Opis:
Background: Mucormycosis is a rare fungal infection affecting people with impaired immunity. The aim of this study is to shed light on the epidemiology, incidence, and outcome of patients with mucormycosis hospitalized at a tertiary care center in Pondicherry. Methods: We conducted a retrospective chart review between January 2008 and January 2018. All patients with proven or probable mucormycosis were included. Results: A total of 24 patients were included. Their median age was 49 years and the majority were males. Comorbidities included mainly hematologic malignancy and diabetes mellitus. A liposomal amphotericin B formulation alone or in combination with other antifungals was used as a first line agent in all patients. Conclusion: The incidence of mucormycosis has significantly increased over the past 10 years at our institution, most likely due to increased risk factors.

Opis:
Two tri-component mixtures as base mixtures for vertically aligned mode LCD's were prepared. The eutectic compositions were theoretically estimated and experimentally verified from differential scanning calorimetry studies. A room temperature nematic mixture with fairly broad operating range emerged from each of the tri-component mixtures. The optical birefringence of these mixtures at the eutectic composition was measured as a function of temperature. X-ray diffraction measurements were done on these mixtures to obtain the orientational order parameters as a function of temperature. The order parameter values were also determined from birefringence measurements and the results were compared with mean field theory. Structural parameters like intermolecular distance and apparent molecular length have also been determined.

Opis:
Two tricomponent room temperature nematic eutectic mixtures ABC and ABD with laterally fluorinated constituents A and B were prepared as base mixtures for vertically aligned mode LCD's. The physical properties of these mixtures viz. birefringence, dielectric anisotropy, bend elastic constant, relaxation time and rotational viscosities were determined in order to compare with the optimum values required to achieve the target specifications of VA mode materials. The dielectric anisotropy, Δ ε, and optical birefringence, Δ n, of these mixtures were found to be in the range of (-1.3 to -1.4) and (0.13 and 0.14), respectively, at around 20°C. The figure of merit for the ABD mixture has been found to be higher than that of ABC mixture throughout the entire temperature range. The pretilt angle effect in the physical parameters has also been studied. At T=20°C, the response time decreases to 25% and 35% for mixture ABC for 2° and 5° pretilt respectively in comparison to zero pretilt. On the other hand, at the same temperature for the ABD mixture these values are reduced by 16% and 35%, respectively.

Opis:
Po utworzeniu diecezji koszalińsko-kołobrzeskiej w 1972 r. biskup Ignacy Jeż ogłosił Skrzatusz diecezjalnym sanktuarium. Wieloletnie starania biskupa i salezjańskich kustoszy doprowadziły do uroczystej koronacji figury Matki Bożej Bolesnej w 1988 r. W 25. rocznicę tego wydarzenia rozpoczęto wydawanie Rocznika Skrzatuskiego. Redakcja czasopisma postawiła sobie za cel propagowanie na szerszą skalę maryjnego sanktuarium. Pojawiają się w nim artykuły także o tematyce biblijnej i mariologicznej. Główny nurt jednak stanowią treści związane z samym sanktuarium i trwającym tam nieprzerwanie kultem Matki Bożej Bolesnej. Wydana niedawno transkrypcja manuskryptu ks. Andrzeja Józefa Delerdta umożliwiła szerokiemu gronu czytelników zapoznanie się z ciekawym źródłem z drugiej połowy XVIII w. Prezentowany, dotąd nieznany dokument, odsłania podstawę ogłoszenia Piety Skrzatuskiej jako cudownej przez biskupów poznańskich w drugiej połowie XVII w. Komisarze wysłani przez administratora diecezji, ks. Jana Braneckiego, przedstawili władzy duchownej dokument, w którym udowodnili, że to, co dzieje się w Skrzatuszu, ma podłoże działania Bożego. Autor w niniejszym artykule osadza dokument na tle sytuacji regionu w połowie XVII w. Kolejnym krokiem będzie wydanie tekstu dokumentu w języku oryginalnym z całym krytycznym aparatem.
After the creation of the Koszalin-Kolobrzeg (Kołobrzeg) Diocese in 1972, Bishop Ignacy Jeż proclaimed Skrzatusz a diocesan sanctuary. Many years of efforts of the bishop and Salesian custodians led to the solemn coronation of the statue of Our Lady of Sorrows in 1988. On the 25th anniversary of this event, the publication of the Rocznik Skrzatuski began. The editorial board of the magazine set itself the goal of promoting the Marian sanctuary on a larger scale. There are also articles on biblical and Mariological topics. The mainstream, however, is the content related to the sanctuary itself and the uninterrupted cult of Our Lady of Sorrows there. A recently published transcript of the manuscript of Fr. Andrzej Józef Delerdt enabled a wide group of readers to get acquainted with an interesting source from the second half of the 18th century. The presented, so far unknown document reveals the basis for proclaiming Pieta Skrzatuska – as miraculous by the bishops of Poznan (Poznań) in the second half of the 17th century. Commissioners sent by the administrator of the diocese, Fr. Jan Branecki, presented the clerical authority with a document in which they proved that what was happening in Skrzatusz was based on God’s actions. In this article, the author places the document against the background of the region’s situation in the mid-17th century. The next step will be to publish the text of the document in the original language with the entire critical apparatus.

