self and telling the ‘truth’ about who we are, or to confess, is a widespread social phenomenon in contemporary Western societies. The present article moves beyond a preoccupation with confession as revealing inner thoughts, shortcomings and aspirations to rather seeing it as a particular way to speak. The data material consists of 20 qualitative research interviews from two distinct research projects, where the analytical focus is on how confessional talk is initiated and managed in situ. The findings show that confessional talk emerges and is established differently following the pattern of being self-initiated, other-initiated or co-initiated. Accordingly, confession is not necessarily the consequence of a particular question from an interviewer, or a single response from an interviewee, but is developed in and through a course of interaction with contributions from all interlocutors. By highlighting the dynamic work within the interview sequences, the findings may contribute to the lively debate on how to theorize and analyze qualitative interviewing. To better capture the complexities of interviewing, a slight shift – from the role of the interviewer to the role(s) of the researcher – is suggested, which calls for more focus on the particular frame of qualitative research.
Wali, Sultan, Kiai, dan Santri dalam Tadisi Agama dan Politik Islam Jawa
Authors: Chalik Abdul
Published: November 2018

The article discusses the role of wali (the Muslim saints), sultan, kiai, and santri within religious tradition and politics in Java. The wali (commonly known as Walisongo or “the Nine Saints”) were people who initially spread Islam in Java. In their efforts to develop Islam, Walisongo also equipped their pupils with religious knowledge to spread Islam in the future. This is from such process the transfer of Islamic knowledge was primarily set off. Once the transition periods began, the role of wali had subsequently vanished and replaced by the formal ruler, namely sultan. The Mataram Sultanate was the biggest Islamic sultanate ever in the history of Java. Owing to the supremacy of the Sultan, Kiai Kasan Besari—as an ample example of kiai mentioned in this article—built a pesantren in an area called tanah perdikan (a tax haven) in Tegalsari Ponorogo, East Java, which became an origin of institutionalization of the pesantren in Java. The Sultan provided the pesantren both material aids and other kinds of support, including entrusting his sons to learn religious knowledge in it. It had been also followed by the royal courtiers and the best cadres of the sultanate who subsequently became litterateurs of the Kingdom.
Genealogi dan Corak Studi Kalâm di Indonesia
Authors: Zuhri Zuhri
Published: November 2018

The discourse of kalâm (Islamic theology) in Indonesia has its long historical root. The discourse has initially emerged alongside the process of the spread of Islam in Indonesia. The dynamics of the discourse among various segments of the Indonesian Muslim society have found their rhythm from time to time. It should be noted, however, that the discourse has not yet found its genealogical pattern. This article, therefore, attempts to find the genealogical foundation and the pattern of studies of kalâm in Indonesia together with its trends. The developing reasoning of kalâm in the mediaeval periods of Islam, i.e. after the 12th century, tended to be strong in terms of its orthodoxy compare to the discourse itself. This subsequently becomes a source of inspiration for the discourse of kalâm in Indonesia until nowadays. As a result, there has been a sort of general trend that the study of kalâm in Indonesia has remained stagnant. It can be, among other, observed from the process of studying kalâm as knowledge reference, its development and formalization, and critique of the discourse, which indicate unprosperous condition for the discourse itself.
Tren Pengembangan Ilmu di Universitas Islam Negeri Maulana Malik Ibrahim Malang
Authors: Muslih Mohammad
Published: November 2018

It has been over a decade, in which the journey of State Islamic University (UIN) Malang in developing new scientific paradigm has appeared to be quite successful, particularly in establishing and developing an “image” of Islamic-based sciences in their new forms. The success can be observed from, among other, people’s demand—from various segments of the society—to a number of books written by the lecturers of UIN Malang. Such tremendously remarkable achievement becomes certainly a worthy matter to observe and discuss, especially from the Philosophy of Science’s point of view concerning on how the pattern of scientific development—as a part of academic traditions—built by this Islamic higher educational institution. This article finds an important information that the development of science in UIN Malang has arrived upon the development of new theories and concepts, by placing al-Qur’ân and al-Sunnah as its main and fundamental foundations. It can be generally observed that there has been a sort of a pattern of “Quranic justification” to the sciences developed by UIN Malang. It means that any scientific activity is intended to prove the “scientificness” of al-Qur’ân. It has been also assumed, moreover, that al-Qur’ân is the book of science.
Dualisme dalam Kesatuan untuk Mencapai Maʻrifah Perspektif KH. Asrori Ishaqi
Authors: Rahmatullah Muhammad
Published: November 2018

