점액성 위암과 점액성 대장암은 각각 드물게 발생하는데 점액성 위암의 근치적 수술 후 10년이 지난 후에 복막 전이를 동반한 점액성 대장암이 발생한 증례가 있어 보고하는 바이다. Mucinous gastric and colon carcinoma is rare histopathologic type of each carcinoma. We report a case of metachronous mucinous carcinoma of colon in 74-year-old female, 10 years after curative gastric surgery. She came to hospital with pain on right upper quadrant. Abdominopelvic computed tomography showed mucinous carcinomatosis peritoni with descending colon cancer. We detected the descending colon cancer by colonoscopy and confirmed mucinous carcinoma by biopsy.

Composite skew plates are aesthetically appealing light weight structural units finding wide applications in floors and roofs of commercial buildings. Although bending and vibration characteristics of these units have received attention from researchers but the domain of first and progressive failure has not been explored. Confident use of these plates necessitates comprehensive understanding of their failure behavior. With this objective, the present paper uses an eight noded isoparametric finite element together with von-Kármán’s approach of nonlinear strains to study first ply and progressive failure up to ultimate damage of skew plates being subjected to uniform surface pressure. Parameters like skew angles, laminations and boundary conditions are varied and the results are practically analyzed. The novelty of the paper lies in the fact that the stiffness matrix of the damaged plate is calculated by considering material degradation locally only at failed points at each stage of first and progressive failure and as a result, the present outputs are so close to experimental findings. Interpretation of results from practical angles and proposing the relative performances of the different plate combinations in terms of ranks will be of much help to practicing engineers in selecting the best suited plate option among many combinations.

An experiment was conducted to evaluate the effects of nitrogen supplementation through urea-molasses multinutrient block (UMMB) on the performance of dairy cows fed good quality forage based diets with rice straw as a night feeding. A total of 10 multiparous crossbred dairy cows in their early lactation were grouped into two categories based on their breed, parity, body weight, milk yield, milk fat and protein contents and daily fed a chopped CO-3 grass (Pennisetum purpureum × Pennisetum americanum; hybrid Napier) ad-libitum, 1 kg of dairy cow concentrate feed during the day time and 5 kg of rice straw (dry matter basis) at night as the basal diet (control) for 5 wk. In addition to the basal diet, the treatment group received 300 g of crushed UMMB daily throughout the experimental period. Cows were milked twice daily and the milk yields were recorded. Milk and feed samples were collected weekly for chemical analysis. Supplementation of UMMB had no significant effects (p>0.05) on straw intake, daily milk yield, contents and yields of milk constituents such as milk fat, protein, lactose and solids-non-fat. In addition, milk urea nitrogen content were not affected (p>0.05) by UMMB supplementation. However, numerical increments in all the parameters measured were observed during the study in cows fed diets supplemented with UMMB. It can be concluded that nitrogen supplied through UMMB had no effects on production performances of dairy cows in this study.

Smart Agroforestry (SAF) is believed to be one of the alternative solutions in implementing sustainable forest management to achieve the community welfare. SAF provides agricultural and silvicultural knowledge and practices that aims not only for recovering the environmen- tal attributes but also for increasing farmers resilience. However, the benefits of agroforestry related to soil fertility in optimizing the land productivity and governing the community live- lihood are often overlooked and have not been well discussed. This review aims to describe how smart agroforestry practices in various regions in Indonesia and several other countries have significantly contributed to maintaining soil fertility and increasing crop production while assuring profitable benefits for the community. This review paper focuses on discus- sing the role of SAF in sustaining soil fertility and community livelihood in tropical and non- tropical regions. The review article was based on a synoptic review approach to SAF and Soil Fertility-related relevant publications and nationwide experiences. The review compiled and analyzed information from national and international research papers in various online scientific journals, conference proceedings and relevant books, to gain a comprehensive understanding of the topic being discussed. The study utilized a qualitative approach and drew upon primary and secondary sources based on a systematic review. Agroforestry has a significant role in recycling soil nutrients from the materials in the surrounding environment. SAF influences soil fertility physically, chemically and biologically. SAF practices in both wet and dry lands can contribute significantly to the community’s income. This review unveils the latent potential and the role of SAF in sustaining soil fertility that supports the community’s livelihood and can serve as impetus for future research.
Total Phenolic and Starch Content of Arrowroot Tuber in The Agroforestry System

Indonesia’s tropical forest management faces several challenges owing to the growing demand for forest resources and increasing population. The forestry sector plays a significant role in supporting food security programs by harnessing the potential of forest resources. One solution to sustainable forest management and optimal forest land use is agroforestry techniques. Arrowroot (Maranta arundinacea) is tolerant to heavy shade and is a promising functional food crop that can contribute to food security programs. Starch content in arrowroot tuber plays an important role in meeting nutritional requirements and overcoming several health problems. Arrowroot tubers also contain phenolic compounds, the largest group of compounds that act as natural antioxidants in plants. This study aimed to analyze the total phenolic and starch contents of arrowroot tubers cultivated in agroforestry systems. We used a Randomized Complete Block Design with a planting pattern as treatment for the species combinations of Falcataria moluccana þ arrowroot (FA), F. moluccana þ arrowroot þ Amomum cardamomum (FAC), and monoculture arrowroot (MA) with three blocks/replications. The arrowroot tubers were harvested from nine-month-old plants and composite samples representing each treatment were analyzed for total phenolic and starch contents. The total phenolic content in the arrowroot tubers was determined using the Folin-Ciocalteu reagent. Starch content was measured using the Modified Somogyi method, which involves preparing reagents, followed by hydrolysis and the reducing sugar determination methods. The results revealed that the planting pattern significantly affected starch content. The highest starch content was observed in the MA pattern of 23.99%, followed by the FAC and FA planting patterns of 22.75% and 18.44%, respectively. The planting pattern did not significantly affect phenolic content. The MA, FAC, and FA patterns yielded the highest to lowest phenolic contents of 218.02, 212.62, and 210.04 mg/g, respectively. Furthermore, the planting pattern significantly affected the total phenolic of tuber yield per plant, with the highest value of 214.48 mg yielded by MA pattern. Thus, agroforestry practices can maintain the phenolic and starch content of arrowroot tubers. The development of arrowroot in agroforestry system will be prospective not only for meeting food demand, but also for supporting forestry multi-business and social forestry programs to achieve sustainable forest management.