Opis:
This paper proposes a new adaptive sliding mode control scheme for achieving coordinated motion control of a group of autonomous underwater vehicles with variable added mass. The control law considers the communication constraints in the acoustic medium. A common reference frame for velocity is assigned to a virtual leader dynamically. The performances of the proposed adaptive SMC were compared with that of a passivity based controller. To save the time and traveling distance for reaching the FRP by the follower AUVs, a sliding mode controller is proposed in this paper that drives the state trajectory of the AUV into a switching surface in the state space. It is observed from the obtained results that the proposed SMC provides improved performance in terms of accurately tracking the desired trajectory within less time compared to the passivity based controller. A communication consensus is designed ensuring the transfer of information among the AUVs so that they move collectively as a group. The stability of the overall closed-loop systems are analysed using Lyapunov theory and simulation results confirmed the robustness and efficiency of proposed controller.

Opis:
Sixty female prawn seed collectors and 60 female control subjects from Sajenakhali and Sandeshkhali blocks of Sunderbans, West Bengal, India, were randomly selected to evaluate and compare musculoskeletal disorders and physiological stress. The control group was engaged in domestic work involving minimum handintensive activities. The modified Nordic musculoskeletal questionnaire and rapid entire body assessmentwere used. Most subjects suffered from discomfort in different body parts, especially in the lower back (98%), knees (88%), shoulders (75%), ankles (70%) and feet (67%). This study reveals that female prawn seed collectors suffer from significant physiological load and extreme physiological stress due to prolonged working hours in a standing posture and excessive work pressure. Consequently, all these factors affect female prawn seed collectors’ health and work performance.

Opis:
The study aims to elucidate the impact of organic inputs on strength and structural stability of aggregates in a sandy loam soil. Tensile strength, friability and water stability of aggregates, and the carbon contents in bulk soil and in large macro (>2 mm), small macro (0.25-2 mm), micro (0.053-0.25 mm) and silt+clay size (<0.053) aggregates were evaluated in soils from a long-term experiment with rice-wheat rotation at Modipuram, India, with different sources and amounts of organic C inputs as partial substitution of N fertilizer. Addition of organic substrates significantly improved soil organic C contents, but the type and source of inputs had different impacts. Tensile strength of aggregates decreased and friability increased through organic inputs, with a maximum effect under green gram residue (rice)-farmyard manure (wheat) substitution. Higher macroaggregates in the crop residue- and farmyard manure-treated soils resulted in a higher aggregate mean weight diameter, which also had higher soil organic C contents. The bulk soil organic C had a strong relation with the mean weight diameter of aggregates, but the soil organic C content in all aggregate fractions was not necessarily effective for aggregate stability. The soil organic C content in large macroaggregates (2-8 mm) had a significant positive effect on aggregate stability, although a reverse effect was observed for aggregates <0.25 mm. Partial substitution of nitrogen by organic substrates improved aggregate properties and the soil organic C content in bulk soil and aggregate fractions, although the relative effect varied with the source and amount of the organic inputs.