The article reveals the concept of dualism in unity along with maʻrifah in KH. Asrori Ishaqi’s perspective. This article finds that dualism in unity to reach maʻrifah in Kiai Asrori’s perspective rests in his conception about God through what so-called al-Ah}ad and al-Wâḥid as well as al-Wujûd and al-Kawn. He emphasizes that there is no al-Wujûd (existence) but Allah’s. It is, therefore, all creatures’ existence is embraced within God’s existence. Al-Kawn—on the other side—is everything which exists and will exist, in which God has known them already and determined their fate. The concept of al-Aḥad emphasizes that Allah is All The One in His Essence in advance of His Asmâ’ (Names) and Attributes. Al-Wâḥid means All The One in His Asmâ’ and Attributes after the emanation of the two over His creatures. In accordance with human’s existence, Kiai Asrori states that humans are created from spiritual realm and the physical one. It seems that Kiai Asrori would emphasize that though Allah is The Almighty and unreachable, the humans can still—in another dimension—reach Him through the emanation of His Asmâ’ with murâqabah using their reasons, understanding, and hearts. Kiai Asrori is an advocate to monistic Sufism and at the same time he also a proponent of dualistic Sufism.
Relasi antara Tuhan dan Manusia Menurut Pandangan Ibrāhīm al-Kurānī
Authors: Mubarok Frenky
Published: November 2018

This article describes the concepts of relationship of God and man from theological point of view along with Sufism. It focuses on Ibrāhīm al-Kurānī’s view on the issue. This article confirms that al-Kurānī attempts to reconcile theological views of Ash‘arīyah and the divine worldviews of the Sufis, especially that of Ibn ‘Arabī’s philosophical Sufism. Al-Kurānī argues that there has been interconnectedness between common concepts expressed by the Sufis such as waḥdat al-wujūd and tajallī and the concept of al-kasb promulgated by Ash‘arīyah. The author finds that the concepts of ittiḥād and ḥulūl are not two mystical concepts that explain the relationship of God and man, rather these two concepts are a mere psychological condition sensed and experienced by the Sufis who try to enter the realm of ma‘rifat. Al-Kūrānī also argues that the relation of God and man can be explained through the concept of tajallī. He sees that this concept is compatible with Ash‘arīyah’s concept of al-kasb. Al-Kūrānī adds that causality is not an undoubtedly exact matter. It means that the causality does not discord against the notion of waḥdat al-wujūd.
Rekonstruksi Pemikiran dan Posisi Sufi-Antisufi Ibn Taymīyah
Authors: Zamzami Mukhammad
Published: November 2018

This article reanalyzes Ibn Taymīyah’s position and his thought in Sufism and anti-Sufism. The article is also expected to find the precise typology to describe the qualification of Ibn Taymīyah’s Sufism other than the Sunnī and Falsafī typologies. As a formalist and literalist thinker, Ibn Taymīyah has been famously known as an anti-Sufi Muslim scholar. There have been a number of modern Salafis who refute any relationship of Ibn Taymīyah and Sufism. Ibn Taymīyah has criticized such philosophical doctrines of Sufism as waḥdat al-wujūd, ḥulūl, and ittiḥād, which are considered to have deviated from the foundations of Islam. Along with his criticism, Ibn Taymīyah offers solution by recovering the earliest and authentic traditions of Sufism when it is viewed as to have obscured the authenticity of knowledge based on the al-Qur’ān and Sunnah. The product of his Sufism can be, therefore, categorized in Salafi-Sufism typology in addition to other such pIbn Taymīyahopular typologies as Sunnī and Falsafī. The pattern of the Taṣawwuf Salafī—which is deemed as being appropriate to describe the existence of Ibn Taymīyah’s Sufism—does not, basically, accept takwil upon the religious texts. The aim of his Sufism is to strengthen one’s faith and help him/her to purify their soul and morality
Karakter Historis Sufisme pada Masa Klasik, Modern, dan Kontemporer
Authors: Huda Sokhi
Published: November 2018

