p.97-100Se determinó en campo el efecto de distintas poblaciones de larvas de Epilachna paenulata Germ, sobre el rendimiento de zapallito redondo de tronco. Pudo comprobarse que poblaciones inferiores a 5 larvas por planta, a partir de 5 hojas verdaderas hasta cosecha, no afectan el rendimiento expresado en gramos de zapallitos por planta. También se determinó la relación entre las distintas densidades de plaga y las pérdidas y se obtuvo un modelo predictivo del rendimiento
Development of the Integrated Model of the Automotive Product Quality Assessment
Issues on building an integrated model of the automotive product quality assessment are studied herein basing on widely applicable methods and models of the quality assessment. A conceptual model of the automotive product quality system meeting customer requirements has been developed. Typical characteristics of modern industrial production are an increase in the production dynamism that determines the product properties; a continuous increase in the volume of information required for decision-making, an increased role of knowledge and high technologies implementing absolutely new scientific and technical ideas. To solve the problem of increasing the automotive product quality, a conceptual structural and hierarchical model is offered to ensure its quality as a closed system with feedback between the regulatory, manufacturing, and information modules, responsible for formation of the product quality at all stages of its life cycle. The three module model of the system of the industrial product quality assurance is considered to be universal and to give the opportunity to explore processes of any complexity while solving theoretical and practical problems of the quality assessment and prediction for products for various purposes, including automotive
Dissociation and Sexual Trauma: The Moderating Role of Somatization
This study examined various types of trauma, with an emphasis on sexual trauma across the lifespan, in a clinical sample of male and female adult outpatients assessed for trauma, somatization, and dissociation. Two hundred forty-five adult outpatients at the University of Tennessee Psychological Clinic were administered the Dissociative Experiences Scale (DES), the Traumatic Experiences Checklist (TEC), and Symptom Checklist-90-Revised (SCL-90-R), as part of the routine intake procedure. Of those individuals, 200 patients completed the questionnaires correctly and were included in the final study sample. The experience of sexual trauma indeed accounted for additional variance in somatization scores over and above the experience of other types of trauma, although it did not account for additional variance in dissociation scores. Also somatization was significantly correlated with dissociation. On the other hand, gender did not significantly increase the likelihood of having greater somatization. Furthermore, somatization did not significantly moderate the relationship between trauma and dissociation nor did it affect the non-significant relationship between gender and dissociation. Also, surprisingly in this sample, age of onset of sexual trauma did not significantly increase the likelihood of having greater dissociation or somatization. Finally, the experience of having a family member perpetrator did not account for additional variance in dissociation or somatization scores over and above having a non-family member perpetrator
Relationship of Age of Onset and Other Dimensions of Trauma to Dissociation in an Adult Clinical Population
This study examined four dimensions of trauma and how they affected levels of dissociation in male and female adult outpatients. These dimensions are age of onset, multiple trauma, chronicity, and recency. Two hundred forty-five adult outpatients at the University of Tennessee Psychological Clinic were administered the Dissociative Experiences Scale (DES) and the Traumatic Experiences Checklist (TEC) as part of the routine intake procedure. Of those individuals, 177 patients reported trauma and were included in the final study sample. All four dimensions of trauma were found to be significantly correlated with dissociation. In addition, multiple trauma was found to be the most important factor contributing to the participants’ dissociation. An interaction was also found between age of subject at time of assessment and recency. Finally, gender moderated the effect of age of onset on dissociation scores. Ultimately multiple trauma, despite age of onset, chronicity, or recency, has the most weight when conceptualizing the complex relationship between dissociation and trauma
Treatment of hepatitis C in injecting drug users in the Perth metropolitan area
This study used a sequential exploratory mixed methods research to develop a better understanding of the context of treatment intentions of IDUs living with HCV in Perth Metropolitan area. Sixty three percent of participants expressed that they had intention to uptake HCV treatment. Characteristics of treatment, stigma and lack of support emerged as factors influencing intention to uptake HCV treatment. The findings will help to make the world a better place by scaling up HCV treatment for IDUs in the community setting
Hyaluronan Rafts on Airway Epithelial Cells