Opis:
The low back pain risks in a beef skinning operation at a high stand kill floor workstation was evaluated. The increases in compressive forces at lower back (L5/S1) between normal slump (back angle 25°, measured in the sagittal plane) and severe (45°) and between normal slump and very severe (70°) bent back postures were 387 N or 28% and 616 N or 45%, respectively. The high spine load coupled with high level of repetition can have a high probability of fatigue failure in the spine structural members. Non-neutral back posture for a large portion of the total work time can be a low back pain risk factor. The videotape analysis showed that the times involved during the task performance for the bent back (more than 25°) and severe bent back (more than 45°) were 48.4 and 33.5% of the total cycle time, respectively. The upper limit from OWAS (Ovako Working Posture Analysis System) for bent back posture is 30% of the total cycle time. The bent and twisted back posture (both more than 25°) time was 10.4% compared to OWAS limit of 5%. This indicated that actions are needed in the near future to alleviate the risk of low back pain. Ergonomics redesign of the workstation was recommended for the operation.

The isometric strength profiles of male and female paraplegics were determined for pull and push strengths in the normal, maximum, and extreme working reach envelopes. A computerized isometric strength measurement system was designed and constructed for the purpose. The strongest pull location was at extreme reach vertically above the shoulder and the strength values for males and females were 473 and 318 newtons (N), respectively. The strongest push location was at maximum reach, at vertical ($) angle of 45° and at horizontal (6) angle of 45° for males and at 0° for women and the strength values were 235 and 172 N, respectively. The nature of the strength profiles was found to be similar for both the sexes. The pull and push strengths of the female were 77 and 68% that of the male, respectively.

The effect of reach levels, horizontal angles, and vertical angles on isometric pull and push strengths of male and female was determined. Highly significant increases in men’s push strength were found between extreme to maximum reaches, and from extreme to normal reaches. However, for women’s push strength, a significant increase was found only between extreme to maximum reach. Significant or highly significant increases were found in men’s and women’s pull strength between the horizontal angle (0) sagittal through the active shoulder (90°) and other angles (0, 45, and 135°). However, for men’s push strength, highly significant increases were found between the horizontal angle 45° from the frontal plane, and other angles. For women’s push strength, significant or highly significant increases were found between the horizontal angles 0° and angles of 90 and 135°. For men’s and women’s pull strength, significant or highly significant increases were found between the vertical angle (), 90°, and other angles (-20, 0, and 45°). Similar increases were found for women’s push strength between the 45° angle and other angles. In the design of a workstation for paraplegics that requires pull and push forces, consideration must be given to the spatial factors.

The isometric pull and push strength profiles of males and females were determined in seated and standing positions in the workspace. The strongest pull strength location was at extreme reach vertically above the shoulder for both males and females. The greatest pull strength of 400 Newtons (N) for males was recorded in the seated and standing positions. Females. pull strengths in the seated and standing positions were 222 and 244 N, respectively. The strongest push strength was always at the maximum reach at the overhead location. Males. maximum push strength was 227 N in the seated position and 251 N in the standing position. Females’ maximum push strength was 96 N in the seated position and 140 N in the standing position. On the average the strength in the standing position was 79% of the seated position. The push strength was 71% of the pull strength and females were 56% as strong as males.

Opis:
The effect of reach levels, horizontal angles and vertical angles on isometric pull and push strengths of males and females in standing and seated positions was determined. The effect of reach levels on strength varied as a consequence of force direction, working position and gender. Reach level has a significant effect on women's pull strength in the seated position and on push strength in the standing position. The strength value was significantly greater in the extreme reach than in maximum or normal reach. Vertical angle ö had a significant effect on strength consistently in all cases. Strength values increased significantly with the increase of ö angles from 0º to 45º to 90º. The horizontal angle è had a significant influence only on the pull strength of standing and seated men and standing women (not seated woman). The maximum strength was significantly greater at è = 90º.