Sufism is an actualization of the doctrine of Tasawuf about purification of the soul towards God as a form of realization of the Prophet’s hadith on al-iḥsān. Sufism presents three forms of activity, namely the purification of the soul, Sufi behavior, and Sufi movements. Historically, Sufism has featured a distinctive and dialectical character. Classical Sufism features five characters, namely ascetic, practical, asceticism driven by fear of God, the concept of maḥabbah, and the concept of maḥabbah for ma‘rifah. Modern Sufism features four characters, namely presentation of sharī‘ah-based Sufism with no prominent social role any longer, adaptability to modern environments, expression of new political role as a pioneer of the modern nationalist movement, expression of Sufi militancy movement in the late colonial context. Contemporary Sufism presents nine characters, namely Sufism as a variant of transnationalism, the change in the relationship of authority and pattern of association in Sufism, the emphasis of Sufism as a mean of dedication, accommodative attitude towards the new regime, Sufism as the basis of civil society for political mobilization, the development of unique forms of local voluntary associations, the solution-based attitude of Sufism in political archetype, merging of Sufism with the spirit of Salafi and political activism, and the existence of relations of globalization, transnationalism, and hybridity.
Relasi Murshid dan Murid dalam Bimbingan Tarekat Shâdhilîyah di Pesulukan Thoriqot Agung Tulungagung
Authors: Musthofa Chabib
Published: November 2018

This article attempts to reveal the relation of murshid and murīd (pupil) of the Tarekat Shādhilīyah at Pesulukan Thoriqot Agung (PETA) in Tulungagung East Java. The author discusses the pattern of constructive relation between murshid and his pupils to build an objective social reality of the tarekat in terms of its teaching and ritual aspects. This moment subsequently becomes a medium of adaptation of the pupils. It helps the pupils to reach the process of spiritual happiness and internalize it into his/her consciousness and behaviors. Within such relation, social construction affirms that community is a result of human’s production and it stands beyond the zone of an external phenomenon. This external phenomenon consists of material and non-material subjects. In time, the external phenomenon becomes an objective reality, which forms understanding and behavior of other people in other different periods. Murshid has been the main subject within a tarekat who is capable to color spiritual realm of his pupils. The plot of murabbī al-rūḥ (spiritual educator) attached upon murshid is not a mysteriously hidden, abstract, and unseen epithet. Instead, this spiritual status is applied in his social action and behavior and it colors the spiritual actions of his murīd.
Sunan Ampel dan Nilai Etis Islam Nusantara: dari Tantra-Bhairawa kepada Praktik Keagamaan Nir-Kekerasan
Authors: Mukaffa Zumrotul
Published: November 2018

This article focuses its discussion on the order of ethical values behind the success of Sunan Ampel, one of the Nine Saints (Walisongo), to co-modify the Pancamakara ritual that involves the Tantra-Bhairawa sect during the era of Majapahit Kingdom. The Pancamakara has been also called as Pancamakara Puja, Cakra Puja, Mo-Limo or Panca Ma, which stand on five basic elements, namely mamsa, matsya, madya, maithuna, and mudra. The study finds that Sunan Ampel had successfully created the concept of Pancamakara and its sustainability as exchange values with Islam with no intention to totally deconstruct its utility values. The value order consists of certainty to always emphasize islamization and to bridge Islam and local religious rituals in order to achieve peaceful and non-violent religious practices. The value order is transformed into existing pattern of culture. Consequently, the implementation pattern of Pancamakara as religious ritual had still been preserved but its substance was entirely deconstructed. Through his magical touch, Sunan Ampel had preserved Pancamakara that had no longer based on the five basic elements called Mo-Limo. Instead, the doctrine commands people to avoid the five basic elements and it now becomes Moh-Limo (unwilling to commit five immoral acts).
Rigiditas dan Fleksibilitas Diskursus Fiqih Wanita Hizbut Tahrir
Authors: Chaidaroh Umi
Published: November 2018

Many women in modern times take part in public spaces. Moreover, women are also involved with Islamic movements which are often associated as fundamentalist movements such as Hizbut Tahrir (HT). In Indonesia, HT has a wing of women’s organization called the Muslimah Hizbut Tahrir Indonesia (MHTI). Women’s activists play pivotal role in the public space to help HT achieve its goals. Fundamentalist women who work in the public sphere seem to contradict with the growing assumption asserting that Islamic fundamentalist movements are often associated with the magnitude of oppression against women. It has been, however, seems to be a paradox. Considering the aforement-ioned argument, it is important to examine the thoughts concerning women’s jurisprudence of HT. Using compara-tive approach this study focuses on written literature as the main source. The results of the study prove that the thought concerning women’s jurisprudence of HT tends to be rigid. Interestingly, however, the study also finds that within particular cases the jurisprudence shows its flexibility, but it is even can be called liberal.