Many cells, including murine airway epithelial cells, respond to a variety of inflammatory stimuli by synthesizing leukocyte-adhesive hyaluronan cables that remain attached to their cell surfaces. This study shows that air-liquid interface cultures of murine airway epithelial cells (AECs) also actively synthesize and release a majority of their HA onto their ciliated apical surfaces to form a heavy chain-hyaluronan (HC-HA) matrix in the absence of inflammatory stimuli. These matrices do not resemble the rope-like HA cables, but occur in distinct sheets, or rafts, that can capture and embed leukocytes from cell suspensions. The HC-HA modification involves the transfer of heavy chains from the inter-a-inhibitor (IaI) proteoglycan, which has 2 heavy chains (HC1 and HC2) on its chondroitin sulfate (CS) chain. The tranesterification transfer of HCs from CS to HA is mediated by tumor-necrosis-factor-induced-gene 6 (TSG-6), which is upregulated in inflammatory reactions. Because the AEC cultures do not have TSG-6 nor serum, which is the source of IaI, assays for HCs and TSG-6 were done and showed that AECs synthesize TSG-6 and their own heavy chain donor (pre-IaI) with a single heavy chain 3 (HC3), which is the substrate for transfer to HA to form the H3-HA rafts. This HC3 pre-IaI is also constitutively expressed by human renal proximal tubular epithelial cells. These leukocyte adhesive HC3-HA structures were also found in the bronchoalveolar lavage (BAL) of naive mice, and were observed on their apical ciliated surfaces. Thus, these leukocyte-adhesive HA rafts are now identified as HC3-HA complexes that could be part of a host defense mechanism filling some important gaps in our current understanding of murine airway epithelial biology and secretion

The world is established through the work of existence : the performance of Gham-Khadi among Pukhtun Bibiane in Northern Pakistan.
This thesis explores the social lives of elite Pukhtun women or Bibiane in
northern Pakistan, with an ethnographic focus on the enactment of particular life-cycle
or gham-khadi ceremonies (funerals and weddings). The widely used Pukhto term ghamkhadi
both refers to specific segregated gatherings and designates the emotions of
sorrow (gham) and joy (khada) which they elicit. In the local understanding, gham-khadi
comprises a system of life, in which happiness and sadness are understood as
indissoluble, and are celebrated communally within networks of reciprocal social
obligations. Bibiane's social role entails preparation for and attendance at gham-khadi,
according to a stylized set of performances thought integral to Pukhtun identity or
Pukhtunwali (ideal Pukhtun practices). In this sense, the "women's work" of gham-khadi
links with another indigenous term, tieest-roý.g ar, which I translate as the "work of
existence", and through which Bibiane maintain the fabric of life by sustaining social
inter- and intra-family relationships. Ethnographic fieldwork, conducted in Islamabad
and the North-West Frontier Province (NWFP or "Frontier") regions of Swat and
Mardan between 1996-1998 and 1999-2001, suggests the extent to which Bibiane's sense
of their gham-khadi obligations underpins their understanding of their personhood. In
the process, the thesis unfolds a Pukhtun construction of work divergent from
professionalism or physical labour, in which work produces not things, but social
relations and transactions.
This thesis, therefore, seeks to contribute to anthropological debate on a
number of issues. First, it seeks to establish the distinctive sociality of Pukhtun Bibiane
in terms of their participation, within and beyond the household, in gham-khadi
festivities, joining them with hundreds of individuals from different families and social
backgrounds. Second, the thesis makes a case for documenting the lives of a grouping
of elite South Asian women, contesting their conventional representation as "idle" by
illustrating their commitment to various forms of work within familial and social
contexts. Third, it describes the segregated zones of gham-khadi as a space of female
agency. Reconstructing the terms of this agency helps us to revise previous
anthropological accounts of Pukhtun society, which project Pukhlunwali in
predominantly masculine terms, while depicting gham-khadi as an entirely feminine
category. Bibiane's gham-khadi performances allow a reflection upon Pukhtunwali and
wider Pukhtun society as currently undergoing transformation. Fourth, as a contribution
to Frontier ethnography, the thesis lays especial emphasis on gham-khadi as a
transregional phenomenon, given the relocation of most Pukhtun families to the
cosmopolitan capital Islamabad. Since gham-khadi is held at families' ancestral homes
(kille-koroona), new variations and interpretations of conventional practices penetrate to
the village context of Swat and Mardan. Ceremonies are especially subject to negotiation
as relatively young convent-educated married Bibiane take issue with their "customs"
(rewaý) from a scriptural Islamic perspective. More broadly, the dissertation contributes
to various anthropological topics, notably the nature and expression of elite cultures and
issues of sociality, funerals and marriage, custom and religion, space and gender,
morality and reason, and social role and personhood within the contexts of Middle-
Eastern and South Asian Islam
