Oil palm biomass is widely known for its potential as a renewable resource for various value‐added products due to its lignocellulosic content and availability. Oil palm biomass biorefinery is an industry that comes with sociopolitical benefits through job opportunities, as well as potential environmental benefits. Many studies have been conducted on the technological advancements of oil‐palm biomass‐derived renewable materials, which are discussed comprehensively in this review. Recent technological developments have made it possible to bring new and innovative technologies to commercialization, such as compost, biocharcoal, biocomposites, and bioplastics. 相似文献

Scanning electron microscopy (SEM) of second-stage juveniles (J2), males, and females of Meloidodera floridensis, M. charis, M. belli, and Verutus volvingentis reveals detailed characteristics of the head region, lateral field, phasmid, body striae, vulva, and perineal region. In M. charis and M. belli the en face pattern conforms to a basic pattern in which the labial disc is surrounded by six lips (sectors) of the first head annulation. In J2 the head has additional annulations, whereas in males annulation is replaced by longitudinal blocks. Conversely, J2 and males of M. floridensis and V. volvingentis each have a unique derived face pattern with fusion of various lip components and with head annulation. All six lips of females of M. charis and M. belli are fused, whereas females of M. floridensis and V. volvingentis have distinct lateral lips. Lateral fields vary among species, with only slight differences at the anterior and posterior ends of the lateral lines and in the spatial relation of the lines to phasmid openings. Phasmid openings are present in adults of Meloidodera spp., but were not observed in adults of V. volvingentis; in this respect, the female perineal pattern of Verutus is different from Meloidodera spp, The very large vulva (± 48 μm long) of V. volvingentis is in sharp contrast to the minute vulva (± 6 μm long) in a population of M. charis from San Bernardino. Morphological characters revealed by SEM will be most informative when investigated throughout Heteroderidae and incorporated with additional characters for a phylogenetic analysis of the family. 相似文献

Biopulping can be an alternative to the traditional methods of pulping. Biopulping use fungi that are known to be able to degrade wood as well as lignin constituent of wood. Amongst these white
rot fungi are the most proficient biodegrader. The fungus is non sporulating and is a selective lignin degrader. It colonizes
either on living or dead wood and decomposes all wood polymers including lignin and extractives making it to be extremely
potential to be used in biopulping. The process of biopulping reduces the utilization of chemical in pulping industry and
help in decreasing the environmental hazard caused by normal pulping. The present review deals with diverse aspects of biopulping
and their ecological as well as economic significances. 相似文献

Table olive processing wastewaters constitute a dangerous environmental problem in the Mediterranean countries because of their large volumes, high organic matter and salt concentration. The quantity and the characteristics of wastewaters produced, and thus, their environmental impact, varied depending on the season, varieties, soil and process employed. Several chemicals, biological and combined technologies have proven effective at bringing down organic pollution and toxicity of these effluents. Advanced oxidation processes have recognized as highly efficient treatments for the degradation of organic matter. Nonetheless, complete mineralization is generally expensive without salt removal. Biological processes are the most environmentally compatible and least-expensive treatment methods, but these operations do not always provide satisfactory results. This article surveys the current available technologies and suggests an effective, cheaper alternative for the recycling and the valorization of green table olives wastewaters. 相似文献