Assim, os objetivos deste trabalho foram estudar o efeito da qualidade da água sobre o desenvolvimento de obstruções, bem como testar a eficiência de dois tipos de ácidos no controle dessas obstruções. O experimento foi instalado no delineamento inteiramente aleatorizado, no esquema fatorial 4x2 com duas repetições. Os tratamentos foram quatro tipos de água e dois ácidos (nítrico e clorídrico). Foi feita uma avaliação do sistema antes e outra após a acidificação. Para cada tratamento foram calculados a vazão, o coeficiente de variação de fabricação e a uniformidade de emissão. A qualidade da água de irrigação não influenciou a vazão, o coeficiente de variação de fabricação e a uniformidade de emissão. O uso de ácido nítrico e clorídrico foi eficiente no controle de obstruções. O uso do ácido clorídrico fica limitado a águas com menores teores de bicarbonatos. UNITERMOS: Gotejamento, qualidade de água, uniformidade de emissão, acidificação  SILVA JÚNIOR, M.

Clogging is a consequence that reduces emission uniformity. Thus, this paper aimed to study water quality effect on the development of clogging and efficiency of acid types in clogging control. The experiment was installed in a completely randomized design with a 4x2 factorial scheme and two replications. The treatments were four types of water and two acids (nitric and hydrochloric). System evaluations were made before and after the acidification. For each treatment the following were calculated:  flow, manufacturer’s variation coefficient and emission uniformity. Water quality did not affect flow, manufacturer’s variation coefficient and emission uniformity. The use of nitric and hydrochloric acids was efficiency on clogging control. The use of hydrochloric acid is limited to waters with low bicarbonate levels. KEYWORDS: Drip irrigation, water quality, emission uniformity, acidification

Aliado a isto, a capacidade de manuseio de grande volume de dados dos computadores pessoais atuais, facilita a criação e aplicação de novas ferramentas para análise de informações. Neste trabalho objetivou-se a aplicação de uma matriz de partição fuzzy para análise os dados obtidos pelo sensor TM do satélite Landsat 5, visando elaborar a classificação supervisionada do uso da terra na microbacia hidrográfica do Arroio das Pombas, no Município de Botucatu, SP. A atribuição de pesos no momento da criação das assinaturas, possibilitou que uma simples área de treinamento oferecesse entrada em mais de uma classe de cobertura. Constatou-se, também, uma modificação no resultado da classificação quando comparada com a classificação por máxima verossimilhança, principalmente com relação à maior homogeneidade e melhor definição das bordas das classes. UNITERMOS: matrix de partição fuzzy, classificação supervisionada, imagem de satélite.  CAMPOS, S., PIROLI, E.L., ZIMBACK, C.R.L., RODRIGUES, J.B.T.ANALYSIS OF SOIL USE IN A MICROBASIN USING A FUZZY PARTITION MATRIX  2 ABSTRACT Informatics evolution presently offers the possibility of new technique and methodology development for studies in all human knowledge areas. In addition, the present personal computer capacity of handling a large volume of data makes the creation and application of new analysis tools easy. This paper aimed the application of a fuzzy partition matrix to analyze data obtained from the Landsat 5 TMN sensor, in order to elaborate the supervised classification of land use in Arroio das Pombas microbasin, in Botucatu,SP,Brazil. It was possible that one single training area present input in more than one covering class due to weight attribution at the signature creation moment.

Para a utilização dessas águas residuárias na fertirrigação, conhecer alguns parâmetros como condutividade elétrica e a série de sólidos são necessárias. Objetivou-se com este trabalho, avaliar a relação entre condutividade elétrica e sólidos de diferentes águas residuárias. Coletou-se águas residuárias de suinocultura, laticínio, doméstico e industrial e determinou-se analiticamente a condutividade elétrica, sólidos totais, fixos, voláteis, suspensos e dissolvidos. Os resultados mostraram que há uma relação linear para a condutividade em função dos sólidos totais e dissolvidos em sua maioria, em todas as águas residuárias, exceto para a água residuária doméstico, entre a condutividade e sólidos fixos há uma relação linear somente para a água residuária de laticínio, sendo que nos demais sólidos não observou-se uma relação com a condutividade elétrica em nenhuma das águas residuária estudadas. UNITERMOS: Reúso, condutividade elétrica, águas residuárias.  SAMPAIO, S.C.; SILVESTRO, M.G.; FRIGO, E.P.; BORGES, C.M.;RELATION BETWEEN SOLID SERIES AND ELECTRICAL CONDUCTIVITY IN DIFFERENT WASTEWATER  2 ABSTRACT Agricultural wastewater use preserves potable water and allows an optimization of the hidric resorts available, extending the offering of a more and more scarce product.