The structure of the granulosa in reptilian sauropsids varies between groups. We investigated the follicle development in the desert lizard Scincus mitranus. In the germinal bed, oogonia, and primary oocytes were identified and found to be interspersed between the epithelial cells. Previtellogenesis was divided into three stages: early, transitional, and late previtellogenic stages. During the early previtellogenic stage (diplotene), the oocyte is invested by small epithelia cells that formed a complete single layer, which may be considered as a young follicle. The transitional previtellogenic stage was marked by proliferation and differentiation of the granulosa layer from a homogenous layer consisting of only small cells to a heterogeneous layer containing three cell types: small, intermediate, and large cells. The late previtellogenic stage was marked by high-synthetic activity of large cells and the initiation of cytoplasmic bridges between large granulosa cells and the oocyte. Small cells were the only type of granulosa cells that underwent division. Thus, these cells may be stem cells for the granulosa cell population and may develop into intermediate and subsequently large cells. The intermediate cells may be precursors of large cells, as suggested by their ultrastructure. The ultrastructure of the large granulosa was indicative of their high synthetic activity. Histochemical analysis indicated the presence of cholesterol and phospholipids in the cytoplasm of large cells, the zona pellucida, among the microvilli, in the bridges region, and in the cortical region of the oocyte cytoplasm. These materials may be transferred from large cells into the oocyte through cytoplasmic bridges and provide nutritive function to large cells rather than functioning in steroidogenesis or vitellogenesis. 相似文献

Summary Rhodes grass (Chloris gayana) was grown under glasshouse conditions on soils that had previously grown from 1 to 6 soybean (Glycine max) or Siratro (Macroptillium atropurpureum) crops. Soil mineral N contents at sowing were higher in Siratro-cropped than soybean-cropped soils and increased with cropping history.Yields of Rhodes grass at the first harvest (14 weeks) were related to soil mineral N levels at sowing by the relationship Y=138.7 (1–0.917e–0.012x). Grass grown on all soybean soils was responsive to N at both harvests (14 and 28 weeks). Grass grown on soil that had grown three or more Siratro crops was non-responsive to N at the first harvest but responses to N were recorded on all Siratro soils at the second harvest.The amount of N removed by the grass crops was small in relation to the total amount present in the soil system. This resulted in no change in soil total N levels over the two crop periods.These results highlight the need to study N dynamics in crop systems rather than continue to measure N pool sizes when evaluating the contribution of biologically fixed N to the nutrition of subsequent non-legume crops. 相似文献

OBJECTIVE--To define the relation between mood and autoimmune thyroid dysfunction during the eight months after delivery. DESIGN--Double blind comparison of the psychiatric status of women positive and negative for thyroid antibodies. Clinical examination and blood sampling for free triiodothyronine and thyroxine, thyroid stimulating hormone, and thyroid antibody concentrations at four weekly intervals. Psychiatric assessment at six, eight, 12, 20, and 28 weeks post partum. SETTING--Outpatient department of district hospital. PATIENTS--145 antibody positive women and 229 antibody negative women delivering between August 1987 and December 1989. MAIN OUTCOME MEASURES--Thyroid status. Number of cases of mental ill health by the general health questionnaire, research diagnostic criteria, Hamilton 17 item depression scale, hospital anxiety and depression scale, and Edinburgh postnatal depression scale. RESULTS--Six weeks after delivery the general health questionnaire showed 62 (43%) antibody positive women and 65 (28%) antibody negative women had mental ill health (chi 2 = 8.18, p less than 0.005). Follow up of 110 antibody positive and 132 antibody negative women showed significantly greater depression by research diagnostic criteria in antibody positive women (47%) than antibody negative women (32%) regardless of thyroid dysfunction. Antibody positive women showed higher mean scores for depression on the Hamilton (6.01 v 3.89, p = 0.0002), Edinburgh (7.45 v 5.92, p = 0.031), and hospital depression scales (4.95 v 3.79, p = 0.003). CONCLUSION--Depressive symptoms are associated with positive thyroid antibody status in the postpartum period. 相似文献

The effect of human normal serum (HNS) on Pseudomonas pseudomallei was determined. It is apparent from our data that the organism is resistant to the normal serum bactericidal mechanism. Ancillary experiments to confirm this serum-resistant property of P. pseudomallei were done by examining the effects of growth phase conditions of the bacteria (i.e., logarithmic and stationary phases) and different buffered systems used as diluent in our bactericidal assay. Results obtained showed similar degree of resistance to serum bactericidal killing by 5 strains of the organisms tested. The possible survival advantage of serum-resistant property to P. pseudomallei as bacterial pathogens known to invade the blood stream is discussed. 相似文献
